iPhone 8 Plus fast charging speed is amazing: want to add money

Apple did not let us down in September, released three new mobile phones in one breath, of which iPhoneX attracted countless eyeballs with a full-screen design, but Apple did not put all the energy on the iPhoneX.

The newly released three mobile phones have many of the latest technologies, such as the powerful A11 bionic processor and wireless charging.

Among them, there is an important feature on the iPhone 8/8 Plus and iPhoneX that was not mentioned at the press conference. In this article, the author will take a deep look at the fast charge, wireless charging and battery life on the iPhone 8/8Plus.

We all know that the official iPhone charger is always 5V/1A, and the charging speed is quite slow. We don’t feel slow in the iPhone4 era, because the battery capacity of the iPhone is 1400 mAh. Left and right, one and a half hours can be almost full. ▲ Apple iPhone's constant power adapter

Starting from the iPhone6 ​​Plus, the battery capacity of Apple's big-screen iPhone has risen to nearly 3,000 mAh. It takes nearly three hours to fully charge the 5V/1A charger, which is really a crash.

But what is even more frustrating is that Apple has been equipped with the latest release of the iPhone 8/8 Plus and iPhoneX, which is still equipped with a 5V/1A power adapter model A1443.

The good news is that although Apple's new product launch did not mention it, this year's three new iPhones support PD fast charging. How powerful is PD fast charge? Look down.

Apple iPhone8/8P supports PD fast charging protocol

Although Apple's iPhone did not directly have a fast charge, we found that it can also charge the iPhone with the iPad's 10W or 12W charger, and the charging speed is faster than the 5V/1A, which is unchanged for a year, and Apple's official website also admitted. You can use the iPad's charger to charge your iPhone, iPod, etc., and the charging speed will be faster. â–² Apple's official website explanation The official website's technical support page indicates that you can use the Apple 12W and 10W USB power adapter to charge iPad, iPhone, iPod, Apple Watch and other Apple accessories.

When charging some Apple devices and accessories with the Apple 12W or 10W USB power adapter, charging is faster than a 5W power adapter.

After the actual measurement, when using the 12W power adapter to charge the iPhone, it can basically reach the charging level of 5V/2A, which is 10W.

However, this speed is still much lower than the 18W or even 25W charging level popularized by the current android flagship mobile phone.

Maybe you will ask what is the meaning of fast charge. In fact, the author thinks that fast charge is a compromise.

At the moment when the development of battery technology encounters bottlenecks, our pursuit of ultra-thin body, larger screen and high-performance computing speed has not stopped. At this time, the appearance of fast charging can reduce the waiting time of our charging. To make our experience better.

Before the release of Apple's iPhone 8/8 Plus and iPhoneX, there were many rumors that the new iPhone will be equipped with a fast charge.

At the press conference, Apple did not mention the fast charge. But the eye-catching netizens still found the charging part of Apple's official website about the technical specifications of the iPhone 8/8 Plus and iPhoneX. â–² Apple's official website iPhone8/8 Plus and iPhoneX parameters

It can be seen that Apple iPhone 8/8 Plus and iPhoneX support fast charging, and can charge up to 50% in half an hour. Just now, Apple iPhone 8/8 Plus and iPhoneX are equipped with 5W chargers. So what exactly is the charger that can achieve such a fast charging speed? â–² Apple's official website comment on this fast charge data, Apple gave the explanation: Apple in August 2017 using the trial production of iPhone8 and iPhone8 Plus models, software and the corresponding Apple USB-C power adapter (29W model A1540 This test was carried out with the 61W model A1718 and the 87W model A1719.

The quick charging is based on the trial of the various iPhone models, and the charging time varies according to environmental factors. Actual results may vary.

The 29W model A1540, 61W model A1718, and 87W model A1719 mentioned above are power adapters used by Apple MacBooks and MacBook Pros.

These power adapters have USB PD characters, which means that Apple iPhone 8/8 Plus and iPhoneX support PD fast charging.

