Phone Charging Slowly After Android Update – 25 Proven Fixes (2026 Guide)
Did your Android phone begin charging much slower after installing a recent Android update? Are you seeing messages like "Charging Slowly" or noticing that your phone no longer reaches 100% as quickly as before?
Many users experience slower charging after major Android updates. In most cases, the issue is caused by temporary software optimization, battery protection features, background apps, charging accessories, or charging port problems rather than permanent hardware damage.
This guide works for Samsung Galaxy, Google Pixel, Xiaomi, Redmi, POCO, OnePlus, Motorola, Vivo, Oppo, Realme, Nokia, Sony, Asus, Nothing Phone, and most Android smartphones running Android 13, Android 14, Android 15, Android 16, and newer versions.

Why Is My Phone Charging Slowly After an Update?
Common reasons include:
- Background app optimization after the update
- Battery protection or adaptive charging features
- Fast charging disabled in settings
- Damaged USB cable or charger
- Dirty USB charging port
- Phone overheating while charging
- Battery health degradation
- Software bugs introduced by the update
- Charging while using power-intensive apps
- Faulty charging adapter
25 Ways to Fix Slow Charging After an Android Update
1. Restart Your Phone
A simple restart clears temporary processes that may affect charging performance.
2. Wait 24–48 Hours After the Update
Android often performs background optimization after major updates, which can temporarily affect charging speed and battery performance.
3. Use the Original Charger
Use the charger and USB cable supplied by the manufacturer or a certified replacement that supports your phone's charging standard.
4. Inspect the Charging Cable
Replace damaged, loose, or worn cables that may reduce charging speed.
5. Clean the Charging Port
Dust and lint inside the USB port can prevent proper electrical contact. Clean the port carefully using a non-metallic tool or compressed air.
6. Check Fast Charging Settings
Go to Settings → Battery and verify that Fast Charging or Super Fast Charging is enabled if your device supports it.
7. Charge from a Wall Outlet
A wall charger usually delivers more stable power than a laptop USB port or inexpensive power strip.
8. Avoid Using the Phone While Charging
Gaming, video streaming, and navigation increase power consumption and slow charging.
9. Close Background Apps
Reduce CPU activity by closing unnecessary apps before charging.
10. Disable Battery Saver While Charging
Some phones manage charging differently when Battery Saver is enabled.
11. Turn Off Bluetooth, GPS, and Mobile Hotspot
Disabling unused wireless features reduces heat generation and power consumption.
12. Remove the Phone Case if It Gets Hot
Excessive heat may trigger charging protection that reduces charging speed.
13. Let the Phone Cool Down
If the phone feels unusually warm, allow it to cool before charging again.
14. Update All Apps
Outdated apps may continue heavy background activity after a system update.
15. Install the Latest Android Patch
Manufacturers often release follow-up updates to fix bugs introduced by major Android upgrades.
16. Check Battery Health
A degraded battery may charge more slowly than when it was new.
17. Try Another Certified Charger
Testing with another compatible charger helps determine whether the charger is causing the problem.
18. Try Another USB Cable
Many slow charging issues are caused by worn or low-quality cables.
19. Enable Airplane Mode While Charging
This reduces background network activity and can slightly improve charging speed.
20. Boot into Safe Mode
If charging returns to normal in Safe Mode, a third-party app may be interfering.
21. Reset Battery Settings (If Supported)
Some manufacturers provide battery optimization reset options.
22. Reset All Settings
This restores system settings without deleting personal files on many Android devices.
23. Factory Reset (Last Resort)
24. Replace the Battery
If the battery health is poor, replacement may restore normal charging performance.
25. Contact the Manufacturer
If slow charging began immediately after an update and persists despite troubleshooting, contact the device manufacturer's support team.
How to Restore Fast Charging
| Problem | Recommended Solution |
|---|---|
| Fast Charging Not Working | Enable Fast Charging in settings and use a compatible charger. |

How to Prevent Slow Charging
- Use original or certified charging accessories.
- Keep the charging port clean.
- Avoid charging in direct sunlight or hot environments.

Frequently Asked Questions (FAQ)
Why did my phone start charging slowly after an Android update?
Major Android updates often trigger background optimization and indexing. Temporary software bugs, battery protection settings, or charging accessory issues can also contribute.
Can software updates affect charging speed?
Yes. Although uncommon, software changes may temporarily affect charging behavior until optimization is complete or a bug-fix update is installed.
Why does my phone say "Charging Slowly"?
This message usually indicates insufficient charging power, a damaged cable, an incompatible charger, or charging port issues.
Should I replace my charger?
If testing with another certified charger resolves the issue, replacing the original charger or cable is recommended.
Does heat slow down charging?
Yes. Most modern Android phones automatically reduce charging speed to protect the battery when temperatures become too high.
When should I replace the battery?
If charging remains slow and battery health has significantly declined, replacing the battery may restore normal charging performance.
Conclusion
Slow charging after an Android update is usually caused by temporary system optimization, charging accessories, battery protection features, or software bugs rather than hardware failure. Start by waiting for post-update optimization to finish, then check your charger, USB cable, charging port, and battery settings.
If the problem continues after trying these solutions and installing the latest software updates, check battery health or contact your phone manufacturer's support team for further assistance.
