Many Apple users will find that their phone speed begins to slow down after using the iPhone for a year or two. Apple recently admitted that this is out of the thought of enhence user experience. Under certain conditions, limiting the peak processor performance of some older models can reduce energy consumption, the purpose is to avoid the external battery charger from running out of power and automatically shutdown. Apple therefore becomes the target of public criticism.
The external battery charger Gate starts from Dec. 10 when an user in Reddit share on Facebook that after he automatically replaced his iphone 6S battery, the phone processing performance rises about 70%. Then on Dec. 18 John Poole, the founder of Geekbench shared the test statistics on Twitter to prove the user’s experiment. And now the United States Apple user mass litigation continued.
From Apple's response, it means that older iPhones would try to take in energy beyond the bear range of the batteries, causing a sudden shutdown. In order to prevent this from happening, Apple is controlling the amount of power these phone models can absorb. In short, the old external battery charger will not provide enough power for the new version Iphone.
In order to avoid the phone from automatically shut down, Apple add this to the system. When the processor requires high performance, the request would be split into multiple lower-performance requests to prevent automatic shutdown problem due to external battery charger aging.
In other words, the current system would automatically check the external battery charger aging situation and limits processor performance based on this situation. This is also the reason why some users find the phone runs faster after replace their battery.
Some foreign media said that in the face of external battery charger aging problem, Apple should replace the battery for the user, rather than reduce the phone performance.
