If you are using an Android phone and your mobile charges your battery slower than usual time then it means there is a problem with your battery. One of the most common signs of low battery health is the mobile starting to heat up while using the apps.
With the use of a mobile, your battery health becomes worse. In androids, the more you use your mobile, the more you will get your battery drains. To save your battery from damage issues, you need to check your battery health time by time.
Here in this blog, we will guide you step by step on how to check Android Battery Health, and also about the hidden settings regarding your battery in your mobile. You can also use a third-party battery app to check battery health and understand the levels of battery.
What is Battery Health on Android?
Battery health refers to the condition of your battery compared to when it was new. Over time, a battery’s capacity to hold a charge reduces. For example, a phone that originally lasted 10 hours may now only last 6–7 hours after a year or two.
Good battery health means:
- Full charging capacity
- Longer screen-on time
- Less overheating
- Stable performance
Poor battery health causes:
- Fast battery drain
- Unexpected shutdowns
- Overheating and lag
- Short charging cycles
Method 1: Check Battery Health from Settings (Limited Info)
Some Android phones (like Samsung, OnePlus, or Xiaomi) provide basic battery data in the Settings app.
Steps:
- Open Settings
- Tap on Battery & device care (or Battery on some devices)
- Check Battery Usage, Screen Time, and Apps consuming battery
While this doesn’t show full “battery health,” it helps identify power-hungry apps.
Samsung Users:
- Go to Settings > Battery and device care > Diagnostics
- Tap on Battery Status
- You’ll see statuses like “Good,” “Normal,” or “Needs attention.”
Method 2: Use Android Dialer Code
Some Android phones support hidden diagnostic menus via dialer codes.
Steps:
- Open the Phone/Dialer app
- Dial this code: *#*#4636#*#*
- You’ll see a Testing menu
- Tap on Battery Information
Note:
- This menu shows battery status, health, voltage, and temperature
- Not all Android phones support this feature (may not work on newer models)
Method 3: Use a Third-Party App to Check Battery Health
For more detailed analysis, you can use trusted apps from the Google Play Store.
Recommended Apps:
AccuBattery
- Monitors real-time battery health
- Shows Battery Capacity, Charge Cycles, and Wear Level
- Alerts for ideal charging limits (80% for battery longevity)
- Easy to use and accurate
Battery Guru
- Tracks charging habits
- Offers detailed health stats
- Estimates battery life, charging speed, and temperature
CPU-Z
- Shows battery condition under the Battery tab
- Also provides system info, performance stats
How to Use:
- Install AccuBattery from the Play Store
- Open the app and charge your phone fully
- After a few charge cycles, it estimates battery health in %
- Monitor and follow the tips given in-app
Example: If your phone originally had 4000 mAh but now shows 3200 mAh, your battery health is 80%
Signs Your Android Battery Health is Poor
- Your phone shuts down at 20–30% battery
- It heats up even during light use
- It charges extremely slowly or too fast
- The battery drains quickly, even on standby
- Your screen-on time is much shorter than before
If you notice 2 or more of these, it’s time to check your battery health and possibly replace the battery.
How to Extend Android Battery Health
Even if your battery is in good shape, these tips will help prolong its life:
Smart Charging Habits
- Keep the charge between 20%–80%
- Avoid overnight charging
- Unplug once it hits 100%
Reduce Screen Brightness & Timeout
- Use adaptive brightness
- Set screen timeout to 30 seconds
Disable Unused Features
- Turn off Bluetooth, Location, and Wi-Fi when not needed
- Disable background apps and auto-sync
Use Battery Saver Mode
- Go to Settings > Battery > Battery Saver
- Turn it on during low power or travel
Avoid Heat Exposure
- Don’t use your phone in direct sunlight
- Remove the case while charging if it heats up
FAQs
Can I check the exact battery health like iPhone’s Battery Health %?
Not directly in Android settings, but apps like AccuBattery or Battery Guru can estimate it with good accuracy.
How do I know when to replace the battery?
When your battery drops below 70–75% health, it’s time to consider a replacement, especially if your phone shuts down randomly.
Will factory reset improve battery health?
No. A factory reset might improve battery performance by removing apps, but it won’t restore lost capacity.
Can fast charging damage the battery?
Fast charging is safe on modern phones, but frequent high heat from fast charging can reduce battery lifespan over time.
