MBP 9,2 waking from sleep/hibernate

So, I have a mid-2012 13" MacBook Pro running Sonoma 14.2.1 and OCLP 1.3.0.

My battery averages on 2 hours per charge, which is fine by me considering its age. But if I put it to sleep (by closing the lid) while on battery power, e.g., overnight, the battery is depleted the next morning. As if it was awakening frequently or something like that. Haven't seen the Apple logo light up or anything like that, so far.

Any ideas on what may be the culprit and how to solve the issue?
