My iPod has been running really slow and the battery has been draining much faster than normal. The battery has a full charge in the morning, by my lunch hour (4 hours later) playing just audio, the battery is down to 50%. Normally, as of a couple weeks ago, the battery is around 90% at lunch time.
Would a "format" and "reinstall" fix that?
Clarifications: I have "rebooted" a few times and it is not jailbroken.
