Hi fellow Captivate users, I have wierd problem and not sure what to do with it. I read about task killers at many websites and forums. Some says its ok, some says its creates problems with performance. I mainly want to use it to save my battery. Now I have task killer Lite by Tobyyaa. It works great, but again I had doubts abt it affecting the performance of my phone. So I did a comparison between task killer and the running services in settings. In tast Killer, it shows 11 application running , including systems apps such as log provider, my uploads, and com.sec.andriod.providers.download, which starts itself. Application setting>>running application just show like 5 and doesnt show those system apps, so I cant force stop them. My main question here is, are these systems apps such as log provider, my uploads, and com.sec.andriod.providers.download, which starts itself, affects battery life and performance of phone at all? Another question is, if I leave Apps like facebook, tweetdeck open in back ground, how much will it affect my battery usage. I got this phone like 2 weeks ago and now my battery runs for more than 18 hrs...with like couple of hrs of calls, music on for most of the times, surfing for couple of hrs on Wifi.
