Huawei Watch GT Abandons Google's Wear OS To Achieve Stellar Battery Life

Announced alongside the Mate 20 Pro and Mate 20, the Watch GT features a 1.39-inch circular OLED display (454 x 454), a ceramic bezel and a 316L stainless steel casing. The smartwatch has a TruSeen 3.0 heart rate sensor which can measure active and resting heart rates.

Thanks to its use of an efficient Cortex-M4 design (which has cores dedicated for low- and high-performance tasks) and LiteOS, the Watch GT achieves incredible battery life. Huawei says that the wearable can operate for up to 30 days if you only receive notifications and don't bother to turn on GPS or heart rate tracking.

Interestingly, Huawei says that the Watch GT can last for up to two weeks if you enable heart rate tracking and exercise for just an hour and a half a week; that exercise figure seems a little low for the target audience for this device. Finally, the Watch GT can operate for 22 hours continuously with GPS, heart rate tracking, and exercise tracking enabled.

The Watch GT has an onboard accelerometer, gyroscope, magnetometer, and barometer, but it forgoes both Wi-Fi and NFC support. It does, however, support Bluetooth 4.2 and Bluetooth Low Energy. And Huawei says that the Watch GT is compatible with both Android and iOS smartphones

The Huawei Watch GT will be available in Sport and Classic designs priced at €199 and €249 respectively.
