5 Best Battery Life laptops

Battery life is one of the most important features to look for in a laptop. As such, you will want to find out which laptop brands and models take the top spots. They’re not always the usual suspects.

Why are we so obsessed with battery life? More than screen size, processing power or number of ports, it’s the first thing many laptop buyers think about before making a purchase. After all, you don’t want your PC shutting down in the middle of an important presentation or while taking notes in a long lecture class.

So many factors go into determining a laptop’s battery life that it’s hard to predict in advance how different laptops or different models of the same laptop will last based on specs or price. How the manufacturer implements power-saving measures for the processor, screen, networking and peripherals can have a big impact, for example, in addition to the usual suspects. And how you use it has the biggest affect: bingeing video is an obvious drain, but so is running the CPU at top speed for crunching numbers.

However, there are a few rules of thumb when it comes to selecting a model that will last you all day:

  • The brighter and higher the resolution of the screen, the more power it uses. So the typical 1,920×1,080 screen on a laptop uses a lot less power than the flashy 4K, 500-nit display on a pricier model.
  • For Intel Core processors, the Y series uses less power than U which uses less power than H, and newer CPUs tend to have more battery optimizations than older ones.
  • Discrete graphics are more battery-intensive than integrated.
  • Keyboard backlights may have a small impact.
  • LPDDR memory uses less power than standard DDR — the “LP” stands for “low power,” after all.
  • Gaming is the most common of the big battery-draining activities you can inflict on your laptop.
  • You can also extend your battery life by adjusting settings like making it go to sleep or turn off the display after a smaller interval and reducing the display brightness.

And keep in mind, battery life isn’t everything. Here goes some of the other features to look for + the most important one: battery life. Based on the extensive battery testing conducted in the CNET Labs (www.cnet.com), these are the PCs with the longest battery-life:
