Whether your iPhone will kill the habit of leaving it on charge overnight

«IPhone can not be left to charge overnight" - unscientific myth. Ostensibly it affects the life of the battery and may damage the unit - up to fire or explosion. It's time to dispel this misconception.

For those who know the answer to the question posed in the title, and opened this article, just to make sure, I will say at once: Charging your iPhone throughout the night did not harm its battery. If you're wondering why, read on.

In fact, everything is very simple. The bottom line is that if they wanted to, you will not be able to charge the battery more than foreseen by the manufacturer. The iPhone, as well as in any other modern gadget used lithium-ion and lithium-polymer batteries, which have a controller that disables the charging when the 100% charge.

In other words, when your iPhone is fully charged, it will switch to an external power source (that is to say the network adapter) and will run away from him.

The same applies to the charging is not fully discharged smartphone. It does not in any way harm the battery and even preferred. And here's the thing here.

As you may know, lithium batteries have a limited number of charge cycles (the iPhone around 500), but the term "cycle" refers only to the complete charge cycleWhen the battery is charged from 0 to 100%. If you charge the iPhone with 90 percent to 100, using only 1/10 of the cycle. Ie from 90 to 100% battery can be recharged without loss of capacity is not 500, but 5000 times!

That said, there is no sense consciously iPhone battery discharge to zero, rather than put it to charge when it is needed. If you do, then needlessly expend one full charge cycle.

Of course, if you really use your smartphone while it is not completely discharged, then there is nothing wrong, but to do so specifically - is just silly.

Most people are worried about their iPhone batteries more than you need. Most often, this concern is based on the knowledge of the older nickel-cadmium batteries that had real problem - the so-called "memory effect", when the battery capacity is decreased after an incomplete cycle charge. But this phenomenon has absolutely nothing to do with lithium batteries.

Therefore, charge and use your iPhone as you are comfortable - it in no way will not damage the battery.
