Question about Huawei Watch GT Sport Edition

You get a charging cable that you can connect to a charging pad. There, however, the ur is charged via two contacts. Unfortunately, charging via an induction charging station is not possible. You can't charge it on the new Huawei Mate 20 Pro either.
But I have to say that I have had the watch on my wrist for 5 days now and still have the initial charge from unpacking it. I have only switched off the heart rate monitor. The rest is active.
