Lithium battery maintenance methods: mild, quick release fast charge

Calculate your side the number of mobile devices? Mobile phones, MP3 players, tablet computers, notebook computers, digital cameras, handheld, navigation systems, etc., these devices are using mobile battery-powered, the battery life is the most worrying problem.

Mobile phone, for example, in addition to the system power consumption factors affect the battery life, the knowledge of how to care for the battery also must understand, in fact, with this phone like the iPhone battery can not be replaced unless you can bear to replace the backup battery or external Dell Inspiron 15R N5010 battery .

Maintenance of the battery may have little effect on a single charge and discharge cycles, but after a long time there is contrast, lithium-ion battery in use after a year or more, the battery capacity loss, and better maintenance of battery wear and tear will be much better.

Also spread before the Internet there are many methods on the maintenance of the lithium-ion Dell Latitude D620 Battery, but different opinions. For example, after a new battery to get it back to full 12 hours and then vented to activate the maximum capacity of three times in a row, also say that every month there must be a complete charge and discharge process is conducive to maintenance.

Foreign Battery University website recently released an article on How to prolong lithium battery life, new conclusions on the use of the battery.

They claim that, after the experimental results show that the best maintenance of the lithium-ion battery is mild use, quick release fast charge, which is similar to the use of machinery and equipment, the greater the frequency, the more the number, the loss of the battery will be more fast. The smaller the degree of depth of discharge lithium Dell Inspiron 6400 battery, use the longer, if possible, try to avoid frequent full charge and discharge.

Users, your battery by 10%, 20% charge is the best, the remaining battery charge in 50% of the time can, but try to avoid the phone prompts for low battery starts to charge, no matter what the conditions are not run out of battery power. If you're out, try to use a larger capacity battery or mobile power.

The most stable Windows notebook was actually MacBook Pro

The market running Windows 7 and Windows 8 laptop There are hundreds of models, who will win the title of best Windows notebook? Which laptop running Windows is the most stable, at least crash, blue screen of death at least? A study surprising results, this notebook is not from Dell, Lenovo and other PC makers, but from Apple.

Toshiba hair the super pole Kirabook screen resolution of 2560 x 1440 pixels

In Windows8 world, no shortage of high-end machine and "downsizing" machine, but has never had one, these two features can be combined together equipment. Recently, Toshiba has released a named Toshiba Kirabook, ultra-extreme, it is precisely with these two features. Toshiba KIRA product line which is the first PC products, is regarded as a strong competitor to the MacBook Pro and MacBook Air.

Configuration, the Toshiba the super pole Kirabook this run Windows 8 operating system, equipped with the optional Intel Core i5 or i7 processor with 8GB of memory space and 256GB internal storage space. The industry believes that if you choose i7 processor may be better, because with a resolution of 2560 x 1440's 13.3-inch ultra-high definition the PixelPure touch screen, you may need more horsepower to drive its smooth running. --- Also worth mentioning is its the pixel density 221PPi, even with the Chromebook Pixel MacBook Pro comparable.

According to official said: "When the staff to show us this ultra-extreme Personally, I think it's great. Many other companies have released products, staff usually to customers who show their products of high resolution, amazing color reproduction and clarity, but often a lot of products because the viewing angle is not perfect, resulting in greatly reduced the overall score. apart is that the, Toshiba Kirabook screen have on the basis of these advantages than the other competitors, do not believe it can sit in front of it personally experience a touch screen is very responsive, running Windows 8 Professional Edition is its capability. Toshiba Kirabook super pole built the models screen management tools, the default setting is very popular, but its operation button is too small and can not adjust the zoom, this vision is not very good friend, but a big problem. staff has also repeatedly stressed to us that the weight and material of the machine's overall weight of 2.6 pounds, the palm rest part of the honeycomb structure to make it more comfortable, the overall use of magnesium alloy, can make the device more solid and strong. "

"Single identified from the feel of the experience, Toshiba Kirabook super pole is very strong indeed and the plane did not appear excessive logo and labels, either from the screen, keyboard, or a whole is clear, clean, neat to see that it is definitely not cheap. "

Yes, it certainly is not a bargain. Toshiba Kirabook ultra-pole starting price of $ 1,599.99 (about 9888 yuan), the price has more than a MacBook Pro, if the user wants to select the higher configuration, its price was $ 1,999.99 (about 12360 million). Toshiba For this price, one powerful reason given is: "Toshiba technical support team will guarantee 24 hours for users to solve any technical problems, and each user's phone will get 45 seconds to answer. "

Toshiba Kirabook ultra-pole of this may not be the most perfect equipment, but from all aspects of the configuration point of view, it is indeed a high-end, with ultra-high-definition resolution Windows 8 laptop.

In fact, a product in the end is not a high-end product, it does not matter, it is important that it is in the end to give users how to use experience. A product, even if the public or the media swirling speculation, coupled with a variety of high-end titles, users enjoy the experience the effects of their own can look forward to, then everything will be to no avail.

