OnePlus Watch4 46mm Evergreen

OnePlus Watch 4

It uses a dual-processor architecture to manage performance and power efficiency. The system combines the Qualcomm Snapdragon W5 Gen 1 platform, dedicated to high-demand tasks, with a BES2700 coprocessor optimised for background processes. This configuration allows switching between the Wear OS 5.0 operating system and a low-power RTOS environment. The device requires syncing with Android 9.0 or higher smartphones with Google Mobile Services (GMS); iOS and Android Go versions are not supported.

1.5-inch LTPO AMOLED Display

The 1.5-inch LTPO AMOLED display integrates dynamic refresh technology, which reduces power consumption in Always-On Display mode. The panel has a resolution of 466 x 466 pixels (326 dpi) and achieves a peak brightness of 3000 nits, making it easy to read in direct sunlight. The surface is protected by a scratch and impact resistant 2.5D sapphire glass.

Resistant

The 47-millimetre case is made of surgical-grade stainless steel with a matte PVD finish in black. It comes with a fluoroelastomer strap with steel buckle and 22 mm anchor system. In terms of durability, it is IP69 certified (high pressure water jet and temperature protection), 5ATM water resistant and MIL-STD-810H military standard.

Up to 100 hours of battery life

The 646 mAh battery offers up to 100 hours of battery life in smart mode under Wear OS. With heavy use (biometric sensors and active GPS), the battery life ranges from 48 to 60 hours, while the saver mode (RTOS) extends the runtime up to 15 days. VOOC 10W fast charging allows for 100% battery completion in 55 minutes.

Optical heart rate monitor

The sensor system includes an 8-channel optical heart rate monitor (HRV), blood oxygen measurement (SpO2), skin temperature sensor and electrocardiogram (ECG) hardware. These components enable the recording of advanced fatigue and recovery metrics.

GPS

For positioning, it integrates a dual-frequency Multi-GNSS L1+L5 system (Beidou, Galileo, GLONASS and QZSS), which improves accuracy in dense urban areas. Connectivity is completed with Bluetooth 5.3, dual-band Wi-Fi and NFC chip for payments via Google Wallet. This version does not include eSIM support; data transfer is via the paired smartphone.
