    How do you even get that new BIOS? It's not available on Dell's website...
    I've turned off automatic BIOS update option (I forgot the exact name of the option) in BIOS, so I don't get it in Windows update...

    Hey guys, I have a question - already some time ago I noticed my charging speed was limited to 40 watts. If the battery charge was below 35% it would charge faster, up to 80 watts, but when once it reaches 35% the charging goes down to 40 watts, even if the Express charge option is on in the Dell Power app.

    I just reinstalled Windows, thinking something was wrong with my Windows, but again the same thing.
    Do you have the same charging limit of 40 watts?
    Maybe it was introduced in some recent BIOS (I'm on 1.16), or there's something wrong with my laptop/battery?

    This is the italian Dell website.
    I think he would refer to 1.18.1, not 1.8.1

    Slow charging generally extends battery life (due to lower temperatures) so is a good thing for all your devices IMHO.

    Yeah, I know that, but sometimes I need the fast charging. I just know the laptop used to charge much faster, and would slow down when the battery charge reached around 75%.

    Do you still have your 9570? How fast does it charge when on standard charge?
    I just need to know if my laptop/battery is faulty or this charging behaviour has been introduced for ALL in some prior BIOS.

    I just tried to turn on the express charge option when the battery is below 35% and the charging speed even goes down all the way to 35W! That's slower than my phone charging. The standard charge option charges at 75W when the battery is below 35% and slows down to 40W after that.
