Dead iphone photos

Hello,

Start here to see if you can get your phone to turn on:

If your iPhone, iPad, or iPod touch won‘t turn on or is frozen

If you have iCloud photos turned on, they should be in the cloud:

Get help with your iCloud Photo Library

Good luck.

Get the battery and charging port replaced. Then try plugging it in. Or load a back up onto a new phone

No, the phone needs to be on to be able to access anything.
