This is the best way I’ve ever heard iPhone batteries, or batteries in general to be honest, explained. Thanks again Tom, I always look forward to new videos.
I got my iPhone 15 Pro Max on launch day and charge to 80%. I usually end to day with just over 20% left. I use an old Apple charger (I think it came with my iPhone 6) which is only 5w. On days I use more battery, I’ll charge up from around 20% just enough to get me to the end of the day. I avoid high wattage chargers and wireless charging. At 1 year old the battery had 260 cycles and 100% health. Even I was impressed.
@@TrailBikeMike I use a regular 20W charger, but use a portable fan blowing on the back of the iPhone when charging. I have the charge limit set to 80%, have a similar amount of cycles and also 100% health :)
My charger is around 33w and I charge it to 100% most times, and after a year the battery was still at 100%, this was the case with my 12pm, 14 pm, and 15pm. So for me all this charging only to 80% is pointless for normal use.
That is surprising given you let your battery get so low, so often. I try not to let mine drop below 40%. My XS Max was at 95% capacity at 5 years old when traded it in for a 15 Pro max. I usually charged that phone to 100% and tried to never let it fall below 40%. With my new phone I have the limit set to 80% and am still at 100% capacity after a year and 167 cycles.
@@gigglybeast The saying is dont go below 20, surely you can go below 40 without any problems, you want to have some battery, if you set the limit to 80% and dont go below 40% that gives you only 40% in total. That is way to little to get most people through a day unless you don't use the phone much or dont mind charging it often.
@@artfartzy - I do charge multiple times a day and keep it between 40 and 80. It’s quite easy to charge every time I get in my car or sit down in my house. The car is pretty much automatic as the place to lay my phone charges wirelessly. I’ve always heard it’s best not to go below 40%. The 20% “saying” you reference is new to me and 40% has served me well with my phones and iPads.
This is the main reason I got 16 Pro Max - the largest possible capacity. I charge my phone in the morning to 80% and with my average usage I end up at 45-50% by next morning. This is perfect for battery life, because lithion batteries prefer "shallow" charging. Long story short, if you want to preserve your battery life as long as possible, charge only up to 80% and do not discharge to low percentage, under 20-30% it put more stress on it. Always use wired chargers, charge slowly and for gods sake create a simple automation that will put your phone into low power mode in times when you are not using it, like while you sleep.
@@TekkitsWorkshop I have put my phone to charge it was supposed to stop at 85%, I went outside and when I came back it was 100% do we have to manually unplug after 85 or does the phone stop itself at 85??
@@roshan7920 It should stop, but it not always do it from my experience. You could buy one of those wifi controlled outlets and turn it off via shortcut.

Great advise but can you clear these confusions too? 1. Will plugging the charging in and out too often in short intervals harm the battery? For example, I just plugged in the charger and I had to unplug it for a few minutes. I plug it in again but need to unplug it for some wierd reasons and again I plug it in. 2. Does using a phone cooler while charging help protect the battery or is there no point at all? I always charge my phone with a cooling radiator in hopes it doesn't heat up my battery.
@@GoodMindNepal 1. No, it s completely fine 2. You don t have to do that just take the case out if you have one and if you want and let the phone to its thing, don t worry to much
I tell everyone pretty much exactly what you have said here particularly the "background" app thing and the 0% thing. One thing I also add when I explain this to people is that the phone is there to serve you, you didn't buy a job as a manager when you got it.
I’d take that level of warmth for a shorter phone life… I love in the south of England and our summers have been sh1t. I’ve sailed in the south Ionian and I’d certainly give up my phone to live in that beauty. What a lovely country you have 👍🏻👍🏻👍🏻
I have a USB device called a “Chargie”, which automatically limits the charge to any user selected figure. I mostly use 80% as top of charge. (Occasionally I’ll need to top it up a bit during the day- which is dead easy.) My iPhone 14, bought when they were released, is still showing 97% state of health. I keep it cool, and charge it slowly. And yes- my wireless charger has a fan. My previous phone, an iPhone X, also still had great battery health when I traded it.
