How to check battery status and manage the performance of the iPhone on iOS 11.3
iOS 11.3 has added the wait function that allows you to check the battery status and whether or not the decrease in performance when the same battery is going to deteriorate on the iPhone. Here's how these two innovations.
iOS 11.3 should be to improve the function of performance management through a periodic evaluation is necessary to avoid shutdowns unexpected. If the state of the battery can support the power requirements for the peak power recorded, the level of performance management is reduced. If it occurs again, shut down unexpected, the management of performance is increased. This assessment is continuous and enables a performance management more adaptive.
On iPhone 6 and later models, with iOS 11.3 is then to add new features and to view the status of your battery and advise whether there is a need to replace it. These functions are available on Settings > Battery > Battery Status (now in beta).
Thanks to this option, users can verify the function of performance management, which manages dynamically the maximum performance in order to avoid shutdowns unexpected, both the active and can choose to turn it off. This function is active only after the first event of unexpected shutdown on a device whose battery has a smaller capacity of the maximum power the snapshot. This function is available on iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone IF iPhone 7 and iPhone 7 Plus. Apple know that iPhone 8, iPhone 8 Plus, and iPhone X are not affected by this decrease in performance.
Apple does know that if the need for a performance management more effective, the user may notice effects such as:
There are also many important aspects that do not suffer from the effects of the function of performance management. Among these:
All models of the iPhone, instead, include a basic management of performance to ensure that the battery and all the system are working as expected and that the internal components are protected. This management includes the behavior at hot temperatures or cold, and the management of the internal supply voltage. This type of performance management is mandatory for safety and to monitor the expected behavior and cannot be disabled.
The new Battery Status screen displays information on the maximum capacity of the battery and the maximum performance capacity.
The maximum capacity of the battery measures the battery capacity of the iPhone when it was new. At the first activation, the batteries have a capacity equal to 100%. With the ageing of the chemical, the batteries will begin to have less capacity, resulting in a lower number of hours of use between recharges.
A common battery is designed to retain up to 80% of original capacity after 500 cycles of complete charge and discharge, operating in normal conditions. The one-year warranty includes service coverage in the event of a defective battery. If it is out of warranty, Apple offers assistance for the battery for a fee (29€ until 31 December 2018).
If we see a deterioration of the status of the battery, then you will also have a reduction of maximum performance capacity (on iPhone 6/6 Plus, iPhone 6s/6s Plus and iPhone 7/7 Plus).
The Battery Status screen includes the item's maximum Capacity performance in which the following messages are displayed:
The performance are normal
This message appears when the condition of the battery can support the maximum performance and functions of performance management are not active. The complete message shown by iOS 11.3 and later is your battery currently offers peak performance standard.
Performance management capabilities-from active
If you have activated the functions of performance management, and when the battery starts to deteriorate, instead, you receive the following message: You experienced the sudden shutdown of iPhone because the battery has not been able to ensure that the peak power required. To prevent the problem from occurring again, it has implemented a performance management system.
Caution: as explained by Apple, if you disable the management of performance, you will not be able to re-activate it. In the case of a new unexpected shutdown, this will be reactivated automatically. You will also have the option to disable it.
Battery status unknown
S iOS is not able to determine the status of the battery of the device, the following message is displayed: your iPhone is not able to determine the status of the battery. Please contact an authorized Apple assistance. More info about the options of care...
This error may be caused by the incorrect installation of the battery or the non-recognition of a battery.
Performance management off
If the user disables the function of performance management is applied, the following message is displayed: There was the sudden shutdown of iPhone because the battery has not been able to ensure that the peak power required. You have manually disabled the security options of the performance management.
If the device turns off again unexpectedly, the functions of performance management will be applied again. You will also have the option to disable it.
Battery status has deteriorated
Finally, if the state of the battery has suffered a significant deterioration, you also receive the following message: The performance of your battery are decreased significantly. By paying a visit to an Apple authorized service provider, you can replace the battery in such a way as to maximise again the autonomy and the performance. More info about the options of care...
This message does not indicate a security problem. The battery can still be used. However, it is possible that the battery and performance highlighting other significant problems. In this chaos, it is recommended that you replace the battery.
