To extend mobile phone battery life, should pay attention to the following questions: when the network signal does not exist or is extremely weak, they should turn off cell phones. As far as possible to choose the network signal strong local call.

Optional power-saving mode

With an advanced GSM standard features, that is, most of the phone have a “DTX” continuity of the non-fired power-saving mode. In order to power, when the owner is not audible when the phone for the time being launched to reduce the power of radio. Experiments prove, DTX power-saving mode can be extended talk time up to 30% -50%.

In the quiet of the occasion should switch to static, short of ringing telephone.

Select button, or turn off the display lighting.

To avoid the bitter cold when the battery temperature is too low, or else time will be shortened.

The basic method of charging the battery

As a result of different characteristics of the battery, so manufacturers are required to follow the instruction manual method of charging. Standby standby, the phone battery is also expensive. If the rapid charge, the phone will be required to shut down or taken out later by a rechargeable battery.

Quick Charge

Some automated intelligent rapid charger when the lights change direction, that is full of 90%. Charger will automatically slow to change with full battery charge will be. After the battery will be full of the best, otherwise they will be used to shorten the time.

Battery memory effect

If the battery is a nickel-cadmium batteries, not long-term total charge, discharge, easy marks left in the battery, reducing battery capacity, a phenomenon known as the battery memory effect. This means that the battery seems to remember the user’s day-to-day charge, discharge rate and pattern, in the course of time it will be very difficult to change this pattern, do not substantially charged or discharged.

Elimination of memory on a regular basis

Nickel-cadmium batteries because of the memory effect, it must be the elimination of memory on a regular basis. The battery is fully discharged and then re-filled. Electrical discharge can be put to use or discharge of the functions of charger also can use the cell phone back-up stand-by mode. If you can speed up the discharge display and lighting of the phone keys to open. To ensure that the batteries can be filled in accordance with the instructions manuals to control the time, sufficient to repeat, the discharge of two to three times.

Mobile phone battery types

At present, mobile phone batteries are mainly three types: nickel cadmium (Nicd) batteries, nickel metal hydrogen (Nimb) batteries and lithium-ion battery. Nickel-cadmium batteries can be a greater load current for fast charging. The disadvantage is that the battery prone to memory effect; rapid application of the charge. The disadvantage is that the battery prone to memory effect; nickel metal hydride batteries, the industry has been referred to as “environmental protection batteries.” It is the cell phone quality, safe and reliable, and is beneficial to the environment of the cell; lithium-ion battery energy storage of high-density, you can reduce the weight of the phone. The disadvantage is the higher cost

First, activate the battery (for the first time to buy batteries used for a long time or do not use the battery)

The random distribution of notebook batteries for high-energy lithium-ion battery, for the first time in the use of pre-press method to activate the battery as follows: the initial use Li-ion batteries, the batteries may have little residual power, the need to give discharge and then recharge batteries . Shutdown in a state of charge.

The battery is fully charged, can be used. The first three to use battery power to use all finished another charge. Moreover, the charging time can not be lower than the charge for the first time. In order to ensure maximum battery is activated to ensure the efficient use of battery time.

The above-mentioned process is known to activate the battery. After three complete charge and discharge, the batteries can be used to normal.

Second, the battery initialization

The use of laptop batteries after a long period of time, gradually find that the actual use of the battery will discharge longer than the original time to reduce the number of discharge, which is the lithium-ion battery memory effect.

Can remove the battery to initialize memory effect. Initialization means will be full of battery power, the power to take to do, and once again full of the process. Follow these steps to complete the initialization time:

Ø Make sure the computer is turned off, and then connected to an external power supply charge.

Ø full power after boot. When the screen appears “Press <F2> to enter System Configuration Utility”, press [F2] open the SCU program, and let the computer stops there.

Ø unplug the power adapter, so that the computer continued to drive until the battery power and not far off.

Ø the power adapter connected to the battery is full.

Third, the use of the battery Notes:

• Do not short-circuit the battery

• Do not put batteries will be higher than 60 ° C environment

• Do not put batteries in fire

• Do not drop the battery or vibration

• Do not wipe with a wet cloth on the metal part of the battery

• Do not use wet hands or touch the battery either by immersion in water or other liquid

• Do not arbitrary demolition of battery

• Do not under the sun, the temperature next to the object or the source of fire near the place where the use of batteries or their charge to the

• the use of battery time, as far as possible will be used up before all the electricity charge and a charge of electricity will be full, not half way on the charge or discharge. This will keep your battery at its best.

• Do not charge and a separate storage batteries for more than six months.

NOTE:

1. Do not recharge in the process of Unplug external power supply.

2. Do not free to use non-machine-specific batteries.

3. If this is the first time the use of Lenovo notebook computer, or you do not use it for a long time (three weeks or longer), it must discharge the battery completely and then filled with electricity, in order to restore full battery power.

