— laptop configuration for battery health:
* rapid charge can reduce battery lifespan
* Conservation Mode is “useful to extend the lifespan of your battery when plugged. When this mode is enabled, the battery will only be charged to 55-60%”. In conservation mode, perhpas I can connect my charger all day? Well, I guess it’s good habit to unplug charger once a while.

— depletion .. Contrary to some recommendations, you don’t need to routinely discharge a lithium-ion battery completely and then recharge it to somehow reboot or calibrate it – this is a destructive practice that’s very hard on your battery.  Whether or not it’s a smart idea to perform a complete discharge a couple of times a year remains an unanswered question. There are many types of batteries. I choose to heed the advice from the battery manufacturer.

Almost-depletion .. Generally, the consensus seems to be that letting your battery discharge (without bottoming out — aim for around 20 percent) and then charge it when possible is the best practice.

— overnight .. there was a time when users were advised to refrain from keeping their devices plugged in. Today, however, modern devices are designed to stop charging at 100 percent and thus keeping them plugged in doesn’t impact the battery’s lifespan, according to Battery University.  However, A95 battery became “bloated” due to overnight charging. LED lamp says “avoid overnight” too.

— long term storage (of laptop).. If you’re going to store your laptop for an extended time without using it, then discharge or charge it to 50 percent before putting it away. I think many batteries nowadays are shipped in this condition, and warehoused for months.
