Which Tablet Has the Longest Battery Life?
Which.co.uk has published two infographics comparing the battery life of 10-inch and 7-inch tablets.
Each time we test a tablet we check the battery life for web browsing over wi-fi, over 3G (if relevant) and for video playback. To keep the tests fair we set the screen brightness to 200 nits (a reasonable daytime brightness level) using a light meter to ensure no tablet has an unfair advantage by using a low default brightness setting. We also test how long the battery takes to fully recharge.
