I'm using latest XWLPX firmware and it have been working fine and now suddenly the battery icon keeps flashing, I can't see any battery stats, the battery percentage dont go down and when I reboot my phone it drops from 80% to less than 20%. When the phone is turned off a battery is shown indicating how much battery percentage is left and some seconds later it disappears and it appears again, over and over. Is the battery damaged? I've tried to unplug battery, wipe cache and wiping battery stats. Yesterday I used my phone when it was raining just to see when the bus arrived but I dont think just using it in the rain for a short time will damage it. Shall I try to re-flash in Odin?
