Issue with iPhone's Updating .
The fact is My phone started to Keeps Turning On And Off By Itself. I decided to connect my phone to my Macbook maybe can help through iTunes but unfortunately nothing happened .
I searched on google and found out I have to press two bottoms at the same time and keep it until something pop up on my iPhone's screen but actually it came up on my MacBook's screen . (The picture I have upload at the bottom here ) .
I started to update my iPhone XS Max (256 Gb ) , But it didn't work . I think it's because of my phone's storage which is almost full , 255.50 of 256 Gb . I was wondering how can I take all the storage I have without removing them. I don't want to miss my documents, photos and information , Although I know my iPhone does not turn on ... ? Please if anyone can help me out.
(Not sure if My iCloud was on or not but anyway it was only 3 or 4 GB)
(When I connect my iPhone , my MacBook can recognize my iPhone but my iPhone is still off)
