Cyanogen rom - not charging after drains out
I have note 2 with twrp recovery installed. I flashed cyanogenmod 10.1.3 and i have 2 problems:
-1: after the battery drains completely, i plug the phone and the battery shows up but it doesn't fill up (no animation, just an empty battery that normally would fill up). I long press the power button but the phone doesn't turn on. I have to do the 3 button combo, to start into recovery so i can turn it on from there. So i can see that it charges but if the battery completely died, i cannot start the phone normally.
-2: i have 16 gb but the phone has only 10 available, total space is 10,46 to be exact. I know that it should have 13,... But i think i have to format it somehow because part of the memory is occupied like i was using a samsung rom.
