Huawei has presented the TalkBand B7, a successor to the 3-year-old TalkBand B6. The TalkBand B7 features a 1.53-inch AMOLED display, a built-in earpiece and a battery life that should last up to two days between charges.https://www.notebookcheck.net/Huawei-TalkBand-B7-debuts-as-new-all-in-on-smartwatch-and-earbud-combo.702797.0.html
Huawei has always been ahead of it's competition when it comes to looks and performance but they lack service and repair. None of the Huawei wearables watches has got battery replacement as an option and as I discovered after the warranty you have to send a $400 watch to the dustbin because of a unreplaceable battery. Huawei should spend effort and money in after sale service and repairs or drop their prices and advertise as disposable brand.
