iPhone memory problems

No, it's not normal, vishdeep.

I would try to install a fresh copy of your iOS.

To perform this operation, make a full backup of your iPhone's content, then restore it to factory settings, and at the end, set it up as new. Follow this support guide:

Restore your iPhone, iPad, or iPod to factory settings - Apple Support

When done, check the system storage, before restoring your data.

Then you can restore form your previously made backup, and check again.

Please keep me informed.

I thinks it's normal. iOS and built-in apps need 10-15GB of storage.

Sorry, I thought of free storage.

Well, you could have apps, data, pictures and media.

Can you take and post here a screenshot of your storage situation?
