Yes, it’s completely safe to charge overnight the device. realme phone comes with built-in hardware protection to prevent the device from overcharging & cut off the current when the phone gets fully charged.
Long time charge? Full night charge? What’s the safe charging method?
It’s not recommended to charge your device for a long time because it may reduce the battery life.
realme devices are equipped with circuits that would prevent charging automatically when the charging turns 100%.
1. If for any reason there is a risk of overcharging the battery, either from errors in determining the cut-off point, which will normally be accompanied by a rise in temperature, so it’s advised to cut off charging in time when the charging turns 100% and use optimized night charging feature for overnight charging.
2. At the same time, it is advised to do not fully discharge the phone as the full discharge cycle increases, the battery's capacity and lifespan will decrease. Please put the phone on charge as soon as the battery drops below 20%.
3. In addition, please use a realme charger and cable to charge your device to avoid the risk caused by incompatibility.
Hope this could help you to be clear about how to charge your device.
