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 signicantly 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.
• Conguring 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 congure 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 congure Dell longevity mode:
1 Right-click the battery icon on the Windows notication area and click or tap Dell Extended Battery Life Options.
The Battery Meter dialog box appears.
