Why is the OPPO phone fast charging not fast charging anymore?

If the Oppo phone fails to charge quickly, the following situations may exist:

2. If the power adapter is overheated, unplug it for at least one minute and then connect the phone to charge.

3. The mobile phone battery is overheated and cannot be fast charged.

How to force boot up an OPPO phone

Generally speaking, there is no forced startup for OPPO phones. You can solve the problem by forced restarting. The specific method is:

1. Press and hold the power button for 5 seconds.

2. Press and hold the power button and volume button for about 8-10 seconds. After the phone is turned off, long press the power button again.

3. If the OPPO phone you are using is an old model before the R9S series, you only need to press and hold the power button for about 5 seconds. If the phone is normal, it can be turned on, but if the phone has a fault, it cannot be turned on. If it is frozen, just press and hold the power button for 10 seconds, then press and hold the power button after the phone is turned off.

4. If you are using an OPPO phone after the R9S series, you need to turn off the phone and then turn it on. Press and hold the power button and the volume up button for 8-10 seconds to make sure the phone is turned off, then press and hold the power button until it turns on to complete the restart of the phone.

What to do if your OPPO phone has a black screen and cannot be turned on

If your OPPO phone has a black screen and cannot be turned on, you can try:

1. First of all, we need to consider whether our OPPO phone is out of power. If there is no power in our phone, it will enter self-protection mode and cannot be turned on.

2. After connecting to the power source, you can try to press the power button of the phone to see if there is a charging sign. If there is a charging sign, it means that the phone itself is not broken.

3. If there is no response after long pressing the power button of the OPPO phone, we can use a mobile phone power bank to activate the phone battery. After charging it for more than ten minutes, try to turn it on. If there is a display, it means there is no problem.

4. If the phone still cannot be turned on after charging it with a power bank, there may be a problem with the phone’s internal software. At this time, we can only send it to a mobile phone repair shop for repair.
