A:AnswerYes, it does charge the S20 line. Currently, it is one of the fastest (highest wattage) wireless chargers that the S20 can is readily able to take advantage of. Most phones cannot charge at 15w wireless - they are throttled to a max of around 10-12w.
A:AnswerWireless will not be FASTER than using the proper wall charger. On Note10+, as demonstrated in a review on YouTube that is easy to find, charging time is equal between using this wireless charger and the proper wall charger.
A:AnswerI was told ar best buy not to leave a phone on the charger for 30 days...I suppose we really should not leave them on more than a nights sleep. should actually take the power off when not in use as they are really never powered off. Better for the charger but then again it you have to plug in the wirrless before yo charge the phone you might as well plug in the phone. Phones like the S9 need a charge pretty much everyday so unplugging & plugging every day is about as good as plugging in the phone...OOOH well...
Least the notion to leave a phone on charger for a month is gone but I needed the phone to stay home for 30 days operational & with no one to charge it I will have to think of another way to do it. Still I suppose even if the phone runs out of power then would calls go to voice mail? Would they not come in at all? Does the phone need power to get the call??? I have it set to transfer to a google number...oooh well...
