iPhone was charging only when off. Not recognized by iTunes [Mac] Replaced Dock Connector as suggested [Not Battery]. Still after replacement: • Still Won’t Charge from iMacs [3 different devices] • Tried 2 different wires [one fairly new] • Still Won’t Charge from adapter (used to charge only when “off” before the stopped charging and stayed that way after replacing connector) • When plugged to 3 different iMacs get same warning: “USB Devices Disabled Unplug the device using too much power to re-enable USB devices. In brief: No connection or charge improvements after replacing Dock Connector
Charging an iPhone requires a set of about 5 functional components on the motherboard. Any of these can become damaged, and the history of the phone may help to guess which one. In your case, there are two little filters near the dock connector that are required for USB detection and charging. If something happened to them then no matter what else you do, the phone won’t charge. With recent work near the dock connector, this is where I’d start looking. Troubleshooting and replacing components in the charging circuit line is possible, but requires specialized microsoldering. This is the kind of work myself and a few other people on here do if you’re interested in seeking professional help with a board-level repair. Jessa
You won’t believe this: I replaced the dock connector and battery, was going to check the charging circuits when, my daughter came home, exactly the same day we found a misplaced iPhone 3g [she has an iPnone 4s also]. I went to charge the 3g, and it did not charge-Nothing, dead. I thought to use her charger-cable and wow, it charged…… so then I thought, no, can’t be that 3 [3!!!] charging cables where messed up at the same time. No, that CAN’T be. So, I plugged the iPhone 4s to her cable - charger and IT CHARGED!!!! Unbelievable… by the way, one of the 3 cables what almost new. So, what are the odds? Grrrrrr……Anyway, I did not waste my time, nor your advice. I got the see the inside of an iPhone 4s, replaced a dock connector and a battery. Studied your advice and learned something because of it. Got some thrills out of that. Plus I bought some cool tools from iFixit. Very happy with this website-company and all you guys who gave great advice. I learned a lot. THANK YOU ALL. Next time, I will test the basics 4 times instead of 3. Jessa, con, OldTurkey, thanks again.
Have you tryed a battery. Sounds to me like a motherboard problem
My iPhone 4S was out of commission, until I bought a new charging dock. I’ve replaced it, and now the battery won’t charge.. Never had problems with it. Only the dock. It’s slow as heck, and my wifi has been greyed out. It’s about 2 years old but hasn’t worked for the past 7 months.
Hi guys, I have a problem with my iphone 4.it was water damaged and I used alcohol after I’ve done that it only turn on when its plugged in charger,I thought it was a battery problem so I replaced it twice but still it just get stuck on connect to itunes.can anyone help me please,I would be very happy for your help.
Yea… IPhone 4S is dead. I replaced the battery and it turned on after 3 long months of a using my old flip phone(which wasn’t as bad because of t9 texting).I was very happy but then I noticed that my phone still doesn’t charge.Is replacing the dock connector a good choice or is it a waste of time and money? I’m novice at fixing things myself but soldering if far out of my league. Phones jail broken also don’t know if that matters. Any help would be awesome , phones not under warranty and have nowhere else to turn.
Hi i have a ipad 4 64gb i plugged in a dodgy cable and it started smoking so took it off.the ipad carried on working until battery went flat and then wouldnt charge.ive had the charge port replaced so looks like a chip on the board has gone or the fpc charge connector on the board.Anyone know where i can get the connector from as this would be the easiest part to replace under my microscope.im not sure if i have a steady hand to be soldering the tiny chips lol Thanks in advance Dave
