Battery problem!

maybe (i'm just thinking) that the battery icon hadn't loaded yet to tell ur the REAL battery % cus of the long time u had it on it lagged. So by u restarting ur ipod it refreshed it. correct me if i'm wrong but its probably correct.

 

This problem was discussed on the iPod Touch forum a while back, though I can't remember which thread.

Basically, I think the battery life is measured using a dynamic reading, so when the processor is sucking more juice (i.e. for startup), the battery sensor says "Hey, the battery isn't as strong as usual, it only feels like __%" and displays that much. Then when it refreshes a few minutes later, the new reading shows that the battery is actually fuller than originally thought.

This proves annoying when starting up to a "You only have 20% battery remaining" warning several days in a row, when you actually have at least twice that much.

Anyway, hope this helped.

 

While these responses are correct about how it reads your battery life - there is no way your battery should be draining that fast from just playing music. I can listen to music for a few hours and my battery doesn't go down at all. I only have to charge mine every few days and I use it heavily.

One thing I found was that SummerBoard was sucking my battery dry. I had read somewhere that everyone time you sleep your iPod (which is every time you press the lock button or it does it automatically), SummerBoard has to completely reboot. Not sure if this is true or not but I am sure that without SummerBoard my battery is much stronger.

So if you have it installed I would recommend getting rid of it and either get rid of crap apps you don't really need or rearrange your icons so you can fit all of your stuff on one window.

**ALSO: I highly recommend turning your brightness down to almost off. This will increase your battery life GREATLY. I have mine one click above the lowest possible setting. The only time you need it really high is if you are outside in the sunlight or something and you can always change it then.

**ALSO ALSO: I wouldn't turn your iPod off unless you really need to. It takes more juice to boot it back up again than to just let it sleep. If it's going to be off for a long time then I suppose, otherwise, sleep is esentially "off" but without having to reboot again, it just goes back to the state it was last in.

Hope this helps.

 

Isn't there an app in Installer that prevents Summerboard rebooting everytime?
