Hi after months of using this phone i really love it but one thing is killing me, the slow charging feature!!!!! I would get through the day with it but if i want to go out at night it would most likely die on me since i cant leave it charging for long before i go out. Now i'm considering going to the s4 and purchasing extra battery packs so i can change whenever I need the additional power. I just wanted to know if the S4 still had the lag issues that everyone was complaining about. Did they ever end up fixing it?
