Apps that take up a lot of storage space are also usually responsible for slowing down your device and making it run less efficiently. When these apps suck up all the storage, it also leaves less storage space for things you really want to do, such as shoot video in 4K or take more photos or even download large attachments and files.
We know it can be difficult to decide which apps to part ways with — you may never know when you’ll want them back. But the good news is you can always offload apps or delete them and then download them again if you change your mind. In the meantime, you’ll get to see if the app’s absence makes a noticeable difference in your storage space and how your phone runs. Before you delete anything, go to Settings > General > iPhone Storage. Scroll down to see your phone’s calculation of how much space each app absorbs. Chances are one or ore of these six apps will be listed.

1. Social Media Apps
To call social media apps like Facebook, Instagram, and Snapchat absolute storage hogs isn’t an exaggeration. These resource-intensive apps are constantly updating and providing new content, plus they contain large files like photos and videos.

2. Podcast
The problem isn’t the Podcast app itself — it’s the number of podcasts that may be automatically downloading onto your app by the day, all of which are taking up storage space. If you never delete anything, these files add up quickly.

3. Photos
You aren’t going to delete the Photos app (of course). It’s important for storing all the photos and videos that you take. But you could be unknowingly allowing it to take up far more storage than necessary by never deleting anything or moving files over to the Cloud before deleting them from the app. Taking Live Photos or photos in high resolution also takes up more space.

4. Games
Games, especially those with intense graphics, consume storage space and battery power on your device. The fewer games you keep on your phone, the better for storage — games with less complex graphics are a safer bet.

5. Streaming Apps
Love your Netflix, Hulu, and HBO streaming apps, and not eager to get rid of any of them? These apps take up a ton of resources to run, but they also consume storage when files accumulate and are never deleted.

6. Message Attachments
Whenever someone sends you an email with an attachment, it is subtracting more storage space from your phone than an email without attachments. Instead of going one by one, you can use iPhone storage settings to delete these messages in bulk. Go to Settings > General > iPhone Storage. Tap Messages. Under Documents & Data, you’ll see sections like Photos, Videos, GIFS and Stickers, and Other. Tap into a section and click edit to begin deleting these messages.