So what is this PD fast charge? "PD refers to Power Delivery, which focuses on two or more devices, or even a power transmission process based on a USB interface. The power transmission can be bidirectional or even networked. It can be system level. Power supply strategy.

USB Power Delivery is the power transfer protocol, and the USB PD protocol is based on USB 3.1. It is the power transfer concept proposed in USB3.1, ie type-c port.

This technology can bring greater flexibility and expand the charging capacity to 10 times the current level: up to 100 watts. "The above explanation is from Encyclopedia.

In layman's terms, the PD charging system can be divided into three levels from low to high, namely the USB Tpye-C connection layer, the PD protocol layer and the system charging strategy layer.

The Tpye-C connection layer needs to ensure that the two devices are connected to each other to avoid repeated confirmation of who is charging, how much voltage and current to charge, etc., and the protocol layer provides the specification of this confirmation process.

The system charging strategy layer is different for each manufacturer. For example, the charging strategy of the Apple iPhone 8 is to charge quickly and then trickle to extend the battery life. And how much power is used to enable slow charging. This is the different strategy of each manufacturer.

It doesn't matter if you don't understand, you just need to know that this is a fast charge agreement.

Why do you need an agreement for fast charging? Because the implementation of fast charge is not only a simple charging head, but also involves voltage and current, data lines, batteries, processors, etc., all of which can be adapted to achieve fast charging in this protocol.

At present, many manufacturers' machines are already equipped with flash charging, and most of them use Qualcomm's QC protocol, MTK's PE protocol and OPPO's unique VOOC flash charging. â–² Qualcomm QC3.0 Maybe you can't tell which protocol you and your colleagues use to support the phone, but sometimes charging with someone else's charger is very fast, sometimes it is very slow, which involves the fast charge agreement. Also incompatible.

Unlike before, everyone is a 5V/1A charging head that can be charged. Now maybe your charger is high voltage and low current, and he is low voltage and high current. You support this protocol. He supports that protocol, and everyone can't share a charger happily.

At this time, the PD protocol is very important. Just mentioned that PD refers to Power Delivery, which is concerned with two or more devices, or even a power transmission process based on a USB interface. The power transmission can be bidirectional. Or even networking, you can have a system-level power supply strategy.

In other words, if the PD protocol is popular, you can use your colleague's charger to quickly charge your phone.

Having said that, let's take a look at the fast charging of the iPhone8 Plus!

Apple iPhone8 Plus fast charge test

How many pieces of iPhone 8 can be charged with the 29W model A1540, 61W model A1718, 87W model A1719 power adapter? How long does it take to charge the iPhone 8/8 Plus with a USB PD charger?

High-power charging, will the phone be very hot? Let's take a look together.

According to the test of the charging head network, the test environment temperature is about 28 ° C, choose iPhone8 Plus to use Apple's official 29W charger, Apple's official double-head Type-C line and Type-C to lightning line; the entire test process data using POWER-Z KM001 is monitored throughout.

In addition, the charging temperature of the mobile phone is obtained by the FLIR thermometer. The voltage and current curves during the entire charging process recorded by POWER-Z KM001 are obtained. Yellow indicates voltage and cyan indicates current. â–² iPhone8 Plus charging situation can be seen, the voltage of the Apple iPhone8 Plus charging process is not constant, the voltage is intelligently maintained at about 14.5V for about 70 minutes, and the trickle charge is automatically enabled in the later stage of charging, that is, 29W The charger can only be charged at 5V later, until the phone is full.

By grabbing the voltage and current diagram, the power curve during the charging process of the Apple iPhone 8 Plus can be obtained. â–² Apple iPhone8 Plus fast charging power curve

Through the fast charging power curve of Apple's iPhone8 Plus, we can see that the peak power is 1 minute and 07 seconds just plugged in, reaching 19.49W. At this time, the power is not very stable. After a few minutes, the power is stable. 15W or so.

It can be concluded that the Apple iPhone 8 Plus has a power stability of 15W when it is fast-charged with a 29W model A1540 power adapter.

