Overview：Rumors have been circulating that answering a phone while charging a cell phone can cause an explosion. Experts say this statement is untenable. If there is such a danger, the product will be installed a program that does not access the phone when charging. However, from a health point of view, the wires will limit the range of movement of users. When charging, answering the phone may keep users in one place for a long time, resulting in excessive muscle tension. Therefore, it is recommended that the power supply be removed before calling. When charging, don't cover anything on the battery, and don't put it on the bed to avoid fire. Common sense of correct charging methods for mobile phones
Rumors have been circulating that answering a phone while charging a cell phone can cause an explosion. Experts say this statement is untenable. If there is such a danger, the product will be installed a program that does not access the phone when charging. However, from a health point of view, the wires will limit the range of movement of users. When charging, answering the phone may keep users in one place for a long time, resulting in excessive muscle tension. Therefore, it is recommended that the power supply be removed before calling. When charging, don't cover anything on the battery, and don't put it on the bed to avoid fire. Common sense of correct charging methods for mobile phones
1. Before the batteries leave the factory, the manufacturers have activated them and pre-charged them.
Therefore, all batteries have surplus power. Some friends said that the battery charged according to the adjustment period, standby is still seriously inadequate. If the battery is a good battery, in this case, the adjustment period should be extended for another 3-5 times of full charge and discharge.
2. If the newly purchased cell phone battery is lithium ion
The first three to five charges are generally called adjustment period, and should be charged for 12 hours to ensure full activation of lithium ion activity. Lithium-ion batteries have no memory effect, but they have strong Sui dynasty. They should be fully activated to ensure the best performance in the future.
3. Some automated intelligent fast chargers are only 90% full when the indicator lights change.
After 90% charging, the charger will automatically change to charge the cell phone with a slow charging mode, so it is better to use the battery after filling, otherwise it will shorten the life of the cell phone.
4. Before charging, lithium batteries do not need special discharge, and improper discharge will damage the batteries instead.
When charging, try to charge slowly and reduce the way of fast charging; the time should not exceed 24 hours. After three to five cycles of full charge and discharge, the chemical substances inside the battery will be fully activated to achieve the best use effect.
5. Please use the charger of the original factory or reputable brand.
Lithium batteries should use special chargers for lithium batteries and follow instructions. Otherwise, the batteries will be damaged or even dangerous.
6. Many users often turn their mobile phones on while charging. In fact, this will easily damage the life of mobile phones.
Because in the process of charging, the circuit board of the mobile phone will be heated, at this time, if there is an external phone, it may produce instantaneous reflux current, causing damage to the internal parts of the mobile phone.
7. Battery life depends on the number of repeated charges and discharges, so we should try to avoid charging when the battery has surplus electricity.
Such charging will shorten the battery life. Mobile phones can not be turned off for more than 7 days. First of all, the battery of the mobile phone should be completely discharged, and then it will be used when the battery is fully charged.
8. Self-discharge exists in cell phone batteries
When not in use, Ni-MH batteries will discharge at about 1% of the remaining capacity every day, and lithium batteries will discharge at 0.2% to 0.3% every day. When charging batteries, use special sockets as far as possible. Do not share sockets between chargers and household appliances such as TV sets. 9. Although the mobile phone is in the network coverage area, when the mobile phone is powered off and charged, the mobile phone can no longer accept and dial the phone.
At this time, the mobile phone can be transferred to the nearby fixed telephone by using the unavailable transfer function of the mobile phone to prevent the loss of incoming calls. This method is also applicable when the mobile phone is not in the network coverage area or the signal is weak and temporarily unable to connect.
10. Do not expose batteries to high temperature or severe cold
For example, in a dog's day, you should not put your mobile phone in the car, exposed to the hot sun, or take it to the air-conditioning room and put it in the place where the air-conditioning is blowing directly. When charging, it's normal for the battery to have a little heat, but it can't keep it from suffering from high temperature. To avoid this, it's better to charge at room temperature and not cover anything on the phone.
11. Nickel-cadmium (NiCd) batteries must be completely dead before charging.
The battery must be fully charged after recharging.
12. If the cell phone battery is left unused for too long, it's better to apply to the cell phone maintenance department for a live treatment.
You can also use a DC constant voltage regulator to adjust the voltage to 5 ~ 6V and the current to 500 ~ 600mA to connect the battery in reverse. Note that once touched, it can be released and repeated three times at most. After this treatment, the original charger will be charged during the "adjustment period".
13. Charging is not the longer the better
When the battery without protection circuit is full, it should stop charging. Otherwise, the performance of the battery will be affected by heating or overheating.
14. Lithium-ion batteries must use special chargers
Otherwise, it may not reach the saturation state and affect its performance. After charging, it should be avoided to place the battery on the charger for more than 12 hours. When not in use for a long time, the battery and the mobile phone should be separated.
The above is the correct method of mobile phone charging, if your charging method is not correct, you must pay attention to correct it.
