The battery was on 95% when I placed it on the wireless charger. I made a cup of tea and the light went from blue to green to indicate that the battery is now fully charged.
I would recommend this product to all as it really is nice to be able to place your phone down when you need a charge without having to plug it in all the time.
I forget to plug in my phone to charge sometimes as I don't like turning on the light to plug it in correctly. This will make charging a lot easier as I can now just place it on the charging dock when I am ready to go to sleep.
