[Huawei Mate 20 Pro Questions & Answers] Fafner76:
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).
[Huawei Mate 20 Pro Questions & Answers] tweedie:
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
[Huawei Mate 20 Pro Questions & Answers] Grondah:
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.
[Huawei Mate 20 Pro Questions & Answers] tweedie:
cheers. will try that out. its at 100% at the moment, so will give it a couple of hours to lose some charge!
[Huawei Mate 20 Pro Questions & Answers] JLB333:
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.
[Huawei Mate 20 Pro Questions & Answers] tweedie:
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)
[Huawei Mate 20 Pro Questions & Answers] Jonathan-H:
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
[Huawei Mate 20 Pro Questions & Answers] Grondah:
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.
[Huawei Mate 20 Pro Questions & Answers] tweedie:
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.
[Huawei Mate 20 Pro Questions & Answers] duRin90:
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.
[Huawei Mate 20 Pro Questions & Answers] tweedie:
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 everyone, as only a few versions of unbrick tool are available here and that they allow to rollback to specific versions of Oxygen OS I decided to search for more and succeeded in that.

As the instructions and Qualcomm drivers are already available here, I don't feel a need to rewrite them.

You can ask questions here on how to use and issues, however I might not be able to answer immediately.

Here are the files uploaded on AndroidFileHost ordered by Android version:

ANDROID 9:

OOS 9.0.6

OOS 9.0.5

OOS 9.0.4

ANDROID 8:

OOS 5.0.8

OOS 5.0.6

OOS 5.0.5

[OnePlus 3T Guides, News, & Discussion] Some_Random_Username:
Unfortunately no as I do not know any other provider hosting for free such an amount of files (I have same thread for OP3/5/5T/6/6T/7/7 Pro).

You could however select the mirror the more near to your location when downloading via AFH to get a faster download speed.
[OnePlus 3T Guides, News, & Discussion] mugenishere:
I tried it again from another server and this time it downloaded at 9MBPS! I got the file!

Thanks a load for sharing all these files! The normal "unbrick your phone" by flashing Android 6 wasn't working for me. From your link I was able to download the file for Android 8 (Oxygen 5.0.3). And it worked! My phone got unbricked finally!

A note to everyone: For whomever the earlier unbrick step doesn't work, you need to try downloading some other Oxygen OS (different Android version than the one you tried earlier).

I'm going to make a post in the main "unbrick" thread and let other people know about this. Once again, thanks a lot for posting these files and saving my phone!

I'm looking for devices (Android tablets) which supports OTG (to connect slave-devices, e.g., a mouse) and charging at the same time

There was a thread about Nexus 7 https://xdaforums.com/tab-s2/help/usb-otg-charge-t3588019

It needed a custom kernel to get OTG+Charging working

But it's very old, you can't buy a new Nexus 7 anymore

Also someone mentioned about Samsung tablets:

But these devices are also quite also and Samsung devices aren't that cheap anyway (if buying a new model)

So... Are there any devices (on sale) with normal prices which support OTG and Charging at the same time?

It doesn't matter if there is one port (input) or two (one for OTG and one for charging). Some Windows based tablets has a separate port for charging
[General Questions and Answers] User848:
Does Samsung Galaxy Tab A 7.0 (quite cheap) support OTG+Charging at the same time?
[General Questions and Answers] Droidriven:
What you need is a "powered USB hub", it has its own power supply and it will allow you to connect multiple USB devices(mouse, keyboard, flash drive, etc..) and charge the device at the same time by connecting your phone charger to the hub at the same time.

