Gold grounding prong on motherboard affect battery life?

For all those interested, I do not have pictures. They were on a computer that the hard drive was corrupted on and I no longer have them I also sold the phone so taking new ones is not an option either. I'll try to make it as clear as possible though for people to follow. So, a formal DIY will follow in this post.

iPhone 3G/3GS motherboard grounding prong fix:

This worked out really nice for my situation because I fix iPhones quite a bit and as a result I have a lot of random spare parts lying around. You may not have the same resources that I did and if not you will need to be creative. In this case, I used a silver prong from that holds the camera down on the 3G and 3GS model phones. That is the only part you'll need.

The brass grounding prong on my motherboard broke completely off once when I was removing my motherboard to replace the battery. I couldn't find it so I put the phone back together like normal once my battery replacement was done. I noticed a sharp decrease in battery life and this is likely due to Peter's reasoning (accepted answer for this topic). I looked around to try and order the prong to no avail so I decided to improvise. I happened to have an extra camera tab from someone's phone I had that was almost totally smashed. It has a wider base at the end that the screw passes through so I figured it would be suitable to mount in the same arrangement as the brass prong and I would simply have to bend it up in the same orientation so that it would make contact with the inside of the bezel once the motherboard was installed. I cheated a little bit and used super glue at first so it would hold itself in place while I soldered it down. If you cannot solder it down I recommend holding it in place with something small and unobtrusive such as the head of a pen while the motherboard is on a flat surface and applying super glue to the top of the tab. Some runoff will occur and that will be what hold the contact in place. If you do it between the tab and the motherboard contact pad you run the risk of not having an electrical connection. That would defeat the purpose of this DIY fix in the first place. Once I reassembled my phone and fully charged my battery, the battery and antenna performance went back to normal levels. A good preventative measure for this issue is to be careful when installing your motherboard and not allowing that brass tab to get behind the bezel. It will get caught and that is what breaks them. If it does get caught apply some pressure to that lower corner once all screws are removed from the motherboard and it should clear the bezel and free itself. That's all I've got so let me know if there's anything else I can do.

I only used a camera hold-down tab because my gold prong broke. If yours fell off then I would recommend putting it back on where it went. If you can solder then this is the best method though you may be able to get similar results with superglue applied once the tab is set in place. You don't want to have glue between the prong and the contact surface. Let me know if you need me to clarify further. By the way, when I say camera hold-down tab I mean the tiny litte metal piece that the screw passes through to hold the camera in a 3G/3GS down. It may have a different name, I'm not sure.

Wanted to ask something else in relation to this question. My iPhone 3G 16GB is running a redsn0w jailbreak of 4.0.1 and it runs like crap. So many functions take so long to complete that it's almost a worthless phone. I have 3 other 3Gs (multiple iPhone 3G, not 3G S) that are also jailbroken on the same redsn0w 4.0.1 and they all perform perfectly fine including multitasking and also having the background wallpaper enabled. Could this issue also be related to that gold prong? If the phone is overloading the amount of power sent to the antenna, it is denying other functions of the phone the power they need to function properly?
