The GT 5 comes with a built-in microphone and speaker, enabling users to take calls directly from the watch when connected to a phone. Call quality is decent enough to get the job done. Users can also store music files on the watch itself and then play that music via Bluetooth straight to their earbuds, allowing for some offline, phone-free workout time.
The GT 5 offers up to 14 days of battery life though heavy usage (with continuous heart rate monitoring and GPS) reduces that to around a week. The watch charges from 0 to 100% in about an hour, using Huawei’s proprietary charging dock.
It also has automatic sleep mode engagement, which I found to work reliably. The watch also supports Huawei’s new Sleep Breathing Awareness feature, which helps detect potential respiratory issues during sleep.
