For those that take and edit a lot of photos on your iPhone (or iPad), storage space can become a concern after a few months have passed. For those that use iCloud to do backups of your iOS device, this can also become a concern. I made a video (about 6 minutes long) that includes just a few tips that I use regularly. I’m sure there are far more that I’m not aware of.
The three main things I cover are storage space of photos themselves, apps that can take up storage space, and backup space on the iCloud. To get started you’ll open the Settings on your iPhone and then choose General > Usage. It may take a few moments (about 10 seconds on my iPhone 5) but you will then see a screen with a lot of information. The top most thing is the storage. It shows you how much is available and how much has been used.
In my case I’m doing OK right now since I still have 8.3 GB available. How much is that? A large game app might be 1 GB, and a 1000 photos taken with the iPhone 4S/5 built-in camera will be around 2 to 3 GB. So with 8 GB available, I can take a few thousand more photos. So I will keep taking shots. 🙂
