The iOS 11.2 update will allow for 7.5 charging. I have the Samsung convertible fast wireless charger and my question is will it be capable of 7.5w wireless charging?
 
Yes, 7.5w is considered normal charging on QI chargers, the Samsung fast wireless chargers are 15w.

So will it charge the iPhone X at 7.5w?

I'm not sure.

Maybe 9W is the maximum charge wattage it supports, therefore it'd be able to charge at any value below that.

But, maybe Qi wireless charging standards require some kind of predefined charging profiles, like 5W, 7.5W, 9W and 15W. If that's the case, Samsung Convertible Wireless Charger only supports 5W and 9W (not 7.5W).

Anyway, I don't really know how Qi standards work. Maybe there's no need for predefined profiles (I hope so).

I expect youtubers to test that for us. :D

I have one that should arrive tomorrow. Can I test how fast it charges?

As long as you have iOS 11.2 beta 3+, yes.

Draw your phone battery to around 30% and check how much it charges over the course of 30 minutes.
 
I have this charger and iOS 11.2 beta installed so I’ll try this out later this evening when my battery is drained a bit.

Yes. The Samsung charger seems to support the 7.5W. Unfortunately the speed increase isn’t that noticable, especially compared with the 29W USB C charger or even the 10W iPad charger.
 
The Samsung convertible wireless charger doesn't seem to support 7.5W after the 11.2 update. I'm still getting 6W charge rate stated on coconut battery details like previous iOS versions. I really hope this is a bug or Apple provides a compatibility list of supported 7.5W wireless chargers.
 
Took about 4 hours to charge on 11.2. No difference with previous iOS versions
 
I read online that it should support it. I’m currently testing it right now and I’ll report back shortly.
 
So I started with 29% and put it on the charger for 30 minutes with normal settings (Bluetooth/Wi-Fi) on. The ending charge is 46%. I didn’t use the wireless charger prior to the update, so can anyone say if these results indicate 7.5W or not?
 
Macrumors article states:
For a separate post on wireless charging options, we've been investigating third-party wireless chargers, and it's looking like there may be a restriction put in place by Apple to limit 7.5W charging to approved manufacturers. As an example, on the Amazon page for this charger from Choetech, which says it is 7.5W, there is this message:

We get notice from Apple engineer that current IOS only support 5w qi wireless charging currently, 7.5w wireless charging is encrypted and never released to 3rd party manufacturer.

I dunno, but that is consistent with my Seneo charger I have for my X. I was getting that charge rate with 11.1.2
