How to Fix 'Battery Percentage Not Showing' on iPhone (2024 Guide)
TL;DR: If your iPhone battery percentage isn’t showing, first check Settings > Battery > Battery Percentage and toggle it on. If that doesn’t work, restart your iPhone, update iOS, or try a force restart. For persistent issues, calibrate the battery by draining it fully and charging to 100%, or check Battery Health for degradation. Most cases are software-related and fixable without repair.
Why Is My iPhone Battery Percentage Not Showing?
I often hear from iPhone users who panic when the battery percentage disappears from their status bar. The good news? It’s rarely a hardware fault. Based on my experience and user reports, here are the common reasons:
- Settings Misconfiguration: The battery percentage toggle might be turned off, especially after an iOS update.
- iOS Version or Model Limitations: iPhone X and later (with Face ID) don’t show percentage in the status bar by default unless enabled in Settings or via the Control Center swipe-down^2.
- Status Bar Space Issues: If too many icons (like cellular signal, time, alarms) crowd the top bar, iOS automatically hides the battery percentage to save space^1.
- Software Glitches: Temporary bugs in iOS can cause the percentage to vanish or freeze.
- Battery Calibration Problems: The battery sensor might misread charge levels, showing wrong percentages or hiding the indicator entirely^4.
- Battery Health Degradation: If your battery health is below 80%, it can lead to inaccurate percentage readings or sudden drops^4.
Step-by-Step Fixes for Battery Percentage Not Showing
1. Check Battery Percentage Settings
This is the first thing I always recommend. Sometimes the simplest solution is overlooked:
- Go to Settings > Battery.
- Toggle on Battery Percentage^2.
- On iPhones with Face ID (iPhone X and later), the percentage appears inside the battery icon when enabled. On older models, it shows next to the icon.
2. Restart Your iPhone
A quick restart can resolve minor software glitches:
- Press and hold the Side button + either Volume button until the power slider appears.
- Slide to power off, wait 30 seconds, then turn it back on.
- Check if the battery percentage reappears.
3. Force Restart (Hard Reset)
If a normal restart doesn’t work, try a force restart. It clears temporary cache without deleting data:
- iPhone 8 or later: Quickly press and release Volume Up, then Volume Down, then hold the Side button until the Apple logo appears.
- iPhone 7/7 Plus: Hold Volume Down + Side buttons until the Apple logo shows.
- iPhone 6s or earlier: Hold Home + Side buttons until the Apple logo appears.
4. Update iOS
Outdated iOS versions can have bugs affecting battery display:
- Go to Settings > General > Software Update.
- Download and install any available updates.
- After updating, check if the percentage is visible.
5. Calibrate Your Battery
Battery calibration fixes inaccurate percentage readings^4:
- Drain your battery completely until the iPhone shuts off.
- Leave it off for at least 30 minutes.
- Charge it to 100% without interruption (use a wired charger for best results).
- Keep it plugged in for another hour after reaching 100%.
- Turn it on and check the percentage.
6. Check Battery Health
Poor battery health can cause percentage issues:
- Go to Settings > Battery > Battery Health.
- If Maximum Capacity is below 80%, your battery may need replacement^4.
- If you see a message like “Service Recommended,” visit an Apple Service Center.
7. Reset All Settings
This resets preferences without erasing data:
- Go to Settings > General > Transfer or Reset iPhone.
- Tap Reset > Reset All Settings.
- Enter your passcode and confirm. This will reset network, display, and privacy settings but keep your files intact.
8. Use Control Center to Check Percentage
On newer iPhones (iPhone X and later), you can quickly check battery percentage by swiping down from the top-right corner to open Control Center. The percentage is displayed next to the battery icon there^2.
9. Check for Physical or Charging Issues
Sometimes the problem is with the charger or cable:
- Try a different Lightning cable or wireless charger.
- Clean the charging port gently with a dry brush.
- Avoid using third-party chargers that aren’t MFi-certified.
10. Contact Apple Support
If none of the above work, there might be a hardware issue:
- Use the Apple Support app or website to schedule a diagnostic.
- If under warranty, you might qualify for a free battery replacement.
Common Mistakes to Avoid
- Ignoring iOS Updates: Many users delay updates, but they often contain bug fixes for battery display issues.
- Using Non-Certified Chargers: These can disrupt battery calibration and cause percentage errors.
- Frequent Force Restarts: While helpful occasionally, overdoing it can lead to iOS instability.
