Oppo Reno series has become extremely popular for its stylish design, greater camera features, and dependable performance. But, like any other smartphone, once in a while, a charging problem may appear. If your Oppo Reno is charging slowly, not charging at all, or just randomly disconnecting, then don't sweat-it! This detailed set of instructions will aid you in identifying and fixing the problem.
Common Charging Issues in the Oppo Reno Series
Before one could embark on solutions; it should be to understand what common faults users encounter while charging by avoiding later mistakes.
Phone not charging even when plugged in
Slow charging despite using the original charger
- Charging percentage stuck
- Battery draining fast while charging
- Phone overheating during charge
- Cable or adapter gets hot
- Charging pauses intermittently
- "Moisture detected" or debris warning
An answer to one or all these could be the software, the hardware, or a combination of both.
Inspect Your Charging Cable and Adapter
Start with elementary checks.
- Use the original charging adapter and USB-C cable supplied by Oppo.
- If you have an alternate charger or cable in your possession, do try it.
- Check on bent connectors, fraying occurring in cables, or loose-set pins. Clean the USB-C port gently with a soft brush or toothpick to rid it of dust or lint.
Tip: If the cable sits loosely in the port or just comes off on its own easily, there is a good chance that either the port is damaged or some blocking is preventing an easy connection.
Clean the Charging Port
Dirt, lint, or moisture can cause poor connectivity. Here’s how to clean it:
- Turn off the phone.
- Use a flashlight to check the port.
- The debris can effortlessly be removed through brushing it gently with a fine bristle toothbrush, pushing it gently with a wooden toothpick, or blowing it away with an antistatic air blower.
- Never use metal objects or water.
Note: After getting wet, let the port dry for at least an hour before charging again.
Restart or Force Reboot Your Device
A simple restart is all that is needed for such software bugs to be fixed, even if for just a short time:
- Hold the Power button down.
- Tap Restart.
When the phone does not respond:
- Press and hold the Power + Volume Up buttons simultaneously for 10 seconds for a soft reset.
Check for Software Updates
An old firmware might be hindering the proper charging of your Oppo Reno:
- Go to Settings > Software Update.
- Check for updates and, if available, download and install them.
Oppo often releases bug fixes and system enhancements that might be able to fix your charging issues.
Enable Airplane Mode or Switch Off While Charging
Applications and background processes may keep the charging process slow:
- Turn on Airplane Mode so battery usage diminishes during charging.
- Better still, turn off the phone while charging.
- Now the phone may be charged without a power consumption interruption.
- Use Safe Mode to Check for App Conflicts
In some instances, third-party apps may impede the process of charging the phone; hence, ascertain this by going for Safe Mode:
- Press and hold the Power button.
- Tap and hold the Power Off icon until the option to "Reboot to Safe Mode" appears.
- Tap OK.
Now charge the device. If it works fine, uninstall recently installed apps.
Calibrate the Battery
If your Oppo Reno gives an incorrect battery percentage or shuts down early, a battery calibration might assist you:
- Drain battery until it reaches 0% and the device powers off;
- Now, without any interruptions, charge it fully, or 100%.
- Use your phone until it again reaches 0%.
- Charge to 100% again—this should reset the battery statistics.
Check for Overheating
Overheating can slow or stop charging altogether. Avoid the following:
- Charging while gaming or using heavy apps
- Charging in hot environments
- Using third-party fast chargers
To stop overheating, think about taking off the phone casing while charging, or you can cool your device before plugging it in in turn.
Use the Oppo Device Manager or Battery Health Tools
Oppo’s ColorOS has built-in tools to check battery status:
- Go to Settings > Battery > Battery Usage to identify unusual power drain.
- Use Phone Manager app to clean up background apps and optimize performance.
In case, reset all the settings by going to Settings > Additional Settings > Backup and Reset.
Visit a Certified Oppo Service Center
If you have tried all of the solutions above and the Oppo Reno phone still isn't charging properly, you might have a hardware problem associated with:
- Defective charging port
- Damaged battery
- Faulty motherboard
Visit a nearby Oppo service center for a full hardware inspection. Always insist on genuine parts if any replacements are suggested.
Extra Tips to Extend Battery and Charging Health
- Avoid overnight charging regularly.
- Don’t let your battery go below 10% too often.
- Use Oppo’s SuperVOOC charger only if your Reno model supports it.
- Always unplug after full charge to reduce battery stress.
- Avoid charging from laptops or power banks frequently.