At 1 hour and 22 minutes, the charging power gradually decreased. At this time, the voltage stabilized at 5V, and the current gradually decreased until the mobile phone was fully charged. The entire charging process lasts for 2 hours and 30 minutes. â–² Apple iPhone8 Plus fast charge curve From the recorded Apple iPhone8 Plus charging curve, we can more intuitively see the two and a half hours of charging.

In 30 minutes, it is charged with 41% of the electricity, and Apple's official said that the maximum charge of 50% is not big, probably because Plus is the reason for the big battery.

At 1 hour and 02 minutes, 77% of the charge was charged, and at this time, it was switched to trickle charge.

The charging speed gradually slowed down until 2 hours and 26 minutes, and the Apple iPhone 8 Plus was fully charged. Although this achievement is not very fast in today's Android flagship. However, it will take a three-and-a-half-hour period to fully recharge the Plus phone.

The only thing that is embarrassing is that the last 10% of the power of the Apple iPhone 8 Plus takes an hour to fill, which can be a torment for users with obsessive-compulsive disorder.

However, the first 80% of the electricity will only be filled in an hour or so, which is good news for users with fast charging needs.

Since charging is so fast, you must be worried about the fever of your phone. The measured Apple iPhone 8 plus was charged for 45 minutes at room temperature of 28 ° C and the temperature was about 46 ° C. After charging for 60 minutes, the temperature was about 41 °C. ▲ Apple iPhone8 Plus fast charge fever can be seen in the 45 minutes of charging, the phone's heat reaches the highest, 46 ° C temperature for our palms can still feel a certain amount of heat.

The material of the mobile phone has a certain influence on the temperature we feel. The metal material will look hotter, but fortunately, the Apple iPhone 8 Plus uses the design of the back glass. The measured temperature of the palm is about the heat of the iPhone 7 Plus when playing a large game.

Now it seems that Apple iPhone8 Plus's fast charge is still very powerful, but ... fast charge power adapter and USB Type-C to Lightning cable need to buy their own, let's look at the price. â–² Apple fast charge equipment needs additional purchase The cheapest 29W power adapter plus USB Type-C to Lightning cable price is 576 yuan.

You may say, this line I go to Tmall Taobao to buy it, there are many bargains, but this line must be Apple's original USB-C to Lightning, the only choice now.

Due to the limitations of the agreement, the switch solution was not available. Apple did not open the C52 plug to third-party vendors, so there was no third-party mfi solution. This is the pit! Want to fast charge, you have to add money! But Apple's products don't seem to be cheap, let's take it!

Apple finally supports Qi wireless charging

Speaking of the Apple iPhone8/8 Plus and iPhoneX with a glass back panel design, you have to talk about the wireless charging that the three new iPhone products support. ▲ Apple Wireless Charging Air Power Apple iPhone supports Qi wireless charging standard. “Qi” is actually the pinyin of “qi” in Chinese, which represents the “power” in Asian philosophy. There is also a small allusion, which is of interest. I can go and have a look.

Back to the point, Qi is the world's first wireless charging technology standard to promote wireless charging technology - Wireless Power Consortium (Wireless Power Consortium) introduced wireless charging standards, with convenience and versatility.

First of all, different brands of products, as long as the Qi logo, can share the Qi wireless charger charging. Secondly, it overcomes the technical bottleneck of wireless charging "universality". In the near future, mobile phones, cameras, computers and other products can be charged with Qi wireless charger, providing a possibility for large-scale application of wireless charging.

This is exactly what Apple said at the press conference. In the future, you can use Qi's standard wireless charger to charge at the mall, airport and other places.

The Qi standard wireless charging supported by the Apple iPhone 8/8 Plus can reach a charging power of up to 7.5W. â–² Apple's wireless charging power is up to 7.5W Although Apple's Air Power wireless charger will not be available until next year, there are already many charging docks on the market that support the Qi wireless charging standard. Apple also has two wireless charging docks on the official website. â–² Apple's official online wireless charging dock, the Apple store is still as expensive as ever... bought Apple iPhone8/8 Plus or iPhoneX, if you want to join fast charging and wireless charging, then you have to Add a thousand yuan or so.

