I've noticed whenever I'm charging my iPhone 5S and I go to touch the home button, sometimes it gives me a little static electricity shock. It's happened a few various times when I've touched the charger (plug in to phone part) while unhooked. Also, if I touch the screen, it occasionally gives me a shock too. The phone is in an otterbox, if that makes any difference.

Of course, I always have a lot of static electricity lately and all. So is more a matter of me, or the phone? And it only happens when charging.

Is this normal?

That would do it. The iPhone can't prevent static for you. Touch something else to discharge first if this is a problem. Increasing humidity may help to reduce the generation of static electricity.

It happens when charging because the voltage is able to jump to ground via the power cord. My house is extremely dry in the winter and I'm always zapping stuff. I'm surprised I haven't killed anything electronic yet. I do try to touch a metal object before picking up my laptop or unplug my charging phone.
