This question applies to laptops, but also to smartphones or anything that's battery based and rechargeable.
Does depleting it completely (Computer won't even turn on, or turn on but shuts down immediately) do damage to it? (Both the device and the battery)
Does it shorten the battery's lifespan?
2I think the term is "discharging", thanks. – Madara's Ghost – 2013-02-12T10:27:14.820
1What will cause a problem is if you discharge it to the point it will no longer turn on and then leave it for a long period of time without charging it. – David Schwartz – 2013-02-12T10:49:18.090
1That's true. A battery loses power even if it's not plugged in. Not charging it for a long time gets any battery into that harmful state of low charge. Thanks for pointing that out @DavidSchwartz – André Stannek – 2013-02-12T10:51:35.637
