Dell laptop battery Desktop and Longevity mode?

Question

I have an Inspiron 17r Special Edition and I mainly have it plugged in and it rarely leaves my desk. I have enabled both modes, does this matter? Am I correct in saying that desktop mode is good to have enabled if you keep it plugged in? Could someone please explain the two and which one is better for leaving it plugged in all day :) Thanks

Hi NickFFE,



The Dell Desktop Mode feature enables you to protect your laptop battery health. Continuously powering your computer by connecting it to an A/C power outlet may reduce the battery life. The desktop mode feature protects the battery health by moderating the extent to which your battery charges, protecting your battery when it is not in use.



Note: When desktop mode is enabled, the battery will only charge between 50 and 100 percent of its capacity.



The Dell longevity mode feature enables you to protect your laptop battery health. 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.



Note: When longevity mode is enabled, the battery charges only between 88 percent and 100 percent of its capacity.



You can enable both Desktop and Longevity mode. If you want to keep the system plugged in, I would suggest to enable Desktop mode on your computer.



Hope this helps.



Thanks and Regards,
