    Since updating my iPhone 4S to 6.1.3 my Auto-Brightness no longer works properly.

    I normally set it by going into a dark room (or putting my finger over the ambient light sensor), adjusting the brightness, then turning it on. Usually it adjusts to my environment perfectly, but since updating it no longer does.

    I can hold the phone with the sensor directly under a very bright light, & the brightness bar doesn't move across like it normally does. If I'm outside, I can manually increase the brightness but if I lock the phone & put it in my pocket, when I take it out it's back down to the darkest setting & doesn't re-adjust automatically.

    This issue, plus my battery life disappearing before my very eyes has me really hoping that Apple releases 6.1.4 with a bug fix VERY soon.

    Has anyone else had this problem?

    I have not heard about this problem as an "official" one, the problem that lots of people are facing. May be there is an issue with your software. Have you tried to restore the settings and reupdate it?

    I read something about this on iMore. However, I haven't had this problem. Did you try a reset and re-adjust the brightness setting?

    I haven't seen much on this issue yet. Give Apple a call and see if they have any fix for it yet. I'll keep my eyes open as well.

    Update: So I did a hard reset which has fixed the Auto-Brightness problem, but my battery life is as bad as ever.

    I also tried turning off my mail & iCloud settings, hard resetting, then turning them all back on as someone suggested in Apple Support Communities but that hasn't fixed the problem at all

    I also have the brightness problem on my 4S. By hard reset do you folks mean resetting my phone back to factory settings then restoring from iCloud?

    A hard reset is when you clear all apps from the multitasking bar, then press & hold the power & home buttons simultaneously until the Apple logo appears, & the device switches off.

    I've never been so mad after updating until 6.1.3 came out! My battery life is horrid I can only usually get 2-3 hours usage.

    I recommend that you connect your device to your computer, initiate its iTunes app and restore your device as new. Do not restore from a backup.

    The only reason I don't do it that way it because I have app data that I'd really hate to lose (games)

    An hour later, after reading a couple of longform articles on Instapaper I was down to 60% & it was a steady decline from there, unfortunately...
