Réponse à : « My iPhone will not turn on after several hours of charging. HELP? »Nooooo wayyyy whoever said the hairdryer thing is so smart it actually works i did it for like 30 seconds and turned it over and it turned on. It makes sense tho heat creates resistance, and potential difference (voltage) is the force of how hard the currents are pushed. If the AC current supplied by the mains stays the same then because of Voltage = current x resistance, keeping the current the same, while increasing the current will increase the potential difference and it will push current into your battery. It’s not even deep think about accidentally leaving your phone on the radiator for 30 seconds it’s not gonna blow up.