I got my iPhone 12pro on Jan 14 2024, i charge it overnight with apple 5W charger…and sometimes I occasionally charge it with 20W anker charger. My battery health is currently 100%. Using iOS18.0.
About force quitting apps it is known and tested that some apps is draining on the battery while left open, specially social media apps like FB and IG and others. And also apps that uses your location services such as mapps and weather. Also I like to keep the app switcher clean, and if you keep every app open it will just result in a clutter. Specially if you work with 2-3 apps at the same time, and then have to swipe through lots of other apps to find the one you need in the app switcher. So unless you have an app that you use many times a day I dont see the need to keep it open.
TBH, I don’t really think about battery charging too hard. Mainly because I don’t have a lot of great control over when it’s charged. Yes, I can choose to charge it at night. But, one of the features I use all the time is Car Play. In my car I have to use a USB cable. Ergo, to use Car Play I will be charging my phone. No major control about that. So, I just don’t worry too hard. My phone seems fine thus far. My previous phone was an iPhone 8 and it lasted 5 years before the battery life got annoying in the sense I had to charge it any moment I got. It’s comforting to know a lot of the common suggestions are myths, at least with the current version of technology.
So happy to have stumbled across your channel as I navigate my way around my new iPhone 16. Clear concise information. Thank you. I have one question. Everyone talks about heat but what about cold. I live in Thailand and my iPhone is attached in the car in front of theair-conditioning vent. Do you think this constant flow of cold air set a 25 Celsius is bad for the battery or even the screen? On my iPhone 12, I discovered a disfiguring in the centre of the screen and I wonder if this could’ve been caused by the cold air.
iPhone 15PM 204 cycles and still 100%. I use only the apple 20w wired charger , 80% limit and now I use only wireless apple car play. A game changer for me since I’m on the road all the time.
Grt video One query I have relates to camera apps native and black magic. If these are not shut down I have experienced significant battery drain (I would add that this was probably owing to the phone coming out of sleep accidentally - being in a pocket). Would you say that the apps can be kept open in the background without having the phone live without significant battery drain?
Are these suggestions appropriate for AirPods Pro II mainly curious about leaving them on charge overnight. First time I’ve watched one of your videos. I’ll definitely be back, good job! Thanks
Thanks for your explanation. Is it still good for your IPhone battery to charge it to a 100% every now and then. I charge to max 80-85% but is it better sometimes charge to a 100%
Hi BRIAN HERE just adjusted my new 16 pro max 1Tb battery to 80% however when should I recharge my phone ? & should I turn off over night some one said NO ! Cheers Brian
I always force quit all my apps at the end of the day before I place it on the charger overnight, because like to start each day with a fresh boot-up of each app that I might use each day.
@@MystifyMe97 I reboot all the apps I use daily in the morning while still connected to the charger. I also give my phone random daily charges, so my battery is rarely less than 50%.
Super impressed with iPhone 15+ that I got new in October 2023. 238 cycles in that time and battery health still showing at 100% health. I’ve had it set to max out at 80% charge, with only overriding that every now and then if needed. Really pleased with that, as I essentially just got the iphone with the best battery reviews at the time. Great video as always :-)
The first video I have seen from your channel and I got to say it was so informative! Could you do one for Macbooks? For instance, I want to get a monitor but I am concerned that plugging my Macbook to a monitor with power delivery for long durations would result in my Macbook staying at 100% for a long time. Would that impact my Macbook battery health?
The analogy I use is this: when you buy a new car, imagine that the gas tank begins to shrink over time. Initially you can put 15 gallons in it and after a year it shrinks to 14.5 gallons capacity. After two years you can only put 13 gallons in the tank. And so on.
