[Android Central Question]

My LG stylus 3 is taking too long to fully charge. I try to put in on wall charger the whole night. It doesnt fully charge. Please help me

Welcome to Android Central! Is this the original charger? How high does it charge to? Do you still get normal overall battery life for a single charge?
