The phone still has 70 battery and always turns off automatically

There are two scenarios for the phone to automatically turn off:

Normal auto-shutdown and non-normal auto-shutdown.

The so-called normal automatic shutdown means that the power has been exhausted, and the observed ICH value is basically lower than 10 (standby operation 000000 * into engineering mode, and then enter load

control looks at the ICH value that characterizes the power inside, and looks at the ICH value through the engineering mode to see that the full power is 92 or 93 under normal conditions. 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 the sudden automatic shutdown for several possible reasons:

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.

First, check if your phone is set to power off automatically.

Then turn off the phone when charging next time, and turn it on again when it is fully charged, and adjust the phone battery.

If it doesn't work, it's a problem with the battery.

Summary. 1.The phone is turned off when it is still 30% charged, because the phone's battery is virtual.

2.Virtual power means that the battery has always been in a semi-active state that is semi-charged, a simple understanding of the battery's display power display is very high, the actual is relatively low, not the real power of the battery, the battery is charged for a short time and there is a lot of or full power, but it is quickly used up.

3.For such a battery, it must be trickled up when in use, and you can wait for more than half an hour to pull it out after it is fully charged, if it still doesn't work, replace the mobile phone battery.

The mobile phone still has more than 30% of the battery, what happens when the mobile phone turns off automatically?

My phone battery is new and half a month.

It's the new battery that's wrong. After Apple replaces the battery, there may be fast power consumption, serious power failure, and hot mobile phone, these situations are because the mobile phone battery has just been replaced, and the CPU will be unsuitable for a short time, and it needs to become normal after multiple charging and discharging. You can first see if the battery is installed correctly, the installation is no problem, the big problem is the battery itself.

Summary. Hello dear, glad to answer for you. Pro, 1

6.Uninstall incompatible softwareInstalling some incompatible software through non-HUAWEI AppGallery channels may also cause your mobile phone to shut down or restart, so we recommend that you back up the app (WeChat QQ and other apps need to be backed up separately), and then uninstall the software installed on the non-HUAWEI AppGallery** before attempting.

The mobile phone is still 60% charged and turned off, which is normally a battery problem, which is aging and needs to be replaced.

The mobile phone still has more than 30% of the battery, what happens when the mobile phone turns off automatically?

Many users have experienced the sudden automatic shutdown for the following reasons: 1. The leakage of the mobile phone motherboard causes excessive current. 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.

Most of them are battery issues, but there are also software issues.

The old phone got up this morning and saw that it was turned off, and there was still 70% power after turning it on, why did it suddenly turn off, solve?

There can be many reasons why your phone shuts down suddenly, and here are some possible reasons:1Battery life:

If your phone's battery is aging, it may turn off suddenly, the battery aging will cause the phone's battery level to be displayed inaccurately, and the remaining power is higher than the actual power, and the phone may suddenly shut down because the battery level is emptied. 2.Overheating:

If your phone overheats while in use, the overheating protection mechanism may cause the phone to automatically shut down to avoid further damage, the main reason for which may be prolonged use or use in the charging hall. 3.Power Management:

Some phones will automatically turn on the power management mode to improve battery life, and if the mode has been on for more than a certain amount of time, it will automatically turn off. 4.Software Issues:

Some apps may consume a lot of battery or run time, causing the phone to shut down suddenly. Or when you have just updated or upgraded an app or system, there may be some programs that have problems causing your phone to shut down automatically. 5.

Hardware problems: If there is a problem with the remaining parts of your phone, such as memory damage, power supply damage, etc., it may also cause the phone to shut down suddenly. If there is an abnormal situation before your phone is turned off, such as rapid battery drop, overheating, etc., you can first cool down the phone, close some power-hungry apps, restart the system and try to eliminate the problem, if it still can't be solved, it is recommended that you go to a professional mobile phone repair shop for help.

At the same time, in order to prevent similar problems from happening again, it is recommended that you perform regular maintenance on your phone, such as cleaning your phone.
