My iPod Touch 5G gets hot when using any app.
HI. My iPod get's very warm-hot whenever I use ANYTHING. Even if it's the only app running. Sometimes it gets uncomfortably hot to hold it. I have left it off for awhile to cool it off, but just heats back up again. (note: the top of the iPod heats up at the top mostly. that's where the battery is.) I have owned my iPod for less than a year, but I did purchase it used off of eBay.(it was 'Seller Refurbished') are there any ways to fix my problem, or is my battery just worn out? I do not have a warranty and do not have the money to repair it. Thanks in advance!
iPod touch, iOS 9.3.1, null
