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, which involves continuous Web surfing over Wi-Fi at 100 nits of brightness, we've identified the longest-lasting notebooks on the market. We're talking more than 10 hours of endurance, which should more than suffice for that cross-country flight, a long day of meetings or multiple, back-to-back classes.

Lenovo ThinkPad T470 (17:25)

If you want a truly fantastic keyboard, durable chassis and strong performance, look no further than the ThinkPad T470. The T470 makes room for an optional extended battery that gives this 14-inch laptop over 17 hours of endurance (with its non-touch display). You can charge the laptop over a proprietary ThinkPad connector or via its Thunderbolt 3 port, which allows you to juice the laptop and output to multiple monitors over a single wire. A durable, MIL-SPEC-tested chassis helps this long-lasting business notebook stand up to the rigors of all-day business travel.

Lenovo ThinkPad X270 (13:51)

Weighing 3 pounds (3.4 with extended battery), the 12.5-inch ThinkPad X270 is light enough to carry anywhere and small enough to fit easily on most airplane tray tables. Its 12.5-inch display outputs a vibrant 88 percent of the sRGB color gamut while a snappy keyboard and accurate pointing stick make editing documents a pleasure. Unlike many Ultrabooks, the X270 has plenty of ports, including a USB Type-C connector, multiple USB 3.0 connectors, an SD card reader and an Ethernet connector.

With its extended battery on board, this powerful laptop lasts nearly 14 hours on a charge. If that's not enough endurance for you, you can carry a spare battery and swap it in, without even turning off the computer.

Dell XPS 13 (13:49)

Our favorite laptop overall, the Dell XPS 13 uses a nearly-bezel-free Infinity display to pack a 13-inch panel into a chassis that might otherwise hold an 11-inch laptop. Despite its slim, 0.6-inch thick dimensions and 2.7-pound weight, Dell's laptop offers nearly 14 hours of battery life with its standard, 1080p screen. The touch version, which has a 3200 x 1800 display, lasts over 9 hours on a charge.

Add to that an Intel 7th Gen Core i3, i5 or i7 CPU, a speedy PCIe SSD and plenty of ports and you have the best consumer Ultrabook around. A Killer Wi-Fi card and Thunderbolt 3 charging round out this impressive package.

Dell Inspiron 11 3000 (13:39)

Starting at just $199, Dell's lightweight laptop proves that you don't have to spend a lot of money to get truly epic battery life. This Celeron-powered, 11.6-inch laptop offers just enough performance for web surfing and light productivity. At just 2.4 pounds, the Inspiron 11 3000 is light enough to carry anywhere and, with over 13 hours of endurance, you can leave the plug at home.

The Inspiron 11 3000 is also one of our top choices for kids, because of its small size, low-price and attractive blue and red color options. For better multitasking, we recommended spending $50 over the base price to get a configuration with 4GB of RAM.

Microsoft Surface Book (12:29)

When coupled with its keyboard dock, Microsoft’s detachable notebook will last up to 12.5 hours, provided you buy it with integrated graphics. A 13.5-inch, 3000 x 2000-pixel display is gorgeous to look at and a magnetically attached stylus makes writing a pleasure. Starting at $1,499, the Surface Book is an expensive system, but worth every penny.
