Apple Releases $99 iPhone 6s Battery Case, Promises 25-Hour Runtime
If you've ever shopped around for a third-party battery case, then you know you're typically looking at around $20 to $40, depending on the brand, battery capacity, and other features. At $99, Apple's Smart Battery Case is predictably more expensive than the bulk of options out there, though to be fair, the price premium isn't strictly what some people refer to as an Apple tax.
When plugged in, iOS will display separate battery charger indicators for the case and iPhone. Third-party case makers can offer similar functionality through a separate app, but not on the lockscreen the way Apple's case does. It's a small convenience, but a convenience all the same.
Apple isn't saying what capacity battery is inside its case, only that it increases talk time up to 25 hours, Internet use by up to 18 hours on LTE, and video playback by up to 20 hours. Not bad, if you can stomach the price premium and the unsightly bulge on the case's backside.
