How do I distinguish between mobile phone battery is fully activated

1, the battery charging speed is very fast, more than 1 hours or even less than one hour show the amount of charge had reached 100%.

2, charging up to 100%, the unplug the charger plug, plug in after the show when you charge the amount dropped to 50% -80%.

3, charging up to 100%, the boot display the amount of  Lenovo Laptop Battery, and under the age of cells, that only 3 or 4 cells.

4, mobile phone battery cell before 2 or 3 cells very durable, and then a few grid cells than in the previous durable.

There’s one of four kinds of cases, indicating that mobile phone battery has not been fully activated!

How to charge the battery:

1, first use the original or the reputation of a good brand of chargers, and try to use a dedicated outlet, do not share household electrical appliances such as charger and TV socket.

2, the battery factory, manufacturers have carried out active treatment, and conduct a pre-charging, the batteries have more than electricity. Lithium-ion battery 3-5 times before the charge commonly referred to as an adjustment period, more than 14 hours should be sufficient to ensure the full activation of the lithium-ion activity. Lithium-ion battery without memory effect, but a strong inert, should be given adequate activated in order to guarantee that used to achieve the best performance.

3, if the mobile phone battery but not been used to place too long, it is best to phone the maintenance department to apply to the IBM Laptop Battery for an activation treatment, after three to five times the battery fully charge and discharge cycles of its internal chemicals will be all “activation” achieve the best results. Can also be their own devices with a constant voltage direct current, adjusting the voltage of 3.7V, current of 780mA reverse battery connector. Note that the liberalization of touch, up to repeat three times, you can, and after such treatment, re-use original charger to “adjustment” charge.

4, the battery life determined by the number of repeated charge and discharge, in general, a battery can fully charge and discharge 500 times. So, should try to avoid battery power than when charging, it will shorten the battery life. Phone off for more than 7 days, should be first mobile phone battery is fully discharged, adequate electricity and then use.

5, charging should first be best to switch off a mobile phone. Because in the charging process, the cell phone circuit boards will be fever, at this time if there are external phone, you may create an instant return current to the phone’s internal parts damage

Cell phone standby time, so why would “shrink”? Perhaps relevant to the situation and the four mentioned below.

1. Use

The majority of users using EFR (the higher-bit encoding technology) to transmit voice, although the sound quality has improved, but it increases power consumption. Due to the loss of energy with the mobility size. When a user from one base station of the “cell” to another “cell”, the phone will follow the signal to detect the weak strong by which “cell” responsible for the cell phone, when the user is fast-moving state of the phone will always be a natural Repeat this kind of action, so the speed will be faster depletion of energy.

No longer is a GSM phone will all the information stored in the SIM card, if the hit cell phone out of fault or the replacement, the only incumbent, all the information card can be transferred.However, the information on the SIM card too, cell phones must from time to time to read the information on the card, so that the phenomenon of power loss will also appear.

2. Batteries

Many users when the battery is not filled with often used, the result is the phone will quickly run out of power, resulting in shrinkage of standby time. In addition the poor quality of the battery are also key issues, such as poor battery charge saturation is quite poor, life is shorter.Frequently used nickel-metal hydride battery is a progressive loss though, but the normal use for some time, this would reduce the effectiveness of the battery.

3. Environment

As the GSM mobile phone and base are among the 900MHZ or 1800MHZ wireless microwave transmission, therefore, are subject to weather, such as rain, thunder, typhoons and sunspots, etc. will affect microwave transmission, when mobile phones have to increase the power to maintain signal transmission, and therefore increased power consumption. There are a result of the signal outside the signal is better than indoors, so indoor best to use regular telephones, so that to reduce through walls, ceilings and other barriers to waste electricity.

4. This point can not be ignored, and that is improper maintenance of cell phone standby time will also cause the shrinkage

In point of contact between the battery and cell phone, there are some sheet metal, it is used for a period of time, there will be dirty or is oxidation, which would adversely affect internal parts mobile phone, this time consumption of electricity has also increased, so should always pay attention to hygiene is necessary

How to extend the use of mobile phone battery time?

Use of mobile phones, people are most concerned about in addition Huafei other is how to extend mobile phone battery as much as possible the use of time. To extend the use of mobile phone battery time, should pay attention to the following aspects:

Fast Charge: Some automated intelligent rapid charger when the lights change direction, that he was full of 90%. Charger will automatically changed to trickle charge until the battery is full, it is best used after the battery is full.

The battery memory effect: If the battery is a nickel-cadmium batteries, for long periods of complete charge and discharge, easy to leave marks inside the battery, reducing battery capacity, a phenomenon known as the battery memory effect.

The basic method of battery charging: different characteristics due to the battery, it should follow the manufacturers instructions manual method of charging. Standby standby mode, consuming cell phone battery. In case of fast charging, the phone must first shut down or remove the battery before recharging.

Regular elimination of Memory:Toshiba Laptop Battery nickel-cadmium batteries due to memory effect, must be regularly to eliminate memory. The battery is fully discharged and then re-filled.

Use power-saving mode: the majority of GSM phones with “DTX” non-continuous emission power-saving mode. In the quiet of the occasion should switch to the more quiet, a short phone ring tones. Select button turns off the display or lighting. Cold when the battery temperature is too low to avoid.

