The performance and capacity of laptop batteries have decreased over time. In addition, the way the battery is used daily may interfere with these attributes.
Many factors can promote battery performance:
The battery unit experiences a gradual and irreversible capacity loss in each charge-discharge cycle.
Temperature and discharge can affect battery performance and capacity.
The battery capacity may be reduced even if the computer has been unplugged from the power source and is not being used.
If not used for a long time, the battery will drop below the recommended low voltage level. Discharging the battery below the recommended low voltage level can cause physical damage to the battery and render it unusable.
Note: If the battery cannot be recovered after 30-60 minutes of charging, it is likely to cause physical damage and must be replaced.
Keeping the battery high for a long time in a high-temperature environment will accelerate the loss of capacity and performance. The computer generates heat due to high load or poor ventilation. This temporarily impairs the speed of charging and battery consumption. When the battery is cooled to an acceptable operating temperature, the battery function resumes normal operation.
In order to maintain battery capacity, laptop batteries are designed to discharge a small amount after being fully charged. For most laptop batteries, this behavior is normal. Once the charge level is below 95%, the battery will start charging.
Use high-definition graphics or video processing software to accelerate the loss of capacity and performance. For example, using a 3D game will reduce capacity faster than a word processor.
Laptop configuration and power saving settings can affect battery performance. These settings are:
Screen brightness
Backlit keyboard
Screen Resolution
Windows energy saving combination
Processor speed
Storage type, such as storage device
