Why Is My Phone Not Charging Past 85


Why Is My Phone Not Charging Past 85?

We rely heavily on our smartphones for communication, entertainment, and productivity. So, when our phone battery refuses to charge past a certain percentage, it can be frustrating and worrisome. One common issue users face is their phone not charging past 85%. In this article, we will explore the reasons behind this problem and provide possible solutions.

1. Battery Optimization Settings:
Many smartphones nowadays have built-in battery optimization settings to extend battery life. These settings often limit the charging capacity to 85% to prevent overcharging. Over time, this can help maintain the overall health and lifespan of the battery. If your phone is not charging past 85%, check your battery optimization settings to see if it is enabled.

2. Software Updates:
Software updates are designed to improve the performance and functionality of your phone. In some cases, these updates may include changes to battery management, which can affect the charging behavior. If your phone recently underwent a software update and started stopping at 85%, it is possible that the update has introduced a new charging algorithm. Check for any available software updates and install them to see if it resolves the issue.

3. Battery Calibration:
Battery calibration is a process that ensures your phone accurately displays the battery percentage. Over time, the battery calibration may become inaccurate, causing your phone to stop charging at a certain percentage, such as 85%. To calibrate your battery, completely drain it until your phone shuts off, then charge it to 100% without interruption. This process can help recalibrate the battery indicator and potentially resolve the issue.

4. Faulty Charger or Cable:
Sometimes, the problem lies with the charging accessories rather than the phone itself. Faulty chargers or cables can hinder the charging process, causing your phone to stop charging prematurely. Try using a different charger or cable to see if the issue persists. Additionally, ensure that the charging port on your phone is clean and free from debris, as it can also prevent proper charging.

5. Battery Degradation:
Phone batteries degrade over time due to chemical reactions occurring within them. As a result, their capacity to hold a charge diminishes. If your phone is older or has been heavily used, it is possible that the battery has degraded to the point where it cannot charge beyond 85%. In this case, you may need to replace the battery to restore full charging capacity.


Q: Can I disable battery optimization settings to charge my phone beyond 85%?
A: While it is possible to disable battery optimization settings on some phones, it is not recommended. These settings are in place to protect the battery’s health and prolong its lifespan. Disabling them may result in faster battery degradation and shorter battery life.

Q: Will recalibrating the battery fix the issue permanently?
A: Recalibrating the battery can help resolve charging issues related to inaccurate battery percentage readings. However, if the problem is caused by other factors, such as battery degradation or software updates, recalibrating alone may not provide a permanent solution.

Q: How long does a phone battery typically last?
A: The lifespan of a phone battery can vary depending on usage patterns, charging habits, and the phone model. On average, a phone battery can last between 2-3 years before its capacity significantly degrades.

Q: Should I replace the battery myself or visit a professional?
A: It is recommended to visit a professional service center or authorized technician to replace the battery. They have the necessary tools and expertise to ensure a safe and proper battery replacement.

In conclusion, a phone not charging past 85% can be attributed to various factors such as battery optimization settings, software updates, battery calibration, faulty accessories, or battery degradation. understanding the potential causes and trying the suggested solutions, you can troubleshoot the issue and restore your phone’s full charging capacity.
