Put aside the
convenience of use aside, just from a technical point of view to talk about the
charger has been plugged laptop battery life impact.
First of all, it needs to make
it clear that, in terms of current technology, the construction of batteries is
basically the same regardless of whether it is an Apple notebook, a Microsoft
notebook or other brands of notebooks. Laptop has been plugged into the
charger, the laptop's battery life is lossy. The reason is very simple, when we
connect the laptop power, although not using the battery power, but the laptop
battery power will gradually drain, but the loss of slower. Here, since we
plugged in the power supply, the laptop automatically recharges until it is
fully charged, when the battery power is slightly reduced. As a result, when we
use the laptop for a long time when the power is on, the battery in the laptop
will be charged and discharged repeatedly according to the above rules. Of
course, this will shorten the life of the notebook
Perhaps, it is out of the above
considerations, there are now some notebook manufacturers in order to extend
the life of notebook batteries, but also to do some work, developed a number of
battery protection software
Open the software, some
software has the battery options, and offers two options: "maximum life
time" and "best battery life." When you choose the longest life
time, and not installed the same software, when connected to the power, the
laptop battery slightly reduced, it will immediately automatically charge.
When choosing the best battery
life, usually, when the laptop battery slightly decreased, it will not let the
battery automatically charge, but let it power down. Wait until the battery
power drops below 55%, the software will automatically cut off the AC power,
the use of battery power laptop power until the battery is fully discharged,
and then re-connected to the laptop for power supply, while using AC Charge the
battery. However, it will not charge the battery, but to 60%. Then repeat the
above action.
Of course, in addition to these
features, some software, there are other roles, such as battery correction.
And, battery status inquiry (this more general, no effect)。
Finally, before using a laptop,
many people may not have used similar software, nor did any special maintenance
on the laptop battery, the battery power fell. For example, the previous full
power to work 3 hours, and now basically only less than 1 hour, so the
maintenance of the laptop battery is not just the usual clean-up, but also
scientifically effective to control, if your laptop battery can not Used, can
only consider to buy a new one.
