Apple released iOS 8.3 on April 8th 2015, and I guess many people have tried the updating though it is not as expected as bug-free, since there are many complains and asking-for-help posts, such as Touch ID issues, battery problems, Wi-Fi connectivity problems, Bluetooth problems, App issues, etc. Therefore, we update our post for iOS 8.3 trouble shooting so that you can upgrade to the most current iOS 8.3 operating system smoothly.
Problem 1: Insufficient Free Space for iOS 8.3 updating
The iOS 8.3 update requires storage space as large as 5GB space, depending on your device model. So the first thing you need to make sure is to check how much storage left, go to Settings > General > Software Update. If your iPhone, iPad, and iPod Touch don’t have enough space for this IOS updating, it means you need to delete a massive chunk of photos, videos, music and apps to make room.
Delete Photos and Videos
Photos and videos are usually two items that take too much space. Don't trust iCloud to have all of your photos backed up. To safeguard your photos, the safest method is to transfer photos to computer first, and then delete photos from your iPhone. To do so, you need some third party data extracting software, like iFonebox, to extract all the photos and transfer to your computer for a physical backup.
Delete Apps and Games
Focus on those apps and games that occupy too much space, or that you don't use that much, even ones that can be easily replaced once the iOS 8.3 update is finished. Avoid deleting apps that may contain your personal data or projects.
Notes: Before deleting them, you'd better transfer apps & games with process and data first.
Problem 2: Data Loss after Updating to iOS 8.3
Data loss happens after iOS 8.3 updating, due to the following reasons. For enough updating space, many users choose to delete their device data, such as, photos, videos, messages, contacts etc. Update failed. Problems appeared in the process of upgrading, resulting in loss of iOS data. Go to recovery mode. All the data on the device is erased, and the device goes to the Recovery Mode.
If you have backed up your device via iTunes or iCloud, you can simply restore it from iTunes or iCloud. Note: As every Apple users knows clearly that neither iTunes nor iCloud supports selectively data restore, and restoring your device from iTunes or iCloud will cause the erase of existed contents on your device.
Problem 3: Stuck on Apple Logo
This is one of the most severe problem affecting users after iOS 8.3 upgrade. Solution: To fix this problem of iOS 8.3 device stuck on Apple logo, you can hold down the Sleep button to turn off your device; convert your iOS device to your computer to start iTunes; hold down the Sleep and the Home button for 10 seconds; release the Sleep button and keep holding the Home button till a message appears in iTunes; and select your device and click Restore option under Summary.
Problem 4: iOS 8.3 users see issues with battery drain.
To ensure you can extend the battery life, it's important to optimize the settings on your iPhone, iPad or iPod touch. Find apps consuming battery by going to Settings > Usage > Battery Usage; Turn off cellular data by going to Settings > Mobile and pressing the Mobile Data switch; press the power and home button until the device turns off to conduct a soft reset; turn down screen brightness; and turn off Bluetooth and airdrop.
Problem5: iOS 8.3 Update Stuck
This can happen at both times: when you try to do an OTA update or when you try updating through iTunes. There can be a lot of reasons but predominantly, this could be some software glitch or a server issue.
Irrespective of when this happens, you can always restart the update process by turning off your iPhone and then switching it back on. If the iPhone / iPad doesn’t respond (or it gets stuck in a boot loop after you turn it off), connect it to iTunes. Mostly, iTunes detects the iPhone in recovery mode. Yes, you will lose data if you didn’t remember to backup first. But you can restore through iTunes. If you were updating through iTunes and it gets stuck, do this: force quit iTunes, disconnect the iPhone from the computer, open iTunes, reconnect the iPhone and restart the update.
