My HTC One running software version 4.3 loses battery life at about 1% per minute when in use. This just started occurring recently. When I'm using it I'm mostly messaging or browsing facebook/other apps which used to work fine. I have battery saver on and also applied some other tips I read about to preserve battery life. When I check battery usage it says the android system is using 93% of the battery. Is there a way to reload the software or go back to an older version?

Re: Battery drain?
A couple of things you can try:
1. Do a system cache partition wipe, which can sometimes clear out an old piece of data stuck in the system cache that is messing things up (how about that for a highly technical explanation?). You won't lose any personal data or settings. [Only registered and activated users can see links. Click Here To Register...]
2. Install a good battery monitor app like [Only registered and activated users can see links. Click Here To Register...]to get a more detailed breakdown of battery usage.
