Laptops with the Longest Battery Life
No matter how stacked its specs are, a laptop is useless if it can't hold a charge. Fortunately, there are plenty of notebooks that go the distance. Using our Laptop Mag Battery Test (continuous Web surfing over Wi-Fi), we've identified the 10 longest-lasting notebooks on the market. We're talking anywhere from 9 hours to more than 20 hours of endurance, which should more than suffice for that cross-country fight, long day of meetings or multiple, back-to-back classes.
Lenovo ThinkPad T450s
Our favorite business laptop lasts for 15 hours and 26 minutes on a charge with its extended battery, which is long enough to last through a flight from New York to Taipei. During that time, you'll enjoy the 14-inch ThinkPad T450s' sharp 1080p display, durable chassis, speedy Intel 5th Generation Core Series processor and best-in-class keyboard. Lenovo's Power Bridge technology even lets you swap out the battery without powering down first.
Lenovo ThinkPad X250
Some ultraportable laptops skimp on endurance by using slimmed down, sealed-in batteries. The ThinkPad X250 bucks this trend by lasting 15 hours and 12 minutes with its six-cell battery on board. With a starting weight of under 3 pounds (using the extended battery adds 0.4 pounds), this 12.5-inch notebook is small and light enough to take anywhere, but functional enough to use as your productivity workhorse. A snappy keyboard, full-HD display and hot-swappable batteries complete the X250's impressive package.
Acer Aspire One Cloudbook
When it comes to price per hour of battery life, Acer's $199, 14-inch Aspire One Cloudbook has every other system beat. On Laptop Mag's Battery Test, the Cloudbook lasted a staggering 14 hours and 43 minutes on a single charge, 2.5 hours more than the next-closest budget machine, the Asus X205. You also get a big 14-inch screen, a sturdy body, a full-sized keyboard and Windows 10 instead of Chrome OS. So if you're looking for an affordable system that doesn't need to be tethered to an outlet, this is the laptop for you.
Toshiba Portege Z20t
Lasting 14 hours and 37 minutes in laptop mode (and 7:29 when docked), the jet-black Toshiba Portege Z20t is among the machines with the best endurance on record. The slick design — which combines a sleek tablet and a slim keyboard into an elegant 2-in-1 — is nothing to sneeze at, either. We love the bright and crisp 12.5-inch, 1080p display, as well as the included Wacom-powered stylus that made it a breeze to use the multitouch display.
Apple MacBook Air 13-inch (2015)
The latest MacBook Air keeps the same sleek design as its predecessor and adds a 5th-gen Intel Core i5 processor and even faster flash storage. And, with a 14-hour runtime, it lasts nearly 2 hours longer than before. Add in OS X and its useful Continuity features, and it's easy to see why the $999 Air is one of our favorite ultraportable values.
Not only does the Asus EeeBook X205TA offer more than 12 hours of battery life, but it's also cheap. At $199, it gives Chromebooks a run for their money while offering Windows 8.1 and solid everyday computing performance. That's all while being clad in a dark navy blue that shimmers almost purple. The thumping speakers are surprisingly good, too.
Apple MacBook Pro 13-inch with Retina Display (2015)
Not only does the 2015 MacBook Pro 13-inch with Retina display last more than an hour longer than the 2014 model — 12:04 versus an already-excellent 10:44 — but it's also a lot more powerful. Plus, a new Force Touch trackpad can sense pressure, letting you do more things with fewer clicks.
Dell XPS 13 (non-touch)
Not only did Dell manage to fit a 13-inch display into an 11-inch, 2.6-pound chassis, but it also squeezed in enough juice to last nearly 12 hours. (The touch version, which has a quad HD display, made it 7.5 hours). Add to that a Core i5 processor, 128GB SSD and 8GB of RAM, a backlit keyboard and a smooth touchpad, and you’ve got one of the best ultraportables of the year.
Asus Transformer Book Flip TP200SA
With nearly 11 hours of battery life, Asus' Transformer Book Flip TP200SA is the second longest-lasting 2-in-1 on this list, and at $349, it's one of the least expensive. But just because it's affordable, that doesn't mean it's cheap. The TP200SA has solid build-quality with its brushed-metal lid; a bright, colorful, 11.6-inch display; and a sturdy hinge that accommodates a wide range of modes. And its Intel Celeron CPU delivers good-enough performance for those on a budget.
Toshiba Chromebook 2 CB35
Not only does it have one of the longest-lasting batteries we've found in a Chromebook, but the Toshiba Chromebook 2 also has an impressively bright and accurate 1080p display. Its keyboard is one that all notebooks should aspire to, and its sleek deck has the look of a more expensive laptop.
Asus Zenbook UX305
One of the best bargains when it comes to long-lasting notebooks, the UX305 starts at just $700, yet lasts more than 9 and a half hours on a charge. Plus, it boasts a slick half-inch-thick aluminum body, Intel Core M CPU, and a 256GB SSD. We wish it had a backlit keyboard, but that’s a small sacrifice at this price.
HP Spectre x360 13t
A gorgeous, 13-inch 1920 x 1080 touch screen doesn't stop HP's sexy 2-in-1 laptop from lasting a strong 9 hours and 28 minutes. During that time, you'll be able to bend the Spectre x360 13t's sleek aluminum lid back to put it into tablet, tent or presentation modes while enjoying the speed of its 256GB SSD and Intel 5th Generation Core Series processor.
Apple MacBook Air 11-inch (2015)
Apple's least expensive notebook, the 11-inch MacBook Air, packs a Core i5 processor and fast flash memory, and lasts nearly 9 and a half hours on a charge. This $899 ultraportable weighs less than 2.5 pounds, too, making it well suited for students and those who want to leave their charger at home.
Asus Chromebook Flip
Lasting more than 9 hours on a charge, the sub-2-pound Chromebook Flip is a 10-inch hybrid that you can take anywhere. For $249, you also get an attractive aluminum design and a bright IPS display. Plus, with new Chrome OS features — including Google Now for voice searches, a touch-screen keyboard and the ability to run Android apps — this device can replace both your laptop and your tablet, if you don't mind a small 10-inch screen.
MacBook Pro 15-inch with Retina Display (2015)
It's not just the crisp 2880 x 1800 display, AMD Radeon R9 R9 M370X GPU or Force Touch track pad that impresses us about the MacBook Pro. We also love that you can get 9 hours of battery life from this 15-inch system, which also packs a 2.5-GHz 4th-generation Intel Core i7 processor and 16GB of RAM. The price you pay ($1,999 starting, $2,499 as reviewed) isn't cheap, but it's worth it.
Acer Chromebook 15
The first Chromebook with a 15.6-inch 1080p display, the Acer Chromebook 15 also shines for its long battery life. Plus, its fifth-generation Intel Celeron processor and large speakers mean that you'll be able to stream movies smoothly, and hear all the dialogue easily. At $350, it's a bargain.
