Sirmaru, I'm talking about charging Kindle Fire HD 8.9 16/32Gb in temperature
range 58F-50F. Winter is comming
As I said before - left device in the compartment with temperature below 59F, wait for 2 hours and start charging. In 3-4 hours the battery stop charging
at 70% (plus/minus 2%).
According a specification you found for Kindle HD operating temperature range it's not looks like by design. Bummer.. it's a design flaw.
