Accidentally ripped one of the Wifi grounds off of the motherboard of an iPhone 6, yet the Wifi still seems to function just fine. Is there any adverse effects or latent damage that will occur later on? Here is a picture of the damage http://imgur.com/a/i4QOR
In my opinion at worse a decrease in signal strength leading to a decrease in battery autonomy. And at best nothing really noticeable. You can live without it - a bit like loosing a toe. You’re less grounded but otherwise fine.
