Lenovo is widely known for having excellent keyboards, and business-oriented systems. But how do the company’s offerings stack up in the battery life department? Here, we take a look.
How we test battery life
We measure laptop battery life using the Peacekeeper Web browsing benchmark, which leans heavily on JavaScript. JavaScript is a commonly used programming language that’s found in content strewn about all over the Internet, making Peacekeeper a solid way to evaluate laptop endurance.
We also tune down every display’s brightness to about 100 lux. Most people don’t keep their monitors and laptops at full luminosity, so to us, 100 lux sounds about right as far as typical user settings go.
Without further delay, here are the five Lenovo laptops with the best battery life.
5. Lenovo Yoga 2 13 inch
The acrobatic Yoga 2 13 inch will flip its way into your heart on the strength of its superb 1080p display, beefy Core i5 processor, and spacious 500GB hard drive.
Of course, lets not forget its battery life, which clocked in at 5 hours and 29 minutes. Sure, that’s not a world beater overall, but it’s not terrible either. The Yoga 2, like the Flex 2, is also quite affordable. You can snag one for $800.
4. Lenovo Flex 2 15
Not only does the Flex 2 15 offer solid battery life (five hours and 42 minutes according to our tests), but it’s one of the better bargains you can get your hands on as well.
You can grab the Flex 2 15 right now for about $700, and that will net you a system with a 1080p display, Core i5 CPU, and a roomy 500GB hard drive. Plus, the keyboard here is enjoyable to use as well. Not bad for well under $1,000.
3. Lenovo N20P Chromebook
In case you didn’t realize, Lenovo also puts out Chromebooks, along with Windows laptops. The N20p, which is one of the company’s newest Chrome OS-powered notebooks, boasts an impressive battery life mark of seven hours and one minute.
On top of that, as is often the case for Lenovo, its keyboard and touch-pad are both a pleasure to use. At just 2.8 pounds, it’s pretty easy to carry around, and promises to never wear you down while offering fantastic endurance.
2. Lenovo ThinkPad X240
This isn’t the only ThinkPad on the list, which is a testament to the fact that Lenovo’s business notebooks are built to power through the rigors of the typical workday, as opposed to simply just getting you through them.
The Lenovo ThinkPad X240 lasts seven hours and 33 minutes (with help from an extended battery) in our Peacekeeper benchmark, but it brings much more to the table than endurance alone.
For instance, its luminous IPS display makes it easy to see stuff on screen, and the system is well built also. On top of that, it features a large wrist rest and touch-pad, along with an excellent keyboard. The latter item is something the ThinkPad series has been famous for.
Good thing the X240 is sturdy too, because its warranty only lasts for one year, while competing models offered more when we reviewed this laptop.
1. Lenovo ThinkPad T440s
If you want a notebook that might be a descendent of the Energizer Bunny, go for the Lenovo ThinkPad T440s.
This unit, paired with an extended battery, lasts a whopping 14 hours and 32 minutes on a single charge. That absolutely crushes everything we’ve tested in the last year.
On top of that, the T440s boasts a fantastic keyboard, though the touch-pad is problematic. Our review unit packed a solid slate of specs, including an Intel Core i5 processor, 8GB of RAM, and a 128GB SSD. That should be more than enough to get you through the day, whether you’re multitasking from nine to five, or laboring by the moonlight.
