will not haveing the grounding bracket installed prevent charging the phone? or any other issues?? basically what’s it important for.

I just got one in that had that bracket missing. The phone would only boot half way thru with out it. It helps hold the connectors in tight. Once I replaced it the phone worked fine. See if this part in step 11 & 12 is what you are talking about: iPhone 5s Logic Board Replacement

You have to specify which one. Some of those brackets are not just for grounding, they actually conduct RF signals. If those brackets are missing, you will lose reception.

Should be fine, If you have any doubt you could insulate with some electrical tape to make sure there is no short between the motherboard/housing/underside of screen.
