    If you restored from a backup to the other iPhone after you placed the logic board in it then you may have restored the problem. A rogue app and/or setting can drain a battery quickly even when not in use. With that in mind, I recommend you set up the device as new if the above applies.

    My general advice is thus:

    Delete the Facebook app.
    Disable background spp refresh.
    Turn off Bluetooth if you don't use it.
    Reduce your brightness.
    Check the battery section.

    Background App Refresh is a good thing. It saves more battery than it uses. It helps apps run in the background more efficiently.