An instruction can be saving 30%

Just enter the following commands, you can make about NOKIA mobile phone to save more than 30% of the electricity. That phone’s standby time can be extended by one to two days.Interested? See the following method.

NOKIA mobile phone in your direct input “# 746,025,625″, which string values can turn off the SIM Kari CLOCK, in order to make the battery less power. According to test results show that the method can be saving 30 percent or even more! Want to know why?

In fact, “# 746,025,625″ can be said to be a SIM card in sleep mode sleep mode. The string of numbers do not back, because it represents “# sim0clock #” mean. Players only need to check each number in the phone keyboard corresponding to the number on it.

But be careful, just press each number once. For example, seven keys on behalf of S, one would anticipate that the press four times, but here, just press once. You only have to remember the keyboard corresponding to the location do not need to memorize that long list of numbers. At present, in addition to the older SIM card, the SIM card available in the market support this feature, it can substantially increase the standby time and talk time.

As for the subsequent years dormancy model? As long as your phone’s clock options will set it to display the clock, and enter the time, and then enter the date, we can successfully lifted.

Use of travel charge for mobile phones harm large

Sales of mobile phones currently on the market, the general distribution of travel quick charger, and some are also equipped with the Charger. Because a certain degree of price difference between the two, many users will only require allocation of travel charger, when the mobile phone battery needs charging, put the travel charger plug the phone directly to the battery charge. But we know from feedback from the actual maintenance of view, this failure may be caused by cell phone.

The performance of the general type of fault can not charge for mobile phones, seriously affected the normal use of mobile phones, and may even fail to boot.

From the mobile phone manufacturers to retain this function directly via their phones charging point of view, there should be a certain degree of technical support. However, damage to components of such failures on the analysis, generally charging current is too large, over the phone charging circuit caused by the load, so there should be two major causes of this type of failure: First, the current in many cities in China grid voltage is unstable, especially at night caused by a relatively high voltage; 2 is due to poor quality batteries, or battery power caused by too ruthless.

Caused by the failure of such charge, to mobile phone vendors and users have created a lot of trouble, such failure is attributable to human failure, is not part of the warranty, are also difficult to find authoritative answers.

Pairs of mobile phone users, the current is best to fast-charge as a temporary or emergency charging method, the use of seat Chong Chongdian as the main charging. Because the latter approach even if it fails, it will not cause damage to the phone itself.

How to extend mobile phone battery life

Due to the rapid decline in the cost of lithium batteries, the current mainstream mobile phones are all used in lithium batteries (or more high-grade). Main interest is to minimize the use of fast-charging, the other is filled with the best re-use and battery consumption to no boot recharge. However, the current lithium battery is already very mature, even if not in accordance with the method above, said that the use of the impact on battery life as before and no larger.

Use of mobile phones, people are most concerned about in addition Huafei other is how to extend mobile phone battery as much as possible the use of time. To extend the use of mobile phone battery time, should pay attention to the following aspects:

Fast Charge: Some automated intelligent rapid charger when the lights change direction, that he was full of 90%. Charger will automatically changed to trickle charge until the battery is full, it is best used after the battery is full.

The battery memory effect: If the battery is a nickel-cadmium batteries, for long periods of complete charge and discharge, easy to leave marks inside the battery, reducing battery capacity, a phenomenon known as the battery memory effect. This means that the battery seems to remember the user the daily charge and discharge rate and pattern, the course of time it is difficult to change this pattern and can not do a substantial charge or discharge.

The basic method of battery charging: different characteristics due to the battery, it should follow the manufacturers instructions manual method of charging. Standby standby mode, consuming cell phone battery. In case of fast charging, the phone must first shut down or remove the battery before recharging.

Regular elimination of Memory: nickel-cadmium batteries due to memory effect, must be regularly to eliminate memory. The battery is fully discharged and then re-filled. Discharge can put electrical or battery charger with discharge function, but also can take advantage of mobile phone standby standby mode, if the discharge can be to speed up the display and telephone keypad illumination lamp is turned on. To ensure that the battery will be full, in accordance with manual instructions to control the time, repeated charge and discharge two to three.

Use power-saving mode: the majority of GSM phones with “DTX” non-continuous emission power-saving mode. When the owner is not audible when the phone temporarily reduce the emission wave power. Results show, DTX power-saving mode can extend talk time up to 30% to 50%. In the quiet of the occasion should switch to the more quiet, a short phone ring tones.Select button turns off the display or lighting. Cold when the battery temperature is too low to avoid.

Mobile phone battery types: At present, mobile phone batteries are mainly nickel-cadmium (N & nbspicd) batteries, nickel metal hydride (N & nbspim & nbspb) three kinds of batteries and lithium-ion batteries. Nickel-cadmium battery can be a larger load current, for fast charging, drawback is prone to memory effect; nickel-metal hydride batteries has been the industry known as the “Green Battery”, is the mobile phone battery in quality, safe, reliable and conducive to environmental protection battery ; lithium-ion battery energy storage density, higher the weight of mobile phones can reduce the disadvantage of higher cost.
