As is usually normal, Apple launches New security updates Regularly, which makes, after a few years, their old devices are not able to endure them, and have to stop giving that support to certain types of terminals.
This is what would have happened now, with the last update of Icloudthe Apple cloud that will cease to be present in several operating systems, so you must check if your iPhone is updated to a more recent one, whenever possible, since some models, not even can.
Obsolete iPhones without support for Icloud
Apple has stopped offering Icloud support to devices that follow in iOS 10 and macOS Sierra. That means that functions such as backup copies in ICloud, photos in Icloud, Keychain (Keychain), Icloud Drive and “Search for my device” will stop synchronizing or work properly in equipment that does not update.
If you have a iPhone 5, an iPhone 5C or a fourth generation iPad (The models that stayed in iOS 10) can no longer use those services in the cloud, because you will not be able to update to a compatible version. The same goes for Macs that continue in Sierra and cannot update to high Sierra or a newer version, they will lose access to many ICloud tools.
Apple usually does this to be able to concentrate on safety and new functions in more recent systems, and the consequence is clear, since users with old hardware remain without synchronization, without automatic copies and with less options to recover data from the cloud.
If your device can Update to iOS 11 OA High Sierra (or superior), updating as soon as possible is the most direct way of maintaining ICloud working; If you cannot, the alternatives are manually copy files to a third -party disk or service and consider changing device when possible.
In summary: If you depend on ICloud for photos, passwords or backups, check if your team supports the update. It is true that the models that do not support it, are very old, but you could have an old mac or iPhone at home, where you keep information that you never went to pass, and you think it will be there forever, something that may not happen, so we recommend you make the copy now, and try to keep everything possible in your new device.
And you, are you one of those who always have an updated model, or keep working with old computers? The truth is that the iPhone and Mac have a very long shelf life, however, Apple knows when to end it, and ago more than 10 years that these models came out, so we understand that it can be time to think about improving security, and not so much to continue extending their usefulness, although you can continue to open apps and games in them, as long as they do not also require a more current version, something that happens with banks of banks or that requires certain security or that requires certain security, which may require certain security, which requires certain security, which requires certain security, which requires certain security, which they can You change mobile because of it.
