How to solve the problem that iphone7 can t be charged

iPhone7 mobile phone does not charge is generally caused by the following reasons:

1. System software failure.

2. Always use a high-imitation charger.

And. Cable charging.

4. The iPhone fell due to bumps.

Or. Prolonged water ingress.

The above reasons may cause iphone7 to not charge, first troubleshoot the system software failure problem:

1. Force restart, press the power button + volume down button for 10 seconds, until the Apple icon appears, and then you can let go.

2. If there is no response, plug in the power supply to charge the iPhone and try to restart it again. Until the apple icon appears.

3. If there is no response, try to flash the phone, but you must remember the ID and password to operate, otherwise the iPhone will become a brick.

If the above methods cannot be solved, it is usually the motherboard.

And. The failure of the battery, some components on the motherboard are heated, bumped and dropped for a long time, or water ingress, resulting in short circuit, leakage, high current, etc. This can be done through constant current value detection and chip transplantation.

The repair method of repair welding is as follows:

1. By detecting whether the constant current value on the motherboard is abnormal, such as abnormality, it proves that a certain or some components on the motherboard are caused by short circuit.

2. Take the lavender rosin method to test which component of the motherboard is too high, which can be seen by visual inspection.

3. After determining the specific short-circuited components, replace the short-circuited components through value shifting and welding technology.

4. Press the power button again to boot the test.

If it can be turned on, the problem is solved. Otherwise, there are still other short circuits, and the above steps must be repeated.

iphone7 charging does not power repair example.

1. The solution to iphone7 can't be charged, before encountering a problem, the first thing you should do is to find the cause of the problem.

2. Charger reason: If you use an old-fashioned charger, due to insufficient power, it will cause slow charging speed or even unable to charge. At this time, it is necessary to replace the charger, and it is recommended to buy the original Apple charger.

3. Charging cable: Check whether there is a problem with the charging cable, try to use the original charging cable to charge the device, and do not use the charging cable indiscriminately or mix it.

4. Charging temperature: Apple's devices generally have a low-temperature protection function, and if the temperature is too low, it will not only fail to turn on, but also cannot be charged. If you find that the charging is slow when using iphone7 in winter, you can try to warm up the phone for a while before charging. In the north, special attention must be taken.

5. Software failure: If it still can't be charged, then press and hold the power button, and then a prompt to slide to the right to shut down will appear, shut down, charge after shutdown, and see if it can be charged, if it can be charged in the shutdown state, it is a software failure.

6. iPhone7 mobile phone is broken, one of the most serious reasons, if the above methods cannot be solved, please go to Apple's official store as soon as possible for testing.

The iOS system is not good enough in terms of fluency, and many fruit fans joke that as long as the iOS system is updated, the fluency of the iPhone plummets. Last year, the iPhone was exposed to the "frequency reduction gate" incident, which made many people feel very angry, and at the same time, everyone's desire for system updates is getting smaller and smaller.

What should I do if there is no way to charge my iPhone?

1. The battery is excessively worn out and has been completely damaged.

Generally speaking, this situation is relatively rare, and it is normal for a normal iPhone to have a battery health of more than 85% within one year and more than 75% within two years. But if you use it for a year and it has dropped by 80%, there are only two possibilities, one is that you have bought a fake, and the other is that you have often committed the behavior mentioned in the previous section to damage the battery. I've seen people who charge their batteries almost several times a day because of playing card games, but in less than half a year, the battery health of their mobile phones has dropped to 78%.

2. The battery management IC is damaged.

In this case, most of the reasons are that the motherboard components are desoldered due to the mobile phone falling to the ground, and the probability is very small. If the battery can't be charged and the motherboard is damaged, the store will charge you more than 500 so-called motherboard replacement fees, but in fact, you only need to replace the power supply IC for more than 100.

3. Non-original charger, the charging cable is damaged.

This is easy to do, ask someone for an original iPhone charger and charging cable to try it.

4. Mobile phone system failure.

Press the power button + home button at the same time until the Apple logo appears, force restart the iPhone, it should be solved.

5. The gold finger of the charging port is oxidized or dirty.

Use the SIM card pin that comes with the iPhone to scratch the gold finger part of the charging port on the iPhone, and try to scrape off some oxides on it (generally this problem is definitely an old iPhone that has been used for more than 1-2 years).

If the phone can't be charged, the battery may be broken or the charger is broken, you can try to replace the battery and charger.
