Wireless Charging - Huawei Mate 20 Pro Questions & Answers

Hi guys.
Hope your all well,
I have bought a new Huawei Mate 20 Pro wanted one as soon as they can out. I have put mine in a book type case I find it easier to handle, I HAVE A QUESTION. Will the phone charge through the case OR would I have to keep taking the phone out of the case. Any help would be great appreciated, thank you all for your help and time.

Wireless charging works through almost all cases so you should be fine.

Using my "Anker" wireless charger (here) and my "huawei smart view flip cover" (here) it charges no problem with case on. even with the case open flipped around to the back of the phone it still charges fine.
I guess it depends on how thick the case is or how good the charger is

Thank you
Thank you tweedie for your reply, I see the charger is a 10w charger, you are the only person to come back with positive feed back, my case is similar idea as yours, if you look on eBay brown/tan for a Huawei mate 20 pro, I'm thinking a 10-15w charger would be better than a cheaper low wattage charger.
Thank you again

If you want 15W charging, I woudn't choose anything different than Huawei's original charger. Not 100% sure, but I think generic 15W Qi isn't supported, the phone seems to trigger a lower wattage. Huawei is quite vague on this, it just states "you can charge at 15W using our SuperCharge technology, but Qi is supported as well", but doesn't state wether you can expect full speed if you go the Qi way. I got 2 supposedly 15W generic chargers and they were MUCH slower than the Huawei's ones I got after (and the phone was getting hotter still).

Yeah I only got a 10w charger as the original Huawei's charger last time I looked was 3x the price and wanted a desktop version rather then something flat. Wasn't too bothered about the time difference in charging as battery life are pretty awesome anyway! Maybe when the price comes down, then I'll get one. I do see the "green bubbling up" fancy animation, and charges up pretty quick. The Anker wireless charger I think is a good brand to some other cheapo Chinese brands.
As for the case, if its leather, I am assuming its pretty thick, but with my non scientific measurements, my charger handled at least 40 pages of glossy book/magazine paper that it can handle wireless charging! Not sure if further away from charger would make it less wattage getting through to the phone!

does anyone know of an app to show me what wattage is coming through whilst charging? thanks

It's not amazingly accurate but you could use something like Ampere - it will give the current charging amps & voltage. Watts = amps x volts so you can get an approximation.

cheers. will try that out. its at 100% at the moment, so will give it a couple of hours to lose some charge!

Usually if I'm looking for something I Google it. Type exactly what your looking for, you can always add the best, guaranteed it usually throws something up.

well, not sure if I will be disappointed, but it came up at 820mA and I see 4.327V, so based on that calculation it came up as 3548. I doubt thats 35W, so I am gonna guess that is 3.5W? not sure where the advertised 10W charger comes in!
(based at currently already charged of 96% full)

I won't bother replying in future then. I gave you all the positive feedback you needed but I guess you wanted more answers to your question than you asked.
You answered your own question about the wattage so did not require a response.
Peace out

Yeah, 3.5W (although Ampere don't claim to be amazingly accurate)
There can be all sorts of issues with adapter compatibility. Did it come with an adapter? If not, does the adapter you're using support qc3.0?
I've got a supposed 15W charger so will test it when I get home.

well, I don't think I can recommend Anker wireless charger (here) - suppose to be 10W, but after using that Ampere program, it tells me that at most with the original Huawei adapter (though with a good quality usbB cable as Anker wireless isn't usbc), I got 910mA x 3.93v = 3.5w (with or without case - no difference). Quite poor compared to charging via the original adapter and usbC cable which gave me 3450mA x 4.0518v = 13.9w. I didn't expect wireless charging to match the same power as via wired, but did not expect that big a difference.

Pretty sure you are calculating it wrong. Ampere shows current charging amps in mA and the voltage of the battery - this will go up with the percentage of the battery.
I don't think there is any app that shows what is the voltage of the charge, just amperage.
Saying that, I can see that my both wireless chargers charge with similar current averaging 800mAh and max is around 1mAh. At the moment I have one connected to qc 3.0 18w adapter.
Connecting phone to the same adapter using usb c cable gives me...similar values, surprisingly.
iPad chargers (10W/12W) are very similar to qc3.0 charger, and Anker 6 port charger (allegedly 5v/2.4a max per port) is probably the "fastest" of the lot.
Connecting phone to stock 40W charger with any usb c cable (tried few 'generic' 2m cables) give me results in around 4000 mA.
I'm not an expert in the field so I don't understand if this means that both wireless chargers are charging at around 10w or the adapter (Anker single usb-a port) can't charge the phone with full speed.

ah right, that kinda makes sense. I thought that Volt mentioned in the app Ampere was the Volt coming in as its charging and not realise that its actually the Volt of the remaining battery. Obviously, my calculation is completely wrong. thanks for pointing that out!

Hi Fafner76.
Thank you so much for your advice regarding the Huawei Charger. I ordered a new one, got it for £20 which was a result as they at about £40. It arrived this morning, I placed my Huawei mate 20 pro with the case on it and hey presto it started charging straight away no prompting needed. So thank you again

Hi Fafner 76
I did the charge On the huawei wireless charger and it works perfect with the case on and it charges at roughly as quick, its a result
