Phones with best battery life 2019 - buyer’s guide

GSMArena team, 22 Nov 2019.

Fast charging has been getting faster and more widely available even on more affordable smartphones. Still, while being able to top up a phone in less than an hour, or even half an hour, can lead to changing your charging habits entirely, actual battery autonomy remains a key priority - no VOOC can help you out when there's no power outlet around.

So on this page you will find the phones that prioritize battery life and scored at the top of our battery testing chart.


Editors' choice

Asus Zenfone 6 ZS630KL

Asus Zenfone 6 ZS630KL

Specs
  • 112h Endurance rating (36:22h calls, 15:42h web, 16:07h video)
  • Super cool rotating camera means selfies are as good as main-camera photos, plus you can have ultra wide selfies
  • Excellent camera quality overall in both stills and video, stabilization is good too
  • Top-tier chipset, flagship-grade performance
  • Dedicated microSD slot
  • Slow charging (2:32h to full, 35% in 30mins), no wireless charging
  • No telephoto camera
  • Possible reliability concerns over the moving bits

Our top pick for a battery life champ is the Zenfone 6 for managing to deliver excellent endurance while packing a high-end chipset.

The Zenfone has a 5,000mAh battery, which was one of the highest capacities back when we reviewed it. It aced our battery tests, delivering balanced results across the board and, perhaps more importantly, did that with a flagship Snapdragon 855 chip - the top-tier SoCs don't normally go to the top our battery life charts. We can only imagine what could have been if Asus had fitted a more efficient OLED display instead of the somewhat dim LCD.

The flipside to the big battery is that in a land where the fastest solutions take half an hour to charge from 0 to 100%, the Zenfone 6 needs 5 times that. Ah, but priorities - Asus preferred to go for long battery longevity over fast charging.

Mind you, alongside the high-end silicon, the Zenfone has a very capable camera setup (albeit lacking a telephoto) for both stills and video. And the fact that it's a flipping module that turns 180 degrees to face the front is not only cool, but also means you'd get some of the best selfies in the business and you can even have ultra wide-angle ones.

Samsung Galaxy M30s

Samsung Galaxy M30s

Specs
  • FullHD 6.4" Super AMOLED display
  • 6,000mAh battery makes a promise we know it'll keep
  • Gaming-friendly Exynos 9611 chip
  • Capable camera setup
  • Dedicated microSD slot
  • Plastic build, back is a fingerprint magnet
  • The 15W charger will take a while to top up the M30s - you'll be better off sticking to overnight charging

It may be counter-intuitive and come as a surprise to you that we have a phone we haven't reviewed in our shortlist for battery life. The thing is though, we have seen our fair share of Samsungs with Super AMOLED displays and Exynos chipsets to know to a comfortable level of certainty that the M30s will, indeed, deliver superb numbers for longevity.

Add to that general data the more specific facts that the M30s comes with the same display and essentially the same chipset as the already long-lasting A50, but adds 50% more capacity, and we're looking at one of our potential all-time battery life champs. What's not looking so rosy is the charging situation - maxing out at 15W, the M30s is mostly an overnighter.

Specs
Xiaomi Redmi Note 8 Pro

Xiaomi Redmi Note 8 Pro

Specs
  • 114h Endurance rating (33:28h calls, 15:06h web, 15:25h video)
  • Mediatek chipset is snappy and efficient
  • 64MP main camera does admirably, selfies are really nice too
  • Great video quality overall
  • Slow charging (39% in 30mins), no wireless charging
  • The macro and ultrawide cameras are uninspiring
  • Video recording in 1080p leaves more to be desired

Next on our list is the Redmi Note 8 Pro. With almost identical numbers to the Zenfone for endurance, the Redmi comes at a bargain price for its hardware and performance. It packs one of the largest smartphone camera sensors available and extracts great output out of it in both stills and video. And its Mediatek chipset has nothing to be ashamed of in the company of Snapdragon 730s and such.

As seems to be the norm in this category, the Redmi Note 8 Pro isn't quick to fill up that battery once it's depleted. Oh, well. It's also not universally great in its imaging department, but it's more than just good enough for the money.

Realme 5

Realme 5

Specs
  • 144h Endurance rating (47:12h calls, 21:11h web, 20:02h video), ideal for heavy talkers
  • Excellent performance, great for gaming
  • Very good photos out of the main camera for the class
  • Dedicated microSD slot
  • Low-res display (big, though, if that's your thing)
  • Limited regional availability
  • Uninspiring macro and ultra wide cameras

Moving down the ranks, we're getting to the Realme 5. While not universally available, this budget Realme is one of the best options for long battery life where you can buy it. It's particularly amazing for voice calls, but 20 hours in each of our screen-on tests is even more impressive. Mind you, the Snapdragon 665 that's at the helm isn't too shabby either and is actually quite the performer even for gaming.

What does help is the display's lower resolution - 720p at 6.5 inches makes for a lowly density by today's standards. But to fit all this battery life, performance and, come to think of it, image quality, into the Realme 5's price, a trade-off had to be made somewhere, and it's not an unreasonable one.

Motorola Moto G7 Power

Motorola Moto G7 Power

Specs
  • 147h Endurance rating (42:52h calls, 21:45h web, 23:58h video), ideal for heavy talkers
  • Very good camera experience in daylight and 4K video capturing
  • Has splash resistance
  • Modest chipset, not well suited to gaming
  • Single camera on the back, what year is it?
  • If you're not hell-bent on battery life, more value can be found elsewhere

Another marathon runner, the Moto G7 Power has to cut more corners to get those numbers. For one, it relies on a more unpretentious chipset, making it a poor choice for gaming. It's not particularly cheap either for what it offers outside of endurance.

We've established you're here for the endurance, however, and that it does deliver. It's also got a very nice primary camera that takes nice photos and 4K video. Did we say 'primary'? No, there's actually just one camera on the G7 Power's back - bummer.

Fastest charging

Oppo Reno Ace

Oppo Reno Ace

Specs
  • Fastest charging we've seen - the 65W adapter takes it from 0 to full in 28 minutes
  • 99h Endurance rating (30:23h calls, 12:15h web, 21:02h video)
  • 90Hz display is super smooth, and also plenty bright
  • Very good camera experience in all conditions, particularly good portraits
  • Excellent stabilization all the way to 4K60
  • As with all proprietary solutions, the super fast charging requires all the links in the chain - phone, cable and adapter
  • Noisy stills and video when looking up close
  • Benchmark performance on the low end of the spectrum for the hardware
  • Limited regional availability

Even though we prefaced this list insisting that endurance beats fast charging, we can't not mention the Oppo Reno Ace - the fastest charging phone we've had at the office. Topping up its 4,000mAh in less than half an hour it makes overnight charging a foreign concept. That is, if you always have the proprietary peripherals on you when you need to top up fast.

Mind you, the Reno Ace also has more than enough battery life to begin with, so it's not like you'll be charging it very quickly, only twice a day. It's a plenty good phone all around too, with a bright 90Hz display and a really capable camera that stands out with particularly awesome video stabilization.
