Laptops with long battery life 2012 - Test Battery Life

Published on by Laptop Battery Life

As we review laptops throughout 2012, we’ll add their battery life stats here. If battery’s the most important thing to you, this is the place to look.

We run two separate battery tests when we test laptop’s battery life — a heavy test, which turns up screen brightness and volume to full and plays back a 720p H.264 video; and a light test, which sets screen brightness to 40 per cent and visits three different websites every 20 seconds until Dell inspiron e1505 battery exhaustion.

While our database is still building due to introducing these benchmarks in November 2011, we will keep updating this article throughout the year as laptops come in for review, with the eventual aim of splitting the charts into screen sizes. Keep in mind that there’s a massive spread here in both size and performancecapability — battery isn’t the only thing to consider.
