How to charge iPhone?

users of even the most modern gadgets sometimes blindly follow the rule, which was distributed at the dawn of mobile communications: before using the device must be completely discharged, then completely Charge. The most fanatical users developed this rule to the absurd, offering to fully charge and discharge the iPhone three times. Is there any sense in this - consider in the article.

How to charge an iPhone for the first time: a bit of theory

The practical studies of the problem of charging mobile devices was engaged in someone Eric Limer - experiments led him to unexpected conclusions. To charge an iPhone to 100%, as it turned out, in general harmful - the optimal level of charge should be from 50% to 70%. When charging up to 100%, the iPhone battery is able to withstand only 500 cycles, while when charging up to 70% is more than a thousand.

Where did the prejudice come about the importance of full charge? The first cell phones were equipped with nickel batteries subject to the so-called memory effect. The memory effect lies in the fact that in violation of the operating recommendation, the active substance of the nickel battery is crystallized - as a result, the maximum amount of energy is reduced that the battery can stock. The battery "remembers", which was not completely used, and therefore it gives energy only to a fixed limit - hence the name of the effect.

Modern gadgets are equipped with lithium-ion batteries, which memory effect is not peculiar. Almost everyone who talks about the need to use to discharge the phone completely, belong to the elder generation and started with black and white "reversals" for which this rule was relevant. Now, from the competent consultant in the salon, the buyer will not hear such a recommendation.
