To fix slow iPhone 4, the first thing is to cut down apps with big sizes. You can check the storage occupied by every app in Settings> General> Usage> Manage Storage

Tip 2. Close Running Apps Frequently

When you close an app, the app is not really closed, but still active in case you need to use it later. It’s not hard to imagine that several such running background apps will take up a lot of RAM resource; after all, almost all apps are over a hundred MB in size. You can close undesirable running apps frequently to fix iPhone 4 running slow. Double click Home button and you will see a list of running apps you have opened. Pressing on the window above the app icon and sliding it up will close the app.