As you also say in the video, the battery's ultimate enemy is heat. Especially too much of it, but also too little. Too much heat equals temperatures of 27 degrees Celsius (about 80 degrees f) After that, the physical degradation of the battery begins. At first it goes slowly, but it accelerates as the temperature rises. Frost can also damage the battery, especially if you try to charge while the battery is frozen. There, the chemical effect (read: the liquids in the battery) cannot work as it should. This can damage both the anode and the other elements. My best advice is: Charge often, with a slow charger (to avoid excess heat) or make sure to cool the phone while charging. Do not charge when the phone is around the freezing point or below. Do not place the phone in direct sunlight for a long time. If you play very demanding games or use other applications that make the phone very hot, buy a fan for the phone that can keep it cool. And as is also written elsewhere - 20-80% charging keeps the battery happy! the rumor that the battery must be charged up to 100% once in a while and discharged all the way to 0% does not originate from the battery, but is a misunderstanding that has arisen because many electric cars benefit from this. But it is not for the battery, but for the sake of the calibration of the BMS, which in an electric car must keep track of many battery cells - up to several hundred, and these must be balanced with each other. In a phone there is only one battery cell, so this is unnecessary.
I've got two problems with charging my iPhone15 Pro: - Charging overnight with a 5W-charger doesn't get my phone to charge all the way up (limit set at 90%). Mostly it only gets me around +30% charging power while asleep (about 8 hours). I thought slower charging is better for my battery, so I'm using 5W instead of a 20W charger I also got lying around. Is this also a myth? Am I better off using 20W so I can start the day with 90%? - My main battery drainer is Apple Music with bluetooth headphones or casted to a smart speaker. I do this a lot during the day (roughly 5-6 hours a day). Is it normal this is using so much battery life? My phone can go from 90% to 20% on a regular basis during one day and it's really new (two months old). I think my old iPhone13 Mini lasted longer.
iPhone 14 Pro Max user I use since 2022 and since I charge it daily 95% to 100% and it gets me thru the day maybe at evening I need some more batter I just plug it in and until I take a shower it’s done charging to 85% and I’m good, also I’m a very heavy user use while charging, play games and despite all of this up until today I have 87% battery health. You should really charge your iPhone however you want it knows to take care of itself more than you do also battery replacements cost just about $99 so never ever think about it also avoid too much heat exposure that’s the thing batteries hate the most especially lithium-ion ones used on iPhones and as well as letting the phone drain to 0%.
Not really for normal use. If doing weird stuff like downloading pirated things through torrents or it’s jailbreaked with an alternative App Store then maybe it has a small chance of preventing malware on your phone
I believe everything said to be true except one: in my experiences; there are multiple time that I could collocate many of my previous iPhones (also other smart phone) battery life degradation to them being use while they are charging. (Now i should note, that my last iPhone that got affected by charging-in-use was iPhone-11 which may not necessary translate to today's tech.)
I am going to set up charging limit at (generally) 85% and use a 12 watt/2.4 ampere charging connection on my iPhone 16 Plus. Hopefully, the battery will last way longer that way!
Appreciate the video very much, but no mention of accumulating excessive cycles by charging to 100% once or multiple times per day. I'm still wondering if that habit can shorten the battery life/function.
@@JasVmitten charging once a day or multiple times a day doesn’t make a difference to the cycle count. For example, charging from 0 to 100% is the same cycle as charging from 50 to 100% twice.
12:11 The phone could do adjustments itself indeed, but only to a certain degree. It could make sure the battery doesn’t explode, but it couldn’t prevent the battery to degrade faster due to heating, user actions are also important.
I'm just curious, so what is the purpose of having a 100% capacity phone if I should only charge it up to 80% in order to preserve the battery health does that mean I cannot use my phone to its full capacity/ability to last, I am now realizing it's to complicated to take care of an iPhone if you just want to enjoy using it. So is it also okay to charge 20% - 100%? or 30% - 100%?
