The iPad's 10 hours of battery life is pretty amazing, but for those of us that use our iPad throughout the day, it's still pretty easy for it to run low. And there's nothing worse than trying to stream video from Netflix to your HDTV only to have that low battery message pop up and interrupt your show. Luckily, there are a few tips you can use to save iPad battery life and keep that from happening as often.
Adjust the brightness. The iPad has an auto-brightness feature which helps tune the iPad based on the light quality in the room, but this feature is not enough. Try going into the iPad settings and adjusting the brightness. The goal is to get it where it is still comfortable enough to read, but not quite as bright as the default setting.
Turn off GPS. The 3G model of the iPad comes with GPS, but most of us don't use the location services on our iPad as much as we use them on our iPhone. Turning GPS is a quick and easy way to save a little battery power while not giving up any features. And remember, if you do need GPS, you can always turn it back on.
Turn off Bluetooth. Many of us don't have any Bluetooth devices connected to the iPad, so all the Bluetooth service is doing for us is waste the iPad's battery life. If you don't have any Bluetooth devices, make sre Bluetooth is turned off in the general section of the iPad settings.
Turn off Push Notification. While Push Notification is an excellent feature, it does drain a little bit of battery life as the device checks to see if it needs to push a message to the screen. If you are looking to do the most to optimize your battery life, you can either turn Push Notification off completely, or turn it off for individual apps.
Turn off 3G. If you are at home or in an area that has a Wi-Fi connection, turning 3G off is a good way to save a little bit of your iPad's battery life.
