Macbook Air M2 Battery Draining
I got recently Macbook Air M2 8c cpu, 10c gpu, 512gb, 8gb RAM. Using it for normal business activities (MS office apps, web browsing, video calls) without connecting to any external monitors (just my iPhone and magic mouse 2 occasionally).
The battery performance is great when it's 60-100% charged (it drops 6% for each 1 hour of video calls using MS Teams), but when its less than 60% charged it drains much faster (20% drop per 1 hour of video call using MS Teams).
Other friends using the same specs said they have not seen this issue on their Macs and their batteries last good 15-18 hours. In my case it's 10 hours only with 12 hours if I'm using low power mode.
Is this behavior normal or it's a defect ?
P.S. Already checked battery health setup from the settings and it shows 100%. No apps are shown as energy intensive.
MacBook Air, macOS 13.1
