How to Extend Your iPad’s Battery Life
The much-touted ten-hour battery life of the iPad is a wonderful feature, but you can do some things to extend it even further. Here are a few tips to consider:
Keep tabs on remaining battery life. You can estimate the amount of remaining battery life by looking at the Battery icon at the far-right end of the Status bar, at the top of your screen.
Use standard accessories to charge your iPad most effectively. When connected to a recent model Mac or Windows computer, the iPad will charge slowly; charging the iPad on certain PC connections, on the other hand, drains the battery slowly.
Even so, the most effective way to charge your iPad is to plug it into a wall outlet by using the Lightning–to–USB cable (or Dock Connector–to–USB cable with pre-iPad fourth gen tablets) and the 10W USB Power Adapter that comes with your iPad.
The fastest way to charge the iPad is to turn it off while charging it.
Your battery may lose power if you leave it connected to the USB port on an external keyboard.
The Battery icon on the status bar indicates when charging is complete.
Your iPad battery is sealed in the unit, so you can’t replace it, as you can many laptop or cellphone batteries. If the battery is out of warranty, you may have to fork over more than $100 to get a new one.
Apple has introduced AppleCare+. For $99, you get two years of coverage, which protects you even if you drop or spill liquids on your iPad. (Apple covers up to two incidents of accidental damage.) If your iPad has to be replaced, it will cost you only $49, rather than the $250 it used to cost with garden-variety AppleCare.
That means $148 versus the $299 price Apple offered me to replace my iPad 5 when it died 14 months into its life (and Apple advised me that the company couldn’t service it). You can purchase AppleCare+ when you buy your iPad or within 60 days of the date of purchase.
