The question is

  • What is the Health of the battery?
  • What were you doing on your iPhone?
  • Was it connected to counterfeit charging cable?
  • Did your iPhone had protective cover which does not provide good ventilation?


Lastly, purchase Apple Products, from an Apple Online Store, Apple Retail Stores, and many Apple-authorized resellers and wireless service providers.


Secondly, It is not clear here in your post about the ambient temperature in your area where you are using the iPhone. However --> Keeping iPhone, iPad, and iPod touch within acceptable ...


Store the device where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leave the device in your car, because temperatures in parked cars can exceed this range.


Use iOS devices where the ambient temperature is between 0º and 35º C (32º to 95º F). Low- or high-temperature conditions might cause the device to change its behavior to regulate its temperature. Using an iOS device in very cold conditions outside of its operating range might temporarily shorten battery life and could cause the device to turn off. Battery life will return to normal when you bring the device back to higher ambient temperatures. Using an iOS device in very hot conditions can permanently shorten battery life.

Before updating to the latest iOS 14.1 as told on your post what was your earlier iOS version. Then you can look into the iOS changes that has happened between the earlier version on your iPhone and this new version that you have updated now. 


This will give you a broader idea of the issue, if it is directly linked to the iOS version or is triggered by something else.

Me too. I’m a diehard 6S user that has kept phone up to date and have had NO issues with it ... until it updated to 14. Literally overnight I went from a perfectly usable phone that would last me all day on a single overnight charge to one that is basically dead by lunch - with minimal usage! The phone gets hot to the touch while simply using it for normal things for anything longer than a few seconds.


According to the phone, Battery Health is great, as I would expect since there was literally never an issue UNTIL this update. 14.2 did not fix any of the issues.


As I sit here typing this and looking at my stats, my phone was last charged to 100% an hour ago (it’s now at 48%). Last week, I averaged 2 hours 45 minutes of On Screen time with about 10 hours of off screen time - all while using about 260% of battery. (That means I had to charge it at least twice each day, after a full charge every night).


This ‘update’ has been nothing but problems. I’ve had iPhones ever since they came out, but now I’m looking at switching to Android for the first time ever. My phone is unusable as it is. And no. Upgrading to a new phone is not going to fix and iOS problem.

I have the same problem. One week EXACTLY after getting the 14.2 update, my phone started overheating, the battery drains 1-2 % every minute or so, and I can barely use it. Forget making phone calls, which I do for a living, because it will overheat and shut down. It also starts making these strange squealing noises and beeps. My LIVELIHOOD depends on my phone working!!! I need this fixed ASAP! I am VERY upset about this.
