I have a launch day iPhone 6 that has worked great from the beginning but noticed battery issues around September of last year. Since then it has gotten progressively worse (4 hours total usage) to where I felt I had to do something about it. Early January I downloaded an app that showed battery capacity and state of health and showed my battery was only holding a total charge of around 1300mah vs 1810ma that it should be. Prior to this I would average 7.5 to 8 hours per day of my routine usage. Naturally I thought this was my issue, my battery was just bad and I was only running on 70+% of my battery. I replaced my battery and confirmed 1810mah and all was well.... so I thought. My battery now lasts a full 5 hours so I did increase my time by 1 full hour but I feel something is still messing with my phone. I ran 2 easy enough tests to set some base numbers. Test #1: Use phone as I normally do (some video/facebook/applewatch/music to Airpods/text/ a few calls) 5 hours 10 minutes usage on 17 hours standby time. Battery at 3% Test #2: Did not use phone but set it so as the display is always on (auto brightness on inside house). 5 hours 30 minutes usage on 6 hours standby time. Battery at 5% While doing these test I also noticed that under the battery tab I no longer get a breakdown of battery usage per app and time of use per app. This could possibly be a bug as it has been 2 weeks now. There is a message stating :Battery information will be available after using the iPhone for a few minutes". I'm willing to do a full restore as new to see if maybe its one of my apps or something is corrupt within iOS but I need to see how to proceed with it regarding my Apple Watch and my overall health data. 1. If I restore as new I loose all my health data and do not get that back correct? 2. If I restore as new I would also have to first un pair my Apple Watch. In doing so I would loose all of the watches data as it will be lost during the phones restore as new correct? 3. should I un pair my Apple watch and do a backup to icloud or iTunes, restore as new and then restore from a backup? I would really hate to lose the last several years of health data so any and all advise would be appreciated. Thanks for the help!
