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.
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:
Windows Power Plan
Type of storage, such as a peripheral storage
Let me know how it goes and you have a great day!
