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
Yes it will deteriorate faster than just charging to 85% because pushing in the energy between 85%-100% takes a lot of work for a charger. That’s why you might notice your phone charges quickly from 50% to 85% but slows down the charging rate a lot as it reaches 100%.
Still, if you find you need the full 100% battery charge to last a day then it’s worth charging to 100%. If in a day you only use day 40% battery then just charge to 85%.
Alright thank you. I used to think the problem comes from leaving it on charging even when it reaches 100%