Introduction to the development trend of today's hardware

Trend 1: smaller
Historical trend tells us, the development of hardware, Asus K72J battery is in constant pursuit of a more compact. Volume on the advantage that you can easily to bring them to any place, later again, they can even be reduced to a built-in in your clothing or skin. The key to realize this dream is the production speed is faster, smaller, cheaper chips. The use of nanotechnology can make the electrical appliances and digital products more intelligent, function more; Handheld data processing operations, on the other hand, will greatly improve the performance, really become a "tablet" convenient to carry.
Trend 2: more personality
Future computer in the interactive software and chips will have greatly improved. Computer can voice communication with us in the future -- not surprisingly, the so-called voice recognition software also can only recognize our voice, after this software even without our voice, it can read our "lip"! The voice interface will train computer know in the future, when a user turned to it, it knows the master to command, when people leave, the standby is end itself. Well trained professionals believe that the "electronic brain" will be in the next five to 10 years. In addition, more personal computer will be based on more reliable personal authentication systems (such as hand lines, voice control, or iris), so can the greatest degree to the protection of the privacy of users shall be inviolable.
Trend 3: more intelligent
Along with the advance of computer data processing capacity, personal computers will become more and more intelligent. Through continued ascension of the hardware performance and more effective control software, can active learning of the PC will eventually have a birth date. Create some wisdom "smart people" there are many technical obstacles, but develop "smart PC" is promising. Chess grandmaster Garry kasparov in 1997 in the "man vs. machine" to the computer also let a person can remember clearly "deep blue". In the future smart PC  Asus K52J Battery also more can bring convenience to the host. It will be able to gradually understand his needs according to master every action, grasping his intention, and seeking the information passively to actively contact information.
Trend 4: cheaper
In November last year, the UN secretary general kofi annan and the United States mainly IT specialist GeLuoPang emperor in Tunisia has released $100 laptop prototype, the green computer is designed for millions of children in poor countries. This "clockwork notebooks" and low power consumption. Computer design is: $100, 500 MHZ processor, 1 gb of ram and innovative dual mode display - both full color display, also have sunlight readable display mode black and white. 's said, monitor computer look like e-books, and computer. The laptop power supply available external power supply, battery, or use the connection on the computer a clockwork crankshaft generating their own power, because the remote areas without electricity in many countries.
Trend 5: more "wireless" (infinite)
To communicate with any machine in any place. At present, with the popularity of the Internet, office desktop personal computers, various functions are being distributed, transfer and melt into people carry a PDA, watches, driving cars. Connected to the computer can control the lights, TV, stereo, security systems, air conditioning, heating and even lawn sprinkler device. All the control signal can usually be issued automatically. PC network also means that the home network (short range network) with adjacent network, office network and long-distance communication network there is no gap between each other. Our PC will not just a personal Asus A32-N61 Battery computer, its function has already been extended to more depth of field, become the new personal communications, computer, a control, computing, storage, communication and entertainment all function as one of the super toolkit. As long as you open the box, everyone can be in the bathroom, office, swimming pool... In any place and any similar or machine to realize communication. "
Trend 6: more common
Now, many computer manufacturers agree that PC development direction will be a ubiquitous computing environment. More and more ordinary household appliances with the function of the PC, the user can handle financial or surf the Internet at home. Future PC will through all kinds of electrical appliances product with computer ability, such as TV, in the form of a set-top box to construct sound and ubiquitous PC Asus A32-F3 Battery environment. In public places, host server will be capable of operation in network architecture is a kind of mobile and wireless computing environment. Users only need to carry with IT equipment, do not need to do any connection, using the infrared transmission mode, can at any time from the public on the server host to receive your email, and other important information.
Trend 7: more fashion
In future society, the design of the product with the function of the product itself is just as important, only more fashionable products can seize the hearts of the consumers. The future of the PC will win a major breakthrough in appearance design. In fact, apple's iMac "design is one of development trend in the future, product integration, and operation can be done by screen rotation different angles. At the same time, in order to make the PC more attractive in appearance, manufacturers are looking for new materials to reduce the PC plastic. Apple, for example, has introduced a titanium and aluminum alloy material.

Users think that Samsung Galaxy phone is easy to use than the iPhone

Has been Apple's iOS operating system is the most simple and easy-to-use smartphone operating system. Despite the iPhone freely customized features and interface very few, but that at the same time also means that in the normal use of the process, we basically do not experience what difficulties will not fiddle with the phone too chaotic for group. Straightforward single the HOME interface means that all your applications are in the same level, while the other hand, the the messy Android system desktop plug, shortcuts, how many will make some people dizzy. There is, the user's psychology is indeed difficult to fathom, so some people are too lazy to design their own desktop screen on the display content, electronic products they always want to look and act like the simpler the better. Samsung R580 Series Battery

Google, however, does not think so, it rich custom space reserved for the Android system, users can choose according to their preferences. People for select Android operating system or iOS operating system, the focus of debate for a long time these days, it was actually a personality first or ease of use is king?

