Right now we’re tracking a number of discounts across most of Apple’s official case lineup for iPhone 7/8/SE, X/S Max, and 11/Pro/Max. One of our favorites is from BuySpry via Walmart with the iPhone XS Max Smart Battery Case in White for $49.99 shipped. For comparison, it originally sold for $129 and goes for around $109 at Amazon right now. Today’s deal is $15 below our last mention and is the best available. If your iPhone XS Max is starting to not last all day due to an aging battery, this case can help remedy that. Apple claims it adds up to 37-hours of talk time or 20-hours of internet use to your charge, and it supports both USB Power Delivery via USB-C to Lightning or wireless charging.
