Hi there,

I get all that about technology advancing to require more and more storage space, faster chips, etc. I’ve been using a Mac since it was the size of a shoebox and had no hard drive, so I’ve experienced it happening for many years. As I explained previously, however, I don’t keep locally stored data on this iPad. I cannot plan for Apple’s future needs, since I do not know what they are, so it would not be possible for me to estimate that need going forward. I would, however, like to know why the OS and system data take up an inordinate amount space on this iPad and how to address that. I would also like to know how to avoid having my photos and videos stored locally on this iPad when they in fact reside in iCloud. Thank you.

Clearly, nobody can foretell the future - other than to reliably predict that as technology and Operating Systems develop, greater demands will be made upon hardware resources that are intrinsically a fixed commodity. Unlike some computers, iPad and iPhone cannot be upgraded as needs and OS evolve. Whatever you purchase is fixed for the usable lifespan of the device.

The other known certainty is eventual technical obsolescence. Unlike many other manufacturers, Apple typically provides full support for its devices for five to seven years from release of a specific device model - and security software updates for considerably longer. During the period of full support, you can be confident that a device will continue to be fully usable - within the obvious constraint of initially choosing a device specification that meets your storage needs. It is often the case that storage needs are either underestimated, or for some not even considered at the time of purchase - cost alone being the initial focus.

Your iPad Air5 is now around four years old - and is within the period of full support from Apple. As such, system software updates are regular - introducing new features and functionality as the OS develops. Along with capabilities that are potentially unwanted/un-needed by some users, this development all contributes to system "bloat" that over time may negatively impact performance and usability of devices that are resource constrained.

The advice offered within my replies is designed to both highlight the need to consider storage needs - and, importantly, provide a strategy to provide sufficient margin to accommodate predictable trends in increasing demands of the OS as it develops of the useable lifespan of the device. This does, of course, require the initial needs assessment to have been carefully considered - but the outlined strategy is designed to build-in a strong safety margin.

As already outlined, within this Support Community we often see tales of woe and discontent as available storage is exceeded for whatever reason. By contrast, we never see complaint from happy users because they have "too much" available storage.

Other potentially unhelpful commentary within this discussion, while usefully highlighting their own positive experiences with budget-friendly device configurations with which they are content, fails to recognise that the situation in which you find yourself cannot be resolved by their personal attack upon sound advice. I by contrast have carefully and consistently outlined the issue that you have encountered - and provided strategies to (a) "manage" your current difficulties and (b) plan for potential future replacement of your iPad at a time that suits you. Hopefully some food for thought.

Returning now to your final question...

While iCloud can be used for storage of files and photos, it is essentially a file synchronisation service. While it is possible (with some effort) to storage standalone copies of files and photos solely in iCloud, in common usage both iCloud and your Apple device(s) will each maintain a copy of such data. This serves multiple purposes in providing consistent access to files and data from any device/computer where you are signed in, an accessible backup should a device fail or be otherwise unavailable - and provides local access to this data whether or not you have an active network/internet connection.

As an immediate workaround for your issue, recognising that device replacement is not on your immediate horizon, consider the update path already described by ensuring that you (1) have a current backup, (2) reset the iPad, (3) perform the OTA update, and (4) restore your backup to the iPad.

As none of the system storage that currently impacts usability of your iPad is backed-up, the erase/reset/restore process will completely purge this "used" storage from your iPad - and in so doing provide breathing-space. While iPadOS will again use available local storage for cached data over time, you should regain a usable iPad for at least a manageable period of time.

Regrettably, you may struggle with an iPad that has so little internal storage. The 32/64GB devices are primarily intended for use in Educational settings, or in environments where the ability to store local data on the device is not required.

It is generally recommended that you maintain at least 4-6GB of free space at all times - as your iPad needs some temporary space to complete many tasks. When performing system software updates, you may temporarily require more...

A system software update requires sufficient space to be downloaded, unpacked and verified prior to installation - major version updates requiring considerably more space than an incremental point-update. The required space, to perform an OTA update, is typically double the stated space for the installed update; after the update is successfully completed, temporary files are automatically deleted - returning free space.

If your internal storage is full, or is insufficient for the task that you need to perform, your only option is to better manage the storage that you have - and delete unused Apps or unneeded data.

External storage options can often help with managing limited internal storage. Depending upon your iPad model, the iPad will either have a Lightning or USB-C port - and may therefore require either an Adapter or USB hub to connect the USB Storage device. If your iPad has a Lightning port, you’ll need an Apple Lightning to USB3 Camera Adapter:

Using a Mac computer or Windows PC can help with system software updates - as the update package is initially downloaded to the computer, unpacked and verified by the computer, prior to the computer installing the updated system software on the target device.

As is, perhaps a workable remedy is to ensure that you have either an iCloud or iTunes backup of your iPad - and then completely erase the iPad. With no user-data present, you should be able to update the iPad; once updated, you can restore your backup to the iPad.

Erase all content and settings:

Settings > General > Transfer or Reset iPad > Erase All Content & Settings

After the reset, set-up the iPad with your AppleID - but do not restore the backup. Perform the system software update using whichever method works for you.

Finally, restore the backup to your iPad:

iOS seems to be taking up an inordinate amount of your space. On my iPad A16 recently upgraded to 26.6.1, iPadOS is only using 12.7GB.

If that does not help, look at apps you have installed. Some useless aftermarket "protection/security" apps will rob you of resources. Google apps can also be resource-greedy. Anti-virus software, so-called "cleaning" apps, and client-side VPNs† will also slow your device with the only benefit going to the develpers' bank account.

