Correct use gadgets: myths about batteries

The process of charging smartphones, music players and other mobile devices overgrown mass conventions. Try to understand that this is true, and that - fiction. And also to find out how to charge the battery of the device properly.

You can not use non-original chargers

Controversial issue, which is not always possible to give a definite answer. On the one hand, it makes no difference what the charger used - brand or no-name. Modern chargers do not use transformers are used instead of PWM controllers - chips that convert AC power to DC short pulses. Therefore, the risk of serious heat and malfunction is minimal.

Charging gadget manages a special chip, which establishes consumption from the mains current. So burn the wrong charger favorite toy will not work. But to extend the charging process for a few hours or no charge is quite possible, if the charger is not able to give the required amperage.

We must not forget that the gadgets are not regulated supply voltage from the charger, so can not be used Charges with a non-required voltage (for most tablets and smartphones is a USB-ports Voltage - 5 IN). Low voltage will not turn on the chip that controls the charging. High - burn the chip, it is necessary to take in for repair (if low-quality design can burn something else, and the device will go to a landfill).

But if all the necessary parameters coincide with the characteristics of the original charger - why not save? Margins on branded accessories reach 1000%!

Do not use the device in the charging time

Again, double-edged sword. Any gadget headlights on reminder when charging consumes. However, if you play on a smartphone or tablet in the "heavy" games (for example, in the same Asphalt) in the time while the battery charging device, two different processes can lead to unpleasant effects.

On charging gadgets have become hot property. Similarly - during intensive operation (for any resource-processes). In fact, the heating will be added together, and you can overheat the device.

In addition, if you use a smartphone or tablet charging, the battery recharge time will increase. But all this does not mean that the charging device can not be used.

Charge only need a completely discharged battery

This myth born when all devices used accumulators NiMH (Nickel Metal Hydride) and NiCd (nickel-cadmium). Such rechargeable elements have a memory effect. Therefore, if the battery charge when such incomplete discharge, with time their capacitance decreases.

Today, most devices used lithium-polymer (Li-Pol) batteries. Unlike the NiCd battery discharge process is controlled by a microchip. Due to this, when the battery is low, they still give the rated current of the same voltage and current, and that when fully charged.

However, for every chip you need food. Therefore, lithium-polymer batteries are not being charged in the absence of charge. Replenish their energy is desirable in reducing the charge level of 20-30%. Otherwise, the charging process will not start and will have to use alternative modes of charging, and the charge despite the battery circuitry. And this may well affect the cell's life.

Sometimes a full charge is necessary to calibrate the sensor charge, but do not do it too often. And it is not necessary to bring the device to turn off.

Additionally, each battery has a limited service life, expressed in the number of full charge-discharge cycles.

You can not leave gadgets on charge overnight

Another myth associated with the nickel battery. These are quite capable to recharge, resulting in combustion. But lithium polymer stop current consumption when the chip that controls the battery indicates a full charge. So that modern smartphones can be left in charge at any time (unless, of course, they are OK).

Free memory helps save battery

This is really a myth. RAM does not use so much energy. In addition, most of it is made in the form of a single chip, and therefore, the same used at all times when the device is turned on, no matter how many applications running.

Really save battery power allows the processor at lower frequencies. Unfortunately, not all applications are able to operate efficiently in the background and constantly spend energy to the battery. Some applications are in conflict, because of which power consumption increases. Therefore it is best not to wipe with a variety of management and use Task Manager and carry out fine-tuning the system to turn off unnecessary resource-intensive applications.

You need to disable the communication protocols to maximize battery life

This is relatively true. But, contrary to the traditional view, most energy consumption is not Wi-Fi, GPS and Bluetooth, and the usual cellular communications. The use of 3G (and even more so to 4G) reduces the lifetime of the device is significantly faster than the cellular communications and GPRS.

All of these protocols are consuming the most energy at the time of connection. Accordingly, in poor communication conditions (poor reception, the presence of noise sources) the greatest power consumption.

All other interfaces consume little. However, this only applies to modern protocols. We must remember that Bluetooth always working on the most low and simple protocol: the power consumption will be high when connecting the old sets, even if the main modern gadget.
