Apple’s latest iPad like its predecessors promises to provide around ten hours of battery life. The high-resolution retina display and LTE connectivity of iPad needs much bigger battery which takes long time to charge. But the cost of keeping it running is a lot less. According to the Electric Power Research Institute (EPRI), the annual cost to charge an iPad is just $1.36.
Apple sold 67 million copies of its mobile products including iPads as of April. The cost of the cheapest available iPad is $500 (plus tax and AppleCare charges, if you want it). Charging the iPads consume electricity for which you have to pay some extra amount. The group of EPRI studied the power consumption of Apple Inc.’s iPad and conducted an experiment in Knoxville, Tenn. The group found that charging the Apple’s iPad round the year adds $1.36 to the electricity bill. By comparison, a 60-watt compact fluorescent bulb adds $1.61, a desktop PC adds up to $28.21 and a refrigerator adds $65.72 to the electricity bill in the U.S. It means, iPad uses 20 times less power than a desktop computer.

As devices get smaller and the components more efficient, energy costs are likely to decrease in the coming years, especially with more users moving away from PCs to portable options like the tablets and ultra-portables.
