Battery Buddy

Fully discharging a battery and charging it back to full charge again wears it out sooner than you might expect. Battery Buddy can help you increase the battery lifetime by automatically pausing and resuming charging. You can set alerts for low and full enough charge levels, too.

Important: Battery Buddy 3.6-1 and later releases require SailfishOS 3.3. The legacy version that supports SailfishOS 2.2.0.29 and later can be downloaded manually from GitHub releases page.

The application comes with a service component that takes care of charger control and alerts. This means that the application doesn't have to be opened for alerts and limits to work - which is against Jolla Store policy, and hence worth mentioning here. You can control the service from the application (start/stop and enable/disable on boot).

There is now a logging option, which can be accessed via the Settings page pulley menu, with three logging options. You can copy the log contents, too, so submitting the service log for debugging purposes is now a lot more convenient! Using --verbose and --debug flags still work as before.

Please note that the charger control mechanism may not work for every device out there. So far it has been successfully tested with the following devices:

  • F(x)tec Pro¹
  • Jolla Phone
  • Sony Xperia 10
  • Sony Xperia X
  • Sony Xperia X Compact
  • Sony Xperia XA2
  • Sony Xperia XA2 Ultra
  • Sony Xperia Z3 Compact Tablet

Please let me know if it works for your device, or if it doesn't work!

Bug reports and translations are most welcome!

Automatic turn off did work too

Good to hear!

If manual part works, the automated part works too - as long as the logic behind works. So far so good :)

At least manual part does work on X10 . Great !!

Confirmed. This is great (and came out just as I was in the process of trying to get X10 support into battery notifier).

Great! I'll add it to the list in the next update!
