Reason: ad image
you can solder the blank wire to the surrounding gril... cos its all connected to ground...

sorry to come back in an old topic (although certainly not a gone problem!)
My Iphone stop charging for months. I bought a new logic board and decided to fix it a couple days ago. I open it, took out the camera and because it was late and I had low light, I decided to wait until next day before disconnecting all wires and swap boards. Still, I left it charging (and the picture with the battery and the little red bar was on display)
next day for my huge surprise, the battery was 100% charged! so, I assembled it back and used the phone for a couple of days (I never changed the logic board, the phone still had the original one!)
When the battery was running low, I decided to put it on the charger again ... just to find the same old problem. the battery icon with the red bar eventually showed up and the phone wasnt charging!
I opened it again, press everything and put it to charge... no change, the phone doesn't charge at all. Ok, so I finally decided to put on the new logic board... after done, I put tha wall charger again .. and nothing, THE PHONE IS NOT CHARGING WITH THE NEW BOARD EITHER.
I bought the logic board from Ifixit, so I am guessing it is ok. So, I decided to use my voltmeter and read the battery levels. The reading is of 3.45 volts between the red and black wires which lead me to believe the phoe IS CHARGING, but somehow the logic is not working and the phone never change state, even if I do the hard reset.
My questions are:
1. What is the purpose of the white cable in the battery ?
2. Can we assume that the symptom indicated a problem in the communication board? (by the way, the phone NEVER gets hot)
3. If so, do you think your jumper solution will fix the problem?
thanks in advance for your feedback..
I have found two faults in iphone which results in no response.
1. Iphone goes dead while using normally.
2. Iphone goes dead while charging.
I think we had a confusion here!!
The solution of jumper i've given is of (1.)no power fault of iphone in which the battery does'nt drains!
& the second fault which occours due to wrong charger..(2.).is of power management ic in the logic board which gets short!! (APPLE, 338S0459)
in this case the board develops some resistance due to which the battery drains out completly.
These are 100% confirmed faults!!
Yeah & do remember that iphone has two seperate & different power management IC's for both the boards!! APPLE, 338S0459 for the logic board & 338S0289 for the commboard....
i tried but phone still dead
Mr francis i tried what you illustrated (the jumper thingy) but my phone is still dead..what could be the problem..?

Thanks franscis for found this solution on 2G board it works like a charm.
So, if the same problem happened on 3G board any idea which spot to make a jumper ???

Next, I orderd a fresh battery on ebay to replace my existing battery because I thought perhaps the battery was fried. I replaced my old battery (soldering and all) and though the iphone worked, as soon as I plugged it in to charge it, it began to glitch again.
Lastly, my phone was telling me that I needed to restore it. I did so and it didn't help. Though it supposedly restored my firmware, as soon as I plug in the phone, the glitching and heating reconvenes.
It's almost useless to ask, but does apple provide any kind of warranty on these?
Have power with charged battery
Please respond if this thread is still alive.
Ok. Se here is what I have. I have removed the battery and I am now powering the phone wit a completely charged Nokia 3.7v battery. EVERYTHING in the phone functions PERFECTLY. What I can't do: As soon as I plug in the dock connector to charge or to sync the phone shuts off.
So I can't do a restore to put my own info on the phone. Other than that, it WORKS PERFECT!
My question is this: could i get away with soldering the jumper as shown or do I need a comm board? ANY suggestions will be greatly appreciated!
Thanks in advance!
also lost white connector
I also did the same mistake to break the white metal pin connector.
Now I cannot solder the white battery cable to the board. So now, the battery wont charge anymore.
The connection jumper to the 6th pin of the board as described in the other picture is too hard to perform. it's requires a very accurate soldering and a very thin silver cable. or preferably thiner golden cable. also, there is not enough space to the solder dip.
Anyways, but what i did instead is to solder 2 very thin silver cables. One to the white and another to black pin and the 2 cables are sticking out of iphone from a small hole at the black bottom cover.
I plan to connect the white cable to the positive (+) terminal of the charger and the black to the negative (-).
I should be able to use the normal nokia chargers because they operate at 4.8 V and 500mA.
There are some nokia chargers that gives 800mA. I wouldn't use those because use nominal current is 500mA.
anyone have any idea about it?
or could I also solder the white cable straight to the 5V pin connector of the USB port of the iphone?
I will perform this tomorrow.
and come with pictures is successfull.
This is very risk and can be dangerous enough to explode the battery. !!!