Thanks for your detailed reply. This is a 64GB 5th generation iPad Air that I keep in my kitchen for bringing up recipes, doing crosswords, checking social media, etc. I don't deliberately store anything on it. It does have about 5GB of free space, but apparently the update needed more. It seems to me that the iPad OS and system data take up too much room. Do you agree? Can I do anything about that?

I use my 27" iMac (1TB HD, 40GB RAM, 2TB external backup) for actual work. So I frankly don't want to take the time to erase this iPad just to update it and then restore it. But it finally did the update, so I'm good for now. I guess it took a while to optimize its storage.

You are very welcome.

As previously outlined, to perform an OTA update, you typically need around double the stated space for the iPadOS update that you are attempting to install - this providing the temporary space needed to download unpack and verify the update package prior to installation. Once successfully installed, temporary files are discarded returning [some] free space to the iPad. Successful installation may also usefully result in some of the space used for System Data also being released.

If instead you use a computer to perform the update, the update package is downloaded and unpacked by the computer - and after verification, the update is installed by the computer to the connected iPad. This latter method requires less free-space on the target iPad than performing an OTA update.

In some cases, available space remains too constrained for an OTA update, or update using a computer. In such circumstance, erasing all locally stored data (after a performing a backup) prior to attempting the update clears sufficient space to permit successful update. After performing the update, the backup can be restored to the target iPad - completing the exercise. While this method can be effective in overcoming storage constraints in the short term, unless you can rationalise and reduce your locally stored data, you are likely to again encounter difficulties at some other time.

Recent releases of iPadOS make considerably greater demands upon available storage to improve system performance - this likely not anticipated when older devices with less internal storage were originally designed. The lower cost models, with minimal storage, were budget friendly at the time - but, with benefit of hindsight and greater demands by recent OS versions, have become problematic for many users.

Apple no longer markets any iPad with less than 128GB of internal storage.

Given the increased constraints, you might be well advised to consider replacing your iPad with a newer model that has more internal storage. Whichever iPad model you ultimately choose, you would be well advised to purchase as much internal storage as your budget might reasonably allow - as internal storage (and other hardware) cannot be changed, upgraded or extended. The available internal storage is fixed for the entire life of the device. If you run out of internal storage for your documents, photos and other data - as now - you will forever struggle and the iPad will become a source of frustration. It is far better to have more storage than you need, than to need more storage than you have.

When considering an iPad, a good rule of thumb is to quantify how much data storage you will need - add a healthy margin - then double it. If you are unable to quantify your data storage needs, it becomes more difficult. Whilst I and others cannot make definitive recommendations for your personal needs, objectively I would council against purchase of any iPad with any less than 256GB storage, 512GB and higher having a greater margin for growth.

Within the Apple Support Communities we see regular tales of woe and disappointment when storage requirements are exceeded, necessitating replacement of the device; by contrast, we never see complaint of having too much available storage. It is relatively easy to fill limited internal storage space; perhaps consider higher tiers of storage as providing room for growth as your needs develop or mature - potentially extending the useful usable life of the device.

This is up to Apple and what they predict that people will want. Newer models get the Liquid Glass effect on them regardless if the user wants or needs it. Yes, you can tone it down if you don't like the effect but you can't remove it from the device...all of these fancy "effects" take up system resources and storage space. Also, depending on the iPad model, newer models get Apple Intelligence either pre-installed or installed by an iPadOS update. Again, this can take up vast amounts of storage space and again while the user can "turn it off" if they don't want it, the AI models and everything else that it entails is happily stored on the iPad's internal storage. Turning it off does NOT clear the storage space that is being used until Apple and the OS feel the system needs these resources. This cutoff point is not judged or selected by the end-user.

I have various iPads, three of which qualify for Apple Intelligence and despite me turning it off, it still sits happily on my devices, taking up the storage space until a time that the OS feels it will free it up. I have zero choice in the matter. Same with Liquid Glass except as I mentioned above, the assets used by this eye-candy will simply not be freed up when the device feels it's necessary.

We buy what we buy at the point in time that we buy it. We buy what we can afford. Many say to over-buy when it comes to these things but as you've mentioned, one can't predict what Apple (or someone else) will be requiring in the future. Many of these iPads that are now considered "obsolete" (or as another member in the community likes to refer to them being meant for "educational" purposes), were top of the line, highest storage space devices at the time of purchase as little as two or three years ago. They are now deemed as bottom of the barrel "educational" devices.

Bottom line is you can not predict anything. Even over-buying (if you can) is no guarantee.

What proof do you have to back up this statement that you keep using? I purchased all of my iPads (even an older 16GB iPad mini 4, and more recently a 64GB iPad Air M1 as well as two 64 GB iPad mini 6's) at Best Buy or similar retailers and they were never marketed nor intended for use as being "primarily intended for use in Educational settings, or in environments where the ability to store local data on the device is not required". They were marketed as new and current iPads. Yes, their internal storage grows out of date depending on their age and apps growing increasingly larger as well as iPadOS ballooning to an ungodly size due to the silly new AI junk that's all the rage now.

These iPads were never marketed as you keep stating.

Today's iPads with 128GB of storage are not being marketed as "educational" or as your longer statement above reads...yet in two to three years, they will be in the same situation that the OP's iPad (and countless thousands/millions of others) are in today: that is, have smaller device storage than will be required in the future.

Stop spreading this misinformation...and update your boilerplate response.
