Do you understand the "virtual power" of lithium-ion battery?

"Virtual power" is not a professional term, and is a particular name for one of the battery characteristics by ordinary users. Each battery has such physical properties: as long as the battery has electricity, the battery itself has tried to keep its nominal voltage until it totally loses energy.

A complete description of the phenomenon is: when the battery discharge is almost over, (electricity almost run out), but there is still a very small amounts of electric energy. At this time of the battery, if out of work environment (disconnect circuit), will slowly return to the nominal voltage, battery voltage, the lithium battery3.6 v).But this is a theoretical data, the actual situation will also lower. But this time is close to the nominal value of the voltage does not represent have electricity! When you access it work environment, because the battery discharge and did not have enough power, the working voltage of the battery will immediately fell to the lowest, and not work properly. This phenomenon is that people often say "empty electricity" phenomenon.

General battery appear such problems are mostly capacity is not big enough power adapter insert directly on the phone or long-term use of the "universal charger" battery. Whether you constant-voltage charge or power consumed by a constant current charge is the same! If does not limit current and constant voltage charging...The temperature of the battery will be very high, then explode (assuming power supply voltage of the battery voltage of 2.5 v, 4.2 v power supply resistance to 0 two hundred milliohm battery internal resistance, so that can achieve 8.5 amps charging current and general phone battery is not survive such a large current. And the new battery internal resistance is far below small make up two hundred milliohm set, this current will be larger.(some inferior universal charger in order to make the user feel it filling out of the battery is durable and deliberately turn off voltage to 4.3 V, the battery has been filled, and the charging current is too small for battery is also a kind of damage).

For lithium electricity pool increases with the increasing in charge rather than deep filling deep discharge can prolong the service life of batteries, battery capacity half of the charging current is also helping to extend the service life of the battery, so if you are not a good beginning ability DIYer with original charger good words.

Conclusion

In fact, we often say "empty electricity" can actually understand the cell phone battery is about to run out of time to show the "blip" phenomenon. Is not to say that when the battery is full time suddenly dropped 20% of electricity, appear this kind of circumstance of the comrades, don't use electricity to explain the problem, to change the battery!

The last small make up to introduce you to a few tips to keep the battery "lasting power" :

1, under normal circumstances, the battery cell phone use, there is a question of activity, the activity of how to activate the phone and make a battery in the most efficient state, became the use of mobile phones when should pay attention to an important question. And the activity of cells is associated with the temperature of environment, in general, mobile phone battery in - 10 ℃ to 50 ℃ can work normally. Therefore, we should try to avoid mobile phones in temperatures above 50 ℃ or below - 10 ℃ under the environment of work, otherwise, use a shorter time and life.

2, some people like quiet, do not want the phone ringing sound to interrupt yourself or others, so they will enable the function of the vibration of the mobile phone. Little imagine, the function of battery consumption is quite large, if you want to power under the same condition, make the phone work for longer periods of time, the author suggest that you might as well cancel the function.

3, mobile phones, by default, it is automatically started "luminous lighting", but the function and not bright, and the most demanding, so make it useless. Of course, if you urgent need luminous lighting function under the dark state, can according to the following set and operation: first of all to open the phone in the options menu, in which to choose "other Settings" menu item, and then open the "mobile phone Settings" option, and button set, in front of the automatic lock keyboard plus tick, then you can find luminous lighting is back!

4, the network signal does not exist or is extremely weak places the use of mobile phones, will consume battery power greatly, therefore in this case we should turn off the phone.

5, if you are a careful users, you will find, cell phone buttons in the press at the same time there will be a sound, the sound can say no ear, only hamper others "function", what's more, it also consumes battery! Therefore, we should firmly shut down "button sound" function, of course, if you prefer to show off, that is another matter.

6, if you are a budget, will think of it, that's as far as possible don't answer the call. It sounded, you may be angry shout loudly, you are in the "play" we (don't look at the following content is, affirmation is "gray").Wait a minute, small make up words haven't say that finish, small make up here refers to not answer the phone is said as far as possible using the "transfer" function, keep the cell phone automatically turn to the fixed telephone. Just think, in the case of a fixed telephone, still answer the phone, mobile phone more wasting electricity! Go to the machine on, save electricity, and reduce the radiation, why not do it!

7, The most important point of mobile phones is the function. Block those phones without good functions, so that it can save more electricity. For example, we should block features of "business prompt", "boot greeting", "animation menu" function and "rapid searching network", these functions will consume power of the battery.
