How much do you know about the maintenance of mobile phone batteries?

1. Develop good habits, don't wait until there is no electricity to recharge, and don't continue to overcharge for a long time. Lithium ions like to shallow and shallow. Of course, for a normal user, it is very difficult to remember when to charge or turn off the software and other power-saving operations.

2. After the “fast charging” phase is completed, the charging has just completed about 80%, and the battery has a large charging space. In fact, the lithium-ion battery has two processes of “continuous charging” and “turbulent charging”. Use third-party battery management software to monitor the state of charge of the battery, allowing it to play a bigger role at critical times.

3. In fact, usually develop good electricity habits, and turn off some unnecessary software in time to save power. For example, turning off WiFi, Bluetooth and other devices without a network can also extend the standby time.

4. Many times, when the phone prompts low battery, the power is often quite low. If you continue to use it, it will easily cause excessive discharge, which has a great impact on battery life. Kingsoft Battery Doctor can customize the low battery reminder and intelligently switch the power saving mode.

5. At present, almost all mobile phones use lithium-ion batteries, there is no memory effect, there is no need to charge for 12 hours. In addition, excessive charging and discharging of lithium-ion batteries can cause permanent damage to the positive and negative terminals of the battery. Excessive charging causes excessive lithium ions to be embedded in the negative carbon structure, which causes some of the lithium ions to be released again, shortening the battery life, and also has safety hazards.

6. The whole process of mobile phone battery charging includes three stages: fast charging, continuous charging and trickle charging. After the first two stages, although the system power showed 100%, the battery did not actually reach saturation. At this point, the remaining capacity can only be supplemented by a small pulse current, which usually takes 30-40 minutes. After all three phases are completed, the battery can truly reach a good state of saturation.

7. In order to prevent the user from overcharging and causing accidents, the mobile phone battery adopts the design of the overcharge protection circuit, that is, the charging process is automatically terminated after the charging is completed. However, the battery will start the self-discharge process at the same time, causing the power to drop; after the power drops to a certain extent, the charging is started again, and the discharge-charge cycle is continuously performed. However, if it is in a high pressure state for a long time, it will have a negative effect on the battery and cause crystal precipitation, which not only shortens the battery life, but also has potential safety hazards.

8. The use of mobile phones while charging and other actions can cause damage to mobile phones, people and batteries. Because the voltage of the mobile phone battery when charging is higher than standby, if the call is made at the same time, the voltage at the moment of talking or connecting to the network will be many times higher than usual, which will cause the mobile phone to malfunction; secondly, the mobile phone when charging The radiation is also higher than usual.

9. Use your phone as little as possible when charging. In addition, the lithium-ion battery does not need to worry about multiple interruptions of charging, so when you need to make a phone call or play a game, you can disconnect the power. Normal use, but do not charge in a bad charging environment, unstable voltage will cause damage to the battery.

10. Lithium battery does not have memory, and likes to charge shallow, it can be used as needed. However, if you are unable to fully charge the battery under unintended circumstances, it is very likely that there is a problem with the charger or the battery itself. It is recommended to repair or replace it in time to avoid danger.

11. Although the iPad charger is compatible with the iPhone, it is best not to mix it. After all, the iPad's charging adapter can provide relatively large power, and in extreme cases, it can cause damage to the phone's battery.

12. General original charger, nominal output voltage DC+5V, output current 1A; and the standard PC USB port standard output voltage is also 5V, output current 500mA, according to these data, as long as the computer is well grounded, the USB interface has no quality problems. It is completely feasible to charge with the USB data cable, but the theoretical charging time is one time longer than the charger charging, which is a "slow charging".
