Why does my jailbroken iPod get so hot?

With my unbroken iPhone, the sudden heat was a case of the battery going to crap. My first phone stopped holding a charge and the second holds it not quite as well as it used to after a minor heat bump over a day or two.

There’s quite a few 3rd party apps that are processor heavy. If you use any of these for longer than 5 or 10 mins it could really get your CPU cooking.

Any specific apps in mind? I don’t want to harm my itouch’s battery life, which I already know isn’t that great.

Well, apps like VNSea would do it. What apps do you have? Tell me them and I’ll let you know.

Sometimes some apps secretly run in the background. Don’t install to many apps or at least not too many big ones

As MrBlogger says, it may be apps running in the background without your knowledge. (Of course, if you’re using Backgrounder to purposely run apps in the background, that’ll do it too.)

A good test would be to start your Touch and simply leave it running for a while without starting any apps, to see if it gets as hot. In that case, you may have apps that run on startup and in the background—that would be a good reason to try googling the apps you’ve installed and see if other uses have had issues with them.

(that should’ve been “if other users have had issues”)

i agree with the other people that commented, apps running in the background are the biggest thing that cause heat, thats why normal ipods and iphones only run one app at a time.
