What you describe sounds like normal behavior. By default Windows will switch to a lower-performing power plan when the laptop is unplugged, in order to prolong battery life. You should be able to assign a different power plan in Settings, and/or customize your power plan(s) to your liking.

I think you didn't get my problem,
it's the opposite of what you said.
when the battery is put in the performance is good with the charger 
when unplugging the battery the performance dropdown.

of my think, it's like a bridge of electricity or something like that.

Your charger may not be providing adequate wattage/failing. Check the DC side cable if there are any sharp bends/folds, or variations on the rubber shielding, or if you can feel the thinner wires buldging beneath outside rubber.
As a result system maybe drawing power from both battery & adapter to compensate.

Try with a different charger or higher wattage charger of same barrel size/usb c

You're right, I misunderstood. But you're saying that the machine slows down when you run plugged in, but with the battery removed, right? (I won't ask why.)

What version of Windows are you running ("winver")?

I don't have a Dell laptop, but I have an old ThinkPad with an external battery running Win 10. If I check the power plan by clicking the battery icon, and then remove the battery, the system detects that the battery is gone but the power plan / slider stays the same. Is the same true on your system, or are the settings changing when you remove the battery?

Also... do you have "Dell Command | Power Manager" installed? It's in the list of "Drivers & Downloads." I must admit I don't know anything about it nor do I have a way of testing it, but it will certainly (potentially at least) change how the system responds to power events, relative to leaving power management to Windows. (I think that hardware vendors' software add-ons are generally lower-quality than Windows.)
