Is it harmful to the battery?


Now, fast charge is still a certain skill guarantee. Because the power processing module has preset the maximum voltage, current, temperature and other safety protection mechanisms of the phone battery in a set of fast charging plans, including temperature maintenance, short circuit maintenance, over discharge, over current, over voltage maintenance maintenance and many other protections Skill, to be precise, this fast charging technology is safer. Of course, since the current and voltage of fast charging are higher than normal state of charge, a failure to clean up is likely to cause some kind of risky event in the power handling module, but that's another story.

What is the difference between Qualcomm/OPPO/MediaTek?


Before we understand how battery charging works, trusted friends also understand a few things. From the principle, the harm of the battery comes from two fundamental aspects: on the one hand, when the battery is charged and discharged, the cathode and anode of the battery will follow the release and absorption of ions, shrink and expand, and fast charging will damage the battery for a long time. chemicals that cause shortened battery life. On the other hand, in the case of fast charging, due to the relatively large current, the thermal effect of the current will increase, resulting in an increase in the battery temperature, which will also lead to a sudden decrease in the battery capacity and permanent damage to the battery.


In fact, charging does a little damage to the battery, but the damage is so small that it can take a year or more to show up on the phone. So neither fast charging nor normal charging will reverse the damage to the battery, but fast charging will be slightly more harmful than normal charging. However, under the various guarantees of the current fast charging technology, the battery is still in a safe and reasonable state.


In general, considering that most phones these days don't replace batteries, for those who want to use it for a few years, it's probably best not to fast charge. For most people who change jobs every year, the effect is minimal.
