The new iPad requires a lot more power than the iPad 2. How much more power? So much that despite an astounding 70% increase in the new iPad’s battery capacity (42.5 watt-hour up from 25 watt-hour), it will still run for the same amount of time as the iPad 2 on a single charge. The new iPad is a power-hungry beast and, therefore, knowing a thing or two about its battery is more important than ever.
If you’ve owned any type of portable device for an extended period of time you’ve probably noticed that its battery gets worse with time. You may have wondered what you could do to maximize your device’s battery life or even suspected that a short-lived battery was defective, but didn’t know what to do about it. Maybe you’re interested in extending the usage time you get out of a single charge or need even more battery power than your Mac’s internal battery has to offer, but don’t know what to look for in an external battery pack. This is a two-part guide on the battery basics everyone needs to know. It’s aim is to give you useful information about the batteries used by all of your Macs – including the new iPad.
