I have two questions: 1.) Google Android developers have said that task killing is not needed due to the way the Android OS handles processes. Am I the only one, or does killing apps significantly increase the overall speed of the phone? For example, if I have 23mb of memory left, scrolling between home screens is very sluggish. If I kill all of my apps and have 50mb-70mb of free memory, scrolling is noticeably faster. What does google mean when they say that task killing apps are not necessary? 2.) Why does free memory decrease the longer your phone is on? For example, I set the following apps to "ignore" on taskiller: -MMS -E-mail -Gmail -Home++ -WeatherChannel -Scoreboard When I reboot my phone and kill all apps, I have 94mb free. However, after 2-3 days of my phone being on, when I kill all apps, I have close to 52-54mb of free space. Even if I kill every single app that is running (including my ignored apps), I never get close to 94mb free. What runs in the background that is taking up that extra space?
