normal use should be when to start charging in our forums, often see this argument, because the number of charging and discharging battery is limited, so it should be possible to run out of phone battery power recharging. But I found one on lithium-ion battery  official beats by dre charge and discharge cycle test table, on the cycle life data is as follows: cycle life (10% DOD):> 1000 cycles life (100% DOD):> 200 times which DOD is the discharge depth abbreviation. Can be seen from the table, number of charge cycles and the depth of discharge, 10% DOD cycle life than when the 100% DOD for much longer. Of course, if the actual charge equivalent to the relative total capacity: 10% * 1000 = 100,100% * 200 = 200, the latter fully charge and discharge, or better than some, but the previous users of that argument do some amendments: Under normal case, you should have reservation in accordance with the remaining battery power runs out and the principle of full charge, but if your battery is expected in the first two days you can not adhere to the time of the day, you should start charging a timely manner, of course, if you are willing to back the charger to the office has a different matter. And you need to charge to meet the anticipated upcoming busy communications will lead to an important event, even though the battery still a lot more than power, then you are simply charged ahead of time because you do not really lost, "a" sub-charge cycle life , that is, "0.x" times only, and often this x will be very small. Remaining battery power runs out and the principle of charging is not want you to go to the extreme. And long charging a very wide spread as saying that "as far as possible the cell phone battery run out, it is best used in automatic shutdown." This practice is just practice on nickel batteries, designed to avoid occurrence of memory effect, unfortunately, it is also spread of lithium batteries on this. It has been because the cell phone battery low warning appears, still do not charge to use the example has been used in automatic shutdown. The results in this example was  monster beats by dr. dre test charging the phone and boot in no response, had to give customer service overhaul. In fact, this is the result of excessive discharge as a result of the battery voltage is too low, so do not have a normal result of the charge and start conditions. 3, the correct way on the lithium battery cell phone sum up, I lithium batteries used in mobile phone charging and discharging, the most important tips are: 1, in accordance with the  beats by dre computer standards and procedures, charging time,  nike beats by dre even the first three have to do so; 2 , when there is low cell phone battery tips, you should start charging as much as possible in a timely manner; 3, lithium batteries do not require special methods of activation, normal cell phone use in lithium batteries would be natural activation. If you insist to use wisdom of "the three previous 12-hour long activation charge" approach, in fact, there will not be effective. Therefore, all 12 hours long pursuit of the lithium battery cell phone charger and practices used in automatic shutdown, are wrong. If you used to be done in accordance  beats by dr dre shop with an error saying, please correct them in time, perhaps not too late. Of course, cell phones and chargers to protect themselves and control circuit of good quality cases, the protection of lithium batteries is quite assured. Therefore, the charge is the key to understand the rules, in some cases also may make some concessions. For example, you find that the phone must be charged before you go to bed at night,  beats by dre uk sale you can also start charging before going to bed. The key is, you should know what the right thing, and do not do it deliberately in accordance with the erroneous statement.Laptop battery
