This has been driving me crazy for some time now. For the last month or two I have had what seemed to be random times when the battery in my 1G Touch 16GB would suddenly drain in just an hour or two of listening to music from a full charge. I have WiFi and all the other usual suspects turned off when this happens. One time I went to bed listening to music only to turn over to feel it hot to the touch and less then 20% battery in less than an hour. After trying dozens of combinations I have found a pattern that can be repeated. If I turn off WiFi (along with all the other usual battery saving tips) then turn my touch off to reboot it, I can then turn it back on and if I ONLY go into the music player, it will play music for almost 22 hours (right at spec so I do not believe I have a bad battery). But if I turn on the WiFi, do some Web surfing, check email, watch a YouTube video, etc. for a few minutes, then turn those off AND turn the WiFi back off and then go into the music player (without rebooting), the battery will always drain very fast and be dead within 1 - 3 hours from a full charge. Sometimes it gets warm, other times not so much but in this case the battery lasts a little bit longer. As long as I reboot I can always get good battery life playing music, but in general it seems if I use the WiFi it always goes into this high drain mode that I can not get out of until I reboot. This seemed to start happening with the 3.1.2 release. But I even tried down-grading back to 3.0 and it still does the same thing, but I know for sure that it didn't use to do this when 3.0 first came out. Also I thought it might be an app or some weird config setting, so I restored to factory setup condition, no apps, no backup restore (new ipod setup) and just a few songs to test with and it still does the same thing for all ver 3 firmware (3.0, 3.1.1, 3.1.2 & 3.1.3) What could have changed? Maybe a hardware issue in the WiFi area? But everything seems to work OK and the WiFi link and speed is OK. Any ideas or help appreciated. Now that I know what is happening I can kind of live with it, but I want to figure this out! Thanks for slogging through the long post.
