Minecraft use 9 GB of storage space on my device

I expect that the 8.25 GB includes all your worlds, add-ons, and marketplace content. World saves can be quite large if you do a lot of exploring. This is especially true if you use Creative flying to explore for rare biomes such as mesa or jungle, because every chunk you see while flying has to be generated, and becomes a part of the world save.

You should be able to clean up unused worlds and other content using the Storage section in Settings. (You can safely delete purchased content you're not using; you will still be able to re-download it later.) If this doesn't resolve the issue, it would be helpful if you could attach screenshots of your Storage showing what you have installed.

Thanks for your response. I have one world and 3 templates i can’t delete. They don’t dissapear. 

The templates don't disappear because they're marketplace content that you own. However, we can see that the total storage used by these items is much less than 1 GB, so worlds and DLC are not what's using all your storage.

Are you perhaps talking about memory usage when the game is running? That's different from storage, which is persistently occupied by files. Memory, on the other hand, is transient (it's released when the app exits). It's normal for an app to use ALL available memory when it's running, because that makes it much, much faster. It will run with less memory, but possibly a little slower. And again, the memory is allocated to it only when you're actively using the app, so it doesn't prevent you from installing or using other apps.

If you're not talking about memory, where is the 8.25 GB figure coming from?

Iphones storage overview. 

If i connect my phone to my computer i can se a folder named ”premiym_cache” kontaining 21011 files 7.5 GB total

Good, you found the problem! That folder contains your DLC. So the problem is apparently that you aren't able to delete the DLC from your device for some reason. I'll need to have someone look at this who knows more about how that should work on the iPhone.

I manage to delete 206 folders in ”world_template” using Nemo in Linux Mint and now storage used by minecraft is down to 758 MB

OO, I'm not sure that was a safe way to delete the content: You may have trouble downloading it again. But if not, it seems you may have solved your problem, though others may still experience it. Again, I'll wait for someone else to review this.
