A simple fix and no panic will fix iOS 16.5 Battery Drain and OverHeat Issues


Share post:

It is pretty common that with every major software version rollout, some sections of users face issues. This time it is iOS 16.5 battery drain and overheating issues reported after its release on 18th May. On the contrary, it is expected that will a new iOS update rollout, battery life will improve.

However, it is worth noting that software updates, including iOS updates, are typically aimed at improving device performance, fixing bugs, and introducing new features. While it is possible that some users may experience issues or perceive changes in battery life after an update, it does not necessarily mean that every user will encounter the same problem.

Battery life can be affected by various factors, including usage patterns, app behavior, and device settings. It is always a good practice to follow some general tips to optimize battery life, such as managing background app activity, adjusting screen brightness, and updating apps.

What is iOS 16.5 battery drain issue?

Multiple iPhone users have recently reported a concerning issue with iOS 16.5, stating that it has significantly impacted their devices’ battery performance. The Mirror has cited complaints on social media about the update “absolutely decimating the battery on my iPhone 12 Pro” devices, with claims that the battery drainage is even worse with iOS 16.5.

A quick search on Twitter reveals users asking Apple support about an update or fix for iOS 16.5’s battery drain, as well as individuals expressing concerns about their battery life, slow charging, and unusually hot temperatures since the update.

Rumor doing rounds says that new iOS updates tend to drain an iPhone’s battery life, especially for the older models forcing users to buy newer Apple products. However, this is not the case.

The phenomenon where iPhone batteries often experience drainage after a significant iOS update is true some users have reported this issue in the past. After major iOS updates, it is not uncommon for the device to go through background processes like app indexing, optimization, and other system tasks that can temporarily impact battery life.

During these initial stages, the device may consume more power than usual as it adjusts and optimizes its software and settings. This behavior is generally considered normal and expected after a major update, and it typically stabilizes within a few days as the background processes are complete.

To mitigate the impact of battery drain after an iOS update, it’s recommended to keep your device connected to a power source during the initial stages, allow it to complete its background tasks, and follow general battery optimization tips such as reducing screen brightness, disabling unnecessary background app refresh, and managing location services.

However, it’s important to note that individual experiences may vary, and not all users may experience significant battery drain after an iOS update. Additionally, Apple continually works to improve battery efficiency with each update, so it’s possible that subsequent updates may address any battery-related issues that arise.

How should you fix iOS 16.5 Battery Drain issue?

Apple is aware of the glitch, provided they considered it one, but the behavior is completely normal with the below explanation.

After a major operating systems update, such as iOS, the device often undergoes various background operations, optimizations, and data scanning processes. These activities, including the re-scanning of photos using new machine learning algorithms, can indeed lead to increased battery drain in the initial period following the update.

Battery management on modern devices is typically handled by sophisticated algorithms that adapt and optimize battery usage based on usage patterns and user behavior. These algorithms may require several charge-and-drain cycles to calibrate and adjust their settings for optimal battery performance.

During this calibration phase, it is normal to observe fluctuations in battery life and potentially higher power consumption. However, as the algorithms gather data and learn from usage patterns, they aim to improve battery efficiency over time.

To assist the battery management algorithms during this adaptation period, it’s recommended to use the device normally and allow it to go through regular charging and discharging cycles. This helps the algorithms gather accurate data and optimize battery performance based on your specific usage patterns.

It’s important to note that while these initial adjustments may cause temporary battery drain, the overall goal of these background operations is to improve the device’s performance, enhance features, and optimize battery life in the long run.

This has happened in previous major OS rollouts and Apple has responded that it is normal

It is indeed frustrating to experience battery drain after an iOS update, and it’s natural to worry about potential permanent effects on the device. However, it’s important to note that the temporary battery drain phenomenon following an update is typically a result of background processes and optimizations.

The good news is that this iOS 16.5 battery drain is generally not indicative of any permanent damage or long-term impact on the device or its battery. It is a temporary adjustment period during which the operating system and associated algorithms optimize performance, settings, and battery usage.

The device will typically stabilize its battery performance within a few days as these background operations complete and the battery management algorithms adapt to your specific usage patterns. Once this calibration phase is over, your device should return to its normal battery life.

If you notice that the battery drain continues beyond a reasonable adaptation period or encounter any persistent issues, it’s advisable to reach out to Apple Support for further assistance. They can provide specific guidance and help troubleshoot any potential underlying issues.

Rest assured that the temporary battery drain experienced after iOS 16.5 update is a normal part of the optimization process and does not indicate permanent damage or long-lasting effects on your device.

Stay tuned to Apple’s official announcements and updates for the latest information on iOS 17. The Worldwide Developers Conference (WWDC) is an event where Apple often reveals its upcoming software updates, including iOS. The specific details, features, and release date of iOS 17 will be officially announced by Apple during the event. It’s a good idea to follow Apple’s official communication channels, such as its website or social media accounts, to stay informed about the latest developments and announcements regarding iOS 17.
