I don't use 4g at all because its not available in my area yet. I text alot and use the internet alot on my phone right now I have all my syncs set to manual or the lowest amount of syncs allowed i use a stock 1500 mah battery and it last about 10 hours for me right now. I like sense but if going to a rom that doesn't run sense make my phone more efficient ....yeah I'm all about it
