Short battery life
I have been using my iPod touch 4th generation about 22 months, and I am feeling that my iPod's battery is really low.
So I have done some search on google, and found out that Apple supports the battery replacement, however, the price was above my range(since I am a student). So I am looking for ways to renew my battery and check the exact amount of battery life.
Also, I have found out some people replace their batteries themselves using tools and buying batteries that are not Apple certified. Is that a good solution? Is there any possibility that my iPod touch can be broken?
iPod touch (4th generation), iOS 5.1
