My first iPhone 5s battery change! - I had a totally dead 5s, it wouldn’t charge, only showed a dim screen and no logo, I suspected a dead battery. I watched the battery change video on iFixit, it looked simple enough but as usual nothing ever goes exactly as planned. For some reason the screen refused to be removed using the sucker, I ended up going round the screen with the point of a small penknife to ‘break’ the seal of whatever was holding it. The Home button cable then popped off almost without any help from me - I was dreading putting that back on!
