10 Tablets with the Longest Battery Life

longest lasting battery tablet march16Even the sharpest and most powerful tablets are useless if they can't handle hours of Web surfing, gaming, video streaming and — yes — work. That's why we've compiled this list of the longest-lasting slates. Every slate on this list lasted at least 10 hours on the Laptop Mag battery test, which consists of continuous Web surfing over Wi-Fi with the brightness set to 150 nits. If you need a tablet that can last as long as your Netflix binge session or workday, start here.
Lenovo Yoga Tab 3
15 hours: That's the kind of all-day battery life people have been dreaming of since forever. Lenovo's Yoga Tab 3 has it, and as such, might be the best mobile media tablet on the market. Its 8-inch screen is relatively bright, and Lenovo's tablet even comes with a built-in kickstand. The extra-large battery results in a bigger-than-normal design, and the Snapdragon 212 processor can feel a little lethargic at times, but if you're all about watching movies and surfing the Web, the Yoga Tab 3 can go all day.

Lenovo Yoga Tablet 2
The 12 hours and 37 minutes of battery life is a good reason to love the Lenovo Yoga Tablet 2, but it's not the only one. This 10-inch Android 4.4 KitKat tablet sports a built-in kickstand and curved edge that allows you to use the tablet in multiple modes. The front-facing speakers positively boom audio at you, and the $269 price tag is nothing to sneeze at. Plus, on the software front, Lenovo adds a quick-settings menu called Bottom Switch, which gives you easy access to various settings.

Lenovo Tab 2 A10
The epic 12 hours of endurance from the 10-inch Lenovo Tab 2 A10 is just the beginning of what we loved about this tablet. The Editors' Choice winner also sports a beautiful display and an attractive shell, and it only costs $179. We also appreciated its strong performance overall.

Lenovo Tab 2 A8
Judging by the low $129.99 price tag on the Lenovo Tab 2 A8, you probably wouldn't expect to see it on our list of longest-lasting tablets. That's all the more reason its 11-hour-and-32-minute battery life is both memorable and impressive. Running a close-to-stock installation of Android 5.0 Lollipop, the device also features a very bright HD (1280 x 800-pixel) display that's great for watching videos and browsing the Web.

HP Elite X2 1011
The 11.6-inch HP Elite X2 isn't only a tablet. It can also function as a laptop, if you attach the keyboard. The keyboard has its own battery, which helped this device last for a whopping 11:24 on a charge. This 2-in-1 can take a beating, it comes with some extra security features, and it sports a bright and accurate screen.

Google Pixel C
Google's 10.2-inch Pixel C features a powerful Nvidia Tegra X1 processor and a brilliant display, and it lasts a phenomenal 11:08 on a charge. Add the $149 keyboard to make it more productivity friendly. Android 6.0 isn’t the most productivity-friendly OS, but this tablet has serious staying power.

Apple iPad mini 2
Apple's iPad mini finally has a Retina display, and it's just as good as you'd imagined. But what you may not have expected from this iOS 7-powered slate is that it would get a crazy long 11 hours and 6 minutes of battery life over Wi-Fi. Like the iPad Air, the iPad mini with Retina display features Apple's new 64-bit A7 processor, making this one screaming fast slate.

12.9-inch Apple iPad Pro
While many Windows tablets and 2-in-1s sacrifice endurance for power, the iPad Pro offers a better balance of battery life and speed. This 12.9-inch slate lasted for more than 10 hours on the Laptop Mag Battery Test. The iPad Pro isn't cheap, and it won't replace your laptop, like a Surface can. But the iPad Pro's A9X processor; crisp, 5-million-pixel display; and optional Apple Pencil and Smart Keyboard make it a versatile device that can go the distance.

9.7-inch Apple iPad Pro
As our favorite overall tablet, the 9.7-inch Apple iPad Pro has a lot going for it. Not only does it feature a stunning True Tone display in a sleek design (now in Rose Gold), but it also lasts for 10:53 on a charge. The 12-MP camera is particularly impressive, due to its ability to shoot 4K video. The A9X processor inside is powerful enough to edit those clips, making this a pretty powerful tablet.

