In terms of appearance, the biggest upgrade of the S7 is the screen, the use of ultra-low power LTPO OLED technology, coupled with Apple specifically designed for battery life optimization of the dial, so that we do not lift the wrist in daily use, but also do not have much impact on the battery life.
In addition, the screen border of S7 is narrowed by 40%, which is nearly 20% larger than the screen area of SE. Coupled with the full keyboard input method specially designed by Apple for S7, we can get a better keyboard and handwriting input experience than SE in daily use, but in actual use, we still prefer to complete the input by voice.
In terms of battery life, both watches are about 18 hours, but the S7 charging speed is nearly 33% faster than the SE, 45 minutes of time can probably charge the watch to 80%, if you need to wear it at night, you only need to charge 8 minutes to detect 8 hours of sleep quality.
In addition, the S7 has two more sensors than the SE, which are electrode heart rate sensors that can improve the accuracy of heart rate detection, and blood oxygen sensors that can detect blood oxygen concentration. It can determine whether the body is healthy by measuring the blood oxygen saturation of the human artery. For users who are more concerned about the heart and lung health or like outdoor mountaineering, they can understand their own physical conditions at any time through the blood oxygen APP, which is very useful.
To sum up, although the difference between S7 and SE is not big in daily use, S7 adds more sensors to improve its ability to monitor our health, so if you are more interested in this aspect, then you can start S7, if you just want to get news reminders, monitoring sleep and other routine functions, Then saving a few hundred dollars to start an SE is enough.
