Note: I use the iPAD Pro 10.5, with iOS 10.3.2. Auto-brightness is not enabled. I am used to adjust the brightness when I watch videos, since some contents are too dark to my taste. Usually I let the brightness to 30%, and when I watch videos in nPlayer (similar to Infuse, another iOS app) I increase this to 50%. As you all know more brightness means more battery wasting. Also more brightness can lead to more eye strain, despite the fact these last iPADs are superior in this regard, quote: *********** And not only is the iPad Pro 9.7 more than 20 percent brighter than the other current iPads, but it is the brightest full size production Tablet that we have seen. And even more important and impressive is that it has by far the lowest screen Reflectance of any mobile display, so its image colors and contrast in high ambient light will appear considerably better than on any other mobile display. *********** I explained with a few tips this whole thing, in this thread: https://forums.macrumors.com/thread...t-night-black-background-for-reading.2051591/ Look into "bias lighting" and what I said about black background for reading. For some 30% might not be enough, for me it's adequate for reading. Now, here's the thing I was going to say: - iOS does not tell us what are the current brightness levels. At least not in this version (don't know about iOS 11). So if I raise to 50 or 70 I can only guess from looking at Control Center these are the current levels. Remember we are always told the percentage left from the battery, and we may also hide this number. But when it comes to brightness I haven't found a way for iOS to display that. The thing is: apps can tell me exactly the % of brightness used. nPlayer or Infuse. There are two apps for iOS that can adjust the brightness: https://itunes.apple.com/app/brightness/id472794243?mt=8 It's this sort of thing I am talking about. The problem I think they have is the fact (if I am not mistaken) iOS messes with the changes done by these apps, once I close the Smart cover and use the iPAD again it's back to the original brightness levels. Example: - My device was using 50% before installing the app. - The app was installed, with 2 settings: 30 and 50%, for me to choose between them. - I select 30. After a while I discovered it was back to 50% without my consent. So what's the issue here? Is this a bug from some specific app or all of them are useless for this task? Sure we can fine tune this setting to what feels best. But what about knowing exactly if it's using 20, 30 or 50%, and make the changes accordingly? I don't get why we can do EXACTLY THAT with volume levels, yet we are unable to do that with brightness. Any thoughts? Perhaps I am using the wrong app or not doing something right. When I tell the app to use 30 or 50% I want to stay that way unless told otherwise, regardless if I turn the iPAD off or not. From the looks of it it seems a specific app or all of them are only enforcing these percentages when active, or iOS is messing with this setting.
