Charging your phone when it’s below 32 degrees can damage the battery. Warm up your device to room temperature up for at least 30 minutes before charging it. Get a thermal phone pouch, like one from PHOOZY or Salt, if you plan to be out in the cold frequently or for long periods.
When you call a dead phone does it ring?
Answer: A: With a dead battery it should not ring but it should go to voicemail directly.
