I realize this topic was first opened way back in October but I'm wondering if people are still experiencing issues? I've had my new iPhone 7 for a few months and it has been horrible when it comes to battery life. AppleCare support was absolutely useless for the first few contact attempts. They told me that logs show my phone is operating as it should. The problem is that it loses 1-3% of battery every hour without use. I'm a very light user and don't use any form of social media. I text and even that usage is generally less than 600 messages per month. I also make/receive an average of about 8 calls per week. There are many days that my phone just sits on the desk for 8-10 hours before I even touch it. The phone is currently at 17% and less than 24 hours ago it was at 100%. I received a five minute phone call last night and that is all. All apps are closed and background app refresh has been turned off for nearly every app. I also don't allow notifications from apps other than a few of the built-in ones.
About four weeks ago, I finally got through to someone within Apple support and they started looking into the problem a little more seriously. During our testing, I decided to just turn the phone off one evening out of frustration. It was fully charged at 100%. When I turned it on the next day, it was down to 86%. I've been able to duplicate this problem repeatedly. Apple had me run a sys diagnose and send to them. Engineering reported back that the phone logs are showing that it is being turned on even though it was turned off. They basically accused me of not knowing the difference between sleeping and physically being turned off.
I have a continuing case regarding this problem but I'm starting to get annoyed because I've seen a few other posts where people have had similar problems and they had their phones swapped. Apple is refusing to do that for me. When it started, I stated that it wouldn't make sense to just swap it until we had some better idea of the problem but we are well past that now. In the time it took me to write these three paragraphs, the phone has dropped to 16%. For the record, I'm typing on my MacBook Pro and the phone is sitting on the desk. I started making videos of the battery issues as I feel like Apple is acting like I'm just making this all up. I'm beyond annoyed at this point but I've been an Apple user for over 15 years. It's hard to switch but with support like this... So is anyone else still experiencing these problems? Any suggestions for documenting the issues with irrefutable proof? Thanks.