In fact, a certain point of view, this argument is losing significance. Android's customization really means complex, cumbersome and difficult to use this? Not necessarily the case.

A company called the consulting firm of Siegel + Gale's recently released a survey report, the investigation report for the Samsung Galaxy series phones and Apple's iPhone usability interviewed 400 mobile phone users, the final results showed that most are Investigators believe the Samsung Galaxy series phone running the Android operating system is doing very well in ease of use, better than Apple's iPhone.

The reason that the Samsung Galaxy series phones are better than Apple's iPhone, there are two widely mentioned cause for our attention. One, most people think of the Samsung Galaxy series of Android phones more versatility, this versatility is reflected in the phone itself, is also reflected in the features and accessories. Another point is that people think the transfer and share files on the Samsung Galaxy series phones than Apple iPhone much easier.

In the level of brand awareness, we all think that the Apple products and Samsung products compared to design more compact, easy-to-use, use the product level, the Samsung Galaxy series phones turned unexpectedly beat Apple's iPhone in usability on the better.Samsung AA-PB2NC6B battery

Therefore, when we look back at the time of the survey, we can suddenly awoke, Samsung Galaxy series phones, especially among flagship phone (such as the Samsung Galaxy S4) has posed a very serious threat to Apple's iPhone, because Samsung Galaxy can not only achieve a richer interface custom settings, functions, and to use than the iPhone, more convenient and simple.

While most people still think Apple's style is more concise than the Samsung, but it has little practical significance. Naxigeer +, a survey report of the Gaelic consultant report of 94 multinational companies in 25 industries worldwide Home concise degree of analysis ranked Google doing my part to win the first the position of the name, Apple ranked fifth, Samsung did not even squeeze into the top ten, came in the fourteenth. However, this does not change the actual use of the process, people think that the fact Samsung Galaxy series phones are easier to use than the Apple iPhone.

Of course, not everyone is able to recognize the results of the final survey. Foreign well-known technology media CNET questioned a people can not be ignored. CNET's Chris Matyszczyk said the survey showed the actual situation is difficult to be fair, because first of Samsung Siegel, one of the + Gaelic consultant customers, and Apple is not. Second, the attitude of the 400 respondents is not enough to explain the problem, and their preferences can not be common. Because hundreds of millions of smartphone users worldwide, age, gender, geography, personality and other factors may decide smartphone habits, so as to interfere with the final results of the survey.Samsung P50 Series Battery

In the final analysis, the ease of use of the product can really affect a consumer's final purchase decision? To some extent, I think the answer to this question is yes. When I'm ready to buy a newer, better digital products to replace obsolete in my hand, or would like to purchase something new gadget when I will, of course, looking for those who use it more simple, do not read the instructions, no fee too much time on things that can easily get started. As for the back to select Android devices or iOS devices up, I think it will never be the only answer. Done because both in their respective fields are very good, but also very easy to use, but they are a slightly different design characteristics and development direction. Samsung R510 Series battery

Then again, not everyone has obsessive-compulsive disorder "simple" pursuit.

IDC said the blame fell 14% Windows 8 in the first quarter, PC

International reported: IDC today released a report that, in the first quarter of this year, global PC shipments fell 14%, far exceeding the previous 7.7% decline is expected, while a record the biggest drop since 1994.

Ok, you can go to sleep, and the notebook will automatically shut down after the end of the discharge. Thereafter, the

Power plug for laptop charging, attention must be completely filled and then boot, then the power scheme is restored to its original setting. This method is recommended to use the same friends of the new machine, the general lithium batteries in before it is put into use, the best according to this method to do 2-3 times, can be the maximum possible Asus K72J battery work optimal performance.

Apple's focus on the laptop's wireless charging

 
Recently, Apple submitted a patent --- laptop wireless charging function.

Qi (the world's first drive wireless charging technology Organization for Standardization) Wireless Power Consortium launched wireless charging standard that has been in existence for many years, has two characteristics. First, as long as there is a Qi logo, you can use Qi wireless charger charging. Second, it tackled the versatility of wireless charging technology bottlenecks in the near future, mobile phones, cameras, computers and other products can be charging with Qi wireless charger may provide for large-scale application of wireless charging. Moreover, this state-of-the-art technology, already by Sony and Samsung and other similar high-profile brands, each applied to their products.

Apple CEO Tim Cook said Apple application of this new patent by the U.S. Patent and Trademark Office called Wireless Display for Electronic Devices (wireless electronic device). As we've seen ASUS Wireless series computer. Apple's new patent means that, not only with the wireless display technology, and it will also have wireless charging function.

As we all know, Apple's various products have a different name, do not know in the future, when electronic devices with wireless charging function is released, Apple will give it a kind of call.
