**Introduction** Samsung’s One UI 7 and Android 15 update brought many new features and security improvements. However, many users face various issues such as fast battery drain, phone freezing, app crashes, heating problems, and delayed notifications after upgrading.
In this article, we will discuss effective steps you can take to resolve these post-upgrade problems and maintain your phone’s battery life and performance like before.
*1. Wipe Cache Partition**
Old system cache can cause issues. Boot into recovery mode and perform **Wipe cache partition** to clear temporary files.
*2. Enable Battery Optimization and Background Restrictions**
* Go to **Settings > Battery and device care > Battery > Background usage limits** * Enable “Put unused apps to sleep” and add unnecessary apps to “Sleeping/Deep Sleeping apps” * Check battery optimization for individual apps: **Settings > Apps > \[Select App] > Battery > Optimize usage**
*3. Keep Your Apps Updated**
After a system update, old apps may not be fully compatible with the new firmware and can cause problems. Always update your apps via the Play Store or Galaxy Store.
*4. Check in Safe Mode**
Boot your phone into safe mode to determine if third-party apps are causing issues. Safe mode disables all third-party apps temporarily.
*5. Optimize Screen Settings**
* Set **Motion smoothness** to “Standard (60Hz)” instead of “Adaptive” or “High” * Reduce **Screen timeout** to 15–30 seconds * Enable **Dark Mode** (especially effective on OLED screens) * Turn off **Always On Display**
*6. Manage Location and Sensor Permissions**
* Grant **Location permissions** only when necessary * Turn off **Wi-Fi scanning** and **Bluetooth scanning** * Disable NFC and Nearby Share when not in use
*7. Turn Off Nearby Device Scanning**
This feature continuously searches for nearby Bluetooth or Wi-Fi devices in the background, causing excessive battery drain.
* Go to **Settings > Connections > More connection settings > Nearby device scanning** and turn it **OFF**
*8. Disable Unnecessary Features to Prevent Hidden Battery Drain**
A. **Continue Apps on Other Devices**
* Go to **Settings > Advanced features > Continue apps on other devices** and turn it **OFF**
B. **SmartThings and SmartView (if not used)**
* Disable auto-connect or auto-scan options * Uninstall or disable the apps if unnecessary
*9. Send Software Feedback**
Report any persistent issues through the **Samsung Members app** under **Get help > Error reports** to help Samsung improve updates.
*10. Factory Reset (Last Resort)**
If all else fails, perform a **Factory Data Reset** to restore your phone to clean settings and set it up again.
*Conclusion**
While new Android and One UI updates bring useful features, certain “always-on” connectivity features like **Continue apps on other devices**, **Nearby device scanning**, and **SmartThings** silently increase battery consumption. Managing these settings consciously will help you enjoy longer battery life and smooth smartphone performance.
Yes, many users have reported experiencing similar problems. This can be due to the phone re-optimizing itself after the update or apps needing to be optimized for the new firmware. Add apps to the "deep sleep" list to prevent them from running in the background and draining battery.
Clear app cache to remove temporary data that can impact performance and battery usage. Resetting battery statistics can sometimes help.
Adjust background usage limits in Settings > Battery and device care > Battery > Background usage limits.
Choose options like "Put unused apps to sleep" or "Sleeping apps" to restrict background activity.
