Those caps are on the PP_GPU line and it is a very low resistance line, typically in the 10-20 Ohm range. Most meters will "beep" when set to continuity mode with that kind of resistance. So unless you are measuring <1 Ohm, I would say the readings are normal.

You don't really say what the original issue/problem was so I will just say that if you have fast battery drain, try a known-good battery first and then remove all peripherals and test them individually. If the drain occurs even with just the logic board (with a known-good battery and Lightning port), then you need to measure all of the PMIC & BB PMU lines.

So it's actually all the caps on that line my error I was wondering if 1 cap was burned out and acting as a wire to ground can this do that and the original issue was that it would kill new battery's as in new battery will only last a month before it's completely dead and not even a good phone can charge will die at about 50% and by the end of that day the battery is so drained it will boot loop but comes good with a good battery works fine for another month I have found that c2018 is a lot hotter than the rest and has a darker colour with a mark on pmic around it
