I often have friends and me spit out, saying that my mobile phone is getting less and less durable, so I asked about it. It turned out that although the smartphone has been in existence for more than 10 years, many people still charge the charging method, and some take it for granted. The practice is even "harming" your own mobile phone battery, there are 3 wrong charging methods you may also make mistakes.
First of all, the popularity of a small knowledge is that today's mobile phones and laptops use lithium-ion batteries instead of nickel-metal hydride/nickel-chromium batteries, so many ancient “charging cheats” have long been inapplicable if you are wrong. Three things, then it is likely to cause the battery to be not durable.
01 charging three times to activate? Can't believe it!
In the early days of Nokia's dominance, there was a rumor that the battery of the new phone needs to be fully charged and discharged three times to activate the full capacity of the battery, even if it is better to charge 12 hours. In fact, this rumor is wrong.
Regardless of the phone or laptop, the memory effect of the built-in lithium-ion battery is negligible, even negligible, so there is no need for three full charge and discharge to perform the so-called activation.
02 exhausted power and recharge? No need!
Many people like to charge the battery after a small amount of power, so that it can be used more battery life, in fact, this is not necessary.
Because the memory effect of the lithium battery has little effect, it does not need to be completely discharged to maintain the battery performance, and the deep discharge will affect the performance of the lithium ion in the battery, and the power is often exhausted, which is not conducive to long-term use.
03 Frequent charging loss? does not exist!
Everyone knows that batteries have a cycle life, but most of you don't know how life is calculated. Many people don't dare to charge frequently, thinking that they will reduce the cycle once they are charged. In fact, such an algorithm is wrong.
The cycle life of a lithium battery refers to the fact that the discharge capacity reaches the rated capacity once. If it is charged with 10% of the power every time, it will be charged 10 times to consume the cycle life.
Here we have another knowledge, that is, the lithium-ion battery used in mobile phones and computers can have a cycle life of more than 500 times, and 500 times here is not what most people understand. High-quality batteries can still be provided after 500 cycles. Design a capacity of 80% of the capacity.
Therefore, when charging mobile phones and notebooks, there is no need to worry about the cycle life, but to avoid the effects of frequent overcharging or over-discharging on the battery, making the mobile phone battery more durable. When using a mobile phone, you can charge it as long as you think that the battery is low. In addition, you can avoid unnecessary trouble caused by power failure by keeping the battery in a timely manner.
