How to Check Your iPhone’s Battery Health and Usage


With Apple’s admission that they had released a feature in their latest operating system to manage their device’s power, many are wondering how to check battery health of iPhone. Apple stated that this feature slowed down older versions of their iPhones to stop them from turning off suddenly. This recent feature was included in iOS versions 10.2.1 for the iPhone 6 series, as well as in the version 11.2 for both the iPhone 7 and 7 Plus.

How Does the New Feature Work?

According to Apple, the power management system functions by taking into account the battery’s current charging state, its impedance, as well as the overall temperature of the device itself. Basically, this new feature will cause your iPhone to work slowly if the said factors require it. This doesn’t mean that your phone’s battery, regardless of whether it is new or a refurbished one bought from QwikFone, has degraded rather that the combination of factors demands for the device to work slowly. 

Tips on How to Check iPhone Battery Health

With Apple releasing this feature in their latest operating systems, it is only fair for us to check the condition of our phone’s battery health. Fortunately, there are several ways to do this such as those listed below. 

Install coconutBattery Application 

The first method to determine the health of your iPhone’s battery is through the coconut Battery application. Here’s what you should do.
  • Connect your device to your Apple computer using the Lightning cable that comes with your phone. 
  • Download the application on your computer then activate it. 
  • You can now review your battery’s current condition through this application. Among the details that you will see here are the battery’s capacity, capacity for being fully charged, and the health of your phone’s battery just to name a few. 
Install Third-Party Applications 

If you want to check your iPhone’s battery health and usage, you’ll be happy to know that there are several third-party applications that can be used. One example is the Battery Life application which is available from Apple’s store. Here’s how to use it. 
  • Download the application which you can get without paying a fee. 
  • Launching the application will display the wear level of your iPhone’s battery on its display. This will give you a clear idea on the current status of your battery and whether it is time for you to get a new one. 
  • Go to the menu then press Raw Data. This will give you access to the battery’s current capacity. 
Console Application 

What other methods can you use to determine the current status of your iPhone’s battery? By using the console application, that’s how.
  • Attach your iPhone to your computer with the aid of the Lightning able. 
  • Double click on the Console application on your Mac. 
  • Look for Battery Health among the list of options. See to it that your device remains unlocked through this process, and that your computer trusts it. 
  • A search field can be found in the Console application where you should type the word batteryhealth. Move the cursor on the iPhone device found in the left side of the screen. Here you will find the battery’s recent status. 
Settings Application 

Apple has been sending out notices to their users, whose phones are currently equipped with iOS version 10.2.1 or older, that the battery of their device may require servicing by running diagnostics. To do this, you will need to follow these steps.
  • Head to your device’s Settings application. 
  • Tap on Battery to determine if the battery requires replacement. 
  • There are two important indicators here (especially if your iPhone is equipped with iOS version 11.3) which are the Maximum Capacity as well as capability for peak performance. 
  • The battery for newer iPhones should be in good shape and must be near the maximum capacity. If not, it may mean that the battery has a defect which you can determine if you take a look at the battery health display. 
Understanding Maximum Capacity 

As the name suggests, maximum capacity means that the battery’s operating capacity is at 100%. However, this capacity will go down after years of use, and undergoing numerous charging cycles. Basically, the farther the indicator is from the maximum capacity, the less battery charge will be available for you to use. 

However, just because the number is below the maximum output, it doesn’t mean that there is something wrong with the battery installed in your iPhone. What this means is that it is less than the original capacity. It is possible for you to determine the cycle count for your battery with the aid of a profiler for your device’s System Information, or by downloading third party applications. 

Peak Performance Capability – What Is It? 

This section gives you insight on the problems that the battery is currently facing, including whether these issues are affecting your device’s performance. Newer handsets from Apple will display a message that the battery is supporting normal performance. If any other messages appear, it may indicate that there is something wrong with the battery already. 

If you feel that your device is not performing well, you can check the peak performance if there are any issues. When a message that says that the performance management is currently activated, it means that the device has rebooted because there was a problem with the battery. 

Battery performance is currently limited to certain iPhone devices that are equipped with older operating systems. This is because the performance of the device may get affected with battery issues which can cause their iPhones to crash or reboot on its own. 

If you see a message that the device can no longer check the health of its battery, you can have your phone serviced or have its battery replaced so you can use your iPhone a bit longer. 

Following the methods mentioned above can give you a better understanding on your battery’s current state. If you feel that your iPhone is starting to slow down or is crashing suddenly, there might be an issue with its battery. Having it checked or serviced can help determine the cause for you.
