/diy/ - Do It Yourself

Another random question- why do these iPhone lightning cables crap out after 6mos or a year? Even the OE and $35 Tuff Cable do it. The end of this orange one reads ~4.8V just like a good white one so it has power.

I’m trying to play with the DC amp function. This was one of the cables that crapped out after some use but I was trying to get it to work a couple more times instead of destroying a good cable. Interesting part is it the meter reads 40mA after plugging it into the AC adapter, then reads 100-120mA after plugging it into the phone. But the phone doesn’t show the little lightning bolt.

There’s 3 smaller cables inside the lighning cables so would it be (+), then some data in the middle, then (-)?
