MacBook Pro 15 Battery Stops Charging When Launching Energy Impact App

When by MacBook pro battery is charged below 80% and is charging, every time I launch an app that creates a short leap at energy impact graph in Activity Monitor, the battery stops charging. Most of the time launching the Safari does that. I have to plug out the charger from the network and plug it in again to continue the charging process. When battery is charged above 80%, the problem disappears.

SMC reset or recalibrating didn’t help. Besides this the battery works just fine, I am able to work for 3-4 hours on one charge.

Full charge capacity is 6388 mAh

Cycle Count: 823

Amperage: 2950

Voltage: 11655

Is it just dying or should there be a fix?

Thank you!
