Great Guide - Thanks!
My repair went off without a hitch. I used iFixit's part-only new replacement battery (which showed full capacity after installation) and my wife's nail polish remover as a solvent to loosen the adhesive. I poured a few ml's into each slight depression (i.e. under each battery pair), left that for around 20 mins to evaporate, then poured a tiny bit in again and gently pried each battery out with a spudger.
PS - I see the guide lists a T7 Torx as one of the needed tools, but I can't see where that would be needed in this repair. T5, T6 and P5 were all I needed.
Is adhered to screw beneath, so lift firmly and slowly.
I have the same question - clearly one speaker is buzzing while the other sounds fine. Why replace both?
I used this tool on 2 successful screen replacements - BUT on the third time, the force did in fact separate the glass from the plastic, so I'd suggest inspecting first, and using with care.
I could not get a phillips #000 to release these, but a phillips #00 did the trick perfectly. South African version of the phone, if that makes a difference.
