Yes, same here.
It seems/feels like the new series x controller uses twice as much.
I used an official Microsoft recharge pack. The same pack in an xbox one controller lasts at least twice as long maybe even longer.
I have to say I am using the the controllers on PC occasionally, maybe 1-2h a day, 3-5 days a week.
The new xbox controller had to be recharged after two days, while the xbox one is recharged after maybe 10-12 days, depending on use.
It seems like the new controller drains battery while turned "off" maybe it's an issue with Bluetooth?
Anyway, the new xbox controller is very new, I have to test it further, maybe using a stopwatch to count my usage and compare with my old controller
