Heftier battery makes new iPad will be thicker and heavier; battery life unchanged

Apple’s new iPad will be thicker and heavier than the iPad 2 because it features a bigger, more powerful battery.

Even with a bigger battery, the battery life of the device stays the same: about 10 hours. That’s because Apple has quadrupled the screen resolution, which in turn requires more computing power.

Apple revealed the device Wednesday at an event in San Francisco.

The new iPad will be 9.4 millimeters thick, or 0.37 inches. That compares with 8.8 millimeters, or 0.34 inches, for the iPad 2.

The weight of the Wi-Fi-only model is going up from 1.33 pounds to 1.44 pounds. Models equipped with modems for cellular data access are slightly heavier.

The weight places the new iPad in between the original iPad and the iPad 2. However, the new iPad is still significantly slimmer than the first iPad, which was half an inch thick.

The battery capacity of the new iPad is 70 percent higher than for the iPad 2.

The new iPad will go on sale on March 16 in the U.S., Australia, Canada, France, Germany, Hong Kong, Japan, Puerto Rico, Singapore, Switzerland, United Kingdom and the U.S. Virgin Islands.
