Don't you hate it when you're iPhone or iPod Touch runs out of battery when you're playing your favorite game, listening to your favorite music or watching your favorite movie? It's time to put and end to it, or at least minimize the chances. Here are a few tips on how to prolong your iPhone or iPod Touch battery life!

Stay Updated with the Latest Firmware
Make sure you stay up to date with the latest firmware, as new firmware updates usually include more battery-efficient code.

Lock your Device
Whenever you aren't using your iPhone or iPod Touch, always lock it to preserve battery life. Also, use a short 'Auto Lock' time.

Adjust the Brightness
Turning the brightness down as much as possible is another good way to extend battery life. To do so, go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. Also, turning on Auto-Brightness enables the screen to adjust the brightness automatically based on the current lighting conditions. To do so, go to Settings > Brightness and set Auto-Brightness to On.

Turn off Wi-Fi
Whenever you're not using Wi-Fi, for example when you're playing games, listening to music or watching movies, you should turn it off. To do so, go to Settings > Wi-Fi and set Wi-Fi to Off.

Turn off Bluetooth
Whenever you don't use Bluetooth it is suggested to turn it off, turning it off will save battery life. To turn Bluetooth off, go to Settings > General > Bluetooth and set Bluetooth to Off.

Turn off EQ
If you apply an equalizer setting to song playback on your iPhone, it can easily drain your battery, turning it off will prolong your battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. If you added EQ to songs directly in iTunes, you’ll need to set EQ on your iPhone to Flat in order to have the same effect as Off because the iPhone keeps your iTunes settings intact. To set EQ to Flat, go to Settings > iPod > EQ and tap Flat.

Turn off 3G
Although using 3G cellular networks loads data faster, it may decrease battery life faster, especially in areas with limited 3G coverage. To disable 3G, from the Home screen choose Settings > General > Network and set Enable 3G to Off. You will still be able to make and receive calls and access cellular data networks via EDGE or GPRS where available.

Turn off Push Mail
If you use a push mail account such as Yahoo!, MobileMe or Microsoft Exchange, turning off push mail when you don’t need it can help prolong battery life. To do so, go to Settings > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.

Fetch New Data Less Frequently
Some applications such as Mail can be set to fetch data wirelessly at specific intervals. If you fetch data in short intervals, your battery life is bound to decrease. Fetching new data manually is a good way to help increase battery life, to do so, from the Home screen choose Settings > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.

Auto-Check Fewer email Accounts
Another way to save battery power is to check fewer email accounts. This can be done by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.

Minimize Use of Third-Party Applications
The use of applications excessively such as games that prevent the screen from dimming or shutting off or applications that use location services can drastically reduce battery life.

Use Airplane Mode in Low- or No-Coverage Areas
Since your iPhone is always trying to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.

    This is very nice article, I just recently bought an iTouch, and tend to use a lot of battery when playing games... Would you suggest any games that are worth getting?
