Apple Watch not fully charging
My wife’s Apple watch has recently begun to not charge fully, it will only charge ~70-75%. When placed on the charger, the charge ring illuminates, but at just past the 75% mark on the circle, there is a little hook that goes in towards the centre.
Does anyone have any good idea/reason that this has started to happen? Photo shows what it looks like when it is first put on charge
