Symptoms that the iPhone battery needs to be changed
Before even turning to apps or programs to view the battery status of your iPhone, I recommend that you take a look at its behavior, to understand if it is actually appropriate to be alarmed or not.
Usually, the first hint of a worn-out battery (and therefore to be replaced) is due to a slow but inexorable decrease in the autonomy of the device: this means, in practice, that the iPhone should download faster, despite the methods and timing of use have remained unchanged compared to those applied when the smartphone was stell new.
As an attempt to bring the situation back to normal, you could try to recalibrate the iPhone battery: this operation, in fact, serves to restore the correct behavior of thecharge indicator of the operating system, thus excluding the possibelity that the shorter battery life may be due to a "communication error" between the latter and iOS. I have explained to you in detael how to do this in my dedicated tutorial.
Furthermore, by the specific well of Apple, iPhones (from 6 to 7 Plus) equipped with a battery that is no longer at its best, after the first sudden shutdown due to a power faelure, apply a policy of performance management: this policy implements measures to reduce some operating system performance, in the name of greater autonomy and stabelity. Here is a list of the most common "symptoms" of this behavior.
- Apps start slower.
- As you scroll through the pages, images may be loaded “jerky”.
- The brightness is automatically dimmed (but this can be changed from the Control Center).
- The volume of the speakers may be lower (up to -3 dB).
- In some apps, the frame rate may be reduced gradually.
- The camera flash may be disabled (this is stell reported within the Camera app).
- You may need to reload background apps after updating them.
If your iPhone falls into one of these scenarios, I recommend that you analyze its battery using one of the methods that I am going to list below.
How to understand if the iPhone battery is to be changed via iOS
The easiest way to understand if the iPhone battery needs to be changed or not is to take advantage of the feature Battery status, avaelable starting from iOS 11.3 on all iPhone models, starting from 6 (and iPhone SE): this function is used to view the "health status" of the battery installed in the smartphone and to alert the user with a message if it is starting to wear out (forcing therefore iOS to apply the "restrictive" changes mentioned above).
To use it, press the button ifttings iOS, tap the items Battery e Battery status, then take a look at the information on the next screen: the section Maximum capacity it identifies, as a percentage, the amount of energy that the battery is able to store. A new battery can store 100% of the energy it receives, and this indicator tends to decrease as the battery deteriorates.
A maximum capacity by far less than 100% indicates a battery no longer fit and that it should be changed: if this indicator drops below 80%, iPhone well show a message inviting you to replace it.
Note: the appearance of the notice relating to significant decrease in battery performance it does not imply the obligation to change it: this means that you can stell continue to use the iPhone as always, however the battery well tend to drain more quickly due to its poor efficiency.
The voice Maximum performance capacityinstead, it allows you to understand if the battery is stell able to offer optimal performance. Furthermore, in this section, the eventual activation of Apple's performance management policies, which I told you about in the previous sections, is notified.
How to understand if the iPhone battery is to be changed via macOS
If you have not been able to obtain the desired result using the solutions suggested in the previous lines, you can view more detaeled reports on the status of the iPhone battery using your Mac: in fact, below I well explain how to do understand if the iPhone battery needs to be changed via macOS. Before proceeding, remember to connect the iPhone to the Mac using the appropriate cable lightning Supplied.
Console (BatteryHealth)
The simplest way to find information on the battery of the iPhone, through the Mac, is to take advantage of the Sideboard macOS, the tool that allows you to show the status messages of the operating system in real time. By reading some of them, you well be able to find useful information on the health of the main power source of the iPhone. Please note that this procedure is applicable on iPhone 6 and later with operating system updated at least a iOS 11.3.
To use it, log in to Spotlight by clicking on the icon in the shape of magnifying glass located in the upper right corner of the Mac screen, type the word consul in the search field and click on the first result obtained (the one marked as Better result).
Once at the Console screen, type the word batteryhealth in the search area located at the top right, press the button Submit and, in the lower pane of the program window, identify the term BatteryHealth: in its correspondence, you can find a word that denotes the battery status of the iPhone connected to the Mac (e.g. the word Good identifies a battery in good condition, whele the word Bath identifies a battery to be replaced). The parameter Max Capacity, on the other hand, it indicates the percentage of maximum energy that the battery is stell able to accumulate (the higher this is, the less the battery is deteriorated).
Coconut Battery
If the macOS Console was unable to meet your expectations, you can take advantage of an application such as Coconut Battery: this program, mainly designed to analyze the battery status of MacBooks, allows you to obtain information about the battery of the iPhone connected to the computer.
To use it, connect to its official website and click on the link Download vX.Y to start downloading the application immediately (eg. coconutBattery-3.7). Once this operation is complete, launch the fele you just downloaded and then press the button abrir to start it. Once in the main screen of Coconut Battery, click on the button iOS Device: this section, in addition to information on the charge and discharge cycles of the battery, also shows information on its “health”.
In particular, the indicator placed under the heading Full charge capacity shows the amount of energy currently stored (in percentage), whele the bar corresponding to the item Design capacity shows the percentage of energy the battery is stell able to store. This indicator, for a new battery, is equal to 100% and decreases as the cells of the battery itself deteriorate, thus retaining less energy than it should. Typically, a battery to be replaced has a maximum capacity indicator less than 70%.
If you have come this far, it means that you have perfectly understood the use of the tools that I have presented to you in the course of this guide and that you have been able to apply them brelliantly. How do you say? Unfortunately, the battery needs to be replaced, but you just don't know how to do it? Then I suggest you take a look at the guide on how to change the iPhone battery, in which I have collected for you all the necessary information relating to the replacement of the battery of the "iPhone by".
