Have you ever heard of PWM (pulse width modulation)? Even if you haven\u2019t, this screen flickering issue still might impact you. But iPhone 17 looks like it will bring a long-awaited PWM fix.<\/p>\n

PWM can be disabled on iPhone 17 models<\/p>\n

I had never heard the term PWM before today, but as I learned by visiting the \u2018PWM Sensitive\u2019 subreddit<\/a>\u2014which has 16k weekly visitors\u2014it\u2019s a fairly widespread issue, and has been for years.<\/p>\n

Pulse width modulation is a tactic used by smartphones when brightness is reduced.<\/p>\n

Essentially, the phone\u2019s OLED display keeps all pixels on at 100% brightness, but at 50% brightness it\u2019s rapidly switching them on and off in a way that most users can\u2019t discern.<\/p>\n

For some people, however, PWM might result in a screen flickering effect that can cause eyestrain and even severe headaches.<\/p>\n

It turns out, Apple has a solution coming with the iPhone 17, as discovered by Aaron Perris<\/a>.<\/p>\n

The iPhone 17 Pro (and maybe other models) have a new setting to disable PWM:<\/p>\n

\u201cDisables pulse width modulation to provide a different way to dim the OLED display, which can create a smoother display output at low brightness levels. Disabling PWM may affect low brightness display\u2026<\/p>\n

Perris later confirmed that the new setting is indeed coming to the entire iPhone 17 lineup, as reported by MacRumors<\/a>.<\/p>\n

It\u2019s unclear why the new PWM setting is exclusive to iPhone 17 models, but it may have to do with advancements in the A19 and A19 Pro chips.<\/p>\n

In any case, if PWM is an issue for you, Apple may have just given you yet another reason<\/a> to upgrade to an iPhone 17.<\/p>\n

Do you struggle with PWM, and if so, how significant will iPhone 17\u2019s new Settings toggle be for you? Let us know in the comments.<\/p>\n
