Try to minimise the apps and functions you are using at any one time.
In most cases it is normal for your phone to feel warm, for example, when you are using multiple high-performing apps, listening to music for an extended time, or when your phone is charging.
Your phone meets Nokia’s high standards for device safety. Nokia also meets the international standard for safety (IEC 60950-1) and country-specific requirements.
To avoid getting too warm and to protect itself, your phone may automatically slow down, close apps and, if necessary, switch itself off.
