Modern life cannot be imagined without numerous portable devices, be they smartphones, tablets, or laptops, which can only work offline for a while, which depends entirely on the capacity of the battery. The overwhelming majority of people connect their devices to the charger every evening in order to get the maximum supply of energy in the morning for a productive and long day. But only a few know the basic rules for working with a battery so that it does not fail as long as possible.

Battery Charging Guidelines

  1. You cannot discharge the device to 0%.

There is a myth that if a mobile device is driven to a complete depletion of energy each time, the battery will last much longer. In fact, experts advise doing exactly the opposite and plugging your device into an outlet already at a 30% battery level.

The fact is that the myth was born at a time when nickel batteries were inserted into the devices, which had a kind of “memory effect” consisting in memorizing the level of the last charge of energy and no longer contained a larger amount. With the advent of a new generation of lithium-ion energy storage devices, the inconvenience has been eliminated and now the battery life is measured in cycles from full battery charge to 0%, so each time it is completely discharged, their number is reduced.

  1. A full charge is bad too.

It seems that if it is undesirable to completely discharge the battery, it should be kept constantly at 100%, but this is also a myth. The optimum charger reading is 30% -80%. There is nothing wrong with the overall energy level of a device unless it becomes a bad habit. This approach also increases the cushioning of the battery, resulting in shorter battery life.

  1. Mandatory battery calibration.Battery Charging Guidelines

Calibrating the battery of a mobile device or laptop is necessary so that the meter built into the device itself and showing the battery level does not go astray. The procedure completely contradicts the two previous points, but nevertheless, for its implementation, it is necessary to completely discharge the battery and then charge it to 100%. The procedure is repeated every 2 months on average.

  1. The negative effect of overheating.

Long-term use of a mobile device or laptop leads to its overheating, which generally negatively affects the service life of the device, including the battery, which spends more energy on servicing the device.

  1. Use only certified chargers.

It is very important not to overuse the use of unsuitable chargers during the replenishment process. In this case, the risk of battery failure increases. All manufacturers recommend using only certified wires that come with the kit or purchasing identical ones in case of a necessary replacement.Battery Charging Guidelines

  1. Charge the gadget halfway if it will later lie idle.

There are situations when the user does not plan to use any of his devices for a long time, for instance if they are heading home soon or dipping in and out of online casinos for USA players. In this case, it is necessary to properly prepare it for downtime so that in the future there will be no problems with the battery. To do this, experts advise to charge the device by 50% and turn it off for all the time that it is not needed.
