5G phones with the best battery life

We’re now in the era of 5G phones, as while there’s still only a fairly small number of them, more are being released and announced all the time.

There are enough already that simply offering 5G isn’t enough – they need to additionally stand out through their specs and features, chief among which could be excellent battery life.

Good battery life is something that should be valued in all phones, but it’s especially important for 5G handsets, as downloading and streaming all the massive files 5G allows for can also push a phone’s battery. So with that in mind, ranked from worst to best, we’ve curated a list of the 5G phones with the best battery life.

5. OnePlus 7 Pro 5G

The OnePlus 7 Pro 5G has the same core specs as the OnePlus 7 Pro, which means a 4,000mAh battery. That’s a well above average but not enormous size.

However, in practice this phone comfortably lasts a day or more of moderate use, so you shouldn’t be in any danger of needing to charge it up before you get home from work or even a night out.

Having the same specs as the standard Pro also means it doesn’t support wireless charging, which is a shame, but it does support fast 30W wired charging, so you can juice it up very quickly.

Battery aside, this is an impressive all-round phone, with a great 6.67-inch 1440 x 3120 AMOLED screen with a 90Hz refresh rate for smooth interactions, a Snapdragon 855 chipset for plenty of power, and a capable triple-lens rear camera, along with a great design, an in-screen fingerprint scanner, a pop-up selfie camera, and most of the other bells and whistles you’d expect from a 5G flagship.

4. Samsung Galaxy S10 5G

The Samsung Galaxy S10 5G has one of the biggest batteries Samsung has ever put in a phone at 4,500mAh. Despite that, it doesn’t actually seem to perform quite as well as some Samsung phones with smaller batteries, but it still impresses.

With general mixed use you should get over a day out of it. There are several power-saving modes to help it out if needed, and it supports both 15W wired charging and wireless charging – so you can’t juice it up quite as fast as the OnePlus 7 Pro 5G, but you can do so without wires.

In other ways the Samsung Galaxy S10 5G is a thoroughly impressive phone, despite being older than some handsets on this list. It has a 6.7-inch 1440 x 3040 Dynamic AMOLED screen, water resistance, a high-end chipset, and a whopping six cameras, with four on the back and two on the front.

It also has a typically premium design and masses of storage, with up to 512GB built in. Even without 5G this would be the best phone in the S10 range, but with it it’s even better – and the battery doesn’t disappoint.

3. Oppo Reno 5G

The Oppo Reno 5G isn’t one of the biggest names in 5G phones, but that just means it’s cheaper than some rivals, and its 4,065mAh battery is both one of the bigger ones you’ll find and one of the best.

Its life is broadly similar to the S10 5G and OnePlus 7 Pro 5G, in that it can comfortably last a day or more of moderate use, but in general you should find it extend slightly further into a second day than those phones, or better endure a single day of heavy use.

It also supports fast 20W charging – splitting the difference between the S10 5G and the OnePlus 7 Pro 5G in terms of speed.

Moving beyond the battery, you get a truly all-screen front for the 6.6-inch 1080 x 2340 display, enabled through the pop-up shark fin-like selfie camera. The Oppo Reno 5G also has a high-end Snapdragon 855 chipset, 8GB of RAM, and a triple-lens rear camera, capable of an impressive 5x optical and 10x hybrid zoom.

2. Samsung Galaxy Fold

The Samsung Galaxy Fold isn’t a phone that you should necessarily buy unless you’re made of money and want the true cutting-edge of tech, but it does support 5G and it does have good battery life, lasting around a day and a half of moderate use.

That’s thanks to a 4,380mAh battery, one which also supports 15W fast charging and wireless charging.

Of course, the real highlight of the Galaxy Fold isn’t its battery or even its 5G, rather, it’s the fact that it folds. Yes, this is one of the very first foldable handsets. It has a 7.3-inch main screen that can be folded shut to keep the phone pocket-sized, and when shut you can make use of a 4.6-inch secondary display.

The Samsung Galaxy Fold also has three rear cameras, two cameras that are on the ‘front’ when viewing the main screen, and one above the secondary screen. Plus, the Galaxy Fold has masses of power, including an enormous 12GB of RAM.

1. Samsung Galaxy Note 10 Plus 5G

The Samsung Galaxy Note 10 Plus 5G is both the longest-lasting Samsung flagship and the longest-lasting 5G phone at the time of writing.

It has a 4,300mAh battery, so not the biggest in this list, but not far off, and in practice it can survive over a day and a half of use – with lighter use it can even make it through two days, which is about the most you can hope for from almost any smartphone.

The Note 10 Plus 5G also supports faster charging than most Samsung phones, at 45W, and allows for fast wireless charging too.

It’s a great handset in other ways as well, with one of the best screens you’ll find on a phone, namely a 6.8-inch 1440 x 3040 Dynamic AMOLED one, which also benefits from supporting the S Pen stylus that comes with the handset.

Plus, you get four rear cameras, 12GB of RAM and an Exynos 9825 chipset, which is even newer and better than the chipset in the Galaxy S10 range. While it’s the battery life that makes the Note 10 Plus 5G top this particular list, the phone as a whole is so good that it would come at or near the top of most lists.

Conclusion

There isn’t a huge amount of difference between the size and performance of the batteries in most of these phones – all of them will last at least a day, but only one will realistically last for two days.

As such, that one – the Galaxy Note 10 Plus 5G – is the clear winner, while any of the others are close enough in terms of battery performance that you’re best off considering other factors when choosing which to buy.

With that in mind, even though the Samsung Galaxy Fold is number two on our list, we wouldn’t actually recommend it to most people – it’s very expensive, and while its folding skills impress they’re yet to be perfected.

The Oppo Reno 5G, Samsung Galaxy S10 5G and OnePlus 7 Pro 5G are all fine phones though. And we should also mention the LG V50 ThinQ, which doesn’t quite make this list but came very, very close.
