Tech news blog Which? recently tested the top tablets for a variety of performance ratings. While the iPad Air tested below Samsung’s Galaxy Note 10.1 (2014 edition) for speed, Apple’s newest tablet swam circles around the others for battery performance.

Which? tested the Google Nexus 7, Techo Hudl, Amazon Kindle Fire HDX and HD, Samsung Galaxy note 10.1, and Apple’s iPad Air, iPad mini with Retina display, and iPad 2.

From the results, Apple’s full line of tablets outperformed all others for Internet use battery life, including the nearly three-year-old iPad 2.

“The iPad Air, iPad mini with Retina display and iPad 2 all performed better than the Android alternatives for web browsing. On a full tank, Apple’s iPad Air will last for 658 minutes of web-browsing – beating the 483 minutes offered by the longest-lasting Android tablet we tested, Samsung’s Galaxy Note 10.1 (2014 edition). Likewise, the iPad mini with Retina display features an impressive 614 minutes of internet usage, while Apple’s three year old iPad 2 managed a sterling 590 minutes.”

When it comes to video usage, the iPad Air still outperformed all other tablets. However, the iPad mini with Retina display faired below most others. Which? notes that larger tablets can make use of the space to include larger batteries, so smaller tablets may not do as well. Additionally, distibution of power matters. The Nexus 7 outperformed the iPad 2 thanks to its 3950 mAh battery.

“With the iPad Air, Apple has clearly been able to strike the right balance between design and battery life. It’s only 7.5 mm thin and yet still manages to offer a 8820 mAh battery that works well in conjunction with iOS 7.”