Samsung Galaxy TabPro S Review

The Samsung TabPro S tries to do two things really well: immersive entertainment and effortless productivity. This 2-in-1 rocks at the first thing and does moderately well with the second. Users of this $899 Surface Pro 4 foe will enjoy its lightweight design, gorgeous Super AMOLED display and decent performance. The shallow keys and minimal port selection prevent the TabPro S from being a great laptop replacement, but if you're looking for a superthin hybrid for work and play, this is an attractive option.
Update 3/28: We tested the TabPro S's fast-charging battery. Our results are in the Battery Life section. Also, construction materials were changed in the Design section to reflect incorrect information.

Design

With its thin display and sleek case, the Galaxy TabPro S earns points for style. The tablet's polycarbonate body and aluminum edge feel solid and suggest a reliable build quality. Its detachable keyboard is made of a leatherlike material. I liked the stylish grain design on the back and the smooth finish on the notebook's deck.
Samsung Galaxy TabPro S
This magnetically detachable keyboard works in the same manner established by Microsoft's Surface notebooks, meaning it can sit in two positions. I had a hard time snapping the display against the case's flap at first, but I quickly got over the learning curve. The TabPro S's wide, folded keyboard-cover enables users to type in their laps, but the device wobbled in that position.
Samsung Galaxy TabPro S
On its own, the tablet is only 0.25 inches thick, which makes it thinner than the Dell XPS 12and HP Spectre x2 (both 0.31 inches), the Lenovo Miix 700 (0.35 inches), and theMicrosoft Surface Pro 4 (0.33 inches). If you compare the 2-in-1s with their keyboards attached, the TabPro S (0.57 inches) is about as thick as the Spectre x2 and Miix 700, but thinner than the Dell XPS 12 (0.63-0.99 inches). The Surface Pro 4 with its Type Cover is even thinner (0.43 inches).
Without its keyboard, the TabPro S weighs 1.52 pounds, which is slightly lighter than those competitors, whose weights range from 1.7 to 1.87 pounds. When each has its keyboard attached, the TabPro S (2.35 pounds) is slightly lighter than its competitors, which weigh between 2.37 pounds and 2.68 pounds.

Ports

Samsung gave the Galaxy TabPro S only a minimal number of ports. Sadly, this means no SD memory reader, an option found on all of the TabPro S's competitors. Since this 2-in-1 lacks a dedicated power port, users will rely on the notebook's USB Type-C connector to draw power, the only port on the device, save for its headphone jack.
Samsung Galaxy TabPro S
While there are no splitter cables that allow you to charge the computer and use the port at the same time, you can buy adapters from Apple ($79) and iLuv ($60) that enable you to power the computer and use standard USB and HDMI ports.
The colorful Super AMOLED display on the Galaxy TabPro S makes it a compelling companion for watching video.
The port uses USB-C 3.1, not Thunderbolt 3, but is still capable of powering monitors, a big plus of the Type-C standard.

Display

The Super AMOLED display on the Galaxy TabPro S delivers vivid colors and clear details, making it a compelling companion for watching video. When I watched the 4K Interstellar movie trailer on the tablet's 2160 x 1440-pixel screen, I noticed the beads of sweat on Matthew McConaughey's forehead and the grain of the dust that coated his pickup truck. While the panel did a good job rendering the inky black depths of space, and making rich oceans and fiery blazes pop, it suffered trying to reproduce a white sky, adding hints of blue and yellow.
Samsung Galaxy TabPro S
According to our colorimeter, the TabPro S's display can produce up to 180.2 percent of the sRGB color spectrum. That's more than the average mainstream notebook (83.1 percent), XPS 12 (114 percent), Spectre x2 (72 percent), Miix 700 (113.1 percent) and Surface Pro 4 (100 percent).
The Samsung didn't fare as well on the Delta-E test for color accuracy (where closer to zero is best). It notched a score of 4.7, compared to the near-perfect Spectre x2 (0.7) and Surface Pro 4 (0.4).
We wouldn't recommend typing a term paper or long report on the TabPro S. Doing so will not end well.
The TabPro S's display can emit up to 341 nits (a measure of brightness), which beats the Spectre x2, Miix 700 and category average. The XPS 12 and Surface Pro 4 shine brighter. The detachable offers excellent viewing angles, as I observed colors staying intact at 80 degrees to the left or right.

