To find out which of the tablets available in market has the longest battery life, ‘Which?‘ from UK, conducted a test on a number of tablets. The tests were conducted for browsing web at 200 nits brightness. They divided tablets in two categories based on the size of the screen:
- Small-screen tablet (screen size of 7.9-inches and smaller)
- 10-inch tablets (screen size 9.4-inches and larger)
Surprisingly, Apple wins in both categories in terms of battery life – that too with a large margin. In 10-inch category Apple’s iPad with Retina display topped with a battery life of 811 minutes. The second was Apple’s iPad 2 with 590 minutes battery life. The third was Sony’s Xperia Tablet S with 534 minutes of battery life. The average of all 16 tablets was found to be 451 minutes.
In small-screen category, Apple’s iPad Mini was again the clear winner with 783 minutes of life. Amazon Kindle Fire HD came second with 591 minutes. Kindle Fire (non-HD) however ran only for 437 minutes in the test. The average battery life of 10 7-inch tablets was found to be 478 minutes.
