Correction: iPhone XS and XS Max Smart Battery Cases Have Larger Capacity Than Previous Versions
While reports today suggested that Apple's new Smart Battery Cases for the iPhone XS and iPhone XS Max have lower battery capacities than previous versions for iPhone 6 and iPhone 7 models, it turns out the new cases actually have larger capacities than the old ones when taking voltage into consideration.
The new iPhone XS and iPhone XS Max cases are rated at 1,369 mAh, lower than the iPhone 6/6s case at 1,877 mAh and iPhone 7 case at 2,365 mAh, but according to Rene Ritchie, there are actually two such cells in the case.
As a result, the new cases run at a higher voltage that yields a total of 10.1 Wh of energy compared to 7.13 Wh for the iPhone 6/6s case and 8.98 Wh for the iPhone 7 case.
Paired with Smart Battery Cases, Apple says the iPhone XS gets up to 33 hours of talk time, up to 21 hours of internet use, and up to 25 hours of video playback, while the iPhone XS Max gets up to 37 hours of talk time, up to 20 hours of internet use, and up to 25 hours of video playback.
Of course, real-world testing will prove more valuable than tech specs, so we'll see how the new cases truly stack up in the coming days.
Apple introduced Smart Battery Cases for the iPhone XS, iPhone XS Max, and iPhone XR yesterday. All three are priced at $129 in the United States, with deliveries and in-store availability slated to begin this week. Apple says the cases are not compatible with the iPhone X, but results have varied so far.
