It should come as no surprise that
battery life
is i of the fundamental things we look for in a laptop calculator. What is surprising is which
brands and models
take the height spots when it comes to battery life. They’re not ever the usual suspects.

Why are we so obsessed with battery life? More than screen size, processing power, graphics bill of fare or number of ports, battery capacity is the commencement thing many of us think nigh earlier making a purchase, whether information technology’s a school laptop, business laptop or gaming laptop. After all, y’all don’t want your PC shutting down in the middle of a Netflix binge or
while taking notes in a long lecture class, and conveying effectually a
battery fill-in
is merely a hassle.

While at one fourth dimension Apple’s MacBooks (the MacBook Air and the Apple MacBook Pro) controlled much of the top of this nautical chart, the current winner comes from an unexpected identify:
Asus’ ExpertBook B9450F. The company’s ultralight business laptop has splendid battery life, which comes in at over 16 hours.

LG’due south Gram serial is all-time known for being very light, and the 14-inchLG Gram xiv is no exception at 2.5 pounds (even slim 15-inch laptops are usually over iv pounds). Only as well that, it ran for over 16 hours, which is uncommonly expert. Part of the surreptitious is that a larger 15-inch body just has room for a larger battery forth with the larger screen and larger keyboard. Dell squeaks into the top v with theXPS 13.

So many factors get into determining a laptop’southward battery life that it’s difficult to predict in accelerate how different laptops or different models of the same laptop will last based on specs (e.g., keyboard, hard drive, Retina display, number of USB ports, fingerprint reader) 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 effect: Bingeing video is an obvious drain, merely and then is running the CPU at superlative speed for crunching numbers or keeping the screen brightness cranked all the way up. Even modern laptops with skilful battery life will drain under those conditions.

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

  • The brighter and college the resolution of the screen, the more power it uses. So the typical ane,920×1,080-pixel screen on a sub-$500 laptop uses a lot less power than the flashy 4K, 500-nit brandish 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 take more battery optimizations than older ones.
  • Discrete graphics are more bombardment-intensive than integrated.
  • A backlit keyboard may take a small impact.
  • LPDDR memory uses less power than standard DDR — the “LP” stands for “low power,” after all — and a device with this type of memory will have longer battery life.
  • Gaming is the most mutual of the large battery-draining activities you can inflict on your laptop.
  • You can also extend the battery life of your device by adjusting settings similar making it go to sleep or plough off the display after a smaller interval and reducing the brandish effulgence.

And go on in mind, bombardment life isn’t everything. The Snapdragon-based Asus NovaGo lasts all day, for case, just we withal felt information technology made too many compromises to get at that place.

Based on the extensive battery testing conducted in the CNET Labs, these are the PCs with the longest bombardment-life scores that we’ve seen over 2018 and 2019. The acme five current performers are below, and afull list of the top 25 can be found below the v leaders.
