Your phone’s battery health is an important factor to consider when it comes to its overall performance and lifespan. As batteries age, they naturally degrade and lose their ability to hold a charge. This can lead to shorter battery life, increased heat, and even performance issues.
There are a few different ways to check your battery health on Android. One way is to use the hidden diagnostics menu. To access this menu, open the Phone app and dial *#*#4636#*#*. This will open a menu with a variety of information about your phone, including the battery health.
Another way to check your battery health is to use a third-party app. There are a number of different battery apps available on the Google Play Store, many of which offer detailed information about your battery health. One popular option is AccuBattery.
Steps on how to check battery health on Android using the Settings menu:
- Open the Settings app.
- Scroll down and tap Battery.
- Tap the three-dot menu in the top-right corner.
- Tap Battery health.
This will show you your battery’s current health as a percentage. If your battery health is below 80%, it’s time to start thinking about replacing your battery.
If you’re using a third-party app to check your battery health, the steps may vary depending on the app. However, most apps will display your battery health as a percentage or a status indicator (e.g., good, bad, etc.).
It’s important to note that there is no single definitive way to check battery health. The methods described above can give you a good general idea of your battery’s health, but they may not be completely accurate.
