Phones with best battery life 2020 - buyer’s guide

GSMArena team, Last updated 26 May 2020.

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 as fast as 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

Xiaomi Poco F2 Pro

Xiaomi Poco F2 Pro

Specs
  • 120h Endurance rating (36:26h calls, 15:45h web, 25:16h video)
  • 4,700mAh battery, 33W charging
  • One of the cheapest flagships
  • Large uninterrupted OLRD screen, HDR10+
  • Snapdragon 865 chip
  • Versatile camera setup
  • No microSD slot
  • Lacks water resistance

Our top pick for a battery life champ is the Poco F2 Pro for being one of the most powerful smartphones and the most dependable performer when it comes to battery life.

The sequel to the legendary Pocophone has everything a flagship on the budget should pack - a great HDR10+ OLED screen, notch-free at that, the most current Snapdragon chipset, and all sorts of cameras.

But the Poco F2 Pro goes beyond that and has one of the largest batteries that provides the ultimate gaming and/or multimedia experience in one charge.

Sure, there are a few phones that scored better in battery life, but none of those can match the Poco F2 Pro in, well, everything, and then go and offer its impressive battery life for a Snapdragon 865 device.

Realme 6i

Realme 6i

Specs
  • 186h Endurance rating (34:59h calls, 29:59h web, 20:55h video)
  • Very affordable
  • Large screen, splash resistant body
  • Gaming-friendly performance
  • Dependable photo camera
  • Dedicated microSD slot, 3.5mm jack
  • Slow charging (50% in 50mins)
  • Low-res screen
  • No 4K video recording

The Realme 6i beats any other smartphone we've tested to date, but that's probably the best we can say about it.

It's mid-2020 and we're already spotting a trend with new phone releases with extra-large battery capacities on the rise and the Realme 6i is a prime example. It surprised us pleasantly by pushing the ceiling of our all-time battery test chart higher than ever before.

The Realme 6i has a 5,000mAh battery, which is a sizeable battery by any standard. It aced all of our battery tests, delivering remarkable results across the board. It also supports 18W charging - a standout feature within the budget class.

The Realme 6i is a cheap phone with a basic 720p screen Its Helio G80 chip can do for gaming thanks to the low-res screen, but don't expect something spectatular.

Samsung Galaxy M30s

Samsung Galaxy M30s

Specs
  • 130h Endurance rating (35:29h calls, 16:13h web, 21:32h video)
  • FullHD 6.4" Super AMOLED display is excellent overall
  • Efficient and decently powerful Exynos 9611 chip
  • Capable camera setup
  • Dedicated microSD slot
  • Plastic build
  • Iffy fingerprint reader experience
  • Slooow charging (21% in 30mins)

The Galaxy M30s' battery capacity of 6,000mAh makes a promise which the handset keeps in practice - it posted a 130h Endurance rating in our testing. There's a pretty good phone around that battery too - an excellent AMOLED display, well balanced chipset and capable camera combine to make up a really nice package.

What's not looking so rosy is the charging situation - maxing out at 15W, the M30s is mostly an overnighter. We were also not very thrilled about its fingerprint reader and the all-plastic build feels cheap-ish. Some competitors fare better in these respects, though it's hard to beat the M30s for longevity.

Xiaomi Redmi Note 9S

Xiaomi Redmi Note 9S

Specs
  • 127h Endurance rating (41:30h calls, 19:12h web, 16:30h video)
  • Snapdragon 720G chipset is snappy and efficient
  • Great HDR10 screen, even the uneven backlight around the notch
  • Good camera quality overall
  • Dedicated microSD slot, 3.5mm jack
  • Slow charging (1 hours and 45 mins for a full charge)
  • No NFC

Next on our list is the Redmi Note 9S. In addition to the outstanding battery autonomy, it also delivers some excellent bang for the buck making it one of the cheapest gaming-oriented smartphones. It also offers enjoyable stills and videos.

As seems to be the norm in this category, the Redmi Note 9S isn't quick to fill up that battery once it's depleted. And despite it is aimed at global markets, it omits NFC and that will be a bummer for many.

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 low 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, something had to give, and in this particular case, it was the screen.

Motorola Moto G8 Power

Motorola Moto G8 Power

Specs
  • 136h Endurance rating (30:56h calls, 20:23h web, 18:21h video)
  • Okay camera experience in daylight with versatile shooting modes
  • Has splash resistance
  • Great stereo speakers
  • Modest chipset, not well suited to gaming
  • No NFC
  • Slow charging - 29% in 30 mins
  • If you're not hell-bent on battery life, more value can be found elsewhere

Another marathon runner, the Moto G8 Power relies on the same chipset as the Realme 5 but it provides upgrades in several other areas like the slightly speedier charging, the more versatile quad-camera setup, and the 1080p screen.

Huawei P40 lite

Huawei P40 lite

Specs
  • 121h Endurance rating (33:21h calls, 18:04h web, 15:58h video), ideal for heavy talkers
  • Excellent performance, great for gaming
  • Very good photos out day and night
  • Large screen with small cutout
  • No Google Mobile Services
  • Memory expansion via NM cards
  • Uninspiring video recording, no EIS

The Huawei P40 Lite is one very balanced smartphone that excels in performance, battery life and camera quality. Its screen is ideal for gaming and streaming videos, too. There is only caveat - no Google services like most recent Huawei phones.

One really nice thing about the Huawei P40 Lite is its fast 40W charging. A full charge of its 4,200mAh battery takes 1 hour, but you get 70% in just 30 mins.

The P40 Lite performs admirably in the battery screen-on tests and will last you very long be it for web browsing, or watching videos.

The P40 Lite is also one of the best phones for gaming with the Kirin 810 chip coupled with the EMUI 10 gaming optimizations. Unfortunately, or not, you need to rely on sourcing your apps from places other than the Google Play Store.

Fastest charging

vivo iQOO 3 5G

vivo iQOO 3 5G

Specs
  • Among the fastest charging speeds we've seen - the 55W adapter takes it from 0 to full in 50 minutes
  • 118h Endurance rating (27:34h calls, 14:28h web, 25:37h video)
  • Great OLED screen, and also plenty bright
  • All-round camera setup, particularly good macros
  • Flagship Snapdragon 865 chipset
  • As with all proprietary solutions, the super-fast charging requires all the links in the chain - phone, cable and adapter
  • Unimpressive main camera output overall, generally mediocre low-light photos.
  • Limited regional availability

We just can't miss mentioning the vivo IQOO 3 5G - a flagship phone with super-fast charging. Topping up its 4,400mAh in less than 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.

The iQOO 3 is great for gaming thanks to its top of the line Snapdragon 865 chipset and the 180Hz touch-sensing does make a difference. The phone also offers special trigger buttons on its frame for enhanced gaming, there is a special 4D vibration motor, and the AK4377A independent audio chip with Hi-Res audio certification will be of value to the audiophiles for sure.

The camera has a lot of skills, though it won't impress with quality.

The more features and functionality, the more efficiency is needed to be sought.
