Fairphone gets very Hot and Battery drains quickly

Help Fairphone 1

Hello,
I did some changes for testing what could be the reason for this heating and fast battery drain:

  1. I removed the 64GB SD-Memory card - no change
  2. I deactivated the SIM2 - no change
  3. I deactivated the SIM1 - fairphone works normal.
    To verfy if it is the SIM-slot or the card I changed the 2 SIM-cards and did step 2. and 3. again - result: it was not the slot, it was the SIM-Card.
    By changing again with cleaning of the contacts - the phone works normally. Maybe it was a “bad” contact in the sim-slot which caused the heating and battery drain.