How about calibrating your iphone battery when buying it for the first time? Like it should go from 100% to 0% in order for the phone to properly display the battery percentage. Was it all just a myth?
Charge, using a cable, as much as you can, between 40% - 80%. Once every three months charge to 100%. Never let it die or stay too long on 100%. I still have an iPhone 11, with 100% battery health/capacity. Never use wireless charging as it affects the battery.
Keep charge between 20 and 80% and avoid extreme fast charging and temperatures as well as wireless charging. Is that so difficult? Especially the new battery charging limit in IOS 18 should help a lot and will hopefully be extended to most devices including iPads.
Seems like if you have a battery charge limit set on a 16 Pro, it will still charge to 100% every other week or so. I've set mine to 85% limit, and last night and at least one night a couple weeks ago, it charged to 100%.
So most of the things that now improve battery life or additional settings are only available on iPhone 15 and later even though most of them are software changes.
With many of the new cars have wireless chargers to set you phone on. Many people put their phone on the charging pad every time they get in the car. Often, if they are in & out of the car a few times the phone is out on & off the charger numerous times sometimes within short periods. Is this hard on the battery & how should you handle this situation??
Since iOS 18 upgrade my battery life as been shocking not changed the way I use it and now after about 4hrs is down to 55/60 % and it’s a newish battery replaced it on my iPhone 12 through the official Apple Store a few months ago battery health is at 100% had no issues before I upgraded to iOS 18
I find it hilarious that TH-cam is acting like a butt and being unresponsive so I gotta close it out but I’m too busy watching your video. Haha. Good content 💯
I bought a iPhone 15 pro max 2nd hand around a month ago,it was only switched on in march but the battery health is now at 92%,dreadful I know and how has it lost so much health in 7 months,cycle count is at 256,he lad I bought it from must of had it on constantly and charging it maybe twice a day,I don’t have social media or games on my phone I can get at least 3 days between charges but the health has dropped 2% since I started to use it,any advice?
Been charging my 15 pro max wireless for 7months&i have not lost a single %,trick i done was set it to go on low power mode in the shortcuts while its charging&its hardly heated up
i got my iPhone 13 and with 86% battery capacity, i think my phone is degrading at quite a good pace, and i didn't change my charging habit to accommodate at all
I used low power mode for 3 years, charging most nights to 80%. When I stopped, my battery degraded quickly after charging overnight to 100% and letting it go to 0. After 3 years my iPhone 13 base model was at 88% battery health yet it was dying quickly.
All batteries work this way. And wireless charging is a solution in search of a problem. How is plugging in a cable any less tedious than putting a device on a wireless charger? And I’ve had batteries swell in devices that were unused and in storage. It’s better to keep your battery charged on a somewhat regular basis.
I set my phone to charge to 90%. After the latest update, I noticed the phone charged to 100%. Opened the battery in settings, and the setting had not changed. I set it to 95%, then brought it back to 90%. It seems to work now, but I found it curious that this happened. I have an I-phone 15 pro, running 18.0.1.
I invested €1800 in an iPhone 15 pro max direct from Apple on release date. After 9 months my battery max capacity was only 89%. My iPhone 13 Pro Max was at 92% after 2 years. My battery only lasts 10hrs whereas my 13 I was getting 16hrs with same use and charging styles. Very disappointed. Apple say phone / battery is fine because I’m a heavy user. Not happy…
I got a used iPhone 15 around 5 days ago at 92% battery level with less than 300 cycle count, in those 5 days with only added barely around 3 more cycles (I know what a cycle is) it's already at 91% even though I keep the phone at 85% maximum charge and don't overheat it. Is that bad?
