Mobile phones have become an indispensable part of modern people's lives, and almost everyone owns at least one smartphone. For newly purchased mobile phones, the first charging time has always been a controversial topic. Many people believe that the first charge should be fully charged, while others believe that it only needs to be charged for a period of time. So, how long does it take to charge a mobile phone for the first time?

It usually only takes 2 to 4 hours to fully charge a newly purchased lithium battery mobile phone for the first time. If you want the battery to last longer, you can continue to charge for about 15 minutes after the prompt is full. But do not charge for longer than 12 hours, otherwise it may damage the battery life or cause safety hazards

First of all, we need to understand how the mobile phone battery works. Modern smartphones usually use lithium-ion batteries, which have the advantages of high energy density, lightweight, and no memory effect, making them the first choice for mobile phone batteries. The charging process of a lithium-ion battery is by moving lithium ions from the positive electrode to the negative electrode, and then moving the lithium ions from the negative electrode back to the positive electrode through the discharge process. Therefore, the charging and discharging of lithium-ion batteries is a cyclic process.

For newly purchased mobile phones, manufacturers usually charge the battery to a certain extent before leaving the factory to ensure that the mobile phone can start and operate normally. Therefore, when we first get a mobile phone, the battery usually already has a certain amount of power. According to expert advice, we do not need to charge the mobile phone's battery completely after it is completely exhausted, but can charge it when the battery power is less than 20%. This is because the life of a lithium-ion battery is determined by the number of charges, and frequent full discharge and recharge will shorten the life of the battery.

However, we do not need to unplug the charger immediately after charging the phone to 100%. In fact, leaving your phone plugged into the charger for a long time will also cause some damage to the battery. According to expert advice, when the phone is charged to 100%, we can unplug the charger to avoid overcharging. In addition, if we need to use the mobile phone, we can charge it again when the battery power is less than 20%.

In addition to charging for the first time, we should also pay attention to some charging tips when using our mobile phones daily. First, avoid using inappropriate chargers and data cables. Use original chargers and data cables to ensure charging stability and safety. Secondly, avoid overcharging and over-discharging. Try to keep your phone's power between 20% and 80%, which can extend the battery life. Finally, avoid charging in high temperature environments. High temperature will accelerate the aging of the battery, so you should try to avoid placing your phone in direct sunlight or near a heat source when charging.

To sum up, there is no fixed time requirement for charging a mobile phone for the first time, but we can charge it when the battery power is less than 20% and charge the mobile phone to 100%. In addition, we should also pay attention to daily charging tips to extend the service life of the battery. Through the correct charging method, we can better protect the mobile phone battery and extend the service life of the mobile phone. .
