Excellent Battery Life
Apple is well known for delivering excellent battery life with the iPhone. And with so many improvements expected with the iPhone 6s, you can count on the iPhone 6s and iPhone 6s Plus to deliver outstanding battery life.
In addition to the new processor and new Qualcomm chip, Apple's making some big changes to its iOS operating system. One of iOS 9's most exciting features is a tangible one hour battery life boost for iPhone models. That's huge for older phones and it should help the iPhone 6s secure solid battery life.
We're still not sure how big the iPhone 6s' battery is going to be but we wouldn't worry too much about it at this point. With an efficient processor and software tweaks, both iPhone 6s models should have something to offer.
