Why Does My Phone Stop Charging at 85 Percent


Why Does My Phone Stop Charging at 85 Percent?

In today’s digital age, our smartphones have become an integral part of our lives. We rely on them for communication, entertainment, and staying organized. One of the most frustrating things that can happen to a smartphone user is when their phone stops charging at 85 percent. This issue leaves many wondering why it happens and if there is a way to fix it. In this article, we will explore the reasons behind this problem and provide some possible solutions.

1. Battery Optimization:
One of the main reasons why your phone stops charging at 85 percent is battery optimization. Many smartphones are equipped with a feature that limits charging capacity to extend battery life. When the battery reaches around 85 percent, the phone automatically stops charging to prevent overcharging, which can degrade the battery’s health over time. This feature commonly exists in newer smartphones and is designed to prolong battery lifespan.

2. Charging Circuitry:
Another reason for your phone stopping charging at 85 percent could be an issue with the charging circuitry. If the charging cable, adapter, or the phone’s charging port is faulty, it can disrupt the charging process, leading to incomplete charging cycles. This can result in your phone displaying 85 percent as the maximum charge level.

3. Software Glitches:
Sometimes, software glitches can cause your phone to stop charging at 85 percent. These glitches can occur due to various reasons, such as outdated software, software bugs, or incompatible third-party apps. In such cases, restarting your phone or updating the software can often resolve the issue.

4. Battery Calibration:
Battery calibration is another factor that can cause your phone to stop charging at 85 percent. Over time, the battery’s capacity can become misaligned with the software’s estimation. This discrepancy can cause the phone to stop charging prematurely. Calibrating the battery can help synchronize the software’s estimation with the actual battery capacity, allowing your phone to charge to 100 percent.

5. Environmental Factors:
Certain environmental factors can also affect the charging process and cause your phone to stop charging at 85 percent. Extreme temperature conditions, such as excessive heat or cold, can interfere with the battery’s ability to charge fully. Additionally, using a low-quality charging cable or adapter can also lead to incomplete charging cycles.


Q: Is it harmful to charge my phone to 100 percent?
A: Charging your phone to 100 percent occasionally is not harmful. However, keeping your phone at 100 percent charge for prolonged periods can degrade the battery’s health over time.

Q: How can I fix the issue of my phone stopping charging at 85 percent?
A: Start by checking the charging cable, adapter, and charging port for any damage or debris. If everything seems fine, try restarting your phone or updating the software. If the problem persists, consider calibrating your battery or contacting the manufacturer for assistance.

Q: Will using a different charging cable or adapter solve the problem?
A: Using a high-quality charging cable and adapter can help ensure a stable and efficient charging process. However, if the issue lies with the phone’s internal circuitry or battery optimization, using a different cable or adapter may not provide a permanent solution.

Q: How often should I calibrate my phone’s battery?
A: It is recommended to calibrate your phone’s battery every few months or whenever you notice a significant discrepancy between the software’s estimation and the actual battery capacity.

In conclusion, your phone stopping charging at 85 percent can be attributed to battery optimization, charging circuitry issues, software glitches, battery calibration discrepancies, or environmental factors. understanding these reasons, you can take appropriate steps to resolve the issue. If the problem persists, it is advisable to seek professional assistance or contact the manufacturer for further guidance.
