hello everyone im new here. i bought a black mist galaxy s4 directly from t mobile and i also ordered a black obliq xtreme pro case from amazon [hopefully both show up tuesday] i was doing some reading on the tempered glass and decided i liked the spigen glas.tr and ill be purchasing the raised home button from them too. now on to my questions, i would like to get a bigger mah battery for my s4 but im not sure how big i can go with the xtreme pro case,any ideas? is the spigen glas.tr the best that spigen offers or is there something else that trumps it? any other advice you can give me about the s4? thank you for your time everyone
