We all know the basic steps to increase storage on your iOS device (such as an iPhone or iPad)... remove apps that you don't use, delete photos, music and videos, delete old text messages, etc.
But what if you are running out of storage space on your iPhone and you don't want to delete anything? Here are some simple tips & tricks that will free up memory on your iPhone or iPad that don't require you to delete anything!
1) Move photos and videos to an iCloud Shared Album
Most people don't realize this but photos and videos in an iCloud Shared Album don't use up any memory on your device and they don't count towards your iCloud quota. Just create a shared iCloud album but don't invite anyone to view the album. Then you can upload your photos and videos to the album without worrying about using up any of your phone's memory or iCloud quota. You can create up to 100 shared albums and each album can hold up to 5,000 photos and videos regardless of size.
2) Clear your app cache by deleting and immediately re-installing apps
Over time individual apps accumulate temporary files and data in what is known as a "cache". For example, the Google Search app starts out at 95MB when you first download it. After several months of regular Google searches the app can swell up to over 300MB. Even if you "kill" an app by swiping it away in the app switcher, the cache will not be cleared. Unfortunately the only way to effectively clear an app's cache is to delete the app and then immediately re-install it. Examples of apps that may have a bloated cache are Google Search, Facebook, Chrome Browser, Spotify, and Flipboard. I have freed up several hundred MB per app using this method.
