does samsung wireless charging support 7.5w ?

[auzzuro]

The iOS 11.2 betas include support for faster 7.5 watt wireless charging; the current public releases of iOS 11 limit iPhone 8 and iPhone X to 5W Qi wireless charging only. just wondering samsung wireless charging support 7.5w with 11.2?

No, as I know Samsung wireless charger support 10W(output is 9V, 1.67A), only the phone support 10W fast charging. The request of iPhone fast charging mode is 7.5W, can not match it.

9v x 1.67a = 15 Watts?

I have an usb power meter and when charging at 80%, it’s pulling 6-7 Watts. I’ll try again when battery meter drops to below 20%.

Sry, is 5V 2A, not 9V, 1.67A

I have a Samsung mini wireless charger rated for 5V and 2A. I couldn’t tell any difference before and after the iOS 11.2 update.

More importantly, the blue LED on the charger remains blue with 100% charged iPhone. But the LED turns to green when my Samsung S8 is fully charged. I am just hoping the charger is not doing any harm to my iPhone...

My Samsung charger never turns green. My usb meter shows 0.7-0.8 Watts at 100% so the phone probably blocked charging or using wireless energy to power the phone.

Probably because a number of people have so far noted only the Mophie and Belkin fast wireless chargers sold by Apple are supported by iOS 11.2 to fast charge. All other third party "fast" wireless chargers are not currently supported.

I just bought a Samsung qi certified fast charge charging pad. Recognizes my iphone X right away. Pretty cool. Although I am not sure it is more volts than the apple charging cube.

Wouldn’t using USB power meters not be the best test of power output since some of it is lost due to transmission inefficiencies? I mean I understand if a cable was directly plugged into the phone, but it isn’t. All it should be measuring is the power draw of the wireless charger, not what the phone is actually taking in.

I ran the test at 40% of battery and the usb meter is showing 7.5 watts +/- 0.3 watts. Above 60% I get about 5-6 watts. So fast charging seems to be working with the samsung charger.
