"How long does it take to backup to iCloud", people ask. The answer is that iCloud backup speed is related to the size of your backup and the speed of your Wi-Fi connection. The smaller your backup and faster your Wi-Fi connection is, the faster your iDevice will back up to iCloud. So there is no accurate for iCloud to back up. But if you have questions like "Why is my iCloud backup so low" or "Why is my iCloud backup taking too long", there are indeed some measures you can take to make your iCloud backup faster or you can choose an alternative way to back up your iPhone/iPad instead of using iCloud.
If you intend to back up your iPhone, iPad or iPod Touch and your iDevice is running sluggishly, you'd better clean up your iDevice first before you back up your iPhone/iPad/iPad Touch to iCloud. You can visit the article that details the tips to speed up your iPhone/iPad to know how to make it.
As I mentioned above, the time it takes to back up to iCloud partly depends on the size of the backup. So you can choose not to back up the large files to avoiding iCloud backup taking too long. Besides, given that only the first 5GB of iCloud storage is free and backing up large files to iCloud can easily eat up the free iCloud storage, it's a good choice to backup your iDevice to the computer with iTunes.
The other factor that will influence iCloud backup speed is the quality of your Wi-Fi connection. If you get your iDevice under a good Wi-Fi connection, it will surely make your iCloud backup faster.
