I took advantage of the $29 battery replacement in mid September for my 6s running 10.2, and I specifically asked if they needed to update the IOS. Was told it wasn’t necessary and proceeded with the replacement.

Right, but now their diag software requires a minimum of 10.3. So, if you're on a lower version (such as iOS 9.0.2 for me) you're going to get updated and lose your jailbreak.
