Wireless charging

[jocaboss]

Hi buds, how i can know if my s10 is charging fast through wireless. I have one Huawei CP60: https://consumer.huawei.com/en/accessories/wireless-charger/
And i bought from gearbest 15eur (without wall adapter) promo in February.
When i put my s10 charging i get wireless charging message. But I'm sure i can't get fast wireless charging.

Any help? This wireless charger don't support? The original wall adapter from s10 don't feed enough to get fast wireless charging?

When you put in on the charger, if it says "wirelessly charging" it's normal speed, if you see "rapidly" then it's fast charging. I don't think it's the wireless pad that makes a difference, it's the power block. I tried a 20$ cheap wireless charging pad with an old HTC power block and the phone says "wirelessly charging". If I use the samsung power block that came with the phone, it says something like "rapidly charging wirelessly".

Do you have Fast Wireless charge enabled? I have the plus but assume it is the same.

I can't find this option. When you get that?

Search for fast in the options. It's in the accessories section.

Settings - Advanced Options - Accessories. It is also listed in the Battery settings.

Thanks but seems my s10 don't have that option. It's Exynos Portuguese TPH s10... ?

Ah yes, am not familiar with Exynos version. Did you try as suggested to search fast charging in main Settings window? Maybe it is under a different category.

You can monitor the actual mAmps output supplied to your phone by your wired/wireless charger using CPUX app. (free). Personally, I don't use wireless charging, am not sold on it, but anyways, the app will help you figure out how fast is the charging going on at any given time during the process. I use the orig. charger and when I plug it @ 25-30% it shows the mA input just below 3000 then gradually reduced until fully charged. My desktop USB 3.O gets only up tu 900mA.
Here are two screenshots of cpux if you're not familiar with that appk.

Floats between 870 and 950mA. I don't know the charging voltage

Not very fast, there's some convenience in wireless charging, but I'm not a fan of it.

Thermal battery throttling as of 38°C?

My Galaxy S10 (EU/Exynos, stock) starts to reduce charging power from 11W to 6W above 38°C battery temperature. Test have been made with different original fast charging power supplys and wireless chargers. When i use a fan to cool no power throttling at all. It's summer now in Switzerland and i stated much higher charging time. Normal?

Strange. My s10 is exynos as well and the option is there. I use wireless charging occasionally for convenience but prefer cable charging (set to standard mode). If plug in Samsung charger it says Fully charged in 1hour 20 minutes. With other charger (Huawei) it says 2 hours 30 minute. So I think it depends on the plug and its output power. Also I charging my phone when it is around 10%.
Oh and one more thing: if using wireless charging phone gets hot.

Means that Samsung reduces charging power as of 38°C to prevent more heat and therefore reduced battery life... makes sense.
