5 Work Laptops With 12+ Hours of Battery Life

Work laptops

For some small business owners, long battery life is the single most important feature a work laptop can have. If you're one of the many entrepreneurs who work long days, often away from a power source, and want a laptop that works as long and hard as you do, this list is for you.

Editor's Note: Microsoft recently announced the release of the Surface Book 2, which is available with a new 15-inch screen, improved specs and a claimed battery life of 17 hours. It starts at $1,499 and will be available for pre-order on Nov. 9. We have not tested or reviewed the Surface Book 2 yet, but when we do we may update our recommendations here. 

 

The Lenovo ThinkPad T470 is a sturdy, powerful work laptop with a superb battery life of more than 17 hours. This laptop was built for business in every way possible, from the comfortable keyboard and sensitive trackpad (and signature bright red TrackPoint pointing stick) to the variety of ports and zippy seventh-generation Core i5 CPU. If you want a classic business workstation that can go the distance, you'll like the ThinkPad T470. The only downside to this work-marathon machine is its weight; at 3.49 pounds, it may be a bit too heavy for frequent travelers 

 

 

 

Mac lovers who need extended battery life should check out the MacBook Air 13-inch. While we don't typically recommend older laptop models (this MacBook debuted in 2015), the MacBook Air 13-inch is still on the market and fully supported. It offers real value for money, relative to other Mac laptops, and of course, it loves the MacOS. The battery lasts up to 14 hours on a charge. It sports a solid Intel Core i5 processor, and the luxe look and feel you expect in a Mac.  

 

 

With a full-sized keyboard and that classic Lenovo business look, the ThinkPad X270 is a more portable and lighter (2.98 pounds) alternative to the ThinkPad T470 (3.49 pounds). Despite its lighter weight and more compact size, the ThinkPad X270 has enough power for serious business users, plus an impressive 13.5-hour battery life. The entry-level model is surprisingly affordable at just $881.10, but like all Lenovo machines, it can be decked out and upgraded as much as you like. If you need a little more power or RAM, you can customize that into your machine (for a price).  

 

 

The Dell Latitude 7280 is a bit more expensive than the Lenovo machines on this list, but it also sports a slightly more modern design and a lighter chassis (2.61 pounds). The entry-level machine comes with a little less under the hood in terms of processing power (an Intel Core i3 instead of the Lenovo's Intel Core i5), but you can easily upgrade the CPU to something with more horsepower. We measured a battery life of almost 12.5 hours with these specs, so if you're in the market for a long-lasting Dell, you should consider this model.  

 

 

The most expensive long-lasting laptop on our list (it starts at $1,349), the Microsoft Surface Book is also the only hybrid machine that qualified for our battery-life challengeThe design is aesthetically striking and functional, and the unique flexible hinge and ability to unclip the screen from the keyboard is a win for entrepreneurs who want a laptop and tablet in one.  

The Microsoft Surface Book also features the best screen resolution (3000 x 2000 pixels) of any laptop on our list, and it comes with a Surface Pen (you can even store the pen on the book, thanks to a magnetic strip). When you consider all those specialized features and the fact that the Surface Book lasts an impressive 12 hours and 29 minutes, the price tag is, if not in budget, understandable.
