I'm procrastinating at work, noticed something weird.
When the phone is charging, I glide my fingers across the back, and feel a faint charge, kind of like the phone is vibrating. Maybe my fingers are super sensitive to the grooves in the finish? I don't know.

As an engineer, let's go about this scientifically.

  • Naked HTC One M8 (Gunmetal) with Spigen Tempered Glass Protector
  • OEM HTC Charger that came with the phone
  • Plugged in to a surge protector. The only other thing plugged in is the AC Charger for my HP Elitebook
  • Phone is face down while plugged in on wooden desk

  • Gently glide finger across the back of the phone.

Anyone else feel this? Or am I going crazy at my government job?

Next step is voltmeter and phone case vs ground. It's possible that the charger isn't properly grounded, so although it only delivers a potential of 5V, those 5V are sitting on a 50Hz sine wave of, maybe 30-50V (thats a guess based on my experience of electrical shocks).
