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
Of course, I agree. We are talking about for people needing it to be 100% for the day for their very heavy use.
Basically charge to 100% however they like, just not keeping it charged overnight for fire safety and the pressure of trickle charging at 100% for a long period of time.
