Apple's has finally released battery cases for the 2018 iPhone models, including the iPhone XS, iPhone XS Max, and iPhone XR. You can charge these battery cases in several different ways, including fast charging and wirelessly with Qi-certified charging mats. You can also do this in a more traditional way using a regular Lightning to USB cable and charger. Here's how to do this.
Note that we used an iPhone XS for this guide. If you have an iPhone XR or iPhone XS Max, you're going to need the Smart Battery Case for your specific model.
Products used in this guide
- The case: iPhone XS Smart Battery Case ($129)
- The connector: Lightning to USB Cable (2 m) ($29)
- The power: Apple 5W USB Power Adapter ($19)
How to charge your Apple Smart Battery Case
Plug in the power adapter. Apple's 5W (mentioned above) or 12W USB Power Adapter will work.
If you're unsure of what Apple adapter you have, you can easily check by taking a look at the bottom of the adapter. It will say the wattage number in a square. You can also use a third-party USB power adapter.
Plug your Lightning to USB Cable into the port on the power adapter. Then plug in your Smart Battery Case on the Lightning end.
If your phone is inside the Smart Battery Case, the iPhone will charge first, and once it reaches 80 percent, the Smart Battery Case starts charging. You can charge the Smart Battery Case on its own. The light on the inside of the Smart Battery Case is solid red color while it's charging and green when it's fully charged.
