Yes, using a laptop for over 10 hours on battery is not for people who do any serious work needing a pro laptop - what is in the professional circle called a workstation. Glad you understand. Note apple's stated hours: 11 hours while browsing the internet, and 17 hours for watching videos. If this is your use case, you are not the target market for a workstation. Apple sells "pro" laptops like Kia sells racing cars.
