Everyday I get to bed I leave the phone charging until 7am. I have a bixby routine which enables the 85% limit and disable it 30min after waking up so the battery isn’t staying at 100% all night.
The battery health is at 100% and the charging cycles count is at 170.
adb shell dumpsys battery(mSavedBatteryAsoc and the 3 first digit of mSavedBatteryUsage)
Device is pretty new and bought it on April. Is a S21 FE
health can’t be 100% after 170 cycles?? What are you talking about? Android doesn’t have a battery health feature anyway, it’s all just an estimate by 3rd party apps, which really suck.
And what you do is pretty good, but just charge to 85% until like 2 hours before you wake up, then turn off battery save for like 20 minutes or so, that should put it close to 100% and it will stop charging for the remaining 1.5h.
I noticed after doing that, my phone is cold in the morning instead of warm.
