16GB iPhones or iPads don't really have 16GB of available storage. Instead, it's more like 13 GB.
That's because some of your device's storage is being used for important things that make it work, like the iOS operating system.
The following steps will help you maximize the little space you have left on your iOS device, and you should be left with quite a bit if you follow all of them religiously.
Pick and choose what works best for you and your iOS life.
Turn off iCloud Photo Library and download Google Photos.
It may seem counter intuitive to download an app when you're trying to save on storage space, but Google Photos is key if you take any photos or videos at all with your iPhone.
With its free unlimited storage, you can save every single photo you take to Google's servers with Google Photos. After that, you can delete them from your phone's storage to free up space.
Sure, Apple's iCloud does the same thing as Google Photos, but you only get 5GB of free storage, which fills up very quickly and often results in annoying popup alerts telling you your iCloud storage is full.
Turn off iCloud Photo Library by going to Settings > Photos & Camera >disable iCloud Photo Library.
Unfortunately, photos don't automatically delete themselves from your phone once they've uploaded to Google Photos, so it'll require some manual maintenance every once in a while.
Delete videos you no longer watch or need.
Like that movie or TV show you loaded onto your iPhone or iPad for that flight you took last year. And while you're at it, do you really need that music video? It might be a work of art, but if your iOS device only has 16 GB, you need to set your storage priorities straight if you're running out of space.
Just head over to the Videos app, tap Edit on the top left, and tap the red Delete button next to the video you're deleting.
Don't worry, they'll be saved in iCloud separately from your free 5 GB limit. You can also use Google Photos to upload your videos.
Disable My Photo Stream and don't subscribe to others' shared albums
My Photo Stream will automatically send photos you've taken with one Apple device to any others connected to your iCloud account. For example, a photo you take with your iPad will end up in your iPhone and vice versa.
The iCloud Photo Sharing feature lets you automatically send photos in iCloud to friends and family who subscribe to you. It also works the other way around. Constantly receiving photos from others may be nice, but it'll also fill up your iOS device's storage.
To disable these features, go to Settings > Photos & Camera > and disable My Photo Stream and iCloud Photo Sharing.
