The higher the better pixels? 20 common sense only one mobile phone is right

On cell phone tips, for those who do not understand the phone you have heard such words:

"Mobile phone battery must be used up to recharge."

"It's all right to put rice in the mobile phone

"Phone must be unplugged when fully charged

In fact, many of the common sense of mobile phones, which are generally circulated by us, are wrong. I have summarized the common knowledge of 20 popular mobile phones at present, and guess what is true.

1, the phone is fully charged must be unplugged

error!

I had my first mobile phone in high school. At that time I was very much concerned with my mobile phone. I was very cautious with each charge. When I charge to 100%, I am worried about whether the battery will be overcharged Current 'damage, in fact, this idea is wrong.

First of all, for the current mobile phone, most of them have a power management system, it will automatically stop the input current when fully charged, will not overcharge problem.Secondly, today's charger has a full automatic stop function, dual protection allows users Do not worry about this problem at all, is it a bit embarrassed if there is a phenomenon of 'inflated' and the 3 billion cell phone users in the world will have to keep their cell phones to 100% of the scenes?

2, cell phone dropped into the rice heap just fine

error!

New Year's Day holiday in 2018 boring, I read the fast hand to see a video of the maintenance of mobile phones, producers tell you: the phone out of the water into the rice just fine, in fact, this argument is nonsense, an agency has Do related experiments, if the phone just splashed water, into the rice heap Perhaps useful, if dropped into the water, then the role can be neglected.To put the phone into the rice, is not it became the legendary 'yellow braised rice.'

The correct approach is:

1. One of the first things to do when it comes to water in electronics is to turn off the power and prevent the components from burning out.

2. Wipe the surface moisture, if it is viscous drinks, soup and other substances, you can use a wet wipe or damp cloth to wipe.

3. Check the product water level, if there is no obvious water mark, gently squeeze the gap to see whether the liquid in the gap.

4. See the obvious moisture, open the phone, the circuit board immersed in a little anhydrous alcohol, stirring, remove and dry. / If you can not see the obvious liquid, please place it in a dry, well-ventilated place, or with dry thickness Towel, facial package temperature steaming.

5. If excessive water intake, and no treatment of anhydrous alcohol and other objects, it is recommended to the official maintenance point for repair.

3, the phone will not be leaked after factory reset

error!

At present, many people have been experiencing the sale of mobile phones, the used mobile phones have been restored to the factory settings, and then to third parties to deal with.But you know, the phone is restored to factory settings, there is still the possibility of divulging personal privacy.

In other words, the old phone to delete all the stored things, and restore the factory settings, or can have a way to get the file information before deleting.In fact, both the phone and the file recovery on the computer belong to the same token, the ordinary delete files Or restore the factory settings, the phone just made a 'can cover' tag of the data, indicating that this can be covered area can be used for other file storage, rather than a real delete, for example, you accidentally deleted a Important documents, through the recovery tool for processing, and finally got the original, the data in the phone is also through technical means to restore the mutual trust data recovery is to restore the Android phone, iOS mobile phone delete the information software.

How to prevent it, before you sell your used mobile phones, be sure to restore the factory settings, the number of download several APP software or several movie TV series, the memory is filled, then cleared, after repeated several times, Finally restore the factory settings, so do not have to worry about your personal privacy is being used by the "heart." Although you are not a big star, there is no million worth, privacy or pay attention to the next.

4, mobile phone power must be used up to charge

error!

Mobile phone used to automatically shut down and then recharge the phone is that many 'game party' often experienced, long-term play games, power consumption is too large, the Council did not shut down automatically shut down. And this phenomenon is not only very bad, but also Will cause some damage to the phone's battery.

Most of the previous smart phones use nickel-metal hydride batteries, and now most of the mobile phone products on the market for the use of lithium batteries, although there is no memory effect of nickel-metal hydride batteries, if the user wait until all run out of electricity after the red will lead Lithium battery internal chemical reaction can not reduce the life expectancy, the best way is to maintain a high power anytime, anywhere, so that the battery life will be long.

5, mobile phone while playing charging affect battery life

error!

When the phone is charging, the charging voltage at both ends of the battery is higher than the terminal voltage of the battery, and the battery will not discharge. At this time, the battery runs as a load in the circuit, and the power supply of each component of the mobile phone is provided by the charger, therefore While charging the phone while playing things, in theory, the impact on battery life is not large.

Experience a lot of shop filled with electricity for the user to play the phone, is not bad fast yet.

6, iOS system upgrade more card

correct!

