Many smartphone users have experienced the frustrating situation where their device’s battery charging halts unexpectedly at around 85 percent. This issue can be caused by a variety of factors, including software glitches, battery health, or charger problems. Understanding the root causes and knowing how to troubleshoot effectively can help you resolve this problem and ensure your phone charges fully and efficiently. In this article, we will explore the common reasons behind a phone getting stuck at 85 percent during charging and provide practical solutions to fix it.
How to Fix Phone Charging Stuck at 85 Percent
1. Understand Why Your Phone Stops at 85 Percent
Before diving into fixes, it’s essential to understand why your phone might stop charging at 85 percent. Modern smartphones often incorporate battery management features designed to prolong battery lifespan. These features sometimes intentionally limit charging to around 85 percent during certain conditions.
- Battery Optimization Settings: Many devices, especially Android phones, include settings that optimize battery health by slowing or stopping charging at around 80-85% during certain scenarios.
- Smart Charging Features: Some phones have “adaptive” or “optimized” charging modes that delay full charge until you need it, reducing battery aging.
- Battery Health and Wear: A deteriorating battery may not charge beyond a certain point due to capacity loss or safety concerns.
- Charger or Cable Issues: Faulty or incompatible chargers and cables can cause incomplete charging cycles.
- Software Glitches: Outdated firmware or software bugs can interfere with proper charging behavior.
2. Check Your Phone’s Battery Settings
Many devices include built-in features to protect battery longevity, which could be responsible for stopping the charge at 85 percent. Adjusting or disabling these settings can help resolve the issue.
-
Android Devices:
- Go to Settings > Battery > Battery Health or Optimization.
- Look for options such as Adaptive Charging, Battery Care, or similar features.
- Disable these features temporarily to see if the charging completes to 100%.
-
iPhones:
- Navigate to Settings > Battery > Battery Health & Charging.
- Disable Optimized Battery Charging and check if the phone charges fully.
Note: If disabling these features resolves the problem, consider re-enabling them once you’ve charged the battery fully to maintain battery health.
3. Perform a Soft Reset or Restart
Software glitches can sometimes interfere with the charging process. Performing a soft reset or restart can clear temporary bugs and refresh your device’s system.
- Hold down the power button until the options menu appears.
- Select Restart or Reboot.
- Allow your device to restart and then connect it to the charger again.
Check if the phone now charges beyond 85 percent. If not, proceed to other troubleshooting steps.
4. Use a Different Charger and Cable
Faulty or incompatible chargers and cables are common culprits for incomplete charging cycles. Test with different accessories to rule out hardware issues.
- Use the original charger and cable that came with your device if possible.
- Try a different charger and cable that are compatible with your phone’s specifications.
- Ensure that the charger provides the correct voltage and current output (e.g., 5V/2A).
- Inspect cables for visible damage or fraying.
If your phone charges fully with a different charger or cable, replace the faulty accessory permanently.
5. Clean the Charging Port
Dust, lint, or debris in the charging port can interfere with proper electrical contact, causing charging interruptions or incomplete charging.
- Turn off your device.
- Use a small, soft brush or a dry toothpick to gently remove debris from the port.
- Avoid using liquids or sharp objects that could damage the port.
- After cleaning, reconnect the charger and monitor the charging process.
Regular cleaning can prevent future charging issues related to port obstruction.
6. Update Your Device’s Software
Software bugs can affect how your phone manages charging. Keeping your device’s firmware up to date ensures you have the latest fixes and improvements.
- Go to Settings > Software Update.
- Download and install any available updates.
- Restart your device after updating.
Once updated, connect your phone to the charger and check whether it charges beyond 85 percent.
7. Calibrate Your Battery
Battery calibration helps your device accurately report the remaining battery percentage, which can sometimes fix charging display issues.
- Charge your phone to 100% and keep it plugged in for an additional 30 minutes.
- Use your phone normally until it completely discharges and turns off.
- Charge it uninterrupted back to 100% without turning it on during charging.
- Repeat this process once or twice to recalibrate the battery sensor.
This process doesn’t physically repair the battery but can resolve inaccurate percentage readings and charging behavior.
8. Check Battery Health and Replace if Necessary
If your battery is old or degraded, it may not charge fully or hold a charge effectively. In such cases, replacing the battery can resolve the issue.
- Use built-in diagnostics (if available) or third-party apps to evaluate battery health.
- If the battery health is below 80%, consider visiting a certified technician for replacement.
- Always opt for genuine replacement batteries to ensure compatibility and safety.
Replacing an aging battery often restores full charging capability and improves device performance.
9. Factory Reset as a Last Resort
If all else fails, performing a factory reset can eliminate software issues causing the charging problem. Before doing this, back up all important data.
- Go to Settings > General Management > Reset > Factory Data Reset.
- Follow on-screen instructions to complete the reset.
- After resetting, set up your device and test the charging process.
Note: Factory reset erases all data, so ensure you’ve backed up your information beforehand.
Conclusion: Ensuring Proper Charging and Battery Health
Encountering a phone that gets stuck charging at 85 percent can be frustrating, but most issues are resolvable through systematic troubleshooting. Start by reviewing your device’s battery settings and updating software. Try cleaning the charging port, switching charging accessories, and performing resets if necessary. Keep in mind the importance of battery health; if your battery is old or damaged, replacing it may be the best long-term solution. By understanding the causes and implementing these fixes, you can restore your device’s charging performance and maintain optimal battery health for longer-lasting use.
