How long should the phone battery be charged

Many people believe that the first three charges of the battery have to be fully charged for more than 12 hours, and the sales staff of mobile phones, including even the technicians of some mobile phone manufacturers, admit to making this method, which seems to have become a classic. However, this method is no longer suitable for lithium batteries, but is suitable for early nickel-cadmium batteries.

First of all, explain a noun: C is a representation of the nominal capacity of the battery against the current, such as the battery is 1000mAh capacity, 1C is the charging current of 1000mA, note that it is MA instead of MAH, it is 10mA.

The origin of 14 hours: the first generation of nickel-cadmium batteries need to be charged at a small rate, and it is generally recommended that the charging current is 1 10C, for example, if your battery capacity is 600mAh, then 1C is 600mA, and 1 10C is 60mA. Therefore, it takes more than 10 hours to fully charge, and for nickel-cadmium batteries, small rate charging is beneficial.

2. The current battery situation of mobile phones: mainstream mobile phones are basically lithium-ion batteries.

3. Knowledge of lithium-ion batteries: We only talk about capacity on the one hand. There are two ways to measure the capacity of a lithium-ion battery:

1C charge and discharge; Charging and discharging, no matter what charging system is used, should meet the standard. Because lithium-ion batteries are different from previous nickel-cadmium batteries, the high-rate charging of 1C is already acceptable, and it must be accepted. And if a 600mAh battery is charged at 1C, it should be fully charged in about 1 hour, and if the phone is directly charged this way (many are, 12-14 hours is nonsense.

In fact, for nickel-metal hydride electricity, the national standard has also stipulated the index of high-rate charge and discharge, and I will not talk about it now.

4. What counts as "activation"? The lithium-ion battery itself is "live", if the design capacity is 600mah, although I charge it for 2 hours, I will be full, and then discharge, I can get a capacity of 600mah, and the design capacity has reached it, what is the problem of whether it is alive or not? The technical supervision department implements the national standard, and the detection capacity is charged with 1C, and then put, and the capacity reaches the qualification once out of 5 times.

So use it normally, charge it normally, and use it like this from the new battery, without worrying about "not being excited".

5. Charging for 14 hours is to deceive yourself: direct charging with a mobile phone, about 2 hours is full, and the remaining time is the time of the "baking" machine, if there is an error in the charging control of the mobile phone (there are some), then it is the time to test the battery. After 14 hours of charging with a socket charger that doesn't work well (there are too many on the market), your battery will be greatly frightened before it even starts to serve you.

The lithium battery mobile phone can be used at any time for the first time, including how long it will be charged later, and there is no limit to the length of time, but try to avoid the overcharge and overdischarge of the battery, which is more conducive to the battery life and the operation time of the mobile phone.

1. Lithium battery wood has a memory effect, so it can be charged and used at any time;

2. Try not to use the mobile phone to automatically shut down before charging, over-discharge will affect the life and may not be able to activate again;

3. Unplug the charger after the battery is fully charged, and the end stage of battery charging is trickle charging, and the current is relatively small, which has a greater impact on the battery life;

4. Minimize the number of charges, an indicator of battery life in the industry is the number of cycles;

If the mobile phone battery is not fully charged, it will not cause any harm to the mobile phone, and users can use it with confidence.

1. Please pay attention to the following precautions in daily use:

1.Please use the official standard charger to charge the battery to ensure that the charging voltage is stable and meets the standard, so as to avoid affecting the battery use.

2.Theoretically, keeping the battery in the middle range (e.g. 30%-80%) is more helpful for extending battery life, thus:

1) After the phone is fully charged, it is recommended that you unplug the charger to avoid charging for a long time or being in a high power state for a long time to accelerate the aging of the battery, so as to prolong the battery life.

2) If the mobile phone is idle for a long time, it is recommended to turn off the mobile phone and charge it regularly to maintain about 50% of the battery. If the phone is not used or charged for a long time, the battery may trigger over-discharge protection, resulting in abnormal charging or failure to charge.

3.Too high or too low a temperature can affect your phone's battery life, so:

1) Please try to avoid using your mobile phone in an environment with low temperature, high temperature or large temperature difference.

2) It is recommended that you try to avoid charging and using it for a long time, especially in high-power operation scenarios (such as watching, playing large games, etc.), at this time, the heating of the mobile phone will intensify, and charging and discharging for a long time at high temperature will accelerate the aging of the battery.

2. Extend battery life.

1.Tap Settings > Battery > Power Saving Mode to turn on Power Saving Mode.

2.Optimize the power saving settings:

EMUI OS: Go to the Phone Manager app and tap One-Click Optimize to optimize the settings that can save battery based on the results.

EMUI and below versions: Go to Settings > Battery, click One Click to Save Power, the system will automatically help you find some functions that may cause power consumption, and you can manually select optimization.

It is best to charge the mobile phone battery before the capacity is not less than 20%, and recharging below 20% will damage the battery, resulting in a reduction in battery capacity and a shortened life. So more than 20% can be charged.

If you are using a vivo mobile phone, the mobile phone uses a lithium polymer battery, and you can use it when it is fully charged.

1. Don't wait for the power to run out before charging, over-discharge will have a certain impact on the battery, in serious cases, it may cause the device to fail to turn on normally, try to charge in time when the power is too low;

2. It is recommended to use the original charger and data cable for charging, non-original chargers may have various problems, which may damage the battery and reduce the service life of the battery;

3. When charging, try not to play while charging, at this time, it is easy to increase heating, easy to lose the battery, and shorten the service life of the battery;

4. After the charging is completed, please disconnect the power supply in time to avoid charging for a long time;

5. Avoid using the equipment in a high-temperature environment.

When you are in use, you can charge it when the battery level is less than 15%.

Don't run out of battery and recharge, this is very harmful to the battery. Also, don't charge it when you're charging, just charge it to about 80%.

Through years of technological development, lithium battery technology has been very mature.
