Hi guys, i bought a second hand Samsung Galaxy S Advance... The first phone user was female without any knowledge of update of softwares and stuffs like that... When i bought the phone it was running on Ginger Bread and i update it on official Jelly Bean firmware with kies... After update i noticed that my phone its charging faster than regular, from 20-100 % in one and half hours, it's not that bad isnt it... 
Phone battery was normal, no fast discharge, and its still normal but there is one problem... For example i use the phone and its acting normaly, i browsing, making calls, etc. when the phone comes under 50 % the battery drops percentage, for example from 46 % drops to 37 %, and after that the battery stays normal till next... I noticed after big drop of 8+ % there is 1 or more smaller 2-3% drops... I really tried everything, calibration, disharge the battery to 0% and recharge to 100%, deactivate apps but nothing worked for me... Did anyone have any idea what may be the reason for this, please let me know... Thank you
