MacBook Air m4 battery discharging fast after visiting Genius Bar

I went to Apple's Genius Bar to get my MacBook's screen checked. The person who checked my MacBook opened the BIOS menu (if I am not wrong) and inspected the peripherals through a server. Although the experience was very amazing and fast, but I am noticing fast battery drain after that. My typical work is light to moderate and it includes reading documents, coding and watching youtube videos usually at 1080p or 720p. My work environment is cool.

Is it normal ?

( I charged my MacBook to 86% today )

What I've noticed so far:

1. Spotlight keeps running and it is not shown in the screenshot
2. WhatsApp, which consumed around 12.34 power, got uninstalled today.
