My button was stuck, requiring a lot of pressure to get it to register anything. And even in that situation not always reacting. My battery life had been terrible. Charging for eight hours just for it to be at 60% in a matter of two just wasn't working for me.
Being that the power button required full removal of the logic board, I was slightly leery. But I followed the guides to the 'T' and my phone is like new again. The only issue I really encountered was putting the small screws back in holding the button in place.
Be sure to separate and organize all the parts you have to remove. Because if you just put them in a pile, you are asking for trouble. Personally, I put each step into its own pile so when I went back to the step to put my phone back together, I was just collecting the pile I needed and putting it back in the device. It made things go so much smoother.
