Does the Magnet on my iPhone5 Cover empty my battery?

There is never a lot of apps running in the background. I do not understand "or you are over-charging your accsessory". I know of no accessory which is charged by the iPhone.

Magnets have no adverse affect on the life-span of batteries, they can neither drain nor charge an iPhone battery.

You might find that a lot of the time you have a lot of apps running in the background or you are over-charging your accsessory, which will drain the battery life.

I'd say there are Accessories which are charged by the iphone

the ligthingbolt to hdmi adaptor was taken apart and shown to have a arm cpu inside the connector

so that cpu would be charged by the ligthingbolt connector

What I meant by "over-charging the accessory" is are you charging your phone for long periods of time, because if you are, this kills the battery resulting in it dying faster than usual and you having to buy a replacement battery.

The iPhone does not have the ability to switch off the supply, and you can over-charge any appliance which uses a battery that stores charge, this includes iPhones. The same thing happens with laptops, people charge them for too long and about a year down the line, the battery needs replacing.

Sorry Rudegar. You cannot charge a cpu. You can provide power to it to enable it to function, but it has no means of storing a charge.

it's pretty common knowledge that all IC (Integrated circuit) chips have capacitors connected to their power supply to provide them with a stable current so you "charge" all chips in all devices

No, the magnet is not responsible. Magnets don't extend the life of batteries either. It doesn't work either way.

covers which extend the batt life if they work does so because there is another battery build into the case which connects to the iphone connector and charge the internal batt

Sorry Rudegar. You cannot charge a cpu. You can provide power to it to enable it to function, but it has no means of storing a charge.

The iPhone simply switches off the supply when it is charged. It cannot be overcharged.

Wrong. You cannot overcharge an iPhone. This has been discussed ad nauseum on these boards. You are apparently still living in the age of NiCad batteries.
