Battery life level app

Using /e/OS Applications

Hi,
I’d like to know how used is the battery of my smartphone as its autonomy is decreasing…
In parameters menu I didn’t what I want.
Is there an entry for that ?

So may be I should install a third-party-apps ? In that case, which one I should consider ?

An IA chatBot suggested me :

  • AccuBattery (but I do not really like the trackers and permissions required)
  • an ADB command… why not is-it reliable ?

Is there any topic or wiki about ? (I used the search bar without success).

It is easy to get too much battery information and to know what is useful, I was going to say about adb using dumpsys. However this is a recent post which at least contains pointers to some of the things worth learning, I think. How to Check Battery Health and Status via ADB (Android) - Technastic.

Thank you,
your article seems great.

I notice this command in Termux !
```
cat /sys/class/power_supply/battery/charge_full
```

It requires to load the battery at 100% and to compare to the theorical value. I’ll try it tonight. (Or with adb)

I have tried the following apps in the past:

  • iFixit Android app: contains some trackers, but probably worth a look
  • BatteryGuru: contains some trackers; probably the most interesting app because it tries to determine the battery state over several charging cycles
  • Plus Plus Battery: Open source app on F-Droid; I have only tried it once, but I am not sure whether I got an accurate result back then. As its development has not stopped (and it is open source), I would suggest that you try it (I will again).

EDIT: First new impression of Plus Plus Battery: You have to correctly configure the multiplier for the consumed energy. Then, it seems to be quite close to the measurement of BatteryGuru for the total capacity - maybe less sophisticated, but I would recommend to try it.
