the battery indicators get more inaccurate as the battery gets older

try calibrating it, let it die (if you are patient enough wait a few hours after it dies), leave on the charger overnight and if the problem is not solved right away repeat this a couple of times. Generally speaking... after calibration is done, don't let it die for no reason, it's not good for Li-On batteries, especially when it happens frequently.
