How to use a new battery
new lithium-ion batteries are have electricity: the voltage is too low will affect its activity, and even give rise to protection circuits turn off the output lead to charge. If you receive the lithium-ion battery is low or even no electricity, then stored longer battery or self-discharge is too large.
New batteries at the factory with electric current of high-rate charge into polarization serious effects of bad energy, lithium-ion battery so the first three should be shut down at cell phone use natural (not repeated after the forced shutdown boot, may cause cell phone or battery protection, cutting off the output can not charge)card-ton recommendations use of phones charger original charge around 6-8 hours.

How to avoid battery failure can not boot
In fact, can not boot most of the battery itself is not a problem, because batteries are in use, there have been charging and over-discharge, caused by the battery protection circuit, cutting off the output caused by the battery. Avoid prolonged charging of the batteries used in automatic shutdown to avoid repeatedly forced boot and timely charge is the key to avoid such questions. |

Battery into the fridge to revive it?
Online tips have said let the battery back to life, as follows: put the battery wrapped with newspaper and then put into plastic bags, wrapped well Add freezer for three days (newspapers can absorb excess moisture); three days later took out two days at room temperature decentralization; two days will charge the battery, fully charged up after the phone into test (estimated to save 80% ~ 90%).
In fact, the method can only be frozen because of the individual active substances caused Overcharge battery loose generate the role of chance, while the open-circuit plate corrosion, aging active substances metamorphic transformation,card-ton Think they did not have any effect. |

Answer the call when the echo phenomenon
From any telephone, including mobile phone, has a "side tone" of the problem:
At receiver heard their own voices. The reason is that phone calls are in the four lines: the transmitter and receiver of the two lines, but outside the system are second-line, mobile phone, too, must drive the need for second, four-lane conversion. Theoretically, if the "outside" of the impedance and machine "balanced network" exactly the same as the impedance, it does not produce the sound side. But the telephone line impedance of each user is different, phone balance network impedance can not be completely the same lines, and too complex balance network is not the economy, is impossible to eliminate the sound side. Mobile is also similar. As long as the size of the sound at the side to allow the scope, it is considered qualified. |
