If you get a notification saying your device needs more space or memory, act on it right away! Without sufficient storage, the next time your device needs to make a crucial security update, it may not be able to.
True story: one of our reviewers once bought a computer with a smaller memory than her phone. She used online storage for all her computer photos, documents, and games to create more space. Even with that precaution, the routine updates quickly outpaced the available hard storage. That reviewer replaced the computer much earlier than planned because with no storage and no updates, it was near useless.
Don’t let that happen to you! If you can’t clear space on a device by deleting content, we suggest cloud storage (like an inexpensive monthly iCloud subscription) or extra hard drives if possible.
And if those solutions don’t work, then just like our reviewer, you’ll probably have to update.
