1. Mobile phone performance improvement
The performance of mobile phone hardware is constantly improving, and the exponential increase in performance also means that the mobile phone needs to consume more power when running. In addition, the increasing screen size and resolution of mobile phones is also a development trend, and high-resolution and large-size screens are also large power consumers.
2. Enhancement of mobile phone functions and the opening of Android system
With the improvement of mobile phone performance, the basic functions of mobile phones are also becoming more and more powerful. WLAN, Bluetooth, high-speed mobile network, various game application software, and watching online videos and playing games on mobile phones will significantly increase the power consumption of mobile phones.
In addition, due to the openness of the Android system, all kinds of APPs with uneven quality can also take advantage of the situation and try to induce users to install them. This kind of junk software is also one of the culprits of the power consumption of mobile phones. Pursuing indicators such as activity and user volume, let the application keep some malicious processes in the background, frequently start automatically or stay in the background for a long time to run, resulting in power loss without users noticing. The Android system can start multiple tasks at the same time and keep multiple tasks running in the background. During use, if the background programs are not closed in time, multiple background programs will run at the same time, and the power consumption of the mobile phone chip will increase during the continuous operation. Big.
3. Increased reliance on mobile phones
At present, people's dependence on mobile phones is getting higher and higher, and the frequency and intensity of using mobile phones are also getting higher and higher. We will continue to play games, watch videos, and use several chat software to chat at the same time. These are difficult in the era of feature phones. imagination. In our daily life, we use mobile phones frequently, and the power consumption will naturally increase as the frequency of use increases.

In summer, the weather is hot, the ambient temperature is high, and the mobile phone is difficult to dissipate heat. Therefore, compared with winter when the ambient temperature is low, the charging speed will be relatively slow, which is a normal phenomenon. Solution:
1. Wait for the temperature of the phone to drop before charging.
2. It is recommended to close the applications running in the background when charging to avoid the temperature rise when the power consumption of the mobile phone is high.
3. It is recommended that the ambient temperature during charging be below 30 degrees, or the mobile phone should be charged in a room with an air conditioner turned on.

If there is an icon for charging and the battery power does not increase or decrease, please check whether the mobile phone is connected to the computer for charging, because the output current of the USB interface of the computer is very small and unstable. If the mobile phone system is running applications with high power consumption, the small input current flow cannot be offset. The power consumed by the phone ultimately results in no increase in power. In addition, the abnormal charger will also have similar problems.
1. Please check whether the phone is charged normally when not in use.
2. Please use the standard charger to charge the mobile phone, and avoid using the computer USB interface or devices with low output current to charge the mobile phone.
3. Please upgrade the system to the latest version, uninstall the high-power-consuming applications in the mobile phone, clean the background applications of the mobile phone before charging, or restore the mobile phone to the factory to solve the problem.
4. If the charger is turned off and the charging is still abnormal, the charger may be faulty. It is recommended to replace the charger.
If it still can't be solved, please back up your data in advance and go to the after-sales outlet for maintenance with your purchase certificate.

1. If you can't power on the first time:
Maybe your phone battery has been discharged, please charge the battery for half an hour before turning it on. When the system is turned on for the first time, the system is initialized. It is normal for the system to start slowly. Please wait patiently.
2. If you cannot boot after factory reset or system upgrade:
1) After the upgrade is completed, it will require many system resources to be initialized, which will take longer than normal booting. This is a normal phenomenon. Please wait patiently. Please wait for more than 10 minutes to see if you can enter the system.
2) If you still cannot enter the system after waiting, please press and hold the power button for about 10 seconds to force restart the phone. If it can be turned on normally after restarting, it is recommended that you continue to use the phone, and pay attention to whether the phone system will be abnormal in subsequent use.
3) If you still cannot enter the system normally after forced restart, try to press and hold the volume down button + power button at the same time to check whether you can enter the recovery mode, and select Wipe data/factory reset, and Wipe cache partition. After resetting the phone, check whether it can be turned on normally.
1) Please make sure your phone is fully charged. When the power of the phone is exhausted, it may not be able to turn on immediately when it is just plugged into the charger. Please continue charging for a while before trying to turn it on.
2) Too many self-start items will cause slow startup, which will be mistaken for normal startup. Please prohibit unnecessary startup applications.
3) If you still cannot enter the system normally after forced restart, try to press and hold the volume down button + power button at the same time to check whether you can enter the recovery mode, and select Wipe data/factory reset, and Wipe cache partition. After resetting the phone, check whether it can be turned on normally.

When the phone automatically shuts down, please follow the steps below to troubleshoot:
1. Please confirm the battery level of the mobile phone first, the mobile phone will automatically shut down when the battery is low.
2. Please confirm whether you touch the power button by mistake. Press and hold the power button for more than 10 seconds, the phone will automatically shut down and restart.
1. If the ambient temperature of your mobile phone is too low, the chemical activity of the battery may deteriorate, the battery may not be durable, and it is easy to automatically shut down when the battery is low.
2. Overheating of the phone may also cause automatic shutdown. The mobile phone has a built-in thermal protection function. After using a high-load program for a period of time, if the temperature of the motherboard is higher than a certain level, it will automatically shut down.
If the above problems do not exist, please try the following solutions:
1. If high power consumption (above 30%) frequently occurs in high power consumption scenarios such as taking pictures, making calls, and games, it is recommended to go to the outlet to check whether the battery is aging.
2. If it also occurs in low power consumption scenarios, it is recommended to completely empty the battery and then recharge it for 3~5 times to confirm whether there is a similar problem when the power display is accurate. If there is still a similar problem, it is recommended to Site overhaul.

Reasons for slow charging when the phone is almost fully charged:
1. Usually, the lower the power of the mobile phone, the faster the charging speed. When the charging reaches more than 80%, the battery power is close to full power. In order to ensure the safety of use and prolong the battery life, when the battery is nearly full, the charging current output by the charger will gradually decrease, and the charging speed will slow down until it is fully charged.
2. During the whole charging process, the output current and voltage of the charger are not fixed, but will be dynamically adjusted according to the state of the mobile phone. Because of this, sometimes you may mistakenly think that the charging of the mobile phone is slow or that there is a problem with the charger. This is normal, please use it with confidence.

If the battery level is abnormal, please restart the phone or back up important data and restore the phone to factory settings.
If the problem still exists, please replace the battery in time or contact the service outlet for overhaul

There are many reasons why the phone does not increase or decrease when the phone is charged, but the battery power does not increase or decrease. Please troubleshoot according to the following solutions:
1. Please avoid using the mobile phone while charging. Please clean the background application of the device or turn off the device before charging. Because the mobile phone is running the program when charging, or the system has a problem of high power consumption, the current input by the charger may not be enough to offset the power consumed by the mobile phone itself, and sometimes the power does not increase during charging, but sometimes the charging decreases.
2. Avoid using the computer or the USB port of the car to charge the mobile phone. It is recommended that you use the standard charger for charging. Because the output current of the computer or car USB interface is very small and unstable, if the output current is too small, it cannot offset the power consumed by the mobile phone and the power will not increase.
If the charging is normal, the charger may be faulty. It is recommended that you purchase the standard charger for charging after the sale.
3. If the charging is still abnormal, the mobile phone may be faulty. Please back up important data in advance, and take the purchase invoice to the after-sales outlet for testing and processing.

Please check if you are using the original charger. Non-original small load chargers or computer USB ports have charging current limitations. When the battery of the mobile phone is over-discharged, the current is too small to support the phone to be turned on, causing the phone to restart repeatedly. It is recommended to use the original charger for charging.
If the battery is completely exhausted, please charge it for about ten minutes before trying to turn it on.
After the above operations, if the problem still exists, please back up the data in advance and bring the purchase invoice to the after-sales service point for maintenance.

The advantage of the OTG reverse charging function can instantly turn a smartphone into a mobile power supply and directly charge other electronic devices. The maximum output voltage is 5V, and the maximum output current is 500mA.

There is a response to charging, but the battery power does not increase or decrease. In most cases, this phenomenon occurs because the mobile phone is running a program during charging, or the mobile phone system has a problem of high power consumption, resulting in insufficient current input from the charger to offset the consumption of the mobile phone itself. Therefore, charging occurs but the power does not increase and sometimes the charging decreases. In addition, this phenomenon may also occur when the mobile phone is connected to the computer for charging or the charger is faulty, because the output current of the USB interface of the computer is very small and unstable.
1. Please avoid using the mobile phone while charging, and observe whether the mobile phone is charging normally when the mobile phone is not in use.
2. It is recommended to use the standard charger to charge the mobile phone, and avoid using the computer USB interface or devices with low output current to charge the mobile phone.
3. If the standard charger is used to charge the phone while the phone is turned on, the power will not increase. It is recommended to turn off the phone and charge it first. If the phone is turned off and charged normally, it may be caused by the rapid power consumption caused by the software. It is recommended to upgrade the system to the latest version, uninstall high-power-consuming applications on the phone, clean the background applications of the phone before charging, or restore the phone. Factory solved.
4. If the charger is turned off and the charging is still abnormal, the charger may be faulty. It is recommended to replace the charger.
