What is Battery and Heating issue in iOS 16.5?

The battery draining issue was present in iOS 16.4 as well, and many were expecting Apple to fix it in the next update. However, the new update did more bad than good for most users. There were complaints about the iPhones heating up and draining the batteries faster than usual.

Apple forums are lined with users' grievances like losing significant battery charge overnight and even while using the phone. The problem persists even in brand-new iPhones with good battery health, updated to iOS 16.5.

What's more alarming is that despite taking measures like turning off background refresh, lowering screen brightness, turning off the 5G network, etc., the issue persists for many iPhone users. It is especially concerning if the iPhone is your daily driver.

Can you roll back from iOS 16.5 on your iPhone?

Apple recently announced that 81% of iPhone users are on iOS 16. The Cupertino-based tech giant is known for phasing out older versions of iOS after a new update arrives to encourage users to stay on the latest software. Conversely, the company stops signing previous versions to stop users from downgrading.

After the launch of iOS 16.5 on May 18, Apple stopped signing the iOS 16.4.1 update, the previously available version. As a result, it is currently impossible to downgrade or roll back on your iPhone. If you have already updated to iOS 16.5, wait for iOS 17 on your iPhone and hope Apple fixes the overheating and battery-draining issues.
