I have a problem with my WP 7.8 . The icon for the battery shows a question mark, and when battery is low, a heart. Ok, but I can never see a percentage of the energy left (e.g. 70%). I tried a lot of things, but nothing solved that problem. I am looking for an app to pin to screen at least, but no luck either.
Can I do something about this or should I simply change my phone ?
