Apple's new iPhone 8 and iPhonex this year support wireless charging, which means that users only need to put them on the charging board during charging, no need to insert Lightning cable to achieve charging. Then when the fruit powder is using wireless charging, it has encountered many questions, such as whether the wireless charging function is good or not, how to use the wireless charging of the iPhoneX and what needs to be paid attention to? The following small series will answer these questions for you.
Disadvantages of wireless charging1. Wireless charging causes environmental hazards
Let's first discuss the downside of the wireless charging feature because it is important. The wireless charging board is inefficient, and depending on the design and the location of the user's mobile phone on the charging pad, the charging efficiency may be between 30% and 80%. This means that even under ideal conditions, 20% of the energy is wasted. Although charging efficiency has been increasing, low-power charging (such as mobile phones) is less efficient than high-power charging (such as electric cars) - efficiency is close to wired charging.
Charging efficiency may not be a big issue for every device. But Apple sells 10 iPhones per second, which means that wireless charging boards will soon become popular. In the next few years, the number will be tens of millions, and the waste of electricity will be huge. This is bad news for the Earth's ecological environment and climate change.
Apple's senior vice president of global marketing, Phil Schiller, announced at the 2017 iPhone new product launch that Apple is trying to "make the wireless charging experience better," but doesn't mention charging efficiency. Schiller focused on charging the same device on the same charging board, allowing the charging pad to communicate with the iPhone and display the power on the lock screen. Charging efficiency is undoubtedly a priority, so Apple may drive the wireless charging efficiency of the entire mobile phone industry.
2. Can't move iPhone
Cult of Mac said that another major disadvantage of wireless charging is that it is much more difficult to use the phone while charging. With the wired charging method, the user can move while holding the phone while charging - although limited by the length of the cable. When using wireless charging technology, the phone must be placed on the charging pad. If the user only plays music while the phone is charging, there is no problem, but it is painful to let the phone perform other functions. Since it is impossible to take the phone and input the text, it is hard to send a text message.
1.Lightning cable wear reduction
On the other hand, the popularity of iPhone wireless charging will reduce the use of cables. The wear on the cable will be reduced to almost zero. Simply plug the wireless charger AirPower into the power supply, and everything will be fine. Users no longer need to insert and remove the phone frequently, reducing the wear between the Lightning cable and the interface.
2. Convenient, especially when charging multiple devices
The biggest benefit of wireless charging is convenience. Wireless charging has little effect on mobile phones, but when all electronic products support wireless charging, the convenience for users is more interesting. Apple said that future models of AirPods wireless headphones will use AirPower-enabled charging boxes, so users only need to put them on the charging pad to charge. The Apple Pencil stylus is in urgent need of wireless charging, and its current charging method is simply a joke.
Wireless charging is ideal for small electronic products. Imagine placing a charging pad in your desk drawer that allows users to charge the iPhone's spare battery and keep it fully charged when needed. In addition, users only need one charging pad to charge multiple devices. For example, when a colleague charges the iPhone, the user does not need to unplug his iPhone.
3. Wireless charging helps improve security
Using wireless charging technology means that users don't need to connect the iPhone to an unknown cable, which is the hiding place for all malicious parts. Putting the iPhone on the charging pad should be safe—unless a hacker develops a malicious piece that uses wireless charging, so far, such a malicious piece does not exist. After the iPhone supports the charging pad, we can expect that in the near future, the charging pad will appear in hotels, restaurants and other public places.
Fruit powders should be aware that the iPhone 8 and iPhoneX launched at the Apple Autumn Conference in 2017 are based on Qi wireless charging technology. This technology has its drawbacks and needs to strictly adhere to the charging precautions, otherwise the consequences are very cool.
Instructions for wireless charging the iPhone are as follows:
1) Wireless charging uses magnetic induction to charge the iPhone;
2) Do not place anything between the iPhone and the charger;
3) Magnetic enclosures or other objects may degrade performance or damage magnetic strips or RFID chips in certain credit cards, security badges, passports and key chains.
For all these sensitive items, please remove them before charging, or make sure they are not between the back of the iPhone and the charger, and this security applies to almost all smartphones that support wireless charging, not just iPhoneX and iPhone8.
1. Connect the charger to the power supply. Use the power adapter that came with the accessory or the power adapter recommended by the manufacturer.
2. Place the charger on a level surface or at another location recommended by the manufacturer.
3. Place the iPhone on the charger with the display facing up. For best performance, place your phone in the center of the charger or at the manufacturer's recommended location.
4. The iPhone should start charging after a few seconds on the wireless charger. You should see the charging indicator in the status bar after starting charging.
Wireless charging uses the principle of magnetic induction to charge the iPhone. Do not place anything between the iPhone and the charger. If you place a magnetic stand, magnetic case, or other object between the iPhone and the charger, it may degrade the performance of the charger or damage the magnetic strip or RFID chip (often in some credit cards, security signs, passports, and smart keys). in). If you have these sensitive items in your protective case, remove them before charging or make sure they are not between the back of the iPhone and the charger.
The iPhone does not charge wirelessly when connected to USB. If your iPhone is connected to your computer using USB or connected to a USB power adapter, the iPhone will be charged using the USB connection.
If your iPhone vibrates (for example, when you receive a notification), the iPhone may shift. This may cause the charging pillow to stop providing power to the iPhone. If this happens frequently, consider turning off the vibration function, turning on the Do Not Disturb mode, or using a protective case to prevent movement.
Depending on the charging pillow you are using, you may hear a slight noise when the iPhone is charging.
If your iPhone is not charging or charging slowly, and your iPhone is equipped with a thick protective case, metal case, or battery case, try removing the protective case or case.
The iPhone may be a little hot when charging. To extend battery life, if the battery is overheated, the software may limit charging when the battery reaches 80%. When the temperature drops, the iPhone will charge again. Try moving your iPhone and charger to a cooler location.
Although the iPhoneX already supports the functions of fast charging and wireless charging, the original power supply of the iPhone 8 and iPhoneX is still the standard 5V/1A specification, which is basically unchanged from the iPhone 7. In other words, the iPhone X you bought back does not support fast charging and wireless charging by default. Apple's promotion of wireless charging and fast charging is conditional. Users need to buy a fast charging charger or a wireless charger separately.
As a flagship mobile phone of nearly 10,000 yuan, although the iPhoneX already supports wireless charging and fast charging, the accessories are not equipped with a fast charging charger and a wireless charging device, but need to be purchased separately by the user, and need to wait until next year to purchase. . From this point of view, compared with Android phone manufacturers, Apple is really unacceptable to users.

In short, Dashcoin Dash is a variant of the Bitcoin cryptocurrency that runs on the same blockchain network. Dashi, which combines the words "digital" and "cash," has become one of the most widely watched counterfeit coins in recent months. Originally released as "XCoin", it was later changed to "Darkcoin" and later Dash.
Arguably the biggest benefit of Dashi is that its transactions can be sent completely anonymously, just like legal cash payments. This is achieved by using a hybrid protocol that operates a dedicated network of servers called Masternodes. While Bitcoin operates only a single-layer network of miners, Dashcoin uses these master nodes as additional layers to its network, eliminating the need for a trusted third party to authorise a transaction that could compromise the anonymity of any payment.
Another major difference between Dashcoin and Bitcoin is that the former distributes mining rewards between its mining community, participants holding a specified amount of Dash, and the Dash community's long-term development fund.
