Battery and Charging

iPad has an internal, rechargeable battery. Read on to learn how to charge the battery and identify supported iPad USB adapters.

To charge your iPad battery:

  • Connect iPad to a power outlet using the included cable and USB power adapter (use the table below to determine which adapter is intended for your iPad.)
  • Connect to a high-power USB 2.0 port using the included cable.


One of the advantages of low power tablet/iPad devices is that they will easily run for 10+ hours on a single charge and are therefore capable of getting through a heavy use school day. This is not so easily achieved with a laptop computer.

Where a laptop computer will quickly charge to over 80% battery in a short period of time though, the iPad is MUCH slower at charging and will take 5+ hours to charge from 0 to 100% and even longer if charged from a computer USB port. To ensure you always arrive at school in the morning with a fully charged iPad it's important to get into the habit of always putting your iPad on for a good long charge overnight. A quick charge in the morning or between lessons simply won't be enough to keep it going long term.

Battery conservation

If you find you are sometimes getting low on battery before the end of the day you're either viewing a lot of video content or you've set the screen to never go to sleep when not in use. One small thing you can do to reduce battery drain is to turn off unnecessary services.

  • If you're not using an external keyboard there might not be any need to keep Bluetooth turned on permanently. In IOS7 it's very easy to quickly turn Bluetooth on and off via the Control Centre which opens with a swipe up from the bottom of the screen. The top middle button in Control Center which looks like a B toggles Bluetooth. In IOS6 Bluetooth can be turned on and off via the Settings screen.
  • Similarly, Airdrop is something which doesn't need to be kept on all the time. It's also just as easy to switch on and off via the Control Centre.

Optimise your Battery life

There are two simple ways you can preserve battery life — no matter how you use your device: adjust your screen brightness and use Wi-Fi.

Dim the screen or turn on Auto-Brightness to extend battery life.

  • To dim, swipe up from the bottom of any screen to open Control Centre, and drag the Brightness slider to the left.
  • Auto-Brightness adjusts your screen to lighting conditions automatically. To activate it, go to Settings > Display & Brightness, and set Auto-Brightness to On.

When you use your device to access data, a Wi-Fi connection uses less power than a cellular network — so keep Wi-Fi on at all times. There are two ways to turn on Wi-Fi:

  • Swipe up to open Control Centre, tap the Wi-Fi icon and log in to a Wi-Fi network.
  • Go to Settings > Wi-Fi to access a Wi-Fi network.

View Battery Usage Information

iOS 8 is designed to be the most battery-efficient iOS ever. And it gives you more precise ways to manage your device’s battery life, because you can see the proportion of your battery used by each app (unless the device is charging). To view your usage, go to Settings > General > Usage > Battery Usage.

Here are the messages you may see listed below the apps you’ve been using:

Background Activity. This indicates that the battery was used by the app while it was in the background — that is, while you were using another app.

  • To improve battery life, you can turn off the feature that allows apps to refresh in the background. Go to Settings > General > Background App Refresh, and set the switch to Off.
  • If the Mail app lists Background Activity, you can choose to fetch data manually or increase the fetch interval. Go to Settings > Mail, Contacts, Calendars > Fetch New Data.
