Fast charging of mobile phones can cause some damage to the battery, but to a relatively small extent. Fast charging technology provides high current and voltage during charging to accelerate the charging speed of the battery. This will accelerate the chemical reactions inside the battery, causing the temperature of the battery to rise, leading to some damage.
However, modern fast charging technology has taken some measures to reduce this damage. For example, by upgrading the fast charging chip and improving the charging management system, problems such as temperature rise and voltage fluctuation during battery charging can be reduced. In addition, during charging, the phone will also automatically control the current and voltage to ensure safety during battery charging.
Additionally, it should be noted that prolonged use of fast charging technology may shorten battery life. Therefore, in order to protect the battery, it is recommended not to use fast charging for a long time, and it is best to control it within 80% of the battery capacity. In addition, slow charging can also be used for charging, such as using a regular charger at night to spread the charging time over several hours.
In summary, fast charging technology causes relatively little damage to the battery, but it is still necessary to pay attention to protecting the battery. It is best not to use fast charging for a long time to ensure the battery's lifespan.
