Use the Console app
information can be found in the standard Console program on your Mac.
Simply open the Console, connect your smartphone to your computer, and type in batteryhealth (iPhone must be unlocked).
This gives you more details about your device’s battery. E.g. current battery percentage, type of power source, etc.д.
But for most users, it’s enough that their battery health is just fine.
How to turn off the power management feature
See the blue word Disable at the end of the text? This is the only way to turn off the power management feature. By disabling the feature, you will see the following message:
That iPhone was suddenly shutting down because the battery wasn’t able to deliver the necessary peak performance. You have disabled power management.
Once you turn off the feature, you can’t turn it on yourself, but it will activate itself after your iPhone fails again and shuts down. Then you can turn it off again in the settings.
When to replace the battery in your iPhone
You can track your iPhone’s battery performance with the “Peak Performance” option. Here the iPhone will display various messages based on which you can determine if you need to replace the battery.
Apple has developed a useful option to keep you updated on the status of your battery. Here you can check if your battery is working properly. Here are some of the messages you may see:
- “Your battery is currently maintaining normal peak performance” if your battery has no failures and is working properly; you will see this message.
- “The built-in dynamic software and hardware will help counteract the decline in performance that can be seen as the iPhone’s battery chemically ages” this message may appear if you’ve had the iPhone for an extended period of time. This means that your phone’s battery has started to run out.
- “This iPhone has unexpectedly shut down because the battery has failed to deliver the necessary peak power. Performance management has been applied to prevent this from happening again”-this message means you have a battery problem. Along with the message, you will notice that your phone has slowed down.
- “The health of your battery has deteriorated significantly. An authorized Apple service provider can replace the battery to restore full performance and capacity”- If your iPhone battery capacity is below 80%, you will see this message. You can still use the same battery, but your phone will be much slower, so replacing the battery is recommended.
The last two messages indicate that you should replace the battery if you want the performance of your iPhone to be safe.
There are other things you should look at to determine if you may need to replace the battery:
- If your phone reboots and you see the message “This iPhone has unexpectedly shut down”. In this case, performance management settings will be enabled so that this doesn’t happen in the future. You can turn this off, but keep in mind that you cannot turn it back on. If another shutdown occurs, the option will be turned on automatically. In this case, you should consider replacing the battery.
- If you have a new iPhone but notice that it has slowed down, overheated, or failed to open some apps, you may need to replace the battery or take it to an Apple store to check.
How to check the battery wear and tear on your iPhone
To make your smartphone’s battery last longer, you need to follow simple recommendations that will significantly reduce wear and tear and extend its life. And there are two ways to find out how much of your iPhone’s old battery is being used wisely: using the iPhone’s standard tools, or using a computer program.
The standard means of the iPhone
There is a new feature in iOS 12, which is still being tested, that allows you to see the current status of the battery.
The iBackupBot is a special add-on for iTunes, which allows you to manage your iPhone files. Additional features of this tool include a section for viewing the iPhone’s battery status.
Please note that you must have iTunes installed on your computer in order for iBackupBot to work.
- CycleCount. This indicator means the number of complete charging cycles for the smartphone;
- DesignCapacity. Initial Battery Capacity;
- FullChargeCapacity. Actual battery capacity based on battery wear and tear.
Either of the two ways in this article will give you a comprehensive indication of your battery status.

Why does my 5s have no battery status line in the battery item ? Thanks.
My 4s shows actual capacity higher than the original, how come?? The battery was changed at an authorized service center.
Fedor, hello. There may be several reasons. First, the software may not display this data correctly. For example, just checked its work on the 5s and SE, it shows actual capacity of 100, which in principle cannot be. Also, it’s unclear how you got 158 full charge cycles on your replaced battery already. Or the replacement was done a long time ago? Secondly, your device does not have a system option to view the battery status, it appeared on the iPhone 6 and later models after updating to iOS 11.3 or later, therefore, since the system is not yet able to collect this data properly, you should certainly not expect it from a third-party program.
Why does it say 100 on the 5s??! Is this a bug in the program or is it actually so?
Hello. Because, as it is written in the comment under which you left your question, the program may not display this data correctly. The battery status of 100 on the iPhone 5S can only be the only case after its replacement with the new original battery. But in the case of this model, you can only trust the information about the maximum capacity, which is displayed in the settings of the operating system, not in third-party programs.
On the iMac
When you upgrade your computer to MacOS Big Sur, you’ll see that the “Power Saving” section is no longer in System Preferences. The “Battery” section appeared in its place. It’s not hard to guess where it leads.
Click on the icon, and you will see a picture that you may have already seen on your iPhone. Get an idea of how much you’ve used your battery in the past 24 hours or 10 days, and get access to all your previous power-saving settings, including the scheduled startup and shutdown times for your Mac.
Unfortunately, as with the iPad, you won’t be able to see the overall condition of your battery. You can get an idea of how many charge cycles your battery has gone through by clicking “System Information” and then going to the “Power” tab under “Hardware”.
There you will see the number of battery cycles, information about its condition and maximum capacity, and can compare the number of cycles with Apple’s limits.
