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 4.3.0 adds support for PineTab, developed by nephros! Thank you!

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
  • Pine64 PineTab
  • Sony Xperia 10 / 10 II / 10 III
  • Sony Xperia X / X Compact
  • Sony Xperia XA2 / XA2 Plus / XA2 Ultra
  • Sony Xperia Z3 Compact Tablet

For some devices there's partial support:

  • Sony Xperia 10 V (pausing and resuming charger doesn't yet work)

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

Bug reports and translations are most welcome!

Support for Jolla Tablet is partially in version 4.1.0+, but it's untested as I don't have a device to test with, and no one from the forums hasn't yet tested it either. Can you install the newest version? If not, send me the error messages it gives and I'll build a compatible version.

There's an issue for this in GitHub; any help with testing and making it run on Jolla Table is most appreciated :)

Battery Buddy works fine in my XA2 plus - just one thing is a bit irritating: I replaced the old battery. Now CSD tool shows "good" health. Status in battery buddy is just "ok". Is that a remainder from the old battery?

Battery Buddy only shows the information the system provides to it. I can have a look at if there are multiple places to get the battery health information from. There is a reason the CSD shows different information than Battery Buddy - but what it is and how to fix it, is another thing altogether.

You may have to set the sliders to your preferred values in the settings page, and in the worst case, stop and start the background service again.

Ahoy direc!

Thank you for the battery-buddy app! I installed it in sailfish 3, worked for a while, I updated it and wasn't working anymore (to stop the charge) even I downgraded. Now that I updated to sailfish 4 started working its own again !

I got the temprature in "F", and I noticed that there wasn't any option in settings page. In the source code I saw that it checks the locale, which is set by choosing the language. From English US I choosed English UK and I got temprature in "C" !

When you updated to SFOS 4, it pulled the newest version from OpenRepos, if you had the repo installed. That's the most likely explanation.

2021/08/3 - After new install of SFOS-4.1on my xperia10 Plus Double Sim,harbour-batterybuddy-3.15-1.armv7hl does not start from screen/interactively (starting icon/w. rotating arrow appears for some seconds, then disappears).- starting from terminal with:/usr/bin/harbour-batterybuddy &works ok.I tried installing both interactively and also by CLI, with:sudo pkcon install-local  /home/defaultuser/Downloads/harbour-batterybuddy-3.15-1.armv7hl.rpmI tried the same with 3.14 and 3.13, with the same result.Is my first post here, so I apologize in case this is the wrong place for it.Comment on 2021-09-07 Meanwhile the problem "automagically" disappeared, both on Xperia (sfos-4.1) and on Jolla1 (sfos-3.3). Well done, thanks!

Hi, would it be easy to add an option to disable charging if battery temperature overshoots a certain threshold and restart charging after it falls back? My battery often gets very hot that I have to temporarily stop charging for a while to have the temperature settled.

I pushed the vew version yesterday, and I can now confirm that the current timer method works as expected!

 

Please report any issues you may encounter, and don't forget to update the intervals after update!

Just a quick update!

I finally got around this again, and managed to get libkeepalive signals working within Battery Buddy service. The big update is quite close now, so that that 1) the CPU should get some sleep, and 2) the service should receive a kick from the OS side periodically. Still a lot of actual implementation to do, and GUI needs to be updated, too, because custom intervals are now gone. Oh well, I'll take it!

I just noticed that the CPU doesn't enter sleep mode at all while the device is plugged in to a charger. That is the reason the app has worked seemingly fine this far - preventing 100% charge.

 

I will still update the timer code to survive CPU sleep mode, it's a good exercise :)

Can confirm on X10 (not two) that cpu sleep according to sysmon is 0 when the daemon is active. Stopping it lets the cpu sleep again.
I do not see particularly high CPU usage either way though.

I noticed the same behavior; CPU doesn't enter sleep at all when the service with keepalive-tool is running. I'll revert the change and start implementing the non-workaround method. It may take some time, though...

I have killed the harbour-batterybuddy-daemon (child process of keepalive-tool) and started it again without the tool. Since then CPU sleep is high again and battery usage is low, hooray.