These are the little intricacies that piss me off, androids have had this battery limit settings for years but with iOS they only gave the iPhone 15 and 16 these battery charging limit privileges despite older iPhone using the same iOS updates it's ridiculous
I recently upgraded from an iPhone 10 to an iPhone 15 pro. The main reasons being that I was running out of storage but the main reason was battert life; it just died very quickly, to the point that the phone was unusable. I had all the usual battery saving settings engaged: location services off in almost apps, background refresh off for almost all apps, auto-lock set at one minute etc etc. but battery life was still terrible. Having got my new iPhone 15 I wiped the iPhone 10 and set it up as a new phone (I use it for another SIM contract) and now the battery is great. Settings shows: - Max capcity 85% - Peak Performance Capacity Very odd and I was wondering if anybody else has experienced this unexplained battery useaged? Thx
1 thing to add to point one all batteries are made in different factories. My iPhone Pro 15 Pro Max battery health dropped to 99% with 25 cycles. On my new iPhone 16 Pro has a higher battery health 120% iOS will only display 100%
I am constantly charging my iPhone on my wireless phone holder in my car while I am driving. I need to charge it because the Waze app is runing and draining the battery.
Any amount of wireless charging will harm your battery in the long run. Using a wireless charger with a fan, like the one in the sponsor spot, might help a little, but that would be like pointing a fan at your stove so your food wouldn’t burn while you’re cooking. The safest way to charge your battery is with a cable, not wirelessly.
@@MystifyMe97 my battery life always been great and I’m having best battery life on a iPhone I’ve ever had with my 16 pro max and I’ve had all the pro max phones from 11 pro max so it’s working well for me bro
Maybe, but here is an example, lets say: over weeks or even month you open 50 to 100 different apps on your phone, surely that will consume way more power than just opening few new apps on a given day.

From my experience the best to do it’s don’t let the battery drop below 20% and make sure you have optimised on of you want to keep charging to 100%
Hi BRIAN HERE just adjusted my new 16 pro max 1Tb battery to 80% however when should I recharge my phone ? & should I turn off over night some one said NO ! Cheers Brian
Should you turn off background refresh?
Thank you for your excellent video straight to the point!❤
I always force quit all my apps at the end of the day before I place it on the charger overnight, because like to start each day with a fresh boot-up of each app that I might use each day.
why, did you not listen to the video? It is not good for battery to do that.
@@MystifyMe97 Because I like to begin every day with fresh boot ups of all the apps that I regularly use.
@@HistoryNut-1701 good for you, but you do realise that is putting more strain on your battery by doing so, for no reason
@@MystifyMe97 I reboot all the apps I use daily in the morning while still connected to the charger. I also give my phone random daily charges, so my battery is rarely less than 50%.
Absolutely a waste of time and effort.
I heard that a magsafe charger is wearing on the battery, so I never use that. Also the charging is slower so I pfrefer using cable.
Super impressed with iPhone 15+ that I got new in October 2023. 238 cycles in that time and battery health still showing at 100% health. I’ve had it set to max out at 80% charge, with only overriding that every now and then if needed.
Really pleased with that, as I essentially just got the iphone with the best battery reviews at the time.
Great video as always :-)
I just got the 16 pro max a week ago, and I’m trying out only charging it to 85% like the experts suggest to see how it goes.
hw about the acefast 30w charger, is it safe for charging? basically charging for ip 16 pro
The first video I have seen from your channel and I got to say it was so informative! Could you do one for Macbooks? For instance, I want to get a monitor but I am concerned that plugging my Macbook to a monitor with power delivery for long durations would result in my Macbook staying at 100% for a long time. Would that impact my Macbook battery health?
The analogy I use is this: when you buy a new car, imagine that the gas tank begins to shrink over time. Initially you can put 15 gallons in it and after a year it shrinks to 14.5 gallons capacity. After two years you can only put 13 gallons in the tank. And so on.
As you also say in the video, the battery's ultimate enemy is heat. Especially too much of it, but also too little.
Too much heat equals temperatures of 27 degrees Celsius (about 80 degrees f) After that, the physical degradation of the battery begins. At first it goes slowly, but it accelerates as the temperature rises. Frost can also damage the battery, especially if you try to charge while the battery is frozen. There, the chemical effect (read: the liquids in the battery) cannot work as it should. This can damage both the anode and the other elements.
