If you primarily use your computer with the AC adapter attached and only infrequently use battery power, battery deterioration may occur faster when the battery is constantly charged at 100%. Lower the charge thresholds of your battery if you use your Lenovo computer often while on AC power.
If you primarily use your computer with the AC adapter attached and only infrequently use battery power, battery deterioration may occur faster if the battery is constantly charged at 100%. Lowering the charge thresholds for your battery, periodically resetting the battery gauge, using Maximum Lifespan mode, or using Battery Health Mode will help increase its lifespan.
To change the battery charge mode, click the Battery Maintenance... button on the Battery Information tab. On the Lenovo computer with replaceable battery, there are three options listed below the Charge mode section. By default, Automatically optimize for battery lifespan is selected. This option sets the battery charge mode automatically by monitoring battery usage. Initial mode is Maximum Runtime mode and this option charges with full charge voltage. When the battery charge mode is set Maximum Lifespan mode, it helps to increase battery lifespan by reducing charging capacity. When Maximum Lifespan mode is set, Power Manager’s battery gauge displayed on taskbar is shown with green outline. Always fully charge (Start when below 96%; stop at 100%) uses Maximum Runtime mode. This mode starts charging when the remaining capacity of the battery is below 96% and stops charging at 100%. Note, this setting may not help to increase battery lifespan. You can also create your own stop and start thresholds by selecting Custom charge threshold and entering your preferred values.
On the Lenovo computer with embedded battery, there are also three options listed below the Charge mode selection. By default, Always fully charge (Start when below 96%; stop at 100%) is selected. If battery stays at or near full charge, it is recommended you select Optimize for battery health to set Battery Health Mode. Battery Health Mode immediately discharge your battery to 50% and set to stop charging at 50% and start charging at 46%. You can also create your own stop and start thresholds by selecting Custom charge threshold and entering your preferred values.
. I am worried now that keeping my lap on charging only whole night might hit battery life. So is there any kind of application/software/workaround where my laptop discharges to a defined level (even while connected to power source) and takes up charging automatically ?
