Chosen Solution
I dropped my phone and cracked the screen. A small chunk of the white part came loose so I put steri strips over it to hold it until I get a replacement glass ordered. I have procrastinated far too long because it was still working perfectly until a couple days ago. Now the screen sometimes goes blank and it suddenly stops working. It will say there is only a partial charge but as soon as I plug it in it says 100% charged, and the apple sign pops up and it will work again. Do I need to replace the whole LCD and digitizer too (not just the screen) or does this sound like the battery has seen better days anyway?
iPhone screens are always replaced as a whole, never separate these days. Whole display assembly and battery needs to be replaced.
