2, in normal use when the charge should be
In our forums, often see this as the number of charging and discharging is limited, so should the cell phone battery power used up as much as possible and then charge. But I find on a lithium-ion Latitude C600 battery  charge and discharge cycle test table, on the life cycle of figures is as follows:
Life cycle:> 1000 cycle life:> 200
DOD is the depth of the discharge of which the initials. Can be seen from the table, the number of rechargeable and about the depth of discharge, 10% DOD at the time of the life cycle than 100% DOD’s a lot longer. Of course, if the actual charge equivalent to the total capacity of the relative: 10% * 1000% * 100,100 = 200 = 200, which is the complete charge and discharge, or better than some, but in front of friends do say that some of the amendments: normal Under the circumstances, you should have a reservation in accordance with the remaining battery power and then run out of filling the principle of charging, but if your battery is expected in the first 2 days you can not adhere to the whole day, should start on time charge, of course, if you are willing to back A charger to the office and when Bielun.
And you need to charge in order to cope with the anticipated upcoming busy communications will lead to an important event, even if there are a lot of battery power over time, then you just charge ahead of time because you do not have a real loss “1″ sub-charge cycle life , That is, “0.x” times, but often this will be a very small x.
The remaining battery power and then run out of charge to the principle does not mean that you go to the extreme. And charging the same length of a widespread view that “as far as possible the cell phone batteries run out of power, it is best to use automatic shutdown.” This is only a matter of fact on nickel batteries, to avoid occurrence of memory effect, unfortunately, it is also spread of lithium batteries on this. It has been too low because the cell phone battery warning appears, do not continue to use the charge has been used in automatic shutdown of the case. The outcome of this case, the phone was in charge of the boot in and there was no response, had to give customer service overhaul. In fact, this is due to the Inspiron 700m battery  as a result of excessive discharge and led to the low voltage that does not have the normal charge of the boot and conditions.
Lithium batteries for mobile phones boils down to the correct approach, I lithium batteries used in mobile phone charging and discharging of the most important tips are:
1, in accordance with the standards and procedures, charging time, even before the three to do so;
2, When the phone prompts when electricity is too low and should start charging as much as possible in a timely manner;
3, lithium batteries do not need to activate the special method, in a normal cell phone use in lithium batteries would be natural to activate. If you insist on spreading the use of “three times before the 12-hour long activation charge” approach, in fact there will not be the effect.
As a result, all 12 hours long pursuit of the lithium batteries and rechargeable cell phone used in automatic shutdown, are wrong. If you are used to be in accordance with the wrong done, please correct in a timely manner, perhaps not too late.
Of course, cell phones and chargers to protect themselves and control the quality of a good circuit, for the protection of lithium batteries or have guaranteed. Therefore, understanding the rules of the charge is the key, in some cases also may make some concessions. For example, you found your cell phone the night before bed charge, you can also start charging before going to bed. The crux of the matter is that you should know what is the right thing to do, and not in accordance with the deliberately wrong to do.
8 Apple iPhone mobile phone battery life 675 days Thu, 26 Jul 2007 00:40:45 +0800 Apple iPhone mobile phone is really a lot of press recently, PC MAG and even an in-depth study about the Apple iPhone’s battery life. They believe in the best case, iPhone’s G5345  can only be 675 days.
The data was something like this. According to official documents show that Apple, iPhone mobile phone battery charge and discharge in full after the 400 could reach 80% of the total electricity consumption. After user feedback, iPhone an average of 30 hours a need to recharge, PC Mag is the result of precise measurement 34 hours (which is estimated for charging an average of 1.5 days). The Apple iPhone is fully charged, the time is 4 hours. In accordance with the best of the situation and at the same time to each battery charge after the loss of electricity is included in the calculation, the battery life is 675 days.
Even in the off-line program, enter their mobile phone to buy Apple’s iPhone will be able to arrive at the date of the date of the batteries need to be replaced
Some users have already released the iPhone to extend mobile phone battery life.
Upgrade to the latest software upgrade to the latest iPhone will allow more power.

3. At least once a month full charge and discharge your mobile phone iPhone, so the F5136  can be maintained at its best.
When you use the iPhone do not remember a time when mobile phone screen lock.

4.’s Not the best time to turn off wireless and Bluetooth.
Open the automatic brightness adjustment, this feature can help save power.
Turn off the music player’s equalizer settings. Can contribute to saving energy.

In 2005, Yue Hwa Chinese companies have successfully developed high-rolling white solar glass Latitude D620 battery  packaging products, while China built the first solar glass production line. To create the largest high-rolling white solar glass packaging production base, Yue Hwa Chinese companies to invest in construction 250,000,000 yuan with an annual output of 100,000 tons of glass packaging solar calendar, after more than a year of construction, the third-phase project All completed and put into Sony laptop battery  production.
