My IPhone charges 0-100% in 4 hours The current temperature is 4 degrees here But when I make my iPhone a little hot it charges fast Should I try once blow dryer to fix or what??

Shahid Akbar, it’s normal chemical reaction of the battery in -4C to 5 C. nothing to be worried about. :-) basic physics

Hi

  • are you charging via computer or via wall socket?
  • are you using the standard official charger that ships with the iPhone? An Apple lithium-ion battery uses fast charging to quickly reach 80% of its capacity, then switches to slower trickle charging. So typically, a 0%-100% should take you around 3 hours, give or take. Some tips to achieve faster charging:
  • Use a wall socket
  • Use an iPad charger (It’s rated at higher amperage)
  • Switch on Airplane mode while charging (charging time cuts down to almost half!) Hope it Works Thanks Varun
