Why does my iPhone keep saying 'iCloud storage almost full' — and how do I fix it without paying?

That warning is almost never a mystery: device backups and Photos eat nearly all the space. Slim the biggest apps out of your backup, clear large Messages attachments, delete old device backups, and empty Recently Deleted — or back up to a computer for free instead of buying a bigger plan.

You're packing for a trip, you try to back up your iPhone first, and up pops the warning: “iCloud storage almost full.” Short answer: The warning is almost never a mystery — it is usually your device backups and Photos eating the space. In most cases you can free up plenty of room in about ten minutes, without buying a bigger plan. Here is why: your iPhone backup quietly updates itself, often nightly, and it can grow enormous without you noticing.

Every app included in that backup adds its data to the pile, so trimming the biggest apps out of the backup usually frees far more space than deleting photos one by one.1. See what is actually using the space. Go to Settings > [your name] > iCloud > Manage Storage.

Backups and Photos are almost always the top two — start there instead of deleting at random.2. Slim down your backup. Tap Backups > This iPhone, then Show All Apps, and turn off backup for large apps you do not need preserved — games and streaming or social apps simply re-download their data anyway.3.

Clear out Messages attachments. Go to Settings > General > iPhone Storage > Messages > Review Large Attachments, and delete the biggest old videos and GIFs people have sent you.4. Cull the camera roll.

Delete screenshots, duplicates, and burst photos you do not need, then empty the Recently Deleted album so the space actually comes back.5. Remove backups of old devices. If Manage Storage lists backups for phones you no longer own, delete them — they are pure dead weight.6.

Or back up to a computer for free. Plug into a Mac and back up with Finder, or a Windows PC instead, and skip the iCloud storage squeeze entirely.Common mistake: Do not delete your only backup before checking whether iCloud Photos is turned on. If Photos is off, your whole camera roll lives inside that backup — deleting it could delete your only copy of your pictures.Ad’s take: Apple would love for that warning to nudge you into a monthly payment.

Nine times out of ten, ten minutes of housekeeping fixes it for free — try that first.
