You set your OnePlus Open down on a wireless charging pad, waited for the battery icon to start climbing, and nothing happened. The pad might even glow or blink as if it has found a phone, yet your OnePlus Open never registers a single percent of power. Before you swap pads, buy a "certified" charger, or assume the foldable is faulty, there is one fact that changes the entire picture and points you to the fixes that actually work.
Why Your OnePlus Open Cannot Charge On A Wireless Pad
The OnePlus Open does not support wireless charging of any kind. According to the manufacturer's official specifications, the phone ships with a 4,805 mAh dual-cell battery and 67W SUPERVOOC charging delivered over a USB Type-C cable, and that is the only charging method listed. There is no Qi, Qi2, or MagSafe charging coil mentioned anywhere in the official spec sheet or the user manual.
That means a wireless charging pad physically cannot power this phone. The hardware needed to receive wireless energy was never built into the device, so no hidden setting, toggle, app, or firmware update can switch it on. Wireless charging is a capability the manufacturer has said arrives on the later OnePlus Open 2, not the original OnePlus Open.
So the genuine fix is to stop troubleshooting a feature that does not exist and instead confirm that the phone's actual charging method, wired USB-C, is working properly. The steps below walk through exactly that, starting with the simplest and safest checks and ending with the official repair path.
Begin With The Official Charger, Cable, And A Wall Socket
The most common reason an OnePlus Open "will not charge" is a weak or faulty charging source rather than the phone itself. The user manual is explicit on this point: "To ensure your safety and avoid damaging the device, only use the official charger and USB cable. OnePlus device supports the USB Type-C cable." A worn third-party cable, a damaged adapter, or a low-power USB port can stop charging or slow it to a crawl.
Set up the connection the way the manual describes, in this order:
- 1.Connect the USB cable to the adapter.
- 2.Plug the USB cable into the phone's USB-C port.
- 3.Plug the adapter into a power socket.
Use a proper wall socket rather than a computer port or a multi-device hub for this test, since those often cannot deliver the power the OnePlus Open expects.
Reseat The Cable And Check The USB-C Connection
A connection that looks plugged in is not always seated all the way. Even a slightly loose USB-C cable, at either the phone end or the adapter end, will interrupt charging or cause it to drop in and out.
Unplug both ends of the cable, then firmly re-insert the cable into the phone's USB-C port and back into the adapter so each end clicks into place. If you can wiggle the cable in the port and watch the charging indicator flicker on and off, you have likely found the problem, and the next step is to try a different official cable and adapter to confirm whether the fault is in the accessory or the port.
Keep The Phone Inside Its Charging Temperature Range
Heat and cold both affect how an OnePlus Open accepts a charge. The manual recommends operating the phone in a comfortable range, stating it "is recommended to use between 15°C and 35°C degrees." If the device has been sitting in a hot car, in direct sun, or somewhere very cold, charging can slow down or pause entirely as a protective measure.
Move the phone somewhere at normal room temperature, let it settle for a few minutes, then try charging again. It also helps to avoid trapping heat while the phone charges, so removing a thick case during a charge can let the foldable shed heat faster.
Rule Out Optimised Charging Holding The Battery Back
If your OnePlus Open seems to stall before 100 percent or appears to stop charging overnight, that may be intentional battery protection rather than a fault. The phone has a feature designed to slow battery aging by learning your routine and delaying the final stretch of charging until you are about to use it.
To review or change it, go to Settings > Battery to view battery details and set battery preferences. There you will find Optimised charging with options for Off, At night, and All day. As the manual explains, this feature "learns your charging habits and waits to finish charging past 80% until just before you start using your device." If you want the phone to charge straight through to 100 percent every time, set Optimised charging to Off.
Restart The Phone To Clear A Charging Glitch
A simple reboot clears temporary software hiccups that can block the phone from recognising a charger. Follow the official restart sequence from the manual: "When powered on, press power button and volume up button simultaneously, and then tap 'Restart' to reboot the device." Once the phone is back on, plug it in again and watch for the charging indicator.
Force A Reboot When The Screen Is Frozen
If the OnePlus Open is unresponsive, stuck on a black screen, or frozen while plugged in, a forced restart can bring it back. The correct sequence for this phone uses the power button together with volume up, not the power button on its own. The manual states: "When powered on, long press the power button and volume up button for 10 seconds, the phone will shut down, and then press the power button to turn on the device again."
The same shortcut is described as a quick way to cut power: "Long press the power button and volume up for 10 seconds to force a power off." Holding only the power button does not perform this reset, so be sure to press and hold both buttons.
Update OxygenOS To Patch Charging Bugs
Charging problems are sometimes caused by software issues that the manufacturer resolves in a later release of OxygenOS. Installing the newest version available for your phone can quietly fix the behaviour.
Check for an update by going to Settings > About device > Software update. As the manual describes it, the system then starts to check for updates, and you "follow the instructions to download and update." Keep the phone connected to Wi-Fi and reasonably charged before you begin, then let the update finish without interruption.
Back Up And Factory Reset As A Last Software Step
If wired charging still fails after every step above, a factory reset removes any deeper software cause. This step erases your phone, so treat it as a last resort and back up first. The manual warns: "Restoring factory settings will wipe all app data, contacts, text messages, and so on. Backup important data before a factory reset."
Once your data is safely backed up, follow the official procedure:
- 1.Go to Settings > Additional settings > Back up and reset > Reset phone.
- 2.Tap Reset phone.
- 3.Enter your passcode if a passcode is enabled.
- 4.Wait until the factory reset is complete.
After the phone restarts as new, test charging again before you restore your backup, so you can tell whether the problem was software-based.
When To Let OnePlus Support Take Over
If the OnePlus Open still refuses to charge after a clean reset, the cause is most likely hardware, such as a damaged USB-C port, a worn battery, or a failing charger. Continuing to experiment at home will not repair a physical fault, and forcing a stubborn cable into a damaged port can make things worse.
At this stage, use the manufacturer's official support site to start a diagnosis or arrange a repair through an authorised service center. A technician can test the port and battery directly and replace any faulty component safely.
Frequently Asked Questions
Does the OnePlus Open support wireless charging at all?
No. The official specifications list a 4,805 mAh battery and 67W SUPERVOOC wired charging over USB Type-C only, with no Qi, Qi2, or MagSafe coil. The phone cannot draw power from a wireless pad under any circumstances, and no setting can add the feature.
Why does my OnePlus Open stop charging at around 80 percent?
This is usually Optimised charging working as designed, not a fault. The feature waits to finish charging past 80 percent until just before you typically use the phone. You can switch it off in Settings > Battery if you prefer the phone to reach 100 percent right away.
What is the correct way to force restart a frozen OnePlus Open?
Long press the power button and the volume up button together for 10 seconds. The phone will shut down, and you then press the power button to turn it back on. Holding the power button alone does not trigger this reset.
My phone charges very slowly. What should I check first?
Use the official charger and USB-C cable plugged into a wall socket, make sure both ends of the cable are firmly seated, and keep the phone within the recommended 15°C to 35°C range. A weak USB port, a third-party cable, or a hot phone are the most common reasons charging slows down.
When should I contact OnePlus instead of trying more fixes?
If the phone still will not charge after restarting, updating OxygenOS, and performing a backed-up factory reset, the USB-C port, battery, or charger may be faulty. At that point, contact OnePlus official support or visit an authorised service center for a hardware diagnosis.
