Whether you take advantage of Apple's 5GB of free iCloud storage or subscribe to any of the paid plans, it's essential to know more about your iCloud quota on the iPhone and Mac. That knowledge helps you effectively manage the data stored in iCloud and skip shelling cash for additional storage by regaining wasted space.
Despite looking complicated from the outside, your iCloud storage comprises of four main categories of data—iPhone backups, iCloud Photos, iCloud Drive, and general app data. Let's dive in and check them out in detail.

By default, your iPhone is configured to back up data to iCloud so that you can easily restore your device in the event of data loss. That happens when you charge your iPhone, although you can also initiate backups manually. iCloud backups are incremental so you won't see multiple backups of the same device.
To tone down the size of iCloud backups, you can remove unwanted apps included within them—go to Settings > Apple ID > iCloud > Manage Storage > Backups to do that.
You can also turn off iCloud backups completely and free up lots of space quickly—make sure to back up your iPhone to a PC or Mac regularly in that case. However, we don't recommend that.
iCloud Photos can take up the bulk of any iCloud storage plan, especially if you shoot lots of photos on your iPhone. It takes a backup of your images (separately from regular iPhone backups), and syncs those photos to the iPad and Mac so that you have ready access to them across devices in real-time.
You can also significantly reduce iCloud storage consumption by turning off iCloud Photos and switching to Apple's My Photo Stream, which syncs your images (up to 1,000) between devices without using up your quota—go to iPhone Settings > Photos to do that.
If you regularly use iCloud Drive on your iPhone or Mac to store files, it may consume a lot of storage. You can review your iCloud Drive files and delete unwanted items via the Files app on the iPhone or Finder on the Mac.
Tip: You can access iCloud Drive contents on the PC via iCloud for Windows or the iCloud.com web app.
iCloud storage is used by various (mostly native) apps and services to sync data between devices. They include Messages, where storage consumption can go up to multiple gigabytes due to iMessage photos and attachments—same goes for apps such as Notes, Mail, Pages, and so on. Other apps that also use iCloud, but take up less storage, include Safari (to sync browsing data), Contacts, Reminders, etc.
On the iPhone, go to Settings > Apple ID > iCloud to check and manage the various apps and services that use iCloud storage. You can also determine how much storage they consume by tapping the Manage Storage option (located within the same screen).
On the Mac, go to System Preferences > Apple ID > iCloud to check and manage the apps and services that consume iCloud storage.
Unlike with iCloud Photos and iCloud Drive, you have no alternative means to sync data among your iPhone and Mac if you prevent these apps and services from using iCloud. You must also avoid turning off iCloud for services such as Find My since that can put your devices at risk.

Since you now have a better idea about what iCloud is used for on the iPhone and Mac, you should have an easier time dealing with a limited storage quota. However, think through clearly before disabling major features (such as iCloud Photos and automatic iPhone backups) since lost data could be irrecoverable. If you are seriously crunched for storage, try using Google Photos and Google Drive alongside iCloud (for backups and app data) to avoid an immediate upgrade while still keeping things in sync.
