The repair was difficult, very difficult and time consuming. Mostly because the screws are tiny and are hard to work with, particularly putting back into the phone. The adhesive tape on the battery did not remove like the guide suggested it would, had to pry the battery loose from the phone which was very difficult. After replacing the battery and putting it all back together the phone now gets extremely hot (which is dangerous), has a weak cellular signal, and barely existent wifi signal.
Just take it in to apple for a battery replacement and save yourself the headache. I'm now out for the cost of this kit and will now have to buy a new phone since I voided the warranty by attempting this repair myself.
