Just get normal watches with only digital face or combinated analog and digital (mostly made by Casio) if you need only day and time and maybe chronograph but it depends on what all you need
I have amazefit verge lite and the most I've got is 72 days on a single charge (30mins to charge). I've had it for about 3 years now and on casual use it still gives about 25-30 day of battery life on a single charge.

This is called Power Reserve Mode on Apple Watches. To turn it on, tap the battery percentage then turn on Power Reserve Mode on watchOS 8. This was partially removed in watchOS 9 but you can still use it by turning the watch off then pressing the Digital Crown.
Okay I see everyone hating but this is actually really smart. There are only select times when I used my Apple Watch and I often forgot about it resulting in a dead battery halfway through the day. This way I could only have the “smart watch” when I really need it.
Sweet mother of Obelisk, Osiris, and Ra, my Galaxy Watch3 can do that as well. • Standard mode according to it, from 100%: a day and a half (1d 12h) • Power Saving Mode: 3d 15h 47m • Watch Only Mode: WELL OVER A MONTH. 41D 11H 11M. But there's a catch: it seems to just turn everything off, running only a variant of the AOD that doesn't stay on. Because it's technically turned off, you can press and hold the power button (or just put it on the charger) to reboot back into normal mode.
Your watch can't access the internet, watch TH-cam, save photos, take and receive calls, send and receive text messages, control music, access Spotify, access Whatsapp, change to custom watch faces, use a calculator, record audio, act as a flashlight, scan your heart rate, check your SpO2, check your blood pressure, track your steps, track calories and other health data, log how much food and drink you're consuming, act as an ECG and EDA scanner, check your body composition, track your sleep, play games, check the temperature of anything around you, track your location with GPS, etc, etc, etc. Nice try.
I still have the gear s3 frontier. It's not slow at all. Works great when I go on a bike ride or do any fitness related things. The only reason I feel to upgrade is that I've had it for awhile. But there's honesty nothing wrong with it.
*Laughs in Garmin Fenix* 21 days doing all the normal smartwatch stuff; 45 days in "expedition mode" where it still takes GPS readings every hour or so, but turns off other radios.
My 5 years old first gen Amazfit bip can last for almost a month on a single charge without a power save mode, if i just dont connect it all the time with phone via Bluetooth. All tracking still works, just no notifications and i can still sync the tracking data to my phone later in few minutes. All this battery backup is because of it less fancy looking e-ink display that is way more readable in sun light than any Amoled display used these days in most smartwatches. I wonder why more smartwatches don't have that. 🤔
So fun fact, you can actually squeeze out nearly 4 full days with always on display if you have a simple watch face enabled. About 3 full days with a more complex watch face. And 2.5 days with tilt to wake and a complex watch face. The more you know
People talking about their battery watches. I go further, automatic watches can literally go forever as long as you keep it in good conditions, and that tech is centuries old
I miss my Sony Xa phone having ULTRA STAMINA mode. It really dialed the smartphone to more of a "DUMB PHONE" with the digital keyboard and such. The battery easily lasted within a week if not slightly longer. Not sure if other brands continue to have such a feature, even if it's for a temporary period for someone at a time. Having a more dialed back, simple layout to switch to was nice to utilize.
My Garmin Fénix 5 has a lifespan of almost 10 days as a smartwatch including my workouts, GPS usage and all sorts of background activities, not to mention that it came out in 2017
Nothing beats citizen eco drive lmao, my watch is like 10+ year old never seen it on anything other than full battery. It charges it self with every kind of light
I will never switch from my garmin instinct. It's currently at 43% which is 12days of regular use and with battery mode 25 days. I think it is 56days at 100% but it also has solar so if you are outside you can probably add 1-2 weeks to that
I have the The amaze fit bip lite that lasts for about 45 days on a single charge and I have most of the amenities such as the step counter, body monitoring and a wallpaper
Coincidence!!! Me And My Dad Were Looking At our Watch Collection We Come to A Casio Digital Watch which is still alive After 10+years And Now I Am Seeing this Short!
i have a xiaomi watch and ive been using it for like 4 years now, no complains. It measures my heart rate every 5 minutes and still lasts for a month or more🙏 Worked with my old samsung, and works with my iphone too! it was around a 100$ when i bought it 3-4 years ago. best purchase of my life
Its pretty great feature to have, like when you know you don't need the features to be used for a day or 2 and it would be nice to save the battery Then turn on that mode & after 2 days turn it off and have a high battery device ready to last for another 2 days which it would have normally lasted.
This has the same energy of “The Apple Watch can be submerged up to 100 meters but you probably shouldn’t take it down that far” Then that technically shouldn’t be listed as a feature. Same thing with this power saving mode. Yes it technically can but the fact it takes away everything that makes it smart means it’s not a galaxy watch anymore just a watch. I feel like anyone who uses this a lot just wasted their money on the galaxy watch to begin with
I have a watch that tells the time and the date and I never had to charge it or replace the battery. It's a mechanical watch that you wind and winds by itself when you wear it. It's crazy tech that came out hundreds of years ago.
I have the Huawei Watch GT2 and I rarely use it. When I do wanna use it, I make sure to charge it. Whenever I don't wanna use it, I either choose to leave it charged 24/7 or just leave it on the desk. Sometimes I leave it on the desk for weeks and the battery would barely go down to 50%.
Apple Watch can do the same thing, and even does that automatically when it needs to be charged. The one thing I hate about both of them is that there is a pretty big delay between the button press and the time showing up.
On my older samsung phones we used to have a mode similar to that where we had access to limited apps and even the screen turned b&w. It neeeever lasted as long as it said it would.
My amazefit bip lite lasts about 45 days on a single charge with most of the amenities such as body monitoring,steps counter,wallpapers and a always on display
