Answer:
Answer:

Understand that the temperature that you state is at the very bottom of the operating temperature recommendation. That could explain the issue. Lithium-ion batteries exhibit problems in cold weather. That is a trait of the battery chemistry. Try keeping the device in an inside pocket and protect it from the cold.

You are not addressing Apple here, this is a user to user support forum, and Apple doesn't participate. You are the one that needs to fix your device. You need to troubleshoot the problems and fix them. When you say discharge in cold weather, I'm hoping you are keeping the phone within the recommended temperature range. Other issues are handled differently. You need to describe the problems.
