Nowadays, most of our mobile phone batteries are lithium batteries. Many times, when we buy a mobile phone, salespeople will tell us that the phone needs to be charged for 12 hours in the first 3 times. However, there is a misunderstanding about this. This is a continuation of the statement from nickel batteries (such as nickel cadmium and nickel hydrogen). So this statement can be said to have been a misunderstanding from the beginning. The current one is a lithium battery, and there is no saying that it can be charged for 12 hours for the first time. Just fill it up, and the automatic protection circuit in the machine will automatically cut off the power supply. Recharging it again is useless. Previously, batteries had a memory effect, so they had to be fully charged and then discharged several times in a row to expand their capacity. The birth of lithium-ion batteries was developed to overcome the memory effect, and they were already activated at the factory, so there was no need to charge them for 12 hours. What you need to do is that the battery has a certain amount of time from the factory to selling to you. Just charge it for one or two more hours to reactivate the lithium-ion, which usually takes four to five hours for 1000 milliamperes.

The charging and discharging characteristics of lithium batteries and nickel batteries are very different, and it can be very clear that all the serious formal technical materials I have consulted emphasize that overcharging and overcharging can cause huge damage to lithium batteries, especially liquid lithium-ion batteries. Therefore, it is best to charge according to standard time and methods, especially do not charge for more than 12 hours. Usually, the charging method introduced in the phone manual is the standard charging method suitable for the phone. 5-6 hours is sufficient.

Charging knowledge:

The statement about how long it takes to charge a newly purchased battery in order to "activate" the battery is not entirely correct. A new battery can be purchased and placed on a mobile phone, and can be fully charged a few times to reach or approach the nominal capacity. The charging time is related to the capacity of the battery and the charging current it starts with. But it is recommended that new battery buyers use the original direct charging method on their phone to fully charge the battery after using up the battery for the first three times. The time standard is generally to leave the phone in the fully charged state for an additional hour

In addition, lithium battery phones or chargers will automatically stop charging after the battery is fully charged, and there is no "trickle" charging that nickel chargers refer to as lasting for more than 10 hours. That is to say, if your lithium battery is fully charged and placed on the charger, it is also a white charge. And none of us can guarantee that the characteristics of the charging and discharging protection circuit of the battery will never change and the quality will be foolproof, so your battery will be on the brink of danger for a long time.

As for the sales of mobile phones, it is generally ignorant to tell you that they need to be able to charge for 12 or 24 hours. The most important purpose is to charge it for 24 hours and then charge it three times in a row. So, if you think about it, the seven day warranty is too long. When you have used it for more than seven days, you can exchange it for a maximum of 15 days. Even if what I mentioned above doesn't count, currently 200% of the batteries on the market are lithium-ion batteries. The average charging cycle and lifespan are around 800 times, which can be used for at least three to four years. Nowadays, people usually replace their phones every two years, which is faster. Is it necessary to protect the battery like this!? If you have the opportunity to go to any after-sales service, you can ask this question. The answer is the same, just fill it up. Generally, people who answer you for 12 or 24 hours are spreading false information. May I ask if their actions are not due to insufficient batteries.

How long does it take for an iPhone to charge for the first time?

The highly anticipated iPhone 8 and 8Plus were officially released early this morning. So, how long does it take for iPhone 8 to charge for the first time? How long does it take for Apple 8 to fully charge? What are the things to pay attention to when charging an Apple iPhone 8 to prevent premature battery reimbursement? Below, Yizhi Mushroom will bring you the first time charging precautions for an Apple iPhone 7. Let's learn together!

The iPhone 8 has undergone significant upgrades in terms of exterior design and hardware compared to the previous 7, but it seems that it has not brought any improvement in terms of battery life.

The range of iPhone 8 is basically consistent compared to 7, but there is no mention of whether it supports fast charging. According to official website data, the iPhone 8 can charge up to 50% of its battery in 30 minutes, with a special label stating that it has a built-in lithium-ion charging battery, wireless charging (compatible with various Qi chargers 10), charging through a computer's USB port or power adapter, and fast charging. This means that the iPhone 8 has finally achieved support for fast charging.

As for how long it takes for iPhone 8 to charge for the first time, the editor suggests keeping your phone's battery level above 15%, which can help extend battery life. Because the Apple 8 is equipped with a lithium-ion battery, the first and subsequent charges are always charged at around 15% -20% of the remaining battery level, fully charged.

The main change of iPhone 8 is the return to double-sided glass design. It should be emphasized that it is still equipped with a 5V/1A adapter, which is a bit disappointing, but supporting fast charging is also worth praising.

How long does it take for Huawei's new phone to charge for the first time?

Huawei phones can be fully charged for the first time.

1. The new battery head should be used three times until the low battery alarm is triggered, and then combined with the original direct charging, the phone should be fully charged when turned on, and then continue to be charged for about 1 hour.

2. In daily use, it is good to fully charge the battery. To avoid prolonged charging, it is recommended to use an alarm. In case of shutdown, the battery should be charged as soon as possible.

3. Try to avoid charging before bedtime as it takes a long time and the voltage at night is unstable. In many places, the voltage at night is relatively high and fluctuates greatly, which has a significant impact on the battery.
