Huawei GT4 does not support vertical wireless charging. The watch can only be charged wirelessly by placing it horizontally on a wireless charger. The vertical wireless charger requires the watch to be in a vertical position to charge, and the GT4 design does not support this charging method. Therefore, if you want to use the wireless charging function, you need to buy a horizontal wireless charger to charge, rather than a vertical wireless charger. I hope this answer can help you solve this problem.
