Apple saw fit to release iOS 14.6 a week or so ago and it harms the battery life of new and older iPhone models. To be fair, the past few point updates of iOS 14 had a negative impact on the battery of most iPhone models. Many users have reported excessive drain with overheating issues on their devices. A new video has emerged that aims to show iOS 14.6 in a battery drain test to corroborate the theory.

The video is shared by the YouTube channel iAppleBytes that compares iOS 14.6 battery drain test against older updates. Apple did not include any battery-related fixes in the changelog, so it would be interesting to see how the latest build stacks up against older updates. In my view, iOS 14.6 did take a hit on my iPhone 12 Pro Max. I have noticed a sudden decline in percentage over minimal use. In one instance, even Instagram scrolling chopped about 10 percent in 15 minutes. In addition, the e=device got a lot hotter near the camera module.
