The iPhone 15 has garnered attention for its remarkable capabilities, but some users have experienced battery issues and overheating concerns, often attributed to certain third-party applications. While Apple acknowledges these problems and collaborates with developers on solutions, there are practical steps that users can take to enhance the device’s battery life and mitigate heating issues. In this article, we present a range of tips and strategies to optimize the iPhone 15’s battery performance, potentially extending its autonomy by nearly two days.
Addressing iPhone 15 Battery and Overheating Problems

Apple has acknowledged battery and overheating issues related to specific third-party applications and is actively working on resolutions. In the interim, we offer straightforward solutions to enhance battery performance and reduce overheating.
Analyzing Battery Usage
Access the iPhone’s settings and navigate to “Battery” to scrutinize battery usage details. For a more comprehensive overview, select “Last 24 Hours.” Identify applications responsible for excessive battery consumption. For instance, Instagram may account for a substantial portion of resources.

Activating Low Power Mode
Enable Low Power Mode to curb background application activities and conserve battery life. Low Power Mode suspends email updates, background app refresh, and automatic downloads. Access this mode via “Settings” > “Battery” or use Siri for quick activation. For convenience, add Low Power Mode to the Control Center by customizing controls.
Manage Screen Auto-Lock
Optimize battery life by adjusting the auto-lock feature. Set the device to automatically lock after 30 seconds of inactivity to prevent unnecessary energy consumption. Prolonged auto-lock intervals may strain battery life.

Utilizing Automatic Brightness
In “Settings” > “Display & Brightness,” select automatic brightness to adapt screen illumination based on ambient conditions. This feature ensures optimal visibility without overexerting battery resources.
Disable Always-On Screen (Applicable to Pro Models)
Disable the “Always-On Screen” feature available on Pro models to prevent battery drain and screen wear. This feature keeps the screen constantly active, a potential source of diminished battery life.
Conclusion
While Apple addresses iPhone 15 battery and overheating issues associated with specific third-party applications, users can implement practical strategies to improve battery life and mitigate heating concerns. By carefully monitoring battery usage, enabling Low Power Mode, optimizing screen auto-lock settings, and utilizing automatic brightness, users can extend the autonomy of their iPhone 15. These measures provide valuable solutions as Apple continues to work on long-term resolutions.
