This is how Apple slows down the iPhone with degraded batteries


The batterygate is already a scandal of Herculean proportions that every day that goes by brings with it a new multi-million dollar claim to the firm based in Cupertino. Although it all started as a reddit thread published by a 17-year-old kid , Apple confirmed it days later and after the avalanche of complaints and denunciations, it has now promised a new more transparent policy and replacement prices for "popular" batteries : of 89 at 29 euros.
And is that your iPhone is slower can be solved simply by replacing the battery . But first of all, let's get into the background. This is Apple's explanation of the matter:
"This energy management works by combining the temperature of the device, the level of charge of the battery and the impudence of the battery. Only if one of those variables requires it, iOS will dynamically manage the maximum performance of some system components such as the CPU or the GPU to avoid unexpected blackouts.
As a result, the process loads of the devices will be adjusted, allowing a more optimal distribution of tasks, avoiding peak performance. In some cases users may not notice differences in the performance of their terminal in their day to day. The level of perceived change depends on how much energy management is necessary. "
So that we understand: that the iPhone with old batteries can not provide enough power to operate at full capacity without damaging the iPhone's components. So when an iPhone notices that there is not enough voltage, something that could be potentially harmful, it would automatically shut down .
This happens because Apple has programmed software that prevents this damage and blackouts by managing the performance of the components through a dynamic adjustment, so that these blackouts do not occur. We insist, this is a preventive security feature of Apple, not a bug .
How does the user notice it?
Apple says that in some cases we might not realize it but the reality is that the user experience is certainly affected . According to the Apple document, a lower performance of its components translates into:
  • It takes more time to launch an app .
  • Lower screen refresh rates when scrolling
  • Darkening of the backlight (which can be bypassed in the Control Center)
  • Lower speaker volume up to 3 decibels
  • Gradual reductions in frame rates in some applications
  • In extreme cases, deactivating the camera's flash
  • Apps that are open in the background will also require more time to launch them again

What things will continue to work like the first day?

Apple has advocated transparency after the scandal, so in addition to explaining what is affected and how this software function works, also wanted to detail what functions of the iPhone are not affected :
  • Quality of calls
  • Connectivity performance
  • Quality of photo and video
  • GPS performance
  • Accuracy of the location
  • Sensors such as gyroscope, accelerometer, barometer
  • Apple Pay
