Hello!

I have been using the 13" MacBook Pro 2020 (non-M1) for 6 months and have noticed that the battery life performance has been significantly less than what was advertised. On a full charge, my mac will last for about 4 hours even though the only apps running are safari (not video streaming), notes, and OneNote. I made sure to close any unused apps and turn off unnecessary connections (such as bluetooth). Many reviews report at least 7-8 hours of use under similar circumstances.

Here is some other information about the mac:

MacOS: 11.1

Battery cycle count: 149

Battery condition: normal

Optimised battery charging

Automatic brightness: on

I usually leave my mac plugged in during use, for several hours at a time. Could this have caused the loss in battery life? Please advise me on what could be the cause of the shortened battery life and how I can fix that. Thank you!

My battery runtime is low
