Recently, my M1 MBA was draining out of battery very quickly. I lose 50% charge in an hour, losing about 1% in less than a minute. This was surely not the case before. When I click on the battery bar in the top right it shows VScode using a significant battery, but VScode is not even opened. I searched about it a little and found out that there are some third-party apps preventing it from sleeping.

when i enter pmset -g in the terminal, I get this

System-wide power settings:
Currently in use:
 hibernatemode        3
 powernap             1
 disksleep            10
 sleep                1 (sleep prevented by powerd)
 Sleep On Power Button 1
 ttyskeepawake        1
 hibernatefile        /var/vm/sleepimage
 tcpkeepalive         1
 standby              1
 displaysleep         2

pmset -g assertions gives this

    Timeout will fire in 120 secs Action=TimeoutActionRelease
No kernel assertions.

Even if i try to kill the PreventUserIdleSystemSleep by using sudo kill 54903, it comes up again with a different pid.

This is really troubling. I got this laptop just for its battery backup and my work really requires it to last at least a day. Any suggestions or solutions would be great. Thanks.
