How long does it take to charge a new mobile phone for the first time? Some people have said that the first three times of the new mobile phone will be charged for 12 hours. In fact, it is not needed now, currently, cell phones use lithium batteries without the so-called battery memory, so we don't need to fill up for 12 hours. We just need to charge when the battery is not powered. If the battery is full, it's OK, in the future, when will it be convenient to charge and when to plug in the charger. The general situation is that when the cell phone battery is less than 20%, it can be charged until it is full.
Most of the current cell phone battery is lithium battery. The manufacturer has done corresponding processing on the lithium battery when the lithium battery leaves the factory. Therefore, the so-called charging and activation are not required when the lithium battery is used, it is "pay-as-you-go ".
Do lithium batteries need to be charged after discharge? The answer is No. Many people may be affected by the usage habits of NiMH batteries. In fact, lithium batteries do not have the memory effect, so they do not need to be charged after discharge.
