Survey Results: Most students said, unnecessary as the first view is used to automatically shut down and then charge, not like the second view, it is free of charge. Are generally used when the battery needs charging again when the computer prompted the charge, of course, prompts the time can be set, the default is to 3%.
Proposed method: the method I recommend most of the students with the method is the same. In fact, whether laptop uses lithium or nickel-metal hydride batteries, these batteries are a memory effect, Ni-MH battery with memory effect is very obvious, but the lithium will have the same memory effect, but its memory effect smaller than nickel-metal hydride Bale . No memory effect on lithium argument, but exaggerated irresponsible business conduct in advertising, is totally misleading. Well, since the battery has memory effect, it should be noted when charging point, try to run out of charge, but do not have to deliberately say must use the computer to Battery laptop battery automatically shut down, so there is no harm with it though (because the laptop battery has a charge and discharge secure, automatic shutdown laptop battery has not yet reached the standard discharge protection), but you feel so tired? In fact, this way less than 3% charge on the good, the memory effect will certainly be, compared to natural wear and tear, it should be nothing. As to the second point of view to charge to charge, the author is completely disagree, have already said, whether laptop batteries or lithium nickel-metal hydride, which has a memory effect, so if the battery life in this way will be greatly reduced.
