Which has a great influence on battery life, mobile phone charging, fast charging and normal charging?

In principle, the damage of the battery basically comes from two aspects: on the one hand, when the battery is charged and discharged, the anode and cathode of the battery will shrink and expand with the release and absorption of ions, and the chemical substances on the battery will be destroyed after long-term rapid charging, thus shortening the battery life. On the other hand, when charging quickly, the thermal effect of the current will be intensified due to the relatively large current, which will lead to too high battery temperature, a sharp drop in capacity and permanent damage to the battery core.

In fact, whether it is ordinary charging or fast charging, it will cause a little damage to the battery in the charging state, but this damage is very small, and it will only be shown on the mobile phone for a year or more at most.

Whether it is fast charging or ordinary charging, it will actually cause irreversible damage to the battery, but the damage of fast charging will be slightly stronger than that of ordinary charging. However, under the various guarantees of the current fast charging technology, the battery damage is still in a safe and reasonable state.

At present, most companies that provide fast charging solutions have not given the impact on battery life from the perspective of batteries, but according to national standards, the battery capacity is more than 80% qualified after charging and discharging for 500 times, which has little impact on the use within one year.
