I think after spending a lot of money to buy an Apple mobile phone, many users will be very concerned about one value of the mobile phone, namely the battery health of the Apple mobile phone. We all know that the battery health status of Apple mobile phones is 100 after leaving the factory. As the usage time increases, the battery will inevitably suffer loss. This will be intuitively reflected in the battery health numbers. However, some users will find that the battery status of the new mobile phone they just bought has dropped to 95% after using it for a month, and some users have only dropped to 98% after having used it for six months.
So at this time, someone will definitely ask, they are both Apple phones, why is the loss so different? To fully understand this problem, we mustncerned by our daily usage habits. In our daily use of mobile phones, some people like to play games while charging when the battery is exhausted, some people like to use the mobile phone until it is completely turned off and then plug it in to charge, and some people use it that much. according to their needs. Charge as much as you want, so different usage habits won't cause any loss to the battery.
Most cell phones on the market now use lithium batteries. The advantage of lithium batteries is that they have a memory function and do not need to be discharged to less than 20% before recharging like previous mobile phones. So the battery as a consumable, different usage levels and frequencies will also affect the battery life. If you still like nBrowsing Weibo and playing King of Kings while charging, the battery will be charged and discharged to a large extent. This will increase battery loss, thereby affecting its lifespan. If you want to use it until it is discharged and then charge it, the battery power will be reduced and the performance will be significantly reduced. this time, in order to meet normal power consumption, the battery will naturally be overcharged, reducing battery life.
The concept of trickle charging has long been popularized in mobile phones. The advantage is that it can charge the battery with a low current when it is close to a maximum charge state. Where possible, thereby better maintaining the maximum battery life, thereby protecting its lifespan. During use, if you frequently use the battery power below 20% beforecharge it, the battery health will decline quite quickly.
Taking my personal experience as an example, I bought an iPhone and I don't use it even when it's charging. Battery health is always maintained at 100. Once the novelty wears off, I start using it until it runs out of battery and then I recharge it. Sometimes I still play while charging, but it turns out that the battery health has not been healthy for a month. It rose to 98. Later, I continued to maintain the habit of loading that much. as I used it, charging as I used it, charging without playing, and the battery health remained at 98 for two months.
It can be seen that in order to maintain longer battery life, it is recommended not to charge while playing or to charge when discharged. For users who are afraid of battery quality issues after ayear of use, there is no need to worry, because Apple's official battery warrantyUsers can replace the battery for free within one year when the battery condition reaches 80% . And in many cases, you don't need to pay too much attention to its condition. It's very likely that after three months of use the battery will go straight from 100 to 98. This is also within a reasonable range, if you do. use it normally. Usually there is no big problem. Even if the battery is abnormal, it can be replaced by the official.
However, mobile phones are consumables after all, and wear and tear is also a normal thing. Normal cell phones usually only have an average lifespan of two or three years, so we always have to use them accordingly. to our own habits. How to use it is always how to use it. After tout, cell phones are used for consumption. If you still worry about the health of your cell phone, then you are putting the cart before the horse.
What is the English word for battery tab?
A car battery needs to be replaced when its life is less than 10%, but it can still be used after 53% .
If the battery voltage is 10% lower than the rated voltage, i.e. less than 10.8V, the battery life may be reduced by 80%. You can also use a charger to charge to avoid wasting power.
When the battery power is less than half, that is, when the voltage is less than 13.4V, the battery fault indicator light turns on and it is difficult to start the car. It must be loaded on time. The engine should be kept above 1,500 rpm and loaded for more than 20 minutes. He phad to be started once and maintained. Charging for more than 30 minutes at 1500 rpm or more can be used to start once the next day. It is recommended to check the battery and observe the color change of the battery's "electric eye" to determine if it needs to be replaced.
Battery life
The life of original car batteries is 3 to 4 years, and the life of ordinary car batteries is generally from 2 to 3 years. Battery life is related to the configuration of the vehicle and electrical equipment.
For example, it is equipped with navigation, multi-screen information display and remote anti-theft. The functions are used a lot because the vehicle continues to consume power when it is turned off, causing. the battery discharges for a long time, which is harmful to the battery. The warranty period of the battery is1 year; Being careful not to lose power will extend battery life.
. iFlytek
iFlytek is a voice-to-text product owned by iFlytek. As we know, iFlytek is the largest voice technology provider in China. intelligent voice technology. The advantage of iFlytek lies in its brand support and mature technical support. Only “iFlytek” guarantees product quality.
iFlytek supports Android, iOS and Web versions. It is divided into ordinary, advanced and VIP accounts. There are differences in trash recovery, voice typing time and download traffic limit. Some features require payment. . to use. The main functions are as follows:
Real-time speech to text: convert while speaking, save recording files and text together, support editing and repeat playback, and facilitateread manual arrangement and proofreading of content.
2. Sogou Dictation
Sogou Dictation is more vertical and simpler than iFlytek Voice Note, and is only intended for voice note taking. Designed for individual purposes, it also supports multi-end synchronization. It is divided into two modes: narrative writing and recording interviews.
Note writing: It collects a large number of literary works, focusing on the recognition of literary vocabulary, and is suitable for recording notes, memos and diaries. With this function, speech to text is converted immediately after recording and supports playing and continuing recordings as well as editing text.
Interview recording: News database is connected to it and hot words are collected, making vocabulary recognition in meetings, interviewsand more precise lectures; it can also list key points and summaries for easy organization later. However, this function can only realize text conversion after recording is completed, and it is easy to cause incomplete text recognition due to unclear recording.
3. Xixiyuji
Xixiyuji is the latest text-to-speech application launched online. It is always improved and updated. This software has more features than the previous two. is audio import, that is, there are no restrictions on recording. Audio files can be saved through other tools and then the software can be used to convert text. The advantages of this function are: more application scenarios and more convenient audio file recording. For example, use a voice recorder and other tools to record classroom content, then use the software after class to achieve the text recording goal.
Supports recognition in recording scenarios at a relatively long distance (within 0.5m), suitable for conference use. However, these three types of software cannot achieve long-distance recording, so it is recommended to use other tools to capture and then import and identify, and Xixiyuji just has this function.
Freedom is also its advantage. There is no limit on the number of words shared and no limit on voice length. Currently, only Mandarin, Sichuan, Cantonese and English text recording recognition is supported.
Based on the charging power, calculate the minimum rated energy capacity of the battery.
The English word for lug is usually represented by the word lug. For example, plate lug. Some people usealso read tab to mean tab. For example, electrode tab, cathode tab, anode tab. Judging from its Chinese translation of "electrode ears (wearable)", the translation "pod" is more formal.
The minimum rated energy capacity of the battery is 1.83 KW·h.
Solution process:
36.7/20=1.835 (KW·h)
Power (English: power) is the amount of work done per unit of time or energy conversion High power is low. If we consider the work done over time, the average power during this period is given by: Instantaneous power is the average power as time approaches 0: When discussing energy conversion problems, it is sometimes replaced by letters.
Power is a physical quantity that represents the speed at which work is performed. The relationship between work and the time required to complete a jobvail is called power, which is numerically equal to the work done per unit of time and is represented by P. If the work dA is done in the time interval dt, then the power is equal to the dot product of force and speed of the point on which the force is applied.
