"Charging is not supported with this accessory" error
I recently washed my phone through an entire laundry cycle (!!!!!). After taking it apart and letting it rest in rice for a week, we turned it on and all functions worked perfectly, but the battery wouldn't hold its charge. So I installed a replacement battery, and since then, I get the above error, but the phone will slowly charge despite the error (1-2% per hour) up until around 65%, then slowly lose charge even when still connected to the charger after that. iTunes recognizes my phone just fine. Is this a battery issue or a dock connector issue? Any suggestions?
welovesnow, the first thing I would suggest is that you clean your phone. The rice is a great first step, but it will not fix your phone, nor will it prevent corrosion damage which might occur later on. Use this guide to clean your phone. It was written for a 3G but it will still pertain to your phone as well. The repair guides for your phone are here. After that you want to check this "There is really no a surefire way to say which part is the one that gives you the problem. I would recommend that you start it systematically. Clean the dock connector, make sure there are no broken, bend or corroded pins. If after that you still have the same problem, replace it. Re-evalaute for any further damage. Oh yes, one more thing, make sure that you have the right USB cable. I accidentally used a wrong one, and got the same error :-) Anyway, hope this helps, good luck.
I had the same problem with my iPhone 4 (not 4S) and I thought it was the battery at first but a new battery didn't fix it. I spent hours and hours looking for a solution and tried everything. The phone was out of warranty so I had to get my hands dirty and take the risk and changing the parts myself. A new charging cable didn't help either. Then I changed the Dock connector and the issue was sorted. Please follow these steps. Buy the following parts:
I think all in all cost me about £30+. I bought the battery just in case it was the battery and I was desperate to get the phone working. By the way I bought a new set of tools as I read that the ones that come with the parts are useless. I used the following YouTube video to change the dock connector - it took me about 15 minutes to change it and a bit of patience! I didn't use a wrist band to earth any static - you should be fine without one.
The tricky bit is reconnecting the Home button points and removing the rubber casing from the existing mic to the new dock. A pair of tweezers like she mentions in the video is also worth getting hold of. I didn't use one, but wished I had one when I was reconnecting the Home button!
I remember I dropped it a couple of times (inside the case). It is said that the connector is very sensitive to water so keep it away from water! After changing the parts its like new!
Hope this helps and it will save you lots of money! At your own risk!
