iPhone 3gs battery

Oct 16, 2011 2:59PM PDT

Lately, my 3GS battery uses itself up more quickly than, say two weeks ago. It charged every night and often gets down to 10% or lower by the evening. What might be causing this?

Bluetooth is on, was off.
Wifi is on, was off.
Your cell tower is farther away or moved.

updgrade to iOS 5

iOS 5 seems to eat more of my battery life than iOS 4, say by 10%.

Plus, quit all of your open apps. I find that a lot, imho, don't actually go to sleep while in the background and still draw power.
