On release I purchased a Pixel 4 and gave it an honest-to-god try for a week. The battery issues really were as bad as the reviewers said they were. I needed a phone with the best camera available and sufficient battery life to handle an overseas vacation, and the Android ecosystem at the time had fallen so far behind Apple that I actually jumped ship from Android to iOS.

So quite literally, Pixel 4 is what caused Google to lose me as an Android user.
