Battery lifeLife falls. Using a fast charge will make the battery charge faster, but fast charging will bring more heat and pressure to the battery, thereby reducing the life of the battery. Security risks. 120W fast charge requires that both the adapter and the charging cable support high power output. If poor quality adapters and charging cables are used, it may lead to safety problems such as electrical fires. Low charging efficiency.
w Fast charge the battery. The impact of 120W on battery life is the same as that of ordinary charging, no damage is impossible, can only say that the damage to the battery is small, and the battery is in use 12After 800 charging cycles, there is still 80% of the battery capacity, and only a loss of wireless charging 20% in 800 cycles is already very low, this is already the basic standard of charging technology.
w Fast charge the battery. Even if you don't use a fast charge, the phone's battery will naturally decay. The fast charging of the mobile phone will speed up the loss of the battery and accelerate the process of the attenuation of the mobile phone battery. If the rated charging power of the mobile phone does not support the 120W charger, forced charging will also affect the mobile phone.
wThe phone cannot use a 120w charger. First of all, the 66w mobile phone refers to the maximum charging power supported by the mobile phone is 66w, while the 120w charger refers to its maximum output capacity of 120w. Therefore, if you use a 120w charger to charge a 66w mobile phone, it is likely to cause a mismatch between the power of the charger and the mobile phone, resulting in a slower charging speed or no charging.
Because of the security problem, it is not recommended to buy 120W fast charge.
