Seems like a bit of wasted negative thinking (imho and with due respect). Yes a percentage number is certainly a bit easier to comprehend but we’ve all survived, even thrived?, prior to iOS 16/a battery percentage.
This may be a bit of a labored comparison but consider a watch face has only the number 3, 6, 9 and 12 on it. When the hands are between 6 and 9, having to estimate the time is 7:35 based on where the hands are isn’t something I put on my “today’s major problems” list.
Now Apple fixing Apple Music playing, occasionally, on my HomePods instead of where they should be playing on my AirPods? That is! on my “today’s major problem” list!
