Hello Karolina,
Welcome to Microsoft Community.
If you have about 80% of your battery life left, your battery is in fact reaching its limit.
I recommend you try a few things for battery drive first:
- Plug in your Surface Go 3.
- Select Search on the taskbar, enter device manager, and then select Device Manager from the list of results.
- Select the arrow next to the Batteries category.
- Double-tap or double-click Microsoft Surface ACPI-Compliant Control Method Battery or Surface Battery, select the Driver tab, and select Uninstall Device > OK.
You can also right-click Microsoft Surface ACPI-Compliant Battery or Surface Battery, and then select Uninstall device. 5. Select the computer at the top of all the categories, select the Action menu, and then select Scan for hardware changes. 6. Select Start > Power > Restart.
Once you've finished rebooting, charge your Surface Go 2 again and watch for any more rapid depletion.
If the situation of rapid battery depletion remains unchanged, then perhaps I should recommend that you send your Surface device to Surafce technical support team for inspection or repair:

I wish you all the best.
