So this is the first phone that I've rooted and I have enjoyed the benefits of custom roms. Carbon is the one that I've stuck with for a while now. Running custom roms can provide extra functionality such as overclocking/underclocking the CPU, full screen mode, and tethering without paying the carrier more money. If you're on T-Mobile then unlimited data to run two or more devices is great. Of course there are other reasons like being able to change the screen's color settings as well. As far as better battery life, I'm always on my phone so I can't say that my battery life is good at all. Idk. Maybe I'm just not doing it right but I am enjoying the phone more now than with just stock android. Anyways YouTube it, research it and if you mess up, someone's always here to help you correct your mistakes.
