iphone 4 water damaged not recognize battery says 100 and searching new ios , any

On March 27, 2015, Posted by , In iPhone, With Comments Off on iphone 4 water damaged not recognize battery says 100 and searching new ios , any

I have an iphone 4 Along with water damage. Looks like it works. IF you plug into the wall, the phone turns on but battery is not recognized. It shows as 100% and the phone says searching. Ive already tried replacing battery already.


most of the liquid damage was concentrated in this area
/

Any suggestions would be appreciated.

    Does the phone start up Along without charger? I guess you have a short between Battery + and – terminal. Pls check it and post reply!

    phone will turn on for a couple of seconds if connected to computer then turn off.

    Which one is + and -? I tried checking the red and yellow dot those seem to be shorted somewhere. They have the same connectivity at the capacitor.

    EDIT:
    Im assuming the yellow dot is + and the red dot is -?

    OK so I took apart a broken battery and yes those pins are +/-

    They are shorted. I tried removing a couple of caps but same problem persists so I put them back. Any idea what to look for?

    Replace this Cap if shorted.title=smile

  5. RandikPixie says:

    Ive taken the cap out. +/- still shorted.

    so I just put the cap back.

    Why do all remove caps and other stuff Along without a plan?? title=frown

    – The yellow dot on your photo is +
    – Give external 3.7-4V to the board and check what gets hot. Then you have your fault!

    Its possible that your LED-Driver IC is shorted, i had this often after water damage in this area. This part is under the metal cover near the antenna connector in the corner on the board.

    Pls check only which part gets warm before you remove anything, you can destroy the board easy Along with weird experiments!

    Could a battery work or it wants to be connected to the wall? IE. an old charger say 3.6V and I take out the circuit from an old battery and connect it to that?

    Use a professional power-supply! Then you can see the the current and regulate it slowly…

    I just used a battery and it started sparking at an area. I quickly unplugged it. Kinda obvious where the short was…
    Replaced the capacitor. Battery is charging. Or so it seems. Well see.
