That's below freezing and usually out of bounds for operation. As to percent, I see nothing wrong with some variation here. Charge it up and as to age, since it's only a 300 cycle battery you can see loss in a year.
Have a refurb N4. I was out in the cold today for most of the morning with temps at around 3-5 degrees. This evening my phone died at 11%. Turned off, no warning. Is this a sign of a failing battery or as a result of exposure to the cold? Someone with me said their phone died at 17% in the cold but in the morning rather than in the evening.
Any ideas? I understand phone batteries die quickly over time but I haven't had the phone for long and this is the first time its happened (granted first time its run down to 11%)
Thanks
