Battery Percentage not displaying properly
So for awhile now my battery percentage has been acting funny. The majority of the time, it displays 0% regardless of the actual charge. Sometimes it will display as the real charge but then it will remain displaying that level even after the charge has dropped. I have tried formatting and flashing different roms, it doesn't seem like the ROM is the issue. Currently using one of the CM11 builds from last week. You can see from my screenshot that regardless of being charged it shows 0% across the board for the last 2 days.
Anyone know what's up with this? My gut is telling me to open up the case and check the battery connection, but I'm wary of cracking my backplate when prying it open. I heard its quite fragile.
