5G phones with the best battery life

28 October 2020

We’ve reached a point where no self-respecting smartphone manufacturer dares release a flagship phone without 5G capability. Indeed, few will even launch a mid-range phone without at least the option of a 5G model.

This is good news for consumers, who can benefit from 5G’s increased download speeds and lower latency at a range of price points. But there’s one crucial specification that can get overlooked in all the 5G hype: battery life.

The price you pay for next-generation mobile network connectivity, at least at this point in history, is increased battery drain. This makes it imperative that anyone intending to make regular and intensive use of 5G choose a phone with better-than-average battery life.

With that in mind, we’ve put together a list of five 5G phones with the best battery life.

OnePlus 8T (5th of top 5)

OnePlus 8T

The 5G-ready OnePlus 8T packs a 4500 mAh battery - or rather two batteries that add up to 4500mAh (more on that in a bit) - and a Snapdragon 865 CPU that’s as efficient as it is powerful. Though it has a 120Hz display, it doesn’t feature the OnePlus 8 Pro’s power-sapping QHD+ resolution.

Still, it’s the little OnePlus-specific touches that earn the phone its place on this list. That includes some of the best-optimised software in the business.

Another advantage the OnePlus 8T has when it comes to battery performance is a stunningly fast 65w charging standard. Thanks to that novel dual-battery set-up, the One 8T can charge from 0 to 100% in around 40 minutes.

Samsung Galaxy S20 FE (4th of top 5))

Galaxy S20 FE

The Samsung Galaxy S20 FE has a vital edge over its big brothers. For one thing, it has a much bigger battery (4500 mAh) than the regular Samsung Galaxy S20.

Crucially, it also uses the Snapdragon 865 CPU in all 5G models. This is a far more energy-efficient (not to mention powerful) chip than the Exynos 990 that’s employed in the UK Galaxy S20, Galaxy S20 Ultra, and Galaxy Note 20.

Because of this, and Samsung’s extensive battery saving software, the Galaxy S20 FE’s 5G connectivity and super-fluid 120Hz display shouldn’t leave you looking for a wall socket before the end of the day.

Xiaomi Redmi K30 Pro Zoom (3rd of top 5)

Xiaomi Redmi K30 Pro Zoom

Xiaomi has equipped its excellent-value Redmi K30 Pro Zoom with a Snapdragon 865 CPU and a larger-than-average 4700 mAh battery.

Add in a nicely balanced FHD+ 6.67-inch Super AMOLED display, and you’re looking at a 5G phone that’s ready for the long haul.

Another stand-out feature is a pop-up selfie camera, so if you’re fed up of screen notches getting in the way of your 5G video streams, this is the phone to get.

Motorola Edge+ (2nd of top 5)

Motorola EDGE+

Like every other phone on this list, the Motorola Edge+ packs Qualcomm’s efficient Snapdragon 865 CPU, which ensures top performance and 5G speeds without rapidly draining your battery.

But like our top pick, Motorola has allied this with a massive 5000 mAh battery. Together with Motorola’s lean, unfussy UI, it’s a 5G phone with genuine legs.

Elsewhere, the Motorola Edge+ is a classy and well-specced device, with a 6.7-inch FHD+ curved OLED display and a fluid 90Hz refresh rate that doesn’t sap as much power as 120Hz phones.

1.LG V60 ThinQ 5G (1st of top 5)

LG V60 ThinQ 5G

LG has prioritised battery life with the LG V60 ThinQ 5G, and it shows. Like the Motorola Edge+, the key to its success lies in the combination of a Snapdragon 865 CPU and a large 5000 mAh battery.

Where the LG gains a slight edge over the Motorola is with its FHD+ P-OLED screen. While it’s slightly larger at 6.8-inches, it only reaches a 60Hz refresh rate, which makes it less fluid but also more energy efficient.

It’s worth noting that the LG V60 ThinQ also features a secondary screen peripheral that will add further power drain, but as this is essentially a fancy folio case it can be easily left off for those 5G-intensive occasions.

Conclusion

There isn’t a huge gap in performance between these five phones. All will last you well on your 5G roamings.

This means that while we’ve arranged these phones into a loose ranking, you can really take your pick according to other factors. Take a closer look at which design, price, and camera set-up appeals to you.

For example, the OnePlus 8T and the Motorola Edge+ have the cleanest software, the Xiaomi Redmi K30 Pro Zoom has a great camera, and the Samsung Galaxy S20 FE is simply an all-round strong performer.

But for raw battery performance under 5G load, you’ll struggle to do better than the LG V60 ThinQ 5G right now.
