Hello. I'm on my second unit of 16 Plus. The first one had a bad screen (brightness was terrible as a Genius stated) so I had a replacement. Today I went back to the Apple Store to check if my new unit had the same problem. After comparing mine with a 16 Plus on display, I noticed mine was again less bright with same settings...but one that I never thought of: Auto brightness in Accessibility. The 16 on the display had its setting turned off, mine was on. The same Genius then told me Apple "has the OS tweaked for the phones on displays to make them pop and sell more". Can't believe I was told that but actually turning Auto brightness Off makes the screen illuminate. Which is bad for the battery as per the warning. Why would Apple do that? The Genius told me he found this information cause many customers came back with the same problem as me and they were replacing them each time. One could ever say he was a bit authoritative and even said I was probably lucky. What do you think?
