Docking port damaged or shorted out

While my iPhone was docked in my Bose sound dock seriesII, a nearby glass was spilled and some liquid got into the docking port area of the sound dock and the iPhone.

I've followed all the instructions here on the site, took the phone apart except removal of the battery. Dried all componentes out, everything clipped back together. When I plug it in using the pwr cord, the phone vibrates constantly and the battery charge signal turns on & off. Its like the phone receives the signal to charge, but it won't stay steady, off on off on...the phone stays on, only the charging process doesn't activate.

Could the liquid have damaged the docking port on the phone or the logic card too? Is the phone repairable?

When hooked to the computer, nothing happens, no charge, no vibe, no recognition from the computer.

All the phone functions work, ipod, wireless signal good, cell signal good, ipod functions well, just won't take the charge or be recognized by the computer. ~help~

The computer USB port generally doesn't supply enough power when batteries are kaput to charge/be recognised. Seeing a phone "cycle" in quick bursts on and off is also a sign of a dead/dying battery ( not enough power to get into boot mode) as the connection for the battery is about an inch from the bottom of the iPhone I think you can assume it has liquid damage. The vibrate motor being directly above the battery connection may just need a good clean. I would change your battery (cheapest option) and reassess. You may still need a new dock or it may be that you've damage to the logicboard, but try the cheap option and see. Good luck

So, I should order a new replacement battery and new dock port then see what happens? All functions of the phone seem ok 100% except the charging. If the logic board was bad, wouldn't the phone not function at all? Just curious, I'm new to this, first time digging into an iPhone internals.

Thanks for the help.


If the problem is isolated ie one teeny gold connection or component the phone will still work. I have few phones that won't acknowledge charging but actually did charge.

Swapped out a battery yesterday with very small amount of water residue on board, dock indicator was pink, battery connection looked good... when I looked at the battery- the underside had collected water into the actual connection/ taping.impossible to see from above! Phone couldn't boot, and not enough energy to make iTunes detect. A battery is $5? Most common fault... Easy fix!!!!


+ the voice of experience, I like it


Ps- bit of a clean with iso removed green corrosion from battery area so don't forget that too or you may find a few months down the line you've rusted out!

I received the replacement battery and dock connector, cleaned and installed new far so good. Everything seems to be working as advertised. Plugged in now, taking a charge like it should. All functions work, phone, iPod, apps ect...

Thanks to all who advised me what to do and this web site for some very helpful info, parts and quick shipping! You all definately saved me some time and money. Being in Italy, the local techs would have probably kept the phone for a month and would have charged me 2x the amt I spent to fix it myself.

Thanks again!
