Hi guys, finally posting a thread here because I'm at my wits end right now and want to see if anybody else has any ideas before I drive the two hours to an Apple Store. Last week I started seeing a big decrease in my iPhone 6S Plus battery life. Basically it was dying within 10 hours of taking it off the charger. Checking my usage, I noticed my usage and standby time we're always equal. I don't use background app refresh, location services, or anything that would constantly be on in the background, so I figured I'd watch it. Next day, same problem. That's when I decided to restore my phone with the IPSW and then restore from backup. Yep, same problem. I could not figure out what could be causing the problem until 6 hours into my work shift my Apple Watch gave me the 10% battery warning. I thought that was weird as I've had the watch since launch day and it has never died before. So I went into the Apple Watch app and noticed my usage time and standby time for the Aple Watch was basically the same. 6 hours of usage, 6 hours and 14 minutes standby and 10% battery left. Went home that day and reset the watch by holding the crown and other button figuring I had a rogue process in the background. Watch was off on the charger and my iPhone was not draining quite as quickly nor was my usage/standby time the same. Great, isolated the problem to the Apple Watch. Well, next day same thing. Watch is nearly dead half way through my work shift and iPhone is draining and usage/standby are nearly equal. To let the watch live, I turned Bluetooth off on my phone so the watch wasn't connected. The 10% battery lasted nearly 3 hours after I turned Bluetooth off on my iPhone and the phone stopped draining. So I went home and figured, unpair the watch and see how that goes. Tried to unpair and restore from backup. When I hit 90% in 30 minutes I knew it wasn't fixed. Next step: unpair watch and set up as new watch. Install no apps, basically leave it at factory settings after its set up as new. And here I am typing this as an hour into the watch being set up as new with nothing installed it's at 82%. Usage is at 58 minutes and standby is 1 hour and 1 minute. I truly don't understand how setting it up as new and having done nothing on it I am still having this problem. I do not believe it's a battery issue, there's something going on though and was hoping someone else had some ideas. Also, I do not use any 3rd party apps on the watch, I've never had them installed even before setting it up as new an hour ago. So it's not a 3rd party app issue. The only other thing I can possibly think to do right now is set my iPhone up as new and see if that fixes it, which I was trying to avoid but I don't know if I can any longer. Anyone have any ideas?
