Also another thing that happens when I'm charging with the battery pack on my pocket that my phone heats up which is not good. My battery pack contains 5200mAh or maybe I should charge it outside my pocket so it doesn't try to heat just to conserve battery so fast. I just wanted to keep this phone or maybe I should look into other options of other phones like the Samsung Galaxy S4, Nokia Lumia, or a Samsung Galaxy Nexus even a iPhone 4/4S. Android or Windows Phone may be a good choice since I have accounts associated for those operating systems or maybe I should buy another battery pack with less capacity just to avoid it from overheating..
I get around a good 6-10 hours of battery life on a day I use it the most, 6-20 if I'm not using it. Somehow I'm hoping that a update will come just to change this kind of atmosphere of this battery draining crap.