This turned out to be a bit like buying a car upgrade configuration, Apple's money-making Dafa author had to serve.

Apple iPhone 8 Plus battery life is not too many surprises

After talking about charging, let's talk about battery life. Although Apple made a lot of new breakthroughs in charging, it is the basis of battery life - battery, iPhone8 (1861mAh) 丨 8 Plus (2675mAh) in terms of capacity and previous generation data. Not only did it improve, but it declined slightly.

However, according to Apple's official propaganda, the iPhone8丨8 Plus is about the same as the previous generation in terms of battery life. According to the data of the iPhone7 Plus, the iPhone8 Plus's battery life should be good. We used the Apple iPhone 8 Plus with a larger battery capacity for endurance testing. The test standard is the five-hour heavy test of Zhongguancun Online Evaluation Center.

* Photo test (30 minutes): Use the system default camera, do not enable the flash, take a total of 20 photos in 10 minutes, take a photo every 30 seconds.

Forcibly enable the flash, use the system default camera, take a total of 5 photos in 10 minutes, and record the remaining power after the test is completed. Use the system default camera app to shoot a 10-minute video at the maximum resolution that can be supported, and record the remaining charge after the test is complete.

Video playback test (60 minutes): Select the iQiyi player, select 1080p episode playback, turn on the sound and adjust the volume to medium, and the project test time is 1 hour. Record the remaining charge after the test is completed.

Social test (30 minutes): Select Sina's official Weibo client, and open 30 picture big pictures, 15 gif format pictures, click on the two Weibo comment boxes and read them all, and play them on Weibo. Two small videos of 1~2 minutes.

Refresh Sina's "Top Weibo" homepage every 5 minutes, the test time is 30 minutes. Record the remaining charge after the test is completed.

Instant messaging (30 minutes): Open WeChat, send a 10 second voice and 2 text messages every 1 minute in the first 10 minutes. The content of the message is free. Control within 1 line, 10 minutes in the middle, send every 2 minutes. Ordinary photos taken by mobile phone and 2 text messages.

After 10 minutes, open a photo posted by a circle of friends every 2 minutes and send 2 text messages. Clear the background and record the remaining battery after the test is completed.

Web browsing (30 minutes): Open the mobile QQ browser, open a news every 3 minutes, open 10 news pages in total, the project test time is 30 minutes, after the test is completed, clear the background, record the remaining power after the test is completed.

Game test (60 minutes): Select "NBA2K17" game, the project test time is 60 minutes, after the test is completed, clear the background, record the remaining power after the test is completed.

Since the "NBA2K17" game on Apple's iPhone 8 Plus flashed back, we used a similarly sized "Vaan Vainglory" game to test.

Online music (30 minutes): Use Netease Cloud Music to play the hot list of the day, play in sequence, the project test time is 30 minutes. After the test is completed, the background is cleared, and the remaining power is recorded after the test is completed.

E-book (30 minutes): Read the eReader by reading the iReader reader, turn the page once in 1 minute, the screen stays lit, and the project test time is 30 minutes. After the test is completed, the background is cleared, and the remaining power is recorded after the test is completed. â–² Apple iPhone8 Plus five-hour battery test After five hours of heavy endurance test, Apple iPhone8 Plus has 28% of the remaining power, this battery life level can only be discharged to the lower-middle level in our product library.

Compared with the previous generation, the Apple iPhone7 Plus has 29% of the remaining power for five hours. It seems that Apple is really not wrong, and the battery life level is the same as that of the previous generation. But compared to the remaining 40% of Samsung Note8's power is still worse.

In short, this generation of Apple iPhone8/8 Plus does improve a lot in charging performance, not only added PD fast charge, but also joined Qi unlimited charging, but Apple's accessories strategy is still very pit.

In terms of battery life, although the battery capacity of the iPhone 8/8 Plus is reduced compared with the previous generation, the processor with the more advanced process and the iOS11 system make the iPhone 8/8 Plus last the same as the previous generation.
