The iPod Touch has a battery life of around 4-5 hours when simply browsing through your music collection or looking at photos, and about 3-4 hours when using Wi-Fi. If you need it to last longer, try a few of these tips.
Step 1
Lower the brightness slider somewhere to the left of the word "Brightness" above it. Auto-Brightness should be turned on if you regularly use your iPod in dim or dark places, as the display will dim considerably. If you're outside alot or always in lighted places, it increases the brightness and can make the battery life worse.
Step 2
Turn off "Ask to join networks". When on, iPod touch scans for networks every 8 seconds, using large amounts of power.
Step 3
Turn off Wi-Fi when not in use for long periods of time. When on, the connection must be maintained even when not being used, so it uses more battery power.
Step 4
If you are leaving iPod Touch for a short amount of time, and are going to come back and use it again later, press the Sleep/Wake button and it will make iPod Touch go to sleep. Starting up iPod Touch from its off stage uses a lot of power, and should be avoided as much as possible.
Step 5
If your iPod Touch is using Firmware Version 2.2.1, change the frequency that data is Pushed to the device. This can be changed through the Settings application.
Step 6
When listening to music, turn on your hold switch this disables power to your ipod controls thus saving power.
