Well...I made an account just to say thank you.
Just moved apartments this past weekend and have been relying on my phone for internet. Also just dished out some money to upgrade my data for the wifi lull at my apartment.
Then.... I wake up after charging my iPhone5 all night with nothing but a low battery symbol
So I'm sitting here in a coffee shop and I come across VFRWiz's post and I get excited by the prospect of not having to go buy a new phone/replace my battery RIGHT AWAY.
I'm naturally skeptical so I decided to read through the whole thread before I was on board, especially given the warnings. Since after reading his or her comment, it did occur to me that my phone (and my new apartment) were a little bit colder than I'm used to, before I read through the rest of the comments I decided I would sit on my phone. Not directly on top of it, I just put it under my leg.
10 minutes later I took it out and plugged it in immediately and....it WORKS.
No hair dryer. No heat gun. Same principle. Good thing too because I don't have a hair dryer or a heat gun.
THANK YOU VFRWiz.
PS: I am not advocating the use of any heat generating equipment on your electronic devices. Just give 'em a cuddle for like 20 min and maybe that will help.
