Q: iphone6  64GB loss of storage

Hi largalarga007,

Thanks for using Apple Support Communities. Based on what you stated, it sounds like you are low on space on the iOS device. I would recommend that you read this article, it may be able to help the issue.

See how much storage you've used on your iPhone, iPad, and iPod touch - Apple Support

Tap Settings > General > Usage > Manage Storage. You'll see a list of your apps, and how much storage each one uses.

Cheers
