Thanks for the detailed bug report. I suspect the low polling frequency
has more to do with the kernel than with bluez, so reassigning there.
That is, unless the problem is one of interference. Please try moving
away from any strong 2.4GHz wifi access points and turning off other
bluetooth devices. Please also try a non-Linux device if you can find
one.

Title:
Lenovo Yoga mouse is slow & laggy in bluetooth mode (low polling
frequency)
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hello,
I have an issue with a lenovo yoga mouse.
This mouse has 2 working mode either bluetooth or with a provided usb dongle.
USB dongle works fine, but bluetooth don't.
Cursor is slow and laggy.
"evhz" (https://gitlab.com/iankelling/evhz) reports 22Hz in bluetooth mouse
while USB mode and other mouse reports 125Hz.
Polling speed is too slow.
I tried different howto suggesting to change usbhid mousepoll value => does
not help.
The mouse seems handled by btusb module, not usbhid (modprobe -r usbhid
killed my other mouse, but not the lenovo, while modprobe -r btusb killed the
lenovo).
I tried 2 laptops (XPS9370 with 18.04, kernel 4.18 and kernek 5.07 and
an older dell Precision M6400 16.04 kernel 4.15).
Bluetooth pairing works well, either with gnome bluetooth interface or
with "bluetoothctl"
Both laptops reports ~20-22Hz polling speed with evhz (and same laggy
behavior)
I also tried 2 bluetooth interface on the XPS13 9370 : the integrated
bluetooth and a Sabrent USB Bluetooth 4.0 (to connect with the
Sabrent, I have switched off integrated bluetooth with rfkill).
