In terms of appearance, the biggest upgrade of the S7 is the screen, which adopts the ultra-low-power LTPO OLED technology, coupled with Apple's specially designed dials for battery life optimization, so that even if we don't lift our wrists in our daily use, we can also do the screen is always on and does not have much impact on the battery life above. In addition, the S7 has two more sensors than the SE, namely the electrode heart rate sensor that can improve the accuracy of heart rate detection, and the blood oxygen sensor that can detect blood oxygen concentration. It can determine whether the body is healthy or not by measuring the arterial oxygen saturation, which is very useful for users who are more concerned about their cardiorespiratory health or like outdoor hiking sports, they can always use the Blood Oxygen App to understand their own physical condition.
In summary, although the S7 and SE in the daily use of the difference is not great, but the S7 because of the addition of more sensors, to enhance its ability to monitor our health, so if you are more interested in this aspect of the words, then you can get S7, if you just want to get the daily news reminders, sleep monitoring and other conventional functions, then save a few hundred dollars to get SE is also enough.
