Given that I use a lot of knock-off Chinese batteries and have tweaked a lot of things, I thought the wildly inaccurate battery readings I was getting on my Atrix probably wouldn’t get fixed. Rebooting was a temporary fix, and I’d often get back 60-80% battery by restarting after going down to 15% in just a few hours, only to have to reboot again. xda-developers, as always, to the rescue. Completely fixed my problem, all hail open source and the community. Motorola Atrix battery level fix.
