As smartphones and laptops are mainly used lithium-ion batteries. There are different opinions about how to properly 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 earlier were often used nickel batteries, which was attended by "memory effect". Such devices are needed 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, it is necessary 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) on the depth of discharge. Having considered this table we can see that it is better not to give even charge up to 50% and recharge whenever the battery is discharged per cent of 10-20%.
2. Do not leave the unit on charge
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 the device up to 100%, do not leave it connected to the charging! Lots of people do, but that's what leads to a reduction in battery life. If you set your device to charge at night, use the special energy-saving outlets that your charger is turned off after a specified number of hours.
NB: Normal (not Chinese noneym) laptops and phones have a built-in charge controller and charge itself off after reaching 100% - some even report the completion of the charging signal. Such devices can be enabled in order to keep the network constantly.
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 have to explain everything. Full cycle charge-discharge once a month is needed to calibrate the device. On your phone or laptop residue charge is usually specified as a percentage or hours and minutes, after which the device is completely discharged. After a large number of small charges, this function begins to work properly, and therefore should be performed once a month calibration device (full cycle charge-discharge) to testify were accurate.
4. Do not allow the unit to overheat
High temperatures adversely affect the life of your battery. The following label you can see the dependence of the loss of battery power on the temperature in which it was located. So take care of their devices from overheating and do not work with a laptop 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 are going on a long road. Li-ion battery still lasts no more than 2-3 years, how would you take care of him or even if your device simply will lie all the 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.
