The OnePlus 9 also comes with 5G support. So if you have booked a suitable tariff and are in a 5G area, you can surf the mobile Internet at lightning speed. Wi-Fi 6 (WLAN-ax) is available in the home network. Bluetooth 5.2 and NFC are also on board, with the latter being used for mobile payments. Dual SIM is made possible via two individual nano SIM cards. Both can be logged into the 5G network at the same time.
USB-C is used in the OnePlus 9 for wired connections. This interface has become as standard in modern smartphones as the absence of a headphone output, which the OnePlus 9 also connects to. It is a pity, however, that the scope of delivery does not include a corresponding adapter or a suitable headset.
The internal memory of our 256 GB test model had around 221 GB of free space after it was set up. That is massive, but must also be enough, because there is no SD card slot for memory expansion.
We really like the workmanship of the OnePlus 9 – there is nothing to complain about here. With a weight of less than 200 grams, it is also not too heavy in the hand and is visually appealing thanks to the glossy look in “Winter Mist” (purple), “Arctic Sky” (blue) and “Astral Black” (black). It’s just a shame that, unlike the Pro model, OnePlus has waived IP certification and thus official protection against dust or water.
We really liked the integrated speakers in the test. These emit a good stereo sound that scores with a relatively good bass and does not begin to clink even at full volume. The OnePlus 9 also supports Dolby Atmos. You can unlock it either using the classic code or the fingerprint sensor or facial recognition.
