Why does my iPhone randomly dim itself?

I've had this issue for quite awhile. It's an iPhone 5 with all recent updates. I've looked up how to fix it, and so far nothing's worked. Auto brightness is turned off, white point is off, and I've reset all my settings. My brightness is turned all the way up, but when I move the slider past halfway it stops getting brighter. Some days it won't dim at all, other times it seems to spend most of the day dim.

It is conserving the battery life

  • Why is my Wi-Fi bar grey or dim on my iPhone 4S? I just got an iPhone 4S from a girl and after I set it all up (it's not on a plan) and the Wi-Fi bar is grey/dim and I can't connect to Wi-Fi anywhere and I can't slide it.
  • Why does the brightness on my iPhone 5s dim randomly? I've had my iPhone 5s since November and I've noticed that the screen occasionally dims a bit when it's on full brightness. It's not a huge issue at all, in fact when it dims it's barely noticeable, but it's just been annoying me lately. Does this happen to anyone else with an iPhone 5s? Other than this issue my phone is perfect. And I've also turned auto-brightness off so that's not the issue.
  • Why does my iphone 5s randomly restart by itself? My iphone 5s has been randomly restaring for about 2 weeks now on its own. I tried resetting my settings to see if it would fix the problem, but it didn't. The phone is new. What can be causing this? I'm running iOS 8.3 btw
  • Why are people who have owned more than two iphones so dim? Srsly. They are dimmer than a lightbulb still in its packing. They are dimmer than my dog's butthole. I haven't actually checked, but I ****ume that it's pretty dark in there.
