Let's jump straight into the most common fix. Plug your OnePlus 13 into its original 100W charger and cable, and let it sit for at least 30 minutes. A completely drained battery can sometimes take a few minutes of charging before it will even show the charging indicator. If you see the battery icon or a charging animation, you're on the right track.
Perform a Force Restart
If the screen is black and unresponsive, a force restart is your next step. This is different from a normal power-off and can clear temporary software glitches. Press and hold the Volume Down button and the Power button together for about 10 seconds.
You should feel a vibration, and the OnePlus logo should appear. If it doesn't, try holding the buttons for a full 15-20 seconds just to be sure. I've found this resolves a surprising number of "won't turn on" issues with recent OnePlus models.
Check Your Charging Setup
A faulty cable, worn-out wall adapter, or even a dirty USB-C port can prevent your phone from getting the power it needs. First, inspect the USB-C port on the bottom of your OnePlus 13. Use a flashlight and a wooden or plastic toothpick to gently clear out any packed-in lint or debris.
Next, try a different charging combination. If you have another USB-C cable and a reliable charger (even if it's slower), use that. Avoid charging from a computer's USB port for this test, as the power output is often too low to kick-start a deeply drained battery.
For wireless charging, place your phone on a compatible Qi2 or MagSafe charger. The OnePlus 13 supports up to 50W wireless charging, but any standard Qi charger will work for a basic power check. Remove any thick cases that might be interfering with the connection.
Boot Into Safe Mode
If your phone powers on but gets stuck on the OnePlus or OxygenOS logo, a recently installed app might be the culprit. Booting into Safe Mode temporarily disables all third-party apps. First, force restart the phone as described earlier.
The moment you see the OnePlus logo appear, release the Power button but keep holding the Volume Down button. Keep holding it until you see the lock screen. You should see "Safe Mode" in the bottom corner of the display.
If the phone boots successfully in Safe Mode, you know a downloaded app is causing the problem. You can then restart normally and try uninstalling apps you installed just before the issue started.
Try Recovery Mode for a Cache Wipe
Corrupted system cache files can also prevent a normal boot. You can clear these without deleting your personal data. To enter Recovery Mode, first power the phone off completely. Then, press and hold the Volume Up and Power buttons together.
When you feel the vibration, release the Power button but keep holding Volume Up until you see the recovery menu. Use the volume keys to navigate to "Wipe data and cache" and select it with the power button. Then, choose "Wipe cache" and confirm.
Once it's done, select "Reboot" and see if your OnePlus 13 starts normally. This process takes about 30 seconds and is a great step before considering more drastic measures.
Address Potential Overheating
The OnePlus 13 is powerful, and early reports note it can get warm during intensive use. If the phone overheats, it has safety mechanisms that can shut it down and may prevent it from turning back on until it cools.
If you were just gaming, using the camera, or fast charging, let the phone sit in a cool, shaded area for at least 15-20 minutes. Then, try the force restart again. Avoid leaving it in direct sunlight or on a blanket while charging, as this can exacerbate heat issues.
Connect to a PC or Laptop
Sometimes, connecting to a computer can provide just enough of a "handshake" to wake the phone up. Use a known-good USB-C cable to connect your OnePlus 13 to a Windows PC or Mac. Listen for the connection sound on the computer or check to see if a new drive appears.
Even if nothing shows up on the computer, leave it connected for a few minutes, then try the force restart sequence while it's still plugged into the PC. The steady, low-power feed from a computer's USB port can sometimes stabilize the device's power management system.
Perform a Factory Reset (Last Resort)
If all else fails, a factory reset from Recovery Mode is the final software step. This will erase all data on your phone, so it's only for situations where you cannot get the phone to boot at all and you have no other option.
Enter Recovery Mode using the Volume Up and Power button method. Navigate to "Wipe data and cache" and select it. Then, choose "Erase everything" or "Factory reset." Confirm your selection. After the process completes, select "Reboot."
Your phone will take longer than usual to start up as it prepares the system for the first time. If the hardware is functional, this should get you back to the initial setup screen.
