Huawei emphasizes multi-band satellite positioning, a 3000-nit peak display and long battery life. Health tracking is not a substitute for medical diagnosis. Huawei WATCH GT 7 UK specifications
In Notebookcheck's test, the 46 mm sample lasted around two weeks with health tracking on and AOD off. Message replies and app installation were more limited on iOS than Android.
Notebookcheck: Huawei Watch GT 7 reviewIn Notebookcheck’s test by Daniel Schmidt, the 46 mm version lasted two weeks with all health features on and the always-on display off. Dual-band GNSS came close to a Garmin Venu 2 on a bike ride, with the Garmin slightly better only on tight turns, and heart rate stayed within one beat of a Polar H10 chest strap. With an iPhone, notification settings are more limited, you cannot reply to messages from the watch and, without AppGallery, on-watch navigation is not possible; Huawei Health not being on the Play Store is flagged because of fake-app risk.
