Scientific popularization of smartphones

What percentage of mobile phone battery power is best for charging?

1. It is best to charge the mobile phone battery to 65%-75%. According to experts, the power ratio of smartphone lithium batteries remains between 65% and 75%, and the battery life is at the beginning. It's time to charge when the battery is near 20%.

2. In theory, keeping the battery power in the middle range (such as 30%-80%) is more conducive to extending battery life. Therefore: (1) After the mobile phone is fully charged, it is recommended that you unplug the charger to avoid Charging for a long time or being in a high power state for a long time accelerates the aging of the battery to extend the battery life.

3. How much battery power is best for charging a mobile phone? The optimal range for charging a mobile phone is between 20% and 80%. Charging within this range can avoid excessive charging and discharging of the battery and is beneficial to extending battery life. Of course, this range is not absolute, as there may be slight differences between phone models and battery types.

Popular Science: What are the differences between the various series of Huawei mobile phones?

1. The difference between the five series of Huawei mobile phones is their different positioning. Huawei Mate series Huawei Mate series focuses on large-screen business and is targeted at high-end business people. It is Huawei's most high-end product series at present.

2. Mate series: Huawei Mate series is a series of medium and large mobile phones with larger screens, longer standby time and larger battery capacity, and also supports 5G networks. Mate40 has added face recognition, and the upgrade speed is also very fast.

3. Differences between Huawei’s five mobile phone series Differences between Huawei’s five mobile phone series Nova series: fresh meat series, mainly for young female users, and the price is cheaper than mate series and p series.

Informal science! What is the "memory fusion" that is popular in the mobile phone circle?

1. There are two types of memory fusion technology, one is zram and the other is swap. The former is Divide a piece of physical memory and compress the inactive areas of the application.

2. Memory fusion is a technology developed by the operating system to improve memory utilization. It can use part of the storage space for caching to improve application performance. Therefore, if you need to improve the performance of your application, it is necessary to turn on memory fusion.

3. The essence of memory fusion is to fuse ROM (flash memory) and RAM (operational memory) through algorithms to temporarily increase the RAM space, which can enable more applications to be loaded at the same time and greatly increase the number of background applications kept alive. Optimize the usage experience in multi-application scenarios in the background.

How many times a day is the best time to charge a newly purchased mobile phone (free popular science on charging new phones)

1. The genuine mobile phone battery is set to "sleep state" by the manufacturer before use. The battery process Only after three to five complete charge and discharge cycles will all the chemical substances inside it be "activated" to achieve the best use effect; the specific method is: charge the first three times for 14 hours each time, otherwise the battery performance will be reduced.

2. Generally speaking, if it is a new mobile phone, it can be charged once a day. If you bought it for two or three years, then charging it for half a day will be enough. If you bought your mobile phone for more than three years, you may need to flush it again in a few hours.

3. Nowadays, they are all lithium batteries, and there is no limit on the number of times. When the phone is below 20%, charge it in time. Unplug it immediately after charging to 100%. Don't overcharge. Do not charge for a long time.

4. Charge the new mobile phone for the first time, just fully charge it. Do not wait until the battery is in a low power state before charging the battery. Try to charge it as you use it to extend the service life of the battery. Please remove the charger promptly after the battery is fully charged to avoid charging for a long time, otherwise it may damage the battery or shorten the life of the charger.

5. How long does it take to charge a newly purchased iPhone? You don’t have to charge it for 12 hours for the first flush, it just needs to be fully charged. Additional notes on charging: Charging is possible at any power level. It is best to have a complete discharge and charging process once a week, that is, from red power to full power.

Why do smartphones consume a lot of power?

1. Multiple background programs are running at the same time. During the continuous high-intensity operation of the mobile phone background, Its own power consumption will naturally increase. Users can use some tool software to help us optimize the energy saving of mobile phones, making it more convenient to use.

2. Fast power consumption in low-temperature environments (use mobile phones outdoors in winter): The activity of lithium batteries deteriorates at low temperatures. This is a normal phenomenon. When the mobile phone returns to normal room temperature, it will return to normal. The normal working environment temperature of mobile phones is 0℃~35℃.

3. Nowadays, smart phones are all large-screen mobile phones, which indeed consume a lot of power. Generally, the standby time is less than 10 hours. It can be considered that mobile phones consume power quickly. The power consumption of mobile phones is generally due to APP software and system. and battery reasons.

4. The screen of a smartphone is larger and consumes more power, causing the smartphone to drain power quickly. There are too many background applications on the smartphone, which consume a lot of power, causing the smartphone to drain power quickly. You can try turning off the background applications. The battery capacity is small, and small-capacity lithium batteries are more easily fully charged, resulting in faster charging of smartphones.
