Some misunderstandings of cell phone lithium ion battery and charging
When using a mobile phone, do you find such a problem? After using the mobile phone for a period of time, the battery will become very unsatisfactory and the power consumption will be very fast. why? In addition to the slow development of cell phone lithium ion battery and the inability to change the capacity of these users, some of the bad habits of charging cell phone lithium ion battery on a daily basis are also the reasons for the serious decline in mobile phone life.
There have been a lot of talks about the charging of smartphone batteries, and some chargin g mistakes often make people confused. You should have heard this saying, "It's best to wait until the phone's power is fully used and then recharge it." "The longer the charging time, the better the battery." There are many similar statements. In order to enable everyone to use the phone more safely and effectively, let's take a look at some of the misunderstandings of the phone battery and charging.
1. Let the phone charge all night to reduce the battery life of the cell phone lithium ion battery?Currently, cell phone lithium ion battery are the first choice for most mobile phones because they have a battery overcharge protection mechanism. But we don't recommend charging you all night. In fact, lithium ion battery need to pay attention to the damage caused by over-discharge. The battery should be kept between 40% and 80%. Do not leave the battery in a low battery state.
For newly purchased mobile phones, there is no particular precaution for charging lithium batteries, because the current drops slowly when the new battery is charging, and the current may not fall to zero when it is full, so there is no need to worry about the voltage rising twice. The problem.
2. When the cell phone lithium ion battery is dead, recharge it?Today's mobile phones are equipped with cell phone lithium ion battery. There is no memory effect. If the phone is completely discharged and recharged, it will damage the chemical activity inside the cell phone lithium ion battery. After the iPhone is turned off, the recharge will not start immediately. It needs to be charged for a period of time before it can be turned on, just to protect the chemical activity inside the battery of the mobile phone. So, don't wait until the phone is out of power and then recharge it.
3 The more frequent the charging, the shorter the life of the cell phone lithium ion battery?Previously, it was widely believed that the lithium ion of a cell phone lithium ion battery would lose its vitality as the number of times of charging increased, thereby affecting the battery life. However, the iPhone official said that the life of a lithium battery depends on the charging cycle rather than the number of times. Generally, the life of a cell phone lithium ion battery can reach several hundred charge-discharge cycles. The charge-discharge cycle here refers to the process of charging the battery after it is used up, instead of plugging in the charger and then unplugging it once.
In terms of the iPhone's battery, the iPhone official said that after 500 cycles, the battery's power will be reduced to 80%. For the average user, it is usually about one and a half to two years.
