Is oppo mobile phone flash charging good?

Although flash charging is a patented technology of oppo, neither the mobile phone nor the charger will generate heat, but I personally suggest not to use flash charging. Lithium battery charging is the conversion of chemical substances in the battery, and the electric energy is converted into chemical energy for storage, which is easy to cause hidden dangers and affect the battery life. What do you think will happen if the wind speed is fast enough? What does it mean for a chemical reaction to reach a certain level in a narrow space? Therefore, charging for 2 hours is enough. Now the flash charging technology needs to update the battery. If the battery directly stores electric energy, then flash charging is meaningful. Thank you.
