I've read it should take 45mins 0-100. I put mine on charge at 60% with factory charger with 20+watt charger (tried a few) and it says 47 mins to charge up from 60. What gives? Thanks.
I put my GW7 on the charger every morning when it's at about 45-55%. As a rule, it takes me about 45-50 minutes to charge it full. I notice that once it reaches the low 90s, it slows down charging...probably to protect the battery.
My routine is to put my Ultra on the charger disc while watching evening TV every evening. It is generally about 69-70% and takes roughly 45 min to reach 100%.
