San Francisco - 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 on Wednesday at an event in San Francisco.
The new iPad will be 9.4 millimeters thick. That compares with 8.8 millimeters, for the iPad 2.
The weight of the Wi-Fi-only model is going up from 0.6kg to 0.65kg. Models equipped with modems for cellular data access are slightly heavier.
The company said the iPad is powered by a new chip with four processing cores, for smoother graphics.
The new iPad will go on sale on March 16.
There are nine flavours of the new iPad, with different access capabilities and storage amounts:
— Wi-Fi only, 16 gigabytes of storage, $499
— Wi-Fi only, 32GB, $599
— Wi-Fi only, 64GB, $699
— Wi-Fi and 4G cellular connection, 16GB, $629 (separate models for AT&T and Verizon Wireless networks)
— Wi-Fi and 4G cellular connection, 32GB, $729 (separate models for AT&T and Verizon Wireless networks)
— Wi-Fi and 4G cellular connection, 64GB, $829 (separate models for AT&T and Verizon Wireless networks)
The prices are the same as the iPad 2's at launch. On Wednesday, Apple said it is cutting the older version's prices by $100. It will cost $399 for the basic W-Fi model and $529 with cellular connection on the older 3G network. Both versions have 16GB of storage.
Pre-orders begin Wednesday. It will go on sale on March 16 in the US, Australia, Canada, France, Germany, Hong Kong, Japan, Puerto Rico, Singapore, Switzerland, United Kingdom and the US Virgin Islands.
