It is hard to imagine a world without iPhone. However, that world was a reality prior to 2007 (only 9 short years ago). In 2007, the very first iPhone was introduced to the world. In the beginning, the iPhone storage capacity was offered in 4, 8, or 16 GB. As new iPhones were introduced in the market, storage capacity grew. For instance, the 3GS offered up to 32 GB of storage. It became apparent that 4 GB would be useless and was taken off the options list, replaced by the newest storage capacity of up to 256 GB in the iPhone 7.

Check Your iPhone Storage Capacity

Method 1 On iPhone Itself

Whether you are checking the storage capacity of your iPhone 7, or an earlier model, such as the 6, 6s, 5 or 5s, checking from your iPhone itself is as easy as 1, 2, 3. Follow these easy steps to see not only your iPhone used storage capacity, but how much capacity you have left?

Go to Settings > General > Storage & iCloud Usage > Manage Storage.

You will see, how much iPhone capacity is used and the total number of available storage capacity. Below that, you have a list of all the apps and cached data and can see exactly how much storage each is using.

Method 2 Via iTunes

Should you choose to check your iPhone 7 capacity (or any other iPhone capacity) from iTunes, you can follow these steps to determine the same data as above:

  1. First open iTunes on your computer and connect or sync your iPhone.
  2. Select your iPhone in iTunes.

3 Tips to Optimize Your iPhone Capacity

Whether you are over iPhone capacity, working to increase the iPhone 6 capacity, iPhone 5 or 5s storage capacity, or even the iPhone 4 capacity, there are several tips that will help you maintain your data without having to upgrade your entire phone.

1 Store in iCloud

One of the first way to optimize your iPhone capacity is to enroll in iCloud Drive and then put it to work for you. iCloud Drive is the best place to store your photos and videos and free up some space on your iPhone at the same time.

Go to Settings > Photo & Camera, and switch “iCloud Photo Library” to on position. Check “Optimize iPhone Storage”. Then the full-resolution photos and videos are automatically replaced with optimized versions. Don’t worry. The full-resolution versions are stored in iCloud.

2 Use USB Flash Drive

Take advantage of external storage options. The iPhone capacity is limited by the phone you purchase and you cannot add a memory card. However, that does not mean that you cannot add external storage options. While not as helpful as the cloud, there are several external memory drives that are portable and act as a USB drive type device. This is perfect for those stubborn iPhone 5's with storage capacity of 16GB.

3 Reduce Camera Pixels

While the more pixels of a photo or video make for a better viewing experience, it can cause your iPhone to go over storage capacity. Therefore, it may be wise to change the pixel settings for your camera to increase your storage capacity abilities without eliminating your ability to take and store photos and videos.

It is very simple. Just enter your Settings and select Photos & Camera. Then select Record Video and reduce your pixels on the videos you record.
