AppleAAPL +2.07% iOS 10.3 is here with some confusion from users who have already upgraded – it’s important to tell you about one important part of the update which is giving users a nasty surprise…
The good news is there is a reason why you’ll be giving up a sizeable chunk of your time while iOS 10.3 installs on your iPhone, iPad or iPod touch: it introduces an entirely new file system.
Simply called ‘Apple File System’ (APFS), it replaces the ageing HFS+ (launched in 1998 and based on HFS launched in 1985!) and will roll out across macOS, watchOS and tvOS as well. Aside from under the hood benefits like SSD optimisation, improved backups and cross platform full disk and individual file encryption, end users will also find APFS can free up storage space.
Notably, Forbes’ own Brad Moon found iOS 10.3 freed nearly 2GB on his 32GB iPhone 7. Apple has a detailed PDF on APFS for those looking for (very) detailed information.
As such, while iOS 10.3 may appear to lock up your device on upgrade and have you reaching for the panic button, the reality is if you wait this one out your patience will be rewarded.
