    VBATT SENSE and PP BATT VCC are "signals." They may be I/O, sensors, even power from what you have shown. They go to something on the rest of the schematic. What is it that you do not understand?

    The circled numbers may be anything. In context, they may be pin numbers on connectors.

    Thanks for your response,
    That's right they go somewhere in schematic, I did followed and it goes to two IC,

    non of them have this pins on them,
    so what do they stand for?

    Without seeing the rest of the schematic, that is impossible to determine.

    How can they "go to" an IC if the IC has no pins? Please express your question in a more clear manner.

    They go to an IC!
    The IC doesn't have any pins numbered 23 or 50.

    Any idea?

    Yes, I agree with the previous comments. It could be IC pin. its a connection going to IC

    Have you tried searching for that label? Also dont´t forget that the page numbering in a pdf can easily be off by one or off by many, relative to the original document.

    Other things it could be. That part of the schematic is missing. Or that connection has yet to be implemented. why it would be on the schematic, no idea.

    This:
    upload_2019-3-15_3-39-38.png
    is the one end of a bus (notice the darker line) that has signals BATT U3 300-A1 ...BATT U3 300-E1. The schematic happens to show and label each pin. The C1 signal goes here:
    upload_2019-3-15_3-44-13.png

    Note that C1 goes to multiple pins that are individually numbered C1...C3.

    Those small numbers on the bus or signal lines that exit the page are probably page numbers. Except for the multiple pages, there is noting there that isn't in the free version of EAGLE. One may simple decide not to show that information.

    I noted that, thanks for pointing out, but still it's not related to that,
    And this tool is dongle for iPhones schematics,

    In AutoCAD Electrical those numbers would be line numbers. So, to me, those are Line 23 and Line 50. Again, in AutoCAD Electrical each page has different set of line numbers, for example, page 1 would have lines from 1 to 100, page 2 would have lines 101 to 200 and so on. So lines 23 and 50 will be unique in the document and can only be found on specific pages. Does your document have line numbers?

    P.S.: Looked at the "big" png, yes, that is AutoCAD sheet.

    Has billymayo got a new name? This thread is very reminiscent of how he posted.

    I don't think so. Probably just multiple inputs to the IC to enable higher input/output currents.
