· Cell phone battery is not fully charged, useless on charge, affect battery life?
Unplug the phone battery is not
fully discharged, the battery will run out of charge will affect the battery
life or capacity?
·
First of all, a direct answer
to the question:
·
• Unplug the phone battery and unplug it before use, without
affecting the battery life. However, if the conditions permit and not too
troublesome, even with the charging cable will be more conducive to the use of
battery life.
·
• The battery is charged when it runs out, which is good for battery
life. On the contrary, if every time the battery power is used very low, or
even light, a great harm to battery life.
·
·
There are many mechanisms for
the decline of lithium-ion batteries, which can be divided into two categories:
abuse and decline. Abuse of recession can be avoided, including overcharge,
over discharge, low temperature, high-power charge and discharge, and so on.
For the phone's use of the scene:
·
• Overcharge: This is not the case with electronic devices that have
circuit protection, so users do not have to worry about it.
·
• Excessive: This is a vague concept. In general, try not to use the
phone below 20%, especially not below 5%, irreversible damage to the battery.
·
• Low temperature: Mainly refers to the low temperature charging is
harmful. Electronic devices are generally protected (the iPad is not charged at
low temperatures), so users do not have to worry.
High-power charge and
discharge: the discharge of electronic equipment, generally more moderate. Is
always playing games, cell phones can hold a three or four hours, which is up
to 0.2C discharge, very gentle, users do not have to worry about. Charge it,
but also by the charger and electronic equipment circuit protection, users do
not have to worry about.•The normal recession is unavoidable. The main influencing factors are the integral of discharge depth and the state of charge at rest.
·
Depth of discharge integration:
also known as the number of discharge cycles, such as from 100% to 50%, which
is even 0.5 cycles. This means that the more you usually use, the faster you
decline. But the phone is used to buy it, can use it.
·
· •State of charge while standing:
This is an academic challenge. The mainstream view is that the higher the
charge, the faster the recession. What this means is that 100% of the battery
is put in a month, and the battery with 50% of the battery lasts a month, the
former's capacity declines more.
·
·
Therefore, what is the
recommended usage? as follows:
·
• First, avoid abuse. Remove the part of the circuit protection,
users need to be careful, try not to use the phone power is very low - carry
charge treasure it.
·
• Second, reduce the decline during normal use. Of course, the time
is still used, you can not play the phone in order to protect the battery,
right? Here's advice is: nothing will put the charging line plugged into the
phone to charge. In this case, the phone will take power from the outside,
equivalent to reducing the number of discharge cycles.
·
• Finally, the "best" way to get used to it is to maintain
the phone's battery charge at 30% -50% of its low battery level until it
reaches 100% two hours before leaving. This reduces "stand-by time in high
battery condition." - Of course, this strategy is not applicable to
consumer electronics such as cell phones, which is disproportionate to the
cost. But for electric vehicles, the battery is very expensive, it is worth
developing such a smart charger. In fact, many agencies are doing.
Q & A summed up the 3 questions
of my friends based on the comments:
1. Apple or book or experts say the
battery should be refreshed from time to time to be full, to be able to
maintain the life ah! ?
A: Apple or book or experts should
say that the previous generation of rechargeable batteries, nickel-metal
hydride batteries, memory effect. The lithium-ion battery, no matter in theory
or in practice, has never observed any memory effect. Therefore, the apple
store or book, or experts such instructions, there is no basis.
2. plug in the charging cable to
play the phone, it is not while charging, while discharging, the loss of the
battery more?
A: The friend who raised this issue
is imagining the battery as a "reservoir" model. Reservoir imports,
exports, it is possible to import water, and exports in the water. Under this
model, it is possible that the water level will not change (the electricity
level will not change), but the actual flow rate will be very big. The
attenuation of battery life is related to the flow is not fast decay fast? The
problem with this idea is that the battery is not a reservoir, it has no two
ports, only one port: this port is either charged or discharged, and no
charge-discharge occurs at the same time.
3. Plug in the charging cable to
play the phone, it explodes?
A: There should be a case of an
explosion in a video game player, but I can not tell which ones are true news
and which ones are fake news. For example, NetEase mobile channel, if Apple
does not renew Apple cell phone explosion will occur, Samsung will not renew
the phone Samsung cell phone explosion news ... ...
Try to analyze, while playing the
phone while charging, will charge the heat (derived from the battery internal
resistance, the power comes from the charging line) and the electric heating
(from the CPU and screen, the power comes from the charging line) of the two
Simultaneous heating effects can cause higher temperatures, potentially risking
an explosion (if battery quality is not acceptable).
After all, the explosion is a
battery safety issue, not a phone battery life issue