I use a USB to microUSB adapter, then connect the adapter to a USB hub that has 4 ports, then I use the adapter to connect the hub to the charging port on the device, then I connect a keyboard, mouse and phone charger to the USB hub.
[General Questions and Answers] User848:
It's not that easy with Android, believe me
[General Questions and Answers] Droidriven:
With a "powered" USB hub, it is, but not with a standard USB hub.
[General Questions and Answers] User848:
There is no such hub... At least officially. You won't find much. I saw one hub, but users said it was working only with Windows tablet (OTG+Charging), for Android OTG was working only

just google "Android OTG+Charging" you you'll it's quite a problem
[General Questions and Answers] Droidriven:
Something like this won't do the job?

https://www.amazon.com/TUSITA-Adaptor-Charging-Adapter-Raspberry/dp/B00LTHBCNM

Or this:

https://www.amazon.com/dp/B00VK9C24M/ref=cm_sw_su_dp

Of course, the device must support OTG and the accessory charging feature. If it doesn't, I'm not sure there is anything you can do to force it.
[General Questions and Answers] User848:
You have to test first

Does this hub supply a tablet with power or connected devices (slaves) to tablet? I need to charge a tablet and not connected devices (connected devices can get power from tablet)
[General Questions and Answers] Droidriven:
https://m.youtube.com/watch?v=YDtc37u9Kvo

I also edited my post above to add more info.
[General Questions and Answers] User848:
Well... manufactures don't give any information if their devices support all of this and what customers have to do to get it working (buy a specific hub or something else)

It's been two days and I only got reply from you. So we can say that it's not that easy and we can't be sure what to buy. I don't want to waste money if it's not going to work

Would be great if someone could really tell me which devices (tablets) support this feature, which hub should I get for such devices and so on

Thanks for the summary. I am also looking for android tablets that support USB host and charging at the same. A few old tablets from LG and ZTE have both micro-USB as charging port and a full-sized USB port to host other devices. But they are quite old. So ACA cable might be the way to go.

Question: Do we need to patch android os as described here use ACA cable?
[General Questions and Answers] Renate:
"You can lead a horse to water, but you can't make it drink."

You can always offer power to a hosting device.

Whether it takes it is another question.

If it's rooted you may find that you can control something to make it take it.

I've used back-powering hubs to power Androids.

This is a hub that has been modified to present power on the upstream port.

You can modify any powered hub to do this.

Has anyone come up with any solutions to this problem? I see this thread is a year old but I am here with a samsung tab A 8.0 2019, I have the exact same problem. I need to an external usb in service while charging, not one or the other.
[General Questions and Answers] Renate:
The use of a specific value resistor on the USB OTG ID pin to ground is pretty manufacturer specific.

Some devices have up to a 5 bit non-linear converter on the ID pin to give up to 32 modes.

I've found Samsung to be a fan of using the OTG ID pin.

I would definitely try values from short to 1 k to 1 M (in an exponential progression).

I don't even remember which device this is, but it gives you some idea of the values they might use:

0
2000
2604
3208
4014
4820
6030
8030
10030
12030
14460
17260
20500
24070
28700
34000
40200
49900
64900
80700
102000
121000
150000
200000
255000
301000
365000
442000
523000
619000
1000000
Open

If you're rooted you may be able to control the charge controller directly.

Some of this could be a pain if you were plugging/unplugging all the time.

If this is some hard-wired, fixed usage you could definitely hard wire your own 4 V charger into the battery.

You might try getting a few pots 10k, 50k, 250k and some 220k resistors to try your luck.
[General Questions and Answers] scampo77:
Whoever is reading this I can assure you that the Samsung tab A does not charge while OTG. Jamming a resistor in there to short out the sense pin is not a thing. These are pwm charging and have been for a while. Even after spending $100 on the OTG cable alone it's still not working.. rooting.. twrp.. none of It makes any difference at all
[General Questions and Answers] Renate:
How do you even do that? An OTG adapter is < $5. A connector is < $1.

OTG adapters normally have the ID grounded right inside the connector so you can't use that unless you chop up the connector.

You need to make up your own micro USB connector.

https://xdaforums.com/t/the-samsung-anyway-jig.1629359/#post-25532839

I don't have a Samsung Tab A so there's only so much that I can say.

All devices have a linear or DC buck converter that feeds USB power to the battery.

All devices (that do powered OTG) have a charge pump or a DC boost converter that feeds power to the USB jack.

Both of these are under control of the processor.

Look in your kernel source under usb/otg

You should easily be able to see if you have an ADC on your OTG ID pin or if it's just a GPIO.

Look at your device under /sys and see if there is anything suspicious with "adc" in its name.

find /sys -name '*adc*' 2>/dev/null

In worst case you'd have to modify a driver.
