If you’re like most people, you probably use your iPad to access the internet, play games, and take pictures and videos. But if you’re like me, you also use your iPad to charge it up. The new iPad has a built-in battery that can last up to 12 hours on a single charge. But if you’re using 4G LTE service, your battery will only last for 3 hours on a single charge. So if you want to keep your iPad charged up all day long, you’ll need to switch to 3G service. There are a few ways to do this. You can buy an adapter or upgrade your iPad’s battery. You can also try turning off background services on your device and then re-enabling them later when the battery is fully charged again. But the best way to save battery life is probably just to change over to 3G service!
Whether you live somewhere without 4G coverage, you live in a bad coverage zone, or you just want to conserve some battery life, it’s extremely simple to disable 4G / LTE on the new 3rd generation iPad and switch to 3G instead, which uses less battery life.
Note: We’ve not done formal testing yet to figure out how much battery life you might save, but there’s no question that 4G LTE technology uses a lot more battery overall, and it’s useful to know that you can disable it.
How to Disable 4G on the iPad
Head to Settings –> Cellular Data and switch Enable LTE from On to Off. As soon as you’ve done so, you’ll see the LTE in the upper bar change to 3G instead.
Of course, if you are sitting around your house with Wi-Fi enabled, there’s no reason for any G at all, so you can flip the Cellular Data off as well.
Note that flipping off the Cellular Data while at home should theoretically make sure that you are using less data from your plan.
