Whatâ€™s Changed? iPad 2 Versus iPad 3
Apple is already considered the leader in tablet computing, as the first company to bring it into the mainstream. However, they had to go even further with the release of the iPad 3. Apple released the iPad 2 to the public in March of 2011. Exactly one year later, Apple released the iPad 3, which is referred to as the â€œnew iPadâ€, in March of 2012. Although both iPads have similar functions, there are some major differences between the two computer tablets. Processing and Storage (GBs) The iPad 2 has a 1 GHz processor. Apple increased the power of the iPad 3 with digital core Apple A5X chip for faster processing. This is a new chip design in comparison to the iPad 2 and is faster at downloading from the Internet or from other applications on the device. Currently, the iPad 2 comes in one option â€“ 16GB. It retails for $399 just for Wi-Fi connection, and $529 for 3G connection capabilities. The iPad 3 comes in 16GB, 32GB, and 64GB. It retails between $499 and $699 for only Wi-Fi connections. Adding the 4G LTE service will increase the cost to $899. Battery Design The iPad 2 has a 25 watt-hour lithium polymer battery with a running time, on a fully charged battery, of 10 hours. In comparison, the iPad 3 has a 17.5 increase in watt-hour, for a total of 42.5 watt-hour. It still uses the lithium polymer style battery. Although the running time on the iPad 3 is the same as the iPad 2, if you are using the 4G LTE, the battery time decreases to 9 hours. What is not taken into consideration is the use of the Retina display on the iPad 3. The brightness on this screen also decreases the usage time of a fully charged battery. Camera Function The original design of the iPad 2 camera comes with a 720p HD, fixed focus, 5x digital zoom, and a .7 megapixel video camera. The iPad 3 has increased its features for its camera in both picture taking and video. The iPad 3â€™s camera is a 1080p HD, the same 5x digital zoom, but comes with an auto focus rear camera, face detection, auto white-balance, and larger camera lens. Its video function is greater at 5 megapixels. Display One of the most talked about differences between the iPad 2 and the iPad 3 is the screen display. The iPad 2 and the iPad 3 both have the same size display screen of 9.7 inches, and are touch screens. The big difference is the resolution. The iPad 2 has a 1024 x 768 resolution with an LED backlight, and the iPad 3 has what Apple refers to as a Retina display. The resolution on this screen is 2048 x 1536. This is four times a greater resolution than the iPad 2. The iPad 3 also has a LED backlight.
