The OnePlus Watch 4 should achieve a battery life of up to 16 days despite Google Wear OS. To make this possible, OnePlus relies on a modern LTPO OLED panel and supports the Snapdragon W5 Gen 1 with an energy saving co-processor.

The brand new OnePlus Watch 4 is apparently based on the recently unveiled Oppo Watch X3, although OnePlus has adapted the design of the bezel and the watch bands. The OnePlus Watch 4 uses a titanium body that is water-resistant up to 50 meters, the display is protected from scratches by sapphire crystal.

OnePlus uses a Qualcomm Snapdragon W5 Gen 1 ARM processor, which is supported by a BES 2800 co-processor, 2 GB of RAM and 32 GB of flash memory. In conjunction with a 646 mAh battery, the smartwatch should achieve a battery life of up to 16 days in power-saving mode, while normal use should provide a battery life of five days. This is quite solid for a smartwatch with Google Wear OS. Wear OS allows access to third-party apps, Google's Gemini voice assistant and Google Wallet, which can be used to make contactless payments via NFC.
 


The smartwatch has an ECG, but this is currently only activated in China - it is not yet known whether the feature can ever be used in other regions. Nevertheless, the heart rate and SpO2 sensor as well as the skin temperature sensor also work in the rest of the world. A 60-second check-up collects data from all sensors at the same time. The OnePlus Watch 4 supports more than 100 sports modes.

Prices and availability

The OnePlus Watch 4 is already listed on the OnePlus website, but without any information on pricing. However, the smartwatch is already available on AliExpress for $342.
