Charging Smart in Extreme Cold: Understanding OPPO’s Extreme Cold Mode
What Is Extreme Cold Mode?
Extreme Cold Mode is an intelligent charging protection feature that allows supported OPPO devices to charge even in environments as cold as –20°C (without wind).
When this mode activates, your phone will display an “Extreme Cold Mode” prompt, informing you that the system is taking protective measures.
How Extreme Cold Mode Works
Lithium-ion batteries do not charge well in very cold temperatures. Charging them when they are too cold can cause:
Long-term battery degradation
Reduced charging efficiency
Potential battery malfunction
To prevent this, OPPO uses an automatic battery preheating mechanism:
The phone detects extremely low ambient temperatures.
Extreme Cold Mode activates automatically.
The system gently warms the battery before charging.
Once the battery reaches a safe temperature range, normal charging gradually resumes.
This ensures your phone charges safely—not just quickly.
Why Charging May Be Slower in Extreme Cold Mode
You may notice slower charging than usual. This is normal, because:
The phone is warming up the battery first
Fast charging is restricted during unsafe temperature conditions
Safety always comes before speed, especially in freezing environments.
No Manual Settings Required
You don’t need to turn anything on or off.
Extreme Cold Mode:
It is always enabled in the system
Activates automatically when required
Turns off when the phone returns to a warmer environment
Simple, seamless, and fully automated.

⚠️ If Extreme Cold Mode Appears in Normal Room Temperature

In such cases:
➡️ Visit an authorized OPPO Service Center
➡️ A motherboard diagnosis or replacement may be required
