I don't have much electricity power, but I can still use it for a long time

He took another cartoon to show to his brother who didn’t understand what life is like for ordinary people.

The picture above shows a man sitting on the toilet looking at his mobile phone. A charging cable is drawn from the toilet and inserted into the mobile phone in the man's hand.

He said: You see, human beings can't do without charging. We really need to turn the toilet into a charger.

His brother's mouth was shriveled and said: “If it leaks electricity, his butt will feel better.”

Then, the brother's sermon began:

“In fact, human beings have too much desire and want too much. When I go to the bathroom, I just concentrate on going to the bathroom. Do I have to watch my cell phone? Screen brightness to be set so bright, video resolution to the highest, the game to the latest force. Of course, the electricity is not enough. We have to charge it all the time.”

He listened with disapproval. He was used to it anyway. When the brother finished, he took over the conversation: “Don't you need to recharge?”

Brother did not speak, went to his own screen to write some words, and then showed him the e-reader, the battery had been shown to almost run out.

There were sentences on it: I don't have much electricity, but I can still use it for a long time.

Why do e-readers save electricity

For display electronic products, one of the largest components of electricity consumption is of course the screen. The most unique feature of e-readers is the screen, which often uses e-ink screen.

Because the display unit has the characteristics of bistability, it does not need power consumption to maintain when displaying the content. It only needs power consumption to refresh the display units when updating the content, such as turning pages.

In the scene of E-reading, the proportion of page turning time is relatively small, so it is very energy-saving. Moreover, in order to improve the page turning experience, the screen of the current e-reader often adopts partial update technology, and only carries out a full update after many turns, which also saves power consumption.

In the recommended use scenarios, e-readers reflect the ambient light to display, that is, they don't use the built-in lights. New e-readers often have built-in side lights, but they can be turned off. This is not like the LCD screen which can only be displayed with backlight turned on, so the power consumption of the e-reader is also greatly reduced.

Of course, in the scenario of E-reading, the functions of electronic products are relatively simple, so the power consumption of CPU is relatively low, and the power consumption is also less.

Is e-reader power saving helpful to environmental protection

Just from the perspective of power consumption, in fact, mobile phones and tablets, which are commonly used electronic products, account for a small proportion of human power generation. Therefore, the electricity saved by e-readers accounts for a small proportion too. From the perspective of power saving alone, the direct impact on environmental protection is relatively small.

But indirectly, if the power consumption is very low, then the battery can be made smaller to reduce the pollution in the battery manufacturing process, which is also beneficial to environmental protection.

What is the good experience of lower electricity consuming

In fact, the good experience of power saving is mainly to reduce the dependence on charging. One charge a day or one charge a week, the experience is very different. On the other hand, if you have to charge while using it sometimes, it's very troublesome and dangerous.

The other is for portability. After all, there is a transformer in the charger, and the weight is certain. If you only need to charge the battery once a few days, you usually don't have to bring the charger with you all the time, so as to make room for your bag and reduce the burden. People will also be relaxed.

In addition, the high power consumption parts often heat obviously, and the handle will be poor in the process of use. Heat tends to make people feel irritable, while cool makes people calm and conducive to concentration.

What can be improved in the future

As mentioned above, the main embodiment of power saving is not the power consumption. In the power saving concept of electronic products, the main thing is the working hours.

E-readers have been able to work long enough without charging. However, with the development of technology, such as the improvement of e-ink screen refresh rate and the development of color technology, the way people use e-readers has changed, and some people even take them to watch videos and play games.

Under this new application scenario, the power consumption is estimated to have increased a lot. Can we further improve the technology to alleviate and compensate this new demand? Let’s wait and see.

I don't have much electricity, but I can use it for a long time

Of course, no matter at any time, the initial supporters of e-readers, there will still be a group that adheres to the most traditional way. E-readers are mainly used for reading, and the users of them are willing to enjoy the black and white color. The number of users of this group may be small, but they may be the most proud ones.

They may be able to hang your soul with just a few words: I don't have much electricity, but I can still use it for a long time. People should not have too many desires.
