Considering I need my phone for work, this means 2-3 charges PER DAY on a brand new legit samsung battery. Like I'm talking I was only getting 2-3 hours with usage of about an hour in that time before I hit below 15% from 100%.

I spent the last few hours trying to figure out why my brand new battery was draining just as quick as my old one.
