Which phones have the best battery life? (2017)

We list the mobile phones with the longest battery life that you can buy in 2017, to keep you going well over 24 hours between charges.

Nobody likes seeing that power indicator dip into the red, and for phone addicts like us the longer we can stave off battery anxiety, the better. With that in mind, we’ve pieced together a list of phones offering the best battery life of the bunch right now.

Here's our list of the mobile phones with the best battery life from 2016/2017 that you can buy right now.

Samsung Galaxy S7 Edge

Arguably still one of the best phones on the market also happens to packs some of the smartest battery technology you can find right now. The impressively large 3600mAh cell inside the Galaxy S7 Edge ensures that you've got enough juice in the tank to last through almost a day and a half of heavy use.

Where it really stands out though is through the combination of fast charging, wireless charging and fast wireless charging on offer, meaning you have multiple ways to fill the S7 Edge back up in a jiffy.

Google Pixel XL

The HTC-made Google Pixel XL was preceded by a huge hype train, that pushed the phone's smart new Google Assistant, a supposedly best-in-class camera and, amongst other highlights, killer battery life. We like many were sceptical of Google's claims, but once we got our hands on the phone, it proved its worth in terms of both performance and longevity.

The massive 3450mAh battery paired to Android 7.1, which includes Doze on-the-go for greater power efficiency, can handle up to two days of use on a single charge and seven hours of life from just 15 charge time using Type-C USB PD (power delivery).

Although the LG G6 doesn’t offer the best battery life in this round-up, we’re still impressed that this mighty media machine gives over a day of full-on use per charge. That 5.7-inch screen boasts some of the latest display tech including Dolby Vision HDR support, for eye-punching visuals. Yet we still comfortably made it to the end of the day every time, even with a good bit of video streaming involved.

If you’re off on your travels and you need a device to keep you entertained, the G6 certainly delivers. Few premium mobiles offer the same excellent battery life.

Huawei Mate 9

Huawei has been moving from strength to strength in the smartphone space over the last couple of years and the Huawei Mate 9 served as the perfect alternative to the ill-fated Samsung Galaxy Note 7. It boasts a dual 20/12-megapixel Leica camera module, a top-notch Kirin 960 processor and a gargantuan 4000mAh battery.

All that power means it's not hard to expect up to an impressive three days of use per charge and the company's own fast charging tech means you jump from zero back to 100 per cent in around 90 minutes flat.

OnePlus 3T

The OnePlus 3 was already an impressive device thanks to its mix of premium design, powerful hardware and impressive affordability. It even offered respectable battery life and the best fast-charging technology on the market in Dash Charge, but then came the OnePlus 3T.

The 3T may look almost identical to its 2016 sibling, but this revised flagship brings with it an even larger 3400mAh battery (versus 3000mAh) into the mix and the same Dash Charge prowess, meaning a comfortable day and a half's worth of use and the ability to get another work day's charge (approximately seven hours) from just 30 minutes at the wall plug.

Moto Z Play

So far we've only touched on top-price flagships, but although the Moto Z is a brilliant high-end smartphone, its mid-range sibling, the Z Play is the one that proves to be the real powerhouse.

By being a snip thicker than the standard Moto Z, it brings back the standard 3.5mm headphone jack, but that waistline also conceals a sizeable 3510mAh battery which offers up two days of use without breaking a sweat. Qualcomm's Quick Charge 3.0 is available too, but if that wasn't enough support for the company's Moto Mods accessories means you can snap on the additional 2220mAh battery pack mod made by Incipio and last another and extra day or two, making this a great festival phone.

Moto G5 Plus

If you’re after a budget blower that offers long battery life, the Moto G5 Plus should be one of your first points of focus.

This handset boasts some great features, including a very capable 12-megapixel camera with Dual Pixel Autofocus - the kind of smart tech found on Samsung’s flagship phones. Despite this, the G5 Plus only costs £250, making it much more affordable than premium devices.

That fantastic all-round user experience thankfully stretches to the battery life too. The 3000mAh cell gives enough power to keep going for around two days, with plenty of use. That includes regular messaging, some media streaming, occasional calls and a fair bit of web browsing.

When it comes to powering up again, the G5 Plus is pretty nippy too. The Turbo Charge feature means just half an hour at the plug is enough for a full day of operation.

Sony Xperia XA1

For around the same price point as the Moto G5 Plus, you can also grab the Sony Xperia XA1. This impressive budget mobile lasts well into a second day on a single charge, or even a full 48 hours if you don’t hammer it non-stop. That result is bettered by next to no rivals; besides perhaps the next phone on our best battery life round-up.

The Xperia XA1 also supports quick charging, so you can quickly power it back up. Sony’s phone packs in the Qnovo Adaptive Charging tech too. This ensures that the battery doesn’t overcharge, which could damage the cell and impact longevity over time.

Lenovo P2

If even the Xperia XA1 and the Moto G5 Plus are a shade out of your budget, check out the Lenovo P2 - the only phone here packing an asking price under £200. This handset might not have the slickest looks or best camera, but it offers comparable performance to the more sophisticated Moto Z Play and features the biggest integrated battery of the whole list.

There's an unprecedented 5100mAh cell lurking under this phone's metal skin and it ensures that you can consistently reach up to three days of use between charges. Fast charging takes a little longer as you might expect, but you can still juice up this affordable handset in under two hours.
