4.3 is destroying my battery, i want to downgrade to a past version, specifically 4.2.1 but for some reason the only one showing up in my saved shsh is 4.1. how is 4.1 i cant even remember? did it have any problems that 4.2 fixed? I cant loosed 40 percent of my battery in a half hour doing nothing but light texting, but i also dont want to downgrade to 4.1 if it will cause compatibility problems with my apps or something. any thoughts or help would be greatly appreciated
