It is recommended to use the laptop at a temperature lower than 90 degrees Fahrenheit.

No Proper Charging and Discharging

Laptop battery will stop charging after it reaches 100% even if you have connected it to power. It will not affect the battery life since the internal circuit will stop the power flow once it reached full capacity.

Do not use the laptop until it shuts down. Make sure to charge it before it reaches 10%.

Battery become Old

There are many factors that affect the battery life. Some of them are number of applications used at a time, how often you use it, etc. The important factor is its age.

Compared to a new battery, old battery drains fast and you need to replace it. The laptop battery will last about 3 to 4 years on an average.
