I noticed all of a sudden that when I plug my fast charger into the phone, it no longer says "Fast Charging xx%" on the home screen it just says "Charging xx%". And, of course, it takes longer to charge the phone now. Does this mean my battery is dying or is there a setting I've turned off inadvertently. I have several fast chargers (wall and car) and the above is true no matter which one I use, so it's not the charger.
