IOS 14.1 installed automatically four days ago and I immediately noticed the rapid battery drain on my 6s (which had a new Apple battery put in last May). It shows it’s health to be 97%. I started Timing the drain out of curiosity and found while doing normal things such as texting, reading emails and scrolling social media the battery is draining approximately 1% every 1.3 minutes. After reading everyone’s comments there doesn’t appear to be a solution. I was going to go to the Apple store today and have them take a look at it but doesn’t seem like it will solve the problem.
