battery dies to quickly

I recently changed the battery on my iPhone 5s because the old one would die quickly so I put a new one in and I'm still having the same issue. Last night I left it fully charged and when I woke up 6 hours later the phone was completely dead.

Answer this question I have this problem too

Is this a good question?

If you use an aftermarket charger, sounds like the U2 IC on your iPhones main board is fried. Google IPhone 5s U2 IC to see more.
