Downgrade iOS for better battery life?
The reason I raise this question is a good friend of mine that I also work with has a 3GS that he has never done an upgrade on and he gets awesome battery life he watches YouTube videos and surfs all day and bye end of the day (12hr shift) he still has 50% battery.
Meanwhile I am running 5.1.1 and my battery life sucks and I even do things to help like turn off 3G, low brightness, and don't do to much just surf a bit and visit tapatalk. I do steam music on my way to work via an aux cord it's about a half hour ride. By the time I get to work I'm usually at 90% already. I don't leave home without my charger and if I do I can't really use my phone all day cause it won't make it. Is the 3GS not meant to run on ios 5 or am I just screwed? What os do you guys run on the 3GS?
