When you ask about recovering data,is your iPhone damaged or did you accidentally delete something?
The other answer is helpful on here.
However,if your iPhone is damaged,and won’t power on,you can’t really recover the data.
JESSA JONES is very capable of repairing iPhones. She associates herself with ifixit. She owns the website ipadrehab. She will work on iPhones,as that’s her specialty. If it’s water damaged,she would maybe look at it,but you’d need to contact her.
Anyways,good luck. If you have other questions,let me know.
