Battery full charge capacity is only 88% of its design capacity

[Sid121]

I used HP Support Assistant for this purpose.

What should I do now. Please help me !

@Sid121

I reviewed your post and I understand that the battery full capacity is showing only 88%.

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you update the BIOS from the below link and check if it helps.

If you continue facing the issue, then follow the steps in the below article and calibrate the battery.

Let me know how it goes and you have a great day!

Thank you for the update.

Please let us know once you performed the troubleshooting steps.

Have a nice day!!

I ran the battery check at startup and my battery passed the test/check. Also there was no option for battery calibration. I wanted to know if battery calibration is not required, and also whether my battery has become old (now its full charge capacity is showing only 86% of its design capacity in HP Support Assistant) and thus needs replacement ?

Many factors can contribute to battery performance:

• Battery cells suffer gradual, irreversible capacity loss with each discharge-charge cycle.

• Temperature and discharge loads can impact battery performance and capacity.

• Battery capacity and charge can decrease even when the computer is unplugged from a power source and not in use or turned off. The amount of decrease can vary by computer model. To reduce the charge consumption while the computer is turned off, disconnect any peripherals and disable Wake-On LAN settings in the BIOS.

• During prolonged storage or non-use, the battery charge can decrease below its recommended low-voltage level. Discharging the battery below its recommended low-voltage level may physically damage the battery and result in the battery becoming unusable.

  NOTE:  If the battery does not recover after charging for 30 - 60 minutes, the battery has most likely sustained physical damage and must be replaced.

• Leaving the battery at a high level of charge in a high-temperature environment for extended periods can accelerate the loss of performance and capacity.

• The computer generates excess heat during high workload or if it is not properly ventilated. This temporarily impairs the battery charge and discharge rate. The battery function returns to normal when it cools to an acceptable operating temperature.

• To help maintain battery capacity, HP batteries are designed to discharge a small amount once fully charged. This is normal for most notebook batteries. The battery will begin to recharge once the charge has dropped below 95%.

• Using software for graphics processing or high-definition video accelerates the loss of performance and capacity. For example, playing 3D games decreases capacity faster than using word processing applications.

• Your notebook configuration and power settings can impact your battery performance. This includes settings such as:

  • Display brightness

  • Backlit keyboard

  • Display resolution

  • Windows Power Plan

  • Processor speed

  • Type of storage, such as a peripheral storage

I hope that answers your question.
