Why calibrate the battery?
Over time, batteries in portable devices may show inaccurate charge levels, causing the indicators to not accurately reflect the actual state of charge. Battery calibration helps to adjust the software to detect the actual capacity of the battery, optimizing the accuracy of the indicator and extending the life of the battery.
Steps to calibrate the battery
1. Configure your equipment for the process
- Disables the sleep and power saving options:
- In Windows: Enter Settings > System > Power and sleep > Additional power settings.
- Select the equipment so that it never shuts down or goes to sleep, either on battery or connected to the power supply.
- Deactivate the screen saver: This measure prevents interruptions during the process.
2. Fully charge the battery
- The laptop is connected to the charger and is expected to reach 100% of charge.
- Once charged, leave the laptop plugged in for at least 2 additional hours to make sure it is completely full.
3. Discharge the battery completely
- Disconnect the charger and use the notebook until the battery is completely drained.
- Be sure to perform tasks that require power, such as surfing the Internet, playing videos or using demanding programs.
- Let the laptop automatically shut down when it reaches 0%
4. Leave the laptop off without charging
- Once the notebook is turned off, wait 5 to 6 hours before reconnecting it to the charger. This will enable stabilization.
5. Charge the battery again
- Connect the charger and charge the battery up to 100%, without interrupting the process. Do not turn on the notebook during this initial charge.
Additional tips to extend service life
- Avoid frequent full charges and discharges: Always keep the load level between the 20% and the 80% to reduce wear.
- Disconnect the charger once the 100% is reached: Keeping the charger plugged in can generate unnecessary heat and damage the charger.
- Do not expose the notebook to extreme temperatures: Both heat and cold reduce capacity.
- Use the power saving mode: Reduce screen brightness and close unnecessary applications to consume less power.
- Repeat calibration every 2-3 months: This ensures better performance of the software that manages it.
By following this guide, your battery should show more accurate charge levels and maintain good long-term performance.
