Quick Charge. People want their phones to top up from dead in less than an hour. Forcing that much current into a lithium-ion battery isn't a good idea.
The solution? Make them take longer to charge. Puts less stress on a battery that's made out of volatile materials. Stop trying to appease impatient braindead idiots that want a design feature that's inherently incompatible with safety w.r.t. current manufacturing materials for batteries.
It's been known for several decades now that charging a lithium-ion cell too quickly = ALLAHU AKBAR!, yet people still want it, why? Because they choose to smoke weed and get pregnant instead of paying attention in high school chemistry class, and grow up to be fucking idiots.
...is xhtml.weather.com. A long time ago I had a 30MB data plan and this was one of a few websites that continued to work after running out of data and getting paywalled, although most of the graphical assets were stored on a different domain and thus didn't load post-data bucket depletion. m.us.yahoo.com also used to work, but that was plugged in 2014.
TCP port 53 used to also be wide open, but from what I gathered on various forums, that was patched during the last major VoLTE outage. Two other users commented elsewhere on this story that this port (and it's UDP counterpart) as apparently still open on Verizon Wireless. However, I'm unable to confirm this paragraph.
No amount of genius can overcome a preoccupation with detail.