- Not Checking Battery Health: Ignoring degraded battery health can worsen percentage accuracy over time.

Step-by-Step: How to Calibrate Your iPhone Battery
I’ve found that calibration is often the most effective fix for persistent percentage issues, especially if your battery health is still above 80% but readings are erratic. Here’s how I do it:
- Drain the battery completely: Use your iPhone normally until it powers off on its own. Don’t plug it in until it’s fully dead.
- Leave it off for at least 30 minutes: This ensures the battery is fully depleted and resets the sensor.
- Charge to 100% without interruption: Use an Apple or MFi-certified charger and avoid using the phone while charging.
- Keep it plugged in for an extra hour: Even after it hits 100%, leave it connected to balance the cells.
- Restart your iPhone: Hold the side button and volume down (or home button on older models) until the Apple logo appears.
This process realigns the software’s perception of the battery’s actual capacity, which often resolves percentage inaccuracies or sudden drops ^3.
Pros and Cons of Common Fixes
| Fix | Pros | Cons |
|---|---|---|
| Restart iPhone | Quick, no data loss | Temporary fix for some |
| Update iOS | Addresses bugs, improves stability | May introduce new issues rarely |
| Battery Calibration | Resets sensor, long-lasting solution | Time-consuming (takes hours) |
| Reset All Settings | Fixes deeper software glitches | Erases Wi-Fi, display prefs |
| New Charger/Cable | Rules out power delivery issues | Cost if replacement needed |
Comparison: Built-in vs. Widget Battery Percentage
I sometimes use the battery widget for a more detailed view, especially with multiple devices:
- Status Bar Percentage: Always visible (if enabled), minimal space, but only shows iPhone.
- Battery Widget: Shows iPhone, AirPods, Apple Watch, but requires swiping to Control Center or home screen.
If your status bar percentage disappears, the widget is a handy backup—just swipe right on the home screen or lock screen to check it [^2][^10].
When to Seek Professional Help
If you’ve tried all fixes and your battery health is below 80%, it’s likely a hardware issue. I learned this the hard way when my iPhone 11’s battery swelled slightly and caused percentage jumps. Apple Support can run remote diagnostics or recommend a battery replacement, which costs around $69–$89 for out-of-warranty models ^4. Don’t ignore persistent problems—it’s better to get it checked than risk further damage.
Final Thoughts
From my experience, most percentage issues are software-related and fixable at home. Start simple, then escalate to calibration or resets if needed. And always use MFi-certified accessories—I’ve seen third-party chargers cause more problems than they solve. If you’re still stuck, drop a comment below; I’m happy to help troubleshoot based on your specific model and iOS version!
Step-by-Step: How to Calibrate Your iPhone Battery
I’ve found calibration to be one of the most effective long-term fixes for percentage inaccuracies. Here’s how I do it:
- Drain the battery completely: Use your iPhone normally until it powers off on its own.
- Wait a few hours: Leave it off for at least 3–4 hours to ensure it’s fully depleted.
- Charge to 100% uninterrupted: Plug it into a reliable charger (MFi-certified, as I mentioned earlier) and don’t use it until it hits 100%.
- Leave it plugged in a bit longer: Keep it charging for another 1–2 hours after reaching 100% to balance the cells.
- Restart your iPhone: Hold the side button (or volume + side on newer models) and swipe to power on.
This process resets the battery’s internal sensor and often resolves wild percentage swings or sudden drops ^3. It’s time-consuming but worth it if simpler fixes don’t stick.
Pros and Cons of Battery Calibration
| Pros | Cons |
|---|---|
| Long-lasting fix for percentage inaccuracies | Takes several hours (often 6+ hours) |
| No cost involved | Requires planning (can’t use phone during process) |
| Works on all iPhone models | May need repeating if issues persist |
| Addresses both software and minor battery wear | Not a fix for severely degraded batteries |
When Calibration Isn’t Enough
If calibration doesn’t help—like in my iPhone 11 case—it’s often a sign of deeper hardware issues. I always check Settings > Battery > Battery Health first. If it’s below 80%, a replacement is usually necessary ^4. For persistent problems even with good health, consider visiting an Apple Store or authorized service provider. They can run diagnostics that we can’t do at home, identifying issues like faulty battery sensors or power management chips.
Remember: calibration is a maintenance step, not a cure-all. If your battery is old or damaged, no amount of software tweaking will fully restore accuracy.
