TasKiller vs Adv Task Manager
Appreciated this thoughtful thread. Have used TasKiller and it was OK, but I think Adv Task Manager is better. Would definitely stay away from
Adv Task Killer, a real battery drainer, for me anyway.
I believe battery consumption/life is determined by local 3G coverage and usage.
(see earlier post by dochavoc in this thread)
In other words, if you are lucky to live in a good area coverage, the phone does not spend a lot of time "searching" for your phone with the auto programs like bluetooth, gps and wifi.
If you live in a rural setting or are in a poor reception area, manually shut down all unnecessary programs and use something like TasKiller or ATM frequently to conserve battery.
