Battery Buddy is an utility to monitor and control your Sailfish OS devices’ battery level and charging percentage. It lets you set a maximum (e.g. 85%) percentage when the charging stops, and a minimum (e.g. 75%) when it continues again. It can also alert you when the charge is getting low (e.g. 30%) and tell you details about your battery (condition, temperature etc.)
Battery Buddy has been reported to work 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
You can install Battery Buddy using Storeman, or downloaded directly from Openrepos.net.
If something doesn’t work, there’s an unlisted device it works with, or there’s an unlisted device it doesn’t work with, drop in a message so we can fix it!
Thanks!

Update Swedish translation (thanks, eson57) (4.1.1)
If you are feeling adventurous, and don’t mind possibly having to revert to previous version, there’s now a 4.1.0 beta version available. It contains two major changes:
Initial Jolla Tablet support (untested, as I don’t have the device)
Changed logic for searching and selecting the correct /sys/class/power_supply/* files (WorksForMe™ with Sony Xperia 10 III)
It also now logs the momentary power consumption of the device.
Works fine on the 10 III. No problems so far. According to the logs, the 10 III goes as low as 32 mAh when sleeping, but even then there are frequent spikes to 200-300 mAh or (rarely) even 700 mAh. And that with almost everything disabled, actually only WiFi remaining active.
I’m getting similar readings; sometimes it’s almost down to 30mA, but every now and then it jumps to three digits - which is part of normal activity, I think (checking email happened to be running at the same time, or WhatsApp was synchronizing something etc.)
I’ve had email sync set to “Always up to date”. Let’s see if changing it to say every 5 minutes makes any difference. Other than that, the readings were taken when Android support was disabled so absolutely nothing was running on the Android side, and actually the very same on the SFOS side, i.e. Battery Buddy being the only application that has a background service, and nothing else running. Location, Bluetooth, mobile data disabled, only WiFi active.
Hi direc85, thanks for improving this app. I installed the 4.1.0 beta and logged. After that I disabled everything (except: don’t disturb is enabled) on my Xperia 10 III and switched off the display for the measurement.
I’m interested, if your power consumption on your Xperia III is similar.
(Sorry, I can’t upload a .txt-file, so I had to took screenshots.)
@Speedy-10 You should actually be quite satisfied with the power consumption of your 10 III. Your logs show 1% drop every ~1,5 hours, In my case it is 2% per hour.
EDIT: Today it is slightly better, it was almost exactly 1% per hour on 4 consecutive hours. This is a new device, so maybe the battery is yet to obtain its full capacity, which usually takes a few full charging cycles. We shall see.
What was enabled on your phone when you were taking those measurements? Phone, mobile data, WiFi, Bluetooth, location. etc?
@fingus, this negative vs. positive current is not application version dependent but device dependent. It is how the devices themselves report it. Older models (e.g. XA2) show positive for discharching and negative for charging whereas the 10 III reports it in a reverse way.
@direc85 If I may a small feature request, would it be possible in the log screen to display battery percentage in a slightly different color than the rest? This would allow to easily see how/when the battery level was dropping. Now it is quite difficult to find it among the other data. Thank you!
