iphone 3gs dies to fast!?

Hello

Try switching off some of the push notifications and location settings this all consumes power and is of little benefit to you.

I doubt the update is your problem, maybe battery after two years is due replacement.

I also have a pantech telephone that my son have been given me for Christmas. this is 3 G and has an extremely enormous show and that i do no longer use it that in many situations, yet I ought to cost it the different nighttime. My previous telephone with a small show lasted for days. I emailed pantech and that they mentioned the telephone does greater and has a great show so this is going to must be charged greater in many situations. this is purely the way it extremely is. i've got observed that the bigger show makes use of greater skill, purely like my digicam does. the internet is definitely a battery hog.

Press the home button twice. Hold on an app in the pane, and press the red minuses on all the apps. Do this extremely often from now on.

is your brightness up all the way ? thats a battery killer for sure. Turn off some push notifications, turn off 3g if you arent using it.
