Improving battery life

The operating time of a battery, which is the time the battery can hold a charge, varies depending on how you use your laptop computer.

The operating time of your battery signicantly reduces if you use:

• Optical drives

• Wireless communication devices, ExpressCards, media cards, or USB devices.

• High-brightness display settings, 3D screen savers, or other power‑intensive programs like complex 3D graphics applications and

games.

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.

• Conguring 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 congure the battery‑charging behavior to increase the battery life.

Dell longevity mode

Frequently connecting and disconnecting your computer from 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 to

enable longevity mode.

NOTE

: Dell longevity mode may not be supported on all laptops. To congure Dell longevity mode:

1 Right-click the battery icon on the Windows notication area and click or tap Dell Extended Battery Life Options.

The Battery Meter dialog box appears.

2 Click or tap the Longevity mode tab.

3 Click or tap Enable to turn on, or Disable to turn o Dell longevity mode.

4 Click or tap OK.

NOTE

: When longevity mode is enabled, the battery charges only between 88% to 100% of its capacity.

Dell desktop mode

If you primarily use your computer with the power adapter connected, you can enable the desktop mode to moderate the extent to which

your battery is charged. This reduces the number of charge/discharge cycles and improves battery life.

Your Dell laptop automatically monitors the charging and discharging behavior of your battery, and if applicable, displays a message to

enable desktop mode.

NOTE

: Dell desktop mode may not be supported on all computers.

To enable or disable desktop mode:
