Best phone battery life in 2020

These are the smartphones with the best phone battery life based on our tests

Pick a device with the best phone battery life, and you’ll never need to worry about having to find a place to recharge your handset ever again.

Battery life remains a major consideration when you’re buying a phones, even as the sizes of those power packs continue to grow.  Recent flagships from Samsung and LG feature massive 5,000 mAh batteries, offering the promise of phones that can go all day on a single charge. But which devices can really boast that they provide the best battery life on a single charge?

In our battery test, we have phones continuously surf the web over LTE or 5G until they run out of juice. The average phone lasts around 10 hours, but the phones we’ve highlighted here held out for at least 11 hours. The kind of endurance where you’re less reliant on one of our best portable charger picks.


  1. Moto G Power (16:10)

There’s a new handset with the best phone battery life, and it’s the Moto G Power, which takes the crown from the very phone it replaces. Like last year’s Moto G7 Power, this new version of Motorola’s budget phone features a 5,000 mAh battery. And the Moto G Power makes the most of it, lasting more than 16 hours on our battery test. That’s a half-hour better than the Moto G7 Power did.

Don’t expect fast charging from this phone. After 30 minutes of charging a depleted battery, the Moto G Power’s battery indicator only showed a reading of 21%. Then again, 5,000 mAh is a mighty big power pack to fill, and it’s not like you’re going to need to charge this phone frequently.

The Moto G Power retains one other attractive feature from the G7 Power — its $249 price. That’s a bargain when you get a phone that can last all day in return.

  1. Moto G7 Power (15:35)

After a year in the top spot as the device with the best phone battery life, the Moto G7 Power slips down to second place. Still, that’s a pretty lofty position, considering it’s one of three phones that we’ve tested in the past two years to feature more than 15 hours of battery life — and two of them come from Motorola.

Considering that the Moto G Power features newer specs and multiple cameras, it’s hard to get as excited about last year’s Moto G7 Power, unless you can find that older phone at a significant discount from its original $249 price. T-Mobilehas marked the phone down to $200 as of this writing, and you can get the G7 Power for less than $200 at Verizon-owned Visible.

  1. Asus ZenFone 6 (15:01)

The camera on last year’s Asus ZenFone 6 grabs all the attention — it swivels around so that the same lenses pull off double-duty as both the front and rear cameras — but to us, this phone’s endurance is the real story.

The ZenFone made our best phone battery life list by lasting more than 15 hours on our battery test — not a surprise given the beefy 5,000 mAh power pack inside the ZenFone 6. Throw in fast charging and an efficient Snapdragon 855 processor, and that’s a lot of power for a phone that starts at less than $500.

  1. Samsung Galaxy A20 (13:46)

It may not have the flash and features of Samsung’s more premium handsets, but if you’re looking for the best phone battery life at a cheap price, the Galaxy A20 delivers. The phone lasted more than 13.5 hours on our battery test, thanks to a massive 4,000 mAh battery.

Charge times are respectable, too, as the A20 delivers 15-watt charging that can get a drained battery up to 30% after half-an-hour of charging. You’ll make some sacrifices for the A20’s $239 price tag, but you’ll get lots of battery life in return.

  1. LG V60 ThinQ 5G (12:46)

It’s time to put LG’s reputation for producing phones with less-than-stellar battery life to rest. The LG V60 ThinQ 5G continues LG’s recent spate of long-lasting phones, even with this handset boasting power-hungry 5G compatibility.

LG went big with the battery, putting a 5,000 mAh power pack inside the V60. That helped the phone last nearly 13 hours on our battery test, making it the longest-lasting flagship phone since last year’s Huawei P30 Pro.

There’s a big drop-off in battery life if you keep the V60’s second screen attachment plugged into the phone, though that’s probably not something a lot of people are going to do. Even then, getting 7 hours, 34 minutes of battery life when you’re powering a pair of 6.8-inch screens is a pretty impressive feat. We only wish the LG V60 ThinQ 5G’s charging capabilities were as impressive, with LG’s phone reaching a 51% charge after 30 minutes.

