The phone will automatically turn off and turn on again, what is the problem, what should I do?

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.

Battery problems! The battery is more seriously de-energized! Replace the battery!
