WEB DESK, July 31(ABC): The lithium-ion battery inside your Android phone has a limited life span. Every charge-discharge cycle degrades its capacity a little (because the lithium charges zipping around the battery are lost to chemical reactions). Overheating and overcharging can accelerate the process. But eventually, all available charging cycles are used up. And the battery can no longer pull or store charge.
Although it’s impossible to prevent, you can monitor the degradation to keep your Android’s battery healthier for longer. Or, if your Android phone has a poor battery life, it’s always a good troubleshooting step to check the phone’s battery health. Android (by default) doesn’t have such checks built into it, though.
There are plenty of simple workarounds to diagnose your Android phone’s battery. You can punch in a dial code to test the battery life (via XDADevelopers). Alternatively, you can use a third-party app for a more reliable and detailed overview. Here are detailed instructions for each.
1. Open the dialler app and punch in the following code: *#*#4636#*#*.
2. As soon as you tap the * key, the Android Testing menu should pop up.
3. If you see Battery Information in the menu, tap it to view the health status of your battery.
For many phones, dialing the code might not return anything. In that case, you’ll need to download a battery app.
If you have a Samsung phone, the Samsung Members app features a battery health indicator (via Samsung).
1. Download and open Samsung Members if you don’t have it already.
2. Go to Get Help > Phone care > Interactive checks > Battery.
3. The app indicates the battery health as good or poor next to Life.