How to maximize iPhone battery life: a guide
How To Check Battery Health On iPhone 13 mini/iPhone 13/iPhone 13 Pro/iPhone 13 Pro Max (iOS 15.1)
How to check the battery on your iPhone using standard methods
There is a standard way to check battery health. The user does not need to download additional applications. The feature you need is available on your iPhone. It is enough to open the parameters of the device.
However, there is a certain limitation here.
So, this feature is only available to users who have installed iOS 12 on their smartphone. This feature is under testing, so it is not present on all phones.
To check the battery status on your iPhone in the standard way, you need to:
- Open phone settings.
- Select the item “Battery” from the list.
The battery status is shown as a percentage. So, if the indicator is 100%, it means that the battery is working at its maximum capacity. If the percentage is decreasing, the user has to charge his device more often.
If there is no “Battery Status” line in the Battery section, then the feature is not provided in this operating system.
How to check how many recharge cycles the iPhone by regular means
This is not so easy to do, you will need to work with the files.
- First, open Settings on your iPhone.
- Select the Privacy section.
- Now scroll to the bottom and select Analytics and Improvements (Analysis).
- Here, select Analytics Data (Analysis Data).
- You will see a huge list of files sorted alphabetically. Scroll down to the “log-aggregated” files and select the last one.
Note: In another file with the same name pattern, you can find the number of charging cycles of the Apple Watch. You will have two files with the same date, and one of them will have information about the Apple Watch.
- Go to the Notes app.
- Paste the text of the document into the note.
- Now click the “Share” icon or the three dots in the upper right corner.
- Select Find in Note.
- Type “batterycyclecount” without spaces in the search bar above the keyboard. Find the number right below the highlighted text. This is the number of charge cycles your battery has.
Now you know how to check the recharge cycles of your iPhone or iPad. We hope you understand the method, although it is not the most comfortable one.
When you copy and paste text, your smartphone may slow down because of the huge amount of text. Be patient because after that everything will be back to normal.
If you do not have this document, you may have analysis turned off. Activate it in the same section by moving the toggle switch for iPhone and watch to the on position and wait 1-2 days while iPhone usage statistics are collected.
There are other more convenient ways, which we will tell you about below.
Working ways to test your iPhone battery
Like any part, a battery has a life expectancy. The battery life is defined in cycles. This is the number that determines how many times the battery has been fully charged. Charging the battery from 50% to 100% counts as a half cycle, charging from 25% to 50% a quarter cycle, charging from 0 to 100% a full cycle.
If the number of cycles reaches 350-400, you can already feel the lack of battery capacity. At 500 cycles the battery capacity is reduced to 60-80% of the nominal capacity, which is present in the new batteries. 500 cycles are reached after 1.5-2 years of iPhone use.

The normal temperature for iPhone is between 0°C and 35°C
Low temperatures for iPhone Li-Ion batteries
At low temperatures (from 0°C and below) iPhone battery capacity drops by up to 40-50%. Battery capacity is restored at restored temperatures. However, a common reason to call us for service is the iPhone shutdown in freezing temperatures, the charge level indicator can vary greatly, from 60% to 5% and so on.д. The reason for this phenomenon is low temperature and battery life is coming to an end. One indication is battery replacement. A functioning battery should reduce capacity, but not turn off your iPhone.
High temperatures for Li-Ion iPhone batteries
iPhone battery degrades in high temperatures (35°C or more). If you remove the battery from your iPhone you will immediately see that the battery is “blown”, in our service we call such batteries “pregnant”. If the battery is badly heated and swollen then it will only help to replace it, it will not cure itself even if it cools down. It is extremely important not to leave iPhone in the sun or on a hot surface. The problem can be seen if you look at the display under the light there should be a replacement bulge t.к. The battery is pressing against the display.
iPhone improperly charging the battery
iPhone batteries are extremely sensitive to charge voltage. According to Wikipedia, changing the voltage by as little as 4% can almost halve the battery capacity. The charging current depends on the voltage difference between the battery and the charger and on the resistance of both the battery itself and the leads to it. In fact it says that the charger unit detects the battery voltage and adjusts the voltage given to the battery for charging. Original blocks, as well as blocks from quality manufacturers can do so, but the Chinese chargers, alas, can not, and the same applies to car chargers. If you want to prolong the life of the battery, but use a car charger, do not connect the iPhone to the charger cord at least while starting the engine, at this point the voltage may jump.
iPhone battery life
The average life of a modern smartphone Li-Ion battery is about 2 years. If you use your iPhone a lot, you’ll notice a noticeable loss of capacity after a year. It is estimated that after 500 full charge the battery capacity decreases by 20-25% (assuming that a full charge is when the device is completely discharged and then charged to 100%). If we take into account that usually we recharge our phone once per day, it means that in a year and a half you will have some problems with the battery that has lost its original capacity.
How it can manifest itself? The deterioration of the iPhone at low temperatures. it can start shutting down even in light frost. If you see that the phone shuts down when the battery is 15-25% charged, this is also evidence of a significant loss of the original capacity.
It is believed that the limit for the number of recharge cycles is a figure in the region of 1000, and it’s about 2-3 years of smartphone. A 50% capacity loss becomes critical. the battery barely lasts for a few hours. It is worth bearing in mind that using an ageing battery is not safe, so you need to worry about taking adequate measures in advance.
