<p>For the past few days, I was getting notifications that my backup could not be completed due to insufficient space on iCloud. So I have checked apps that were consuming most of the storage by going to:</p>
<p><strong>Settings | iCloud | Manage Storage | Backups | Username&#8217;s Phone</strong></p>
<p>Here I could see that Photo Library and WhatsApp were the two largest space consumers in the list. (Unfortunately, I haven&#8217;t taken the screenshot for you to see this here). So, I have decided to clear many WhatsApp chats from various media, along with many items from my Photo Library. After I have backed up my Photo Library I have deleted almost all pictures from the phone. Even then I could see that the iPhone was still showing the wrong numbers for the next backup.</p>
<p>For instance, I have opened <strong>WhatsApp | Data and</strong><strong> Storage | Storage Usage</strong> and I could see here that WhatsApp was using less than 20MB of storage, while the iCloud backup was still showing more than <strong>1GB</strong> for WhatsApp, even though it was stripped down a bit but not much after I have cleared WhatsApp chats.</p>
<p>The same was with Photo Library, even though I had roughly <strong>300MB</strong> of pictures and videos, iCloud was showing that Photo Library has more than <strong>2GB</strong> of data to be backed up.</p>
<p>The current size was <strong>4.65GB</strong> and my next backup was showing additional <strong>1GB</strong> of required free storage and therefore I was getting warnings of used iCloud storage. At that point, I was close to buying additional iCloud storage as suggested but then I thought again as I was a bit skeptical about this.</p>
<p>What I did was:</p>
<p>Open <strong>Settings | Click on your iCloud username on the top | iCloud | iCloud Backup</strong></p>
<p>Now scroll down and delete click to <strong>Delete Backup</strong></p>
<p>Now go to:</p>
<p><strong>Settings | iCloud | iCloud Backup</strong> (it is currently set to OFF)</p>
<p>Now go back to:</p>
<p><strong>Settings | iCloud | Manage Storage | Backups | Username&#8217;s Phone</strong></p>
<p>Check the Next Backup Size which is now in my case <strong>1,59GB</strong>, not <strong>6,50GB</strong> that was before.</p>
<p>Now go back to:</p>
<p><strong>Settings | Click on your iCloud username on the top | iCloud | iCloud Backup</strong></p>
<p>Click Back Up Now to do a new backup. (Make sure you are connected to power supply and to a wireless network)</p>
<p>That should do the trick. I am guessing this is just another Apple gimmick to trick users into buying the additional storage space they don&#8217;t necessarily need.</p>
