Android 11 October Security Update drastically drains idle battery usage

**EDIT** Ever since I installed the latest security patch available for my Phone (October 5 patch), there has been insane idle battery usage. More like 1% dropping sequentially whenever I'm sleeping *It's worth noting that, this doesn't happen when the phone is in Airplane mode, or switched off*. I picked up the Paid version of Accu Battery, it doesn't show background battery usage. Better Battery Stats (BBS) was recommended and I went for it but it doesn't work most of the time (shows *No stats have been collected yet*). But I slept for the past 4 hours and it worked, but I need someone the translate it's output for me, so I can recognize what's draining my battery.
