For anyone who wants the battery information, here is what the battery reads: Logitech is using a Springpower Technology Li-Poly battery that’s rated for 750mAh at 3.7V (2.775Wh). The model number appears to be 383450. The battery measures roughly 50x35, +/-1mm.
i watched the g900 review from the description and i gotta say i'm disapointed, u were mentioning their measurements and talking about tech in the mouse, which is all good and well, except there was no measurements done by gamersnexus in regards to the mouse's precision, for example:
max tracking rate, positive or negative acceleration checks, prediction tests, jitter tests (often existing at laser sensors and at insane useless high dpi sensors), your own latency tests, not going by logitech's data, lift of distance, checking if the mouse works perfectly on all possible mousepads, inlcuding, hard pad, cloth pad and metal pad.
basically i do not know if this mouse is precise from your video and article all i got is your subjective opinion and logitechs results, which we can't trust of course.
please consider changing this for the future, i know mouse reviews aren't gn's specialty, but u certainly can step it up to the benefit of all your viewers.
think about your mouse review like a graphics card review without benchmarks in a way, it's quite useless.
this is positive criticism btw, not hating, but being frustrated with the lag of real reviews of mice on the internet nowadays and i know u can step it up and want to give your viewers and readers the best data to decide on.
cataria pega, I agree with you. I hope GN would eventually get to do the kind of deep reviews into mice like they do with other stuff.
Check Rocket Jump Ninja channel in the mean time, he does a great job with mice.
Those are some seriously unreasonable expectations. I have not seen *any* tech youtuber test on those things specifically. I know a lot of people have a somewhat higher expectation of GN compared to others, but GN doesn't have the equipment for that shit mate.
I think t's fair to expect that kind of content from GN based on their GPU and other content, but it's true, it's not easy to go deep on different areas at once.
No independent tests have been done on Logitechs claims over the G900 wireless performance(other than subjective "I don't feel a difference" stuff), which is a shame. Hope someone eventually does it.
rocket jump ninja does not do objective tests of the mice, but "if it works for me in quake, it should be precise and work for u" kinda thing, he doesn't do max tracking rate checking and all tests are done through his hands, i mean it is enough to point out dirt like the razer lancehead wireless, it's still far from great imo.
if we would do graphics card tests without benchmarks, people would lose their minds about it, but for mice it is ok apparently, and for computer displays too btw, almost no one does latency testing on displays....
btw ramla777 a small youtube channel at 600 subscribers does max tracking rate checks at the dpi settings the mice have, i don't know what testing he uses, but at least he does it.
don't get me wrong rocket jump ninja is far far better than most of the rest of "reviews" out there, but it's not enough to do an objective decision on.
i can look at a gamersnexus graphics card review and i will know pretty much exactly what i got: sound level, temps, normalized temps/soundlevel, performance overclocking head room undervolting and very important vrm quality and efficiency!... everything i need to know and more.
steve even said in past videos, that he doesn't review psus for example, because of the knowledge and tech needed to do it properly, like johnyguru does for example, but that kind of knowledge or tech is not needed to make a mouse review much much better.
and keep in mind gn is paying buildzoid to give us the only real vrm reviews of graphics cards and motherboards out there (not including buildzoids own stuff).
so we know gn is doing their best to give us the best reviews they can and maybe they will read this and actually improve their mouse testing, because i know they actually care.
Logitech rep: "Steve, when are you going to send the review unit back? There's a line of people waiting to test it"
Okay mate I would send it.. Just glue it together.. ( ͡° ͜ʖ ͡°) did just a lil teardown

I did a mouse teardown last night after I lost my 8th PUBG match in a row. No idea why it takes long hair Steve 25 minutes, took me like 5 seconds :)
Hardware Unboxed LMAO
i think you should do benchmarks instead getting your rage out on the poor mouse, it seems like a great therapy for you :)
Seems to me short hair Steve just needs to relax after playing PUBG, haha.
and you shoooould consider anger management.. becomes cheaper in the long run if you're thinking of tearing down more "mice" also keyboards perhaps?
Maybe due to you being fuelled still by rage so it might not go together as well :-p
I like to imagine your Logitech contact watching, with similar reaction as a mother watching a lion maul her child.
