HTC Sensation — Battery Life -- It's Hot and It's Cold, It's Yes and It's No!

So, had my Sensation for a while now and I must say that the phone's battery life varies considerably based on factors over which I seem to have little control. Example: a few days ago, the battery was at 20% after just 6 or so hours! Fully charged. I have deleted many juice-wasting apps so I'm not sure exactly what the problem is. Thanks in advance for your help!

That is strange. Try turning off data and see if that helps. You could also install an app like Juice Defender to control which apps use power.

That IS strange...I wonder what's going on. Six hours is pretty pitiful.

I had really bad battery life, even after I did everything I could to tweak the phone! I replaced the battery and now it's much more energy efficient. If you are certain you have done everything you can as far as tweaking the phone to save power, try replacing the battery.
