I like it on top wrote:If I'm in an area where coverage is limited I put my phone on the airplane mode, which keeps it from searching for a signal and draining the battery. I also keep it in an inside, next to the body, pocket to help keep it warm.
YES, I forgot to mention that. You are absolutely correct!
So let’s review.
Put phone on Airplane mode
Turn off phone
Wrap phone with hand warmer in a sock and keep it next to your body for use when needed.
Another thing is get a GOOD battery- I know they can last for more than one year, but knowing that they really are only designed to last one year why chance it if you intend on using it for a emergency? New Battery$50- good, dead battery when needed- Bad
