I'm having terrible bother with my watch going into power reserve mode on my apple watch using watchOS 3 when i use clothing that covers the screen. Everything is perfect when i wear short sleeved tops but every time i go out for a walk wearing my heavy rain coat or a long sleeved jumper and want my workout to be recorded it will go into power reserve mode several times in an hour. YES i know this is Beta software on the device but I'm wanting to know if this is happening others or if i'm on my own with this issue? lately i'm having to walk with my coat left arm slight pulled up to stop this happening.