Thanks for the full tear down, not many reviewers do this
17:02 that moment when they skip the Torx screw and you don't realize it so you proceed with the teardown only to realize your lack of a Torx screwdriver ruins everything
the pursuit of knowledge is always worth it. even if you break some eggs.
FYI - the metal pin rides on ridges on the inner diameter of the scroll wheel under spring tension, which can be relieved to allow for free wheeling - it's not sticking into the spokes (that would completely block it's rotation).
Good Video. These tear-down videos are always interesting and informative. I have always been into how things work.
Any conductor that conducts current generates an EM field so that is a coil on the outside. Also the mouse would charge faster if it moves around the coil as more tension is inducted in the wires when the magnetic field is changing or you have an object moving through the magnetic field
Thanks for the tear down. Especially of the mouse, interesting to see how the scroll wheel switch mechanism works.
Thank you for making this video.
I couldn't find any information about the battery of the G903 somewhere else.
Extremely well-informed video as always, you do good for the Gaming Community 💪
A million thank yous! I was about to "fix" my "broken" mouse wheel. Just got this mouse new and thought it was busted. You saved my mouse slides!
You guys never knew you were able to travel into the future but let me tell you today is October 12th 2021 and you have helped me fix my g903 mouse. I was able to take it apart and replace the right click and left click which were giving me double click issues. Thank you guys very much
Biggest flaw in g502/g903 that no one mentions about is cheap membrane button under the wheel (middle click) which wears out in a year if used frequently. I enjoyed using my g502 and absolutely love the scroll wheel, however g502 was marketed as full omron switch device and it's shame they omitted using a proper switch for middle click button.
Thanks for the information. Hope you get a new mouse soon.
Enjoyed this it is good to see how these things work keep it up
This is why I watch you. I save tons because you tear down what I want to tear down. Thanks
the tiny spokes in the mousewheel is for the tachometer that shines a light/laser through it, and "sees" when you rotate the wheel and translates that to the scroll function :)
Excellent tear down i am looking to get that very setup G903 and powerplay. 👍
Thanks for the teardown. apparently newegg and amazon sell the battery for this mouse. the number I used to track it down was 533-000130 next to where it says M/N on the top right.
Thanks for the number. Good that you can get a replacement.
Just in case this has not been answered yet:
In regards to Steve asking about what the coil is referring to,
The green flex PCB with the large copper traces will be the resonant coil in this application.
A coil is just any conductor that forms a loop.
You can make an inductor out of power extension cables when you wind them up for storage.
Hope this helps.
Side note: In circuits capacitors and inductors dont actually have to be physical components soldered to the PCB. They can be made out of specialized designs and patterns in the copper on PCBs. This technique is quite often used at higher frequencies like in RF (eg 2.4GHz) etc.
(I have an EE background in design and manufacture of consumer electronics)
Teardowns are my Fav, Thank you Steve
Hey Steve, it's most likely similar to an RF antenna design; this would be tweaked to cause resonance on the coil inside the mouse.
Owned a G903 - RMB fails / stutters after a few months, the tear down is not that clear on where the location is of screws - please pause / indicate next time.
Great timing, just bought this mouse a few days ago : p
Have fun with it.
So how long did it take until you got the double click issue?
Hello Steve,
I would like to know how thick the charging base portion of the powerplay mat is.
I am using one of those large extended mouse pad, so I am wondering if the thickness of the charging base is thin enough to just place it under my existing pad without feeling too much of a bump?
Please let me know. Thank you.
arent the spokes used with an optical encoder to measure mouse wheel rotation, the engaging of the clickiness happens here 21:34 on the inside of the wheel
For accessing the copper coiling inside the mat itself, did the idea of dissolving the inside of the mat in something like acetone leaving only the copper remaining come to mind? I'm no scientist or anything but with my basic knowledge of chemistry (and I mean very basic) that idea immediately popped into my mind and I was hoping you'd do it.
When you finally pulled the rubber off it was SO satisfying.
That's what SHE said
I bought my Powerplay on 12. 8. 2019, so 4 years exactly (+few days) and it was used. Still going strong! Just upgraded from G903 to G Pro X Superlight around the time the mouse came out.
