How to Update iOS When iPhone Memory is Low

When iOS 11.0.1 was released, I was getting constant reminders from iPhone to update to latest version. There is no option to skip update, only available option is to schedule it at night or remind later.

I tried the wireless update, but got a message that says the update cant be installed as it requires more space than what is left on my device. Some options which was available after checking on apple support website, was to either clear up the cache and temporary memory on iPhone or to manually update it from iTunes. As my free space was less than 900Mb, as a first option I decided to clear up the temp memory and make space for updating iPhone.

In below article, I will show you how I Re-Claimed 3.5Gb & Updated iPhone When Memory was Below 100Mb. Listing out two methods to clear iPhone Cache & Update iOS

How to clear cache & temporary files from iPhone.

One method which I use it to manually check the storage settings (Tap Settings > General > Storage & iCloud Usage > Manage Storage) and see which app is consuming more memory than it should. In my case, Facebook was consuming around 700Mb, Instagram around 600Mb, so it was definitely some unwanted cache left behind from those apps consuming most memory. One workaround to delete these temporary memories is (if you have below 500Mb free space) to follow below steps.

1. Go to iTunes

2. Select Movies Tab

3. Select any movie and click on rent HD film.

4. After clicking on rent button, iPhone will try to clear all cache and temporary files so as to accommodate the film download. It will give an error showing film cant be downloaded because of low memory.

5. Check the storage option now & you can see more available free space.

Other option to update iPhone when you have low memory is to install update from iTunes.

  1. Install the latest version of iTunes on your computer.
  2. Plug your device into your computer.
  3. In iTunes, select your device.
  4. In the Summary pane, click Check for Update.
  5. Click Download and Update.
