Below you can see the two separate booking ins in which it is clearly stated what the very exact single issue was and still is. The Battery!
A few screenshots of the daily battery/power cut offs (at 14-20% capacity) that are occurring still even after having sent it, exactly as demanded, for weeks at a time, to HTC's repair centre, TWICE!
The exact phone as it was before sending to HTC. It is real and is in my possession still defective as it was at the start of this process within it's warranty period and receiving it back after considerable delay and inconvenience.
The address that handles their book ins is: Hinchingbrooke Business Park, 1 Kingfisher Way, Huntingdon PE29 6FN. This is one place to avoid even if used for another company's device.
