SuperCharge honor and huawei battery harmful?

I recently bought an Honor 10. This is my first honor. My question is about the SuperCharge. Is the SuperCharge seriously harmful for the battery or is it not so extremely harmful to the battery so you can confidently use it?

I'm not sure about that, but nowadays almost every cellphone has a quick / super charge and the cell phone manufacturers need to know what is harmful and what is not.

At least I do not think that will hurt. (As long as your phone does not get warm)

General supplement:

The Smartphone manufacturers limit the Volladung anyway to 85-90% and the smartphone is then reported as 100% to spare the battery.

And Fast Charge ends at 80%.

However, there's no protection against total discharge, although the smartphones are switched off at low charge levels (~ 5%), the smartphone is no longer used thereafter, can at self-discharge monthly rates of 2-5% after a month of battery no longer to use (because there are no intelligent external chargers for reactivation on the market until now)

To your question:

There have been a few cases where after a long time fast loading was no longer possible and Fast Charge became Normal Charge.

An explanation I have not found so far in the WWW.
