Google is continually working to improve the functionality and user experience of its Pixel smartphones. One of the latest features discovered in the reverse-compiled code of Google’s Device Health Services application version 1.27 is “Adaptive Thermal.” This new feature, designed to prevent overheating, aims to safeguard the phone’s battery and overall performance by triggering alarms and notifications when temperatures exceed safe limits.
What is Adaptive Thermal?
Adaptive Thermal, as uncovered by technology media Android Authority, is a feature that activates when the battery temperature of a Pixel phone rises to potentially harmful levels. The primary goal of this system is to alert users before their device reaches critical temperature thresholds, thus preventing damage and maintaining optimal performance.
How Adaptive Thermal Works
Pre-Emergency Alarm
When the battery temperature exceeds 49 degrees Celsius, Adaptive Thermal triggers a “pre-emergency” alarm. This alert notifies users that their phone is overheating and provides immediate steps to cool it down. The notification suggests avoiding direct sunlight and closing any power-consuming applications.
Cooling Instructions
The notification includes a “See Care Steps” button, which, when clicked, offers more detailed advice on cooling the device. These suggestions may include:
Gizchina News of the week
- Reducing Performance Speed: Temporarily slowing down the phone’s performance to decrease heat generation.
- Disabling 5G Network: Turning off the 5G network to lower power consumption and heat output.
- Avoiding Direct Sunlight: Keep the phone away from direct sunlight to prevent additional heat buildup.
- Improving Air Circulation: Placing the phone in an open, well-ventilated area to facilitate cooling.
- Closing Power-Intensive Applications**: Shutting down apps like video players, games, and cameras that significantly contribute to the phone’s heat generation.
Sampling and Emergency State
Adaptive Cooling regularly monitors the battery temperature, taking samples every five minutes. If the temperature does not decrease and reaches 52 degrees Celsius (about 126 degrees Fahrenheit), the system escalates to an “emergency” state. While the specific actions taken in this state are not explicitly detailed, it is expected that more aggressive cooling measures will be implemented.
Critical Shutdown Warning
Should the battery temperature continue to rise and hit a dangerous 55 degrees Celsius (about 131 degrees Fahrenheit), Adaptive Thermal will issue a final warning 30 seconds before automatically shutting down the phone. This preemptive shutdown is a protective measure designed to prevent further damage to the device.
Importance of Adaptive Cooling
Overheating is a common issue in smartphones, often leading to decreased performance, battery damage, and in severe cases, permanent hardware failure. By implementing Adaptive Thermal, Google aims to enhance the longevity and reliability of its Pixel phones. This feature not only protects the device but also ensures a smoother and safer user experience.
Conclusion
Google’s introduction of the Adaptive Thermal feature in its Pixel phones marks a significant step towards improving device safety and performance. By proactively managing battery temperature and providing users with actionable cooling steps, this system helps prevent overheating and potential damage. As smartphones continue to become more powerful and complex, such innovations are crucial in maintaining their efficiency and durability. With Adaptive Thermal, Pixel users can expect a more robust and resilient device, capable of handling the demands of modern smartphone use while minimizing the risks associated with overheating.