4. Regardless of whether the battery is installed in the computer, there will be the phenomenon of self-discharge (about 1% of the day, according to a slight difference between different models).

5. If you do not use a computer for a long time (more than 3 weeks), we recommend that you unplug the battery, the battery will be a separate storage (storage environment described above).

6. Lithium-ion batteries because of damage will pollute the environment, but also a certain degree of risk. Please do not throw away free. When you’re ready to deal with waste battery when contact with local authorities to find out that abandoned

7. If you can not remove the battery for a long time, but must have a battery power (to prevent cell damage led to excessive discharge), depending on the number of battery cells may be the length of storage, such as stored in a long time, it is necessary to charge the battery power of the More short inside the battery power is stored for a long time in order to prevent the lead to excessive discharge. (Where there is no specific quantitative targets, the electricity business that no restrictions should be a little more is better). From the notebook battery is charged on the factory out of consideration in this regard.

With the increasingly popular notebook computer, notebook computer on every aspect of the problems attendant in a variety of media, the most controversial of a number of laptop batteries to proper use, the article said that some laptop batteries is the use of personal experience, while others claim Expert guidance, all kinds of stories have, many argue.

From my years of study on the use of notebook experience:

1 argument: the activation of the new battery

1 point of view: we buy a new battery, there will be more than 3% of the electricity, the battery’s power than is used up, until the shutdown, and then charge an external power supply. Time must charge more than 12 hours, repeated three times to do in order to activate the battery.

View 2: battery does not need to carry out 10 hours of rechargeable battery to activate the activity of the normal charge-discharge method to activate.

Recommendation: agree with the second point of view, according to the information available indicates that the battery should be activated in the factory completed, the notebook battery factory with a bit of electricity to avoid natural wear and tear caused damage to the battery. The battery should be activated in the absence of the protection circuit of manner, with its own lithium battery circuit protection circuit, this circuit is designed to avoid over-charging and discharging of the battery, battery in a general, the charging indicator light to turn off time , On the battery charge is not into power, then you plug in the power plug on the face of rechargeable batteries to carry out what is the use? From the battery will be able to see the situation on the battery charge there, and teach you a simple way to be able to determine there is no battery during charging, the battery will have time to heat, when the battery is full after an hour (power Do not pull the plug), then you try the battery to see if the battery does not heat hot yet? The results must be cold, not because the battery charge and discharge status, of course, not heat. Notebook makers in the factory when the proposed new battery for more than 10 hours. This may be the words so that some users have had the first wrong, this writer’s view is that notebook makers should be taken into account some new users to use a new battery when not fully grasp the skills of charge, so that they can simply charge 10 hours, so it should be the business expediency.

Debate 2: Unplug the external power supply when the battery?

1 point of view: the use of an external battery power will be removed.

2 views: the use of an external battery power when not removed.

Recommendations: in fact the battery is removed, the conflict focused on the use of an external power supply when the battery is charging up the issue. To know that the number of battery charging and discharging a direct bearing on the life of the general set of lithium battery charge and discharge the number of fixed and charge only the number of 400-600, specially to improve the product but also 800 times, once for each charge on the battery Retired to step forward. The first point of view is nothing but fear the use of power, the battery will charge on top, not only to increase the number of charge and will have sufficient cause. The second view battery on a computer using an external power supply when it will no longer charge. In fact, these two viewpoints has its right side, but also the wrong place. This is because the views expressed by individuals, not a very comprehensive investigation, a lot of notebook manufacturers are now taking into account the vulnerability of the batteries and products to add to the protection of battery technology, and therefore different from the corresponding brand notebook batteries Charging different protection techniques, such as some large companies in this area very well, such as: the original IBM, Hewlett-Packard, Compaq, Toshiba, and so on. One of the most thoughtful consideration is Hewlett-Packard, the Hewlett-Packard laptop battery to discharge detection, only battery power in less than 95% of the time will automatically charge. This battery can play a good role in the protection, quite a number of other companies have to follow. Therefore, such as batteries, you do not need to use the time to pull down, because only when less than 95% of electricity when it will charge. But even then, if you are using the computer for a long time, or the battery will be removed to better notebook for a long time because the heat generated when running on battery to a certain extent of the injury. However, some other “brand” of notebook batteries, may not enjoy such treatment because it has not done inside the battery protection technology. I like the use of individual friends of a certain brand of notebook computer, a battery on top in the use of an external power supply certainly have to charge about electricity, because the battery when the store will have wear and tear can not be 100%, and as long as Is not 100%, with access to the power supply on the charge. Every time an external power supply on access to the equivalent of battery time, although only a small charge will be the time. Therefore, we proposed the use of the time according to their own machine case may be, look at notebooks statement, choose to use an external power supply when the battery is removed.
