Do you want to use your phone for a long time? Maintain the battery first             What is the health level of your mobile phone battery now? Do you need to carry a charger with you at all times when you go out to play? Are you troubled by the fact that your mobile phone consumes a lot of power?Regarding this solution, I believe everyone’s first reaction is to replace the battery. However, when it comes to battery replacement, some people say that the original battery is durable and only the original battery should be replaced; some others say that the original battery is almost the same as a third-party battery and costs so much. Spend money to buy an Apple official certification, the price/performance ratio is too low; some people say that you can simply change your phone and get it right in one step.How should we maintain the battery of a new mobile phone?1. Charge the mobile phone in time when the battery level is around 20%-45%. There is no need to wait until the battery is only 0% and the phone is turned off to charge.2. A complete charging cycle should be performed at least once a month. When the battery level is below 20%, start charging until it is fully charged, and then charge for another 30 minutes.3. Try to avoid playing with the phone while charging. Playing with the phone while charging will accelerate the heating of the phone, affect the heat dissipation of the phone, accelerate the aging of the battery, and reduce the battery life.4. Avoid recharging when the battery power is lower than 20% for a long time. This will cause the battery to be in a state of power loss for a long time, which will greatly damage the battery life.You can also pay more attention to "Battery Health and Charging" in your iPhone to check the battery health of your phone. More than 90% of the battery health is considered excellent. Lower capacity may shorten the battery life after charging, which is basically 80%.  If it is lower than that, it is recommended to replace the battery.Regarding battery replacement, there are two channels to choose from: official original batteries and third-party batteries. Which of these two qualities should you choose? Which one is more suitable for you?The official original battery must be a good product selected by Apple, and the quality must be guaranteed. In terms of experience, Apple will officially refresh the key for its own battery and upload it. The battery display of our iPhone is exactly the same as before and there are no abnormalities. You can also check the battery health.However, to replace Apple's official original battery, it is best to make an appointment at the store, which can usually be replaced in 2 hours; otherwise, some stores have no stock, and it will take a week to send it for repair, which is a bit troublesome.If you replace the third-party battery with a regular brand, there will be no adverse impact on the mobile phone. Because batteries from regular manufacturers have undergone rigorous testing before leaving the factory, accidents rarely occur during normal use. Due to the different manufacturing processes of each battery manufacturer, the battery capacity will be different from the original battery, which is normal.However, you need to pay attention to the following issues:                 1. After replacing the unofficial original battery, the warranty service provided by Apple will be lost. Because Apple has stated in its maintenance policy that if the phone is disassembled through unofficial channels or after dismantling the phone by itself, it will refuse to provide repair services. This means that if a third-party battery is replaced, the original battery can no longer be officially replaced by Apple.                 2. Do not buy and use low-priced and unguaranteed battery products. There are many battery products on the market, and some low-priced batteries cannot guarantee quality and may affect mobile phones or even burn out devices.                 3. Don’t easily try to replace the battery yourself. Battery installation and replacement are best left to professional technicians. When Apple manufactures iPhones, it uses a lot of double-sided tape to fix the battery to the inner compartment of the fuselage. Therefore, when replacing the battery, it is often necessary to use a professional heat gun to heat the fuselage in order to successfully remove the battery.

