iPhone is used to shut down and recharge, the damage is bigger than you think

Smartphone batteries have become the biggest pain point for users, and mobile phone manufacturers are looking for ways to alleviate the lack of battery life, but with little success. As a user, while we hope that R&D institutions will solve this problem as soon as possible, we must also pay attention to some methods for charging and using mobile phones, so as not to make the already stretched mobile phone life ability even worse. In all articles about iPhone charging skills, there is an article that does not use the phone to turn it off for charging. However, we still see a lot of iPhone users, especially older users, will habitually use the phone until it is turned off or when it is about to run out of power to charge. This is also due to the memory effect of nickel-chromium and nickel-metal hydride batteries used in mobile phone batteries in the era of functional machines.

The memory effect is an effect of the battery content crystallizing due to the use of the battery. Generally, only nickel-cadmium batteries occur, nickel-metal hydride batteries are less, and lithium batteries do not have this phenomenon. The reason for this is due to the incomplete charging and discharge of repeated parts of the battery. Will reduce the battery's temporary capacity, resulting in a shorter service life.

Therefore, in the past, in order to avoid the memory effect, the battery capacity is reduced. When we use the function machine, we will use the mobile phone battery to charge it. When charging, we should also use it when it is fully charged, which is commonly known as “full charge”.

However, in the era of smart phones, batteries for mobile phones and digital products use lithium-polymer batteries. Lithium-ion batteries have no memory effect themselves, so they do not need to be full of nickel-chromium and nickel-metal hydride batteries. On the contrary, keeping the mobile phone in a state of low power or even no power for a long time will only cause damage to the mobile phone, and it will also cause the battery to lose its normal ability to work in a short period of time.

Due to the characteristics of the lithium battery itself, when the battery does not have power, the phone will still have a small part of the power storage, and the battery's power will be automatically consumed over time. After this small part of the battery is depleted, the battery will automatically enter deep discharge. state, Battery activity will also decline, and over time, the phone will not be able to charge.

Previously, WeChat's readers 'friends had no power for several days due to data wire damage. After buying new data lines, they found that the charging of the mobile phone was much slower than before. The reason is that the mobile phone has not had power for a long time. After shutting down, the battery enters a deep discharge state, which causes the battery's activity to decline. The solution is to reboot the phone and recharge it back to normal when the battery is recharged to more than 20 %.

Some friends may have discovered that if the battery is exhausted and the iPhone is recharged after the phone is turned off, it can not be turned on immediately. When the battery is recharged by about 10 %, it can be turned on normally. Apple's design is also designed to prevent cell phones from working in low power mode and damaging battery health. And some brands of mobile phones can still turn on and off after the power is turned off. In fact, this does a great deal of damage to mobile phone batteries. After the iPhone is turned off, it is basically impossible to reboot it. This is also to avoid the user's abnormal operation leading to unnecessary battery loss.

To sum up, when we use the mobile phone on a daily basis, we must try to avoid charging the cell phone battery after it has run out of power. We can charge it at any time and stop charging at any time. Do not have any scruples. This is the biggest advantage of lithium batteries. Face this advantage, and play it, is the correct way to maintain the battery.
