Phones with best battery life 2020 - buyer’s guide

GSMArena team, Last updated 05 January 2021.

Last updated: Jan 05, 2021 (Changelog)

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
  • Cheap, yet flagship-grade phone
  • Large uninterrupted OLED screen, HDR10+
  • Snapdragon 865 chip
  • Versatile camera setup
  • No microSD slot
  • Lacks water resistance

Our top pick for a battery life champ remains 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 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 spectacular.

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 is already an year-old phone yet it is still relevant with its battery capacity of 6,000mAh and 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.

There is a newer Galaxy M31s model, which has a slightly larger screen and higher-res camera sensors but remains the same where it matters the most - chipset, battery capacity, and software. You can opt for either model as they are quite similar - whichever you find cheaper.

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.

The Redmi Note 9S is available under different names on different markets. You can get also get it as Redmi Note 9 Pro in India, as well as the Poco M2 Pro, also in India.

Motorola Moto G9 Plus

Motorola Moto G9 Plus

Specs
  • 136h Endurance rating (52:57h calls, 16:20h web, 18:59h video)
  • Okay camera experience in daylight with versatile shooting modes
  • Large HDR10 screen
  • Stereo speakers
  • 30W fast charging
  • Decent mid-range chipset, NFC, 128GB storage
  • If you're not hell-bent on battery life, more value can be found elsewhere
  • The camera quality is subpar, bad ultrawide shots

Another marathon runner, the €250 Moto G9 Plus replaces our previous Moto G8 Power pick (about €180). It relies on a modern Snapdragon 730G and offers a large 6.81" 1080p HDR10 LCD screen. It offers speedier charging, NFC, and 128GB storage.

Its camera may feature four shooters, but only one is decent - the primary 64MP one. The ultrawide photos are disappointing, as well as the macro snaps. The G9 Plus isn't well-suited to handle photography on the go even of the specs sheet suggest otherwise.

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
  • Cheap!
  • No Google Mobile Services
  • Memory expansion via NM cards
  • Uninspiring video recording, no EIS

The €180 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.

Samsung Galaxy A21s

Samsung Galaxy A21s

Specs
  • 119h Endurance rating (39:38h calls, 18:02h web, 17:29h video)
  • Good quad-camera on the cheap
  • NFC, microSD, 3.5mm jack, FM radio
  • Cheap
  • Low-res screen
  • Poor processor performance
  • Sluggish charging

The €150 Samsung Galaxy A21s is one very affordable smartphone if battery life comes first. It has a large screen with a tiny cutout that's ideal for watching videos. The quad-camera on the back is decent, too.

The phone doesn't impress with performance; its screen is just 720p and with washed out colors. The Android 10 OS and One UI are still quite snappy, though.

So, the Galaxy S21s is for those of you with a limited budget and prioritize battery life above everything else. If that's not the case, then we should probably look elsewhere.

Xiaomi Mi Note 10 Lite

Xiaomi Mi Note 10 Lite

Specs
  • 117h Endurance rating (36:31h calls, 12:44h web, 21:19h video)
  • 30W charging
  • Large Full HD OLED HDR10 screen
  • Good quad-camera
  • Decent performance
  • NFC, 3.5mm jack, FM radio
  • No microSD
  • No tele camera, selfies could be better

The €300 Xiaomi Mi Note 10 Lite is one pretty attractive mid-range offer. It has a 6.47" 1080p OLED HDR10 screen and relies on the decent Snapdragon 730G chipset. The camera on the back offers good regular and ultrawide photos, videos turned out fine, too.

But the reason we included this Mi Note 10 Lite is because of its outstanding battery life and 30W fast charging. You can watch videos for 21 hours and then some or talk for 36 hours uninterrupted. The Mi Note 10 Lite offers great battery autonomy in addition to its balanced feature set and we do recommend it. Plus, it is very reasonably priced, too.

Realme 7 5G

Realme 7 5G

Specs
  • 129h Endurance rating (35:38h calls, 18:57h web, 16:03h video)
  • 30W charging
  • Large Full HD screen, 120Hz
  • Weather-sealed ports and loudspeaker
  • Good quad-camera
  • Very good performance, 5G
  • NFC, 3.5mm jack, microSD slot
  • 120Hz refresh rate handling and automatic switching needs work

The Realme 7 5G is among the cheapest 5G phones priced at around €300. It offers a large LCD screen with 120Hz refresh rate and runs on the Dimensity 800U 5G chip that provides decent performance. You can also rely on a pretty good quad-camera on the back.

