You Want a Tablet That Goes On, And On, And On
This page is all about battery life and its importance, but first here’s a table that shows tablets that give at least 8 hours of battery life and were rated highly by our reviewers.
Good Tablets with Good Battery Life
- Take note of the release date – an older tablet may have gotten a good review when released but struggle to cope with modern games or web browsers.
- Bat cap means battery capacity, measured in mAh.
A tablet computer is now much more than just an entertainment device. As organizations and government agencies adopt mainstream tablet usage, the demand for efficient hardware components such as the battery has become really important.
Consumers now take it for granted that a tablet computer or phablet will have at least 6.5 hours of battery life with heavy use – and the single biggest complaint about mobile devices is how soon they run out of juice.
Apple iPad Mini 4
The iPad mini remains a small tablet that has very few competitors on the market, even after all this time since it was released. The efficiency improvements in this variant hold it ahead of its rivals, and for most individuals, iOS 9 is now well ahead of Android as a tablet operating system. The performance of iOS third-party apps, especially those specifically intended for iPads, makes it a general superior option.
In terms of battery life, this is one of the finest tiny tablets that you can choose. If you are after a medium-sized device not a mobile, not a big tablet, and you also want a long-lasting battery, this is an excellent choice. The iPad mini 4 in the rundown test returns a period of 10hrs 43mins. It’s not as great as the Samsung Galaxy Tab S2 8 in’s 14hrs 7mins, but ten hours is good by any norms, particularly as Apple has lowered the battery capacity here from 6,350mAh in the iPad mini 3 to 5,124mAh. (Note that we altered the brightness to better match typical usage by setting the display from 120cd / m2 to 170cd / m2. This is an awesome tablet to buy for someone who wants to read, listen to music, watch videos and play lightly.
Lenovo Yoga 2 10″
For some of the other top devices on the market, the Yoga 2 from Leovo is strong, but not quite a the best match. It runs together with 2 GB of RAM on a quad-core Intel Atom Z3745 processor clocked at 1.86GHz. It’s a tablet that can blitz through daily functions like browsing the internet, writing messages and watching films or media consumption. To manage complicated 3D games, it is strong enough but not the best. Games like Asphalt 8, Dead Trigger 2 and Real Racing 3 can be played smoothly and beautifully. There are no problems with overheating either. During especially intensive use, the rear warms up a bit, but it never affects performance.
Lenovo has not disclosed the battery capacity contained within that distinctive bulge, but argues that it can withstand up to 18 hours of blended charging. The Yoga fell from complete to void in 10 hours and 48 minutes while watching YouTube clips with the display set at 80% color and quantity at 40%. This is a nice outcome, and it’s easy to get blended use on a single cost for a few days. It’s not the fastest charger in the globe, though. At the socket, 30 minutes will restore 13% of its battery, which would provide 84 minutes of use theoretically. It requires five hours for a full charge.
Samsung Galaxy Tab A 9.7”
The Samsung Galaxy Tab A 9.7 is a good tablet with consistent results and a truly contemporary layout. Its plastic construction provides it a little bit of a costly feel, but it doesn’t look like a cheap item of hardware; the charcoal-gray back panel shimmers mildly in the sun and its soft texture gives it a sleekly streamlined shape. This variant of the Tab A is a full-size phone with its 9.7-inch display, but not an overly large one. It arrives in at 9.6 x 6.6x 0.3 inches and 1.1 lbs., which implies that for hours it is small and fast enough to be used comfortably. The lunettes on either hand of the display are slim, but they are broad enough to keep the tool in portrait mode.
The average of 15.7 hours is simply amazing for the Tab, when it comes to battery life. Compared to other tablets in its category, it scores a lot better and seems to be much more efficient. This tablet has a battery of 6000 mAh, which Samsung claims is great for up to 14 hours of video viewing or up to 15 hours of web surfing. These are incredibly elevated battery life figures, but we can verify that coupled with an undemanding processor, this tablet’s comparatively big battery allows it to go on a single charge for many hours.
This device still had a 65% charge after a complete working day of very intensive use, with constant Wi-Fi and Bluetooth links. The Tab A 9.7 lasted five days before being plugged in in when used lightly.
Lenovo Yoga Book
At first look, the Yoga Book feels like any other computer of Lenovo Yoga–only narrower. The amazing, beautiful watchband hinge first implemented with the Yoga 3 is present and accurate, and the insane slender unit is covered in a soft, luxurious magnesium alloy frame like so many Yoga machines before it. The 10.1-inch, 1,920 x 1,200 resolution display, despite its dimensions. HD films look great on the Yoga Book with 400 nits of brightness and the ability to show a variety of 16.7 million colours, and in-plane shifting (IPS) implies wide angles for screen sharing.
What will certainly please every Yoga Book consumer is the long battery life of the tablet. Lenovo argues that the tablet with its whopping 8,500mAh battery is great for up to 15 hours of continuous use. Of course, supplier predictions scarcely, if ever, align with the outcomes of the real world, but the longevity of the Yoga Book is remarkable nonetheless.
