Chris, Not sure about #1 but I do applaud your generosity in sharing ideas.
You assert that connecting the phone to ac mains at 13 Amps vs. USB at 1/2 Amp helps to keep your battery healthy. Based on my EE studies, the amount of current (Amps) available to a device does not mean that the device is consuming or having to cope with all that current. The amount of charging current going to a battery is dictated by the charging device (USB or a wall-wart) and each are designed with current-limiting circuitry. This is dictated by Ohm's Law E=IR. The amount of current delivered to a battery is a function of the amount of voltage and the effective resistance in the circuit handling that voltage. Simply put, even if ac mains looks like a 3-inch diameter water hose, ready to drench your flowers with water coming in at a rate of 20 gallons per minute, attaching a 1/4-inch hose to the end of it will restrict the total volume of water that can flow to a much smaller amount, such as 20 Fl Oz per minute. Water flowing through a hose is the same principle as electrical current, which is coulombs per second. So unless your wall-wart is defective and delivers a short-circuit to allow 120 (or 220) Vac to directly couple to your phone,you won't get more than the recommended amount of current delivered to the battery.

I admit to my somewhat incorrect wording of the recommendation. I mean any applications that are running in the background can drain battery power very quickly. This could include Joikuspot Lite, a program to allow your phone to act as a wireless hotspot, and so on. Sorry about that. Yes, it's the application that are *running*, not just installed. Take care. Chris Hallsworth On 17/03/2011 21:19, Stephen Giggar wrote: > Number 2 doesn't make any since at all!
