I'm curious to see what others' 6 Pluses have reported as the full charge capacity for the battery. You can use a tool called iBackupBot then click "More Information" on your device's page. Here's mine:

I'm guessing that this tool isn't accurate since I'm getting a larger capacity then it was designed for. Also, I thought the the design capacity was 2915 mAh. Then again, batteries aren't perfectly built to spec.
