Apple’s iPad Air outperforms competing tablets by a significant margin when it comes to battery life, according to a new test conducted by Which? Test Lab, a consumer test organization in the United Kingdom.In a battery usage test that covered both Internet and video use, the iPad Air bested both the iPad 2 and the Retina iPad Mini, as well as tablets from competing companies like Amazon, Google, and Samsung...
With the Internet (web browsing) test, the iPad Air saw 658 minutes of battery life, or nearly 11 hours. The Retina iPad mini came in second place with 614 minutes of battery life, while the Samsung Galaxy Note 10.1 and the Amazon Kindle Fire HDX 8.9 lasted just 483 minutes and 481 minutes (eight hours), respectively. Apple’s iPad 2 also performed well, lasting 590 minutes.
In the video test, the iPad Air lasted quite a bit longer than its competitors at 777 minutes (almost 13 hours). The Kindle Fire HDX 8.9 and the Nexus 7 from Google came in second and third, at 714 minutes and 669 minutes, respectively. The Retina iPad mini and the iPad 2 fared decently at 660 and 604 minutes, respectively, while the Samsung Galaxy Note 10.1 came in dead last with 465 minutes of battery life (7.75 hours).
For the tests, Which? set all of the tablets at a brightness of 200 nits (what it calls a reasonable daytime brightness level) and checked battery life while web browsing over wi-fi (with 3G enabled) and during video playback. The tests may not be entirely reflective of real world usage given variations in browsing and video watching habits, but the experiment does give a clear overall view of the battery life of the iPad Air compared to its competitors.
