The new iPhone 6s and iPhone 6s Plus are set to be released before the end of the month. Buyers who want to protect their brand new phones with an AppleCare+ support plan will need to shell out an additional $30, CNET reports.

When accessing the AppleCare+ page for the new iPhones, the price of $129 is shown as well as what comes with it. The iPhone 6 and models below it still retain the $99 price for AppleCare+.

AppleCare+ provides a total of two years of protection for iPhones. Apple will assist customers with repairs or replacements for their iPhone for one year with the default warranty. With AppleCare+, an extra year of warrantied repairs or replacements will be given. Additionally, only 90 days of free phone support is offered with the default warranty, but with AppleCare+, customers can call for free for two years. Apple will also replace two damaged devices within the two years for $79.

The $30 increase for AppleCare+ seems puzzling at first since very little was changed from the iPhone 6 to the iPhone 6s. The two new features that are likely responsible for the price bump are the taptic engine and the 3D Touch feature, according to MacRumors.

The taptic engine inside the iPhone will power the 3D Touch feature introduced in the iPhone 6s. 3D Touch will react differently based on the amount of pressure. A user can perform a light tap on a message to get a quick view of their email or a heavier tap to get a full screen view of it. 

The Apple Watch also uses the taptic engine to power its Force Touch and there has already been problems with it. Since the iPhone 6s has a much larger taptic engine with moving parts, it could also run into problems, so this might be why the AppleCare+ price was increased.
