Just like the iPhone 6s, Apple more than likely made the battery a bit smaller to allow for the new parts needed for the Taptic Engine and 3D Touch technology. With 3D Touch, the handsets can distinguish between a quick tap and two different longer presses. That will open up a number of new gestures and other shortcuts that can be used in iOS and by third-party app developers.
Even with the smaller battery, Apple is advertising that the iPhone 6s Plus will offer the exact same battery life as the previous handset. Apple was likely able to compensate for the smaller cellby making the new A9 chip more power efficient and improving power consumption in iOS 9.
Along with the 3D Touch technology and thefaster A9 processor, the iPhone 6s and iPhone 6s Plus will offer a number of camera improvements including support for the interesting Live Photos feature. Both models will also sport 2GB of RAM – double the amount found in the previous generation of iPhones.
Each handset will be available in four different colors silver, gold, space gray, and rose gold. The phones will be made with more durable 7000-series aluminum found on the Apple Watch.
Apple is also offering an interesting new iPhone Upgrade Program. You can read more about how that works here.
Preorders kicked off more than a week ago on Apples site. If you place an order today, most phone options are slated to ship in three to four weeks. If youre looking to snag a new iPhone on launch day, this Friday, Sept. 25, you can also head to Apples site and possibly make a reservation for a particular model.
