iPhone users face battery draining issues after iOS 17 update, Know why

Recently, Apple rolled out its highly anticipated iOS 17 update this week, bringing a host of new features for compatible iPhones. These include improvements on calling, messaging, FaceTime, AirDrop, and other features, while maintaining the familiar user interface.

However, just within a week after the release of iOS 17, there has been a buzz among iPhone users about battery performance concerns. This has been coming especially from people with older devices.

Major OS upgrades often demand more processing power and storage, which can affect battery life. Complaints have flooded the Apple support page regarding reduced battery life with iOS 17 update, suggesting that a new iOS 17.1 version might be in the works to address this issue.

One user expressed frustration saying, “My iPhone 14 battery life just randomly went from being great to draining like crazy.” Another user humorously commented, “My iPhone battery is as low as my will to live,” highlighting the annoyance. A third user questioned Apple, “How does it drop 10 percent in 10 minutes with no usage?”

So, what’s causing this problem? Tech YouTuber Marques Brownlee, also known as ‘mkbhd,’ provided insights on this in an Instagram reel. He explained that batteries naturally degrade over time, resulting in reduced capacity. To prevent iPhones from suddenly shutting down due to this degradation, Apple has under-locked the CPU frequency.

If users encounter battery issued, they have to option to activate the ‘Peak Performance Capability’ option, which manages performance to match the battery’s capabilities. iOS now dynamically controls the maximum performance of the CUP, GPU, and other components to prevent excessive power consumption, reducing the chances of unexpected shutdowns. However, this may lead to slightly slower performance in some situations.
