“User experience is how users feel and think when they interact with, use, and remember the solutions that meet their needs. These solutions can be hardware- or software-based. User experience depends on both the physical senses (touch, hearing, smell, taste, and vision) and the mental states (energy, efficiency, interference, completion, and emotion) of the users.”

“There are two types of brain modes: low and high consumption. Low consumption modes are easy to remember and use less brain resources. Examples are muscle memory and conditioned reflexes. High consumption modes are hard to remember and use more brain resources. Examples are information processing, analysis, and judgment. These are two concepts that are clear in theory but vague in practice. The basic and underlying logic operations should follow the low consumption mode principle. That is why we should avoid double-side-interaction (in a normal mobile phone size).”

“Compartmentalization is a concept that means dividing or perceiving things as different and distinct. It affects how people react to things. For mobile phones, we can use different senses to classify compartmentalization. For example, visual, auditory, tactile, psychological, single, and integrated. For instance, the lock screen interface and the home screen in unlocked mode are different visual compartments. The home screen, the negative screen, and the App library are also different visual compartments on the same level. The top swipe, bottom swipe, left swipe, and right swipe on the home screen are different operation compartments on the same level. Single-finger clicks, single-finger swipes, and single-finger long press are different interaction compartments on the same level. There is a rule for compartmentalization: 1) The fewer items it can extend to the lower layer within the same compartment, the more precise and efficient it is. 2) To keep the low brain consumption mode, the upper and lower layer operations should not be more than three.”

“Apple has a consistent and exquisite concept of using the God curve in everything. The God curve is the curvature of the rounded corners that you can see in many places. For example, in the iPhone, you can see the God curve in the metal frame, the physical buttons, the rear bump, the camera, the receiver, the display, the Lighting connector, and even some internal components. In the software, you can see the God curve in the app icon, the dock, the search bar, the settings bar, the control center, the notification bar in notification center, the widget, and the notch (or dynamic island). The God curve is also present in other products, such as the Macbook and its software. And even in Apple's buildings and facilities, such as the Apple Park visitor center and its trash cans and seats. The God curve is a legacy of Mr. Jobs, who made sure that everything Apple does has a high level of consistency and elegance across hardware, software, product, and enterprise.”

“Color, the principle: First, you should think about how color affects the psychology of the user. Then, you should think about the role of color in the product. Finally, you should think about the color itself. According to the theory of static and dynamic, usually colors like static world, the new colors like dynamic elements, new colors will instantly become the focus while ordinary colors will not attract too much attention. For product design, you should aim for a continuous and integrated appearance of the elements, or avoid any interruptions or breaks. This includes the colors of the front panel, frame, and rear panel. For color itself, there are different levels of colors based on how often humans see them. The highest level color is the air, which is the most seen color by humans, but humans cannot make it. The closest thing to air is glass, which can create a 3D color effect by superimposing on other colors. This is a miracle that breaks the common sense that the eye can only see 2D colors. The second level color is the sky, which is the second most seen color by humans, especially during the day. The third level color is the human body, which is the most familiar color to humans, such as skin and hair. The fourth level color is nature, which is the second most familiar color to humans. The fifth level color is artificial. Monochrome is the cornerstone, and the color combination (the same color system can reduce the sense of abruptness, the near color secondary) and the gradient aesthetics are stricter. The more the style focuses on minimalism, the more it favors monochrome.”

“Line and shape, the best principles: Straight lines are the basic and simple form, while curves are more complex and beautiful. Curves can be inward or outward, depending on how they bend. Inward curves are more aggressive, while outward curves are more expansive. Outward curves are easier to handle than inward curves. Curve belongs to God, and is a kind of orderly cognition distilled from chaos, orderly in orderly will reflect each other, but orderly into disorderly in its will return to the basics of chaos or be weakened. Visual of a physical pure curve with a psychological straight line is the best, a curve-based straight line is the second best, a straight-based curve line is the third best, and a pure straight line is the fourth best. This is because a straight line is more harmful than a curve in a product. For example, the iPhone 14 Pro's flat frame is more uncomfortable to hold than the iPhone 15 Pro's round frame.”

“6. Material gloss, the principle: A non-mirror surface looks the same in any environment, but a mirror surface changes with the light and the surroundings. The same material can have different visual effects by using different processes and special materials. But it is hard to change the quality of the material by using the same process on different grades of the same material. Some materials have a charm that is not only based on their features, but also on how they interact with the environment. For example, precious metals can reflect light and show a unique visual effect, even if they are very similar to other elements. The best visual effect is when some of the light is reflected and some of it shows the gloss of the material. The second best is when there is no reflection at all. The third best is when there is a mirror-like reflection that creates complex scenes that are hard to control.”

