iPhone 4 won't charge!

Honestly, I would try the following:

- I would try changing the battery.

If that doesn't fix it:

- I would change the charging base itself.

Same issue I had. My friend had just replaced her iPhone with a version 5 and two days later needed to download the old iPhone 4 - but somehow the battery completely and utterly failed in those two days - shady...

Anyways, I did a quick search online and found that it's quite easy to avoid the $79 Apple fee and get a new battery online. Overstock dot com sells them as do lots of places (~$12).

iFixit.com doesn't sell the battery, but they sell the iPhone 4 Liberation Kit - which is useful if you don't own a tiny Phillips-head screwdriver. You'll possibly need the pentalobe screwdriver, but not necessarily - check. Even if your external screws are the weird pentalobe-head, the internal battery screw will be tiny Phillips.

The problem could be anything, it could either be water damage or your charging pin could be damaged (Due to any physical or any other type of collision). or it could either be:

Charging Connector is water damaged

Dry solder of connector pin

Pins doesn’t make contact with board

Faulty components.

Anyways here is a blog that has explained this thing in a step by step manner, for you to know how can you overcome this issue, i hope it works for you.

My iphone 4 had the same problem. It says that it is connected and it can transfer data but it doesnt charge. I had the battery replaced and therefore I was able to retrieve photos etc which is good. Even when it is attached to the wall socket it doesnt do anything.

I think it must be the dock socket. Ill replace that and see if that fixes it.

I have the EXACT same problem I called apple and here's what's going on: My phones battery is like done. The battery's condition is ONLY 30% so when Ibplugged it in over night, ok ok right now it's 8:49am but my battery is just 18%! Here are you options because the battery isn't going to get better.

•Get the battery replaced

• Buy a new phone or upgrade to a higer generation

Hope everything turns out well for you. Hopefully same with me.

Change the dock connector the issue happened after the item was plugged and unplugged from a cord. The chances are that it damaged the dock connector pins.

So I just had a problem with my iPhone 4 charging. When I plugged it in, it would make the charge jingle but the plug would show up in the battery like it was fully charged (I think it may also show up when charging with unsupported charger) instead of the charging spark (or lightning bolt thing) that usually shows up when charging. Lucky for me I had a spare iPhone battery lying around and swapped it out. This was after I tried turning my phone off multiple times and doing a hard reset, which didn't fix the problem. Anyway, the new battery fixed the problem, and now it charges just fine. Im not sure what was wrong with my old battery, it is a few years old, but it seemed to hold a charge just fine before it just stopped charging. If anyone else has this problem I would recommend trying a hard reset first and then if that doesn't work try swapping the battery before you go messing with the dock connector since it is a lot easier.

U have to turn the phone completely off let if charge in the off mode for 20 mins. U will receive full charge.

I am going through the same issue. I believe their forcing us to upgrade.

My iphone 4s wouldn't charge either and I thought it was going to need a new battery or something. My husband looked at it and said the cord was not making good connection with the port. He plugged it in and set something under the cord to elevate it so that it was laying just a little elevated. Immediately the green light and the charging symbol came on! Now my phone will charge very quickly as long as I put something under the cord to elevate it and ensure a good connection! For mine a wooden coaster I have works just right.

This is a sign of an charging doc connector that is about to die.

Remember the charging ways for charging from a USB connector and charging from the wall are not the same.

So if you notice: You can charge your phone via notebook/computer but not from the wall or vice versa, than you know its your charging doc that needs replacement.

Weird part is I had this problem, it went away, and now it's back!

Definitely seems like maybe something loose.

Also has intermittent issues with locking up of the touch screen, and the volume.

Time for a replacement Otter Box and trip to the repair shop.

Using a set of tweezers, I cleaned the dock socket and it still didn't charge. I replaced the dock socket and now I have a new battery and a socket for Australian$70. My phone is now back in action.
