Battery draining all night playing nothing in airplane mode

[KevinPlusPlus]

I have been having a problem with my iPhone since I upgrade to 1.1.1. I have a 45 minute playlist I use sometimes when I go to sleep. What happens is that when I wake up, the battery is drained as if the phone has been playing all night and the Usage shows 7 hours more Usage time than when I went to bed. I check the "Last Played" column in iTunes after syncing the phone and the last music played was at the right time, about 45 minutes after I started my playlist.

I have tried rebooting the phone and resetting my usage data, and that worked for one night, but now the problem is back. I have also reproduced the problem with playing just one 4 minute song after resetting the Usage Stats, and when I wake the phone up 20 minutes later, it shows 20 minutes of usage, even though the song ended after 4 minutes.

All of these tests have been done with airplane mode enabled. Has anyone else had a similar problem or have any advise? Thanks in advance.

I cant answer your question, but I can add this. Three times now today my iPhone has shown it was playing something. The blue arrow next to the battery was showing. But when i go into the ipod there is no " now playing" button, but the blue play icon was still there. Also during thus the phone seemed a bit slugish.

I have been nowhere near iPod controls to trigue a play. And there is no music going to the external speaker, other sounds do however.

Maybe somthing similar is happening to you. This may also be related to 1.1.1 battery life issues some have reported. I was fine, until today. My battery is at 60% in 2 hours now. I did not have this problem before, but I did do another restore last night.

Interesting, that does sound related. It's like it's playing an empty soundless file. I too have nothing coming from the speaker during the time it's playing but not playing.

What's weird is that it doesn't happen all of the time for me, just some of the time. I haven't done a restore but based on your experience it doesn't sound like that would help. I have rebooted and reset usage data.

Ya it is odd. Since I last posted, it happened twice more. Once Safari crashed and it started "playing". My battery life has been HORID!

This was my fourth restore to 1.1.1, but this time I did a "restore from backup". The third time I did it too, but did not use it very long. The first two other times I set it up as a new phone.

I HATE restoring and having to re-sync all my data over the slow USB 1, but I think I may give it yet ANOTHER shot. Restore and setup as new, then sync data followed by music and such and see what happens.

I would certainly be curious to hear back if any of these methods solve the problem. I will also post again if I learn anything new.

just happened to me

I was reading this thread on my iPhone about 20 minutes ago. I put the phone down to finish cleaning up, and when I came back to the phone, the little play triangle was showing in the upper right corner. I had nothing playing though. Also, just the other night, when I went to bed, the phone was almost fully charged. When I woke up, I got the 20% battery warning.

I did update to 1.1.1, so I wonder if it is the culprit. I don't remember having this problem before with 1.0.2

When you updated did you have to re-sync all your music and such? My first update failed, so I had to restore all the software but did NOT restore my data.

I am wondering if doing a clean slate will fix this. I will let you know. My theory is that some file from 1.0.1/2 may get corrupted during the update. Its the only thing I can think of now. That is if anyone having this happen had a successful update or did not select "setup as new phone" and instead restored from a backup.

Clean update

I actually had a pretty clean update. No problems, and didn't need to restore anything. I did however perform a restore about a week earlier to remove AppTap so I could do the update with out any problems.

Ok, that helps. It means some "old" files were "carried over" to 1.1.1. I cant restore tonight, I need sleep but will tomorrow unless one of you want to give it a spin.

Like I said, no problems until I did another restore and then used a backup file which I had not before.