Difference between Soft OLED and Hard OLEDCurrently, there are two main types of screens on the market: LCD screens and OLED screens. So what is the difference between OLED and the LCD we talk about in daily life? OLED and LCD are relatively common display technologies in the market, and each display technology occupies a certain market share in their market.       The light-emitting principle of LCD mainly relies on the backlight layer. OLED does not need a backlight layer like an LCD screen, nor does it need a liquid crystal layer to control the amount of light. It can light up as long as it is powered on, so OLED is like a countless small colorful light bulbs. OLED screens can emit no light at all when displaying black, while LCD still require backlights to operate in the background even when displaying black. The most direct effect of this mechanism is that the OLED screen can display perfect picture contrast, and the displayed picture will be more vivid and realistic. The most direct comparison is that if you put a Samsung Galaxy S8 and an iPhone 7 together, you will find that although the display effect of the iPhone 7 is good enough, the Galaxy S8 with an OLED screen is still better.Moreover, OLED screens can be made into curved screens. The reason why models such as the Samsung S8 have curved screens is because they use OLED screens, while LCD screens do not support bending due to the characteristics of liquid crystals. Another reason why Apple chose to use OLED screens may be that the current in-screen fingerprint recognition technology only supports OLED screens, because the in-screen fingerprint cables can be integrated with the screen cables.The following are the characteristics of Hard OLED and Soft OLED Kimeery OLED screen for iPhone1. Different drop resistance: Hard OLED is not as drop-resistant as Soft OLED, and many of the original screens of big-name mobile phones are flexible.2. The screen feels different: Hard OLED will feel harder when touched by hand. Soft OLED will feel soft when touched by hand, and ripples will appear if you slide the panel with your fingers.3. The process is different: Hard OLED has a layer of transparent resin material to protect the outer film. Soft OLED screens are thinner and more durable than ordinary OLED screens. The application of flexible substrates makes the screen highly impact-resistant and not easily damaged during use, and it also has unique bending and folding characteristics.4. Prices are different: Relatively speaking, the price of Soft screens is higher than that of Hard screens. Under normal circumstances, if you can choose a Soft screen, you should not choose a Hard screen. But if the user is tight on money, you can choose a Hard screen.5. The light sources are different: the light source of the Hard screen is realized by LED backlight, while the Soft screen is self-luminous. It is precisely because of the self-luminous nature of the soft screen that the power consumption of the soft screen is also Lower than Hard screen.6. Different material choices: Ordinary OLED screens use glass substrates, while soft OLED screens use plastic substrates with bendable properties. In order to ensure the reliability of the soft substrate, the soft OLED screen is encapsulated using a polymer cover plate and a special film to maintain the bending ability and folding characteristics of the screen and ensure high reliability.

iFixit has shared a teardown video of the iPhone 15 Pro Max, offering a closer look inside the device, as well as a look at how the device is built and commentary on its repairability.New Internal Design ArchitectureApple rearranged the internals, the iPhone 15 Pro and Pro Max can now be opened from both directions, all the parts are hidden behind the screen instead of behind the back glass. So it’s easier to change the back of the phone, lowering the prices of this service.But this inverted internal structure arrangement makes critical repairs like battery replacement slightly riskier than on the iPhone 14, because you're removing the expensive, fragile display instead of the glass back cover. In order to access the battery and other components, you'll have to heat up and pry off the screen, which is slightly riskier. If you accidentally rip the cables, it's better to rip the back cover cables rather than damage the display.Camera optimizationFor the first time, the iPhone 15 Pro Max comes with a 120mm equivalent 5x optical zoom camera, while the phone's main camera performance has been specifically optimized. iPhone 15 Pro Max features a telephoto lens and a quad prism system for 5x optical zoom. In terms of CMOS only, there are changes to the telephoto and ToF, while the main camera, ultra-wide angle, and front remain unchanged.Architecturally, the telephoto camera on the iPhone 15 Pro Max features a quadruple-reflective prism design combined with optical image stabilization technology and an autofocus 3D sensor displacement module. Judging from the launch photos, the autofocus 3D sensor shift module on the iPhone 15 Pro Max supports three-axis micro-motion, whereas on previous models that support periscope telephoto, it's still more likely to support a two-axis micro-motion sensor shift module.With a high-quality modemiFixit says the iPhone 15 Pro Max has a similar logic board to the iPhone 15 Pro. In addition to the A17 Pro chip, the teardown confirms that the device is also equipped with Qualcomm's Snapdragon X70 modem, which reportedly comes with an integrated AI processor designed to improve its connectivity across 5G frequencies, including shortwave millimeter wave signals. Snapdragon X70 features include the world's most complete family of 5G modems and RF systems, supporting the full range of commercially available 5G bands from 600MHz to 41GHz, providing terminal manufacturers with great flexibility to design terminals that meet the requirements of operators around the globe; unmatched global band support and spectrum aggregation capabilities, including the world's first downlink quad-carrier aggregation across both TDD and FDD spectrum.iFixit gives the iPhone 15 Pro Max an overall repair score of 4 out of 10, with higher scores representing easier repairs. The main reason for this rating is that Apple devices often require parts pairing, which can impact the ability of users and independent repair stores to perform their own repairs. However, this teardown report provides consumers with an in-depth look at the internals and functionality of the iPhone 15 Pro Max, which helps users better understand the device they own.
