I had an aversion to auto-brightness but I decided to give it a go and it's really practical. How it works is super old news but after I understood that you have to set the slider to the minimum brightness you feel comfortable with it's been smooth, and better than setting it manually all the time I go outside.
Same here, I usually get 1 hour per 10% of battery with normal use, online, etc, unless I'm playing something battery-drain crazy like Shadowgun or Infinity Blade. I'd say 7-8 hours of heavy use is the minimum acceptable.Wow that's crazy.
That's android-like (lol)
No, but really, I can get about 10 hours of use before I have to charge it again and my brightness setting is at about 90% with most of my location services on.
