SGS2 has its own task killer, and there is a popular android app killer. However, sometimes I noticed that there is a difference in the apps which are opened at the time. Sometimes the built-in app killer does not show anything on, but in the android app killer, it lists lots of apps working in the background. I end up killing them like every hour. Then I read this from lifehacker:
Android Task Killers Explained: What They Do and Why You Shouldn't Use Them

Now I'm not too sure. I'm using the phone for the second day, and I can say that there is no more battery (turned the phone off at 1% left). The battery did not last a day. I was using the phone while it was charging for some time, and it did got hot. Looks like this is a bad thing to do and I got a warning from the samsung in-built not to do it. I did not charge the phone full before I started using/getting to terms with android. 2 hours+ on games, about 5 hours on wifi, 30 mins on compass, played with unifi remote, gps not turned on-which I think qualify for heavy usage.

I also changed the power saver settings, but I cannot see any difference. Wifi is still on, screen brightness was not 10%, it looks the same, though not sure if that is the SA+ screen's capability.

I am also using lookout, which seems like its running in the background forever. Its quite a useful app, though if I am not mistaken Samsung has something like SNS or something which replicates the locate my phone app but does not come with the antivirus.

I've uninstalled the android app killer and stick to the in-built app killer. Is this a sensible move?
