> My laptop's charger causes my phone to overheat. The charger which came with your phone probably doesn't output enough power to charge your phone at its maximum speed, while your laptop's charger has more than enough power for that. But what decides at which speeds to charge is actually your phone's built-in charger (what we are calling a "charger" is actually a power supply, the true charging circuit is always within the phone itself). So if your phone is overheating, either it's just hotter than you expected but still within its design parameters, or your phone charging circuit was badly designed. > When I plug my laptop in to my phone's rapid-charger, it sometimes trickle-charges and sometimes does nothing. Even funnier than that: when I plug my phone into my laptop using a USB-C to USB-C cable (because the phone's battery is low and the power is out), the phone tries to charge the laptop; I have to go to the USB control in the phone's notification area and tell it to do the opposite.
