Hi All, first time poster here and 1y owner of a MacBook 12" (2017).
I came to these forums a while back looking for some documented battery benchmarks for the MacBook 12 (2017) and couldn't really find anything that I could replicate myself for comparison sake.
Yesterday I finally decided to run my own web video test and thought I'd share my system info, test environment and results for anyone curious or concerned about their MacBook 12" battery life.
