Unfortunately, today it is impossible to buy a mid-range or high-end smartphone with a decent IPS matrix (contrast from 1500: 1). Alas, manufacturers essentially do not care about those who hang behind the screens of smartphones for a long time - and there are a lot of them. It seems to me that the problem is not of great concern to manufacturers for a simple reason - most people have a slow nervous system, and those who have a fast (i.e., the most sensitive) somehow solve this problem by ignoring smartphones with AMOLED or choosing models with DC Dimming and sacrificing drop "deep black" because of this.
The main reason is consumption at medium brightness and the impossibility of a flexible screen for IPS. Plus impossible to release "Instant On" feature on IPS.
AMOLED cannot be made with high-frequency PWM - they simply burn out faster in this mode or the color balance is greatly disturbed vs IPS.
At high screen brightness or white(light) screen theme, IPS panels are actually more energy efficient panels. And they do not flicker thanks to the high-frequency PWM, while having a parallel resource 2-3 times higher than a typical AMOLED.
It is strange that the author of the review writes about 4k@30Hz maximum, although it is written everywhere that 4k@60Hz is supported on the rear and selfie cameras as old model.
Of course, it is disappointing that 4k is supposedly disabled on the model with 128GB (they are quite enough to make videos for 2-5 minutes for several shot series). And there is no 6k-8k resolution in the video, because it allows you to remaster with post-effects in 4k right away.
Well, for such a heavy smartphone, the 3200 battery looks like a mockery. Other pieces of hardware inside, due to their weight, did not allow Apple to install the usual 5000-5500mAh for such sizes.
Judging by the fact that Apple, despite the flickering screen, sells smartphones in tens of millions, the problem of eye fatigue during prolonged reading of information from the screen is of little concern to the majority of the public. The damage to the eyes and nervous system is still, of course, inflicted latently, but this affects slowly, like smoking tobacco.
Unfortunately, there is apparently no hope for microLED - there will most likely also be low-frequency PWM due to very small LEDs and the same sharp drop in their resource as in organic ones. So I don't know where this will lead us all. Of course, my condolences to the owners of the fast nervous system.
PS,
And again, I see incorrect data on the minimum consumption, which simply do not fit in with the battery capacity. Just take the battery capacity in watt-hours as about 12Wh, i.e. approximately 43000 joules and divide by 0.56W (for one second or 0.56 joule) of the supposedly "minimum" consumption ... we get approximately 76700 seconds of operation in this mode. Or about 76500/3600 - 21-22 hours in "reader/idle" mode maximum. The author assures that in this mode the smartphone lasts as much as 2660 minutes or 44 hours! How is this possible, author? Do you know math? If you know, you should recalculate the minimum consumption at least twice from what you measured ...
