Picture of Shorten iPhone 5 Lightning Cable
I wanted to shorten one of my iPhone 5 lightning cables for my car charging purposes so I thought I'd give it a whirl.  I'm new a soldering and haven't done anything like this previously with this type of cable so I wasn't sure it would work.   I tried this twice, the first time it didn't work, the second time it did.  I wrote this instructable on the fist attempt so read though carefully as I have indicated where I made the error.

The reason I did this was because I also made a custom usb chaging port on the left side of my car steering wheel (which is where my phone mount is) and I did not want it to be overly long.   In the end it became about 10cm long and works great.

Step 1: Things you'll need and time

Step - 02.JPG
Time for project: As Im new to this, it took me about 2 hours (including time to document the experience).

Things you'll need:

1. USB Cable $21
2. 30W Soldering iron or better $20
3. Helping Hands (Aligator clips mounted on stand, Radio Shack $20)
4. Sizzors
5. Wire cutter/stripper $5-10
6. Shrink tubing $6
7. Fine Solder  (I used 0.6mm for this project) $7
8. Electrical Tape $1
9. Lighter or heat gun. $1 - $50
10. A Pin (this is not needed for second attempt)

Step 2: Cut and Strip wire

Use your wire cutter to cut the cable.  Cut to length with the intention of stripping 2 - 3 inches off each side and plan for the stripped portions to overlap in the end to get the cable to the length you want.

Strip off the exterior white sheath.

You can get heat shrink without writing on it (if that matters to you) over at http://FixaCable.com.

I've been using their repair kits to prevent my kids from destroying so many Apple charger Lightning cable connectors. Thanks Apple. :-/

Works like a charm and its a cheap fix. Cheers.

BTW. The lightening cable itself is a low voltage data transfer cable. It is a shielded and individually grounded three conductor low voltage data transfer cable. Similar to Ethernet, telephone, or industrial signal cables.
Individual components of cables are all useful and necessary

I agree with you that all components to cables are there for a purpose. i have been using this cable I made since I posted this instructable with no ill effects on both my iPhone5 and iPhone6. As with any electronics, modify at your own risk.
Individual components of cables all have a function and are all necessary for the cable to perform as designed.

The "tin foil" is called Mylar. Both the Mylar and the braided outer jacket are the cable's shield. These shields eliminate any electrical interference "noise" from adversely effecting the circuit by interfering with the low voltage transmission of data. Without the shields, induction from nearby conductors and circuits can interfere and even prohibit the flow of electricity/data through the cable. Induction also causes a change in voltage and current to levels that may damage both the cable itself and possibly any device plugged into it.
Both the Mylar and braided are important components of any signal/information carrying cables. Cut them off, or not properly splice them, and you could experience adverse reactions, or even damage.
This is a risky procedure for anyone not sufficiently experienced in electrical practices with knowledge of electrical properties/limitations. I wouldn't risk damaging my $800 iPhone just to make a $10 cable shorter.

FYI:

The braided sheathing and the tin-foil are both there for good reason; they shield the cable and other devices from interference. Also, the nylon within also serves a valuable purpose as a "strain-relief" to help prevent the cord and your connections from being pulled apart.

Agree these "extras" are always there for a purpose. But are not 100% necessary for it to function.

I used your instructable as a guide for a more involved repair of my cord. It ain't pretty, but it works.

Great! Can't see picture clearly. I agree this isn't the cleanest method. I've been toying with the idea of opening one end, disconnecting and reconnecting so all connections are hidden. Maybe I'll give it a shot one of these days. Thanks for comment!

I updated this instructable with a method that made it work properly. Cheers.
