    I bought XPS 9570 which has Thunderbolt 3 port with power delivery function.
    I also have LG 27UD88W monitor which can source power to TB3 devices.
    So now with one cable I can replace:
    - USB cable between notebook and monitor USB hub
    - DP/HDMI cable
    - power adapter of my laptop.

    The problem I am facing is that I work 10-11 hrs. My notebook is connected to AC at that time.
    Can it harm my battery life?
    Is there inbuilt battery "overprovisioing" so the battery in fact is charged max to 80% ?
    Anyone has some insight in the matter?

    itll be fine. no way to change charging options. just do a full drain and charge once a month or so, as per apple recommendations.
