Yeah the 13 resurfaced because the_top_g from reddit said this, from his link:

I appreciate his findings here! Also looking forward to seeing if the 15 plus ends up being better for people than the other 15's as well!
Ah, yeah that's where it came from. Thanks.

Certainly we've heard that not only the regular 13, but that the 13 Mini worked for some who had trouble with others.... but then we heard last year that the 14 and 14 Plus were good for some last year who couldn't even use the 13's- and now some promising news from some on the 15 series.... But someone like me who is not too educated on the science behind these numbers, it's hard to really tell which would be better- some have higher PWM frequency but deeper modulation, and some then like the 15- that has lower modulation (really good numbers actually at 100% and 75% brightness), but the PWM frequency isn't quite as high as the 13- seemingly. So it seems we are still at a point that there is no way to tell other than buying one and trying it out for a week.

I just picked up my regular 15 last night at my local Apple store- will give it a try and am hoping it'll be comfortable or somewhat comfortable as a replacement for my 13 Mini (which seems bothersome at times, not consistently).

I really want it to work for the much improved cameras, extra functionality (2x zoom), the dynamic island, the nicer build (frosted glass), etc.
 
I’ve never really experienced any problems with my iPhone X or iPhone 12 PM but ever since I got my iPhone 15 PM on Friday my eyes have felt really irritated and fatigued.

I haven’t been using the phone any more than my previous phones, in fact I’ve probably used it less because of this reason.

Not sure what in particular has changed screen technology wise that is affecting my eyes but it’s not a nice feeling.

You're welcome and best of luck with the 15!

Hmm.... have others out there found the 12 series to be somehow more tolerable?

I remember I bought a 12 Mini at launch, and had it for a year- surprisingly I had no issues with it at all. I was sensitive to the flicker on the XS that I had tried a year before, and have been questionable on my sensitivity to subsequent phones (13 Pro, then 13 Mini) that I have had since the 12 Mini.

I get frequent headaches anyway (going back to even before smartphones)- which don't seem to be associated most of the time with phone usage. Sometimes I'll go a week with only quick glances at the phone from time to time, and doing any other media consumption/browsing on my old MacBook Air 2015, which is comfortable to the eyes, but I'll still have headaches. Then I'll go a nice couple of week stretch with almost no headaches- even if I do use the phone during that period.
But I think there were times with the 13 Pro and are times with the 13 Mini I've had for the last year- that there is some discomfort, my left eye starts to hurt after a few minutes of using the device and a headache can develop after (though not always).

It's hard to put my finger on it though because there have been other times when I would use the 13 Mini for an hour or more and not have issues. Maybe it's better during the day with a lot more light in the house, and maybe the headaches or eye pain are not related to PWM since it's not every time I use the phone- maybe it's my corrective lens prescription that needs to be updated because I am finding now over the last couple of years that it's more and more difficult to focus on things up close (I need bifocals), so maybe using the phone is just on that borderline distance where my eyes are straining more now to read than was the case back in 2020 when I had the 12 Mini?

Hard to say- but it's interesting when you mentioned the 12 series and I remembered having zero issues with that 12 Mini, even though on paper it was a much worse device for PWM frequency than my 13 Mini, 13 Pro, or the 15 series.

I definitely notice some reaction though to certain phones. My wife's XS Max makes me feel woozy soon after looking at it. And last year I tried a 14 Pro, and though it didn't cause headaches directly- my eyes felt like they were sort of "sizzling" when I'd use it. Going back to the 13 Pro I had at the time was much more comfortable.

Moto G54 5G coming to the USA

120hz LCD screen. 405ppi, 6.5”


Looks great. I wonder if the LCD displays on these are problematic at all for some people like Apple's LCD"s are? Or is Apple just pushing crazy magic that nobody else does to theirs to try to make the colors look better?

It would be a problem for me to try to get out of the Apple ecosystem, but a phone like this would be so nice.
 
Been using the 15 Plus for a little over a day now and my eyes do not feel that good. I have one eye that's more sensitive than the other and it's definitely bothering now after using the phone for an hour straight. I do like having a 5g phone so I might have to get the SE even though it's smaller than the XR which I could still use on WIFI at home.
 
