Help Battery voltage issue while charging?

[Aniro]

So I have had this message appear on my phone while charging, and apparently my charger can't keep up with the current that my phone uses. Is this something I can easily fix?

If it helps, my phone is using an extended battery.

i too have this phone. if its the charger that came with the phone. try a new battery. the charger should be 5volt 1amp

Happens to me every time I charge with the screen on.

I have this happen occasionally. I usually just stop using the phone for awhile when that happens and just let it charge.
