Hi abhinavmishragoa,
If there are battery drain issues in sleep mode, in order for us to verify, please kindly follow the steps below and show us the screenshots.
1) Charge the phone to 100% and remove the charger before going to bed > Clear all apps in recent app list >  turn off screen > the next morning before using the phone, please screenshot the two pages:
a) Settings > Battery
b) Settings > Battery > ""Advanced battery usage"" (tap the battery icon to access)
Thank you .

See I charged it to 100% last night then put it in airplane mode before going to sleep like always didn't use it a bit after that till morning but battery dropped to 66% without phone usage.
Why is it happening like this after last update?

Show app usage. Check which app drains more. Check memory usage under developer options of running processes.
Presence of a bad app, update all apps.
Try backup and reset as last resort.
