Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
Turn off push notifications: Some applications from the App Store use the Apple Push Notification Service to alert you of new data. Those applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
Turn off push mail: If you have a push mail account such as Yahoo!, MobileMe or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > 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. If the global Fetch setting is set to Manually, you will not be able to locate your iPhone using the MobileMe Find My iPhone feature.
Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished 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: Excessive use of applications such as games that prevent the screen from dimming or shutting off or applications that use location services can reduce battery life.
Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.
Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries 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.
Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.
Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ and tap Flat.
Turn off 3G: Using 3G cellular networks loads data faster, but may also decrease battery life, 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.

Adjust brightness: Managing the screen brightness is the best way to extend iPad battery life. By default, your iPad has Auto-Brightness turned On. Auto-Brightness adjusts iPad screen brightness based on ambient lighting conditions; lowering brightness in low light conditions helps to extend battery life. You can adjust brightness yourself; go to Settings > Brightness & Wallpaper and drag the slider to the left to lower the default screen brightness.
Manage the use of downloaded applications: Use of certain applications, such as games that prevent the screen from dimming or shutting off or applications that use location services, can reduce battery life.
Turn off Wi-Fi: If you know you’re not going to be using Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you have iPad with Wi-Fi + 3G and use it to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
Turn off 3G (Wi-Fi + 3G model): Using 3G cellular networks when you’re out of range of Wi-Fi connectivity allows you to stay in touch but may also decrease battery life, especially in areas with limited 3G coverage. To disable 3G, from the Home screen choose Settings > Cellular and set Cellular Data to Off. Note: You will no longer be able to send or receive data via a cellular data network.
Use Airplane Mode (Wi-Fi + 3G model) in low- or no-coverage areas: Because your iPad always tries to maintain a connection with a Wi-Fi network or 3G data network (Wi-Fi + 3G model), it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
Minimize use of location services: Applications that actively use location services, such as Maps, may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.

Heres my analogy for batteries. Charging a battery is like cooking an egg. When the egg is 100% cooked you want to turn the heat off or it will get burned and ruined. Same with a battery you should unplug it when it's a 100% otherwise it will start to fry the battery and your battery life will become shorter and shorter. Never go to bed while keeping your phone/idevice in the charger.

Great guide 5/5

Although, I found that with my iPod Touch, silicon casing is much preferable, as opposed to a hard case - I believe that, should you drop it, the silicon can absorb roughly 60% of the initial "shock"

But thats just me

That would be perfect!

Do you know what it was called??
Need to get out :wtf:
