Step 1: Check
Unlike previous releases iOS 9 runs on most current iOS devices, though not all features work on all of these. What it means is iOS 9 runs iPhones starting from 4S up to 6 Plus; or iPads from iPad 2 on (including iPad Air and iPad mini). This support implies current models will all hold value well once new models ship.
Step 2: Market
Price comparison site Flipsy.com tells me iPhone market values drop between 15-40 percent in the weeks before a new iPhone launch. To get the best price you can on your existing iPhone you have two choices, sell it early and make do with your mum’s old Nokia, or search out a ‘price lock’ deal that agrees a price now which is then frozen so you sell when new models ship (or try T-Mobile). Flipsy.com is one place where you can check current second user iPhone prices and search for buyers offering price locks. Now you have a picture of what your phone is worth and may have agreed a sale price so you can quickly upgrade when the new iPhone ships.
Step 3: Edit
Upgrade time is a good time to review your stuff. Do you still use all those apps Watch all those movies Have you archived and sorted through your images No Digital lives create so much data it’s good practice to delete or archive things from time-to-time. Take a look at Settings > General > Usage > Show All Apps to vet what apps you have and the space they consume.
Step 4: Home
Now you’ve deleted some apps you might need to manage your Home screen. Put the apps you use most on the front page, while putting groups of apps in folders elsewhere.
Step 5: Traces
Unlink your device from Apple Pay, Find My iPhone and iCloud services before you sell it. To delete everything on your device use Settings>General>Reset and choose then ‘Erase All Content and Settings’. If you have Find My iPhone enabled you’ll be asked for your Apple ID.
Step 6: Backup
I hope you backup your regularly, but you should certainly do so before sale of upgrade. You can backup through iTunes on your computer or via iCloud (subject to paying for sufficient space). While iCloud will backup automatically, iTunes needs you to run a manual sync. The big iCloud advantage is it lets you restore your device backup online from anywhere, not just your Mac.
Enable iCloud backup:
Settings>iCloud>Storage & Backup. Enable iCloud Backup. To restore from iCloud go to Settings>General>Reset All Settings and choose Restore from iCloud Backup from the options you find.
Enable iTunes backup:
Launch iTunes and select your device.
First time you’ll be asked to select what content you wish to backup. To restore a device, connect the device and choose ‘Restore from Backup’.
To protect my library I like to offload photos and video to additional storage media, such as the reliable SanDisk Connect series of iOS-friendly drives.
Step 7: Account
Please ensure you know all your iCloud account details (email, passwords) and your device passcode as you’ll be asked for these when you upgrade iOS or setup your new iDevice. Users of more advanced services (such as VPNs) may also need to note any relevant passwords/information for these before they upgrade.
Step 8: Patience
Every year millions attempt to install the new OS the moment it becomes available, and downloads are slow. Be patient, wait a day, and you’ll have a better upgrade experience.
Step 9: Verify
When you upgrade iOS or set up a new iPhone, it sometimes makes sense to check through Location and Notifications settings to ensure no apps have cheekily given themselves permissions to use these services if you didn’t want them to.
