- If you have a case on your phone, ensure that it is wireless charging compatible, as some thicker cases can interfere with charging efficiency.
5. Power Source
The power source of the wireless charger also plays a vital role in the charging process. Connecting your charger to a low-power USB port, such as those found on laptops or older device chargers, may limit the output.
Recommended Power Source
For optimal performance, here are some types of power sources to consider:
- Wall outlets using Qualcomm Quick Charge adapters.
- High-speed USB ports capable of delivering the required wattage.
6. Background Processes
Smartphones running numerous background applications can experience slower charging times. These processes consume battery power, meaning that your device is charging and discharging simultaneously.
Reducing Background Activity
To improve charging speed, consider the following strategies:
- Close unnecessary apps before placing your phone on the wireless charger.
- Activate battery saver mode, if available on your device.
Optimizing Your Wireless Charging Experience
If you’re tired of slow wireless charging, there are several actionable steps you can take to optimize your experience.
