Hey guys, I'm sure a lot of you already know that tip but I'll say it anyways because the increased battery life I got from this tip is crazy

I now have twice as much battery using this option


If you don't use 3G:
Go to settings
Phone
Network mode
and set it from dual to GSM

As I said before I'm sure people are aware of this tip but I made this post to highlight the benefit of increased battery life