My best advice is:
Charge often, with a slow charger (to avoid excess heat) or make sure to cool the phone while charging. Do not charge when the phone is around the freezing point or below. Do not place the phone in direct sunlight for a long time.
If you play very demanding games or use other applications that make the phone very hot, buy a fan for the phone that can keep it cool.
And as is also written elsewhere - 20-80% charging keeps the battery happy!
the rumor that the battery must be charged up to 100% once in a while and discharged all the way to 0% does not originate from the battery, but is a misunderstanding that has arisen because many electric cars benefit from this. But it is not for the battery, but for the sake of the calibration of the BMS, which in an electric car must keep track of many battery cells - up to several hundred, and these must be balanced with each other. In a phone there is only one battery cell, so this is unnecessary.
I've got two problems with charging my iPhone15 Pro:
- Charging overnight with a 5W-charger doesn't get my phone to charge all the way up (limit set at 90%). Mostly it only gets me around +30% charging power while asleep (about 8 hours). I thought slower charging is better for my battery, so I'm using 5W instead of a 20W charger I also got lying around. Is this also a myth? Am I better off using 20W so I can start the day with 90%?
- My main battery drainer is Apple Music with bluetooth headphones or casted to a smart speaker. I do this a lot during the day (roughly 5-6 hours a day). Is it normal this is using so much battery life? My phone can go from 90% to 20% on a regular basis during one day and it's really new (two months old). I think my old iPhone13 Mini lasted longer.
what about if turning ur phone on once in a while helps the battery life? thank u! 🙏🏻
iPhone 14 Pro Max user I use since 2022 and since I charge it daily 95% to 100% and it gets me thru the day maybe at evening I need some more batter I just plug it in and until I take a shower it’s done charging to 85% and I’m good, also I’m a very heavy user use while charging, play games and despite all of this up until today I have 87% battery health. You should really charge your iPhone however you want it knows to take care of itself more than you do also battery replacements cost just about $99 so never ever think about it also avoid too much heat exposure that’s the thing batteries hate the most especially lithium-ion ones used on iPhones and as well as letting the phone drain to 0%.
is it advantageous to have a security app for your iPhone, i.e. Bitdefender, norton’s, mcafee, avg and others?
@@leerike694 No.
Not really for normal use. If doing weird stuff like downloading pirated things through torrents or it’s jailbreaked with an alternative App Store then maybe it has a small chance of preventing malware on your phone
very helpful thank you for your videos please keep them coming
I believe everything said to be true except one: in my experiences; there are multiple time that I could collocate many of my previous iPhones (also other smart phone) battery life degradation to them being use while they are charging. (Now i should note, that my last iPhone that got affected by charging-in-use was iPhone-11 which may not necessary translate to today's tech.)
I am going to set up charging limit at (generally) 85% and use a 12 watt/2.4 ampere charging connection on my iPhone 16 Plus. Hopefully, the battery will last way longer that way!
Appreciate the video very much, but no mention of accumulating excessive cycles by charging to 100% once or multiple times per day. I'm still wondering if that habit can shorten the battery life/function.
@@JasVmitten charging once a day or multiple times a day doesn’t make a difference to the cycle count. For example, charging from 0 to 100% is the same cycle as charging from 50 to 100% twice.
@@MarkLyen k thanks
I charge my phone to 100% always, everyday. It's just a phone and it should not hinder any of my normal habits.
12:11 The phone could do adjustments itself indeed, but only to a certain degree. It could make sure the battery doesn’t explode, but it couldn’t prevent the battery to degrade faster due to heating, user actions are also important.
