Got an iphone4 as where i am the android is not supported. Happy with it so far but i notice my power on the phone goes very quickly.

For instant, last night at 1am it had around 55% power left, i turned it off and had the alarm on, at 6am i woke up, the battery had gone out of power...

Now im not use to these new phones, my last being a SPVC600 which would last 5-7 days on a full charge. But 55% in 5 hours??

I guess i either have a rubish battery in the phone or maybe a rogue process is running, maybe a program i have on the phone is acting up??

How can i check what is running on the phone, as in a Process check on a PC? and is the the iphone battery only menat to last 10 hours on a full charge?

Turn off 3G.
Turn off wireless.
Turn off Push notifications.
Turn off location services.

If you neuter the phone, the battery will last a reasonable amount of time.

More seriously, are you switching it off at night or just hitting the lock button and leaving it in standby? If you leave it in standby overnight, at least put it in airplane mode.
 
Mine has only dropped about 20% in 10 hours, so I'd say you have left something running. Do as vonhelmet suggests.
 
Double-tap the home button to bring up the multi-tasking bar. Hold a finger over an icon until they all start to wobble, then close each one by tapping the red (-) dot.

Airplane mode should result in the phone losing only 1-2% overnight, if that.
 
Mine drops 10% after 5 minutes if web browsing over GPRS and drops around 5% for a 10min call. Apple care said the battery would need replacing and should take it into a store.
OP, if your battery doesn't last more than 5 hours a day, then get the phone replaced like me. ;)

Airplane mode overnight? :confused: My iPhone (3G) only loses 5-10% overnight. You don't have to switch the radio off overnight on any other phone to get decent battery life, and you don't have to on the iPhone either.

If your battery lasts 10 hours with no usage, something is badly wrong. Try reinstalling the OS via iTunes. If that doesn't work, take it to the Apple Store.
 
Airplane mode overnight is a good idea, I didn't think of that. In my experience the iPhone4 battery is okay but nothing to rave about (3G, location services off)

I wish I knew more about what my background apps were doing though. I find the lack of information disturbing.
 
I wish I could could leave my iP4 alone to test it to see how long the battery lasts...but its far too addictive!

I find it much like my 3G's battery really, was hoping to see an improvement but havent yet maybe over time it will improve as ive only had my iP4 for 2weeks.

Does everyone try to get in the habit and kill all your MT apps that you dont use?
 
ok i think me using 3g apps a lot may account for the daily use of the power and i can only thing maybe one of the processes was left on over night without me knowing it. i charged it up at work at 6pm to 100%, checked gmail, FB and twitter, played a game or pool and its now on 95% after 3 hours.

i can only guess an app was running i didnt know.

The double tap on home button works, never knew that, cheers.

Well, the phone is in my room overnight, as my alarm, so I don't want it ringing or anything. For the iphone to work as an alarm, it has to be switched on, which is retarded. Put these things together, and it basically has to be in airplane mode.

Any other phone that I used as an alarm would be switched off overnight anyway, so in that sense the iphone is a step backwards.

Also, the 3G has a bigger battery than the 3GS, which I have, so perhaps that's why you lose less battery.
