iPod touch Battery Drainage Issue: SOLVED

[skiltrip]

I find the battery life on my touch 4g superior to both my 3g touch, and my old iPhone 4. Both the 3rd gen touch and iP4 destroyed the battery after only moderate gaming. The 4th gen touch seems to hold up a lot better.

Howdy, folks.

There are a lot of posts going around about how the new iPod touch 4G drains battery on idle/sleep mode. People would go to sleep with 100% battery and wake up with the 20% warning.

Firstly, let me say THIS IS NOT A PROBLEM WITH YOUR DEVICE.

Here's how to 'fix' a nonexistent problem:

Step 1: Bring up the multitasking drawer by double-tapping the home button.
Step 2: Hold down one of the apps in the drawer until they all shake with a close button.
Step 3: CLOSE OUT ALL APPS IN THE DRAWER.

Thank you, -fswmacguy

Being new to the iPod Touch I wasn't sure what to do after you got the apps to shake. I found out from another site you need to press the minus (-) sign to close out the apps. Before doing this I noticed I had almost all my apps open. Hopefully, this will solve my battery draining issues I am having. Thanks for getting me started on the process.

After testing various things, it's definitely the wi-fi that is draining the Touch during standby. Removing apps in the taskbar or disabling notifications does not change anything. Since my 2G with iOS 4.0 doesn't exhibit this, I'm going to assume this is an iOS 4.1 issue and not a hardware one.

I have a ipod touch 2nd gen 8 GB.
I put it in airplane mode and yes, the batt lasts.
So, the Wifi is the problem.

I uninstalled Skype and left Wifi on tonight. Let's see what happens.

Skype is the only major battery drainer for me. If I don't close that my iPod will be dead in the morning, but I can leave everything else open.

Apple's implementation of multitasking makes use of background APIs and suspended states. Having 10 apps open is no different from having 20 apps open if they're making use of the APIs. If I have an app open and it's not making use of the APIs, coming back to it is like loading a saved game on a gameboy (assuming it is built to support suspended state). If they are using the APIs, obviously it will drain battery. The multitasking implementation on its own, does not.

This true. In my opinion, the OP is giving false information. Apps do not run in the background unless they are specifically streaming music or similar. You'll notice an icon on your status bar to confirm this.

With ref. to the original poster "multi tasking drawer" - I was under the impression that this was just a list of the apps last used. Open a new app then close it - look in the drawer and it will be there. Removing it from the "drawer" just removes it from the list. It doesn't close it - it was already closed. Or have I got the wrong end of the stick!?

You're not completely wrong,

yes, they are in order of last opened but they still are "multitasking".

apple does TASK SWITCHING, rather than true multitasking except for a few apps such as Pandora and the like. when apps aren't onscreen, they are suspended.
