Fast charge in the end does not hurt the battery, I believe that this problem has been plaguing many users. It's not a complicated question, and the answer must be yes. Because as long as it is charged and discharged, it will cause irreversible damage to the battery, and Apple and Samsung have been conservative about fast charging. Fast charging is necessarily a double-edged sword, but the extent of damage is difficult to determine.
Understand the super fast charge principle
If you want to know how much fast charging affects the battery life of mobile phones, first look at the principle of fast charging technology. At present, there are many schemes for fast Charge technology, such as Apple's PD protocol, Qualcomm Quick Charge protocol, etc., from the charger output standard to the control IC and even the power cord have corresponding standards, through the Customized " Get the most out of your phone's battery.

Most of the fast charge protocols are essentially high current or high voltage
But everything changes, and most fast charging technologies are nothing more than that. High current or voltage; To achieve super fast charge, this is fundamental, so it is inevitable that high temperature, high pressure and other easy to damage the battery behavior. Various protocols are more to communicate charging components and limit voltage and current, and regulate according to temperature, so as to protect the battery.
Three factors that damage batteries
The three major fatal factors that lead to battery acceleration damage are nothing more than high temperature and high pressure, current instability, overcharge and overload. Among them, the problem of current instability as long as the original charger is guaranteed, do not worry too much. The same is true for overcharge and overload, the fast charging agreement will carry out super fast charging in the first 80%, and trickle charging will be carried out when it is fast filled to avoid overcharge.

Heat is the key to damaging your phone's battery life
Perhaps many people have experienced that the temperature of the mobile phone rises significantly when it is fast charged. So, now the answer to the question is more clear, in fact, whether fast or slow charging, there is a reasonable battery life damage. However, if the high voltage or high current used in fast charging causes high temperature problems, it will undoubtedly become the key to accelerating battery damage to battery life.
Knowing the root cause of the problem is the key to solving it. So if your phone supports super fast charge, what can you do to better protect your phone battery? Although it is not expensive to change the battery now, the advanced waterproof of the IP68 machine will be wasted once it is removed. In fact, the solution is very simple, is as far as possible to avoid the super fast charge caused by the problem of overheating the battery.
