the performance of the original battery is slightly different, some of the original battery will be charged with a higher charge ratio than other original battery, and the battery will aging in advance. As long as the performance of a source battery in connection decreases,
How long is the battery life of the Apple phone First, battery life: According to official parameters, in IPhone5, for example, full charge (20% charge to 100%) 400 times after the battery performance will be reduced by 80%, each year with 20% performance decline. The iphone battery life theory time is about 2-3
Lithium-ion battery use, note three points: 1, how to charge for a new battery in the use of lithium batteries should be noted that the battery has been put into hibernation after a period of time, when the capacity is below normal, the use of time also shortened. But the lithium battery is easy to activate, as long as

much longer than that of 100% DOD. Of course, if it is equivalent to the actual total charge capacity: 10% * 1000 = 100,100% * 200 = 200, it is better to fully charge and discharge the latter. However, the life of a lithium battery is mainly reflected in the charging and discharging cycle. This cycle is an absolute concept. The last time 30% of the power was used, the power was fully charged, and the next time 70% of the power was used, the power wa
The main differences are seven points:1, the composition of the material is different: lithium batteries with carbon materials (graphite) as the cathode, lithium-containing compounds as the positive electrode, nickel-cadmium battery cathode from the nickel oxide powder and graphite powder and other active substances, the anode is composed of cadmium oxide powder and the active substance of iron oxide powder. 2, the working principle is different: the
