My iphone 4s automatically reboots itself when it gets too cold why is this?

I would like to know if there's a solution to this issue.

How cold is it getting? Why is it getting so cold?

It may be a weakening battery. (Just a guess.) You know-- how when your car's battery starts to get old, it is going to give out on the coldest morning in the middle of January? Same principle.

  • Why does my Iphone lose battery in cold weather? I have an Iphone 5 and i usually keep it charging, but when it's like on 70% and i'm outside in 15-40 degree weather, all of a sudden it says that I only have 20% left, than about 1 minute later it says I have 10% left and than 20 seconds later, it dies. This has happened around 5 times and my question is why does my phone do this? And how can I fix it so it doesn't happen anymore?
  • Why does my iPhone 5c home button not work in the cold? I just got this brand new iPhone 5c from Verizon store I work downtown out in the cold by the water so it's always like 20 degrees out and the home button always freezes and becomes unresponsive then goes back to normal on my way home not exactly what I want out of the "best phone"
  • Why do I feel sleepy and weak? And my temperature changed from cold to hot? When I was sleeping last night I switched on my AC next to my bed, and first I felt cold then hot… I was wearing long trousers but short sleeved shirt. I'm at school now and its difficult for me to walk I feel so weak! This morning I didn't feel like eating as well. I didn't finish all my breakfast just left a bit of cereal on my bowl. Now I don't feel so good, feeling dizzy a bit, I was using my iPhone before going to bed, got a bit of sore throat and cough too?!
  • My iPhone 4s' brightness is turning itself low by itself? - 1 How do I fix this? Is it a bug? I have the iOS 6.1.3 installed. I did drop it in water like 2 weeks ago but I made sure all the water came out, my step mom dropped her phone in the toilet like a year ago and till this day it works perfectly fine! So why is mine having problems?
