For some reason my battery life is draining fast and charging takes forever. When I got to work my battery was at 100%, that was about 5 hours ago. I haven't used my phone at all except for one, 2 minute phone call and the battery is now at 47%?? What is up with that?? Also, I noticed last night it took forever to charge (I have a wireless charger and have the phone set up for fast charge - or whatever it is called). Any thoughts? TIA!