Many people who use the iPhone have this feeling, the more the more the feeling of upgrading, with some time ago Apple 's "down-door" intensified blink of an eye in 2018, the incident is gradually coming to an end, the first time Apple brought to the user Apologized statement announced the iPhone to replace the cost of reducing the battery.And Apple's recent announcement showed that it accelerated the user to provide low-cost battery service plan, in late January 2018 can be implemented.

In other words, as Apple added a limited frequency before the aging battery measures, the user's battery began to use after aging, the subsequent system upgrade also will be more and more cards, Apple said no further down-conversion, and in 2018 In the iOS update released early this year, there's a new feature that lets users check the health of their iPhone battery, and the mother no longer has to worry about getting stuck with my iPhone.

7, cell phone pixels high, imaging will be good

Not exactly right!

Affect the quality of the many factors, of which a very important point is the size of the sensor components. Literally, the light-sensitive components, and the light is related to the quality of the image depends on the number of photons captured by the photosensitive element to determine the number of photosensitive elements The larger the photons that can be captured, the better the sensitivities, resulting in a more subtle image quality with a higher resolution.

This is why the 800W pixels of the apple take photos better than the other 1200W pixels phones, the 500W SLR like to kill the 1600W mobile phone camera, a great reason is because of its house (sensor) is large, and it lives in the (pixel Of course, the quality is not only sensitive to the size of the sensor is closely related to the structure of the lens, the same software optimization, just from the pixel size can not see the picture quality Excellent and bad.

8, the number of mobile processor cores run faster?

Not exactly right!

Android mobile phone operating speed is mainly reflected in the processor level, resulting in many manufacturers advertisements 'speed quad-core, true octave' and other promotional language level is not poor, in fact, the number of mobile CPU core number and not Delegates must be fast.

Factors affecting the processing power of the processor are many factors, such as process, clock speed, architecture, bandwidth, etc., but not with the increase in the number of cores is proportional to the increase.Currently, the mobile computing demand is not great , Quad-core mobile phones and eight nuclear mobile phones, often only use a small amount of the core, this time the key to running speed depends on what kind of single-core processing capabilities. So, Multi-core processors can do more calculations at the same time, but have nothing to do with the speed of calculation.

9, mobile phone support fast charging faster

Not exactly right!

Earlier, an old friend bought a mobile phone that supports fast charge. At first, he felt the charging rate was very fast. After half a year, the charge was slowed down. He asked me if it was a problem with the phone. I asked him what charge He told me to buy a small ordinary store charger, I told him that the charger does not support fast charge, light phone is useless, must be used together, heard my advice, he restored using the original charger Previous 'high rate' charging effect.

So, the charger is best to use the original, so as to maximize the protection of the battery, and the original charger voltage, data, the most suitable for the phone.

10, the phone must be foil

Not exactly right!

Today's mobile phones mostly use tempered glass materials such as Corning, in theory, its hardness is higher than the average metal 5.5, cell phone manufacturers try their best to touch the touch experience, a layer of film affixed inevitably destroy the user experience, so that Do not necessarily have to foil, of course, if you really worried about screen scratches or burst phenomenon, it is recommended to affix a better film.

After writing this article, mobile phone film manufacturers will not hate me yet.

11, for a long time to play mobile games can cause cancer

error!

At present, the development of smart phones is increasingly huge. The number of users who use mobile phones is also increasing day by day. Hundreds of millions of users use mobile phones daily, and a considerable number of users use mobile phones for more than 3 hours every day. Water meter.

From a professional point of view, playing games, there will be no cancer itself, but may cause some highly carcinogenic diseases, such as:

Lack of sleep time

2 diet.

Irregular urine.

There is no proper exercise and so on

So, while playing games does not directly expose you to the risk of cancer, it's still good enough.

12, mobile phone battery rapid development, a minute can be fully charged

error!

A lot of battery black technology is still in the experimental phase, there is still some time before commercial use, so later to see this news can be ignored.If one day in the future to achieve, will charge for a minute, call a week yet.

13, often brush machine to reduce the life of the phone

error!

Brush machine, in terms of popular is to re-write the memory on the phone version, jargon is called flash. Any phone is its system, software, parameters stored in the flash, if there is a newer version of the phone rom file, Brush flash will not have any impact, for most smart phones, due to the new version of the optimization, but also effectively improve the performance of the phone, so often brush machine will not affect the hardware of the phone.

14, bought a dual card phone, both cards can use 4G at the same time

Not exactly right!

Nowadays a lot of mobile phone manufacturers in order to attract users to buy, have introduced all kinds of full Netcom, dual 4G phone, everyone knows there are many tricky.

