    Our clients are running outdoor games using tablets. After upgrading iPad2-s and 3-s to iOS8 dramatic decrease in battery performance in cold is reported.

    People are claiming that after 1 hour in -5*C tablets are shutting down with peculiar "overheated" message. After warming up they come back to life.

    Previously iPads were really great in cold, beating Android devices by large margin.

    Has anybody encountered anything like that and maybe know if they issue is discussed somewhere? It seems like the way battery is monitored has changed in iOS8.

    We will run our own test as well (just trying to find iPads with old iOS still on them to compare).

    Thanks for any insight

    Thanks for the guidelines. They are clear and seem unchanged from previous ones. However the way iOS8 and iOS7 are acting in cold are very different.

    We made some additional tests side by side and while iOS8 switched device off in less than 60 minutes in -5*C, iOS7 goes on for hours (till the battery runs out).

    It is not probably an issue for majority of users, but for anybody using the devices out in cold constantly it is a major change.

    There is probably a sound reason behind the change which I do not see, as all the devices have survived cold very well. Any ideas how to get tthe info if it was a bug or intentional behavior?