  1. Samsung Galaxy S10 Plus (12:35)

The 4,100 mAh battery in the Samsung Galaxy S10 Plus no problem keeping that 6.4-inch Dynamic AMOLED display powered up throughout the day. We managed to get a little more than 12.5 hours out of this handset, which is the best phone battery life we’ve seen from a Samsung flagship device, even if this one is getting up there in age.

But a long-lasting battery is only part of the power management story with the S10 Plus. All of the S10 phones offer a Wireless PowerShare feature that lets you wireless charge other device — yes, even iPhones — by placing them on the back of the S10.

You can find more recent Samsung phones, but the S10 Plus remains available. Even better, the arrival of the Galaxy S20 lineup has cut the cost of the Galaxy S10 Plus to less than $900.

  1. Moto G Fast (12:17)

It’s no Moto G Power, but what is these days? Instead, the Moto G Fast rides its 4,000 mAh battery to a 12 hour and 17 minute result on our test — nearly four hours behind its Moto G sibling but still among the Top Ten for best phone battery life of the devices we’ve tested in the last 18 months. That’s terrific for a phone that’s available for less than $200

Don’t expect fast charge times from this budget phone. After 30 minutes, the stock charger that came with the Moto G Fast only got the drained phone up to 26%, according to its battery indicator.

  1. Moto G Stylus (12:13)

Speaking of Moto’s G lineup, the Moto G Stylus may trade in the bigger batteries on the Moto G Power and Moto G Fast in favor of a productivity-boosting stylus, but that doesn’t mean it isn’t capable of lasting a long time on a charge. Equipped with a 4,000 mAh battery, the Moto G Stylus lasted 12 hours and 13 minutes on our test — impressive, even if it’s not Moto G Power-level endurance.

While the G Stylus will go a long time between charges, don’t expect that 4,000 mAh battery to refill quickly. After 15 minutes of charging a completely drained phone, the Moto G Stylus’ battery indicator was back up to 15% and just shy of 30% after half-an-hour. Still, it’s nice to know that for $300, you can have a phone that will last you throughout the day and come with a pretty clever stylus for jotting down notes as part of the bargain.

Motorola’s less midrange 5G phone delivers better battery life than its more expensive counterpart. The Motorola Edge rode its 4,500 mAh battery to an average time of 12 hours and 12 minutes on our test, beating out the Motorola Edge Plus by an hour and 17 minutes. That, plus the $300 price difference between the two phones, makes the Motorola Edge a compelling option.

Note that we recorded that time when the phone’s display was set to a 60Hz refresh rate. Enabling a 90Hz refresh rate on the Motorola Edge reduced its battery life to 11 hours, 35 minutes, which still would have been good enough to land the phone on this best phone battery life list. (We also tested the phone on Verizon’s network, as it had the stronger signal where our reviewer was located. Results may vary on T-Mobile’s network, but not enough to remove the Motorola Edge from this list.)

We wish the Motorola Edge charged faster, as the drained phone only got back up to 36% after a half-hour of using the included 18W charger. Still, if you want a 5G phone with a fast refreshing screen that doesn’t run out of juice as quickly as similar devices, the Motorola Edge is a good option at $699.

  1. Samsung Galaxy S20 Ultra

As with many phones that feature a fast refresh rate for their displays, it was a tale of two battery test results when we put the Galaxy S20 Ultra and its 5,000 mAh battery to test. Running our test on Samsung’s flagship phone with the display set to the default 60Hz refresh rate, the phone turned in an average time of 11 hours, 58 minutes — a better result than Apple’s iPhones.

But one of the marquee features on the Galaxy S20 lineup is the screen’s faster 120Hz refresh rate, which allows for smoother scrolling. When we turned on that feature and re-ran our test, the S20 Ultra’s result dropped by 3 hours.

The Galaxy S20 Ultra charges up quickly, thanks to the 25-watt charger that comes with the phone. After 30 minutes of charging, we got the battery back up to 63%.
