Why does the phone automatically turn off when there is power, and then it will show that there is n

The automatic shutdown of the mobile phone is divided into two situations: normal automatic shutdown and abnormal automatic shutdown The so-called normal automatic shutdown refers to the exhaustion of electrical energy, 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 representation of the power inside, and the ICH value can be seen through the engineering mode 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 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. The leakage of the motherboard of the mobile phone causes the current to be too large.

2. The battery itself has aged.

3. There is dirt in the metal sheet at the contact point of the battery, resulting in poor contact of the power supply.

Hello dear, I'm happy to answer for you, what is the reason why the mobile phone is charged but always automatically turns off the stove 1Check whether the phone has enough power Keep the phone battery sufficient, the low battery of the phone will cause it to turn off automatically, it is recommended to charge it in time when the battery is about 20% left. 2.
