Part 2. 5 Common Causes of iPhone Battery Problems
To know what battery issue reasons lead to the usage of Wondershare Dr.Fone and other ways, review the listed points:
- A battered or aged battery is worthless and cannot store a charge.
- Bad chargers and cables may harm the battery and charge it slowly.
- The battery runs down in a short time when many apps or heavy tasks run continuously.
- Inaccurate battery readings or quick battery drains can be the result of software bugs or an old iOS.
- High or low temperature impacts battery chemistry and degrades performance or drains fast.
Part 3. Battery Draining or Not Charging? Fix It Step-by-Step
Follow the listed ways and learn how iOS system repair software and basic fixes can resolve the battery issue:
Fix 1: Restart the iPhone
This solution stops stuck apps, resets power services, and refreshes the connection between iOS and the battery. It can also reduce fast drain, restore normal charging, and make the battery percentage more accurate. So, as it is quick, safe, and does not delete data, here is how you can do it:
Step 1. Press the “Power” and “Volume Up” buttons until you get the “Slide to Power Off” slider.

Step 2. Slide it, wait for a few seconds, and press the “Power” button to restart.

Fix 2: Check Charging Cable, Adapter, and Power Source
Before using the iOS system repair tool, check the charging cable, adapter, and power source to fix battery or charging issues. Besides, it is suggested to use certified, high-quality accessories to restore normal charging and protect the iPhone from damage.
Fix 3: Clean the Charging Port
Dust and lint can block the connector and cause weak or intermittent power. Hence, remove the debris from the phone to allow it to charge normally and consistently.
Fix 4: Close Background Apps and Reduce Screen Brightness
While trying other iOS system repair solutions, try to lower the screen brightness or close the background apps. This can help because the bright screen uses a lot of power. In addition, turning off the background apps via the mentioned steps can let more power go to the battery:
Instructions: From the middle of the screen, “Swipe Up,” and in the App Switcher, close the battery-drawing app. Afterward, reduce the brightness of your iPhone from the Control Center.

Fix 5: Turn On Optimized Battery Charging
This feature slows battery aging by keeping the charge around 80% until you need full power. Hence, it reduces chemical stress, helping the battery hold more capacity and drain more slowly over time. To enable that option via settings, adhere to the basic steps given below:
Instructions: In settings, choose “Battery > Battery Health & Charging > Optimized Battery Charging” option.

Fix 6: Update iOS to the Latest Version
Updating iOS can still fix battery drain or charging issues. New iOS versions improve power management, resolve system bugs, and optimize background tasks. Once updated using the illustrated steps, this can reduce excessive battery drain, overheating, and app-related power problems:
Step 1. Choose the “Software Update” option as you head to the “General” settings.

Step 2. Press the “Update Now” button to install the latest iOS version.
