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.
New! Version 4.2.0 adds support for setting maximum charge current for selected devices.
New! Version 4.1.0 adds initial support for Jolla Tablet.
Important: Sailjail support is enabled in Battery Buddy 4.0.0-1, which means it requires at least Sailfish OS 4.3 to work properly. For Sailfish OS 3.3 and up you should be able to use Battery Buddy 3.17-1. For older versions Battery Buddy 3.15-1 should work fine. For Sailfish OS 2.2 you have to download the legacy build.
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
- Fairphone 2
- Jolla Phone
- Sony Xperia 10 / 10 II / 10 III
- Sony Xperia X / X Compact
- Sony Xperia XA2 / XA2 Plus / 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!

Why is it not possible to charge the battery up to 100% with automatic charging control? That stops at 95%.

Thanks for feedback! That's just an arbitrary maximum value I chose. I have to revisit the sliders, too, because it's quite hard to get the value exactly right on Jolla Phone with its small display. I'll fix both of these in a future release.

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

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