Why My Refurbished iPhone 8 Even with 91 Battery Health is Draining Quickly: Troubleshooting Tips
Having a refurbished iPhone 8 with 91% battery health can still be frustrating if it drains quickly. Here are several reasons and steps to help you address the issue and save battery life.
Background App Activity
Background app activity can significantly drain your battery. To diagnose which apps are using the most power, go to Settings > Battery > Battery Usage. Identify the key culprits and disable background app refresh for them if they're not essential.
Software Issues
Software glitches or outdated firmware can cause battery drain. Ensure your iPhone is updated to the latest version of iOS. If you recently updated, the system may take some time to optimize its performance. Check for any recent updates in Settings > General > Software Update.
Battery Age and Usage Patterns
Even with 91% battery health, older batteries may have reduced capacity and efficiency. This can lead to quicker drain. Heavy usage, especially with demanding tasks like gaming or streaming, can also lead to faster battery depletion. To manage battery usage, use Settings > Battery > Battery Usage.
Temperature Effects
Extreme temperatures, whether too hot or too cold, can negatively impact battery performance. Ensure your device is used within the recommended temperature ranges. To find these ranges, look for official manufacturer guidelines or check Settings > Battery > Battery Health > Battery Temperature.
Location Services
Constantly active location services can drain your battery. In Settings > Privacy > Security Privacy > Location Services, review the permissions of apps needing location data and consider disabling them if necessary or adjusting their settings.
Notifications and Widgets
Frequent notifications or active widgets can keep your screen on and drain the battery. Consider setting a notification threshold or disabling push notifications for less important apps. Reduce the frequency of widget updates by going to Settings > Notification Center > Summary > Notification Summary.
Screen Brightness
High screen brightness can consume a significant amount of battery. Try reducing it or enabling auto-brightness mode, which adjusts the display brightness based on ambient light. To adjust screen brightness, go to Settings > Display Brightness.
Network Issues
Poor cellular or Wi-Fi signals can cause your phone to work harder to maintain a connection, leading to faster battery drain. Optimize your network settings by ensuring you're using the best available network. Adjust network settings in Settings > Network Internet > Cellular.
If you've adjusted all of these settings and the issue persists, it may be time to consider getting the battery replaced. Even with 91% health, the battery could still be underperforming due to age or other factors. Schedule an appointment with an authorized repair center to check the battery and, if necessary, replace it.
