    I stopped using wireless charing after the heat melted my phone’s backplate off

  2. Hey IFixit Team! I just had a little criticism about the graph you showed at 4:07. Please use the correct size of bars as it would help you better to get your point across about how gigantic the the market is expected to be. Regards.

  3. Anytime there is an energy transfer there will be energy loss.

  4. I’m curious about wireless chargers (Qi2) with cooling fans and peltier element. Can you please elaborate on that in an update video? I use one in my car which doubles as a phone holder too.
