How do I free up storage on iPhone 14 Plus to back it up?
Hello - I have an iPhone 14 Plus and an iPhone 15 pro max that share the same apple id. I use the 15 pro max more and there is barely any thing on the 14 plus. I cannot back up the 14 plus as it states there is not enough storage. Please advise me what to do as I mainly want to keep the 14 plus free of apps etc. and I do not want to purchase any storage.
Thank you and I await your reply.
