Just bought my first iPhone and have several questions:

Suggestions for charging battery...been told that charging with Mac not best method? same comment about charging with car cigarette lighter?

Then, someone recommended shutting down the iPhone periodically? Is this true? How often? How do it?

Thanks for helping a newby on iPhone.

I'm not sure if it makes a difference where the power is coming from. They're all suppling the same voltage and amperage AFAIK

Apple's recommendations for battery life.

Peter Baer Galvin , of BYTE also has an article.

Amperage is irrelevant, as long as sufficiently provided.
Any electrical device will only draw as much as it needs.

You received some bad advice. There is also no need to periodically shut down the phone.

Only if something freezes, which happened to me twice since 10/14/11. You hold the top right button down until a screen appears, follow instructions. Turn back on using same button, holding it until a white Apple logo appears, then wait...............
