Mobile phone fast charge and slow charge cost comparison?

The cost comparison between fast charging and slow charging of mobile phones varies depending on the brand, model, power and other factors. In general, the power and speed of fast charging are higher than that of slow charging, so the cost of fast charging is also relatively high. Specifically, the following is a comparison of fast and slow charge costs for some common mobile phone brands and models:

Xiaomi: The fast charge and slow charge costs of Mi 9, Mi 9T, Mi 9T Pro and other models are as follows:

Fast charge: 10W, power is 3.5W, charging time is 30 minutes, the cost is about 10 yuan\/time.

Slow charge: 5V, power is 2.5W, charging time is 1 hour, the cost is about 10 yuan\/time.

OPPO: The fast charge and slow charge costs of OPPO Reno, OPPO Reno Pro and other models are as follows:

Fast charge: 5W, power is 3.5W, charging time is 30 minutes, the cost is about 10 yuan\/time.

Slow charge: 5V, power is 2.5W, charging time is 1 hour, the cost is about 10 yuan\/time.

iPhone: The cost of fast and slow charging for the iPhone 12, iPhone 12 Pro and other models is as follows:

Fast charge: 20W, power is 4W, charging time is 30 minutes, the cost is about 10 yuan\/time.

Slow charge: 5V, power is 2.5W, charging time is 1 hour, the cost is about 10 yuan\/time. It should be noted that the above data is for reference only, and the actual cost may vary depending on the brand, model, power and other factors. At the same time, the advantages and disadvantages of fast charging and slow charging also need to be selected according to personal needs and actual conditions.


2. The reason is that the charger used for slow charging has lower power and slower charging speed, so the charging pressure on the battery is smaller, which can better protect the battery life and extend the service life of the battery.
The charger used for fast charging has higher power and faster charging speed, but it will generate greater heat, cause certain damage to the battery and shorten the life of the battery. 3. In addition, slow charging can also reduce the overheating of the battery, improve the charging efficiency, and avoid safety problems caused by overheating of the battery. Therefore, although the charging speed of slow charge is slower, in the long run, the cost of slow charge is lower, and it can better protect the mobile phone battery and extend the service life of the mobile phone.


1. Low cost of slow charging. 2. The reason is that slow charging is slower than fast charging, and will not generate too much heat and pressure on the battery, thus reducing the loss of the battery and the risk of shortening life. In addition, slow charging also does not require additional high-power chargers and cables, and the cost is relatively low.
3. Despite the low cost of slow charging, fast charging still has advantages in some specific scenarios.
Fast charge can quickly fill the battery in a short time to facilitate the user's urgent use. In addition, some new fast charging technologies are also constantly developing, improving charging efficiency and safety, and further enhancing the use experience of fast charging.
Therefore, when choosing the mobile phone charging method, it is necessary to consider it comprehensively according to the specific needs and situations.


For example, the same 4,000mah battery. Fast charge takes 1 hour, slow charge takes 3 hours.
