You don't have to spend any money to get a faster iPhone.
If you downloaded IOS 11, you have all the tools you need.
We'll start by going to settings, general, and select iPhone storage.
Here, you'll see a list of tips.
Photos are the biggest offenders for most people.
The easiest ones to get rid of are the ones in your recently deleted folder.
Want an even faster phone?
Upload your entire camera roll to iCloud, Google Photos or your computer and keep only your favorites on your iPhone.
Now make sure your new pictures don't take as much space.
In settings go to camera, format and enable high efficiency.
Let's move on to messages.
You can automatically clear old messages after a year by clicking enable.
And delete any attachments that were sent to you and could be weighing you down.
And last, take a good look at the list of apps and the dates you last used them.
Now pretend you're cleaning out your closet.
If you haven't used in over three months, toss it and enjoy all the new features of iOS 11 in your faster phone.
