...ATK helps the phone's battery life by killing all the unnecessary bloatware that loads up automatically.
Absolutely incorrect.
I've watched my Battery History (in Spare Parts or the Testing Menu -- *#*#4636#*#*) closely, and NONE of the "bloatware" items have ever even registered. They aren't responsible for ANY battery drain if you do not use them (which I don't). If they are loaded into RAM but not using CPU cycles then they are not using any battery power. Even now, my phone has been on for 53 hours, and even though Skype, Amazon MP3, CityID, Stocks, FM Radio, FriendStream, Footprints, Peep, VisualVM, Backup Assistant, and VZ Navigator are all loaded ("running"), none of them has used any battery since last reboot. Not one of those apps appears under CPU usage, Network usage, GPS usage, sensor usage, partial wake usage, or other.
If you read up on what it means for an app to be "running" on Android (the very good Lifehacker article linked on this forum yesterday is a great source), you will understand that an app -- or 1000 apps -- can be "loaded" into RAM but not actually ever do anything. They are dormant. They are in RAM simply so that they can be launched quickly if the user visits them. It seems that part of Verizon's devil's bargain with HTC was that its bloatware items should be treated preferentially by the system and kept in RAM, so that users would experience rapid load up if they chose to use them; and likely this was to manage perceptions (i.e., so that users wouldn't complain that this software they didn't ask for ALSO runs really slowly).
Bottom line: if carrier bloatware, and not crapware that you loaded yourself, is you concern vis-a-vis battery life, then you 1) need not be concerned and 2) you are barking up the wrong tree for a solution with ATK.
