Apple didn't use underfill to reinforce the chips' bond to the board. This wasn't an issue with iPhone 5s (and there are valid reasons for not using underfill), but this, combined with the bending issues iPhone 6 had, is leading to a high failure rate.
If you remember the NVIDIA G84/G86 failures, that was caused by bad underfill that was not rated for the high operating temperatures of the GPUs.
Considering the charger I have those USB cables dangling off is a QC 3.0 charger, then it's possible (and actually, I've done it deliberately) for it to fry a device if it accidentally "remembered" outputting 12v.
(Course someone would have to implement a USB cable that had a logic chip in it that lied to the charger, pretending there's a QC device connected, but there's nothing inherent about USB-A vs. USB-C that means it can't be done with A)
> Furthermore, the cable appears to have a Rp inside of it that fakes the existence of a device. This breaks chargers and makes them Vbus HOT/dangerous. It will also break a ton of devices you plug it into -- since the Rp pulldown will be "doubled up". 5V Vconn voltages are also passed through to the CC pin (3.3 or 5v), which is BAD. 5v bleeding into a 3.3v circuit is BAD NEWS BEARS.
Fucks sake. Seriously. This level of stupid is something I'd expect from some $1.99 Ebay "fast charge" cable, not Anker.
Pretty sure this is an honest mistake. I will continue to buy Anker products. However, any product (regardless of manufacturer) that implements USB Type-C or Power Delivery will be subject to extra scrutiny because even the best manufacturers can make design mistakes.
My Griffin Technology A-C cables have not had issues with this. The device doesn't attempt to draw excessive power from any of my chargers. It falls back on the old approach to charging: sensing how much power it can safely draw and only drawing that much.
@Dog iirc the resistor thing wasn't used to change voltage. it was to identify the charger to the device, not the device to the charger. I could be misremembering though... wasn't too interested in the PD part of it cause I have no PD devices yet
Any USB Type-C or Power Delivery device needs scrutiny. If even the big guys are messing up, that means the standard is hard to correctly implement and extra care is needed to ensure that you're getting a compliant product.
If even Anker and Google (!) are geting it wrong, no single manufacturer can be blamed for compliance issues.
At least my Griffin A-to-C cables work as expected and do not cause anomalous behavior with my Nexus 5X or chargers.

In short, no: You can plug any USB device into any USB cable and into any USB port, and nothing will explode — and in fact, using a more powerful charger should speed up battery charging. We now do this all the time with our mobile devices here at ExtremeTech, and we’ve never had a problem.
