Why Does My Phone Stop Charging at 85


Why Does My Phone Stop Charging at 85?

In today’s world, smartphones have become an essential part of our lives. We rely on them for communication, entertainment, work, and so much more. So, it can be quite frustrating when our phones stop charging at a certain percentage, often around 85%. This issue has left many users wondering why their phones are behaving this way. In this article, we will explore the reasons behind this phenomenon and provide some possible solutions.

1. Battery Optimization:
One of the primary reasons why your phone stops charging at 85% is battery optimization. Smartphone manufacturers have implemented advanced algorithms to prolong battery life. These algorithms ensure that the battery is not constantly charged to 100% as it can degrade the battery’s overall health over time. stopping the charging process at around 85%, the manufacturers aim to strike a balance between battery longevity and ensuring sufficient charge for daily use.

2. Battery Calibration:
Another reason could be the battery calibration. Over time, your phone’s battery may lose accuracy in reporting its actual charge level. To address this, manufacturers often limit the charging capacity to a level slightly lower than 100%. This prevents the battery from overcharging and helps maintain its accuracy in reporting the remaining charge. Hence, your phone may stop charging at 85% even if the battery is not entirely full.

3. Battery Wear and Tear:
As with any rechargeable battery, wear and tear are inevitable. Over time, the battery’s capacity naturally decreases, resulting in reduced charging efficiency. When your phone stops charging at 85%, it could be an indication that your battery’s maximum capacity has decreased, and it can no longer hold a charge beyond that point. In this case, replacing the battery might be necessary to resolve the issue.

4. Temperature Regulation:
Temperature plays a crucial role in the charging process. To protect your phone’s battery from overheating, manufacturers have implemented temperature sensors that interrupt the charging process if the battery temperature exceeds a certain threshold. When your phone stops charging at 85%, it could be due to the battery getting too warm during the charging process. This mechanism ensures the battery’s safety and prevents damage caused by excessive heat.

5. Faulty Charging Cable or Adapter:
Sometimes, the issue lies not with the phone or battery but with the charging accessories. A faulty charging cable or adapter can disrupt the charging process and cause your phone to stop charging prematurely. Try using a different cable and adapter to see if the issue persists. If the problem is resolved, it indicates that the previous accessories were causing the limitation.


Q: Is it bad to charge my phone to 100%?
A: Charging your phone to 100% occasionally is not harmful. However, continuously charging it to maximum capacity can degrade the battery’s overall health over time.

Q: Can I override the charging limitation?
A: While it is technically possible to override the charging limitation, doing so may significantly reduce your battery’s lifespan. It is recommended to follow the manufacturer’s guidelines for optimal battery health.

Q: How can I improve my battery performance?
A: To improve battery performance, you can try reducing screen brightness, disabling unnecessary background apps, and using power-saving modes. Additionally, avoid extreme temperature conditions as they can affect battery life.

Q: Should I replace the battery if my phone stops charging at 85%?
A: If your phone stops charging at 85% consistently and other troubleshooting steps fail, it might indicate a battery issue. In such cases, it is advisable to consult a professional or contact the phone’s manufacturer for battery replacement options.

In conclusion, the charging limitation at 85% is primarily a result of battery optimization, calibration, wear and tear, temperature regulation, or faulty charging accessories. While it may be frustrating to experience, these mechanisms are in place to ensure the longevity and safety of your phone’s battery. If you encounter this issue, try the suggested troubleshooting steps, and if necessary, seek professional assistance for further evaluation and resolution.
