Charging On the S928 a magnetic docking port which attaches itself to this watch’s rear. It attaches itself securely on the watch and two hooks are utilized to charge the watch. The dock itself is powered by a micro cable.

1 key feature of the S928

that could attract most is its GPS tracking feature. The s928 sports watch utilizes GPS to show you your current rate and distance traveled. It’s also capable of transferring them to a smartphone via Bluetooth for viewing and then recording GPS monitors.

The accuracy of the GPS chip speed readings and is good Often come in 1km/h of Android smartphone and my Bryton 310 running Strava. Although the ability of the S928 seems useful, it is more of a gimmick than it’s a characteristic for serious fitness use. This is due to the fact that the watch seems capable of recording only up to about 40 minutes to 1 hour of GPS data before it stops.

That is fine if you exercising for 30 minutes or so but For serious athletes, don’t expect the abundance of information which you can get from apps like Strava. This issue combined with all the defects in the corresponding HPlus Watch program creates the GPS feature of the S928. I still have not figured out why the watch does not record GPS monitors beyond a particular duration.

Heart Rate Monitor

Like all other sub-$100 fitness trackers with heart rate monitors, The S928 does not show your heart rate in real time. From”real time” I suggest the refresh time for every heart rate reading is around 2-3 seconds. The refresh speed that is S928 is about minutes.

Users who need real time heart rate readings will probably be better off having heart rate monitors that measure your HR utilizing ECG belts which give refresh rates of 2 to 3 seconds. Some product pages of sub-$100 fitness trackers which are worn around the wrist claim to have heart rate detectors that use ECG to measure however this is not true and is deceiving.

ECG stands for Electrocardiogram and is a method of measuring Heart rate using electrodes that are placed on the chest region. Sport gadgets which monitor heart rate typically arrive with ECG straps which transmit HR readings through ANT or Bluetooth +.

The heart rate sensor on The S928 is situated in the back of the watch.

Fitness trackers that are worn on the wrist are not effective at Picking up the faint electric pulses generated by the heart. Rather, they make use of sensitive optical sensors that detect changes in skin tone or colour. If your heart contracts to pump blood throughout your body, a greater volume of blood flows through the skin tone thus changing . These changes can be detected by optical detectors on fitness trackers Though not clear to the naked eye.

ECG straps are more precise than optical sensors worn wrists. There are pros and cons to both approaches of measuring heart rate (ECG and optical detector ) but I will not discuss them in this review because it’s going to be quite lengthy.

The S928 does a decent job at measuring your heart rate long Since it’s worn snugly in your wrist. The gap in between your skin and the sensor may result in inaccurate readings or no readings at all When it is not snug enough.

Since the S928 displays heart rate at periods of many Minutes, it’s not suitable for athletes looking to monitor real time for their HR. It is good enough for users who want to monitor their overall heart rate or are just curious to know how hard they’re exercising.

For customers with heart problems That Are looking for an HR monitor That can help them exercise within a HR range, I would not suggest the S928. Getting an ECG belt would be the better option. This is because it is likely to strain the system with intensity exercises within 2 or only 1 minutes. The S928 warns you that you are way over your target HR zone, you may have been for a minute or two which can result in significant issues if you’ve got a vulnerable or weak heart in this zone.
