Teach you to reduce battery consumption After reading the old phone, you can last another year

Every year after the release of the iPhone, there will be a wave of replacement, and one of the important reasons is that the old machine is not durable due to battery wear. In fact, the loss of the battery is not inevitable, as long as we pay attention to some details in use, we can make the battery last longer and help you save money on replacing the new machine. Today I will give you a popular science about why the battery capacity is reduced and how to extend the battery life.

Now smartphones mostly use lithium-polymer batteries, and its working principle is as simple as this:

There are positive and negative poles in the battery, in which the negative electrode has a large number of lithium ions in the graphite structure, this lithium ion is easier to lose electrons, and because the electrolyte in the middle does not allow electrons to pass through, a large number of electrons will flow through the mobile phone components to provide electricity, lithium ions will also flow to the left through the electrolyte, forming lithium cobalt oxide. When lithium ions flow to the positive electrode, there is no electron discharge at the negative electrode, and the mobile phone is out of power.

On the contrary, the adapter exerts a greater force on the electrons of the positive electrode, and the lithium ions return to the negative electrode and return to the state before discharge.

After understanding the principle of charging and discharging this battery, the reason for the battery capacity attenuation is also coming out:

1. Influence of working factors: when the discharge is too much, a large number of lithium ions in the negative electrode flow to the positive electrode, and the reaction forms irreversible lithium oxide and other substances, the overall lithium ions are reduced, and fewer electrons can be accommodated; The same goes for charging too much. Staying in a high temperature environment for a long time will also affect the chemical reaction inside the battery, the stability of SEI, and so on.

2. Internal factors: irreversible consumption of active materials inside the battery.

3. Influence of non-working factors: physical factors such as impact and needle puncture cause damage to the battery structure, resulting in explosion and other phenomena.

Based on these factors, Apple has also officially given several solutions to maintain the battery, and users who are interested in extending the service life of mobile phones can pay attention to:

1. It is recommended that the iPhone be charged between 30%-80% each time, and not overfilled.

2. The power of the mobile phone is about 20%-45% to charge in time, do not wait for the power to be too low to charge.

3. At least once a month for a complete cycle of charging, that is, wait until the mobile phone power is below 20% to start charging until it is fully charged, which is a cycle.

4. Avoid playing with the mobile phone during the charging process, which has a large loss of the battery and is risky.

5. If you charge overnight every day, turn on the "optimize battery charging" function, and the system will automatically slow down the charging speed when it is close to full and not overcharge.

6. Avoid charging the long-term battery below 20%, which will cause great damage to the battery.
