Hard to say as it depends on the battery and how good it is. A good battery can sit for 6 months and easily still start a car and 1 year is not out of the question.
Every cell phone is different when it comes to how long the battery will last. If your phone is fully charged it should last at least twelve hours. If you frequently get emails and text it may be a little less.
battery is low charge. Take it for a long drive, to take the load off the engine from the alternator charging it.
Charge and check your battery. Charging systems in these bikes are notoriously not amazing. Nighthawks have electronic ignitions which controls idle speed automatically. I.e. if the battery power isn't there, theres no idle = bike dies. Might want to look into a new voltage regulator if problem is persistant. Or, just use a battery tender frequently. Hope that helps.

You didn't say what year it is but earlier models also had an external voltage regulator that could fail. I would drive it to an auto parts store and let them test the charging system. They will do this service at no cost.
The life of the battery. You never have to change it.
usually no longer than 15 minutes
You may be tempted to buy an extra mobile battery when you get your phone, but you should not do this unless the one that you have dies. Many times, the batteries will not die before the contact expires and you get a new battery anyway. The extra one would just be a waste of money. You should always wait to see if yours will last long enough before you buy an extra one.
Assuming the car is a gas powered vehicle, and not a diesel the answer is, just long enough to get all the snow off the windshield. You don't need to let the car idle before driving it. The only reason to let it idle before driving is to defrost/defog the windows.
As long as the battery is charged and electrical component use is kept at a minimum I've seen vehicles drive for a couple of hours before the battery dies. Newer cars with daytime running lights and lots of electrical toys die quicker.
The amount of time between now and their death.
i think it is 5 days
