Apple iPhone 6S sports a 1715mAh battery; 6S Plus includes a 2750mAh battery

At Apple's 'Hey Siri' event saw the launch of the iPhone 6S and the iPhone 6S Plus. While Cook announced most of the features of the phone, one critical element was left out of the announcements. Battery capacity.

According to a report in MacRumors, the video where Apple Chief of Design Jony Ive is explaining the 3D Touch feature, in one frame, you can view the battery capacity in the blown out view of the iPhone 6S. The phone has a 1715mAh battery pack which is lower than the 1810mAh battery pack we had seen on the iPhone 6.

Similarly, MacRumors has pointed out that the iPhone 6S Plus comes with a 2750mAh battery capacity as opposed to 2910mAh battery that was seen on the iPhone 6 Plus.

The lesser battery capacity can be attributed to the fact that Apple had to cram in more gadget circuitry for its 6S and 6S Plus models thanks to the 3D Touch feature. There is the taptic engine which will respond to force touches in the iPhone 6S/6S Plus.

However, Apple claims that the battery life one can expect on the 6S and 6S Plus to be on a respectable side. With the iPhone 6S giving a 3G battery life of 14 hours and iPhone 6S Plus claiming a 24-hour battery life. Apple claims that it will incorporate battery-saving features on iOS 9, the newest version of iOS with which the new phones are expected to ship.

iOS 9 is expected to release on September 16 and claims to have battery saving feature for all supporting iPhones.

One certainly needs to takes Apple's claims with a pinch of salt as the new phones come with a completely new touch interface, higher megapixel camera with features such as 4K video recording and Live Photos, which can be potential battery hogs. We will only find out the true battery life once the phones are out.
