Easy Ways to Know When Its Time to Replace Your Phone Battery

Is your phone's battery draining faster than usual? It might be time to replace it. But how do you know when it's officially time to say goodbye to your old battery and hello to a new one? Here's the easiest way to check!

Check if your iPhone battery needs replacing

iPhone has a built-in battery health check that provides valuable insights into battery performance and capacity. It compares your iPhone's current battery health to its original state, making it easy to determine when it's time to replace your battery.

To check battery health on iPhone:

1. Open the Settings app and scroll down to tap Battery .
2. Tap Battery & Charging Status .
3. Check the percentage value next to Maximum Capacity .

Battery status and charge capacity in iPhone Settings

If your iPhone's maximum battery capacity is below 80%, you should consider replacing the battery, especially if it's not lasting as long as it used to. In this case, your iPhone will also display a message at the top of the Battery Health page suggesting a replacement.

If you paid for AppleCare+, you should be eligible for a free battery replacement. If not, you'll need to explore other options to replace your iPhone battery .

Check if your Android phone battery needs replacing

Unlike iPhones, Android phones don't offer a native option to check battery health. However, there are several methods you can use to assess the health of your Android phone's battery.

1. Using a third-party app

One of the easiest and most popular ways to check your battery health on Android is to use a third-party app called AccuBattery. This app provides detailed information about your battery's capacity, usage, and health over time.

Download and install the AccuBattery app from the Play Store. The app will measure your charge cycles to estimate the health of your battery. Note, however, that AccuBattery won't display battery health information immediately; the app takes time to monitor and collect data.

After a few charge cycles, check the battery capacity. If the capacity is significantly lower than the original capacity (usually around 80% or less), it may be time to consider replacing your phone's battery.

2. Use the Phone Diagnostics menu on your Samsung phone

If you have a Samsung Galaxy phone, you don't need to use a third-party app to check the health of your battery. Instead, you can use the Phone Diagnostics option in the Samsung Members app to determine if your battery needs to be replaced. Here's how:

• Download and install the Samsung Members app from the Play Store if you haven't already.
• Go to the Support tab and click on Phone Diagnostics .
• Click Battery status to run diagnostics.

If the app shows a status of "Normal" and says the battery life is "Good", you don't need to do anything. However, if the app shows the battery life as "Bad" or "Weak", you should consider replacing the battery.

3. Dial the code *#*#4636#*#*

If you have an older Android phone, you can access a hidden diagnostics menu using an Android secret code. This method may not work on every device, but it's worth a try for a quick check.

Open your phone's dialer and type *#*#4636#*#*. This will open the test menu. Then, tap the Battery Information option to see detailed information about your battery's health. If it says Bad , you may need to replace the battery.

Over time, your phone's battery will naturally degrade, affecting the overall performance and functionality of your phone. While there are signs that it's time to replace your phone battery, checking your battery's health is the most reliable way to make an informed decision.

If your battery is in good condition but your phone is still draining quickly, replacing the battery won't help. Check out these common reasons why your battery is draining quickly and take the necessary steps to fix them.
