Ipod Touch 4g terrible standby battery life?

first question I have is was the 80% a result of a partial charge done just before going to bed, that created what's known as a "surface charge"?

Mine's been sitting idle for two days with no reduction in charge level. I do believe that 9 hours in standby mode (whatever that is) will affect battery life, so turn it off instead.

I was hopping this has been addressed. I have a previous iPod Touch and have gotten into the habit of turning on Airline Mode when not in use, much faster than turning the device off. I wish a button/switch combo could be assigned to Airline mode...that would be nice.

I have also turned of notifications as this seems to affect battery life as well. I kind of found them annoying anyways.

wow, an hour to drop it 20% sounds like more of a drop than my touchs. were you gaming, by any chance? or just using wifi?

I am glad i am not the only one...i went to bed with mine almost fully charged last night, read for 1/2 and hour on it...probably about 75% charged when i went to sleep and completely dead this morning...so frustrating...i never had this problem with my second generation one...

I wonder if what we're all experiencing is the power of location based advertising? My previous 2 generation touch had great battery life till the IOS update that leaves wifi on even when in hibernation/sleep... Whatever we're calling it now.

No.

Source? Isn't location based advertising about knowing where your device is at all times.

i've noticed that when when game center is running, the battery life is much shorter... might try turning that off...

Here is what I found. There are still some apps out there that are simply not iOS4 tested and compliant. If you have one of these apps running on the tool bar, then it will indeed drain your battery. I pretty much know which ones aren't and so I just make sure those babies are closed before hitting the sleep wake button when going to bed. I've not found any significant battery drain doing this. However, when leaving some apps there that aren't iOS4 complaints, it sucked my battery down like a fish in water.

I had this same issue on my iPhone 4, but I generally have gotten in the habit with it, to close down all the apps running and my battery life is great. Doing the same with the iPod touch 4 will generate the same results. Clearly there is something running that is draining the battery.

Remember power and resource management (suspend mode) is only working on those apps that are iOS4 compliant (you'll see iOS4 tested) on the app description.

My suggestion to those having this issue is just close out everything on your taskbar and see what happens to your battery life.

If you continue to have problems, go into Settings>General>Reset>Reset Network Settings.

Then re-enter your preferred network.

There are several threads on here that indicate resetting network settings helps improve battery drain. I have the new iPod touch and my iPod battery was draining overnight. After I reset network settings, my battery drain is dramatically improved, especially in standby mode. Now my battery only drains about 10-15% overnight at the most, even with wifi still on. If I turn airplane mode on, results are even better.

I don't know why this works, but it sure did in my case.

The keyword here is new. I have had many different ipods, and with all of them, the battery hardly lasts. Im not sure why this is, but the more you use them, the longer your battery will begin to last. When I first got both of my ipod touches, the would last for about an hour. now they last me several. Try using it alot, you will begin to see a change in the amount of battery it holds. Hope this helped!
