why is my battery draining so fast

[AC Question]

I have disabled all the crap from the "update" that isnt even compatible with my device. Ive cleared my cache. I have uninstalled all the Apps from 3rdparties. i literally have a factory phone yet this morning i disconnected from my charger and walked down the hall and got ready to make a call and my phone had died. i plugged it back into the charger and it was literally on 3%

What phone brand and model is it? How old is your phone, and did you buy it new or used?
