官方论坛 11 月 10 号放出消息，放出 Fitbit Charge HR 固件更新版本18.102，以下是官网给出的介绍：
This release provides the following new features and improvements:
- SmartTrack™ is now available to automatically track your exercise.
- We’ve enhanced our PurePulse™ heart-rate technology. Now when you activate exercise mode, you’ll have even better heart-rate tracking during certain high-intensity workouts like Zumba® or bootcamp classes.
- Quick View is improved.
- Step data is now counted towards challenges even when your tracker has very low battery.
It also provides minor bug and security fixes.
这次更新，优化了快速查看功能，优化了心率检测算法，还可以自动根据所进行的运动来调整。也强化了低电量情况下计步性能，电池容量就那么些了，低电量还能更好的使用这个还是挺不错的。另外，就是修补了一下 Bug，手机通知隐私问题也有强化。比起上一次 Fitbit Charge HR固件更新版本18.84 来说，更新力度不大，但是已经很完美了，在很高层次上之后，每一点进步都很难、很小。
