In fact, every laptop user at least once asked questions about how long you can keep the laptop on charge, and whether to remove the charger plug from the connector when the battery is fully charged. The opinions of users on the Internet on this topic were usually divided, and in the open spaces of the network among laptop users, serious debate broke out about the features of laptop batteries. This article is intended to dot the "i" in the above question.
Is it always necessary to keep the laptop on charge?
If you look for the answer to this question on thematic forums, you can find that there are only three main opinions on this subject:
- A permanently connected charger does not affect the operation of the laptop and battery life
- Constant recharging can lead to overheating of the device and premature battery failure
- It is best to remove the battery pack from the device altogether and insert it only if necessary, mainly using a laptop as a desktop computer
Reference! These tips were really relevant for the batteries of the last generation, but now their use is unlikely to be justified.
In most modern mobile technology, the so-called lithium-ion batteries are used, which are characterized by an extended service life and a low level of self-discharge. Such batteries are disconnected from recharging when they accumulate the maximum possible amount of energy, and resume charging when the charge drops below a predetermined level.
However, lithium-ion batteries are still not perfect, and have their drawbacks. For example, they gradually lose in energy intensity after each recharge cycle. Over a long period of time, this significantly affects the state of the battery, so over time, many owners of modern mobile equipment begin to notice that their device ceases to “hold” the charge.
Advice! In order to extend the life of such a battery, some experts advise to charge it completely (before shutting down) about once a month, and at other times to charge it periodically.
How to properly charge a laptop: recommendations
Not many laptop users know that most of their models have a so-called energy-saving mode, which allows you to extend the battery life. This mode, however, has a significant drawback: a special controller, when it is turned on, does not allow the battery to work at full capacity, and limits the maximum possible charge by about 80%.
If we are talking about buying a new laptop, it is recommended to charge it “one hundred percent” before the first power-up, that is, wait until the battery is fully charged, even if it takes a lot of time. In addition, after the first power-up, it is recommended that the battery be fully discharged and charged three times, without leaving the battery discharged for a long time. Moreover, in the "discharge" / charge cycles, it is recommended to give the laptop an average load level, that is, do not play "heavy" video games and do not watch full-length films from external media.
It will not be superfluous to also study the technical documentation with which the developer completed his product. Often, it contains general information about the nuances of setting energy consumption "for yourself", which allows the user to select the optimal load and maximum charge parameters for the device.
Reference! Experts do not recommend leaving the laptop discharged for a long time. Moreover, the concept of "discharged" includes not only a completely dead battery, but also a battery with a charge level of less than 10%.
It is also worth avoiding the long idle time of the laptop when it is turned off, fully charged and with a charger connected to it. It is also not recommended to keep the laptop in sleep mode for a long time, since such a mode, contrary to popular belief, still consumes electricity, and very quickly. In order to slightly reduce the rate of battery discharge, you can not only select the energy-saving mode, thereby reducing system performance, but also reduce the brightness of the display through system settings.
