When my battery hits 10%, I get a low battery notification, but immediately afterwards I get another one (even though it's still at 10%) (and then another one for power saving mode turning on, but that's expected). Anyone know how to solve this?

I noticed the same.

Oh, I thought I just messed with some system file. Maybe it's actually a bug, then.

I also have seen this behaviour always thought it is because of 10% and then 9% but last time I checked it happened so fast there was no time for the percentage to go lower. So I also think this might be a "bug".

The charge status of the battery can only be estimated by the phone based on the voltage. but this is not completely accurate: the voltage varies based on the load. So it's perfectly possible that the 10% threshold is crossed twice within short time. Example: the voltage goes below threshhold, your get the notification, power saving mode kicks in which reduces load on battery, voltage increases (just enough to go over the 10% threshhold) and shortly after that decreases to said threshhold again, triggering the second notification.

Only way to reduce this effect i can think of would be to increase the hysteresis for switching threshhold.

I have noticed this too, but it doesn't bother me.
