6S+,my error. Before they took it in for battery replacement,they ran the diagnosis and found no issues. I knew the battery was at 89% and it was verified and I was told it had only 177 charging cycles since new. The tech said when the charging cycles go higher than 1,000,the battery starts to deteriorate so I was in great shape there. My phone was flawless on the outside also. They said return in an hour and it would be ready. I return and had to wait about 10 minutes and as the tech appears,I see he has a box in his hand.Not a good sign. They had somehow broken the camera and I received a replacement with a 90 day warranty. I'm fine with that. And I verified the new battery shows 100%,so I may wait another year to replace it with an XR. Kudos to Apple.
