I have a 2 month-old iPhone 3GS and love it, but was wondering if exposure to cold weather affects battery life. I can't get a license because of my vision and literally have to walk everywhere. There's no public transportation or taxis here and the neighbors won't ever give me rides, so I walk two miles or more every day in all kinds of weather. I have no choice. When I left the house yesterday my battery was at 100% and when I came home, after being out for about 2 hours with my phone in my pocket and not using it at all when I was out my battery was at 89%. I was wondering if the cold weather had caused that? I was out for 2 hours on Tuesday when it was even colder but I had a hoodie on under a ski parka that covered the pocket where I had my iPhone and the battery was okay when I got home. So I wonder if it was because the jacket I wore yesterday didn't cover the pocket where the iPhone was and it got cold? I will make sure to wear my ski parka from now on this winter. Has anyone else had this problem? Thanks for any help or suggestions on this!
It is possible that the cold temps kill batteries. When I used to leave my phone in my car for a few hrs. it would make my phone/battery act funny/drain batt. If you can't read this (vision problems you stated) have somebody read it to you.
The cold will affect battery duration. But, in addition to that, we have to ask, what's your brightness on the device set to? If over 35-40%, it will cause the battery to die quicker.
Wifi, is it on, and not needed? Bluetooth, etc, etc...
yup I would agree with naviwilliams. if you reach a dead zone the phone will be in searching mode therefore killing more battery life. and this goes for wifi also.
