iPhone battery draining faster than normal

[Justin]

Ok, I'm not sure if this is because of 2.2 or not, but my battery is dropping faster than it should be. I also recently setup my phone for iPhone development with xcode, but don't see why that would effect it.

One thing I did notice today I took my phone off the charger around 9am EST and by 11am I was at about 80% battery. I looked and the standby was 1 Hour, 59 Minutes and usage was at 1 Hour, 18 Minutes. I didn't use the phone for anything but checking email once or twice (just refreshing the inbox, not reading). Plus the phone has seemed warm last night when it drained fast.

I rebooted the phone last night and shut it off for like 15 mins as well. Still having the same problem today. I've synced it with iTunes again and shut off push email and going to see how it does later in the day, just wanted to know if anyone else has seen this?

Also, this is not jailbroken, so no background apps

That's quite odd...I get better battery life with my jailbroken 2G iPhone and that's while checking email, texting, and using iPod

Have you recently purchased this phone? If not maybe a restore (I know it's a pain) will help clear any "bug" that has come to kill your phone.

I also highly suggest taking it by the Apple store as you have made no modifications to it

[Justin]

Yeah, right now I'm just going to try a few different things so I can try to track down the problem before I do a restore. So far though since I did a fresh sync with iTunes and turned off push email the usage is in line with what I have actually used.

It seemed like something was stuck in the background running, but since I had shut down the phone a couple times not sure why that would happen. I'm hoping the sync resolved whatever was stuck running.

That happened to me when I upgraded to 2.1. The phone was actually hot to the touch. I did a hard reset, and everything was fine after that. I think it happened to Bad Ash as well.

A hard reset is the lock and home button hold?

Cjvitek is correct. Do a full restore from scratch via iTunes. The lock and home button hold down is just a simple reset. You must wipe your phone out completely via iTunes.

And when restoring RESTORE AS A NEW IPHONE! Can't stress that enough. Do not use a backup file.

Yeah, problem still seems to be happening, not as bad as earlier, but still draining too fast.

This really sucks. I just got all the provisioning and stuff setup for my phone in Xcode.

So this basically means I have to start at 2.0, with no images, text or apps or anything correct? Basically the same as if I got a brand new phone?

You lost me there... you want to be sure to be updated to the latest firmware 2.2. And yes, do a full restore via iTunes and do not use a back up to restore.

[Justin]

Yeah, been programming for 3 hours, that didn't make much sense.

Was just asking if it was like starting with a brand new iPhone (ie 2.0) like I did on July 11th. Sucks, but I guess it will be nice and run faster for a little while, so at least there is plus.

Hello Dizzy,

I thought I was the only one having an issue with yhr battery draining rather quickly since I upgraded to firmware 2.2. But I also installed some new apps and updated some old one right around the same time. I charged my phone last night around 10PM and used Loopt for a brief moment and then felt asleep. When I woke up and started checking emails and surfing the web a bit I got the 20% warning. Have talked on the phone or anything much since I charged. I wonder if loopt has an issue closing out? Come to think about it I have been checking Loopt lately maybe daily. I'm gonna do a soft resset and not use Loopt and see if I notice any improvements.
Another issue I have been having related to AOL mail failing to move emails to sub folders under my saved folder. It also won't allow my to delete items which essentially moves items to the Trash folder.
Thanx 4 starting this thread.
