WiFi KILLING battery!

[Aviator_14]

I am having an issue where my battery seems to be draining excessively even while the Ipod is in sleep mode. My Ipod was fully charged before I went to bed and I unplugged it and put it in sleep mode, and when I woke up the next morning the battery was only at 60% so then the next night I did the same thing, but I turned the Wifi off and when I woke up the next morning the battery was at 95% charge . Also If I listen to streaming internet radio through my bluetooth headphones connected to the Ipod, then my battery really suffers and I only get about 5 hours of listening time from a full charge before I have to charge it again. Is anyone else experiencing this problem with the battery draining with Wifi turned on? If I listening to music without WiFi or bluetooth then I get about 12 hours before I have to charge the battery. Why is the Ipod using the Wifi and consuming power when it is in sleep mode? Also I can see the battery indicator drop immediately as soon as I start using the internet on the Ipod. Is this normal or is my battery weak and need to be replaced (it is still under warranty)?

Some of your experiences are normal or have been observed before. An iPod touch draining overnight in sleep mode is a common occurrence that has been experienced by many people. Unfortunately Apple has yet to completely fix the problem. For me, they helped it out with iOS 5 on my iPad 2 but it didn't fix anything for my iPod touch. That is why I just put my iPod in airplane mode before putting it to sleep. It is completely normal for your iPod's battery to drastically drain when listening to music over wi-fi sending it to your bluetooth headphones. Bluetooth is not a very power efficient wireless system. So you are having the iPod send and receive information over both wi-fi and bluetooth, that is going to drain it fast. That would even drain a full fledged notebook computer or iPad 2 pretty quickly.

The best thing I think you can do is conduct a battery drain test on your iPod. I don't know what iPod you have (you never told us) but go into iTunes and create a music playlist that lasts for 50 hours. You can repeat songs in the playlist if you don't have 50 hours worth of music, that is alright. Sync the playlist over to your iPod. Make sure the iPod is completely charged with wi-fi and bluetooth off. Plug in a set of headphones, put the volume at 50%, start the playlist, turn off the display, and walk away. Depending on which iPod touch you have, this could take longer than 40 hours to complete. Wait for the iPod to shut down on its own and then plug it back into your computer. Let everything sync and then open up that playlist you made. Highlight all of the songs your iPod played (you can do this by clicking on the first song, scrolling down, holding the shift key, and clicking on the last song) and iTunes will tell you how long your selection is. That is the duration your iPod was able to last. You might need to add the "last played" column of information to your playlist, simply right-click near the top of the other columns (i.e. the ones for artist, album, etc.) and select Last Played.

We can't answer any warranty questions as you did not specify what iPod touch you purchased, when you purchased it, and if you picked up a warranty with it.
