Hi,

My Samsung S8 is charging at slow rate ( taking more time ) in " Fast Wireless Charging " mode then cable charging .

what is the possible reason ? is this a software bug or a hardware bug .

pls check the attachment showing charging time below.

wireless chrging is too slow as comoared to fast charging.
fast cable charge takes 1 hr 40 mins for 0% to 100% but fast wireless charging takes almost 3 hrs.

but both chargers give same output of .. both give 9V - 1.67 Amp output for charging ( usb charger and wireless charger )

But wireless charger isn't directly connected. Due to gap between charging pad and device, power is lost in the process.

[mukulsharma]

then smasung team didnt taken this into account while desiging wireless charging ? they should given power like 9V - 2amp or anything more to compensiate the loss ?

[AnkurBansal]

it can't be compensated. Samsung fast wireless charger is one of the fastest wireless charger in market. this technology is complex and still need time to grow.

Wireless fast charging is always slow than wired fast charging, that's how it is. Normal wireless charging will take 3hours. Normal wired charging will take 2hours. Wireless fast charge is same speed as wired normal charge.
