This kind of warning (sometimes called "Slow Charger" or "Charging may be slow") appears from time to time while charging the iPhone. Many people find the message confusing. So today's article sets out to unfold what this message means, the reasons behind it, and a remedy for this message for the iPhone.
What Does that Mean if "Slow Charger" Is on iPhone?
In general, charging is likely to be slow if the iPhone realizes that the charger is inadequate with respect to power input. The reasons usually include:
Old charging adapter of low power (i.e., older 5W adapter)
The use of a non-genuine or poor-quality charging cable
Charging simply through a USB port, e.g., from a computer
The charging port is built up with dust or dirt.
What Are the Causes?
Apple products work best with MFi (Made for iPhone) certified hardware. So if you happen to use a cheap third-party cable that is not MFi certified, this is the kind of notification you may receive.
How Will You Solve This?
1. Use the original charger:
Using the original Apple adapter and cable has been shown to decrease the chances of occurrence.
2. Buy an MFi-certified cable:
In case you are using a third-party charger, ensure that the charger is MFi certified. Do remember to check for "Made for iPhone" written somewhere on the package.
3. Clean charging ports and ray:
Dust or dirt accumulated in the iPhone's charging ports may affect the charging process, so clean them gently using a soft brush or toothpick.
4. Fast charger:
Use a minimum of a 20W USB-C Power Adapter, fast-charging your iPhone, especially from iPhone 8 models onwards.
5. Change the cable or adapter:
If the warning comes up again, try a different cable or adapter.
A slow charger warning means the charging speed of an iPhone is slow. This can have long-term effects on battery health. Always use good-quality original accessories for this purpose.
