If youre looking for a plug and play zephyr proect there is a battery management lib i haver created on github for the XIAO BLE board:
https://github.com/Tjoms99/xiao_sense_nrf52840_battery_lib

Here you can read the battery voltage and charge it using the usb cable, enjoy! Feel free to leave feedback

I am using XIAO_52840 (not sense) board and using nrfutil runner for flashing. After flashing command, I get below error.

-- west flash: using runner uf2
WARNING: runners.uf2: Discovered UF2 partitions don't match Board-ID 'Seeed_XIAO_nRF52840_Sense'
FATAL ERROR: No matching UF2 partitions found

Please guide how to resolve the issue.

Weird. Mine came with Xiao Sense firmware and it worked until I accidentally overwritten internal flash and had to reupload firmware using Raspberry Pi Pico and SWD interface. I solved this problem by uploading Sense firmware again. Board-ID is hardcoded somewhere in Zephyr's board definition file. I'm not sure how much firmwares differ with exception of USB ID and few strings. I already posted this to nRF wiki
