Why did the mobile phone run out of electricity all at once?

Maybe the battery is finished, it is recommended to have a new battery.

There must be a problem with the battery.

There could be three reasons for this:

1. The boot itself is more power-consuming, and the more programs you start at boot, the more power you consume.

Second, there is a small bug in the power management software of this mobile phone, and the display of battery power is not refreshed in time after the power is reduced.

3. If the battery is used for too long, it will be charged with virtual electricity.

Solution: The first two reasons do not affect the use of the mobile phone; If this situation often occurs, it may be the third reason, if you care about this, you can replace the battery, if you don't care, it doesn't have much impact, just pay more attention to charging.

Mobile phone charging, charge for a while, occasionally this has little impact on the mobile phone, the number of charging times of the mobile phone is regulated, more than or close to the number of charging times, the battery is basically scrapped, so when you charge for a while, it is equal to again and again, which will affect the life of the battery. In fact, from the perspective of long-term battery storage, the battery should not be fully charged. After the battery is fully charged, a large voltage will be generated inside it, and there is a possibility that excessive air will be generated due to the chemical reaction inside, causing the battery to bulge.

So if it is an old mobile phone that has been replaced, it is best not to store it after it is fully charged, and it is generally enough to charge it to about 90%.

In addition, in the process of using the mobile phone, it is best not to wait for the power to be consumed, and the mobile phone will automatically shut down before charging it. Because if the mobile phone battery is over-discharged, its electrode active material is damaged and loses its ability to react. In severe cases, it will also cause permanent damage to the positive and negative electrodes of lithium batteries.

So when the phone battery is less than 20%, it is time to plug it into a charger.

Finally, mobile phone batteries are also sensitive to temperature, usually with large attenuation in environments below 10 and excessive discharges in environments above 35. If you want to extend the life of your phone, it's best to avoid using your phone in an environment that is too cold and too hot.

First, we must determine how long the mobile phone battery has been used, the normal use time of the general mobile phone battery is 2 3 years, and secondly, whether the life comes in advance, the general lithium battery can be charged and discharged about 500 times, and the battery life will of course be used up in advance.

Second, we should also pay attention to the capacity of the battery, some mobile phones consume a lot of power, and the small capacity battery is of course used quickly.

Fourth, the temperature is too high or too low, which will also affect the battery storage capacity.

Fifth, the charger is also broken.

The battery contacts are dirty, just scrape them clean with a blade. In addition, do you charge with direct charging or universal charging?

It's no wonder that the phone runs out of battery as soon as you use it, and after reading these 5 misunderstandings about mobile phone charging, I finally understand.

If the mobile phone consumes a lot of power, it is necessary to find the reason for the fast power consumption and take corresponding measures according to different reasons.

1. The brightness of the screen is too high.

A screen that is too bright will speed up power consumption, so dim the screen a little bit, and if the phone's function allows, you can set the brightness of the screen to automatic, or set it to eye protection mode. It can be automatically brightened or darkened with the surrounding environment. Too bright a screen will have an impact on your eyesight, so you need to be careful.

Second, the mobile phone wifi is turned on for a long time.

If the wifi is on for a long time, the phone will constantly search for the wifi signal, which will consume a lot of power. If you are on the road or in an unfamiliar place, please turn off the wifi connection, which not only saves power but also makes it safer.

3. Mobile phone notifications are turned on for a long time.

The constant notification and message bombardment of your phone will also accelerate the battery drain, so please turn off some inconsequential notifications in "Settings - Notification Center" to make sure that only the app notifications you really need are turned on. This not only saves power, but also avoids interruptions.

Fourth, the application runs in the background.

For programs that you don't need for the time being, it's best to turn off background running. Find "Apps" in the "Settings" of your phone, tap the app icon to open the settings page, and click "Force Stop". If you have an emergency where your phone is running low on battery, you may want to try this.
