STOP USING YOUR PHONE SO MUCH!!!! J/K For those of you having to charge battery every 4-5 hours, I have the solution. I take no credit for this as I saw it on another forum. Go to settings>wireless&networks>mobile networks>Enable always-on data. Uncheck always on data. Your phone will still receive email,text,& phone calls as before as well as internet usage but your battery will last a lot longer. Currently at 37% after 9 hours of use compared to being completely dead after 4 hours.
