1. Battery depletion

With the development of chip technology, the performance of smartphones has improved by leaps and bounds, and is comparable to that of computers in the past. It can not only make calls, listen to music and watch videos, but also surf the Internet and play games. With so many functions, people can't put it down, but also consume the battery quickly. When we forget to recharge the phone and the battery is exhausted, the phone will not turn on.

In this situation, the first thing to do is to charge your phone. If conditions permit, try to use the original fast charger to charge your phone. If there is no direct charging condition outside, please use a power bank that supports fast charging to charge. After charging for about 10 minutes, you can try to press the power button to turn on the phone.

2. The phone accidentally gets soaked in water

If you walk by the river often, you will get your feet wet. If you use your smartphone frequently, it is inevitable that your phone will get wet accidentally. Since the phone is an electronic device with a battery installed inside, water ingress will cause a short circuit in the circuit. In the worst case, the phone will shut down immediately, and in the worst case, the phone will die completely. Of course, the phone design itself has a certain degree of waterproof ability, so we still have a chance to save ourselves.

In this situation, the first thing to do is to wipe off the remaining moisture on the phone with absorbent cotton cloth or paper towels. If the phone battery can be separated, it is recommended to separate the battery first. Of course, for current mobile phones, consumers generally cannot separate the battery and need to go to a repair shop to separate the battery. The second thing to do is to use a hair dryer to blow on the phone to speed up the evaporation of the moisture in the phone. It should be noted here that cold air should be used as much as possible. Hot air is not good for circuit boards. Finally, place the phone in a dry rice jar and let it stand for 2 days to ensure that the phone is completely dry before turning it on and trying again.

3. The phone accidentally falls

It is common for mobile phones to fall accidentally. If the falling place is on soft grass, it is not a big deal. If it falls on hard ground, the mobile phone will basically have some damage, and of course it is possible that the mobile phone cannot be turned on. In this case, there are generally three types of damage that cause the inability to turn on.

Broken screen: After the screen is broken, although the machine can be turned on internally, because the screen does not display, people will mistakenly think that the phone is damaged. In fact, it may be repaired by taking it to a repair station and replacing the screen.

Broken circuit board: If the circuit board inside the phone is broken, the phone is basically scrapped. If only the internal circuit is detached, you can still take it to a repair shop for repair.

The battery is broken: In this case, you can basically just replace the battery. However, the probability of a battery being broken is actually very low, and it is usually accompanied by damage to other components.

If your phone is broken, you basically need to take it to a repair shop for inspection. If the repair cost is too high, just replace the phone; if the repair cost is low, you can still consider repairing it.

4. The phone becomes bricked after flashing

In recent years, fewer people have flashed their phones. In the early years, there were many enthusiasts who liked to play with their phones and they often flashed the system. Sometimes, if you are not careful, your phone will be bricked. In this case, you usually download a special ROM to recover the phone, force a double clear, and then flash it to recover the phone. Detailed tutorials can be searched in the online flashing forum, where you can find methods to recover the phone for specific models. Flashing is not recommended for those who are not very technical.

Summarize

There are generally four situations where a mobile phone cannot be turned on. We can use specific solutions to solve the problem according to the cause. Except for hardware damage, there is basically a chance to fix it yourself.
