Is this true? My laptop has been on 100% of the time (although usually asleep) and also plugged in much of the time since I bought it in 2014.

- mschuster91 4y agoBattery vendors generally recommend you do not keep them on a charger all the time since the charger will keep it at 100% charge, and the longer a battery is at 100% charge, the more degradation it will experience for electro-chemical reasons. Sooner or later, that can lead to battery swelling and eventually a catastrophic thermal runoff. Additionally, keeping a laptop shut and running usually messes with its thermal design as the heat can't escape to the top via the keyboard, further heating up the battery.
- windowsrookie 4y agoMost laptops in the last few years have an option to not fully charge the battery if it's going to sit plugged in. I know this option is available on Dell, Asus, and Apple laptops. I assume others have it as well.
- icoder 4y agoI doubt it, as I n++ your n=1 by experience, but also since I think it shouldn't be hard, electronics wise, to stop charging once full (or even, optionally, 80% / 90%) and fully run on AC as long as it's available. Also I'd say this is an apparent user requirement for laptops.
