Check your camera roll, contacts, documents and settings to ensure that everything is there. If not, you can restore these from the backup you made prior to upgrading.
Finally, if everything checks out, make sure to set Auto-Lock back to the previous setting (Settings > General > Auto-Lock). iOS upgrades will sometimes turn on Bluetooth automatically. If you normally leave Bluetooth off, make sure to turn it off after upgrading. If you have iOS 7 or later, you can turn off Bluetooth by swiping up from the bottom of the screen. This will display Control Center. From here, you can turn off Bluetooth. If you are running a version of iOS prior to 7, you can turn off Bluetooth by tapping Settings > Bluetooth, and then switch Bluetooth off.
Restore If Necessary
Are you missing any personal data after upgrading? While this is highly unlikely, it is possible. If this has happened, restoring your iOS device from the backup should fix the problem. Restoring will not rollback to the previous version of iOS. It will only restore your documents, settings, camera roll and accounts.
If you used iCloud to backup your device, you must first erase the content on your device and then restore. To erase the content, tap Settings > General > Reset > Erase All Content and Settings. You will then be prompted to “Set Up as New” or “Restore from iCloud Backup”. Choose the latter option.
Restoring from iTunes is a different process. First, connect your iOS device to your computer with the USB cable. You cannot restore the device with WiFi sync. Launch iTunes and wait until your device is detected. There are two ways to restore your device. You can click the File menu, then select Devices > Restore from Back Up. If this option is grayed out, use the alternative method. Click on the “Devices” button on the top right of the main iTunes window, then click on the device you would like to restore.
The Summary screen appears. Click on the “Restore Backup” button and follow the instructions. Your device will be restored.
Some users reported issues with grayed out WiFi after upgrading. Other users experience Bluetooth problems. Reports of battery life issues after upgrading are common. It’s a good idea to re-calibrate your iPhone, iPad, or iPod Touch battery after an iOS upgrade. First, use your iOS device until the battery runs out. Leave it off for a few hours, then charge it all the way to 100%. This will reset the battery meter. The upgrade doesn’t decrease battery life. Your device just needs to have the battery meter re-calibrated.
Upgrading iOS is a simple process. Most users are able to do this without experiencing any problems. Following these best practices will make for a smooth upgrade process. I have yet to experience any problems with an iOS upgrade. Even if you have never faced a problem, it’s still a good idea to follow these steps to ensure that your personal data is not lost. It’s also a good idea to backup your device regularly.
