iPhone 17 pro max display darker than 15 pro max

I have 17 pro and 14 pro, and I instantly noticed this issue also. The main difference is at lowest brightness points, however I think it might be due to the new iphones having 1nits lowest brightness points. This means sliders aren’t comparable. You have to raise them on 17 more.

The 3000 nits is achieved only with auto brightness in outdoors, whilst the slider max values should be roughly similair aka 1600 vs 2000. At max brightness I do see a slightly brighter screen on my 17 pro.

Not sure why supporters didn’t tell you that, but if you check phone specifications specifically advertised display spec, you will see the new phones mentioned 1nits lowest brightness point, so almost turning off completely. And you can see clearly that outdoor only is when 3000nits activates, that’s also officialy written on spec pages. The normal nits aka indoor are rougly the same. Think maybe not all supporters are aware? After I raised slider a tiny bit the brightness is now comparable, and at max value its brighter then the 14 pro, specially outside.

Same issue here. The screen is so dim to the point that I can’t even see it outside. An no it is not overheated. Even indoors I have to keep the screen on 100 percent brightness to achieve the same brightness as 70 percent on my 16PM. On top of that, there is this very awful blue green tint when viewing the screen slightly off angle which even the demo units at the Apple Store have it.

Try turning off "Auto-Brightness"

Mine is not pro max but iPhone 17 base model but I have experienced exactly same thing. Now I am compare my current iPhone 17 and iPhone 16 Pro max and even though iPhone max brightness is up to 3000 nits on paper (16 pro max is up to 2000 nits), my iPhone 17 base model is a lot darker!!! It is frustrating and I though it happens only me

Same or similar problem here. I always use auto brightness on my iPhones without ever changing brightness manually. Where on my previous iPhones up to the iPhone 15 Pro auto brightness was perfect for me with my new iPhone 17 auto brightness in certain lighting conditions is way dimmer so I have to adjust manually.

Peak brightness in sunlight however is perfect. It’s just in certain conditions indoors when there’s no direct light source shining on the sensor the screen is noticeably dimmer than on the iPhone 15 pro so I have to adjust manually. I bet after a couple days auto brightness will know what my preferences are but it’s just something I noticed.

I noticed the same thing and I also had a 15 pm and now have a 17 pm.

I have the same issue with my base iphone 17, compared it to my previous base galaxy s23 it is so much brighter and it’s maximum advertised nits is only 1000!
