Why Does My Charger Get Warm?
During power conversion, it is natural for some energy to dissipate as heat. This is a normal physical phenomenon, particularly with fast charging, where higher power output may result in slightly higher temperatures.】
Your Safety is Our Priority
Rest assured, all realme chargers feature built-in over-temperature protection. If the temperature exceeds preset safety limits, the charger will automatically adjust the power output or pause charging until it cools down. You can use your realme charger with complete confidence.
Tips to Keep Your Charger Cool:
I. Accessory Selection & Inspection
1. Always Use Original Accessories
Non-original adapters and cables may have unstable voltage and current output, and might not be compatible with your phone's fast charging protocol. This can lead to inefficient charging and abnormal heat. We strongly recommend always using the original, official charger and cable that came with your phone to ensure safe and efficient charging.
2. Check Port Cleanliness & Condition
Dust, debris, or liquids inside the charging ports can increase contact resistance, leading to noticeable heat. Please regularly check and gently clean the charger plug and your phone's charging port. If you notice any damage to the cable or severe oxidation on the plug, we advise replacing them promptly to prevent high temperatures caused by poor contact.
II. Charging Environment & Habits
1. Ensure a Well-Ventilated Charging Environment
Your charger needs good ventilation to dissipate heat properly. Avoid charging in hot environments (like direct sunlight or inside a car in summer) and do not place the charger on surfaces that trap heat, such as sofas or blankets. We recommend placing it on a well-ventilated desk or floor while charging.
2. Avoid Heavy Use While Charging
While your phone supports charging during use, playing demanding games or watching videos while charging puts both your phone and charger under high load simultaneously, leading to rapid heat buildup. We suggest charging your phone while it's idle or in standby mode. This helps lower the device temperature and speeds up charging.