Good info as usual
I'm just curious, so what is the purpose of having a 100% capacity phone if I should only charge it up to 80% in order to preserve the battery health does that mean I cannot use my phone to its full capacity/ability to last, I am now realizing it's to complicated to take care of an iPhone if you just want to enjoy using it. So is it also okay to charge 20% - 100%? or 30% - 100%?
Thank you for this!
optimal settings for battery health?
How about calibrating your iphone battery when buying it for the first time? Like it should go from 100% to 0% in order for the phone to properly display the battery percentage. Was it all just a myth?
You absolutely, 100% do not need to 'calibrate' your battery, not when you first buy the phone, nor later on.
Charge, using a cable, as much as you can, between 40% - 80%. Once every three months charge to 100%. Never let it die or stay too long on 100%. I still have an iPhone 11, with 100% battery health/capacity.
Never use wireless charging as it affects the battery.
Keep charge between 20 and 80% and avoid extreme fast charging and temperatures as well as wireless charging. Is that so difficult? Especially the new battery charging limit in IOS 18 should help a lot and will hopefully be extended to most devices including iPads.
Excellent video. Thank you.
Seems like if you have a battery charge limit set on a 16 Pro, it will still charge to 100% every other week or so. I've set mine to 85% limit, and last night and at least one night a couple weeks ago, it charged to 100%.
Another great video. Thanks much.
When I travel by car, I always put my phone close to the [way fresher] A/C so that it doesn’t overheat.
So most of the things that now improve battery life or additional settings are only available on iPhone 15 and later even though most of them are software changes.
With many of the new cars have wireless chargers to set you phone on. Many people put their phone on the charging pad every time they get in the car. Often, if they are in & out of the car a few times the phone is out on & off the charger numerous times sometimes within short periods. Is this hard on the battery & how should you handle this situation??
Since iOS 18 upgrade my battery life as been shocking not changed the way I use it and now after about 4hrs is down to 55/60 % and it’s a newish battery replaced it on my iPhone 12 through the official Apple Store a few months ago battery health is at 100% had no issues before I upgraded to iOS 18
I find it hilarious that TH-cam is acting like a butt and being unresponsive so I gotta close it out but I’m too busy watching your video. Haha. Good content 💯
I bought a iPhone 15 pro max 2nd hand around a month ago,it was only switched on in march but the battery health is now at 92%,dreadful I know and how has it lost so much health in 7 months,cycle count is at 256,he lad I bought it from must of had it on constantly and charging it maybe twice a day,I don’t have social media or games on my phone I can get at least 3 days between charges but the health has dropped 2% since I started to use it,any advice?
Which one is better: charging wirelessly or using cable?
Been charging my 15 pro max wireless for 7months&i have not lost a single %,trick i done was set it to go on low power mode in the shortcuts while its charging&its hardly heated up
i got my iPhone 13 and with 86% battery capacity, i think my phone is degrading at quite a good pace, and i didn't change my charging habit to accommodate at all
I used low power mode for 3 years, charging most nights to 80%. When I stopped, my battery degraded quickly after charging overnight to 100% and letting it go to 0.
After 3 years my iPhone 13 base model was at 88% battery health yet it was dying quickly.
Thank you. Your videos are always very helpful.
why its not working battery charge limit on iphone 16 pro? i set on 85% and its charge till 100%? please help:)
BTW, Your recommendation of wireless chargers also harm battery life.😜
Because of additional heat right? If only I'd partnered with a company that include tech to limit the heat created while wirelessly charging... 😉
All batteries work this way. And wireless charging is a solution in search of a problem. How is plugging in a cable any less tedious than putting a device on a wireless charger? And I’ve had batteries swell in devices that were unused and in storage. It’s better to keep your battery charged on a somewhat regular basis.
Mine is still at 100 % and it's a iPhone 15 Pro Max. One of the reasons my percentage is still high is because I maximize the capacity of my battery.
I set my phone to charge to 90%. After the latest update, I noticed the phone charged to 100%. Opened the battery in settings, and the setting had not changed. I set it to 95%, then brought it back to 90%. It seems to work now, but I found it curious that this happened. I have an I-phone 15 pro, running 18.0.1.
