It started happening about a week ago, my phone has been disconnecting and connecting from the charger cable and not fully charging to 100% even if it was plugged in all day, more than 24 hours. I have been trying to figure out whether it is the charge port or the battery or the phone itself that is giving me trouble. It is definitely not the charger cable, as I have 3 different ones and they are all perfectly fine. I have removed the battery, re-inserted it and everything and restarted the phone several times. The phone itself runs very slow. The battery drains insanely quick even when I turn the phone off or shut down every application+data+wifi and everything in the background. I could not figure out whether my battery was water damaged either, the sticker on the bottom is bright red(no X's, just pure red), and yes I found a red leak once on the back of my phone, however I have never dropped it in water before(maybe snow?), but I always wipe it off real quick if I drop it. I have had this phone a little more than a year(bought it last July). If anyone has any ideas, or can verify whether it really is the battery or not, please let me know. Thanks!
