Your laptop is five years old. It's likely that the battery is failing and near end of life. That battery is rated for 300 discharge/charge cycles, and you are likely beyond that.
You can test the battery:
Open an Administrator CMD prompt (CMD, run as Administrator). Paste this command, and then press Enter: powercfg /batteryreport
That will show a figure for the designed battery capacity (when new) and the current ("full charge") capacity.
You can also run Dell Diagnostics: Immediately after pressing the power button to turn on the laptop (or after clicking the Reboot command), press and hold F12 to enter the One Time Boot Menu, select Diagnostics and press Enter. The Dell Diagnostics will test major hardware components. Choose to run the extended tests.
Though I expect that your battery is the issue, you could try a reset:
Disconnect all peripherals: printers; USB devices; media cards; USB hubs and extenders; etc.
Disconnect the AC adapter.
Disconnect the battery.
Press and hold the power button for 30 seconds to discharge any residual electricity.
I have the exact same problem also with the Alienware 17 r5 (i9-8950HK and a GTX 1080), except that I can run it on battery a bit longer, before the battery level jumps from let's say 90% to 5%.
I already tried a new battery with the same behaviour. The Battery readings are totally wrong ,and yes I already calibrated the battery multiple times as well as reset the BIOS without success.
My BIOS is the latest version 1.20.
I suspect it is a BIOS problem, because that behaviour was reported in older threads as well and it seems to be tied to wrong battery readings.
For instance, I can use my battery beyond 0% for several hours. As mentioned above, recalibrating the battery won't help, because once fully charged it will jump from high battery level to low again, thus causing wrong battery readings yet again.

Dell has genuine Dell batteries available to order for your model. Parts-People is a reliable source of genuine Dell parts, However, they don't have your battery in stock.
You can also run Dell Diagnostics:
Immediately after pressing the power button to turn on the laptop (or after clicking the Reboot command), press and hold F12 to enter the One Time Boot Menu, select Diagnostics and press Enter. The Dell Diagnostics will test major hardware components. Choose to run the extended tests.

Here is the report, everything seems to be showing the battery is still good. I will try doing a reset to see if that has any effect.
