Re: iPhone 6 backlight dimming on its own
Well, I havent used any iPhone's till now. Have been a big fan of Android and specially the Samsung Galaxy series. I own the Galaxy Note 2 smartphone and I have noticed that when my battery is below 15% then no matter what I do the brightness of my smartphone's screen will always dim automatically, even if the auto-brightness bar is at full 100%. So what I get from it is to save the battery from extensive usage the phone might be auto setting the brightness to a low percentage than the actual. This same thing might be happening with your iPhone's as well.
