With the iPhone 6s and 6s Plus officially going on sale and delivering to pre-order customers over the weekend, it’s just a matter of time before you smash your display to pieces and drain your battery’s capacity. While some screen breaking and defective batteries might be covered under AppleCare and the 1 year hardware warranty included with all iPhones, otherwise you’ll need to refer to one of these handy guides from our friends at iFixit.

Today iFixit posted guides for both the iPhone 6s and 6s Plus. That includes a guide for replacing the iPhone 6s battery and another for its display, as well as the same guides for the larger iPhone 6s Plus model (battery and display).

For the most part guides for the two models are the same, save for an extra screw that needs removing from the panel holding in the front panel assemble cable bracket.

Head over to iFixit to check out the free guides for both the iPhone 6s and 6s Plus.
