I used more or less non stop my new Macbook Pro M1 for about 7 hours and noticed that at the end of the day the battery was already at 14% despite the fact it was fully charged when I started working.
While working I was using a second monitor, a wired keyboard, a wireless mouse and a USB hub. The programs I actively used that day were Safari, Chrome, Sublime Text and iTerm2. Safari, Chrome and Sublime were constantly using more or less 500 MB of RAM.
Apple said the new M1 had an autonomy of 20 hours so I'm a bit surprised that after only 7 hours of work it is already at 14%. Is this suppose to be normal? Is it the same for everyone out there?