“Consistency of the width of the four bezels, the principle: four bezels of equal width are best. The larger the difference between the maximum bezel width and the minimum bezel width, the worse the visual effect; the larger the difference between the bezel width of the adjacent border, the worse the visual effect.”

“Sound performance The sound quality depends on how well the codec can reproduce different recording situations. However, different people may hear the sound differently 1. Pitch, principles: The performance is better when the codec can restore different recording situations more accurately. 2. Loudness, principles: The performance is better when the codec can restore different recording situations more accurately.) 3. Tone color : ① Frequency range (principle: The codec can cover the range of frequencies that humans can hear, which is from 20 Hz to 20,000 Hz. ②Response time (principle: the shorter the better, excellent threshold is 10ms.) ③The spatial effect (The best codec is the one that can create a realistic sound effect without distorting or losing any specific frequencies. It should also have a balanced ratio of sound quality and compression.) 4. Sense of space, the principle: The codec should be able to reproduce the sound as if it is coming from different distances and directions in the recording studio. 5. Tuning style, the principle: The codec should be able to capture the details of the sound, such as the resolution, the atmosphere, the balance and connection of the three frequencies (bass, midrange, and treble), and the vocals and instruments. The codec should also be able to match the original recording as closely as possible. If the codec has a different tuning style from the original recording, it is not necessarily worse, but it should still be clear and pleasant. If the codec has a better tuning style than the original recording, it is even better.”

“The principle: The main components of a flagship device should be high-end, while other components can be mid-range or high-range, but not more than 30% of them. The device should not use low-end components that would affect its performance in some situations, especially those related to the core calculation and transport. Different companies have different abilities to negotiate with the suppliers, so the price does not reflect the quality of the materials used.”

“Let's do an experiment. Half a meter away from the screen, observe a lady's hand and a photo of the lady's hand through a mobile phone screen with 2K and 4K resolution respectively. We can feel a huge difference in the visualization of the three scenes, not only between 4K and the eye, but also between 2K and 4K. That is because in the microcosm (we imagine the lady's hand as a display), the smallest unit of the lady's hand is the skin cells, compared with the smallest unit of the screen display pixels, which differ by several orders of magnitude. This leads to the composition of the macrocosm being like a two-way street. That is to say, under the condition of not being affected by vision and distance factors, when the ppi is continuously increased to infinitely close to the smallest constituent unit of the surface of the object, its visual effect will continue to converge to the real object, but there will always be a certain difference from the real object.”

“Apple's iPhone A series chip has always been the strongest and most dominant in the mobile phone market, because Apple relies on this chip to lead the technology strategy. In the past, we did not care much about how powerful the A series chip was, but we felt that it could make the iPhone run very smoothly and efficiently in any situation. This means that the A series chip was always stronger than what the peak performance iPhone needed. However, this changed when the iPhone 11 series added the night mode feature. The A series chip could not handle the night mode processing fast enough, and it showed that it lacked enough computing power. This problem was not solved until the iPhone 14 pro series with the A16 chip.”

“Apple is losing its grip on the IOS and iPhone ecosystems. One example is the bad experience of IOS killing the background apps, which shows that Apple is not planning and controlling the IOS ecosystem well. Another example is the sudden increase in RAM for different iPhone models, which creates a lot of fragmentation and confusion for developers and users. It also makes the iPhone less efficient and reliable. I remember the days when the iPhone had 1G RAM, and it could keep the app content even after restarting. But those days are gone and it's not over yet.”

“The interaction with the phone: When you use the phone, you need to move your fingers to touch different parts of the screen. To make sure the phone does not slip or shake, you need to grip it harder. If you need to reach a far part of the screen, you need to push against the edge of the phone to stretch your finger. the smaller the thickness of the mobile phone, the easier it is to operate at a long-distance. These actions increase the pressure on your palm and fingers. The more you interact with the phone, the more uncomfortable your palm is.”

“Ads Management The principle: There should be no ads in the system and built-in apps that affect the user experience. The ads of third-party apps should not exceed the user’s tolerance limit, and try to maintain a consistent visual effect with the content in the app, and should not be presented in a separate form.”
