    I just upgraded to iOS 10.3, on my iPhone 7, and did not have this issue *before* my update. Now, I have it all the time- and it is not always battery dependant (although, the change zoom trick always works-temporarily).

    So, not only did the update not resolve the problem for all owners, but it created a problem for many of us.

    Stupid Jobs. Why did he have to go and die?! Now we're left with 'betaware' forever. (Lesson on this is to never try and cure cancer with lettuce...)
    Try Reset All Settings.
    Reset All Settings
    Go to Settings >General >Reset >Reset All Settings. This resets to default everything in Settings, including notifications, alerts, brightness, and clock settings like wake up alarms.

    I have same problem. My 7+ does dims automatically. Just had last 7+ replaced for speaker issues. So new 7+ running 10.3.1 and it dims so dramatically I can barely read the screen. Happens even if phone plugged in. i was below 50% yesterday playing Pokémon Go and it didn't dim. Genius at the bar thought it was some app I had doing it. But it did it in front of genius at the bar with no app running or in the background. Dimmed so low could barely read it.

    After updating to iOS 10.2.1 I have noticed that my iPhone screen gets very dim. I check and I have brightness turned all the way up. Is this a new feature in the update or a bug that needs to be fixed?
    I'm having the same issue. Turned off 'Auto Brightness" in "Display and Brightness". Turned off "Night Shift". Still dimming while I'm using it.

    When in "Low Power Mode" - device will dim, but I turned off 'Low Power Mode" also.

    So, does anybody have an answer to this problem? Or, maybe I missed the answer in the thread....?


    Thank you.

    Do NOT DO A RESET. This deletes many of your emails, photos, and other things. This should only be a LAST RESORT.

    I repeat, do not do a reset.

    Resetting all settings, just as @Ledsteplin recommended, does not remove any content from your device. Emails, photos, and “other things” are left in tact.

    The advice @Ledsteplin gave is perfectly good.

    There's no "fix" because this is "working as intended". Tried going through the Bug Reporting process with Apple, but in the end, it is what it is ("working as intended" was what they said to me). They've tweaked how it works in 10.3.x versus how it worked when the issue originally popped-up in 10.2.1, to mask the screen brightness being limited (aka, they modified the brightness bar in Settings so it now changes the brightness along the entire length of the bar, versus the bar not affecting the brightness beyond 50%/75%, depending on your battery drain), but in terms of screen brightness, it still dims with the battery drain. Super frustrating as it makes the phone near impossible to use outside with sunglasses on (when the phone dips below 50% battery), but other than beating a dead horse, I don't think there's anything we can do.

    My guess is this whole screen brightness limiting was a result of the battery bug "fix" introduced in 10.2.1. But, who knows. All I do know is, it's annoying. I'd rather go back to pre-10.2.1 functionality and have my battery drain faster with full screen brightness...versus not being able to use my phone outside when I drop below 50%.
