My Charging Module charges too slowly. What can I do?Updated 4 days ago

SP-Connect charging solutions including the SP-Connect Charging Module support wireless charging with up to 15 W. However, the actual charging speed achieved may vary depending on the smartphone, power source and environmental conditions. This is normal for wireless charging and does not necessarily indicate a defect.

Why charging speed can vary

• Smartphone compatibility & charging protocol: Not all smartphones support the same wireless charging profiles. Some devices charge more slowly via wireless charging or reduce charging power sooner than others.
• Temperature management: Heat generated by direct sunlight, navigation apps or other running applications can cause smartphones to automatically reduce charging power to prevent overheating.
• Power supply: If the power source cannot provide sufficient output, less energy will be available to the Charging Module.
• Simultaneous power consumption: Navigation, high screen brightness, mobile data or music streaming may consume so much power that the battery charges only slowly.
• Battery level and battery protection features: Many smartphones charge faster at lower battery levels and automatically reduce charging speed at higher charge levels, especially above approximately 80%.

Tips for improving charging performance

1. Use a suitable power source

• Use a power supply that supports Power Delivery (PD) or Quick Charge (QC 2.0 / 3.0 / 4.0) and provides sufficient output.
• A weak power source can significantly limit charging performance.

2. Ensure correct smartphone alignment

• Make sure the smartphone sits cleanly and flush on the Charging Module.
• Proper alignment is essential for optimal charging coil performance.

3. Reduce heat

• Protect the smartphone and Charging Module from direct sunlight whenever possible.
• Charge in a cooler environment if possible. Around 20°C (68°F) is ideal.
• If the smartphone becomes very warm, allow it to cool down briefly. Charging performance often improves afterwards.

4. Reduce power consumption while charging

• Enable adaptive brightness or reduce screen brightness.
• Close unnecessary background applications.
• Use offline maps whenever possible during navigation.
• Disable wireless connections that are not needed while riding.

5. Check charging performance at a low battery level

• Evaluate charging performance when the battery level is below approximately 30%.
• Many smartphones automatically reduce charging speed once the battery has reached a higher charge level.
• At around 80% battery level or above, charging may become significantly slower.

6. Check battery protection features

• Many smartphones include features such as optimized charging, adaptive charging or battery protection modes.
• These features may intentionally reduce charging speed or limit charging.
• If necessary, review your smartphone's battery and charging settings.

If your smartphone still charges too slowly

If charging performance remains significantly below expectations after following these steps, please contact our Customer Support at [email protected].

Please include the following information:

• Order number or proof of purchase
• Full shipping address
• Smartphone model
• Charging Module model being used
• Details of the power supply, including charger, output rating, connection method and cable used
• Please also indicate how much your smartphone charges over a specific period of time, for example: "The smartphone charges by approximately 10% within 30 minutes."

Summary

Slower wireless charging is often caused by temperature, power supply limitations, smartphone settings or high power consumption during use. In most cases, charging performance can be significantly improved by using a suitable power source, ensuring proper alignment and reducing the smartphone's power consumption.
