Battery, or software issue?
My ipod has had trouble with battery life. I will let it charge to full capacity, then walk out with it and within 5 minutes the battery bar falls to 75%, then 50%, then back to 75%, then 25%, etc. Then recently it kept freezing every time I selected a song. It was so bad I wasn't able to do anything but let it sit and come back the next day and try again. Today I used it and it would just shut off each time I played a song, then it showed something saying I need to do a fix or find an update or something, I can't remember. I'm currently recharging it again until it's full. Does it sound like a battery issue, or maybe a virus that was downloaded somehow to it, or both? Is there any software fixes out there if it is a software issue?
I doubt it is a virus, that would be very difficult to implement into an ipod and a song added to it would be incapable of causing a virus on it as well because it cannot execute code.
This sounds like a battery issue but it could be a logic issue as well. Replacing the battery in this model iPod should not be that difficult but it will require soldering.
Some helpful steps:
1. Do a full restore on the iPod through iTunes. If that doesn't work we rule out the software being corrupt.
2. Is the iPod hot when charging? This could be a sign of water damage
3. Does the iPod have a hissing sound when charging or when turning on or off? This could indicate a logic board issue.
4. If #2 or #3 are true take it to an apple store genius bar to see what they think.
5. After moving through these steps its now ok to attempt a battery replacement.
