    What do you think? Will Dark Mode save battery life? It makes since to me, but what will happen in real life? Is anyone here from the Android world that can give some insite?

    Probably yes, but the effect is less tangible than you would expect.

    It has the potential to extend battery life slightly on OLED devices (X, Xs & Xs Max) depending on how it is used. On LCD panels the opposite is actually true as more energy is required to display a dark image (unlikely that users would notice a difference on LCD panels when it comes to battery life though as the majority of the energy in the screen is used by the backlight, which is illuminated regardless of whether you are displaying mostly black or mostly white... and the best way to reduce power consumption is to turn down the brightness).

    Not that you would be able to notice. Negligible at best.

    Someone will definitely try it, but we probably won't know for sure until the final release.

    It’ll make a tremendous difference! Just don’t go enabling it on an iPad as LCD’s are more efficient with all white backgrounds.

    Dark mode definitely does help battery life with an OLED screen. LCD, no.

    Yeah, max brightness. Who uses iPhone with full brightness for a long time anyway?
    And, turning on greyscale could also save more battery. Greyscale can also help you from addicting to the iPhone.

    Probably to a negligible extent, and only on OLED (X, Xs, Xs Max) models.

    True Dark mode increases SOT by 40%.
    Apple’s Dark Mode is a gimmick however and won’t make much difference. Maybe 2-5%?

    Well, what is “true dark mode” then?

    True dark mode = turn your phone off

    If it's true black, then maybe there are some improvements, but if it's greyish or something, don't expect any change.

    it is greyish. Just some real black borders here and there.
    (am running the beta for about 6 hours now)

    But for 70%/80% its greyish. So not a real/true Dark Mode as seen as on several Android devices with Dark Mode enabled.

    I’m not sure how much I plan to use ‘Dark mode’ that it would impact my battery life as it is. If someone wants impacted battery life, make adjustments to your settings and usage, that’s where you notice the biggest difference. Also, where I also noticed battery improvements is using ‘low Power mode’ all the time, it does interfere with the processing power and slightly dims the display, but it does seem to make an impact in that respect.

    id imagine system wide including third party apps would be true dark mode. Safari is still mostly white because of the web pages.

    It will for OLED devices yes.

    I have Noctis and eclipse on my iPhone X and I get about 20% extra battery at the end of my day vs no dark mode with same useage.

    Ah well that sucks then. In some pics it looked like it would have true blacks

    From what i have seen the dark mode from android and IOS looks about the same to me...wether it’s grey or full on black it does the job required that’s for sure.
