Iphone 5S schematics Different Hardware versions?

Hi all,

I am trying to troubleshoot my daughter’s 5S, which got dropped in water, and now had a short between pins 1 and 3 on the battery connector.

I had downloaded a schematic for the 5s a while ago, but didn’t need search capabilities, to find component by name on the PCB diagram.

I found one last night which is searchable, but it seems as if the PCB diagram is different than the actual PCB layout of the phone, as well as the diagram in the original PDF I downloaded.

Did I grab the wrong PDF for the searchable one? Are there two hardware versions of this phone?

Thanks in advance…Eric
