Thank you for sharing your expertise.

It seems to be unbelievable that none of this has become part of AOSP.

I should have a battery setting that optimizes either for battery longevity, or for maximum power delivery. These settings should incorporate best practice, such as you have outlined.

The last stable ACC release was in late 2023, and it appears to remain the best battery management tool for longevity.

Why is this so?

I rewrote your script slightly, and ran it on my Pixel 3.

  find /sys/devices/platform |
  grep battery/uevent$ |
  head -1 |
  xargs grep NOW

  POWER_SUPPLY_VOLTAGE_NOW=3955800
  POWER_SUPPLY_CURRENT_NOW=-222656
Also:

  find /sys/devices/platform -name uevent |
  grep battery |
  head -1 |
  xargs grep NOW


  find /sys/devices/platform \
    -path '*/battery/*' \
    -name uevent |
  head -1 |
  xargs grep NOW

Newer Pixels have a concept of "bed time" and charge slower overnight, for battery health.


This is also present in my 4a, perhaps it's a feature of Android 13.
