At the end of last year, users discovered that an iOS update was causing their old iPhone to slow down. It turned out to be an intentional iOS feature, while Apple was trying to prevent older iPhones from stopping unexpectedly under heavy load. It turned out that limiting processor speed would prevent downtime.
In the months following this discovery, Apple apologized to users, set up a cheaper battery replacement program for the iPhone and disputed claims that such features are part of the iPhone. an obsolete strategy to convince buyers to switch to the newer iPhone. Apple even had to answer congressional questions about it, explaining how the regulation of its processor works.
In a letter to legislators, Apple explicitly said that newer devices, such as the iPhone X, iPhone 8 and iPhone 8 Plus, would not be affected by slowdowns in the future. But it turns out that this is not really the case.
This is how Apple explained the problem in Congress in early February:
The iPhone 8, iPhone 8 Plus and iPhone X models use a more advanced hardware and software design that provides a more accurate estimate of power requirements and battery capacity to optimize overall system performance. This allows a different performance management system that specifically allows iOS to anticipate and avoid an unexpected shutdown. As a result, the effects of performance management may be less noticeable on iPhone 8, iPhone 8 Plus and iPhone X. Over time, the rechargeable batteries of all iPhone models will decrease in capacity and peak performance and may need to be replaced. .
Go quickly to iOS 12.1, which has just appeared, and you will find that Apple has quietly updated its battery support page and iPhone performance to include the iPhone 2017 in the list, as observed for the first time by The edge – our accentuation:
In addition, users can see if the performance management feature that dynamically handles maximum performance to avoid unexpected shutdowns is enabled and can choose to turn it off. This feature is enabled only after an unexpected shutdown occurs for the first time on a device with a battery having a reduced capacity to provide maximum instantaneous power. This feature applies to iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7 and iPhone 7 Plus. Starting with iOS 12.1, iPhone 8, iPhone 8 Plus and iPhone X include this feature, but performance management may be less visible due to their more advanced hardware and software design.
This does not necessarily mean that if you bought an iPhone 8 or an iPhone X at launch last year, you will soon experience a slowdown. But that could possibly happen, which probably explains why Apple has felt compelled to update the support page with the 2017 devices.
If this happens, at least you will know that your battery has aged enough to no longer allow the iPhone to run at full speed. A battery change will restore performance. To learn more about the health of your battery, go to settings app and then Drums, so what Battery status. This is where the state of battery degradation is and if it still supports maximum performance.
