I'll try to collect a few patterns. Please comment if you observe anything not matching these patterns.

Random shutdown of the phone means that all of a sudden the screen goes black and the phone is off. You can hold the power button to normally switch it on, again, but it may soon die again, if you're unlucky.

Observed facts:

  • Cell-tower related. This happens only in certain areas, but happens pretty often then.

  • Battery level doesn't matter. It happens with >90% of battery, too.

  • It was only observed since OS 1.0.2.5.

  • Pulling the battery helps for some time (depending on whether automatic time updates are enabled or not).

  • Can die again after 32 hours (anything shorter observed?) after pulling the battery, if automatic time updates are off.

  • Can die again after 1 hour (anything shorter observed?) after pulling the battery, if automatic time updates are on.

  • Saw the "charge battery" screen once before shutdown. So it appears to be battery- AND cell-tower-related. Division by 0, triggered by a mobile connection, in some power consumption calculation for checking battery life..? Just guessing.
