xps 9310 battery drain after update intel wifi/bluetooth driver
XPS 13 9310
I have been using xps 9310 for a year without draining issue.
Recently I found battery drain after I update some driver including killer software, intel wifi/bluetooth and etc. Battery drain at night while I close the lid. I run powercfg /sleepstudy and found that Intel(R) Wireless Bluetooth(R) (USB\VID_8087&PID_0026&REV_0002) (FDO) cause the drain. I wonder how to fix this. Thanks

The problem is solved. Root cause is intel bluetooth drive that just release late 2022. I remove intel bluetooth driver from windows 10 app removal and disable/enable bluetooth in windows settting. Then the battery drain from bluetooth device is gone.

The XPS 13 9365 2-in-1 notebook supports the Modern Standby mode, this mode is what keeps the system switched on and is what responds instantly if the power idle mode is configured and connected standby enabled. This can cause the system have more battery drain than the traditional the S3/S4 power mode.
