Reducing battery consumption as much as possible on the iPad not only extends the time between charges but also extends the overall life of your iPad battery. Here are few suggestions:
Dim the Screen. The touch screen drains lots of battery power, so dimming it reduces that power. On the Home screen, tap Settings, tap Brightness & Wallpaper, and then drag the slider to the left to dim the screen.
Cycle the Battery. All lithium-based batteries slowly lose their charging capacity over time. If you can run your iPad on batteries for 8 hours today, later on you’ll be able to run it for only 6 hours on a full charge. You can’t stop this process, but you can delay it significantly by periodically cycling the iPad battery. Cycling – also called reconditioning or recalibrating – a battery means letting it completely discharge and then fully recharging it again. To maintain optimal performance, you should cycle your iPad’s battery every one or two months.
Slow The Auto-Check on Your E-Mail. Having your e-mail poll the server for new messages eats up your battery. Don’t set it to check every 15 minutes. If possible. Ideally, set it to Manual check if you can.
Turn Off Push. If you have MobileMe account, consider turning off the push feature to save iPad battery power. Tap Settings, tap Mail, Contacts, Calendars, and then tap Fetch New Data. In the Fetch Data screen, tap the Push setting to Off and tap Manually in the Fetch section.
Paradoxically, the less you use your iPad, the more often you should cycle its battery. If you often go several days or even a week or two without using your iPad (I can’t imagine!), you should cycle its battery at least once a month.
Minimize Your Tasks. If you won’t be able to charge your iPad for while, avoid background chores such as playing music or secondary chores such as organizing your contacts. If your only goal is to read all your e-mail, stick to that until it’s done because you don’t know how much time you have.
Put Your iPad Into Sleep Mode by Hand, If Necessary. If you’re interrupted – for example, the pizza delivery guy shows up on time – don’t wait for your iPad to put itself to sleep because those few minutes use up precious iPad battery time. Instead, put your iPad to sleep manually right away by pressing the Sleep/Wake button.
Avoid Temperature Extremes. Exposing your iPad to extremely hot or cold temperatures reduces the long-term effectiveness of the Toshiba PA3534U-1BRS Battery. Try to keep your iPad within a reasonable range of temperatures.
Turn Off Wi-Fi If You Don’t Need It. When Wi-Fi is on, it regularly checks for available wireless networks, which drains the battery. If you don’t need to connect to a wireless network, turn off Wi-Fi to conserve energy. Tap Settings, tap Wi-Fi, and then tap the Wi-Fi Setting to Off.
Turn Off GPS If You Don’t Need It. When GPS is on, the receiver exchanges data with the GPS system regularly, which uses up Dell CF623 Laptop Battery power. If you have a Wi-Fi + 3G version of the iPad and you don’t need the GPS feature for the time being, turn off the GPS antenna. Tap Settings, tap General, and then tap the Location Services setting to Off.
Turn Off Bluetooth If You Don’t Need It. When Bluetooth is running, it constantly checks for nearby Bluetooth devices, which drains the battery. If you aren’t using any Bluetooth devices, turn off Bluetooth to save energy. Tap Settings, tap General, tap Bluetooth, and then tap the Bluetooth setting to Off.
If you don’t need all three of your iPad’s antennas for a while, a faster way to turn them off is to switch your iPad to Airplane mode. Tap Settings, and then tap the Airplane Mode switch to the On position.