I am glad Logitech still supports it as it's a great tech and I bet they patented the snot out of it as I didn't see this implementation from other brand (only a corner of it from Asus or somebody).
But as I didn't see any marketing push or big mentions about Powerplay in their trailers... I worry that they will drop it sooner or later.
Only negative I have is that the cloth top is nowhere to be found for me. The support told me that I bought the right one - the G240 - but you will find out that G240 is soft cloth without hard back. So it will warp and stretch like a carpet from a chasing sequence in a cartoons.
RGB, charging and the reliability is still awesome and charges to 80-85%, so the battery is not being kept at 100% all the time. I never had like an issue with the charging stopping to work or something. It's so great in fact that I made a fool of myself when wireless mice was brought up in a conversation and I was defending it without realizing that only Logitech offers the experience that I was talking about. (fyi - I have nothing against wired mice)
And all the G900/903 and potentially all the rest of their latest 'G' mice are all defective in their switches.. and half of them are defective in their scroll wheels.
Spent $450 + an RMA on these top of the line mice (4 total used), all have had either faulty scroll wheels or the "double click" issue, or both. The longer time goes on, the worse it gets.
The only resolution to the switch issue is to replace them outright, with real japanese omron switches and not whatever the garbage they're using is; so people say anyway.
Wtf used it for almost a year now it's just perfect
iunno, I mean I guess it depends. for me, Corsair M65s broke on me several times, and we have like 5+ Steelseries broken in the household. the build quality, switches, etc, they are all just awful. but, luckily, since the shop gives you warranty, there is practically a 0$ cost of replacement so I don't mind.
I've had my G903 for around 2 years and it's flawless. No scroll wheel issues, no double click issues, or any other switch issues. Sounds like perhaps you just keep breaking your mice by ham-handing.
@@SOSOGUDRANA Same, haven't had an issue with my 903, build quality is top notch, and the buttons are also great. The shape can be improved however.
Awesome teardown! I have used Logitech mice since the stone age. Every time I buy one with the "hyper scrolling" feature, the middle mouse (mouse wheel) click loses gets mushy/unresponsive after about a year of use. The hyper scrolling works forever, and the toggle stays functional, but they middle click dies super easy. Any idea why? Happened on my G700 and my MX Revolution consistently.
My G700S is working perfectly since 1 year and a half for now
From what Iearned in Electromagnetics class, here is my assumption. That outside ring is the inductor that is powered by the usb 5V 2A supply. The inner inductor is magnetically coupled with the outside one and works like a transformer. The output of the inner loop is probably lower voltage but significantly higher current, which allows the generally efficient wireless charging.
I've been using A4 tech NB- series of wireless & battery less mice for the last 10-15 years. friggin' love em. no cables getting stuck on stuff, no batteries weighing it down. (and running out). just works.
It uses a similar design to power it, one of the models even had enough power for an extra LED inside of it. (just felt like testing it, and hey,, it worked).
My biggest problem with them though, has been trying to find a new one, once the buttons wear out. Not all that common here in europe.
this logitech model might just be my next mouse, if it's any good.
What if your g903 stops charging? I can use it when plugged in, and of I plug it in but have it turned off it looks like it's charging (the 3 lights fill and empty, indicating charging mode), but when you unplug it, it just stops working.
Will tearing it apart be worth it? Will it work with the powerplay mat with the battery not charging like this?
Thanks. Woulda been interested in how the wheel encoder works. Does not look like the encoder is on the shaft, but maybe related to the spokes on the wheel?
After 6 mos use I started to have a double click issue. There are no fixes on YT at the moment.
Same, why im sending my mouse back for repairs or replacement.
interesting the 2.8 watt-hour capacity of battery exactly matches the Sanyo Eneloop XX that i have in my current Logitech mouse even though it's a Lithium Pouch versus Ni-Mh Cylindrical AA battery ... so they switched from 1.2 volt to 3.7 volt but kept the watt-hour the same ...
On the list of stuff I would not get for myself, but something a friend or family member would appreciate
its just cool to see *whats underneath*
as an AvE sub, i really enjoy the different teardowns. thanks GN. :)
Keep yer stick on the ice.
but will it chooch?
Also: "Don't turn it on, take it apaaht."
Question is, can you load the mouse with a normal inductor or does it only work with the logitech one.
Anyone else having double click issues with that mouse?
Yep
yea that's an issue with this mouse. I ended up tearing down a 9 dollar logitech mouse and soldering those switches on to my g903
Yeah just don't buy this mouse to whoever read this don't terrible clickers. 2nd replacement same issue. Going for the third replacement I am turned off logi mouses for now. I will try to ask for another model cause obviously this one had terrible quality control.
@@mybigfatfrog7975 its not the QC. its that they are putting switches which are not spec'd for the low voltage and current these new mice SOCs use through the switches. if you hit up amazon and grab d2f-01f-t switches. those are actually rated much closer to the electrical spec these new mice SOCs use. its going to become an industry wide problem if they dont change up their engineering as more and more SOCs are getting lower powered. I imagine with the Hero version being way more efficient the issue appears much faster as the Hero version doesnt sport a larger battery. full explanation here th-cam.com/video/v5BhECVlKJA/w-d-xo.html
@@xelnaga18 Not a technician man.I prefer to rma them every time I am at my 3rd rma as we speak. so It hopefully will last another year and then probably not gonna get another mouse from Logitech. Even though they have excellent support not gonna lie. Every peripheral I have is a logi. But I lost faith with this model.
I think on base only is copper wire ,power delivery, which design to resonance with receiver one on mouse which I believe is the important one. you might neeed to crack that module to see what is wireless charging specification.
I'm really having trouble pulling the top and bottom apart. I've removed all the screws and tried using a pry-tool around the sides, but it feels like something is left in place. You didn't show the top screw being removed, did you miss off anything else before pulling it apart? Thanks
So if you put the induction adapter into the G903, you can't change the weights anymore, correct?
Small correction at 21:25. The spokes you see are not for engaging the detent which gives you haptic click as you roll the scroll wheel. Those spokes are the relative encoder that helps to count the rotation. The detent clicks you feel are because of a spring that engages the inside of the scroll wheel at 21:31. They are not very prominent and looks zigzaggy! on the inside rim of the scroll wheel. Think of it like a mechanism from a ratcheting spanner. Sample principle.
I unscrewed 5 pieces but it still won't open can you help me please is there more screws I didn't notice
This video is gem......save me a lot of time...Thank you Steve. Wish I could give it a thousand likes.
my scroll's side-click switches started to do occasional double clicks for the last 2 years, which switch should I use for the replacement?
If you take the puck and solder the contact points to any other wireless mouse with similar contact point on the bottom would the mat charge the mouse?
Would the mousepad work upside down? I am creating a minimalistic desk and and would embed the mousepad into the desk. Naturally, I would want the notch bump to face down to keep the desk surface flat. Any insight?
what about dissolving the outer from the power pad using Acetone or some other solvent.
the puck color on the background make me crazy
Hey @Gamers Nexus do you know how to fix the double click issue with this?
Logitech exec: "Who the hell came up with the idea to send Steve of Gamers Nexus a sample, haven't we learned from Linus?!" LOL!
What about magnetic fields intersecting with your body over long time?
Minus the annoying Teflon feet, they should make the mice able to be disassembled.
The reason is that you do need to get in there to clean it every now and then.
I have a Logitech MX310 and I am seriously considering going on a buying spree to have spares because this one is very easy to take down and clean when required.
Especially as dust tends to accumulate in the scroll wheel that is optical based and thus make it stop scrolling efficiently.
A quick disassemble, cleaning of the wheel and you are good to go.
As for the pad, I am a bit bummered, I wish there would be more screws rather than glue, as glue over time has a sad tendency to let go.
Doesn't the 903 have a screwed up mouse wheel button or not have a mouse wheel button at all? I understand it's very different as far as the button layout and scroll wheel assembly goes, or at least the functionality...
Nice video, but what is inside the charging core ?
Is it possible to mod the logitech mouse to use Qi chargers? Would like to see a video on that if possible.
