I've recently got a big screen "dell U3421WE". It works great as I can finally save a charger and charging cable. It's all because this display can provide you the power. In the official specs it says:

your monitor serves as a productivity hub that delivers stable Etherneti and up to 90W of power delivery—all in a clutter-free setup.

But it's weird that since using this feature and removing my original charger. I noticed that my battery has never reached 100%. For instance:

I have never removed the USB-C cable between my display and MBP, so it's always charging.

Is there anything wrong? Should I put back the original 96W Apple charger?

Updates:

I noticed that my display's voltage is 90W and the Mac's official charger is 96W. Is that a problem I should take care of?
