Apple has quietly launched a Smart Battery case for the iPhone 6 and 6s, which it says can offer up to 25 hours of increased talk time.

The case also extends the devices’ battery life up to 18 hours for Internet use on LTE networks and up to 20 hours for video playback, according to Apple’s online store. “With the Smart Battery Case on, the intelligent battery status is displayed on the iPhone Lock screen and in Notification Center, so you know exactly how much charge you have left,” the tech giant explained.

The case spells good news for users desperate to extend their battery life but unwilling to purchase Apple’s large-screen iPhone 6 Plus and iPhone 6s Plus, which offer up to 24 hours of 3G talk time.

Without the Smart Battery case, the iPhone 6 and iPhone 6s offer up to 14 hours of talk time on 3G networks, up to 10 hours of Internet use on 3G and LTE, and up to 11 hours of Internet use on Wi‑Fi. HD video playback is up to 11 hours.

Just a few months after the tech giant unveiled its iPad Pro and new iPhones the Apple rumor mill continues to spin full speed. Citing sources with knowledge of the plans, 9to5Mac.com reports that Apple is planning to unveil its second-generation Apple Watch at an event in March 2016, with the new Watch shipping by April. The Cupertino, Calif.-based firm has also been working on a new “iPhone 6c” with a 4-inch display that could make its debut at the March event, according to 9to5Mac.com.

Apple has not yet responded to a request for comment on this story from FoxNews.com.
