Lithium battery charging expertise on mobile phones

　　Today's smart phones consume a lot of power, and many users charge them several times a day. However, some experts write that a fully charged battery will cause aging.

　　The traditional concept is that a new mobile phone must be charged for more than 12 hours before the first use. In fact, this is how NiMH batteries are used.

　　Some people have the habit of charging their mobile phones before going to bed so that they can be fully charged the next morning, but this is risky because few chargers will not automatically stop charging after the battery is fully charged. It is recommended to stop charging when the battery is almost full to avoid accidents. When the battery is fully charged, still put the battery on the charger, which will cause the maximum charge capacity of the battery to drop slightly, and long-term accumulation will have a great impact.

　　, Some people think that you should wait for the battery before using it. In fact, the charge is not afraid, more afraid of no electricity, because one of the lithium battery managers, it can ensure that the battery is charged normally, if the lithium battery is completely discharged, the storage manager and keep it long Time outage caused the battery to fail to charge. If you do not use batteries for a long time, such as camera batteries, it is recommended that we have more than 40% of the batteries, and the battery will lose about 5% to 10% of the battery every month.

　　Battery life is also closely related to operating temperature. At 0°C, the maximum capacity of the battery drops by 6% per year. Loss increases with increasing operating temperature.

　　The battery life is generally 3-5 years, but because the current mobile phone update speed is too fast, the mobile phone battery is not a wise choice. You can rest assured that the battery life is not reached and you have replaced the new phone.
