Which? tries out OnePlus 5 smartphone

We’ve got our hands on the OnePlus 5 mobile phone, to give you our expert first impressions ahead of our full test results. The OnePlus 5 is the latest of the Chinese company’s popular line of smartphones. While OnePlus may not be as well-known as Apple and Samsung, it’s making its mark with high-end smartphones that can compete on paper, yet undercut on price.

This new smartphone has a few features that firmly place it in the higher end of the market, such as a dual rear camera, fast-charging technology and up to 128GB of storage. But does this actually add up to a great quality smartphone, or is it just marketing mumbo jumbo? Head to our OnePlus 5 first look review[1] for our initial impressions, or keep reading for an overview of some of its mouth-watering specs.

There’s little doubt about it: mobile phones are getting bigger and bigger. The OnePlus 5 is no exception.

It has a palm-stretching 5.5-inch display – about the same size as the Apple iPhone 7 Plus[3] and Google Pixel XL[4]. One of the most talked-about features of the Samsung Galaxy S8[5] is its very narrow bezels at the top and bottom of the display. If you’re not a fan of this design, you’ll be glad to hear that the OnePlus 5 doesn’t follow the trend.

It has a non-tactile home button. That is, you touch it rather than press it – and you miss out on a satisfying click. This might be initially disconcerting if you’re used to a clickable home button, but we think it’s something you’ll get used to.

This button also works as the OnePlus 5’s fingerprint scanner.


Dual rear cameras are becoming more and more popular with smartphones. The OnePlus 5 joins the party, boasting a 16Mp sensor and 20Mp telephoto lens, along with a 16Mp selfie camera on the back. The theory is that you’ll be able to zoom more quickly and easily, and without seeing a drop in quality.

Head to our OnePlus 5 first look review[6] to find out whether our expert thought this phone takes convincing shots in normal- and low-light conditions. And when the full results of the OnePlus 5 come in, we’ll see just how well its camera stacks up against the competition.


The OnePlus 5 has a 3,300mAh battery, compared to the OnePlus 3T’s 3,400mAh offering.

However, battery life isn’t determined purely by battery size – it depends on other factors too, such as processor efficiency. The new phone also comes with fast-charging technology, promising 60% charge in just thirty minutes. We’re looking forward to putting the OnePlus 5 through its paces in our battery life tests, to find out whether it delivers on it claims.
