My iphone 6 plus is bent and not powering on, need to retrieve data not backup to cloud

Solution 1:

There are companies out there, although I can't recommend any that claim to be able to recover data off broken iPhones, I've not tried them, the iPhone doesn't have a hard drive, the whole device is on a single computer circuit board, it's going to destroy the phone trying to get it repaired.

Data recovery is expensive, and once your phone has been modified by a third party the price for getting Apple to repair/replace your phone will escalate as they won't do an out of warranty service on a phone that has been modified by a 3rd party unauthorised centre.

In other words you'll have to buy a new phone, and fork out a load of money on data recovery.
