The song, video, or other item does not play.
Perhaps the song is encoded in a format that the iPhone does not support. iPhone supports audio files of the following formats: .aac (m4a, m4b, m4p up to 320 Kbps), Apple Lossless (high quality compressed format), .mp3 (up to 320 Kbps), .mp3 Variable Bit Rate (VBR), .wav , .aa (audible.com speech, formats 2, 3 and 4), .aax (audible.com speech, AudibleEnhanced format), .aiff. This list includes formats for audio books and podcasts.
iPhone supports the following video file formats: H.264 (Baseline Profile Level 3.0), MPEG-4 (Simple Profile).
The song, encoded in Apple Lossless format, has CD sound quality, but takes only half the space compared to a song in .aiff or .wav format. The same song in the .aac or .mp3 format takes up even less space. When you import music from a CD using iTunes, the default content is converted to .aac format.
Using iTunes for Windows, you can convert unprotected .wma files to .aac or .mp3 format. This function is of interest if there is data in the media library that is encoded in the .wma format.
iPhone does not support .wma, MPEG Layer 1, MPEG Layer 2 audio files and the audible.com 1 format.
If there are songs or videos in the iTunes library that are not supported by the iPhone, you can convert them to an iPhone-supported format. For more information, see iTunes Help.
Backups can be created in the following ways:
- After the iPhone is set up to sync with a specific computer, iTunes automatically creates a backup of the iPhone on that computer when it syncs. iTunes does not automatically back up an iPhone that is not configured to sync with this computer. If you set up your iPhone to automatically sync with iTunes on a specific computer, iTunes will back up your iPhone every time it is connected to your computer. Automatic synchronization is on by default. iTunes creates only one backup each time you connect a device, even if it’s been synced several times before it was disconnected.
- If you decide to update the software on your iPhone, iTunes will automatically back up your iPhone, even if it is not configured to sync with iTunes on this computer.
- If you decide to restore the iPhone software, iTunes will prompt you to back up the iPhone before restoring. If you are using a Bluetooth headset or car kit from an iPhone and you are restoring a setting, you must reconfigure it to work with an iPhone to use a Bluetooth device.
Restore from backup
You can restore settings, downloaded programs, and other information from a backup, or use this feature to transfer these items to another iPhone device. For this:
- Connect your iPhone to the computer with which you usually sync.
- In the iTunes sidebar, select iPhone and select the Browse tab.
- Select “Restore” to reinstall the iPhone software, restore the default settings and delete the data stored on the iPhone. In iTunes, you can also restore from backup without deleting data stored on your iPhone.
Deleted data becomes unavailable through the iPhone user interface, but it is not permanently erased from the iPhone until it is replaced with new data. When prompted, select the option to restore the settings, downloaded programs, and other information from the backup, and select the backup you want to use. Several backups are listed separately for each device in chronological order, the most recent backups are listed first.
You can delete an iPhone backup from the list of backups in iTunes. This may be necessary, for example, if a backup was created on another user's computer. For this:
- In iTunes, open iTunes preferences. For Windows, select: Edit / Preferences. For Mac, select iTunes / Preferences.
- Select “Devices” (iPhone connection is not required).
- Select the backup you want to delete, and click Delete Backup.
- Confirm the deletion of the selected backup by clicking "Delete Backup".
- Click OK to close the iTunes settings window.
Update and restore iPhone software
You can use iTunes to update or reinstall iPhone software, restore default settings, and delete all iPhone data. If the iPhone is updated, your software is updated, but the downloaded programs, settings, and songs are not affected. When restoring, the newest version of the iPhone software is restored, the default settings are restored and the data stored on the iPhone is deleted, including downloaded programs, songs, videos, contacts, photos, calendar information and all other data. In iTunes, you can also restore from backup without deleting data stored on your iPhone. Deleted data becomes unavailable through the iPhone user interface, but it is not permanently erased from the iPhone until it is replaced with new data.
