Okay, so I officially want to know from real life experience, have any of you noticed an improvement in battery life by utilizing the program Advanced Task Killer (ATK). Yes or No. I've heard arguments for and against using ATK which people have claimed could save battery life by killing off background aps and processes that hinder battery life by using the CPU in the background. Some people say it works, others say "dude you are an idiot, you must not know anything about Android or linux, Aps don't run in the background with Android, its the beauty of Android" or something to that effect. Maybe I'm an Idiot, but here is my experience. I have used my phone for periods of time, with and without ATK. I can deffinately say from my own real life experience, that running ATK improves my battery life. Maybe its a mental placebo effect I dont know. For those who say it doesn't work, I just have one common sense question, so here it goes. If Android is so smart, and it doesn't run background aps on it's own, which would use up energy, then why the heck does AmazonMP3 load up by it's self every 2 mins in the background. I never even use the stupid program, so common sense says if Android doesn't run background Aps like AmazonMP3, then how does it mysteriously show up on the list as being used in the background? Also I've read on xda people who root their phone, and manually remove programs like this, and they saw an improvement in battery life, isn't that more proof that indeed these programs use some energy in the background, thus ATK does help?
