My phone is giving inaccurate readings of battery level
It is not very uncommon for Cyanogen to have some problem with battery status reading. Things you can try:


Turn off the phone and take off the battery for a while;
Let the battery fully drain and then reset the battery calibration on clockwork recovery;
Try an app like this.


Note: I'm not sure why, but when I changed my battery visualization to a percentage view instead of the default (in the Cyanogen configuratons), the battery lectures of my smartphone started to give me wrong readings. When I switched back, it got back to normal after a fully recharging.
