I charged from 25% to 80% and it takes ≈1h (1½h max)

Then if you charge for :

90m from 25% to 80% with a total capacity of 5000 mAh :

you are charging at an avg speed of 2000(mA) (2 amps). (I did the math)

What I find weird is that your magic text seems to record in Amps instead of miliAmps as it should ...

Like imagine charging a 5000 mAh battery at just 1mA per hour..

Imagine that charging at 5000 mA it would take you 1h. (from 0 to 100)

At 2000 mA -> 2,1/2 hs (0 to 100)

At 10000 (like me) just 30m

In short there's no way the values are correct. Or it's for some reason displaying in Amps (divided by 1000)
