In most cases, it’s due to the OPPO OnePlus 9 Smartphone Battery entering deep sleep mode or an accessory issue; in a few cases, it’s a hardware malfunction.I. OnePlus 9 Phone Battery Won’t Charge After Being Completely Drained (Deep Battery Sleep)
If the phone automatically shuts down after being completely drained, and there’s no response when plugged in the charger, the OnePlus 9 phone battery may have entered deep sleep mode, not actually damaged. OnePlus’s official method: Use a regular charger and data cable to charge continuously for 20 minutes, without touching the power button during this time. Wait for the OPPO OnePlus 9 Smartphone Battery to activate and the screen to automatically light up. If this doesn’t work, connect the phone to a computer’s USB port and repeat the above steps.
II. OnePlus 9 Phone Battery Charging Intermittently or Only Wireless Charging (Charging Board Fault)
If the USB-C port cannot charge at all, but wireless charging works normally, iFixit repair personnel believe this is most likely due to a damaged charging board. The OPPO OnePlus 9 Smartphone Battery charging port is soldered onto a small board, requiring replacement of the entire board, not just the connector. If the indicator light flashes briefly upon plugging in the charger and then goes out, or if charging requires a specific angle, it indicates that the connector pins may be worn or have poor soldering.III. OnePlus 9 Battery Level Display Skipping (Battery Aging)A sudden drop in battery level from 30% to 1% upon power-on is a typical sign of OnePlus 9 battery aging, requiring replacement. The original OPPO OnePlus 9 Smartphone Battery is model BLP821 (4500mAh); be sure to select the corresponding model when replacing.IV. Basic TroubleshootingFirst, test with a known working charger and data cable; clean the USB-C charging port with a small brush to remove dust; try a different wall outlet to rule out voltage issues.V.
