How long does it take to charge the 18650 lithium battery of an electric toothbrush?

How long can an electric toothbrush last on a single charge? What exactly caused this difference?

At present, there are various electric toothbrushes on the market, some say they can be used for 25 days, some say they can be used for 35 days, and some say they can be used for 60 days? What is the reason behind this difference?

In fact, there are several factors that affect this:

1. Capacity of rechargeable lithium batteries
Usually there are 500mA, 600mAh, 800mAh, 1000mAh
The larger the capacity, the longer the usage time

2. Power consumption of the circuit board
The more components on the circuit board, the stronger the function, and the more energy is consumed

3. Power consumption of the motor
The higher the rotational speed, the less power is needed and the more energy is consumed

Usually, these three factors together determine the usage time, and these three factors ultimately determine one factor - the price at which you purchase the product. The higher the price, the higher the configuration, haha!
