    Id say there's nothing wrong with that. Batteries will degrade overtime. The batteries nearly a year old I guess. Make sure you've done the battery update.

    Batteries are rated to survive 300 cycles. 73% health after 113 is not bad, really. Sounds like a normal wear-and-tear situation. Some people will have better, some will have much worse. Calibration generally doesn't improve your health % by any significant amount, and may artificially decrease the % (not actually make it less healthy, just give you a more accurate health %)

    If you are having issues with battery life, you can consider contacting Apple. If battery performance is significantly sub-par prior to that 300 cycle count, they may replace it, but it's subjective on their end so they may not. If you aren't noticing an issue, then don't let a health % bother you.
