My iPhone battery goes down even though it says it's charging?

I'm noticing today that my charger isn't the same. It's always worked before but now when I plug it in, I see the little charging symbol on the corner, but the battery percentage goes down slowly. My charger is designed so that when my phone is plugged in, a red line goes on. Now the light is turning on and off, but the charge symbol remains no matter what. I have to stay at a certain position for the light to stay.

What's this for and why does it happen?

Ok so when I'm using my phone I'll have my data on and I'll have like 4G or 3G whichever one I can get and then out of nowhere my thing will switch to an "E" and then when it's at an E nothing loads. So what does the E even mean and what's it for? Like why is It there and why won't anything load when it does that? I have an iPhone btw

Go SMS Pro sending messages over Wi-Fi?

I've tried to read up about Go SMS Pro because I'm going to be switching from an iPhone 4S to a Galaxy S5 tomorrow and I want to find a texting application that I will be able to use to send messages not only using my regular messages when I'm out, but also when I'm on Wi-Fi I wanna be able to send them on that as well like you would if you had iMessage! Now it doesn't have to be like iMessage but my girlfriend just got her iPhone 5C but I decided I didn't want an iPhone this time but a Galaxy, so we won't have iMessages anymore. But if I'm somewhere without service, but with Wi-Fi I wanna still be able to message her on the same application with my phone number! Can Go SMS Pro do that? Or are there any other apps out there that can?
