Samsung tab S7+ charging problem

Hello 

I don't know how to better explain my problem to you 

(on top of that i don't speak english)

but if you watch the video you might understand

and maybe you will be able to help me

(I do not speak English) 

I have an application called ampere (an application that allows you to display the energy received or lost by the battery in real time)

I open the amp application it tells me for 

example 

2500 mA (Fast Charge)

4000 mA (Super Fast Charging) 

I open a second call of duty window 

and third window clash of clans 

I wait a bit and there when I look at the ampere application it tells me 300 mA or 200mA or 80mA or 60mA 

it will never go up to 2000mA or 4000mA again as long as the application remains open 

when I play Call of Duty it's 80mA (it will drain the battery even if I'm connected Fast Charge or Super Fast Charging)

you might understand better by watching the videos 

when I open windows or games on my laptop I don't know how to tell you that it does not charge, it charges very slowly, it discharges, even only one game call of duty 

even if I am connected Fast Charge or Super Fast Charging on my laptop tab s6 it wasn't doing that 

test on your tablet please (with the same apps if possible)

with a single application geekbench https://streamable.com/xbizzi

You've missed what I told you. Look at your battery %, around 90% your battery charge rate is being dropped. That's very normal behaviour as its done to reduce potential heat and keep your battery life healthy.

Can you tell me what charger you're using and provide a picture, thanks.

I have already tested with a super fast charger I still had the same problem you have not seen the video with 4000ma

OK that's the charger which comes with the tablet which is rated maximum charge of 15W. I'm using the official Samsung 45W charger hence the 7000mA charge rate. When you see the charge speed drop drastically, this is due to temperature rises in both chipset and battery. The chargers automatically adjust charging speed to keep your device safe. It's perfectly normal and doesn't denote a charging problem.

I opened 5 applications that it does not want to load

Can you tell me what charger is your super fast charger and a pic if possible, thanks.

Looking at your first video I can tell you your battery temperature looks a little high, so your device must be pretty warm. It also seems to fit perfectly with charge speeds increasing as the temperature goes down, so nothing wrong there I can see other than a warm device. The adjustments are more than purely temperature adjusted, but that has a large part to do with the charging speed.

Device load will also affect charging speed because of extra heat generated and power consumption and do not forget screen recording is also taking its toll on your devices heat/load. Bottom line is, all this testing isn't doing good for your devices battery, but seeing your charging speeds and amounts, nothing looks wrong there.
