Using these cases will give you a huge battery improvement. For example, the XS version boosts your talk time on the iPhone XS up to 33 hours, while internet usage rises up to 21 hours and video playback up to 25 hours. It was designed specifically for use with the iPhone XS too, meaning it supports Lightning accessories like the EarPods with Lightning Connector, the Lightning Digitial AV Adapter, and more. It also still works with CarPlay via the case's Lightning port.

The cases for X series devices are Qi-enabled meaning you don't lose out on the wireless charging function of your phone. Just lay it down on your charging pad as you normally would and both the case and phone will juice back up. A USB charger featuring Power Delivery can charge this case even faster. Fortunately, Amazon is also having a sale on a bunch of charging tech today, so you can add some other battery-based bargains to your cart while you're there.

We shared a review of Apple's Smart Battery Case for iPhone XS last year which can help illuminate this model's features and downsides as well, plus a guide on how to fast charge your Smart Battery Case.
