Dell Longevity Mode - Dell Inspiron 20-3045 User Manual

You can improve the battery performance by:
• Operating the computer on AC power when possible. Battery life
reduces with the number of times the battery is discharged and
recharged.
• Configuring the power management settings using Microsoft Windows
Power Options to optimize your computer's power usage
(see "Power Management").
• Enabling the Sleep/Standby and Hibernation features of your computer.
NOTE: The life of the battery decreases over time depending on how
often the battery is used and the conditions under which it is used.
You can configure the battery-charging behavior to increase the battery life.

Dell Longevity Mode

Frequently connecting and disconnecting your computer to a power source
without allowing the battery to fully discharge may reduce battery life.
The longevity mode feature protects the battery health by moderating
the extent to which your battery charges, and prevents your battery from
frequent charge and discharge cycles.
Your Dell laptop automatically monitors the charging and discharging
behavior of your battery, and if applicable, displays a message requesting
you to enable longevity mode.
NOTE: Dell longevity mode may not be supported on all laptops.
To configure Dell longevity mode:
1. Right-click the battery icon on the Windows notification area and click
Dell Extended Battery Life Options.
The Battery Meter dialog box appears.
2. Click the Longevity mode tab.
3. Click Enable to turn on, or Disable to turn off Dell longevity mode.
4. Click OK.
NOTE: When longevity mode is enabled, the battery charges only
between 88% – 100% of its capacity.
