Battery Draining Since Update

[jennifer_im]

I recently accepted an updated from ATT to my iPhone 3GS and now the battery seems to be draining very quickly. Anyone else experiencing this issue? How to solve?

How Bright is your screen ? Restart to close all current running apps . And if your Jailbroken how fancy is your theme you are running ?
