The Pixel 4 has stereo speakers, which we found to work well but which don’t offer anything groundbreaking in the world of smartphone audio. Google has looked to software rather than hardware to give its cameras the edge in recent years, and here it's added an improved ‘neural learning’ AI chip for improved software manipulation of images. This Pixel 4 also supports wireless charging, which we found useful when sitting at a desk, as we could prop the device up on a wireless charging stand or place it on a charging mat to ensure it was topped up throughout the day.

A saving grace here is that the Pixel 4 comes with some impressive fast-charging technology, which we found could charge the phone from 0-50% in 38 minutes if you use the USB-C charger included in the box.The software on the Google Pixel 4 also works smoothly. On-screen you'll find Android 10, the latest version of Google's mobile operating system, which features the firm's smart assistant baked into its core and new gesture controls. As mentioned, the big upgrade on the Pixel 4 is the inclusion of a second rear camera – this is the first time Google has put more than one lens on the rear of a handset. It's not an especially stylish implementation, but it has allowed Google to group two cameras (the first time it's included a second snapper on the rear of a phone), the flash and sensors into one area. Two rear cameras is still pretty modest these days though, with most high-end flagships boasting three, four and in some cases even five. Battery life is one of the weakest elements of the Pixel 4, and it’s quite a let-down to find such poor performance in this area on a modern flagship phone.

You can double-tap the Pokémon to cycle through different characters, with Pikachu and Eevee among those on board. It's a fun inclusion, especially if you're a Pokémon fan, but again it's fairly basic interaction. The Pixel 4 display is smaller than those on most Android flagship phones, but that doesn’t mean it isn’t a top-level piece of tech. Google likes to keep things simple in terms of hardware though, and there's a 12MP main camera (f/1.7, 77-degree field of view), assisted by the new 16MP telephoto lens (f/2.4, 52-degree field of view), allowing for improved zoom, better low-light shots and enhanced portrait photography. Certain markets can only access some models though – for example, in the UK the orange variant is only available in 64GB, while both 64GB and 128GB are available in the US.The highlight of the display tech is a higher refresh rate that’s higher than you’ll find on most other devices. In a similar vein to the OnePlus 7 Pro and OnePlus 7T, the Pixel 4 comes with 90Hz refresh rate, which results in a smoother experience when scrolling through social media or playing games. The phone can survive a short submersion in water thanks to its IP68 water resistance rating, which we tested by dunking it in a park fountain without issue.
