As explained in the "what hasn't arrived yet" topic, my phone rattles en creaks when it makes a sound. It just doesn't sound good. The iPhone 6 of a friend (same model) has a way better sound. So, i removed the loudspeaker, replaced it with a new one. And yet, no improvement. Now what? On iFixit, someone responded to the replacement guide, that his fix was the battery. A new battery, and suddenly his sound was fixed as well. Does anyone think this is an option? Because to me, replacing it is a very feasible option, as I'm planning to transfer all the iPhone 6 guts into a new white coated aluminium back housing. Therefor, I need to remove the battery as well, so why not replace the 2 year old thing? Any suggestions?
