Battery drain issue after the latest Catalina Update for 10.15.7, Update was released in Feb 2021.

Battery drain noticed after I updated to the latest Catalina 10.15.7, there was a minor update about 3 days back, and post that I started noticing battery drain again which was corrected in the previous update in Jan 2021. The drain is close to 14% battery lost in 30 mins. That means I will get only 4 hours of Battery life as against 5 hours before this update. The drain is close to 1% every 2 minutes.

Kindly suggest.

It is normal while running on battery after an update for addition battery loss to occur. The System is busy re-indexing all the changes that took place with the update. Suggest running form charger for 1 - 3 days depending on the amount of data is on the drive. It should settled own soon after.
