battery size, the physical environment, and whether you are using the computer.
Notes: To maximize the life of the battery:
• Use the battery until the charge is depleted and recharge the battery completely before using it. Once the
battery is fully charged, it must discharge to 94% or lower before it will be allowed to recharge again.
• The battery may optimize its full charge capacity based on your usage. After prolonged periods of limited
use, full battery capacity may not be available until you discharge to as low as 20% and recharge
completely. For more information, refer to the power section of the Vantage app.
• Lenovo provides you with an estimate of how much battery life you might expect from your computer
based on the battery life test under specific benchmark. The actual amount of battery life varies
significantly depending on your computer settings, usage, configuration and other factors. To maximize
the battery life, you can lower the display brightness of the computer display or turn off wireless feature
when not in use.
