Question(s) about Fast Wireless Charging

[karelj]

Does the S9/S9+ give any visual indication that a 'fast wireless charger' is indeed charging the phone at a "fast" rate?

I won a Choetech Dual Fast Wireless Charger but it did not come with a power adapter. I'm using the Samsung charger that came with my S9+ but I really can't tell what rate it's charging at.

Yup, it shows FAST CHARGING in the charging indicator text at the bottom of the notification shade, including estimated remaining charging time..

So it seems that even the Samsung charger is not good enough to enable fast charging on the Choetech pad.

Is that pad compatible with the S9 line? Have you tried a different charger/USB cable (although the charger should be a Fast-Charging one)? Also, while the phone is on the pad, go to Settings,Advanced Features, Accessories. Does the 'Fast Wireless Charging' option show up there? If so, is it on?

Perhaps it just needs more than a 15W adapter.

Yes, it does support the S9 line.

Uhhh...I don't have an option for 'Accessories' under 'Settings>Advanced Features'

I think you are right. The power adapter that comes with it on Amazon is listed as a Qualcomm 18W Quick Charge Adapter.

Fast charging toggle can be also found in the battery settings...

Yes, but that only relates to a wired connection/charging as far as I know. Selecting this had no effect on the wireless charging rate for me.
I'm starting to think that Gayle Lynn's response nails it. I need to use a power adapter with at least 18W

Unless the phone is plopped to a fast charging wireless base once, you won't have the option in the settings. If it's kit there, the phone sn't recognizing it as a fast charging one.
