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
I never really cared about the limits etc. I charge every night to 100% and after three years I can’t really see a major difference in my battery life. I see the battery saving stuff as a hassle and extra stress. I just keep out of it completely. If some noticable negative effects would appear I would start utilizing the 85% stuff etc.
Honestly at this point it all feels like overkill.
exynos?
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.
The battery health is at 100%
seems like you have your answer
If you open an app that shows amps going into the phone or put an amp meter between the power adapter and the phone to see what amps the phone is drawing as it charges. When the battery reaches 100% you can see that no power is going into the battery so it is not going to be damaged by being overcharged or by being held at 100% for an age.
So your charging strategy is good and way better than the people who charge to 85% and then moan about battery life.
All batteries deteriorate over time. This deterioration is faster for batteries that are charged above 85%. However, it is your phone and obviously you should use it how you need it. If you actually need 100% then that’s just how it will be.
Overnight charging can pose more of a fire hazard sometimes, so it’s best to charge up before you sleep and then top up in the morning perhaps.
Bad idea. You lose but a couple of percentage over night, and topping it up in the morning, let’s say 6% charge, is far worse for the battery then just leaving it be
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.
Does the battery deteriorate even if I take it off charge as soon as it hits 100%?
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%
