The battery saver percentage threshold setting on my Pixel 8 Pro resets itself to the default 20% on every reboot.

Steps to reproduce:

  1. Open the battery saver schedule setting (Settings > Battery > Battery Saver > Set a schedule)
  2. Set the percentage value to 15% (anything other than 20%)
  3. Reboot the phone

Expected result: The percentage is still set to 15%.
Actual result: The percentage is reset to 20%

2 months later

Seems to be fixed with the most recent update.

    aha this was likely an upstream issue that was fixed in Android 15.

    Same problem here, after each reboot the percentage is reset to 20%.
