How to Check Battery Health on Xiaomi Devices: Step-by-Step Guide
Keeping track of your Xiaomi phone’s battery health is one of the best ways to extend its lifespan and maintain smooth performance. Over time, lithium-ion batteries naturally degrade, but knowing how far along yours is can help you decide whether it’s time for better charging habits—or even a replacement. In this guide, I’ll share the exact methods you can use to check your Xiaomi battery health, from built-in tools to advanced bug reports and reliable apps.
Why Battery Health Matters on Xiaomi Phones
Every time you charge your Xiaomi device from 0% to 100%, that counts as one battery cycle. Modern Xiaomi phones generally hold about 80% of their original capacity after 300–500 cycles. Once your battery dips below this threshold, you’ll likely notice shorter usage times, random shutdowns, or overheating.
Checking your battery health can:
- Help you spot early signs of battery degradation.
- Guide you in adjusting charging routines.
- Inform you if it’s time to replace the battery.
Methods to Check Battery Health on Xiaomi Devices
Different Xiaomi models and software versions provide different ways of accessing battery information. Below, I’ll walk you through the available methods—from official system tools to third-party apps.
Method 1: HyperOS Battery Protection (Best for Newer Xiaomi Devices)
If you own a recent Xiaomi phone running HyperOS, checking battery health is straightforward.
Step-by-step tutorial:
- Go to Settings > About phone > System update and confirm you’re on the latest HyperOS build.
- Open Settings and scroll down to Battery.
- Tap Battery Protection (on some models this appears as “Battery Health”).
- Here, you’ll see details like daily charge count and, on supported models, the cumulative cycle count.
📌 According to xHyperOS.com, this feature is available mainly on the Xiaomi 15 series and later, though it may roll out to more devices with future updates.
Method 2: Security App Method (For Older MIUI Devices)
Xiaomi used to include a battery health option inside the Security app, but it isn’t consistent across all MIUI versions.
Steps:
- Update the Security app: Open it, tap the gear icon in the top-right, then “About,” and update.
- Go back to the app and select the Battery tab.
- Tap Battery Health under the Battery section.
- Look for cycle count under “Battery Performance.”
⚠️ Many users report that this option is missing on newer MIUI builds.
Method 3: Dialer Code (##6485##)
This hidden diagnostic code works on several Xiaomi models:
- Open the native Phone Dialer.
- Enter
*#*#6485#*#*. - A diagnostic page will open showing multiple values:
- MB_06: Battery health status (e.g., “Good”).
- MF_02: Charging cycle count (if available).
- MF_05: Current capacity in mAh.

Method 4: Bug Report Method (Most Detailed)
If you’re comfortable digging deeper, the bug report method offers the most accurate insights.
Steps:
- Go to Settings > About phone > All specs.
- Tap the CPU section 5–7 times until you see a bug report notification.
- Accept the privacy policy and wait 1–2 minutes.
- Download the report from your notifications.
- Open File Manager > MIUI > debug log and extract the zip.
- Inside the text file, search for:
- Battery Capacity (current vs. design capacity).
- cycle count (total charges).
- healthd (extra details).
You can calculate health percentage with:
Current Capacity ÷ Original Capacity × 100
Example: A 5000mAh battery showing 4850mAh health is at 97%.

Method 5: Third-Party Applications
Although Xiaomi suggests relying on system tools, third-party apps can help track long-term trends. Accuracy may vary, but they’re convenient.
Trusted options:
- CPU-Z: Shows real-time capacity, temperature, and health info.
- AccuBattery: Tracks actual charge/discharge cycles and estimates true capacity.
- Ampere: Displays charging current and basic health status.
👉 I personally prefer AccuBattery—not because it’s perfect, but because it helps me monitor trends and charging habits. I’ve noticed how it highlights when I’m charging too often overnight, which has helped me adjust.
Common Battery Problems on Xiaomi Phones
Xiaomi devices are reliable, but users often face battery issues like:
- Sudden percentage drops (jumps from 20% to 5%).
- Overheating during gaming or charging.
- Slow charging despite fast-charger support.
- Rapid drain after MIUI/HyperOS updates.
These problems usually point to aging batteries or background software bugs.
Tips to Keep Your Xiaomi Battery Healthy
Following smart charging habits can extend your battery life:
| Tip | Why It Helps |
|---|---|
| Keep charge between 20–80% | Reduces stress on lithium-ion cells |
| Avoid extreme temperatures | Heat accelerates degradation, cold lowers efficiency |
| Use original or certified chargers | Prevents inconsistent voltage that harms cells |
| Enable Adaptive Battery & HyperOS Battery Protection | Helps manage overnight charging and power-hungry apps |
| Reduce background app activity | Prevents unnecessary drain |
I usually keep my phone between 30% and 85% and noticed that after a year, my battery health stayed at 95%—far better than when I used to charge to 100% daily.
What to Do If Your Xiaomi Battery Is in Bad Shape
If your battery health falls below 80%, you’ll probably notice poor standby times and unexpected shutdowns. At this point:
- Check warranty – Some Xiaomi phones include free battery replacement if within warranty.
- Visit an authorized Xiaomi service center – Third-party replacements are cheaper but may use non-genuine cells.
- Temporary fixes – Use power-saving modes, reduce screen brightness, and carry a power bank until replacement.

My Favorite Apps for Battery and Hardware Health
Apart from AccuBattery, I use:
- CPU-Z for detailed hardware monitoring.
- Device Info HW for checking thermal performance.
- Ampere when testing if a cable or adapter is underperforming.
These apps aren’t perfect but help me spot patterns. Once, I discovered my original cable had degraded because Ampere showed much lower current than usual.
Troubleshooting When Methods Fail
- If dialer codes don’t work, you may have a debloated MIUI build. Restore system apps to regain function.
- If bug report generation fails, update to the latest MIUI/HyperOS.
- If cycle count is missing, your model may not expose it. In that case, rely on HyperOS tools or AccuBattery.

How to check battery health on Xiaomi devices: Final Thoughts
Knowing how to check battery health on Xiaomi devices isn’t just for tech enthusiasts—it’s for anyone who wants longer-lasting performance. Whether you use the built-in HyperOS feature, hidden dialer codes, or apps like AccuBattery, the key is consistent monitoring and smart charging habits.
If your Xiaomi battery health is already below 80%, don’t wait too long—consider a replacement at an authorized center. And if your phone still holds strong, start applying the 20–80% rule today to make sure it stays that way.
