How do I know which applications slows down the phone, so that I could get rid of them?

Although you can't find out what apps are 'slowing down' your phone, you can find out which apps are using your battery the most. Generally if apps are using a lot of battery power, they're probably slowing down your phone too.

You can find the list of apps vs battery usage in Settings > Battery.

    My battery use is 57% screen, 25% voice calls 13% camera... If this is the only solution, I might as well throw the phone away. :'(

The Watchdog Task Manager app is really great for these kinds of problems.


There is yet another aspect, Constantly running background (daemon) services that are usually associated with network updates, mails, facebook, sugarsync, dropbox etc.. can get the juice out of your phone very quickly, you need to keep track of such 'zombie' apps that keep these background services running. Look at them once and make sure you keep what you need. Be careful it can have lot of side effects.

Settings -> applications -> manage applications -> running (tab)

Hope it helps you.


Hmm.....Try "advance task killer" which force stop all apps except for selected. or manually by going to application select force stop on each application.
