I purchased the iPhone 7 on launch day through the Jump on Demand program at T-Mobile. I quickly discovered that the phone would lose 2 percent per hour in standby mode. Everything else about the battery was OK except for that. I would charge the phone to 100 percent before bedtime and wake up 8-9 hours later with the battery percentage down to 82-84 percent. Just before the 2 week return period was up, I decided to go back to the 6S where I didn't have this issue. Last week however I got the itch to go with the iPhone 7 again and pulled the trigger. I'm having the same exact issue however again. I contacted Apple Support on the phone tonight and they tested the battery and found it to be in perfect condition. I figured that was gonna happen. I still have a genius bar appointment next week that I'll go to but I doubt they will exchange the phone. So my dilemma is do I just live with this and hope that a software update down the road will fix the issue or do I just go back to the 6S and wait for the iPhone 8? I'm just curious how many of you could live with this issue. I mean I could put the phone in airplane mode overnight and the battery would stay at 100 percent. But who really wants to have to do that? Thoughts?
