How to charge the batteries of smartphones and laptops

The smartphones and laptops are mainly used lithium-ion batteries. There are different opinions about how to charge them. Someone thinks that the device should always be charged at 40-80%, and it needs to be recharged regularly, and someone thinks that we should wait for the full discharge of the battery and then charge it to 100%.

This confusion stems from the fact that before were often used nickel batteries that have attended the "memory effect." Such devices have to discharge to zero. Lithium-ion batteries do not have this problem, but still skrok their life is measured in years, and to maximize the life of their life, you need to know how to properly use them.

1. Recharge the device regularly

Do not allow the device to be discharged to 0%. It is better to regularly recharge it. Below you can see a table depending on the number of charge cycles (battery life) of the depth of discharge. Having considered this table we can see that it is better not lower the charge to 50%, and recharged every time the battery is discharged per cent of 10-20%.

2. Do not leave your device on the charging

Lithium-ion batteries do not require constant charging to 100%. It is better if your device will be charged in the range of 40-80%. So as far as possible keep the charge in this framework. If you charge your device up to 100%, do not leave it plugged in to charge! Lots of people do, but that is what leads to a reduction in battery life. If you set your device to charge at night, use special power-saving outlets that disconnect your charger after a specified number of hours. NB: Normal (not Chinese noneym) laptops and phones have a built-in charge controller and disable own charging reaches 100% - some even report signals the end of charging. Such devices can be kept in a constantly enabled network.

3. Once a month, fully discharge the battery and then charge up to 100%

This statement may seem contradictory, given that we are told in the beginning. But now we will explain everything. Complete charge-discharge cycle once a month is necessary to calibrate the device. On your phone or laptop charging balance is usually stated as a percentage or hours and minutes, after which the device is fully discharged. After a large number of small charges, this function begins to operate properly, and therefore should be made once a month, the device calibration (full discharge-charge cycle), the readings were accurate.

4. Avoid overheating

High temperatures adversely affect the life of your battery life. The following label you can see the dependence of battery loss on the temperature in which it is located. So take care of your device from overheating and do not work with the notebook on your lap. Using these guidelines, you will be able to significantly extend the life of your battery. But do not get too hung up on it. If it so happened that at hand you did not have the charger, then do not worry that your gadget runs down to zero. And there is nothing wrong to charge it completely if you're going on a long journey. Lithium-ion battery still lasts no more than 2-3 years, how would you take care of it or even if your device simply will lie all this time on the shelf. In general, do not overdo it, use the device as you wish. But if you have the opportunity to apply these recommendations, do not neglect them.
