How is the iPhone battery more durable? These two taboo can not commit

People accustomed to using the iPhone, often found in the battery after 1 year, began to appear more and more short storage time, or even half a day with no electricity on the situation, and everyone may use the way and habits. In the end how to use to extend battery life?
First of all, users need to know is the iPhone battery "charging cycle" is limited, each battery from 100% to 0% is a cycle, when you use more than 400 cycles, the battery capacity will be reduced by about 20%. To avoid the following two ways to use, you can more effectively maintain power:
1. Use 0% of electricity: iPhone battery is cyclical, if you are fully charged after each time, are used 0%, which is actually a great consumption of the battery. So long-term use of this, it is likely to let the battery into the "deep discharge state", will lose part of the storage capacity.
2. Too full: Many people are used to charge before going to bed, get up in the morning there is 100% power. But in fact, in the middle of the night, iPhone has already fully charged, after the phone all over the night in the overcharge. Then the battery will release a little power and then charge back, has been repeated. The process of long-term down, will make power reduction.

So the best power should be maintained at 40% - 80%, because it will not be counted as a complete cycle, your battery life can be extended. But still let the battery every month from 100% to 0%, so that the battery is completely discharged, you can make the battery re-calibration, to maintain the highest efficiency.
