I have the current gen iPod Touch and I only get about 8hrs of battery life and that's with the wifi off most of the time.
Being way too thin isn't good. No bueno![]()
The A7 is proven to have better battery life than the A5 (the one in your iPod) and more speed. You can't compare your iPod Touch to the next gen's A8 processor based on your usage of an iPod touch with a soon to be 3 generation old processor.
Use some common sense man.
