Because these two models have many key features, including design, water resistance and optical heart sensors, it may not be easy to decide which model is more suitable for you. Is it worth buying a cheaper model with fewer features? Our guide answers the question of how to determine which of the two apple watch models is best for you. < / P > < p > most of the features of the two models of Apple watch are identical. Apple lists these same features of two models: < / P > < p > ltpo OLED display with a shell size of 44mm or 40mm, a brightness of 1, 000 nit GPS and GPS + cellular model 64 bit dual core processor W3 wireless chip digital with tactile feedback Crown optical heart sensor, high and low heart rate and irregular heart rate, informs international emergency call, emergency SOS and fall detection, noise monitoring, waterproof depth up to 50 meters; “swimming” WiFi and Bluetooth 5.0 support home setting compass and forever online hour “all day” battery life apple subdivision display, these two models have the vast majority of functions. Even so, there are still a few significant differences between Apple watch series 6 and apple watch se, such as ECG and blood oxygen monitoring. Differential Apple watch series 6 < / P > < p > U1 ultra wideband chip blood oxygen application ECG program blood oxygen sensor; electronic heart sensor and second generation optical heart sensor extend the battery life of some exercises, speed up the charging speed new colors: blue and red apple watch se < / P > < p > only optical heart sensor continue to read, in order to understand each of these aspects carefully And see what the two latest Apple watch models offer. Displays Apple watch series 6 and apple watch se are equipped with retina ltpo OLED displays with a brightness of 1000 nits. The key difference, however, is that series 6 has a always on display. This means that even if you put down your wrist, the display will remain on, so you can always see the dial without lifting your wrist correctly. < / P > < p > when the user’s wrist is down, the brightness of the apple watch series 6 always on display is two and a half times higher than that of the outdoor Apple watch series 5, making it easier to watch the dial in bright sunlight. When the wrist is down, users can now also access the notification center and control center, tap complexity, and swipe to change faces without having to wake up the watch screen. < / P > < p > Apple watch se does not have a screen that is always displayed, which means users have to lift their wrists or tap the display to see their dial. < / P > < p > in addition to this function, the high-resolution retina display itself is the same between the two models. Unless you have a special need to always look at the dial without lifting your wrist, the display of Apple watch se will be enough to meet your needs. < / P > < p > when it debuted in Apple watch series 5, it was already a powerful processor, while S6 only provided a more sophisticated chip. Unless you absolutely need the fastest application startup speed, the small performance improvement of S6 chip does not seem to be enough to justify that Apple watch series 6 is superior to Apple watch se. For the vast majority of users, apple watch SE’s processor will have the right speed and efficiency. < / P > < p > only apple watch series 6 contains U1 ultra wideband chips. Apple said the U1 on the apple watch would “enable short-range wireless locations to support new experiences, such as the next generation of digital car keys,” but it was unclear what else the chip could offer. < / P > < p > by calculating the time of radio wave passing between two devices, the distance between two devices supporting UWB can be accurately measured, and its accuracy is much higher than that of Bluetooth le and Wi Fi. < / P > < p > although apple is increasingly implementing the chip on its new devices, it has yet to unlock a large number of new features. So far, Apple has only used this technology to support the directional airdrop function in IOS 13, but it recommends more exciting use cases in the future. This indicates that the U1 features on Apple watch series 6 may be extended. < / P > < p > because U1 chip currently has only a few use cases, it is not worth getting Apple watch series 6 just because of it. However, if you plan to keep the apple watch for many years, the U1 chip may make it a more forward-looking model because it is likely to use more features in the next few years. < / P > < p > Apple watch series 6 provides blood oxygen monitoring; a new health monitoring function has never been seen on Apple watch. This function measures oxygen saturation in the user’s blood, so they can have a better understanding of their overall health. Oxygen saturation, also known as SpO2, represents the percentage of oxygen carried by red blood cells from the lungs to other parts of the body, and represents the delivery of this oxygenated blood throughout the body. < / P > < p > there is a blood oxygen sensor in the rear of the watch series 6, which consists of four clusters of green, red and infrared LEDs. They measure the light reflected from the blood and, using an advanced custom algorithm, can determine 70% to 100% of blood oxygen saturation. < / P > < p > the blood oxygen application can be used for on-demand measurement and regular background measurement, including during sleep. All data is visible in the health app, and users can track trends over time to see how their blood oxygen levels change. < / P > < p > in addition, apple watch series 6 includes previous models of electronic heart sensors for ECG or ECG acquisition. Apple watch series 6 has built-in electrodes in digital crown and an electronic heart rate sensor at the back. Using the ECG application, the user touches the “digital crown” and receives the heart rate rating 30 seconds later. It can classify whether the heart is beating normally or whether there are signs of atrial fibrillation, a heart disease that can lead to serious health complications. All records, their relevant classifications, and any noted symptoms are stored in PDF format in the health app and can be shared with doctors. < / P > < p > Apple watch se does not have blood oxygen or cardiac electrical sensors to monitor these two health statistics. However, apple watch se is not incapable of recording any health data. < / P > < p > other health monitoring features of Apple watch series 6 are the main attraction of more expensive models. If you think ECG and blood oxygen monitoring are important to you, you should consider using apple watch series 6. If these advanced health features are not so important to you, apple watch se still has some in-depth health monitoring features. < / P > < p > however, apple watch series 6 offers faster charging speed, can complete a full charge in an hour and a half, and can extend battery life to track certain exercises, such as indoor and outdoor running. Series 6 has also been optimized so that it is theoretically unaffected by its consistent display. < / P > < p > since the battery life of the two models is actually the same, series 6 may not be recommended only on the basis of faster charging speed and slightly improved battery usage during specific activities. Instead, the battery and charging enhancements of series 6 remain an important indication of how the device can make a series of subtle but meaningful improvements over the apple watch se. < / P > < p > Apple watch series 6 offers aluminum, stainless steel or titanium, while Apple watch se offers aluminum only. Apple watches with stainless steel or titanium also use sapphire crystal screens, while aluminum watches use ion-X reinforced glass. < / P > < p > the aluminum Apple watch series 6 comes in silver, dark grey, gold, blue or red. Stainless steel has silver, graphite or gold, titanium has titanium or space black. Apple watch se is only available in silver, dark grey or gold. < / P > < p > if you prefer stainless steel, titanium or blue, red, graphite, titanium or dark black finish, you should choose apple watch series 6 as it is the only model that offers these materials and colors. But if you’re satisfied with a lightweight aluminum case with a basic silver, dark grey or gold finish, the apple watch se is enough. < / P > < p > Apple also offers the apple watch series 3 for $199. Older models offer significantly fewer features and smaller screens. The apple watch series 3 is still a powerful device with 8GB of storage capacity, 50m of water resistance, altimeter, emergency SOS and optical heart sensor. In terms of function, it is more cost-effective than apple watch se, with larger borders and thicker thickness. < / P > < p > Apple watch series 6 is a great improvement on the previous series 5 models, providing new features such as blood oxygen monitoring, S6 and U1 chips, and always on altimeter. Apple watch series 6, with its always online display, advanced health monitoring features, and a variety of colors and surface treatments, will be the first choice for those who need its wearable devices most. If you’re particularly interested in health tracking, or just like special case and color combinations, apple watch series 6 will be your best choice. < / P > < p > in addition, if you have a limited budget and are not particularly interested in other features of series 6, apple watch se is a very attractive choice. Apple watch se will become the preferred model for many apple watch customers, especially those who are not familiar with the device. < / P > < p > Apple watch se is probably the most popular of the two, so it will be the default choice for most potential customers. Because it has many features with apple watch series 6, you should choose the more expensive model only if you value other features or advanced health monitoring and can prove the increased cost. 15 entry-level basic skin care rules, skin care Xiaobai quickly take to collect!