Keyboard, Touchpad and Touch Screen

The TabPro S's keyboard is fine for writing emails, entering URLs and posting quick social-networking updates, but I wouldn't write a report or term paper on it. Doing so will not end well. I started this review on the TabPro S's keyboard cover, but I stopped within minutes, because the keys were so shallow that I constantly bottomed out, forcefully hitting the deck. This is caused by the keys whisper-thin 0.95 millimeters of travel and the overly sensitive 47 grams of force required to actuate. We prefer keys with between 1.5 to 2 mm of travel that require at least 60 grams of actuation force.
Samsung Galaxy TabPro S
The keys are also too closely spaced, leading me to a ton of errors throughout my testing. On the 10Fastfingers.com typing test, I clicked my way to 59 words per minute with only 80 percent accuracy, which is below my 80-wpm, 99 percent average. Most detachable keyboards aren't great, but the latest Microsoft Type Cover (which costs an extra $130) features a chiclet layout that gives its keys some breathing room and makes typing easier.
The Galaxy TabPro S's 3.4 x 1.7-inch touchpad is shorter than those found on the competition, and I missed that extra space as my fingers slid off the edge of the pad. The touchpad has a good feel to each click and accurately registered my input as I navigated the desktop, but it was slow to recognize three-finger app-switching gestures.
The touch-screen display is also a little slow on the TabPro S, as I saw it lag behind my digits when I doodled in MS Paint and performed pinch-and-zoom gestures in Chrome.

Audio

The Galaxy TabPro S's small stereo speakers produced results that beat my expectations. Set at 100, the tablet filled a medium-sized conference room with an accurate but underwhelming rendition of A Tribe Called Quest's "Buggin' Out." The beat's bass reverberated well, the group's vocals sounded clear, and high-hat drums came out crisp.

Performance

The Galaxy TabPro S may not be a speedy workhorse, but it offers enough oomph for basic multitasking. The 2-in-1 is armed with an Intel Core M3 processor, 4GB of RAM and a 128GB SSD. I encountered no lag when I split my screen between a streaming 1080p video and a dozen Chrome tabs, including TweetDeck, a Google Doc and Gmail.
Gamers looking for an extra monitor for Xbox play will find that the TabS Pro offers a good second-screen experience.
Gamers looking for an extra monitor for Xbox play will be happy that the tablet provides a good second-screen experience. When I streamed Killer Instinct from our office Xbox One onto the TabPro S, there was no lag between my taps on the controller and Fulgore's hacks and slashes. This doesn't tax the laptop's CPU, but rather its 802.11a/b/g/n/ac modem, which performed like a champ.

It wouldn't be a fair fight to put the TabPro S's Core M3 processor up against the M5-powered Lenovo Miix 700 and Dell XPS 12, the M7-powered HP Spectre x2, or the i5-powered Microsoft Surface Pro 4. The Intel chip Samsung included isn't designed to be that powerful, which explains the TabPro S's relatively low score of 4,675 on the GeekBench 3 general performance test. The above detachables scored in the 4,875 to 6,811 range. Still, the TabPro S never left me waiting for it to process a task or command.