Is there any other product made on earth that causes a significant number of people so much unintentional pain? - like iPhones do?
I can’t think of anything I’ve encountered in my entire life that’s as potentially hazardous as an iPhone - except chemicals which come with warnings.
 
Def gonna go down the line of buying a used 13 or 14 and have the screen replaced for an LCD.

Local shop near to me has quoted £85 for supplying screen and fitting.

He has warned of possible issues but has done it a few times before (mainly for cost reasons LCD v OLED) and never had anyone come back with issues

tbh i was going to do this

But my iPhone 11 started hurting my eyes so im back on iPhone 8

What if you do all that and still have strains

Yes, when I got my 11 at launch back in 2019 I had a pain/pressure behind my left eye when I used it that persisted for the first month or so.
I brushed it off thinking that this phone did not have OLED, it may have just been "in my head" because I had just tried an XS the year before that didn't work out because of PWM, and I may have just had that on my mind.

Eventually I got past that and it was fine, until the last couple of months about a year later when it became occasionally uncomfortable- something that NEVER happened with the 6s and 7 phones I had before it.

I miss those phones- so incredibly comfortable to look at, I could spend so much time on them with no issues at all.

How easy is this to fix on Iphones?

Appreciate they could just bring out an LCD version of new phones (ala Iphone 11) but how can this be fixed whilst still using an OLED? Surely if it were that easy, such as a software change you can enable/disable Apple or Samsung would have done this ages ago, especially being the first to announce as it would pull more people to their new products.

My understanding is it is not a trivial fix. With LCD you can change the brightness by adjusting the current. When you adjust the current with OLED though, you alter the color…which then requires further compensations in the circuit. Combine that with the fact that PWM helps improve battery life and there is very little motivation for companies to try and work a fix for this.

I am just hoping microLED doesn’t continue the PWM trend.

How bad is the miniLED (and it's very high frequency PWM) on the iPad Pro for folks here, as opposed to what we see with OLED?

But to your other point- I have seen that as well as to why some manufacturers tried doing DC Dimming on Android phones and then stopped for a while.... they are so worried about colors being impacted, and that it would give them a bad name, so to speak, having displays with "off" colors.

Quite frankly I'd be happy with true DC dimming even if it did mess up the colors a bit on my phone.

I’ve read this many times before, but it always makes me wonder why OLED TVs don’t use PWM.
 
So iPhones do have a warning...

Medical conditions.

If you have any medical condition or experience symptoms that you believe could be affected by iPhone or flashing lights (for example, seizures, blackouts, eyestrain, or headaches), consult with your physician prior to using iPhone.” Says Apple.


 
I’ve read this many times before, but it always makes me wonder why OLED TVs don’t use PWM.

I think the main reason is the difference between max and min brightness on TVs is very very small - compared to the max/min brightness on phones. And even with that, if you search TV color calibration forums, you will find people endlessly complaining about how bad the color accuracy is on OLED TVs at low brightness levels.

That said, OLED TVs do now use a kind of PWM when dimming as well. It just has a shallower dip (it doesn’t go all the way off, so I guess technically not PWM, but they do have a dip in brightness output that causes a flickering that bothers some people). This is true for both LG and Samsung panels anyway.

LG doesn't use PWM in their OLED TVs.

The LG C1 doesn't have a traditional backlight, and it doesn't use pulse-width modulation to dim each pixel, but it's not flicker-free, either. Like all OLEDs, there's a slight dip in brightness that corresponds to the TV's refresh cycle. This dip exists on every OLED we've tested, and unlike PWM, it's one line at a time instead of the entire backlight, so it's not noticeable at all.

I've owned multiple LG OLED TVs and they are fantastic. Highly recommended.

I only owned LG CX and it was giving me headaches. No nausea or blurry vision like the iPhone only headaches. Sold it after 2 weeks.

There are many variables, as I’m sure you know, but hopefully you were not using HDR. The brightness alone on those TVs can give anyone headaches. I am sorry you had that experience.
