I have the iphone 6s. After the update of 14.2 my battery would show fully charged. Within minutes of unplugging my phone from the charger and just reading my emails the battery would drop down to 60% within minutes. I’m saying to myself did my charger not work, so I go out and purchase a new charger. I go out of town that day and I’m using the waze app trying to find my destination. My phone with my new charger is plugged into my car cigarette lighter. When I get to one of my destinations after an hour and thirty minutes I unplug my phone instead of the battery charging the battery has decreased. I’m like how strange because this is a brand new charger. All of a sudden at 30% the phone just shuts off completely. Luckily I find an old charger in my car that I’m having to continue to plug in an out to get enough charge on the phone so it would come on. I’ve had to close all the open windows on my phone thinking this would help keep the battery charged. I’m deleting old pictures, decreasing screen sizes, lowering light content trying to get my phone battery life to stay charged longer than a few minutes. I refuse to purchase a new phone because the battery want stay charged due to a flaw caused by a software update.
