The battery is draining in the MacBook Pro 2019 when the adapter is plugged in, what's the problem?

Question

macbook

Good afternoon!
Tell me what's the problem? When you turn on the macbook 2019 pro, the battery starts to run down, when the charge reaches 85-90%, the battery starts charging to 100% and then the charge does not drop, this happens every time I turn off the poppy. The laptop is on all the time. Restarting, clearing memory, cache does not help. The previous model of the 2015 proshka did not suffer from a similar phenomenon. What can be done so that the battery does not discharge when plugged in? Thank you.
