Cell Phone Battery Care
Mobile phones use rechargeable lithium-ion batteries. When the internal storage power is exhausted, it must be recharged to replenish the power supply. dump. A good charger and correct charging method can maintain long battery standby time and extend battery life. To go further, it can also protect your mobile phone. Regarding how to load, the following points are summarized:
1. Typically, the manufacturer will activate and pre-charge lithium batteries before leaving the factory. For example, Scud batteries will be activated before leaving the factory. Therefore, all batteries have residual power. The newly purchased cell phone battery is lithium-ion, so the first 3-5 charges are called adjustment period and need to be charged for more thane 14 hours to ensure that the lithium ion activity is fully active. activated. Lithium-ion batteries do not have a memory effect, but are very inert. They must be fully activated to ensure optimal results for future use.
2. Some automated smart fast chargers are actually only 90% full when the light changes. The charger automatically switches to slow charging to fully charge the battery. Do not charge the battery immediately. The power is turned off, it is better to give the battery some time to recharge, and then use it after the battery is fully charged, otherwise the use time will be shortened.
3. Lithium batteries do not need to be discharged before being charged, and they cannot be discharged. Currently produced lithium battery chargers do not have a discharge function. If the charging speed can bee adjusted, this is recommended. that you charge Try to use slow charging and reduce fast charging methods; No matter slow charge or fast charge, the duration should not exceed 24 hours, otherwise the battery may burn the cells due to the huge electron flow generated by long-term power supply. provide.
4. Many users leave their cell phones on while charging. During the charging process, the battery is discharged outward due to the use of the mobile phone and power is supplied inward due to battery charging. It is very likely that the voltage disturbance causes the mobile phone's circuit board to heat up. In case of an incoming call, an instantaneous reflux current will be generated, damaging the internal parts of the mobile phone.
5. Battery life depends on the number of repeated charges and discharges. THEs lithium batteries can be continuously charged and discharged about 500 times. After that, the battery performance will be significantly weakened. should try to avoid discharging all the remaining battery power while charging, otherwise as the number of charges increases, the battery performance will gradually weaken and the battery standby time will hardly decrease.
6. Do not expose the battery to high temperatures or intense cold. For example, during summer days, you should not expose your phone to the scorching sun or take it with you. an air-conditioned room and place it where the air conditioner blows directly. When charging, the battery generates reflux and it is normal for it to heat up a little.
7. If the cell phone battery has been left unused for too long, it is best to contact the cell phone maintenance department to request activation.battery. You can also use a DC voltage regulator yourself. To adjust the voltage to 5-6V, connect the battery in reverse with a current of 500-600mA. Note, release it as soon as you touch it, repeat it up to three times.Install the charger for “adjustment period” charging.
8. The longer the charging time, the better. For batteries without protection circuits, charging should be stopped once they are fully charged, otherwise performance will be affected due to heat or overheating. The method to calculate the theoretical battery charging time is: divide the battery capacity by the charger output current. For example, for a battery with a capacity of 800 mAh, the output current of the charger is 500 mA, then the. charging time is 800mAh/500mA = 1.6 hours. Of course, this is only a theoretical calculation of charging timecomplete. When the charger indicates that charging is complete, it is best to give the battery about half an hour to recharge. Lithium-ion batteries must use a special charger, otherwise they may not reach saturation and affect their performance.
The above points are for your reference. If you have better methods, you can share them.
What to do if the mobile phone battery capacity has decreased
If the user wants to extend the effective use time of the battery, in addition to ensuring quality charger, correct charging techniques must also be used. This is essential because a poor quality charger or wrong charging method will affect the usage time and battery life. Here are the charging tips compiled by the author:
1. Before the battery leaves the factory, the manufacturer activates and precharges itaged, so the battery has residual power. Some friends said that the battery is charged according to the adjustment period, but the standby time is still seriously insufficient. This is indeed a real battery, in this case, the adjustment period needs to be extended and then fully charged and discharged 3-5 times.
2. If the newly purchased cell phone battery is lithium-ion, the first 3-5 charges are generally called the adjustment period and must be charged for more than 14 hours to ensure the lithium-ion activity is fully activated. Lithium-ion batteries do not have a memory effect, but have high inertia. They must be fully enabled to ensure optimal performance for future use.
3. Some automated smart fast chargers only indicate that they are 90% full when the light changes. The charger will automatically switch to charginge slowly to fully charge the battery. It is best to use the battery after it is fully charged, otherwise the usage time will be shortened.
4. Lithium batteries do not need to be specifically discharged before being charged. Improper discharge will damage the battery. When charging, try to charge slowly and reduce fast charging; the time should not exceed 24 hours. Only after the battery has undergone three to five complete charge and discharge cycles will all the chemicals it contains be “activated” to achieve optimal usage.
5. Please use the charger from the original manufacturer or a reputable brand. For lithium batteries, use a special charger for lithium batteries and follow the instructions, otherwise the battery will be damaged or even dangerous.
6. Many users often leave their cell phones onduring charging. In fact, it can easily harm the lifespan of the mobile phone, because during the charging process, the circuit board of the mobile phone heats up at that time. external call, instant reflux may occur. Electric current can damage the internal parts of the phone.
7. battery lifeIt depends on the number of repeated charges and discharges. Therefore, you should avoid charging when the battery has residual power. This will shorten its lifespan. When the mobile phone is turned off for more than 7 days, the mobile phone battery should be completely discharged and fully charged before use.
8． Cell phone batteries all discharge automatically. When not in use, nickel-metal hydride batteries discharge to about 1% of their remaining capacity each day, and lithium batteries discharge to 0.2% ~ 0.3% of their remaining capacity each day. When charging the battery, try to use a dedicated socket and do not share the socket with the charger, TV and other household appliances.
9． Although the phone is within the network coverage area, it is no longer able to receive and make calls when turned off and charging. At this time, you can use the missed call forwarding function of the mobile phone to transfer the mobile phone to the landline around you to avoid incoming calls from being lost. This method is also applicable when the mobile phone is not within network coverage. area where the signal is weak and cannot be connected temporarily.
10． Do not expose the battery to high temperatures or intense cold. For example, during the dog days of summer, you should not leave your phone in a car to expose it to the sunburning or take it to an air-conditioned room and place; place it in a place where the air conditioner blows directly. When charging, it is normal for the battery to be a little warm, but it should not withstand the “suffering” of high temperatures. To prevent this from happening, it's best to charge at room temperature and not cover the phone with anything.
11. The nickel-cadmium (N
iCd) battery must be completely discharged before recharging, and the battery must be fully charged after recharging.
12． If the cell phone battery has been left unused for too long, it is best to contact the cell phone maintenance department to request battery reconditioning. You can also use a DC voltage regulator yourself to adjust the voltage to 5~6V and the current to 500~600mA and connect the battery in reverse. Note that you can relet go as soon as you touch it and repeat up to three times. After this process, use the original charger to charge during the "adjustment period".
13． The longer the charging time, the better. For batteries without protection circuits, charging should be stopped once they are fully charged, otherwise battery performance will be affected by heat or overheating.
14. Lithium-ion batteries must use a special charger, otherwise they may not reach saturation and affect their performance. After charging, avoid leaving it on the charger for more than 12 hours. When not used for a long time, you should separate the battery and the mobile phone. If you want to buy a cell phone, be sure to come. look at! .
You can try two methods: wipe the copper contacts of the battery with a clean, dry cloth andput it in the refrigerator for a few hours. This will activate the polarity of the lithium battery. new battery: Note: do not buy fakes, buy brand batteries, such as Scud, and pay attention to the capacity, about 1000MA is more suitable
