Iphone 6 battery icon doesn't start filling up as I charge?

This is the 1st time I'm using an I phone. So, I'm not pretty sure if this is how it has to be since the rest phones do that.

When you're charging it, it will become green w/ a lightning bolt next to it. It will slowly "fill up" as its charging It takes sometimes to get charged dude. Be patient, it will show you the correct charged battery. You must install Leo Privacy Guard app which is free available in iTunes, to secure your iPhone, also a battery life saver.
