    I have an older iPhone 5 that I keep for backup. I currently have a iPhone 7 plus. My iPhone 5 is 16Gb, iPhone 7 plus is 128Gb.

    Now I obviously have a lot of apps on my iPhone 7, larger Gb.

    What I'd like is if going on holiday to take the iPhone 5, not have many apps etc on to use and hopefully keep my messages emails etc in sync.

    So is it possible for me to do an iCloud backup on my iP7+, then connect the iP5, restore from backup but stop the apps installing and use that.

    Then the reverse when back off holiday, iCloud backup on iP5, then restore to iP7+ and all messages etc will be there?

    Does anyone do this? Problems, tips etc please. I'd like to keep everything in sync but don't want to take the iP7+ away and just use the older backup iP5.

    Thanks

    Why go to all the hastle?

    Set the phone up as new or restore from backup that's your choice but there's no need to mess round when you get back. The messages will be on both devices providing you don't mess around with the iMessage settings.

    Whatever you do, just be sure that BOTH phones are on the same version of iOS.

    You cannot restore a device from backup if that backup is from a version of iOS that is newer than what the current device is using.

    I.e., if hypothetically, your iPhone 5 is using iOS 9.3.5, you cannot restore from your iPhone 7/iOS 10 backup. You'd need to upgrade the iPhone 5 to iOS 10 first.

    are you sure? It's not hassle I just want everything in sync. Don't want to lose my messages so when I swap back the message so go when on the iP5 are still there in the iP7+ once restored

    didnt know this thanks. Can iPhone 5 do iOS 10? Does it have to be on the exact same as in v10.1.1?

    Point releases are less problematic. It's just major version numbers.

    And yes, the iPhone 5 runs iOS 10. My wife's old iPhone 5 is on iOS 10 right now. I keep my own old iPhone 5 on 9.0.2 just to have it stay jailbroken though.

    Ah ok great thanks. How is iOS 10 on the iPhone 5? Run ok? Buggy? Smooth?

    Just keep your iPhone connected to Wifi while you have the sim card in your iPhone 5. Your iPhone 7 will get all the messages, emails and what not.

    If you go the route of backing up then restore back. Each version has to be on the same exact iOS version. Backups are very picky. If one of your devices is on 10.1.1 version 2 (14B150), make sure they both are.

    Don't think my iP7+ will now as was already on the original 10.1.1 whereas if I update my iP5 now suspect it will do the version 2

    If you plug the iPhone 7 into iTunes you will be promoted to install ver.2. You don't have to normally, but if you are going to do the backup restore route, I would do it.

    Ah ok thanks I'll do that then. Just plug it in and it will want to update? What is this version 2 anyway? Why?

    Apple didnt release a reason why there is a second build of 10.1.1. But we suspect for install issues. Thats why if you are already on 10.1.1 you don't need to update to the newer version. But your case is a little different. For the record I updated all my devices just so I would be on the latest and am not nagged by iTunes. No install issues on either version of 10.1.1 for myself.

    Well back with same question as such but now have an iPhone 6 16Gb as backup, and my iPhone 7 plus 128Gb. They are both on exact same iOS.

    As someone mentioned above, leaving my iPhone 7 plus connected on WiFi would not be feasible as could be away for 2 weeks and maybe run out of battery. This scenario is purely for when going away on holiday, leaving my iPhone 7 plus at home and using the iPhone 6.

    I would like when using the 6 to have my FaceTime and iMessage working. Emails I could just use the Gmail and web to get them. Apps not a problem.

    So I suppose it's if it's ok to have my AppleID on 2 iPhone's at once, so I can get my FaceTime and iMessage.

    You can do that. My Apple ID is on my 6s+ and my iPad Air 2. Whatever goes on via iMessage on my iPhone is reflected to my iPad. Sometimes there can be a slight delay, but otherwise it's 'synced'.
