It\u2019s a good trade if you\u2019re plugged in most of the day.<\/p>\n<h3>Do BIOS settings survive Windows reinstalls?<\/h3>\n<p>Yes. BIOS\/UEFI battery settings are independent of the OS. App-set values generally write to the same controller and also persist.<\/p>\n<h3>Is Windows \u201cBattery saver\u201d the same as a charge cap?<\/h3>\n<p>No. Battery saver reduces performance\/background activity to extend runtime; it doesn\u2019t limit how high the battery charges.
