Attention of iPhone Battery Charging

There are many articles about iPhone charging tips, such as this one. Do not use the phone until it shut down before charge. But in daily use, there is still a lot of people have a myth: the iPhone used to shut down or power down before charge. This actually will damage the iPhone battery. What's going on here?

In the feature phone era, most phones used nickel-cadmium batteries. This kind of battery has memory effect. In the past, in order to avoid the generation of memory effect and the reduction of battery capacity, we used to charge the mobile phone battery after it was used up in the use of functional phones. When charging, the battery should be filled before use, which is commonly known as "full, full and put".

However, in the era of smart phones, the batteries used in mobile phones and digital products are lithium polymer batteries. Lithium battery itself has no memory effect, so it does not need to be filled as the original nickel-chromium and nickel-metal hydride batteries. On the contrary, if a mobile phone is kept in low or even out of power for a long time, it will only cause damage to the mobile phone and even cause the battery to lose its normal working ability in a short time.

Due to the characteristics of lithium battery itself, when the battery is out of power, the mobile phone will still have a small part of battery storage, the battery of lithium battery will be automatically consumed with time, after this small part of the battery is exhausted, the battery will automatically enter the deep discharge state, the battery activity will decline, over time will lead to the mobile phone can not be charged.

Some of you may have noticed that you can't turn on your iPhone right away when the battery is dead and you have to charge it again. Apple's design is also designed to avoid damaging the health of the phone's battery by working in low-power mode. However, some brands of mobile phones can still be turned on and used in case of emergency even when they are out of power. In fact, this will do great harm to the battery of mobile phones. However, after the iPhone is shut down, it is basically unable to be switched on for use, which is also to avoid the unnecessary loss of battery caused by the abnormal operation of users.

To sum up, we should try our best to avoid shutting down the iPhone when it runs out of battery power in daily use, so as to make our phone battery live for a long time and not wear out seriously too early.
