For the \"activation\" of lithium batteries, many statements are:
The charging time must be more than 12 hours, and repeatedly do three times of full charge and discharge in order to activate the battery.
This \"the first three charges to charge more than 12 hours\" is for the rechargeable batteries of the 1990s, when the kind of nickel-cadmium batteries have a memory effect and need to be fully filled to ensure the battery capacity. The use of lithium-ion batteries on mobile phones, it has no memory effect, generally 2-3 hours can be filled, full is enough. If the first three charges and discharges of the new battery can really reach 12 hours or more, it will cause great harm to the battery, which may cause the battery to bulge and even burn. Fortunately, both the mobile phone and the charger have protection circuits, which will automatically power off when charged to 100%, and will not continue to charge when plugged into the charger. However, it is better to unplug the charger at this time to prevent the charger protection circuit from overcharging the battery in case of problems, causing serious harm to the battery material and affecting the capacity and life of the battery. Usually, the charging method described in the mobile phone manual is the standard charging method suitable for the mobile phone.
The reasons why the mobile phone cannot be charged:
1, first see if it is the battery problem, you can change a piece of the same battery to see if it is the same problem.
2, conditions allow the mobile phone can remove the battery, with a universal charge to try to see if you can charge into the electricity.
3, if the battery can be charged, then it indicates the problem of the data cable or mobile phone jack. If not, then it's the battery.
4, If there is a problem with the mobile phone jack, try to use a brush or a small brush to wipe the dust inside the interface, which may also be caused by excessive accumulation of dust in the interface.
5, if the wipe is not recommended to change a socket or data line. It is possible that the problem is caused by poor power contact.
6, if the above methods still can not make the mobile phone normally charged, it is recommended to go to the local maintenance point for maintenance.
