HTC Desire Shuts Down On It's Own

CUSTOMER-


my HTC desire does a full shut down after about 15 minutes use Already Tried:
soft, - then hard reset cleaned all contacts treatment with antistatic spray


Dimmusacio-


Does it give you an error message at all?
Does the battery indicator say full or empty when this happens?


CUSTOMER-


- tried with battery fully as well as about half charged; - does not seem to make a difference.
- no error message appears; it just shuts down and about a second later turns on the routine with the white page with 'HTC' in the middle; - sometimes it continues the 'turn on' process from here and asks for the 'SIM-card' code; - after getting this it will work normally for about 15 min. for then to arbitrarily again perform a full 'shut down'.

Let's try a hard reset. First backup all your contacts and anything else you need to save from it. Then follow these steps.
  1. Turn the power off. If your HTC Desire is frozen, pull the battery out and reinsert it
  2. Hold the Volume Down button
  3. Press and release the Power button
  4. You are now presented with a menu that allows for Fast book, Recovery, Clear Storage, and Sim lock
  5. Select Clear Storage by pressing the Volume Down button
  6. Press and release the Power button
  7. Now simply confirm your decision: Volume Up for YES
Now test it again and see if the same thing happens. If it does and you are using a micro sd card remove the sd card and test it. Sometimes the sd cards get corrupted and will cause this to happen if it works properly without the card you will need to replace the card. Another possibility is that your sim card is failing and needs to be replaced in which case you would need to get a new ones from your provider.
