Just six months on the cell phone battery: Do not charge

Just six months on the cell phone battery: Do not charge

Just bought a new phone for six months, the phone battery is not used. Later, consulting mobile phone engineers, found that it is usually their own phone to charge the "wrong position."

After a 90, I am a cell phone control. Daily life, whether it is watching the news, listening to music, or shopping, eating, etc., are inseparable from the phone. It can be said that smart phones are really "one of the greatest inventions of the 21st century."

After get off work every day, Xiao Bian will charge the phone, not only while charging while playing, but also charge the phone overnight. Until the next morning, go out to work, will unplug the charging line.

Therefore, think of want to go, only to understand that all night charging damage cell phone battery, so now the cell phone battery is not used

In general, smart phones use lithium batteries. Charger, the charger current flows from the USB port, usually "soldiers divided into two"：

 1. Charge the battery current, for example, when the constant current 1A charge the battery;  2. To the phone inside the module (camera, LCD, RF, etc.) powered current.

First of all, will enter the trickle charge, then the  phone battery voltage is low to not boot, will trickle charge, charge current is small, the assembly damaged the battery.

Second, the charge will trickle charge into the constant current charge. At this point the current is constant, the charging current will reach 2A.

Finally, the final stage, into the constant voltage charge. 4.2V phone battery voltage is generally full, when the battery voltage reaches 4.15V close to full charge, the phone into constant voltage charge. The voltage is constant, the current gradually becomes smaller, the final current is zero, the voltage reaches 4.2V (or 4.21V depending on the model phone), the charge ends.

At the same time, I see online users answer, summed up several ways to affect the  phone battery life.

Over-discharge: cell phone in low power, the battery voltage is too low will automatically shut down. But if you restart, there is still power available. Automatic shutdown is a manufacturer of mobile phone battery protection mechanism, battery discharge will cause serious battery life damage, so the battery is too low, please charge.

Over-temperature: the phone battery temperature is too high will also affect the battery life. Frequent discharge of the battery will heat, in the actual use of the phone battery over-temperature, usually due to this cause. Therefore, you need to pay attention to the heat dissipation when playing a large game or running other power-consuming programs, and control the program running time.

Under-temperature: Lithium Battery When the battery temperature is below 0 degrees Celsius, charging is not allowed.

     Overcurrent: Using a high power charger to charge the battery can cause damage to the phone battery. However, manufacturers are now alarming when the charging current is too high. The worst case of overcurrent is short circuit. Short circuit may cause the battery to explode and burn, please do not try.

Every day use Tips to extend your ASUS B31N1424 laptop’s battery life
1.Keep the ASUS B31N1424 battery contacts clean: Clean your battery’s metal contacts every couple of months with a cloth moistened with rubbing alcohol. This keeps the transfer of power from your battery more efficient.
2.Do not expose the Li-ion B31N1424 battery to extreme temperatures. Do not leave your battery outside in the cold or in your car in the summer. Cold batteries can’t create very much power and hot batteries will discharge very quickly.


3..Avoid allowing your device to discharge completely. Constantly recharging a lithium-ion battery does not shorten the battery life more than normal usage would. Avoid letting it sit on empty for too long; instead, keep it charged-up if you can.

4.Keep vents clear – don’t put your ASUS batteries on a fluffy pillow or a cushioned service that will cover vents and trap heat.


5.Chargeable batteries will wear down quickly, when they are only charged for a short period of time. When the laptop is not in use, such as at bedtime, plug it into an outlet and leave it to charge until the battery power is full.

6.Don’t pack your laptop away in a backpack or other enclosed space when the ASUS B31N1424 11.4V battery is still warm, trapping the heat. A battery that is frequently hot to the touch will lose life a lot faster than a battery that isn’t constantly being stressed. Worst of all: if your laptop crashes or refuses to shut off properly, the battery can get extremely hot when packed away in your bag.


7.Defrag regularly – The faster your hard drive does its work – less demand you are going to put on the hard drive and your ASUS A400U K401L Series battery. Make your hard drive as efficient as possible by defragging it regularly.
      Choose a laptop battery to choose good quality, because the battery is too important for the laptop, and we can do for you is to provide preferential prices, reliable quality and excellent service.

How to buy a power supply

How to buy a power supply

      Power supply is an integral part of computer equipment and has a huge impact on your computer. It is considered the most valuable component of any device and the most important component that can cause it. This article tells you what you need to pay attention to when purchasing a power supply.

1.Determine the wattage you need.

Use a power supply calculator web page or software to help determine your requirements. Even better is to find a review of a similar system that measures power consumption. As that consumption is measured at the wall, multiply by the review system's power supplies efficiency to get the output. Don't purchase a power supply just above your requirements unless you plan not to upgrade the system. Purchase a power supply that will take you through your next few upgrades.

2.Determine the robustness of the power supply.

How well does the power supply handle changes in current? Although not a guarantee, there's a strong correlation between weight and quality: bigger components equate to a more tolerant, reliable power supply. If you don't care about noise, an 80mm cooling fan in the traditional place on the rear of the power supply may offer better value.

3.Research which connectors you need.

Higher-end models may only provide a 24-pin connector, and lower-end models may provide just a 20-pin connector. Typically, most Pentium 4 and Athlon 64 CPU-based motherboards will require a 20-pin ATX connector, while newer motherboards require a 24-pin ATX connector. Also, most power supply will have both a 4-pin and 8-pin auxiliary 12V connector for motherboards, and only high-end power supply will have one or more 6-pin PCI-E connectors for video cards.

4.Check the number of rails.

Just as your house's fuse box includes both a large main breaker and a smaller circuit breaker per circuit to ensure the smaller-branch circuit wires do not overheat, high-capacity power supply divide their output into multiple "rails," each with a smaller current limit. The relevant safety standard requires a 20A limit, which is quite generous, given that the wires are smaller than those used in your house to carry 15A. A cheaper alternative is to provide just enough rails to total the overall capacity, which makes it difficult to use all of a power supply's capacity.

5.Look for power supply with high-efficiency ratings.

And, ones rated under load temperatures, not room temperatures. Anything 80% and above is good. At 83%, approximately 17% of the wattage is lost as heat. Therefore, a power supply that may be advertised as a 500W power supply, will actually be drawing almost 600W at the wall. Efficiency drops over time and during the life of the power supply. A year-old power supply is most likely not capable of producing the same amount of energy it once did when it was new.

6.Get a modular power supply.

It will help eliminate extra wires to get in the way of cooling. Ignore the claims by PC Power & Cooling that modular cables create more resistance due to corrosion of contacts. The additional resistance is negligible.

7.Compare the amperage of each voltage.

A power supply wattage rating isn't conducive to determining amperage at any specific voltage. All power supply will have a sticker with their rated amperage at each voltage level. This information should be provided when purchasing a power supply from an online vendor and visible on the unit's retail box.

      Do not neglect the power of the importance of choosing a good power supply is one of the prerequisites for your more joyful work.
