A:Answer I'm using this charger with my Samsung Galaxy S8, and -- as an example -- it takes about 1-2 hours to charge from 50% to 100%. (When I set the phone on the pad, my Galaxy S8 actually predicts an expected time to charge fully.) I'm guessing that the charge time depends on the specific phone you have... some phones may limit charge rate to prevent overcharging or overheating. Also, make sure you place the phone on the pad correctly and the blue LED lights up -- sometimes I've misplaced the phone on the pad, and the blue LED doesn't come on, indicating that the pad doesn't "see" the phone, and isn't charging. Good luck!
