Service Description

This service is to replace the USB/Lightning detection IC, commonly known as the “U2 IC”.

This is a common part to fail with use of cheap wall chargers, car chargers, iPod docks, and other power sources.

The common symptoms for an iPhone 6/6+ Tristar IC issue are:

  • Battery won’t charge once flat.
  • Battery won’t charge past X percent.
  • Accessory not supported messages.
  • Rapid battery drain.
  • Not charging/Not detected via USB.
  • No power at all.
  • Error 9 during restore.
  • Low current draw/slow charging
  • Device says charging but percentage goes down
  • Device says charging when there is no cable inserted (Fake Charging)
  • BSOD (Blue screen of death)
  • RSOD (Red screen of death)

The IC will be replaced with a newer revision from the 6S/6S plus, 1610A3. This will decrease the chances of it failing again, but you should still discard of any non original chargers.
