iphone shuts down panic.ips very difficult to restart using home and power buttons
My iPhone 5 is about 1-1/2 years old. Yesterday the phone shut down during a voice call and would not restart even when pressing and holding down the power buttons simultaneously for an extended period of time (+ 10 seconds). After about 30 minutes I tried the dual button reset and was able to get the phone to restart. I plugged it into my MacBook and got an error saying the phone was in recovery mode. Since the first shutdown event I have had 6 more shutdowns, I have been able to reset with varying amounts of wait time and attempts. This morning the phone was dead again, I reset and checked the diagnostic & usage data. There are 9 panic.ips crash logs beginning on 6-04-2014 at 4:44pm.
The preceding error code to the .panic.ips codes was: awdd_2013-05-15-1.consolidate
It appears that something is wrong and that a simple reset is not able to clear.
What if anything can I do short of taking the phone to the Apple store?
Thank you,
Rick
