It is my belief that people who express serious issues with using a task killer have no clue how to use one properly. Task killers are only for stand alone apps you don't wish to run at any time in the background unless and until you intend to use it. That said, the ignore list needs to consist mainly of actual factory set android phone functions and the few apps you wish to keep running bc you use them alot, or have some sort of notification alert set to them. (ie email, twitter, facebook etc..) I've heard all too often "the Task Killer suddenly rebooted my phone." Why? oh is it perhaps you have the factory set "makes the phone freakin' work" Sense UI in the "Kill" list? "My alarm won't work since i've installed a task killer, now i've lost my job bc of oversleeping!" why? bc the clock is in the kill list? "the damn weather widget wont update!" why? bc you have the weather in kill list! You see where i'm going with this right? ok, moving right along.. Understand that apps are NOT always idiot proof! Don't assume that you can install it and hit "auto kill" thinking the thing works fresh from the market-psychically tuning in to your mind to determine what apps you want to keep or kill. what things you phone needs to keep to work properly or kill etc.. if this were a walgreens commercial that would be an occurrence in the land of perfect..but this isn't Neverland so a bit of research and caution is needed in order to make the app of your chose function in the way you need or want. For task killers there is a bit of effort needed from you to not only adjust it to kill what you want killed, but also to protect the phone it's self from mass restarts and possible loss of much needed setting functions. my rule of thumb? if it has anything in it that appears to be something from your android system that isn't an app name but what looks like code then KEEP IT! especially if it has HTC. in it. JUST READ IT! stand alone apps are clear cut with a clear name..those are kill discretionary..i keep my twitcaster, gmail, facebook, handcent, weather, & clock on the ignore list..why? bc these apps either have no problem "back" tracking out of to close, or i want my alerts to work properly..besides, to my way of thinking it seems more taxing on the phone's battery to have to "restart" these items everytime you open them than it is to just quietly keep them running with little to no battery drain as a result. let the phone do it's "thang" and continue to multitask. as far as battery life? c'mon people it's a multitasking, net surfing powerhouse of a phone! You can't seriously expect to use the blasted thing the way it was meant to be used and demand and all day full battery reading..be rational here folks, if you allow the phone to do it's natural stuff in concert with proper task killer use, then you should get pretty decent & or realistic play time with your phone. (extent of usage permitting) Take the time to read the many battery saving tips found on the internets and research ALL the apps before you install anything on your phone..educate your self and your phone works for you. savvy?
of course that's just my opinion, i could be wrong.
