Not enough space for downloading iOS 9

iOS 9 officially requires just 1.3GB of free hard disk space for installation, while several iPhone and iPad users with 8 and 16GB models may face storage constraints, especially if they do not employ manual syncing methods via iTunes. If you are among the affected users then try to temporarily delete the apps to regain some precious storage space and then complete the iOS 9 update.

Other notable solutions include removing messages and attachments from e-mails, clearing junk files on your device with PhoneClean, and also transferring your personal data such as photos and videos to computer from your device.

Cellular data not working

Some iPhone users are reportedly complaining about cellular data issues, despite facing no hassles with Wi-Fi connectivity. Affected users may try out a few potential fixes to resolve this problem.

  • Restart your iPhone: shut it down and reboot it.
  • Turn Cellular Data off and then back on again by navigating to Settings > Cellular and select Toggle Off > Toggle On again.
  • Try toggling Airplane Mode on for about 30 seconds: Open Control Center > Tap on the Airplane icon > After 30 seconds, turn it off again.
  • Reset your iPhone: Go to Settings > General > Reset > Reset All Settings. No user data is lost while doing this task.

Bluetooth problems

Some isolated instances of Bluetooth connectivity problems have been reported in iOS 9, wherein users are unable to connect the iPhone to the in-car Bluetooth systems or Bluetooth suddenly disconnects during an incoming call or the connection drops abruptly.

Here is what you should do to overcome these problems:

  • Turn off Bluetooth and restart your iPhone or iPad.
  • Repair the Device you Connect: Go to Settings > Bluetooth > Choose the device you are having issues with > Tap on the info button next to the device > Tap on Forget This Device.
  • Reset Network Settings: Settings > General > Reset > Reset Network Settings. Just set up your Wi-Fi connections once again after doing this.
  • Try restoring your iPhone iPad: You can restore your device from iTunes or iCloud. Note: This will erase your existing user data so you should back up your iPhone or iPad in advance.

Low battery-life problems in iOS 9

Despite featuring the new Low Power Mode, iOS 9 seems to drain your device's battery life quicker than expected as reported by some users. Here are some nifty tricks to extend the battery life on your iPhone/iPad running iOS 9:

  • Go to Settings > General > Usage > Battery Usage to see if any app is draining the battery too fast. You may try deleting the offending app or replace it with an alternative.
  • Streaming music via Apple Music is known to drain battery life. So, you can try downloading songs onto your device's local storage instead of streaming them online.
  • Enable Airplane mode if you are receiving poor signals. This will prevent your phone from continually switching between connections in dead signal zones and thereby protect your device from the negative impact on battery life.
  • Try restarting your phone or Reset All Settings: Open Settings > General > Reset > Reset All Settings and then enter your pass code.

iMessages failing to send in iOS 9

Some users have reported that the iMessage app is failing to send messages or taking too long to complete the task. Such issues can easily be resolved using a few simple steps as outlined below:

  • Check Network Settings/Wi-Fi: As iMessage works on the 3G or Wi-Fi network, it is better to make sure that you are closer to the source/router. If using 3G network, try restarting the cellular connections.
  • Turn Off and then Turn On iMessages Again: Settings > Messages > Turn Off iMessage and turn on it again.
  • Verify you send the message to an iMessage-user.
  • Sign out of Apple ID (go to Send & Receive) and then re-sign in again. Repeat the turn Off-On step as explained earlier.
  • Try resetting your iPhone: Go to Settings > General > Reset > Reset All Settings.

Failed to activate iMessage and FaceTime after iOS 9 update

Some users are reporting on the Macrumours forum about the inability to activate iMessage and FaceTime features after the iOS 9 update:

"I previously had the iOS 9.1 beta on my phone, but reverted back to the public release of iOS 9. Since downgrading today I've had this problem. I checked Apple's status page and all services appear to be functioning properly and Google searches have come up dry, leading me to believe that this is a problem on my end."

If you are among the affected users, ensure that your device is connected via cellular data or Wi-Fi network. Also verify that the SMS messaging service is enabled on your iPhone before trying to activate iMessage or FaceTime. You may be charged based on your carrier plan for using the SMS service.

Proceed with the troubleshooting steps as outlined below:

  • Go to Settings > General > Date & Time and make sure that you've set up your time zone correctly.
  • Turn off iMessage and FaceTime and restart your iPhone iPad: Go to Settings > Messages and turn off iMessage (Go to Settings > FaceTime and turn off FaceTime) > Restart your device > Turn iMessage and FaceTime back on.