Although we haven’t carefully checked the battery life of the Android version, we see that after 4 hours it loses about 50% of its ability. So, expecting about the same battery life as we see from the Windows model here is safe. You can expect the Yoga Book to last for a whole day worth of use, almost regardless of the task.
iPad Pro 10.5-inch
If you want an Apple tablet that balances entertainment, efficiency and a sleek 10.5-inch shape factor, the iPad Pro 10.5 is the finest iPad you can purchase. With the iOS 11 tablet-focused update, switching applications is simpler, even if it’s not quite a MacBook touchscreen. It’s near that. Also an audio visual treat is the fresh display with thicker bezel and strong speakers. The 10.5-inch iPad Pro is Apple’s decision to create a tablet with totally everything in it. This tablet is the greatest in video quality, the cream of the company’s mobile screen software, and all the energy inside a digital slate’s metal walls that can be crammed.
Well, the battery life of the 10.5-inch iPad Pro depends pretty much on what your activity is.
If you’re just going to leave it in a bag for days at the end, pulling it out for a word processing spot or the odd movie, you’ll easily get a single charge worth a week’s standby.
You’d have to ask, though, why would anyone invest so much cash on a tablet like this and then just use it a few times a week. Where it really shines is like a substitute for a computer–and that’s where the battery life is a little more difficult to quantify. So if you’re talking about using this as a laptop substitute then you’re likely going to look at about 6-7 hours of use on a single charge (based on how much you use it).
Here’s a huge list of tablets that should give at least 8 hours of charge:
Tablets with Good Battery Life
The race for the longest battery life has become as important as that of the fastest processor, bigger RAM or higher screen resolution. This page will help you understand some of the key characteristic of tablet batteries and if these little details should influence your tablet purchase.
Battery specs vary between manufacturers. At first, it may seem a little confusing, but there are a few details you need to watch out for. Battery capacity is simply the amount of charge a unit can store – something like the fuel capacity in your car.
It is usually measured in Ah or Ampere Hours. However, in the case of tablets, most manufacturers rate in mAh or milli ampere hour. For example, the Samsung Galaxy Tab 10.1 battery is rated 7000 mAh. The battery is likely to last a lot longer with higher mAh so when using our charts to compare by capacity, higher is better.
In addition to mAh ratings, most manufacturers also provide additional battery consumption information such as video play, audio play back and standby time.
Continuing with the same analogy of a car and its fuel capacity, your car is likely to have better mileage if you drive it on lower revs, accelerate and brake smoothly. Similarly, your tablet computer’s power consumption is directly dependent on how power hungry the various components in your tablet are.
While manufacturers’ power ratings are a good indication of how long the battery will last, you may also need to adjust screen brightness, reduce the volume, close the number of apps running in the background, change settings for syncing (and so on) to maximize your tablet’s battery life.
Battery Life Benchmark Tests
Most battery life tests will involve running videos continuously at bright screen settings or running a graphics-heavy game till the battery dies. Depending on the reviewer, there will be different methods of doing the tests and different results.
In our reviews we take into account our own experience of the device, plus the maker’s specs, and results from others in the industry. We try our best to be accurate, but some variation is inevitable.
Battery Care – How to Improve Battery Life
Calibrating your tablet battery is one of the most important steps to ensuring longer battery life. Check your tablet manufacturer’s documentation to see if there are any recommended methods of calibration.
Battery calibration and maintenance techniques will vary depending on whether the battery is made of lead acid, lithium ion or nickel base. One of the most popular and effective ways of calibrating your battery is to charge and discharge the battery completely the first few times and then ensure that you discharge the battery completely at least once every three months.
Once the tablet is completely charged, do not leave the charging cable connected to the tablet. As far as possible, keep the tablet in its ideal operating temperature range as it will help keep the battery performing at optimum levels.
Having said that, many people have their battery plugged in to a charger most of the time and don’t suffer any loss of battery performance as a result. It’s probably better to have the battery charged ‘too much’ than to let it go to zero too often.
Apple has a guide about maximising battery performance here.
There’s an app called Greenify that many people had a good experience with. Try it out!
Further tips for Android users include:
- use dark screen backgrounds
- turn off vibrate and haptic feedback features
- never use third-party (i.e. suspiciously cheap) batteries
- turn off wifi, 4G etc when not needed
- turn off auto-sync
- don’t use auto-brightness
- don’t keep your tablet in a hot place
- if you aren’t going to use your tablet in a while, let the battery level fall to about 40%. That’s ideal for long-term storage.
- recent evidence suggests one of the worst battery hogs is the Facebook app – try uninstalling that for a few days and see if you can notice the difference. Some users are reporting 20-30% savings just from that one trick.
Can You Use Your Tablet While It’s Charging?
Yes, it’s completely safe to do so. If you’re running something that demands a lot of power, like a 3D game, your tablet might start getting hot. If that happens, use your common sense: either unplug the charger or stop the game for a while.
