With the continuous evolution and popularity of mobile games, they have gradually evolved into a part of social networking, and friends and colleagues can quickly get acquainted with each other when they play "Glory of Kings". At present, the middle and high-end mobile phone markets are basically difficult to distinguish between high and low on the performance track, and the game experience has become a major selling point that users are more concerned about.
After a long time of play, the lack of power will make users extremely irritable, so domestic mobile phone manufacturers began to "play while charging" as a selling point. Today, the author took three new machines with a price of about 3,000 yuan (Redmi K50 e-sports, iPhone SE3, Red Devil Game Mobile 7) to do a simple test to see if it can achieve the effect of manufacturer publicity.
First of all, let's introduce the test environment, the power of the three mobile phones is maintained at 50%, the airplane mode is turned on and Wi-Fi is connected, NFC, Bluetooth, and location services are turned off, and the screen brightness is set to the highest. The test game is Original God, and the game quality is high (default) +60 frame mode. Redmi K50 Esports Edition turns on flash charge acceleration.
The battery life of the three mobile phones is as follows:
Redmi K50 esports edition built-in 4700mAh battery, support 120W fast charging, "Glory of the King" while charging while playing 37 minutes full;
The Red Devils game phone 7 has a built-in 4500mAh battery, supports 120W magic flash fast charging, and both Android phones are equipped with the new Snapdragon 8 chip;

The iPhone SE3 has a built-in about 2200mAh battery and supports 20W fast charging.
The iPhone SE3 performs as follows:

30 minutes to play down, the iPhone SE3 game experience can be said to be one of the worse of the three models, frequency reduction occurs repeatedly, the screen is bright for a while and dark for a while, accompanied by sudden frame drop, Drop occurs. However, the unit is charged with 30% of the power in 30 minutes, and after 80% it will enter a long trickle charge.
The average temperature of 10min, 20min and 30min is about 42 degrees, and the maximum temperature is 47.8 degrees
In our iPhone SE3 comprehensive review, 30 minutes can charge about 62% of the power for the phone, and the peak charging power is about 18W. The reason why the iPhone SE3 can get a 30% charge score is largely because it also has a small battery with a small capacity of 2200mAh.
The Red Devils 7 performs as follows:

At present, most of the common game flagships on the market will not be too restrictive of game performance, can be pulled full, the same is true of the Red Devils 7: it is the best performance of the game screen in this game while playing and charging test, rarely dropped frames, almost full frame running, but the relative body temperature is also full: the highest place is close to 60 degrees.
The average temperature of 10min, 20min and 30min is about 45 degrees, and the maximum temperature is 59.4 degrees
In order to avoid excessive internal component temperature, the charging power of the Red Devil 7 was also limited, and the power was limited to less than 24W in the 30-minute test, and finally charged to 79%.
Before we also published a related article on science, mobile phone batteries will cause heat accumulation due to the energy loss of voltage and current when charging, and the capacity decay of the cycle battery at room temperature is relatively slow, but once the temperature is too high or too low, it will quickly affect the internal activity of the mobile phone battery. In addition, the built-in CPU of the user itself will also heat up when using the mobile phone, and the charging power reduction is also an indispensable measure.

In order to reduce the heat of the game, the Red Devil Gaming Phone 7 has a built-in "bypass power supply" function, which only powers the system and does not charge the battery after opening. The heat effect will indeed be weakened, but playing for a few hours can not fill 1% is it.
The Redmi K50 esports edition performs as follows:
As can be seen from the above figure, the Redmi K50 e-sports version in the first 5 minutes of playing "Original God" at the same time, the first 5 minutes actually charged 25% of the power, although the speed of the phone after heating up has decreased, but still within 20 minutes will be fully charged, the results are very eye-catching.
The average temperature of 10min and 20min is about 44 degrees, and the maximum temperature is 47.2 degrees
The Redmi K50 Gaming Edition really doesn't brag, thanks to the built-in discrete IC design, the heat converted from the power lost during charging does not further affect the soC's heat. At the end of 2019, iQOO proposed a two-way IC separation design concept, which has two built-in charge pump ICs, which have higher conversion efficiency than single charge pump ICs and can maintain peak charging power for a longer period of time.

summary
One word to sum up the test while charging is "power". Mobile phone charging technology is constantly developing, although there will often be similar accidents such as "playing while charging to cause fire", but most of them occur on old models. While playing, charging is no longer a "flood beast", as long as it is matched with the appropriate cooling means, it can be used with confidence.
