How does the OPPO R9M charge fast? My charge is slow, and when I use it, the power goes down very qu

This requires the original charger to charge the phone in order to enjoy the charging experience of flash charging.

The power consumption of the phone is related to the specific usage.

1. Adjust the brightness of the mobile phone screen reasonably, set the appropriate screen brightness, and it is not recommended to be too bright;

2. Turn off some uncommonly used WIFI, NFC, Bluetooth, GPS and other switches to save mobile phone power;

3. Turn on the pure background of the mobile phone to save power (some models do not have the pure background function);

4. Turn off the account and synchronization function of the mobile phone;

5. Turn on the power-saving mode;

6. Enter Settings - Gesture Somatosensory, enter and turn off some unused gesture somatosensory functions;

7. When not operating the phone, it is recommended to clean up the open apps on the phone with one click to save power.

In the shutdown state, using the original charger, you can enter the state of fast charging, that is, flash charging.

Conditions for entering flash charging:

1.The mobile phone must use the original special lithium battery, which is used with a special flash charger or flash charge mobile power bank;

2.Battery power 1%--85% (due to various factors, there may be fluctuations);

3.The phone's battery temperature is in the range of 15 43, and when the temperature range is exceeded, the phone automatically switches back to the standard charging mode.

When the weather gets colder, for example, below 15 degrees Celsius, it will slow down or stop flashing.

If your phone does not support flash charging, it is normal for your phone to charge for 2-3 hours. If the charging time of the mobile phone exceeds this range, we recommend that you check the mobile phone in the following ways:

1. Please make sure to use the original OPPO charging head and charging cable, non-original charging head and data cable may cause unstable voltage and current.

2. You can try to replace the charging head and data cable to rule out the abnormal charging head or data cable.

3. Using the mobile phone while charging will cause the charging current to decrease and the charging speed to become slower, so it is recommended to use the mobile phone after the mobile phone is fully charged.

4. Clean up the background running program of the phone and try to restart the phone.

5. The charging speed of the mobile phone is related to the ambient temperature, the temperature is too high or too low will make the charging speed of the hand lead imitation celebration machine slower, please use and charge at the ambient temperature of 5 degrees -35 degrees.

If the charging speed of the mobile phone is still slow after trying the above methods, it is recommended that you bring the purchase invoice, warranty card and mobile phone to the OPPO customer service center for testing, and a professional engineer will handle it for you.

This is available for all OPPO models.

1. If possible, it is recommended to replace a set of OPPO (Super) flash charger to see if the adapter or data cable is broken.

2. It is recommended that you stop using high-power software when charging, especially games, cameras, etc., and then check the charging situation, if the phone is seriously heated, it is recommended that you restart the phone and wait for the temperature to drop before charging.

3. The ambient temperature is too high or too low, which will affect the charging speed of the lithium battery, it is recommended that you charge the mobile phone after cleaning the background program with one click in a suitable environment of 15 35.

4. It is recommended that after restarting the phone, reopen and plug the data cable to recharge.

If the above methods are of limited help to you, please bring the purchase invoice, warranty card, hand defense and charger to the nearest lead OPPO customer service center and a professional engineer will test and process it for you.

This applies to all OPPO models.

Reasons: 1. Low temperature will affect the activity of the battery, resulting in slow charging. If the ambient temperature is normal (15 to 35 °C), charging is slow;

2. Use a non-original charger for charging;

3. Power socket failure;

4. Mobile phone hardware problems.

Here's how we recommend you try:

1. Use the original charger to charge;

2. When turning on and charging, it is recommended to close the background program that is not in use;

3. Replace the power socket and try to charge;

4. After backing up important data (contacts, multiple files, etc.), then restore factory settings.
