    It now lasts between 4-6 hours per charge ? I don't get it...Why would that randomly happen? I haven't downloaded any new apps either.

    Check what you got running in the background.
    Turn it off with power switch and restart it.
    BE REALLY SURE THAT THERE IS NO BATTERY INTENSIVE STUFF RUNNING IN THE BACGROUND
    If this won't seem to help,return it,you have a warranty.

    Good advice from Stefan. I had the same problem with my almost new 7+ and Apple advised me to reset and restore from backup to see which app was sucking up my battery. I found out the "HiYa" telephone app was using my battery like a thirsty camel drinking water in the Sahara. I removed that app and now my 7+ battery will last for 3 days in between charges.

    Also screen brightness is a killer too. Amazing how much longer the battery will last when you lower the brightness.

    For me, I can't even have the brightness up that much, being how radiant the display is. Unless I'm in direct sunlight where I need it, I usually keep the brightness at half or less.
