Hi, for me tbh, battery life is good. I am using this for internet, emails, calls, whatsapp, bbm and other social hub thing. no slow down at all but I cannot say much for games as I never tried playing on it. but looks specially the color gold, which I am using now is really very good. it is super slim, no random heating. be sure to check the baseband version is C5000ZHU1APG1, this is the most stable os for this mobile as of now.
finger scanner is a tad slow and sometimes failed to recognize my print. earpiece is not that clear, sound is not that crispy, sometimes it is hard to understand what the caller is saying. ambient light sensor has this delay. if you are into calls, I suggest to you to avoid this one.
