5.1 Charging Your iPhone

- To stop charging your iPhone, press and hold the power button again for 2-3 seconds. The LED indicators will turn off, and your iPhone will cease charging from the case.
5.2 Checking Battery Level
Briefly press the power button on the back of the case. The LED indicators will light up to show the remaining battery capacity of the case:
- 4 LEDs: 75-100% charged
- 3 LEDs: 50-75% charged
- 2 LEDs: 25-50% charged
- 1 LED: 0-25% charged
6. Charging the Battery Case
- Connect the supplied Micro USB cable to the charging port at the bottom of the battery case.
- Connect the other end of the Micro USB cable to a USB wall adapter or a computer's USB port.
- The LED indicators on the back of the case will flash to indicate charging progress. All four LEDs will remain solid when the case is fully charged.
- When the iPhone is installed in the case and the case is connected to power, both the iPhone and the case will charge simultaneously. To charge only the case while the iPhone is installed, press and hold the power button on the case to stop charging the iPhone, then connect the case to power.
7. Maintenance
- Keep the case clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Avoid exposing the case to extreme temperatures, direct sunlight, or high humidity.
- Do not attempt to disassemble or modify the case, as this will void the warranty and may cause damage.
- Handle the case with care to prevent drops or impacts, which could damage both the case and your iPhone.
8. Troubleshooting
- iPhone not charging from case:
- Ensure the iPhone is properly seated and connected to the case's internal Lightning connector.
- Verify the battery case has sufficient charge by briefly pressing the power button.
- Activate charging by pressing and holding the power button for 2-3 seconds.
- Battery case not charging:
- Check if the Micro USB cable is securely connected to both the case and the power source.
- Try using a different Micro USB cable or power adapter to rule out cable/adapter issues.
- Ensure the power outlet is functional.
- Accidental charging activation:
- The power button is designed to be recessed to minimize accidental presses. If it activates unintentionally (e.g., in a pocket), ensure the phone is oriented such that the button is not subjected to constant pressure.
- "Accessory not supported" message:
- Although the case is MFi certified, this message can sometimes appear. Try removing and reinserting the iPhone into the case.
- Ensure the Lightning connector on your iPhone and the case's internal connector are clean and free of debris.
- If the issue persists, contact Anker customer support.
