Finally there’s battery life. This is likely to be one of the most important considerations you have when choosing what laptop to buy. The best laptops need to be able to let you work – and play – for hours on end without you having to scramble for a power adapter. Modern laptops are getting ever more power-efficient, which has led to longer battery lives. For a laptop to be included in our best laptops list, it needs to offer a battery life of five hours or more.
Bear in mind that the battery life that the laptop makers claim their device has could be quite different to what you actually experience. This is because many laptop makers test their batteries in very controlled environments, with the laptop used in ways that you might not necessarily use. So, while a laptop might have a claimed battery life of 10 hours, you may find that when using it for certain tasks – like streaming high definition content – your battery life could run out faster.
That’s where our in-depth reviews come in, as we run a series of tests on each laptop in this best laptops guide to see how long the battery life lasts under certain conditions. If a laptop’s battery is ridiculously short (or impressively long) we’ll tell you.