The iPhone does this every once in a while to keep track of the batterie‘s health state.
I invested €1800 in an iPhone 15 pro max direct from Apple on release date. After 9 months my battery max capacity was only 89%. My iPhone 13 Pro Max was at 92% after 2 years. My battery only lasts 10hrs whereas my 13 I was getting 16hrs with same use and charging styles. Very disappointed. Apple say phone / battery is fine because I’m a heavy user. Not happy…
Very good THANKS
Great video and thank you.
Great information. Thank you.

I got a used iPhone 15 around 5 days ago at 92% battery level with less than 300 cycle count, in those 5 days with only added barely around 3 more cycles (I know what a cycle is) it's already at 91% even though I keep the phone at 85% maximum charge and don't overheat it. Is that bad?
These are the little intricacies that piss me off, androids have had this battery limit settings for years but with iOS they only gave the iPhone 15 and 16 these battery charging limit privileges despite older iPhone using the same iOS updates it's ridiculous
I wouldn’t know about claims but I wonder wether using a slower or faster charger negatively affects the battery or not ok the long run.
I recently upgraded from an iPhone 10 to an iPhone 15 pro. The main reasons being that I was running out of storage but the main reason was battert life; it just died very quickly, to the point that the phone was unusable.
I had all the usual battery saving settings engaged: location services off in almost apps, background refresh off for almost all apps, auto-lock set at one minute etc etc. but battery life was still terrible.
Having got my new iPhone 15 I wiped the iPhone 10 and set it up as a new phone (I use it for another SIM contract) and now the battery is great.
Settings shows:
- Max capcity 85%
- Peak Performance Capacity
Very odd and I was wondering if anybody else has experienced this unexplained battery useaged?
Thx
The new iOS does ruin battery life! Facts
Absolute bo..ocks.
What about only using a 5w Apple charger? Lowest heat.
Yes 5w charging produces very little heat it will end up increasing the cycles you get out of your battery
What about to restart the Iphone regulary eg once per week ?
Thanks!
1 thing to add to point one all batteries are made in different factories. My iPhone Pro 15 Pro Max battery health dropped to 99% with 25 cycles. On my new iPhone 16 Pro has a higher battery health 120% iOS will only display 100%
Losing a full percentage after 25 cycles seems especially bad to me. Did it hold up a bit better in the long run?
Very useful. Thanks
Does this information also hold true for iPads?
Ipads have batteries , so yes!
I am constantly charging my iPhone on my wireless phone holder in my car while I am driving. I need to charge it because the Waze app is runing and draining the battery.
Any amount of wireless charging will harm your battery in the long run. Using a wireless charger with a fan, like the one in the sponsor spot, might help a little, but that would be like pointing a fan at your stove so your food wouldn’t burn while you’re cooking. The safest way to charge your battery is with a cable, not wirelessly.
I have 15PM and 75 cycles and 98% health. Doesn’t bother me. I rarely let my phone get below 50%. Have had phone 5 months.
Force quitting apps... I just wish I could get out of the habit, but I close apps without even thinking about it.
Interesting, thanks for sharing ❤❤🎉🎉
I charge overnight. And charge to 100%
I don’t see the cycle count in my battery health screen, running ios18 on my iPhone 14 Pro.
I close every app after I’ve used it and always have done and always will do
Why? It as been reported that you use more battery by opening the apps more closing them and opening them more often
@@MystifyMe97 my battery life always been great and I’m having best battery life on a iPhone I’ve ever had with my 16 pro max and I’ve had all the pro max phones from 11 pro max so it’s working well for me bro
Wasting your time and effort. Old wife's tale.
Maybe, but here is an example, lets say: over weeks or even month you open 50 to 100 different apps on your phone, surely that will consume way more power than just opening few new apps on a given day.
