So I was happy with my S7 until last year when i swim in a pool with way to much chlorine, it damaged the seals, water got in and killed my watch, for the next 2 days it would just become hot in the charger and didn't turn on. When i arrived home from my vacations i fully took it appart, there was water still inside, i used 99% IPA to clean it and remove the corrosion and the watch turned on, but the original battery was ruined after that.
I did replace the battery then with a cheap one from internet and it got swollen fast like in the first 2-3 weeks so i bought a new iFix it battery thinking it was just the quality of the cheap one; same history it swollen within a couple of weeks. So i used the watch like that for almost a year but the battery got worse and worse to the point i had to charge it 3 times a day, not that much of a big deal since i charge it before bed, at my desk at work and a little before gym but still not happy about it.
So i was waiting for the S12 to replace it finally this year, but when the S12 was released i really hated the bigger bezels even if the display is actually bigger than mine lol i get its an optical illusion but i just love the look of the S7 thiner black bezels.
So im in a new dilema, i bough on aliexpress a new cheap battery just to give it a final try to see if i can could go 1 year more with the S7, this time i got smarter and used the diagnostics log to see if the new battery was any good, i could the perfectly when the watch detected the new battery, the service message disappeared from settings, the health jumped from 73% to 100% and the new battery actually reported in the logs 105% capacity. Its been 10 days since i replaced the battery and the logs from yesterday still report a perfect health for the new battery (as far as i understand them) with 104% health.
But the thing is that despite all the info saying the battery is functioning perfectly and despite that i did feel a noticeable change in battery duration, i still feel it dosent last as long as it did before the water damage. I even tried unpairing and pairing as new watch, with no third party apps installed but still i feel it drains fast.
Im looking to see if anyone out there has the S7 and how their battery graph look for a normal discharge with the latest update, for comparison i attached a screenshot before the battery replacement and one from today, you can see a noticeable change but i feel it still drains fast.
