This is kind of a detailed question, but basically, I have been reading through some threads and came across someone who wrote that keeping the wifi turned on to 'never sleep' optimizes your battery life by a lot (instead of using mobile connection). So I set this up, but I also have the app Advanced Task Killer and I am trying to figure out if I need to set the wifi to the ignore list (so that it doesn't get killed everytime) or if Advanced Task Killer doesn't effect this. I am just trying to optimize my battery so I can actually use the internet without it dying on me so quickly. I charged it all night and literally 5 minutes after I unplugged it, my phone was down to 90% life. Seriously?
