Apple have quietly added a tier to their iCloud storage options, 2Tb. It makes sense I guess with the possibility of setting the base level iPhone at 32Gb and some suggesting that a 256GB iPhone may appear to join the 256GB iPad Pro. Not to mention the new feature of macOS Sierra that lets you store your Documents and Desktop folders in iCloud, to be synced between all your Macs. With people generating more and more data and (wisely) backing it up the bottom tier of 5Gb free looks pretty paltry. After all I'm sure that the revenue generated by iCloud storage doesn't amount to anything significant for Apple why not allow us low level users access to a bit more for free. Personally I use iCloud Keychain, iCloud Drive (to sync my Password manager), Mail (which I don't use), Contacts, Calendars, Reminders, Notes and the essential Find My iPhone. The whole lot only uses 1.5 Gb but I would use a lot more if it was free. If I add iCloud Photo Library for example I am well, close the limit. I used to use it but I got sick of being constantly bugged by messages that I'm almost out of space to store my backup, along with a threatening dialogue box encouraging me to upgrade my storage plan or I won't be able to use my iCloud email service. In fact given that I have 64Gb storage on my iPhone 5s it might not be unreasonable to expect a base level of 25Gb.
