Huawei mate 30 uses a 6.62-inch piece on the frontFull screen, resolution 2340-1080. The new generation of the Qilin 990 flagship chip is adopted, and the 7-nm process is adopted. Built-in 4200 mAh battery, support 27W wireless super fast charging.

Because it supports 27W wireless super fast charging, Huawei has released a 27W wireless super fast charging Wireless charger that matches it.

Use the Huawei 40W charger (Huawei Mate 30 series standard charger) as input to monitor the input end with the ChargerLAB POWER-Z KT001 portable tester, and Huawei's original 5A data line is connected to the Huawei 27W wireless charger as the power line.

After Huawei Mate30 is placed on the wireless charger, the screen displays multiple lightning icons and current power, and a striking line of "wireless super fast charging" appears below, indicating that 27W super wireless charging is under way.

At this time, the input power is about 34.1W (9.9V3.5A). After efficiency conversion, the final wireless charging power can indeed reach Huawei 27W super wireless fast charging level.

In addition, Huawei has a 15-W power-based wireless charger, and we also look at how it will behave to the Mate 30.

Huawei mate30 is placed on the wireless charger. At this time, the input power is about 13.7w (8.92v1.53a). After efficiency conversion, the final wireless charging power can indeed reach Huawei's 10W wireless fast charging level. Mate30 supports Huawei's 10W wireless fast charging.

Next, Xiaobian will use Huawei 27W super fast charging Wireless charger and 15W wireless fast charging charger to charge mate 30 in the whole process to see how it performs. This test uses chargerlab power-z km001 to monitor and record the upper computer data, which is made into the following table.

The first is to use the Huawei27W super fast charging wireless charger, when the Mate 30 starts charging, the Huawei wireless charger turns on 27W wireless output mode, the power of the input is up to 36W; with the increase of temperature, the stable high power lasts for nearly 5 minutes, then the input power begins to fluctuate, and the fluctuation range is 16W~30W; overall, the input power of the Huawei wireless charger is maintained at 16~30W, and the power of charging 1 hour and 8 minutes is greatly reduced into the trickle mode, and the full power of 36.45W.

Let's look at the increase in the power of the Huawei Mate 30. In the high-power stage of the last five minutes, charge the power of 10%, fill in 44% of the power in half an hour, charge 87% for an hour, and fill the whole process for 1 hour and 30 minutes. This wireless charging speed has been close to some.cellphoneThe cable is about to be recharged.

We can also see from the electricity change curve that the mobile phone's electricity is constantly rising rapidly, after reaching 94%, the speed slows down to enter trickle mode, so as to obtain a fuller charging effect.

Then there is the use of Huawei 15W wireless fast charger, when the Mate 30 starts charging, the wireless charger turns on 15W wireless output mode, and the maximum power of the input soared to 13.88W; as the power begins to fluctuate, the fluctuation range is 11W ≤ 14W, and most of the whole charging is maintained at this power stage; finally, the power drops sharply in 1 hour and 41 minutes and switches to trickle mode. The maximum power of the whole process is 14.78W.

Let's look at the increase in the power of the Huawei Mate 30. Five percent of the power is charged in the first five minutes. The amount of power is charged to 27% for half an hour. The amount of power is charged to 53% for an hour, and an hour and a half are charged to 82%, and the whole process is full of 2 hours and 20 minutes.

We can also see from the electricity change curve that the mobile phone's electricity is rising rapidly. When it reaches 92%, the speed slows down and enters trickle mode, so as to obtain a fuller charging effect.

The use of Huawei 27W super fast charging wireless charger is much faster than Huawei 15W wireless fast charger to charge the Mate 30, and the whole process is nearly an hour faster. In addition, both chargers change to trickle-down charging mode when charging the Mate 30 to 90 percent, so the subsequent charging time will appear longer.

Summary of charging head net:

The Mate 30 supports 27W wireless super-fast charging. It is very fierce. It is actually measured. The matched Huawei 27W super-fast charging wireless charger is charged. The maximum power of the input end of the wireless charger can reach 36W, and the high-power stage of 30W is maintained for nearly 5 minutes. Most of the time power fluctuates between 16 and 30W. In addition to the 27W, it also supports the 10W Huawei wireless fast charging protocol, which is a choice for consumers.

Huawei Mate 30 has 4200mAh battery capacity, using Huawei 27W wireless charger for five minutes can charge 10% electricity, half an hour to charge 44% electricity, an hour to charge 87%, the whole process full time 1 hour and 30 minutes, the performance is very good, even faster than some wired charging phones, compared with Huawei 15W wireless charger charging speed, the advantage is more obvious.

In addition, whether it is 27W wireless fast charging or 10W wireless fast charging, the charging strategy will be changed after the charging reaches 90%, and another low power trickle mode will be used for slow charging in order to achieve a fuller filling effect. Wireless charging technology has been developed for so many years, the introduction of high-power wireless charging technology, so that mobile phone wireless charging from "can" to "easy to use", so that consumers are more willing to use wireless charging, mobile phone daily use experience also has more changes.
