Three things you must know about mobile phone charging

How to charge a mobile phone? This question can be said to be a topic that everyone has talked about in recent years. No matter how much teaching, no matter how many instructions are on the Internet, there are always many wrong teachings on mobile phone charging in society. These lessons include: the mobile phone must be charged for 8 hours before it can be used; the mobile phone must be completely powered off before it can be used; after the mobile phone is charged 90%, the charger must be unplugged. This teaching method surpasses the mobile phone, the electronics store, the Apple store and even TV news. So how do you charge your phone and how to maintain your phone battery? Today, I will sort out three things you must know about charging your phone. Just follow these three instructions to charge your appliances, and your phone battery will be more durable than others. First, lithium batteries have no memory effect. Excessive discharge will accelerate their death. According to my personal experience, recharging the mobile phone after it is used up is the number one mistake. Why is this misunderstanding? The battery memory effect, if it is not charged, it will damage the battery is one of the characteristics of Ni-MH rechargeable batteries, it is widely used in the mainstream rechargeable batteries before lithium batteries. 3 (as shown in the picture above) it will be completed only when the battery can be charged or the storage capacity of the battery will be more or less. But smart phones, tablet computers, notebook computers, digital cameras, mobile power supplies and other products now use lithium polymer batteries, which are commonly referred to as lithium batteries. This kind of battery has a very different characteristic from the Ni-MH battery: no memory effect, no over-discharge. The life of polymer lithium battery is calculated based on the number of charging cycles, that is, 0-100% of the number of charging cycles. 2. Don't rush to plug it in, leave it first and then unplug it. The second misunderstanding of charging is to unplug the power supply immediately after 100% charging. I personally do not know the source of this statement, but we should not explore the source of this misunderstanding. In fact, regardless of mobile phone or computer, the supplier will design an overcharging mechanism, when the battery will automatically switch to the computer or mobile phone power supply, as you can see in the above picture, for example, when the computer battery is charged to 100%, MacBookPro will automatically switch the power supply , It will remain in this state until the battery is 95%. If you are using iOS6 (if you are still using it), the power display in the upper right corner will also change to plug mode after charging, reminding you to switch to an external power supply. Keep the battery level below 40% every three to two weeks to stay healthy. If you successfully change your charging habits after reading the above instructions, and follow the above instructions to protect your battery, then you Long-life batteries have taken a big step. But you have to do one more thing: reduce the battery power to 40% every two weeks to stay healthy. First of all, we need to know that the lithium battery is a very long battery. If you let it charge and discharge continuously, it will hang up early, and always let it discharge to 0% will hang up early, even if you don’t always let it. Discharge will hang early! Due to the physical characteristics of lithium batteries, if the battery is not fully discharged for a long time, and the internal storage structure is activated, the battery will die prematurely. But if you let him discharge all the time every day, it will also allow the battery to die. In order to solve the contradictory problem, the best way is to make the battery less than 40% (30%, 0%) every two weeks without using rechargeable batteries. It can maintain the health of the battery very well, allowing him to accompany you for a long time! Of course, this is a requirement if you often plug in the appliance, if you can discharge the battery below 40% every day , Then there is no need to do such unnecessary things! When will the battery run out? This is not an explosion. This is just a mechanism to alert you that the battery is broken. If your iPhone or other device suddenly becomes fat, please replace the battery immediately. Second, if the battery is not getting fat, but your phone’s stored power is significantly less than before, then if you exclude the power usage peak that is not caused by your application, and you still run out of power soon, then Just fix it!
