Written by Hassan Abbas

Are you wondering to limit “System” storage size on iOS devices? If you have ever try to visit the section of iOS Storage of Settings app on an iOS. Then you might notice that the “System” storage section is oftenly quite large and can take up a huge amount of storage capacity. For additional-large storage capacity devices, this might not be a big deal. But if you have “System” taking a space of 16GB on a 32GB device then it’s a storage burden that is affecting total device capacity. Also, it securing other uses of the device because of being unable to install apps, media, games, or other stuff to the device. Therefore, limiting a large “System” storage section of iOS devices could be desirable.

This tip can cover a somewhat unusual way to limit the size of “System” storage that is found on the Storage settings of an iOS.

Checking Current “System” Storage Size in iOS

Before moving further, you probably want to get an idea of how large your current “System” storage is before trying to limit the capacity. Also, it’ll provide you a reference point to work with. You can also check System storage size by doing the following:

Step 1:

Head over to the “Settings” app on iOS then move to “General”

Step 2:

Select ‘iPhone Storage’ or ‘iPad Storage’

Step 3:

Wait until the storage usage to calculate, then move all the way under the Storage screen to find “System” and its total storage capacity consumption

“System” can be quite different in sizes, certainly it’s 7 GB or so. However, it can very easily be 10GB, 15GB, or also a huge 25 GB or larger too, often even on the same device type. That apparently random but the storage usage makes “System” a bit like the “Other” storage. However, they are frustrated by some users after consuming device storage in iOS.

Now you must know how large your “System” storage is from the start. Come let’s take a look at the process that might help to limit that storage size.

How to Reduce the “System” Storage on iOS

How to Reduce Storage Size

If you want to use this trick to reduce the “System” size of your iOS Storage. Then you wnat the iOS device. However, a PC with iTunes, and a USB cable to connect the device to the PC. After having all of that, the rest is quite simple.

Step 1:

Head over to iTunes on the PC, it can be Windows PC or Mac.

Step 2:

Then plug the USB cable to the PC, and then attach the iPhone or iPad to that USB cable

Step 3:

Now unlock the iOS devices after entering the device’s passcode. In case, if you’ve never connected it to the PC before you want to “Trust” the PC when that pop-up shows up

Step 4:

Simply leave the iPhone or iPad connected to the PC via iTunes open for a few minutes. Also, you don’t want to sync or anything just let it sit

Step 5:

Launch the “Settings” app then head over to “General” and to the “Storage” section of the device, moving all the way down to view “System”. As it should have recalculated and often limited in size considerably

Step 6:

Simply disconnect the iOS from the PC and USB cable and enjoy your latest free storage space.

Why it works isn’t completely clear. But whenever you connect an iPhone or iPad to a PC and open iTunes. It can perform some maintenance or cleanup behavior that dumps caches or temp files from the iOS System section. Perhaps during preparation for a recovery to iTunes, and when completed it can free up a huge amount of storage capacity on the device.

In my case, I can free up over 5 GB of storage on an iPhone just by plugging it into a PC with iTunes and allowing it to sit for 2 minutes while unlocked. But on the iPad, I can free up 2 GB doing the same action.

This technique is not guaranteed to work, however, and on an iPhone X with a huge 25.6 GB system size. It just freed up less than 1 GB. Some users might report more dramatic modifications in the size of “System” but there do not looks to be much rhyme or reason involved.

What do you know about the “System” storage?

The “System” section of the iOS Storage is precise, it’s system software. However, it includes iOS itself, which is the core operating system executing on the iOS devices. It includes all system functions, system apps, and other system components such as temp files, caches, and other underpinnings of iOS OS.

The huge storage consumption size of the “System” section of iOS Storage is a type of nebulous “Other” storage section of iOS devices. They are still mentioned in the Storage section of the Settings app. But it seems that “System” is now contained within the “Other” section.

Another choice that shrinks down the iOS “System” storage is more dramatic. Simply remove the device, then reinstall iOS and backup them. However, that’s a significant undertaking, however, so that shouldn’t be the first resort for anyone. Also, restoring iOS will limit the “Other” capacity on an iPad or iPhone.

Other iOS Storage TRicks

The major complaints iPhone and iPad users often have relates to insufficient storage space on their devices specifically on smaller storage size versions with 16GB and 32GB capacities. But also with 64 GB, 128GB, and 256 GB devices too, relying on how much stuff is on there.

If you try to make “System” storage space to limit general storage usage on the iPhone or iPad. Then you might also be interested in learning how to erase or remove “Other” Storage on an iPhone or iPad with removing “Documents & Data” from iOS apps. Other amazing tips for freeing up storage on iOS devices include offloading apps from iOS that are not in use, removing apps that are unused, turning on automatic offloading of unused apps, and focusing on wiping “Documents & Data” from apps on the iPhone or iPad specifically with apps such as Instagram which have large caches taking storage on the iPhone.
