Fairphone 3 suddenly stopped working. It won't turn on and won't charge, even with a new battery

Would this preclude the newly bought battery from working?

Yes a good point as I read somewhere the phone could work without the bottom module, and if that is so then you can remove it and try the batteries again

Regarding the batteries. The new one should have been partly charged and have a voltage around 3.6V, maybe you can find a shop that will test the voltages on both.

Please see this older topic/post

For the record: The FP3 (that Fairphone has lent me) will boot with all four small modules unscrewed (top, camera, bottom and speaker) and taken out of the device.
