Laptops with long battery life 2012

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

We run two separate Dell latitude d630 battery tests when we test laptops at CNET Australia — 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 business notebook nc6220 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 performance capability — Dell inspiron 1420 battery isn't the only thing to consider.
