yes, it does, but it doesn't affect the battery too much.
Yes, it will. The higher the brightness. the less the battery life will be.
The iPod Touch will eventually run out of battery when it is locked, but it will not drain instantly.
Actually doing ANYTHING on your ipod touch whether it be listening to music, or pressing some buttons will drain the ipod battery. some things drain less battery then other things, but they all drain battery. (for example, listening to music does not drain as much battery as watching a video.) I do not know any buttons on the ipod touch called the hold button, but if you are talking about the button in the front with a square on it, that does not drain battery. if you keep holding it, a whole lot of options might open, but it does not drain battery. If it DOES drain battery, its so small of a drain that you won't notice it and it won't impact your ipod's performance
i normally do, before recharging
indeed, brightness and leaving the wifi ON when not in use are two of the things that can drain your battery really fast
settings/brightness
Your settings on your iPod Touch are set to a lower brightness than other iPod Touches. Go to Settings, and then General, and sift through there (usually under 'display') and you should find brightness, and you can adjust the brightness of your iPod touch from there.
Save battery
for sure If you connecting your netbook with Ipod via usb i don;t think your drain the battery! Just go for lowest brightness settings in your netbook it will help if you think its happening so!
Nope. Completely FREE! But, if you set it to check for mail too often, it will drain the battery from your iPod.
Depending on if it overheats, yes but otherwise it will just drain its battery and shut down
Personally, I turn down the brightness, which makes the battery longer. Also, less web browsing preserves it.