The Realme 7 5G is a champ when it comes to battery life though. It scored a 129h endurance rating on our battery life test and is great for calls, web and even video playback. It charges quite fast, too. It is really hard to find flaws in this offer and that's why it deserves to go in ours and yours shopping lists.

Realme 7 Pro

Realme 7 Pro

Specs
  • 113h Endurance rating (35:48h calls, 16:12h web, 18:10h video)
  • 65W charging
  • Large OLED screen
  • Water-repellent coating
  • Good quad-camera
  • Very good performance
  • Stereo speakers, NFC, 3.5mm jack, microSD slot
  • 60Hz screen
  • No NFC (market dependent)
  • Underwhelming video recording quality

The Realme 7 Pro is about €30 more expensive over the Realme 7 5G and also impresses with battery life. While it doesn't come with an HRR screen, its panel is of the OLED kind and it features a stereo speakers setup.

The Realme 7 Pro did great in our battery life test with excellent on-screen tests and talk time. It can charge super-fast thanks to Realme's 65W SuperDart charging solution. It may not be featuring the smoothest of screens, but its performance and OLED panel are more than adequate, and we think it deserves a place here for its superb battery life and charging.

Xiaomi Poco M3

Xiaomi Poco M3

Specs
  • 154h Endurance rating (46:04h calls, 21:57h web, 17:03h video)
  • Large 1080p screen, small notch
  • Okay camera experience
  • 6,000mAh battery, 18W charging
  • Stereo speakers, IR port, microSD, 3.5mm jack
  • No ultrawide camera
  • No NFC
  • Gaming would require lowering the screen resolution

The $130/€150 Poco M3 is our next pick in our ever-expanding battery life champions list. It has a large high-res LCD screen, stereo speakers and a massive 6,000mAh battery with fast charging, which all make the M3 overqualified for this budget class. The phone scored an outstanding 154h endurance rating on our battery life test and it secured a spot on this list right then and there.

Gaming is very much possible, too, you just need to lower the graphics settings and resolution. The M3 won't be known for its camera prowess either, but it's not that bad. It makes up for that with speedy charging, a 3.5mm audio jack, stereo speakers, and a microSD storage.

Samsung Galaxy A42 5G

Samsung Galaxy A42 5G

Specs
  • 144h Endurance rating (41:01h calls, 19:12h web, 24:11h video)
  • Bright AMOLED, flagship-grade performance, 5G
  • Great photo and video quality
  • Recent software
  • Low-res screen
  • Sluggish charging

The €299 Samsung Galaxy A41 is one very interesting offer - it has an AMOLED screen and flagship-grade performance in addition to its great battery life and photography skill. It even offers 5G connectivity at that price.

There is a catch, though. The screen is of 720p resolution and charging the beefy battery takes longer than we'd have liked it. Than again, at that price we are getting plenty, more than we would have hoped for, in fact.

Samsung Galaxy M51

Samsung Galaxy M51

Specs
  • 156h Endurance rating (52:57h calls, 16:52h web, 25:14h video)
  • Large 1080p AMOLED, good performance
  • Great photo and video quality
  • Recent software
  • Not the best chip around
  • Others offer HRR screens at that price

The Samsung Galaxy M51 and its large 7,000mAh battery are an instant attention-grabber. Unlike the Galaxy A42 5G we recommended above, this M51 comes with a 1080p screen and is noticeably faster to charge. So, if the battery and the OLED resolution are of great importance - this could be the better option.

Once again there is a catch. The M51 is has an inferior chipset as far as gaming performance is concerned and it omits 5G. The Snapdragon 730G still provides enough punch for good gaming and Android/OneUI experience though. The only thing stopping us to instantly recommend this one is that others have HRR screens and stereo speakers for the same cash.

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 dated Snapdragon 665 chipset, which isn't great for gaming. It has a 1080p screen and a good quad-camera setup on the back, as well as great stereo speakers, so there is a lot to like in this G8 Power.

Finally, the Moto G8 Power is quite cheap now, even bargain at some carriers if you are up for a contract renewal. It's good to keep an eye on that one.

You can also find this phone as Moto G Power in the US - it's the same phone sans the telephoto and is slower to charge (10W vs. 18W).

I guess. Their phones aren't well-rounded. The chips are under-powered, the phone is too heavy, and the camera is bad overall. I think more people would buy it if the phone was well-rounded

I don't get those tests really. I've never had any phone since the original Nokia 3310 that lasts a day. I charge my phones, new phone every year, regardless of brands, 2-3 times a day. And turning off almost everything seems quite stupid w...
