Laptops with the Longest Battery Life

  • MORE

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.

Asus X205

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 i6 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.

    What about the dell chromebook 13?

  • UConnRon Says:

    Chromebooks give the most bang for the buck. Light weight, no viruses, long battery life, automatic upgrades, and low price. I have been using computers (Apples, DOS, & Windows) since 1981. I like my Toshiba Chromebook 2 over all others.

  • lithic Says:

    I have been using the Lenovo Thinkpad T440s for seven months with the 6-cell external battery.

    It just keeps on going - sometimes a whole day in the office with full use(WiFi, full brightness etc.) and there's still charge left in the evenings.

    I've even taken it camping knowing that I would get reliable use for many evenings without recharging (I don't have a second external battery for it because one is enough!).

    I doubt that most, if any, of the other laptops in this review can achieve that, particularly with a 14" screen and a CORE i7 processor.

    That said, despite it's many strengths (for example, the ability to dual-boot Ubuntu without any hassles) I'm wary of Lenovo because of their fickle support and very poor communication.

    I'm buying my second battery for my samsung laptop, and when comparing my current battery to the pictures I see on ebay I'm finding one difference and would like to know if it makes a difference?

    I looked in my history and the last battery I bought had this title: samsung rv520 rc512 rv511 oem genuine battery 11.1v 48wh aa-pb9nc6b ba43-00282a

    On the back of the battery on the white barcode at the top, after the long barcode there is a smaller one and it either says "rev 1.0" or "rev 1.2".

    My current battery says "rev 1.0", do I need to get the "rev 1.0" one or will either work? All the other numbers and codes match up.

    Why is the HP Spectre 13t-3000 not available for purchase anymore? I really have been wanting to buy one of these, and now I see that it is no longer available. I can't seem to find a straight explanation as to why it is completely gone after only being released in Q4 of 2013. Was is recalled? Is a newer model coming out soon? Can I please get a straight answer?

  • Jimmy Says:

    Battery life depends on the size, form factor, and its internal components. But where is the Samsung series 7 Chronos, and the Ativ book 9?

  • Paul Renault Says:

    According to Panasonic's spec sheet, their CF31 has a (with no extra) battery life of 14.5 hours; easily topping the Lenovo X320's "paltry" 7 hours. Adding the media pocket battery brings the total to 21 hours. To me, this is a clear winner in this battle.

    Yes, it is a little heavy, but you don't need to carry it in a big, heavy, padded case - so what if you drop it on the sidewalk, eh?

    Bonus, you can safely use it at the beach in the sun - just rinse it off if you spill your mai tai on it.

  • John B Says:

    Acer 4810T runs 7-8hrs with stock battery. Of course no longer available since this is 3 yrs old but it is the 'John Deere" of computers, IMO. Very satisfied and would suggest that you look at the current replacement of this item in an Acer model.

  • sunny dee Says:

    The best experience I have had is with samsung NC215 notebook.
    It runs for about 8 hours when fully charged

  • Ron B. Says:

    I have a Gateway 18" display. I know it will run for about 4 1/2 hours on a single charge. I haven't tried it much longer.
    My criteria was large screen and at least 3 GB of memory. Hard drive size didn't matter a lot because I don't store a lot of games or many large programs on it. My largest game is Microsoft Flight Simulator and I have an older version of Word and Excel. I don't upgrade unless there's absolutely no way to get around it. By the way, my old laptop died after about 11 years I had to get a new one. My biggest criteria was the ability for wireless connections for my wife and I. We use Comcast and have had no problems with our computers AFTER they came out and buried our phone lines.

  • theEVT Says:

    I think the FatBatt Fifty is a more accurate list. They update it too but I don't know how often.

  • kinesthe Says:

    Given some laptops are tested with sheet batteries, why not test the Dell e6430 with its battery slice as well? Over 30 hours of runtime with its battery slice option

  • freeskydiver Says:

    What settings did you used during the tests??

    Thanks. We'll try to get one in.

  • nando4 Says:

    How about testing a 12.5" HP 2570P with 100Whr 9-cell? It claims 9-15hrs battery life in it's specs. A system with a socketted CPU (so can be user upgraded) and optical drive. A decent alternative to a 12.5" Lenovo X230 which has a soldered CPU and no optical drive.

    Dear Jake:
    Where can I get a monster 18.4″ with discrete graphics cards with the new Sandy Bridge processors ?
    And Hi-Life batteries for geological field work.

  • Jake Says:

    Well battery life depends. If you have a monster 18.4" with discrete graphics cards expectations are alot less. But with the new Sandy Bridge processors your getting then you ever had before.

  • Miss Versatile Says:

    I had the Samsung N110 and I loved the battery life. I could go from JFK airport to LAX including time in airport waiting for flight on one battery charge. During this last CES it was great to have I didn't worry about the battery until end of day. It doesn't take long to recharge from empty battery either. Only downfall is it got hot quickly and was kinda slow compared to other laptops on the market.
