Since the "universal charge" was replaced, the battery in the mobile phone as a consumable has gradually been concerned by us. Many people will charge their mobile phones all night for the convenience of going to work the next day, so is it harmful to the battery?
First of all, we have to understand the charging process of the mobile phone battery.
In the eyes of ordinary people, mobile phone charging is the process of the number of electricity from 0% to 100%, but this is not the case inside the mobile phone.
If your mobile phone has more than ten percent of battery power left, when your mobile phone is connected to the charger, the charger will use a constant current for fast charging for a period of time, and you will find that the charging speed is particularly fast at this stage.
Mobile phone battery charging process
When the battery is charged to 60%, the charger will gradually reduce the current. When the power is charged to 80% or 90%, the charger will use trickle to charge, which is also to protect the life of the lithium battery. This is why everyone thinks that Apple phones and Huawei phones charge very slowly after charging to 90%. When the battery is fully charged, the phone will recharge according to the released battery.
Apple's official website's recommendations for charging lithium batteries
This is the whole process of battery charging, including the current 120W and 200W fast charging principles, but they will use a higher current during the fast charging phase.
In fact, the current power IC management is very mature, so even if the mobile phone is charged for a whole night, it will not cause any harm to the battery.
The following behaviors are really bad for the battery!
Use fast charge
Now every mobile phone uses fast charging. I still say this here. Isn’t it alarmist?
But you will find that although many mobile phone manufacturers already have 120W fast charging and 200W fast charging technologies, they have not popularized them. Most mobile phones still use 66W fast charging, and even Apple still insists on using 20W fast charging. People's Daily Online also criticized Xiaomi's 200W fast charge.
One of the reasons for this is that although the numbers of "120W" and "200W" are getting larger and larger, in fact, only a small part of the "fast charging" phase of the mobile phone will use such a large amount of power during the charging process. More used is trickle charging. Therefore, People's Daily Online is also criticizing Xiaomi for blindly pursuing high power, and we should find ways to extend the "fast charging" process. If the "quick charge" process can be fully extended, in fact, a 50W quick charge is enough for us to use.
In addition, mobile phone lithium batteries will also accelerate battery loss due to fast charging. There is a Mi 10 Extreme Edition used by a friend around the author. After using it for almost a year, his battery health has been depleted to 87%. The usable capacity of the battery has lost 563 mA, leaving 3927 mA. Play while charging
Want the horse to run again, but don't feed the horse?
Many friends who love to play games still insist on "opening black" with their friends when their phones are out of power, so they choose to play games while charging.
But unlike a laptop, a mobile phone can directly power the laptop with a charger. The charger needs to charge the battery into the battery before it can be used by the phone. When the mobile phone is playing games, it consumes a lot of power, which causes rapid charging and discharging, which affects the life of the battery.
How to better protect the battery?
If your replacement cycle is within two years, you can actually build it with strength. You can play while charging, and you can choose high-power fast charging. After two years, the battery will not be consumed too much, and it will die by about 20%, which can maintain daily use.
But if you want to use your phone longer, then you should pay attention to how to use it well. Otherwise, the battery will be consumed too much at that time, which will affect your normal use, which will cost hundreds of yuan or even hundreds of yuan to replace the battery.
According to the activity characteristics of lithium batteries, the best way to charge lithium batteries is to start charging when there are 20% remaining, because over-discharge will affect the activity of lithium batteries. If you rarely use your mobile phone, it is best to start charging when the battery is 80%, because trickle charging has the least loss of battery, but most people will not charge when the battery is 80%.
For the general public, the healthiest way to charge mobile phone batteries is to use more and more, that is, charge it when nothing happens, and use the mobile phone as long as you want, keeping the power in the range of 50% to 90%.
