“To separate the best from rest, every tablet Which? tests is tested in lab conditions to see how long it lasts when browsing the web on wi-fi and watching videos,” Tim Gee reports for Which? Tech Daily. “To ensure our tests are fair, we set the screen brightness to 200 nits (measured using a light meter) before performing each task, so every tablet has to perform in the same conditions.”

“As the size of the screen can make such an impact on battery life we’ve divided the tablets into two groups, those with a screen size of 7.9-inches and smaller, and those 9.4-inches and larger,” Gee reports. “The Apple iPad with Retina display not only beats the competition comfortably, it surpasses the Apple iPad 2 by almost 4 hours. The iPad 2 still manages around an hour longer than the next nearest challenger.”

Gee reports, “When it comes to 7-inch tablets, Apple is still ahead of the game with the new Apple iPad Mini managing over 13 hours of web browsing and more than 3 hours more than the next best challenger.”
