I have been recently getting fantastic battery life on my attic pushing 24 hours easily thanks to turning off background data and turning on only sync social networks over wifi. However recently my android system has been using up quite a bit of battery percentage as listed in battery manager. It is almost cutting my usual 24 hours in half. The only different thing that I have started using on my phone is nexus one live wallpaper which I thought would be listed seperately in battery manager. Any reason why androic system would increase use and harm battery life or is there any way to fix it?
