Samsung Galaxy Nexus (Verizon) with Android 4.1.1 (unrooted).
I seem to be having unusually frequent reboots of my phone; sometimes multiple times in a day. Certainly much more frequent than with Ice Cream Sandwich (4.0.4).
Additionally, my battery life seems to be lower since the upgrade from 4.0.4. (It might be my imagination, but it might be running hotter than I remember, too.)
I've been looking for some common denominator but I'm baffled.
What can I do to try to find out what is causing these crashes?
(No suggestions that require rooting, please.)
