This is a solid post. And I don’t necessarily disagree with the Raw data that Apple claims, Various YouTube videos, etc. Now, anecdotal data is a totally different subject that has just as much credibility in a lot of ways, because of all the tweaks/settings that can be adjusted with battery life. There was a thread that I had discussion with another regular member, [which I can’t find, but will post here if I do] but we were having a similar discussion where he did mention he/she owned both iPhone 11/Pro-Max and he was achieving slightly better battery life with the 11.
On a sidenote:
And I realize this is an entirely relevant to the iPhone, but as a stainless Apple Watch owner, the Apple Watch is ready at ~18 hours, a lot of members can achieve well over that, and other members say that’s BS, when they can’t even exceed 18 hours. But with certain apps, settings and adjustments, I can achieve 24 hours, if not slightly better. So what’s my point? It goes back to the realm of what I said from the beginning, it really depends on how you use your phone and what for in terms of media/tasking/apps, etc. Just because of what Apple claims or a’ YouTube’ video, isnt indicative of everybody else’s experience in terms of what they achieve for battery life.
