Oppo has now released the Watch 4 Pro, a premium smartwatch with a 1.91-inch AMOLED display and a stainless steel case. The Oppo Watch 4 Pro also has a Snapdragon W5 Gen 1 chipset, 2 GB of RAM and a 570 mAh battery, among other features.
Additionally, the Watch 4 Pro has more pronounced edges than the Watch 3 Pro, arguably making the former look more modern than the latter as a result. Moreover, Oppo has increased the size of the smartwatch's physical buttons, which should make them easier to use. The Watch 4 Pro retains a Snapdragon W5 Gen 1 chipset too, which it augments with 2 GB of RAM and a co-processor that should achieve up to 14 days of battery life from its 570 mAh battery. Please note that Oppo reduces this battery life estimate to 5 days of normal use. Furthermore, the Watch 4 Pro has a skin temperature sensor, an integrated electrocardiogram (ECG), an 8-channel heart rate sensor and a 16-channel SpO2 sensor.
Supposedly, the smartwatch is also compatible with external blood glucose monitors. Elsewhere, Oppo has included an eSIM for LTE connectiviy, an NFC chip for making contactless payments and over 100 sports modes. For reference, the Watch 4 Pro is compatible with devices running at least Android 8.0 or iOS 13. Unfortunately, a global release date remains unknown at this stage .
