Hi everyone,

My Flip 3's battery has been draining like a brick, I've found out this is partially due to an app I use not ever allowing the phone to sleep (I had it on "unrestricted", but will contact the developers and disallow background usage until fixed).

However that aside, a lot seems to be taken up by a process called "cnss_diag"

Code:
PID USER         PR  NI VIRT  RES  SHR S[%CPU] %MEM     TIME+ ARGS
1590 system       20   0  12G 3.1M 1.9M S  2.3   0.0 168:51.29 cnss_diag -q -f -t HELIUM

This process has been using 169 minutes of CPU time so far, and my phone has only been on for 3.5 days or so:

Code:
b2q:/ $ uptime
 13:02:19 up 3 days, 13:01,  0 users,  load average: 0.04, 0.36, 0.90

As far as I can find, this is an diagnostic utility and serves no purpose for general users. Why is this running? (and can I disable it in a way without root?)

Any other users experiencing this on the latest firmware F711BXXS4EWD9? (One UI 5.1, Sec. Patch 1 May '23)?

Tips are appriciated :)
