If you hear a slight humming or buzzing sound while your phone is charging, please rest assured that this is usually a normal part of how electronic components work. It does not affect the safety or lifespan of your device.
To help address your concerns, please refer to the following guide based on the volume of the sound:
I. Faint sound, only audible when very close to the charger
When a charger or power bank is working, the internal electronic components are converting voltage and processing current. This process can sometimes create a very faint humming sound. This is a common physical phenomenon in electronic products. All realme products undergo strict safety certifications and multiple layers of protection, so you can continue to use them with confidence.
II. Noticeable sound, audible from a normal distance (over 1 meter away)
1. Check the outlet and accessories
Please try using a different wall outlet, charger, or cable to see if the sound persists.
If the sound disappears when using a different outlet, the original outlet may have a loose connection or be aging.
If the sound disappears when you switch to a different charging kit, the original charger or cable may be faulty.
2. Visit a Service Center for an inspection
If the sound is loud enough to interfere with your daily life, or if the issue continues after you have tried different accessories, we are here to help. For the best experience, please back up your important data and bring your phone and its charging equipment to a realme Customer Service Center. Our team will provide you with a professional inspection.
