Sounds like your battery could be bad, because that sounds really bad... :unhappy: How old is your phone?

My non-scientific opinion is having the screen on is what uses the most battery, not your finger. The less the screen is on, finger or not, the lower the battery use.

Hehe, because I was testing in a condition of dark environment, screen brightness was low. (Not lowest because battery saver is off)

I was facing the same problem too in the beginning with my 12 day old 525, but now the battery backup has increased and lasts a day easily, with 2g net turned on all the time. The guy at the shop told me that when we use 3G on the device, the battery gets drained quickly, so switch to 2g for basic net usage and 3g for surfing.
