One of the most common issues that users are experiencing is battery drain. If your iPhone’s battery drains faster than usual after installing iOS 16, don’t worry– you’re not alone. This article will show how to fix the iOS 16 battery drain issue.

Users with iOS 16 installed on their iPhones are experiencing quick battery drain issues. They are complaining on Reddit, Twitter, and Apple forums.

Latest Update:

  • Several iPhone users running iOS 16.1 are reporting the battery draining issue.

I wonder why I am facing battery drain issues after updating to iOS 16.1, especially with iPhone 13 series.

I just updated my iPhone 13 pro max to ios 16.1, and then suddenly, the battery consumption is draining faster even though I already charged.

I purchased iPhone 12 on April 24, 2022, and it’s not even six months, and I have lost 5% battery health after I updated to iOS 16.1. I lost 1% of battery health every week. One user replied, “Same here, I lost 5% of my battery health”.

  • As per some users, the iOS 16.0.3 update has fixed the quick battery drain.

Honestly, since I updated to iOS 16.0.3, the battery life on my iPhone 14 pro max has slightly improved. Hopefully, when 16.1 comes out, it can get better.

The battery has definitely gotten better on 16.0.3. Can’t wait to see if 16.1 will make it even better.