Question: is the charger flat? Those wires inside seem like they are an issue. I play osu! with mouse so minute stuff like that would be a deal breaker
What rating were those micro switches? Are they using omron 20m 20m or 50m?
Would have been really nice if you pulled it apart a bit more. I am trying to replace the switches because the G903 is plagued with double click issues due to the crappy omron switches.
Didn't know it was this easy to disassemble, can't wait to get my g900 working now.
Edit: to add, I think I can just drill a hole through the feet to preserve em, hope it works
my scroll mode is for some reason stopped working and i dont want to destroy my mouse. Is there anyway I can fix it without taking it apart
i have 2 of the 903 mouse.. love them.. and the charging mat.. sure glad you made the video.. no way would I be tearing mine down lol
Just thinking if you have another power interface mat why not try and read the RFID tags in Library books by setting a book on top of the power mat.
Anyone know what kind of cable is used to connect the RGB header(the black part with the lighted Logitech logo) to the PCB that's inside the mousepad itself? Mine broke and I'm wondering if there's a way to replace it.
What is the rubber in the bottom of the mouse called i need to buy some cause i did a tear down today and they wont stikck back lol
Hopefully Logitech reads these comments. I'd love a G500 wireless mouse. The shape and feel of this mouse is timeless!
The G500 was a great mouse! The G500s was short-lived, but also good.
Awesome video
For my part I was curious to see if we can teardown the mouse without destroying everything, now I know we can
Thank you for this video. I'm planning to put the striped powerplay under another mousepad. Hopefully it is thin enough that I wont feel it during mouse movement.
I'm also considering this, how did it go?
@@Psycownage worked amazing. I have not stripped powerplay for mouse and another generic qi charger for g915. Both under MPC 1200.
I didn't strip the powerplay as no matter how much you strip, you'll feel it under mousepad.
So I cut cavity on the table surface instead; since I'm cutting cavity anyways, I can do it a bit more and not strip the powerplay.
can u charge a g903 with the qi dock charger of bequiet dark base pro 900 ?
How do you get in to replace the micro switches..?
i've started tearing down my gaming mouse after I needed to retension the switches after they go bad(or even change them out to preferred switches)..after that, i just buy a mouse for the upgrade(or to just try them out) but dont really need too. Saves alot of money, instead of buying the exact same mouse just because switches go bad(the most common reason I buy another one)
I've been using this mouse + pad combo for almost 3 years now and I don't have a single complaint with it. ❤
If you can find a good combo deal or if you're willing to give refurbished/open-box options a chance this combo is a great upgrade or gift option for anyone who enjoys quality tech.
(Although if I'm being completely honest the wireless mouse pad absolutely feels like a luxury that's "nice to have" but totally non-essential.)
You can charge the mouse by cable much quicker than you would on the mousepad and the battery life when the mouse isn't being charged at all is still FANTASTIC after 3 years but I also turn off all unnecessary RGB so keep that in mind
But that's just a 2+ year user's anecdotal data for prospective buyers to consider. Steve gives some great technical info here and that's infinitely more interesting/enlightening.
can anyone tell me all the materials used in multiple layers as shown in teardown to create mousepad?
I really appreciate the wireless charging mat, I have been saying it for years. But truth to be told we had a perfectly good solution with the logitech g7, which was swappable batteries. You just kept 1 in the mouse, and 1 in the charger, and just flipped them. It was light weight and it took about 2 seconds to swap, and you always had a charged mouse.... Then everyone stopped doing that tech and went to fixed battery with the ability to plug the cable in, which meant if you forgot to charge you had to use it cabled... which sucks!, so now they "try" to solve that problem with this fancy new expensive tech... Why not just do the swappable batteries?????
i've been saying this for years!! the G7 was the best mouse ever made!! (even for us lefties!)
I wish they would bring back the G7. I would have bought 10 of them if I knew the future of mice.
@Gamers Nexus, while we on the topic of wireless mice, can you test the input delay those have compared to their wired counterparts?
