Way 3: Unplug at Full Battery

Step 1: Let the battery charge to 100% then simply unplug the laptop.

Step 2: When it gets close to dying, or the left power is less than 5%, go ahead and plug it in and let it charge up.

The last option is to let the battery charge to 100% and then simply unplug the computer. When it gets close to dying, go ahead and plug it in and let it charge up. However, this could reduce battery life on newer ion batteries, so for those batteries, it’s suggested you only let the battery power drop to 35% to 45% and then charge it back up to 75% to 85%. This apparently will give you the best battery life because it won’t constantly run into charge and recharge cycles. So we recommend you follow the last one to restore your laptop battery.
