- How to charge the new mobile phone battery? How long does it take to charge the battery for the first time?
Many friends asked Janon "How to charge the new mobile phone battery? How long does it take to charge the battery for the first time?", so Janon summarized the relevant knowledge about the first charging of the new mobile phone battery and now share it with you.
Regarding the issue of "activation" of mobile phone batteries, many claims are: the first three charging times must exceed 12 hours in order to activate the battery. This statement is misled by the previous nickel-metal hydride batteries. The mobile phone has been activated and aging before leaving the factory. The user does not need to activate it during use, and do not charge for a 12-hour long time. It is the most standard to charge according to the charging method described in the mobile phone manual.
In addition, lithium battery mobile phones or chargers will automatically stop charging after the battery is fully charged, and there is no so-called "trickle" charging that lasts for more than 10 hours in nickel battery chargers. In other words, if your lithium battery is fully charged, it is also white charged on the charger. And none of us can guarantee that the characteristics of the battery's charging and discharging protection circuit will never change and the quality will be foolproof, so your battery will be on the verge of danger for a long time.
The new battery is used for the first three times until the low battery alarm is used, and then it is charged to full with the original direct charge when the phone is turned on, and then continues to charge for about 1 hour.
In daily use, the battery should be fully charged. To avoid charging for a long time, it is recommended to use the alarm. In case of shutdown, the battery should be charged as soon as possible.
Try to avoid charging before going to bed, because the charging time before going to bed is long, and the voltage at night is unstable. The voltage at night in many places is relatively high and fluctuates greatly, which has a greater impact on the battery.
Generally, the battery of a mobile phone can be charged, used, and stopped at any time. Cycle life refers to the number of full charge and full discharge, and partial charge and discharge can be understood as a fraction of the life. The key to battery use: the battery is fully charged, and it can be charged for 20 minutes to half an hour to reach saturation, but it must be avoided to charge for a long time after being fully charged.
Precautions
Lithium battery mobile phones or chargers will automatically stop charging after the battery is fully charged, and there is no so-called "trickle" charging that lasts for more than 10 hours as a nickel battery charger. In other words, if your lithium battery is fully charged, it is also white charged on the charger. And none of us can guarantee that the characteristics of the battery's charging and discharging protection circuit will never change and the quality will be foolproof, so your battery will be on the verge of danger for a long time. This is another reason why we oppose long charging.
In addition, on some mobile phones, after charging for a certain period of time, if the charger is not removed, the system will not only stop charging at this time, but also start a discharge-charge cycle. Perhaps the manufacturer of this approach has its own purpose, but it is clearly detrimental to the life of the battery and mobile phone/charger. At the same time, long-term charging takes a long time and often needs to be carried out at night. According to the situation of my country's power grid, the voltage at night in many places is relatively high and fluctuates greatly. As mentioned earlier, lithium batteries are very delicate, and their ability to withstand fluctuations in charging and discharging is much worse than that of nickel batteries, so this brings additional dangers.
In addition, another aspect that cannot be ignored is that lithium batteries are also not suitable for overdischarge, and overdischarge is also very detrimental to lithium batteries.
