zMax pro (metro pcs) wifi keeps turning on

[mckinley]

i have a zmax pro on metro pcs and over the past 2-3 days the wifi keeps turning itself on. I thought it was an app that i downloaded so i deleted/uninstalled it thinking that would solve the problem - it hasnt i researched this online and know about connection optimizer but i cant find it on my phone. It is annoying and like others who had this problem my battery which use to last almost 2o hrs now last 12 - 15 hours. this happens even when there is no wifi signal to connect to, please help.
