The phone is always turned off by itself, what s going on

There are two types of mobile phone automatic shutdown: normal automatic shutdown and abnormal automatic shutdown.

The so-called normal automatic shutdown means that the electric energy has been exhausted, and the observed ICH value is basically lower than 10 (standby operation 000000 * into the engineering mode, and then enter the load control to see the ICH value of the power inside, and the ICH value through the engineering mode can see that the normal full power is 92 or 93!). This 92 is not 92% of the actual charge, and understands it as a sign of the battery use phase! 92--90 can be used for more than 1 day, 89--60 can be used for more than 1 day, 59--15 can be used for more than half a day, and 10 or less will be automatically shut down), in this case, the automatic shutdown is normal.

If the power is sufficient but suddenly shuts down during use (especially during a call or text), the battery will be displayed as a sufficient symbol after powering on. This phenomenon is an abnormal shutdown, and it is also manifested as a standby everything is almost normal, once calling, texting, GPRS, and taking pictures will automatically shut down, in other words, it will work normally when the current signal is weak, and turn off immediately when the current is large. Many users have experienced sudden automatic shutdown, and the reasons for this are as follows:

1. The leakage of the motherboard of the mobile phone causes the current to be too large.

2. The protection circuit in the lithium battery is overly sensitive, so the current will be cut off when the current is large.

3. The battery itself has aged.

4. There is dirt on the metal sheet in the contact position of the battery, which causes poor contact with the power supply.

5. The joint between the battery and the mobile phone is easy to loosen.

If after the inspection, it is found that the first two problems are the first two problems, if it is within the warranty period, go to KF, and after the warranty period, then find a good reputation of a special repair shop to repair. If the latter two problems are caused by the oxidation of the dirty metal sheet of the battery, the situation will be improved as long as it is wiped clean with a glue stick. Putting paper or film between the battery and the phone can also solve the problem of poor contact caused by loose batteries.

1. No power or battery quality problems.

2. The system is unstable, and the system is re-brushed.

3.The software is unstable, try to clear all data. But back up your data.

If it's not a battery problem, please flash it again and change it to a stable ROM If you have any questions, you can continue to ask me

The first situation may be that the battery is loose, confirm whether the contact between the battery and the mobile phone battery connector is reliable and normal. If it is found to be loose, there is a hidden danger that will lead to automatic shutdown. You can improve the contact between the two by adding a "pad", which is simply to squeeze the battery tightly and don't let it shake casually.

The second is that there is a problem with the battery itself, and the link between the nickel strip or protection plate and the battery cell inside the battery has virtual welding or poor contact, which will also lead to unstable power supply and automatic shutdown. In this case, it is best to go to a phone repair shop to replace a battery.

The third is that there is a problem with the motherboard of the mobile phone, usually there is a problem with the CPU, memory or power management, resulting in an unstable power supply, which needs to be repaired at this time. If you don't have the expiration date of the mobile phone battery, you can go to the mobile phone store to repair it.

The fourth is the software problem, what virus software may have been downloaded, the next mobile phone manager will take a look, and then uninstall it.

It's basically these kinds of questions, I hope it helps you, hope, thank you!

If it's not draining too much power, it could be a faulty motherboard circuit. If you are not professional, it is recommended to find an after-sales maintenance department for inspection and maintenance.

1. Check your phone's battery.

As we all know, when your phone has been used for some time, there will be some problems with the battery. So, if your phone turns off automatically, then you should hurry up and check if there is some problem with the battery. For example:

See if there are any phenomena such as aging and bulging in the battery; Or see if there is some loosening in every contact between the phone's batteries. If you know that the automatic shutdown is a problem with the battery, you can take it to the phone store to have it repaired, or buy a new one.

2. Conduct a security scan of your phone.

In many cases, without our knowledge, your mobile phone is likely to be planted with some viruses or Trojans, and it is possible that it will often shut down automatically. At this time, the most correct solution is: you need to open the most secure software on your mobile phone, conduct a complete scan of the mobile phone, and if there is a Trojan horse or a virus, you must immediately check and kill it.

3. Check the mobile phone software.

Needless to say, each brand of mobile phone has its own set software capacity. Therefore, if there is too much software in your phone, or there is a conflict in your software, it will cause your phone to shut down automatically. At this time, the most correct thing to do is to uninstall some unnecessary software from your phone to speed it up.

Fourth, the problem of flashing mobile phones.

Normally, although flashing the phone can let us know more about its functions and permissions, but at the same time, our mobile phone system may also have some small failures, resulting in your mobile phone often automatically shutting down. However, if you are 100% sure that your phone is due to a problem with your own flashing, just press restore to the original factory settings, and all the problems will be solved!

Fifth, there is a fault in the mobile phone.

If after your own testing, the automatic shutdown of your mobile phone is not caused by the above reasons, then you can personally take your mobile phone back to the mobile phone service center for testing to see where the problem is. If it is a problem with your phone, then you can ask the repairman to help you fix it, so that the problem of your phone automatically shutting down is solved.

If you are using a vivo phone, you can check the following processing methods:

1. If you have recently installed the software through non-app store channels, it is recommended to uninstall such software and try it. If the program keeps reporting errors, restarting, or fails to boot normally, you can enter safe mode and uninstall the previously installed software to troubleshoot. Safe Mode Entry Exit Method:

During the device boot process, release the power button when the screen displays the vivo nex iQOO logo, wait for about 5 seconds, and then press and hold the "Volume Down button" immediately, and do not release the button before entering the lock screen to enter safe mode. When the operation is complete, restart the device to exit safe mode.

Note: The operation of uninstalling the software will delete the software data, please pay attention to back up the data.

2. Insufficient storage space may cause the device to restart automatically, please enter iButler and free up space through "Space Cleanup" to ensure that the storage space is sufficient.

3. If the above methods cannot be solved, please back up the important data on your mobile phone in advance, and bring your mobile phone to the vivo customer service center for testing and processing.

Go and select your current city to get it.

Tips: It is recommended to bring relevant purchase vouchers (such as: purchase invoice, warranty card, ID card) when you go, and consult the staff of the consulting center in advance to ensure that the staff go again during normal working hours, avoid empty running, and pay attention to safety on the way to and from the service.

Precautions for the use of the equipment:

1. Try to avoid using the equipment in low temperature, high temperature or large temperature difference environment. The device has a built-in temperature protection function, if the temperature is too low, it may trigger low temperature protection, if the temperature is too high, it may trigger thermal protection, and when the temperature is too low or too high, it will automatically shut down or restart.

2. Make sure the device has enough power, and the device will automatically shut down when the power is insufficient.

3. Check whether the buttons of the device are stuck (such as the keys of the protective case and other objects), because pressing and holding the power button and the volume down button for more than 10 seconds at the same time will trigger a forced restart.

4. Check whether the device is set to switch on and off at a timer (enter the settings, search and enter the "timer switch") If the function of switching on and off at a timer is set, the device will automatically turn on and off at a specific time.

5. If the equipment is damaged or liquid ingress will cause unstable operation, you need to bring the equipment to the vivo customer service center for further testing.

The phone keeps shutting down on its own is a battery or system issue.

The phone keeps shutting down for no reason, it could be due to a damaged battery, or something wrong with the system. In Settings, tap into Battery and see if the word Needs Service appears. For system issues, click General in Settings and select the Restore option.

Tap Erase All Content and Settings in the category and enter the passcode to restore factory settings.
