Battery performance can be vital to the lifespan of a cell phone.
Since iOS 11, Apple has made battery information available in iOS settings in order to be more transparent; about the health of the component and how this can influence the performance of the device; See how to check battery health on iPhone in this article and find out what's really happening to your device's battery.
The estimated capacity of the battery explains whether it can reach peak performance, in addition to the operating system itself; now informs the user if their device is being harmed due to a degraded battery.

What happens is that performance management anticipates problems related to degradation; of the power component, especially when the operating system has an unexpected shutdown.
Other factors can also affect battery performance, such as new features that come with the system; new updates, constant use of location tools (GPS), installation of beta software, among others.

Furthermore, iOS is also smarter when it comes to flow control when the device is on the charger. The optimized charging feature allows it to learn your iPhone charging and usage routine, preventing battery drain.
Important: if you are an iPhone 11, 11 Pro or 11 Pro Max user, you may need to recalibrate; to resolve unexpected discharging errors, reduced performance and correct the exact battery percentage.
Check out, in this article, how to check the health of your iPhone battery, how to disable the management function; performance and how to manage the use of the power component in the device.
How to Check Battery Health on iPhone
To find the section that provides information about your iPhone's battery health, go to the app “Settings” > “General” > “Battery” > “Battery Health”. On this screen, the Maximum Capacity reading provides an estimate of the total productivity that the battery can support (i.e., its useful life).
If the device is new, it should show that the device has 100% capacity, or something very close to that.
A lower capacity value means that the battery will not hold a full charge for the same amount of time as before.
Below, there is the section titled “Maximum Performance Capacity”, which indicates whether the battery is allowing iOS to deliver; maximum performance, or if battery degradation is compromising this task.
In this case, with the battery degraded, the iPhone will activate the performance management functionality, which reduces the device's capacity and prevents unexpected shutdowns.
iPhone 11, 11 Pro and 11 Pro Max users will see a message about component recalibration in this section. The process is automatic and may take a few weeks to complete.
If successful, the warning will be removed and both performance and capacity percentage will be normalized.
Disabling performance management
If your iPhone has turned off unexpectedly, iOS will display a message saying something like “this iPhone has suffered; an unexpected shutdown because the battery was unable to provide the maximum capacity required.”
Therefore performance management was activated to prevent this from happening again.” This feature dynamically slows down the processor to reduce demands on maximum battery capacity.
In fact, you can also simply disable the power reduction, which is a new option offered by iOS.
To deactivate, go to the section “Battery Health”, tap the button to “Disable”, which appears at the end of the message; in the field Maximum Performance Capability (it should be highlighted in blue so it's easy to recognize).
After this option is chosen, the following message will be displayed: “This iPhone experienced an unexpected shutdown because the battery was unable to provide the maximum capacity required. You have manually disabled performance management protections.”
However, it is worth noting that, once disabled, performance management cannot be reactivated. This means that the device will not suffer a decrease in power until the next time the device is turned off; as the battery will not be able to provide sufficient maximum capacity.
Therefore, the iPhone will still automatically activate performance management when an unexpected shutdown occurs; that is, if you do not want to experience a decrease in the power of the device; You will need to go to the “Battery Health” section again and repeat the entire process after this event.
Therefore if it is not in your interest for the device to be slowed down, it is recommended to obtain a physical battery replacement. To do this, we recommend that you contact Apple Technical Support to schedule a repair service.
However, it is highly recommended to seek the official services of the Apple company and avoid third parties that offer to exchange this component.
See how to check the battery health is genuine, on iPhone XS, XS Max, XR and later, non-genuine batteries; that are installed on the device will not have any warning about the health of the component.
In fact, this Apple condition aims to protect the user, avoiding possible accidents that put their physical integrity and that of the device at risk.
Managing battery usage
To check which apps are using the most energy or if you think the system itself is the villain, go to “Settings”> “General”> “Battery“.View the full 24-hour usage report for the last 4 days.
Therefore See also when it loaded up to 100% and below is the list of apps that are consuming the most charge and activity on your device.
It's important to check this list if an app is consuming more battery than it should
However, still in the section "Battery", you can enable the “Low Power Mode” whenever you want to have more time to charge your device.
Finally, the feature temporarily slows down background activities until the iPhone is fully charged.
