Nowadays, checking the battery status on an iPhone is an essential part of ensuring the device’s performance and avoiding unnecessary issues. This article by FPT Shop will guide you through 4 simple and easy ways to check if your iPhone battery has been replaced and how to promptly address any issues.

1. Why should you check if the iPhone battery has been replaced?

The battery is a crucial part of an iPhone, and using a low-quality battery can affect both the performance and lifespan of the device. When the battery has been replaced, especially with a non-genuine battery, it can lead to issues such as reduced usage time, causing frustration.

When buying a used iPhone, checking the battery is the first important step. If the battery has been replaced, it may indicate that the phone has undergone disassembly, which can reduce its water and dust resistance capabilities. Moreover, replacing the battery with an unknown source, unbranded, cheap, or low-quality battery can cause the battery to swell, affecting the device’s performance and posing a risk of explosion when used for an extended period.

In general, using non-genuine or used batteries poses significant risks. Especially non-genuine batteries may not be manufactured according to safety standards, resulting in the risk of explosions or heat generation. That’s why many people try to check if the iPhone battery has been replaced to detect and promptly address any issues.

2. Checking the battery status on an iPhone

You can check the battery status on an iPhone with the following basic steps:

Step 1: Open the Settings app → select the Battery section.

Step 2: Next, select Battery Health & Charging and check the battery capacity in the Maximum Capacity section.

If the battery capacity percentage is above 80%, it indicates that the battery on the iPhone is still in good condition and does not need to be replaced. Conversely, if it is below 80%, it means you should invest in a new battery to ensure performance throughout the usage.

3. Observing the exterior and screws

The simplest way to check if the iPhone battery has been replaced is to observe the exterior and check the external shell and screws to determine if the battery on the iPhone has been tampered with. If the phone has been opened to replace the battery, you may notice the following signs:

  • Some screws are stripped or deformed.
  • The external shell of the phone is scratched or dented (although this condition may sometimes be due to the use of accessories such as phone cases).

However, it is important to note that observing the external shell and screws is only for reference and does not guarantee absolute accuracy. Nevertheless, this can still be a useful method to identify whether the battery has been replaced, especially in cases where the person replacing the battery has poor craftsmanship.

4. Checking the iPhone battery status using software

Another common way to check if the iPhone battery has been replaced is to use software, specifically the following software:

Checking with Analytics Data software

The process of checking if the iPhone battery has been replaced using the Analytics Data software includes the following steps:

Step 1: Access the Settings menu on the phone → select Privacy → select Analytics & Improvements.

Step 2: In the Analytics Data section on the phone, look for the log-aggregated-[current date being checked] entry. Then, take note of the following information:

  •  apple.power.battery.cycle_count: This line displays the number of times the battery has been fully charged to 100%. For example, if the number is 408, it means the phone has been fully charged 408 times.
  •  apple.power.battery.design_capacity: This line shows the original capacity of the battery. For example, the iPhone 7 has a battery capacity of 1960 mAh.
  •  apple.battery.raw_max_capacity: This line shows the remaining capacity of the battery at the time of the check compared to the initial capacity provided by the manufacturers. For example, if the remaining capacity is 1840 mAh compared to the 1960 mAh of the iPhone mentioned above, it means the capacity is about 94%. There are cases where this capacity is higher than the original capacity, indicating that the battery has been replaced with a higher capacity battery from a third party.

Checking with iTools software

You can check if the iPhone battery has been replaced using the iTools software as follows:

Step 1: Download the iTools application from the official website. After installation, open the application and connect your phone to a desktop or laptop computer using a USB cable.

Step 2: In the iTools application interface, select Device Verification and check the information about the components.

  • If all statuses are displayed as Normal, it indicates that all the components have not been replaced.
  • If any item appears with the status Abnormal, it indicates a problem with that component.

Using iTools to check the status of the components on the phone is quite convenient and helps you quickly determine whether they have been replaced or not.

Checking with 3uTools software

3uTools is also an effective tool that helps you check if the iPhone battery has been replaced. Here’s how:

Step 1: Download and install the 3uTools software from the official website. After installation, open the application and connect your phone to a computer.

Step 2: In the 3uTools application interface, select Verification Report → click on the option Authorize to View to view the report on the status of the components on the phone.

Step 3: Check the status of the components on the phone, including the battery.

  • If all components are displayed with the status Normal, it indicates that all the components are still in normal condition.
  • Alternatively, if any component appears in red, it means that component has been replaced.

Checking with iBackupBot software

You can check if the iPhone battery has been replaced using the iBackupBot software as follows:

Step 1: First, download and install the iBackupBot software on your computer.

Step 2: After installation is complete, connect your iPhone to the computer via USB and open the iBackupBot software. Select the iPhone folder and then select More Information.

Step 3: In the pop-up dialog box, select the Battery section to view information about the iPhone battery, including:

  • CycleCount: This line displays the number of times the iPhone battery has been fully charged to 100%.
  • DesignCapacity: This line shows the original capacity of the battery.
  • FullCharge Capacity: This line shows the current maximum capacity of the battery.

For the iPhone Battery Testing application

Step 1: Download and install the Battery Testing application on your iPhone.

Step 2: Open the application, then select Device → Battery. The application will display the battery usage time and the current battery level of your iPhone.

The Battery Testing application also provides the ability to test the actual battery usage time by:

  • Selecting Battery → Start Test and waiting for about 3 minutes to receive the evaluation result.
  • If the evaluation score is below 40%, you should consider replacing the battery for your iPhone.

5. How to check if the iPhone battery has been replaced in iOS 15.2

You can check if the iPhone battery has been replaced directly on the phone by updating to the iOS 15.2 software version or newer. To perform these steps, simply follow these steps:

Step 1: Access General in Settings to check if your iPhone has been updated to iOS 15.2 or a newer version.

Step 2: Tap Software Update to update iOS to version 15.2 or newer.

Step 3: After the iPhone completes the software update process, go to General → select About.

Case 1: If the battery has been replaced using Apple’s genuine parts and procedures, the status will display Genuine Apple Part.

The message Unknown Part will appear if the battery replacement process is incomplete or if a non-genuine, used battery from another device or a malfunctioning battery is installed. An additional message “Apple has updated the device information for this iPhone” may also appear to indicate that Apple has updated the device information for maintenance and safety analysis purposes.

Case 2: If no information is displayed in the About section, it indicates that the iPhone has not had any components replaced.

6. How to check if the iPhone battery is genuine or not

Checking with Settings

Step 1: Open the Settings app on your iPhone.

Step 2: Select the Battery section, and you will see the remaining battery percentage displayed in the Maximum Capacity section.

Direct usage

Step 1: Charge your iPhone to 100% and use it until the battery level drops to 5-7%, then open a heavy game to test.

Step 2: If the phone shuts down due to low battery when the battery level drops to 3-4%, it is a sign that the battery has degraded.

Step 3: Repeat this process several times to ensure accurate results. When buying a phone, choose reputable brands to avoid purchasing low-quality products.

Checking with the Battery Life app

Step 1: Download the Battery Life app from the App Store on your phone.
