OnePlus 9 Review

OnePlus is making its way back into the mainstream smartphone market. The brand is fairly popular with its good pricing and decent hardware. Even if you are not a fan of OnePlus, you should start checking it out. The new OnePlus 9 is a new flagship from the brand and starting $729, you can get top-notch features for 2021’s standards.

Design and display

Unlike the OnePlus 8 series with its curved display, the OnePlus 9 returns to a fully flat display. The 6.5-inch OLED panel offers 2400 x 1080 resolution, 20:9 aspect ratio, 120Hz refresh rate and vivid colours. Based on ambient light, the phone can adjust its colour temperature accordingly. The first impression is that the OnePlus 9 stands out with its amazing display quality. Although the design feels somewhat chunky, you can still hold it comfortably, with the ergonomic curved back and balanced weight distribution. Haptics are fantastic with very pleasing feedback when you press button. There are also stereo speakers that can the job done. They are loud, when playing music, although they can lack depth and sound quite harsh.


There are a couple of primary cameras on the back. The first one is the main 48MP snapper and the ultra-wide camera isn’t inferior with its 50MP resolution. Unfortunately, there’s no dedicated telephoto lens, with its two powerful cameras, the quality of digital zoom is quite decent, if you not overdo it. Details are quite pleasing, colours feel natural and there’s no software over-sharpening that ruins the look. When you are using the wide-angle mode, you can enable the 2x digital magnification. Unfortunately, both rear cameras seem to struggle in low-light situations and photos may look blurry at times. Video recording looks reasonably sharp, but it’s still affected by the camera’s drawbacks, like a cold cast and low dynamic range.

Hardware and software

So on to the exciting stuff, the OnePlus 9 comes with the powerful Qualcomm Snapdragon 888 chipset. There are two variants 8GB RAM / 128GB internal storage and 12GB RAM / 256GB internal storage. There’s no microSD slot, but these storage options should be adequate for any user. The OnePlus 9 still uses stock Android and the company only adds minor tweaks and reskinning. The Oxygen OS works smoothly and it’s quite joy to use. The device uses Android 11, OnePlus promises 3 years of security updates and 2 major Android updates. The combination of powerful hardware and lightweight interface allows great performance when taking photos, playing demanding 3D games and navigating the interface. Overall, users should be happy with the quick response.

Battery life

In terms of battery capacity, there’s nothing exceptional. Inside, there’s 4,500mAh battery, but you should be able to use the OnePlus 9 for one whole day. Fortunately, the Warp Charge 65T quick charging feature could top up the battery in just 30 minutes, if you urgently need to recharge the battery. It means, you could quickly charge the phone while taking a nap, working at office or having lunch.
