iPhone 4 battery drain over night?

Double click on the home button and kill all the apps before you go to sleep.

 

try to turn of the wifi and see what effect that has on the battery life.

 

these aren't android phones. No need to do that. no need to turn off Wifi or any other silly thing.



If you aren't happy with battery performance, go to Apple genius bar. They will replace your iPhone. If your battery is draining that much over 6-7 hours, yes its the battery...bring it back.

 

my ipod touch 2g drains the battery after a day with wifi on but can hold its charge for a week without the wifi on.
note on both scenarios i did't do anything with the ipod

 

The apps run in the background and can drain the battery life. Skype is known to do this.

 

Try the suggestions that have been given first before worrying that something is wrong with your phone.

 

The apps are still running in the background even when the phone is on standby.

 

The battery takes like 20 full cycles to be at peak condition.

 

Are you in a bad service area where you sleep? My room is in a basement and when if I don't put my phone into airplane mode it searches for signal all night and kills itself (dead battery, it doesn't jump off a roof or anything).

 

They are. If you have an app running in the background that is streaming something that will surely do it. It all depends on your usage. Have you ever killed the apps running in the background before?

 

I closed all open apps last night. iPhone was at 98% at 11 pm. Woke up at 6:00 am it was at 89%. Got my 1st Verizon iphone Monday.

 

Sounds like something wonky is up with your phone....

I went to bed at 11 last night and my phone was fully charged 100%. I woke up this morning at 5am and it was at 95%.

Don't know what is going on....

This is exactly what you need to do. Too much running in the background can drain the battery much faster than normal.

 

OP already called Apple. There is most likely nothing wrong with his phone. This is a simple problem with a simple solution that many iPhone newbies encounter.

 

This isn't android?

 

Unless you have Skype and/or a program that isn't suspended for "multitasking" losing 53% of the battery in 8 hours, while in standby isn't normal.

To the OP, I would do a full restore and set up as new phone, and see if the problem persists.
