Twelve notes about cell phone battery maintenance

Mobile phone battery maintenance methods The popularity of smart phones makes battery maintenance more important. The maintenance of the mobile phone can prevent the power consumption of the mobile phone to a certain extent, and save the power to the greatest extent. At the same time, good battery maintenance can extend the service life of mobile phone batteries; it can also prevent some accidents caused by improper use of the battery, such as leakage when answering the phone, overcharge and explosion. 1. Develop good usage habits. Don't wait until the power supply is fully charged, and don't wait for a long time to continue overcharging. Lithium ion likes to be lightly charged. II. After the fast charging phase is completed, the charging completion rate is only about 80%, and the battery still has a lot of room for charging. In fact, lithium batteries have two processes: continuous charging and trickle charging, so even if the phone is fully charged, it is appropriate to continue charging for 30 minutes without stopping the charging. 3. In fact, usually develop good electricity consumption habits, there will be some unnecessary software shut down in time to save power, such as turning off WiFi when there is no network, turning off 3g without WiFi, Bluetooth and other devices can also achieve standby time . 4. In many cases, when the mobile phone prompts that the battery is low, the battery is often quite low. If you continue to use it, it will easily cause excessive discharge, which will have a great impact on the battery life. At this time, you should charge or turn off the phone in time. At present, almost all mobile phones use lithium batteries, which have no memory effect. Do not charge for 12 hours. In addition, excessive charging and discharging of lithium batteries can cause permanent damage to the positive and negative electrodes. Overcharging causes too much lithium ions to be embedded in the carbon structure of the negative electrode, and part of the lithium ions can no longer be released, shortening the battery life, but there are also safety risks. 6. The entire charging process of a mobile phone battery includes three stages: fast charging, continuous charging and drip charging. After the first two stages, the battery is not really saturated, although the power level of the system shows 100%. The remaining capacity can only be replenished with a tiny current pulse, which usually takes 30-40 minutes. Only after these three stages are completed, the battery can truly achieve a good battery saturation state. Seventh. In order to prevent accidents caused by overcharging, the mobile phone battery adopts an overcharge protection circuit design, that is, the charging process is automatically terminated after charging. But the battery will start the self-discharge process at the same time, resulting in a decrease in power; when the power drops to a certain range, it starts charging again, and the cycle of discharging and charging is repeated. However, if the battery is in a high voltage state for a long time, it will have a negative impact on the battery, causing crystal precipitation and adhesion, which not only shortens the battery life, but also poses a safety hazard. 8. The behavior of using the mobile phone while charging will cause damage to the mobile phone, the person, and the battery. Because the battery voltage of the mobile phone is higher than the standby, if the mobile phone is connected to the phone and other operations at the same time, the voltage will exceed the usual many times in the current conversation or network connection, causing the mobile phone to easily fail; secondly, the radiation is higher than normal when the mobile phone is charging. Use your phone less when charging. In addition, the lithium battery does not need to worry about multiple charging interruptions, so you can cut off the power when you want to make a call or play a game. It can be used normally, but it still does not charge in harsh environments. Unstable voltage can cause damage to the battery. 10. Lithium battery has no memory, and likes to charge lightly, it can be fully charged. However, if the battery cannot be fully charged without your will, it is likely that there is a problem with the charger or the battery itself. To prevent danger, it is recommended to send it in for repair or replacement in time. 11. Although the iPad charger can be compatible with the iPhone, it is best not to mix them. After all, the power supplied by the iPad's charging adapter is relatively large, with a current of 2A, while the mobile phone is 1A, so it may cause damage to the mobile phone battery. 12. Universal original charger, rated output voltage DC+5V, output current 1A; while the standard output voltage of general PC USB interface is also 5V, output current 500mA, according to these data, as long as the computer's USB interface is well grounded, there is no quality problem. It is completely feasible to charge with a USB data cable: Some pictures and content of the articles published on this site are from the Internet.
