Yesterday my battery drained suddenly and when I charged it it read only 4% after charging overnight. I did another reboot and it did appear to charge, but now, the % battery left when I toggle the lock screen on no longer appears. It will show when the charger is plugged in. I rebooted multiple times, and did a battery pull also but still doesn't show the batter % left on the lock screen. Stock and unrooted. On JB 4.1.1 Verizon. Any ideas? Thanks in advance.
