Apple says older devices slow down due to batteries not iOS updates (yeah OK)

It is a generic android message when you use a lower amperage charger or thinner gauge USB cord that doesn't allow the phone to pull its maximum amperage draw. My Moto e4 doesn't give me that message with a "normal" gauge aftermarket micro-USB cable or aftermarket charger with an output of 1A or more (the factory charger that came with mine is 2A, but some e4s ship with a 1A charger), but does give the message with a retractable micro-USB cable (much thinner wire) or a aftermarket charger with an output of less than 1A, my old LG Optimus Zone 2 did the same (though it came with a 0.85A charger so it only displayed the message on 500mA [0.5A] or less aftermarket chargers).

It could also be the Qualcomm fast charging... The fast charging for my Moto G is 12v. I plugged it into the USB analyzer i had. Had being the keyword. USB analyzers don't like 12v.

I'm hoping that it's just the charger being a cheapo. The USB charger that's in my father's 2012 Jeep Liberty, looks like a POS...

One of the workers, with the black Kia Soul, literally the most gutless motor of any vehicle I have been in during the late-2010s, IIRC, betrayed me. (On January 22, IIRC) Thought that it was cool to create a conspiracy to file a false police report, to have my sister arrested and jailed for assault & battery! Shit!

The jerk stole my USB cord... But found another one that seems to be fitting well...

There's also the apparently patented 9V+ charging system that newer phones will complain about not having if you just hook up a regular 5V charger (it needs to negotiate with the charger to 9V else that charger could destroy other devices). Still wondering about reverse engineering one somehow, and whether these chargers work properly with 5V 2A charging that simply short D+/D- ...

Who the heck did that??? Did some folks not learn from the dreaded flip-phone era??? Back when a Motorola would literally yell "unauthorized charger" on the screen... (one of their flip phones, IIRC)

Don't know, I didn't find the patent or if there is one, but I'm sure there is... Qualcomm probably owns the patent and apparently multiple people licensed it by buying their charge controller chips (like my Asus...)

It won't say "Unauthorized Charger" but will say "Slow charge" or something like that so people know why it doesn't charge as fast as the original.

Ahh looks like the protocol to trigger the charger to dump 9-12V is documented. Now I can make my own charger for my Asus... or at least I should be able to...

Some example of fast charging.