Dual 4G mobile phone standard is the lowest 5-mode 13-band, many unscrupulous businessmen in order to use the information asymmetry, lied to his cell phone supports dual-4G function, in fact, did not meet the standard 5-mode 13-band, but only 5 mode 8 Or 3 mode 8 frequency, this time you will be fooled.If you are a user running around the world, and need to use two phone cards at the same time, then when you buy a cell phone to be optimistic about its network standard.

15, phone can call 112 emergency helpless signal

error!

There are common sense that the world's first aid numbers are 112, when the phone without SIM card or no signal, call 112 will pass, it will automatically search for all available network calls, 112 is the only card can be plugged in Phone number.

But 112 is actually a common emergency signal in Europe and the United States, in the country does not work, call 112 in the country, you can only hear a recording prompt. The other is the so-called no signal is weak, can only call 112 emergency calls only.

16, the imaging of the viewfinder equals the imaging of the final shot

error!

Before friends have compared the performance of two mobile phone camera, will be two mobile phone viewfinder frame at an object shooting, taking the imaging effect of the viewfinder frame to determine which phone's camera performance is strong, in fact, this approach is Incorrect, you need to shoot, the real shot proofs to contrast, which I did an experiment: Select Sony Sony Xperia XZ1First open the camera interface facing a book, manual focus without shooting direct screenshots.

As you can see, the Sony Xperia XZ1 has been out of place. Let us look at the comparison proofs after clicking shoot.

Proofs enlarged are very clearly visible why this happens, I do not understand to explain to the students:

First of all, the principle of the camera is the lens lighting, the workflow of taking a photo is the sensor to convert photon elements into electronic signals, and then the image processor to convert the electronic signals into human-visual image files, while the viewfinder to see Just taken pictures of the lens, so no matter what kind of viewfinder, the viewfinder screen and the actual picture are different.

17, into the refrigerator aging battery a long time

error!

This rumor is very popular online, but unfortunately this theory is wrong.

First of all, we must recognize that the initial capacity of the battery after aging things can not be restored because the battery after the increase in the number of charge, the molecular heat movement will cause the arrangement of its internal molecules of the onslaught of the results of the destruction of the passage of time, the charge-storage efficiency gradually reduced. Frozen in a certain extent, the original internal structure of the battery subtle changes occur, there may be a short time to increase the ability to charge, but the battery into the refrigerator is not the actual effect is not recommended after the battery aging, only Replace the battery if it is true, Blessed with selling refrigerators and popsicles, a battery of useful life.

18, when the phone is almost no radiation when the radiation is relatively large

error!

'It's best not to call when there is only a gig of cell phone left because the radiation at this time will increase by a thousandfold.' 'This circle of friends has long been rumored and many people believe it. However, this is not the correct theory.

Usually people say the cell phone radiation intensity, refers to the phone's transmit power, the strength of the phone's remaining power without half a dime, but the phone signal strength has a certain relationship.The rumor confused the phone ' 'And' a signal '.

In order to maintain the need of two-way signal communication and reduce radiation of the human body, the cell phone has a function that the cell phone considers it is located close to the base station when the signal is strong, so that the cell phone goes home Reduce the transmitting power. When the signal is weak, the handset considers it as the signal source from the base station. In order to guarantee a good call, it transmits more power to receive the signal.

So, at present, there is not enough evidence to say that when the mobile phone is low-powered, the call radiation is larger. Often with the fast cell phone on the same table, do not give me eraser, it radiates him, the original is a fake.

19, every night have to shut down the phone is good

Do not shut down, why the phone to set 'shutdown' this feature yet

error!

Although the phone also needs rest, but also not frequently to the daily shutdown, because the regular switch, the phone slightly larger loss.

Each time we power off and then boot, the phone has a lot of data to be reloaded to read, which memory will produce some loss, and the more frequent switching, loss greater, despite the good quality of the phone, the impact is not In addition, the regular switch is also more power .Although the frequent switch on the phone damage, a long time do not shut down the same will produce a variety of depth junk files, running for a long time, more and more garbage, it is recommended not to shut down Users, mobile phones reboot once a week, so that the phone system rubbish and various background clean-up procedures, and complete self-repair, which is why every cell phone after the restart to become one of the reasons to become fluid.

20, my phone is full Netcom, travel abroad do not have to change the phone

error!

Although all are all Netcom, but some mobile phone will emasculate some network formats and frequency bands, not all the frequency bands in the world, so some specific countries and regions do not support your phone, it may not be used. To be full of the world to see, not only with enough money, but also look at the network format and band Oh.

Write last

In addition, there is a correct 'common sense' forget to tell everyone that point praise commentators, 2018 Universiade, made fortune, hee hee.
