iPod touch Battery draining badly overnight on TWO 4th Gens

Aside from both my gf and I's battery issues.. our screen are perfect, no light leaks and no bad pixels.. Although hers has a higher blue tint and mine's a tad more warmer when I compare the two. I prefer a warmer tint - seems to produce colors more accurately than hers.. but it's down to preference i'm sure. I'm sure the LCDs have a wide tolerance during the QA process (if there is a QA process :p)

Anyways, back on topic, looking to hear from others on their battery life/issues.

Last night I used mine to play a couple of games before going to sleep.

When I finally put it aside the battery was around 40%.

10h of sleep later, I looked at it and the first thing I saw was the "20% of battery left" warning.

*Wifi was turned off the whole night*.

I received it Wednesday morning and in about 48h, this is the second time I'm recharging it. I believe something is wrong. But I don't know what.

How do you figure out if you have apps opened in the background?

When I double click the home button, it shows me a list of the latest apps I have used, but... does that mean they're running in the background?

When you double-click the home button... everything listed there is taking up some form of memory space.. whether or not if these apps are "sleeping" or just have a piece of virtual memory is hard for me to tell.. I'm assuming Apple let devs decide which apps are running with active processes in the background or not.. But something is indeed wrong.. will be trying something new tonight.

When you double-tap, that shows the apps that have been put in the 'background' via multi-tasking, so yes, they are running. To exit them, press and hold over an icon (like to rearrange the app icons), and they will have little minuses over a corner. Hit those, and then the apps will close.

EDIT: ^^ Beat to the punch. :p

Tonight I'll experiment with a full battery and see what is left in the morning. I'm going to have the WiFi on, as that is what most people will be using anyways, and I honestly don't believe it will make a significant difference (but I guess it might if it is a hardware problem, heh).

Thank you very much. I had about 30 apps on the multitask list. The thing is that they were exactly the apps I opened previously and in order to quit them I hit the Home button once. The ones I wanted to remain in the BG, I hit the home button twice and chose another app, but it seems that ALL of them instead of quitting just kept running in the BG.

Am I doing something wrong? Isn't it 1 click on the Home Button to quit and 2 to bring up multitask and leave the current app running?

As far as I can tell, it's one-click to put the app in the multi-task 'drawer', and I don't know of a way to 'exit' without it going to the drawer first (in my limited experience with iOS.)
Anyone confirm?

It's not truly running in the background. It saves the app in a suspended state, and basically keeps a mental note of where it saves, then closes down. It technically does not keep "running" in the background.
 
I'd says there's definitely something up with both of your units♠. I picked mine up on release day, have watched about 2 hours worth of video, listened to about 5-6 hours worth of music, and played games on it for about an hour. I haven't charged it except for the time that it was plugged in when I was syncing it, and my battery is at about 70% right now.

Coming from the iPhone -> Evo 4g the battery life on this thing is AMAZING (I understand this is different than a cell phone...don't bother pointing it out).
 
When you're in an iOS 4 app and you click the home button, the app does not quit. It's put into the drawer. If you want to quit the app, you have to open the drawer and quit it manually.

It's like how OS X works, where when you close a window the application is still running, but there are no documents on screen.

Personally, I think it should be the opposite. Click the home button once, app quits. Click the home button twice, app goes to the drawer.

Rephrase?
 
Why not those with battery problem have their iPod touch restore and then without add any other apps...just pure factory default and check if the battery still drain as before?

We just have to be sure if it is battery faulty or ios4.1 bugs.

I shall do this when mine arrives.

Just a fresh restore to make it default and I'll leave it in sleep mode all night.

I've noticed that too, it's recharging from completely flat to 100% (plug icon) very quickly.. I wonder if the battery-monitoring hardware is acting up on us then. I was beginning to think I got a lemon battery but it's looking more like an issue with the OS or something.

I even did a DFU mode restore and the draining happens on a completely untouched OS (no apps installed and nothing configured).

I'm shocked this forum isn't blowing up with the same issues. Unless me and my gf's iPods came from a bad batch of iPods..

You need to calibrate both batteries. Also, turn Push to manual in settings.
 
I wanted to post a thread about this battery drain but thought maybe it was something else. Glad to see I'm not the only one. I will try closing out apps in the app drawer though, that's news to me.

But yeah my GF's 2G doesn't drain this bad, I knew something seemed wrong. My concern is with no 3rd party apps installed on someone else's post it still drained.

I am also having the battery drainage issue. I fully charged it last night using an app called, "Battery Doctor". Than I used it for like 2 hours before going to sleep, and 20% of the battery was gone. Then today I took some pics, shot some videos, played a couple of games and listened to music. Then around 10pm tonight the battery was completely gone, so I had to recharge it.

I remember when I first got my iPod Touch 3G, I had to charge it like once or twice a week!
 
hey this might be a dumb question but how do you guys actually check the % of how much battery you have left? Is it through an app? I cant seem to find it in the General Settings. thanks!
 
I got my ipod touch 4 two days ago and i have only lost 10-20% every night. but my ipod feels like it overheats even after just ten minutes of a 3d game and the camera doesn't work for the facetime/camera app, but works for other apps.

THIS IS 100% CORRECT

but just to further add there are only a couple of things that can truly 'multitask' these are VOIP (the decive can listen for incoming voip calls - but only that part of the app runs in the background), music (the music part of the app can carry on in the background), GPS (either with the GPS chip or by cellular or wifi location).

EVERYTHING else is saved to the memory and suspended EXACTLY like putting your computer into SLEEP apert from the saved data is written to the flash memory and NOT the RAM.

It is NOT anything like on a windows PC or a mac PC both of which have full multitasking, it is also NOT anything like symbian, or windows mobile multitasking (both have full multitasking) or even android multitasking.

what I've said is ONLY what is correct nothing else
 
Just to clarify, what I posted was not incorrect.

It's not wrong. I never said the app remains running, you just implied it. In fact, I've gone out of my way to point out that apps are "frozen" when in the drawer in iOS4. See my other posts. ;)

I kept this thread in mind when I went to sleep tonight, woke up, and my battery had drained about 10%. not bad. It does tend to go really fast if I'm playin games or going online though. Anyone know how long battery should last goin online etc?
 
remember everyone that it does have multitasking so if you still got apps on then maybe thats whats draining it? i dunno but it seems right.
 
Update

Before going to bed, I had about 90% battery life.. I turned Wifi off and killed all apps in the tray..

This morning still had 90% left.

Onto the next test: Wifi on, no apps in the tray.
