Some users who have bought Apple’s new Smart Battery case for iPhone XS, iPhone XS Max and iPhone XR are reporting that they are seeing a drop in maximum battery capacity after they started using the battery cases.
Apple explains Maximum capacity “as a measure of the battery capacity relative to when it was new. Lower capacity may result in fewer hours of usage between charges.”
A Twitter user reported to Rene Ritchie of iMore that he is seeing a drop in battery capacity after using the new Smart Battery case for his iPhone XS, and is wondering if it is bad for internal battery.
@reneritchie Do you think Smart Battery Case is bad for internal battery? I just started using it and within 3 days, my iPhone Xs’s battery maximum capacity dropped from 98% to 95%. Then after 4 days, it dropped to 94%. Never had this bad decreasing. pic.twitter.com/v2i9osmkw6

While Rene doesn’t seem to be facing the issue as his iPhone XS battery maximum capacity is still 100%, another user reported a similar issue.
Same issue here. Looks like I’m returning it. My case is already starting to peel around the edge of the case. Not happy. pic.twitter.com/oiBWzCkHRL

Ricardo also reported a peeling issue around the edge of the case, and plans to return it.
It doesn’t seem to be a widespread issue. Some of the iPhone users who bought the Smart case aren’t facing the issue like Rene. So I wouldn’t panic at this stage, but if you have bought the Smart Battery case for your iPhone XS, iPhone XS Max or iPhone XR, then you might want to check your iPhone battery’s maximum capacity using the Battery Health feature that Apple had introduced in iOS 11.3. You can check the Maximum Capacity by launching the Settings app, and navigating to Battery > Battery Health. If you are facing a similar issue as Ricardo and dkcblog then you might want to report the issue to Apple so they can investigate it.
