Re: Statistically speaking
Li-ions, and Li-Pos, and bears, OH MY! My kid sat on an iPhone 6+, bent it good at the volume control area, and it worked fine for weeks. Not a crack in the screen, not a peep from the device. Replaced it with a new iP7+ flat black. No defects in the paint, no problem with the battery, of course. They are supposed to be pulling 1A, and ship with the customary 1A mini charge plug, but I've been monitoring all my iDevices and they will pull up to 1.5A or slightly more for the iPad Pro 9.7" during the deeper charge cycle, then taper off as they near the 100% level. Kids, Li-ion batteries can blow up if damaged or manufactured below specs. And two phones out of dozens and dozens of millions of phones is hardly a panic. More likely it was sat on and/or charged from damaged or non-Apple charger.
And don't rule out the cable, boys and girls. I went through and tested every one of my charging cables, and the pretty colored & coily ones turned out to be total crap, as were some non-branded ones, and the Air Hogs microUSB charging cables (but they are only for low-amp droney-copters that are pulling less than 300mA. so, no fear). The Apple, Samsung, vaporizer, and other cables could deliver well over 1A. Get a USB power checker, you guys! It's a must if you have, you know, devices and stuff.
Still, this is a little bit of good news for the two people who bought Windows Phones and are still pissed about it. :P
Which reminds me; I must test the output of the so-called 2A Samsung chargers and the 1A Apple ones. So far, I've only been testing with a 65W Siig 5 port charger (the golden boy!) and portable chargers. I needed to test every cable so my Raspberry Pi devices would not complain about the lack of power. Damn crappy cables!
