As we have shown here on the site, the iOS 13 It now uses machine learning to optimize the recharging of iPhones batteries and thus extend their life. This applies to all generations compatible with the new system, but the new hardware brings something more.
Apple itself noted in a new supporting article that iPhones 11, 11 Pro and 11 Pro Max They feature special hardware to minimize performance degradation with degraded batteries. How this works in practice, however, is a mystery.
The fact that the battery consumption of these devices is now constantly monitored, so the operating system can intelligently direct hardware resources and avoid waste.
Still, there is no miracle: after a certain time (1-2 years or more, depending on the intensity of use) and / or the number of cycles on the battery, that health percentage will drop and, gradually, the device performance will be affected until you replace the battery with a new one, that is.
XS, XS Max and XR iPhones being limited
Beginning with iOS 13.1, which will be released tomorrow, the XS, XS Max and XR iPhones will be placed on the list of devices that may have limited performance if a degraded battery is identified by operating system monitoring.
The move, as Apple explained at the time of that massive battery policy, is to prevent the iPhone from crashing or restarting unexpectedly due to some performance spike that its battery could not handle.
Remember that this feature only comes on after the first time the device goes through an incident due to its degraded battery, usually with 80% health or less, and can be disabled if the user prefers it.