The TabPro S's SSD drive did a better job, copying 4.97GB of files in 45 seconds for a rate of 117.7 MBps. That beats the solid-state drives in the XPS 12 (82.1 MBps) and Miix 700 (96.7 MBps). We found faster storage in the SSD-equipped Spectre x2 (149 MBps) and Surface Pro 4 (318.1 MBps).
The Samsung 2-in-1 recorded an OK time on the OpenOffice macro test, taking 5 minutes and 45 seconds to match 20,000 names and addresses. That's shorter than the ultraportable average (7:24) and the Miix 700 (both 5:59), but longer than the Spectre x2 (5:34), XPS 12 (5:14) and Surface Pro (4:11).

Graphics

The closest thing to hardcore gaming you can do on the TabPro S is with the aforementioned Xbox streaming. Armed with integrated Intel HD 315 graphics, the TabPro S is limited to casual gaming such as the preloaded Candy Crush Soda Saga and racing titles like Asphalt 8, which played smoothly on the machine.
On the 3DMark Ice Storm Unlimited gaming benchmark, the TabPro S earned a score of 51,305, which beats the ultraportable average (44,613), XPS 12 (46,364) and Miix 700 (21,995). The Surface Pro 4 (60,424) and Spectre x2 (52,450) did better than the TabPro S.

Heat

Like most detachable 2-in-1 notebooks, only the TabPro S's tablet display warmed up. After we streamed 15 minutes of HD video, our heat gun registered a temperature of 95 degrees Fahrenheit on the bottom of the display, which matches our comfort threshold (95 degrees). The notebook's keys and trackpad both stayed cool, measuring 75.5 degrees. 

Cameras

The tablet's 5-MP front and rear cameras captured clear and accurate images inside and outside of our office.
The camera on the tablet's backside did a good job reproducing the colors of the petals and green bush on our rooftop, and the red of the Purch wall looked accurate in a selfie I took in front of it.
The TabPro S's rear camera can also shoot 1080p video at 30 frames per second.

Battery Life

While the Galaxy TabPro S has longer battery life than other detachables, it doesn't offer enough to last the day. On the Laptop Mag Battery Test (constant Web surfing over Wi-Fi at 100 nits of brightness), this 2-in-1 lasted 6 hours and 46 minutes. That's better than the XPS 12 (5:17), Spectre x2 (6:31) and Surface Pro 4 (6:05) but still far short of the 8-hour average for all ultraportable laptops.

Samsung claims the tablet can receive a full charge in only 2.5 hours via its Adaptive Fast Charging wall charger. Our tests prove this to be near-accurate; our TabPro S's battery went from non-functional to 96 percent in that time.

Software

Samsung has given the Galaxy TabPro S a mostly pristine installation of Windows 10, only adding a few proprietary utilities. Samsung Recovery gives users a data backup and factory-restore options, and Samsung Update provides an easy way to download software updates from the company.
Samsung Galaxy TabPro S
Although it was not available during testing, a feature called Samsung Flow will enable owners of Galaxy mobile devices to unlock the 2-in-1 with their phone or tablet's fingerprint scanner and receive notifications from that device on the TabPro S.

Bottom Line

The TabPro S offers a vibrant Super AMOLED display and decent performance for less than a grand, with the best battery life of any detachable we've tested this year. However, this hybrid is a better tablet than it is a laptop, because of its shallow keyboard and a display that can wobble in your lap. Plus, you'll have to be willing to sacrifice a full-size USB port and memory card slot.

If you want a better typing and pen experience, we recommend Microsoft Surface Pro 4with optional keyboard ($1,029). The Dell XPS 12 (starting at $1,000) is better for using in your lap, but its battery life is worse than that of the TabPro S. Overall, it's best to think of the TabPro S as a great Windows 10 tablet that can double as a notebook.
  • Pros /

     
    Beautiful Super AMOLED display; Very thin, lightweight design; Solid multitasking performance for price
  • Cons /

     
    Shallow keyboard; Tablet wobbles in its case; Paltry number of ports
  • Verdict /

     
    The Samsung Galaxy TabPro S is a stylish, 12-inch, detachable 2-in-1 with a beautiful display and OK performance, but its keyboard needs work.
