If your iPhone is moving at a slow speed, and in case you wish to figure out how to fix the problem, then read on to follow the simple steps mentioned below:
Kill Recent Applications in Your Fast App Switcher
A rouge process could be eating into the memory of your device. The iOS 4’s new fast app switcher interface lets users get rid of both their third party App Store and Apple apps, which may be creating problems in the background. In order to access the fast app switcher in iOS 4, you will have to double click the home button on your iPhone. Following this, the interface will slide up and then reveal a second dock-like set of application icons (in the background). Now to kill an application, you need to tap and then hold the application until the icons begin to jiggle. After this, you need to tap the minus symbol (-) at the top left corner of the screen. This will lead to the application’s removal from the background dock (however, not from your iPhone). This forced kill or quit action will do a number of different things, based on the type of app.
To begin with, (in case of built-in Apple applications) if you get rid of them from the fast app switcher, they will continue to run in the background. Hence, if you kill mail, you will still continue to receive mail (it doesn’t get rid of the background threads). However, it will instead force the background thread to start all over again. Therefore, if something is not working properly with your Mail, for example messages aren’t visible properly, this could be a great way to clean and start from the beginning. Similarly, it can force Safari to reload pages without rebooting your device.
In case of applications that you may have downloaded from App Store, if you end up killing them from the fast app switcher they won’t continue to function in the background. You will continue to get push notifications as they are handled by an external server. However, you will lose things like navigation, background music playing, VoIP, and saved state. Therefore, when you launch the application the next time, it won’t begin from where you left it but will be re-launched right from the beginning. Now, if an app is misbehaving or giving you some sorts of problem, by killing it you can force a refresh without resorting to rebooting your iPhone.
Restart your device (hard or soft reset)
You can restart your iPhone, in case it is working slowly. For this, you need to hold down the Wake/Sleep button till a red slider appears on the screen. You need to slide your finger across the slide and your iPhone will turn off on its own. Now, turn your iPhone back on again by simply pressing the same Wake/Sleep button until the Apple logo appears on the screen. However, if you continue to face the problem even after turning the power down or in case the power down option fails due to a freeze up, you can rely on another option. For this, you will have to reset your device (this won’t result in the loss of data) and then re-install or delete any apps that could be posing problems.
In order to delete apps on your iPhone, you need to touch and hold your finger down on the application until it goes into the “Jiggly Mode” (begins to dance around). Now look for the small X badge which is located on the top left of the application you wish to delete. Following this, you need to tap the small X badge and a dialog box will pop up that will identify the name of the application you’re about to delete. This will warn you that you will end up deleting all the data in the app as well (which could be your account login and game in progress, etc.). Now, if you are sure, tap Delete, and if not then tap Cancel.
In case you have decided not to get rid (delete) of an application, you can tap the Home Button to exit Jiggly Mode. On the other hand, if you have selected the Delete option, remember, you will have deleted the app. Now, if you wish to delete more applications, just tap their X badges in a similar manner. In case you are jailbroken and have a ton of tweaks running, try to remove them and then re-add them one at a time and just check if it helps in indentifying problems.
Update your iPhone and install the latest firmware
For this, you will have to first connect your iPhone to your PC using the USB dock cable. The moment iTunes opens, your device will show up with a little icon in the left sidebar. You need to click on it and then sync your iPhone you have not done that in a while. iTunes will then create a backup so that it can restore it after the update (you want this to be as recent as possible). Now, in the main window, you will have to click “check for update” option.
In case a software update is available, a box indicating the same will pop up. The download will start on its own and once it is done, iTunes will prompt you to install it. The installation process will take some time and then your iPhone will reboot on its own.
The moment the update is over, iTunes will again prompt you to restore from a previous back up or set the download up as a new device. It is always better to restore from backup, you will save yourself lots of work entering all your applications and info again. Your device will again restart once the restore is finished. You can then sync it with iTunes in order to get all your media and apps loaded back on. After doing this, you will have updated your iPhone.
Restore Your Device as New
This should be the last resort because once you follow this you will have to reinstall everything on your iPhone once you have done this. Therefore, to restore whether on a PC or Mac:
- Plug your iPhone into your PC.
- In case iTunes does not launch automatically, go right ahead and launch it.
- On your left, you will see a sidebar, click on your device.
- Now you will see a restore option.
- You must ensure that you backup your phone first. You can do this by syncing it or right click on your device name in the sidebar and then select backup.
- Now, simply click on this and allow iTunes to do its work for a few minutes.
Once the restore is finished, you will either be asked to set up as a new iPhone or restore from a backup. In case you choose to restore from a backup and your iPhone still does not work properly (i.e. the problem returns with the backup), it would be good to restore again and this time try and set up as a new device. Now, re-sync your content and you should be fine.