We already have:
th-cam.com/video/ke7EZ2vx9LQ/w-d-xo.html
does anybody know if you can daisy chain those two pads ? do a splice of that cable and put two side by side; increasing charging area
The G903 is the third Logitech mouse I've had to tear down and replace the clickers in due to failure. It's an easy process to actually solder the new Japan-made Omron switch in and toss the China-made switches out, but holy damn this is by far the most complicated mouse I've done this with. It's built in three core levels, and the side buttons cause some major headaches with getting everything back in place.
This is also the first ribbon cable I've torn in quite some time, so def be careful if you go into yours. The ribbon wasn't expensive, but I did have to wait about six weeks for international shipping. Perhaps most tragically, this left me with a trackball and unable to play FPS effectively and now I'm playing WotLK Classic and that's going to be much more expensive than any ribbon cable ever could be, so stay safe out there.
where can you buy the japanese switches?
What kind of screwdriver did you use?
Bought this mouse recently. Thought it was comfortable and I liked how clicky it was. ONLY complaint is the wheel. I guess there's enough space and the wheel is "heavy" enough that you can hear and feel it whenever you're moving the mouse left and right.
Well I had to look it up. Never realized this free scroll mice did this lol.
Well the buttons are more likly to get the doubleklicking syndrom than the battery i used my g903 Lightspeed for 5 months than the buttons broke just randomly klicking and unklick
More mice reviews plz.
you do not have to worry about replacing the battery in this mouse. the switches will die of static electricity within 6 months, look it. it's a big issue on all logitech x03 mice.
G903 user for 3 months, my left click no longer works, my right click spazzes out. I sent a RMA request for my mouse 5 days ago and Logitech has yet to respond to me.
my 602 had a similar issue. the middle click button would stop working after a few months of use. I won't be purchasing another Logitech product after this experience.
My G903 has been heavily used for at least 2 years now and zero issues. Like the other guy above in this thread, you're probably ham-handing the thing
@@LBCAndrew first off, Rude. second, I spent $250 on the damn thing, do you really think that I would be slamming it around? third, I've had 3 Logitech mice in my life, and all 3 of them developed issues within the first 6 months to 1 year. I bought a Steelseries Rival 650, no issues, I bought an Asus laptop and it came with a ROG Gladius II, and it has no issues. Fourth, have you googled what I said yet? It's not a limited to the few issues with that mouse. just google "Logitech g903 switch issue"
logitech when recieving it back: look how they massacred my boy :'(
Still better teardown than "What's Inside". ;)
I want them to start making the G600 again. Maybe upgrade the scroll wheel to their fancy one. But I need a replacement for my trusty oll´ friend soon.
A new gadget to explore for Gamers Nexus. . . HEAT GUN
To add a little more information to steves comment on battery charge. Most batteries take the most abuse at full discharge and max charge.
This is the main issue with lithium batteries and why they end up losing their life span. You don't want to leave a lithium at 100% charge or at/below 20% charge. Both of those degrade battery life. Lithium also doesn't have the "memory" effect issue, that's a nicad issue where you almost have to do 100% to 0% discharges.
I haven't been keeping up with nimh batteries, what is in the g700s and i'd assume they are using the same in these, but from what i read it's the same for the most part to nicad
Should have heated the charging pad with a hairdryer before you started ripping it open. That would've softened up the adhesive and made the whole process that much easier.
I have the G903 and mat as an upgrade from the Gigabyte Avia Osmium and it's amazing. Too bad the wireless charging doesn't work at all and no solution was found.
Lol, a Logitech G903 lasting 4 years. I can barely get one to last a year before double-clicking issues arise
a year? mine has barely lasted 6 months, going to see if I can't send it back and get it fixed or whatever because 150 euro for a mouse that lasts half a year is a scam.
mine lasted 5 months
really huge price different 2$ for failure china omron vs 3$ for original japan!! Logitech LMAO!
@@LokiOdinson its because the Chinese ones are spec'd for a much older SOC operating voltage th-cam.com/video/v5BhECVlKJA/w-d-xo.html
I used the G900 for 5 years and 3 months... (no issues or replacements done, battery life was bad-ish tho after 4+ years, but that makes sense); recently bought a G903 😬
okay didnt expect the have to send it back part. O well too late now
Why doesn't Logitech offer a battery replace for the G903? My battery is dying farily quickly after 1 year of usage.
