There is no doubt that the Apple Watch is one of the best “smart” watches on the market for its health functions, the reliability of the heart rate sensor and its catalog of applications. However, it has one outstanding issue that Apple hasn’t yet been able to fix: battery life.

The day and a half or two that its battery usually lasts per charge is insufficient compared to alternatives such as Huawei’s and its up to 14 days of battery life, as in the case of the new Watch GT 3 (with HarmonyOS, app store and a fairly accurate heart rate sensor, similar to that of the Apple Watch).

Although Apple introduced faster charging in the Series 7 so it doesn’t have to spend so much time separated from our wrist, we hope the company further optimizes watchOS or introduces larger batteries so that it lasts a little longer without going through the charger. . In the meantime, we offer five power banks designed for Apple Watch with which we do not have to worry that it “dies”.
