About batteries and charging your laptop....

921 Views 2 Replies 3 Participants Last post by  john61ct
every time my laptop battery nears 20%, i charge my laptop all the way to 100%. once it's fully charged, i usually need to use my laptop for a couple of hours more so i just leave it plugged in then when i'm done, i turn off my laptop then unplug it. later during the day, when i need to use it again, i plug it first then turn it back on so it stays at 100% for the rest of the day. i do this because if i follow the popular tip 'leave it at 20 - 80,' i'd be recharging my laptop multiple times during the day and i don't know if that's more harmful to the battery than what i do. anyone knowledgeable about this who can help me?

Unplugging at 80% would be slightly easier on the battery, but less convenient for you. I would just keep doing what you're doing, and buy a new laptop battery (about $60 for my old machine) should it come to that.
The SoC% your computer shows you

is on the scale from 0% - 100% that the engineers defined, not based on the data sheet specs from the cell maker.

So maybe not 20% - 80% but certainly shooting for good battery longevity rather than maximizing every mAh scrap of capacity utilization.

That said, keeping your cycling around the 50% mark will give you many times more cycling lifespan

than going all the way from top to bottom.

Staying between 40% and 60% might last for a decade.

But too much trouble, replacing the battery is cheap and easy.
