If you want to know how your Android phone's battery is performing, you need to check its battery health. Battery health is a measure of how much the battery capacity has degraded over time. A low battery health means your phone will run out of power faster, and may also experience overheating or swelling issues.
In this article, we will show you how to check battery health in Android using different methods. We will also give you some tips on how to improve your battery health and extend its lifespan.
Method 1: Using the Settings Menu
One of the easiest ways to check battery health in Android is to use the built-in settings menu. This method works for most Android devices, but the level of detail may vary depending on the manufacturer and model of your phone.
To check battery health in Android using the settings menu, follow these steps:
- Open the Settings app on your phone, then select Battery.
- Here you can see your battery status over the last 24 hours, and which apps have been using the most power.
- If you want to see more details, look for an option such as Battery usage or Battery health. You may need to tap More settings or Advanced settings to find it.
- Here you can see your battery capacity, which is the percentage of the original capacity that your battery can hold. For example, if your battery capacity is 80%, it means your battery can only store 80% of the power it could when it was new.
- You can also see other information such as your battery temperature, voltage, and cycles. The temperature should be below 50 degrees Celsius (122 Fahrenheit) to avoid overheating. The voltage should be between 3.7V and 4.2V to avoid overcharging or undercharging. The cycles are the number of times you have charged and discharged your battery. A typical lithium-ion battery can last for about 500 cycles before its capacity drops significantly.
Method 2: Using a Dial Code
Another way to check battery health in Android is to use a hidden diagnostic menu that you can access by entering a code in the phone dialer. However, this method may not work on all devices and networks, so you may need to try different codes to find the one that works for you.
To check battery health in Android using a dial code, follow these steps:
- Open the Phone app and enter ##4636##. This will open a Testing menu that may include a Battery information section.
- Here you can see your battery health, which is either Good, Normal, or Poor. You can also see other information such as your battery level, voltage, temperature, and technology.
- If this code doesn't work for you, you can try other codes such as ##7378423##, ##6485##, or *#0228#. You may need to search online for more codes that are compatible with your device and network.
Method 3: Using a Third-Party App
If none of the above methods work for you, or if you want more detailed and accurate information about your battery health, you can use a third-party app from the Play Store. There are many apps that can help you monitor your battery health, but one of the best ones is DevCheck.
To check battery health in Android using DevCheck, follow these steps:
- Download and install DevCheck from the Play Store.
- Open the app and navigate to the Battery tab at the top of the screen.
- Here you can see your battery health, which is calculated based on your current capacity and design capacity. You can also see other information such as your charge level, voltage, temperature, cycles, wear level, and estimated time remaining.
- You can also tap the History button at the bottom of the screen to see graphs of your battery usage, charge rate, temperature, and voltage over time.
Tips on How to Improve Battery Health
Now that you know how to check battery health in Android, you may wonder how to improve it and extend its lifespan. Here are some tips that can help you do that:
- Avoid extreme temperatures. High or low temperatures can damage your battery and reduce its capacity. Try to keep your phone between 10°C and 35°C (50°F and 95°F).
- Avoid fast charging or wireless charging. These methods can generate more heat and stress your battery. Use a standard charger or a slow charger instead.
- Avoid overcharging or undercharging. Don't leave your phone plugged in for too long after it reaches 100%, or let it drop below 20%. Try to keep your battery between 40% and 80% most of the time.
- Avoid using power-hungry apps or features. Turn off unnecessary features such as Bluetooth, GPS, Wi-Fi, or mobile data when you don't need them. Close or uninstall apps that drain your battery in the background. Adjust your screen brightness and timeout settings to save power.
- Perform regular maintenance. Calibrate your battery once in a while by draining it to 0% and charging it to 100% without interruption. This can help reset the battery meter and improve its accuracy. You can also use apps like DevCheck to monitor your battery health and performance.
Conclusion
Checking battery health in Android is important to know how your phone's battery is performing and how long it will last. You can use different methods to check battery health in Android, such as the settings menu, the dial code, or the DevCheck app. You can also follow some tips to improve your battery health and extend its lifespan.
