What’s new in iOS 9.
iOS 9 brings you refinements at every level — from the apps you see on your Home screen down to the foundation of the system. Siri is smarter than ever, proactive suggestions keep you on track, and multitasking on iPad hits an all-new high with Slide Over, Split View, and Picture in Picture. All these enhancements enable your devices — and you — to do so much more every day.
Learn how to update your iOS device wirelessly or using iTunes.
iOS9 software updates introduce new features that let you do even more with your iPhone, iPad, or iPod touch. Be sure to keep your devices up to date so that you don’t miss out on the latest features.
Before you update
- Connect your device to a Wi-Fi network.
- In iOS 8 or later, tap Settings > iCloud > Backup.
In iOS 7 or earlier, tap Settings > iCloud > Storage & Backup.
- Make sure that iCloud Backup is turned on.
- Tap Back Up Now. Stay connected to your Wi-Fi network until the process completes.
- Make sure the backup finished by tapping Settings > iCloud > Storage > Manage Storage, and then select your device. The backup you just made should appear in the details with the time and backup size.
After you’ve done that your iCloud will automatically back your device up each day but only your device meets the following requirements at that specific time:
- Your device is connected to a power source.
- Your device is connected to a Wi-Fi network.
- Your device’s screen is locked.
- You have enough available space in iCloud for the backup
- Connect your iPhone or iPad to your computer and launch iTunes.
- In iTunes, right-click (or Ctrl-click) on your device, which appears in the leftmost pane under Devices.
- In the summary pane, under Manually Back Up and Restore select “Back Up Now”
- Note! If you want to save Health and Activity data from your iOS device or Apple Watch, you’ll need to encrypt your backup: Select the box called Encrypt [device] backup and make a memorable password.
- Choose Back Up.
This is a manual process and will only create a local backup when the device is connected to the computer.
Update your device wirelessly
After you finish backing up your device you can finally proceed with updating your device. The process that is the easiest and the most stress free is probably the method that requires on that you be connected to Wi-Fi.
If a message says that an update is available, tap Install Now. You can also follow these steps:
- Plug your device in to power and connect to the Internet with Wi-Fi.
- Tap Settings > General > Software Update.
- Tap Download and Install. If a message asks to temporarily remove apps because iOS needs more space for the update, tap Continue or Cancel. Later, iOS will reinstall apps that it removed. If you tap Cancel, learn what to do next
- To update now, tap Install. Or you can tap Later and choose Install Tonight or Remind Me Later. If you tap Install Tonight, just plug your iOS device in to power before you go to sleep. Overnight, your device will update automatically.
- If asked, enter your passcode.
Update your device using iTunes
If you can’t update wirelessly, or if you want to update with iTunes, follow these steps:
- Install the latest version of iTunes on your computer.
- Plug in your device to your computer.
- In iTunes, select your device.
- In the Summary pane, click Check for Update.
- Click Download and Update.
If you don’t have enough free space to update using iTunes, you’ll need to delete content manually from your device.
Now that we have covered how to update your device, lets cover a few issues that might help with any issues:

- Unplug extra USB devices.
Keep only your iOS device, keyboard, and mouse plugged in directly to your computer.
Turn off your computer and your device. Then turn them on again.
- Try again.
Update or restore your iOS device again.
