Hello, mobile phone batteries now use lithium batteries, so the mobile phone can be disconnected from the power supply without being fully charged. Therefore, unplugging the power supply without fully charging it will not affect the mobile phone.
To maintain the battery and extend its life, please refer to the following correct charging methods:
1. Do not wait until the battery is exhausted before charging: excessive battery discharge. The mobile phone will have a certain impact on the mobile phone, in severe cases, may cause the phone to turn on normally, so try to charge it in time when the phone tells you the battery is too low;
2. Use the original charger and data cable to charge the phone: non-original chargers may damage the battery and shorten its life;
3. the mobile phone while charging: Playing with the mobile phone while charging can easily damage the battery and shorten the battery life;? < /p>
4. After charging is completed, please disconnect the power in time: Everyone thinks that the first three battery charging times take more than 12 hours. In fact, this is a misunderstanding, because current batteries are all lithium batteries.
5. full cycle charge regularly: Use the battery to 5% then charge it fully.
Warm reminder: Batteries are consumables with a normal lifespan of 2-3 years. As the number of charges increases, the actual battery capacity decreases.

Why lithium batteries pdo they waste energy after prolonged use?
Up to 0.48 kWh.
10 A-hour 48V means it can be discharged for one hour at a current of 10A, so the total power is 10A*48V*1 hour=480W*1 hour=0.48 kilowatt hour , which is 0.48 degrees, but the battery isn't always empty when charging, so of course it uses less. And the battery will lose after prolonged use, so it is said to be at most 0.48 kWh.
Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M.S Whittingham proposed and began studying lithium-ion batteries.
The chemical properties of metallic lithium being very active, the treatment, storage andt the use of metallic lithium have very high environmental requirements. With the development of science and technology, lithium batteries have now become mainstream.

Precautions for charging lithium batteries
1 Place the battery for charging
< p. > There is some power left before leaving the factory, so the first charge should take a little longer. The battery should be charged in time after use, and should not be stored with power loss if the battery is left for more than two months. If not used, the battery should be fully charged.If the battery is left for more than 5 months, it must be charged and discharged once. Regular use of the battery and regular charging of the battery during normal use and long-term storage can ensure the best practical effect.e of the battery and extend its life.
2. Avoid charging at excessively high temperatures
If the lithium battery is used in an environment above the specified operating temperature, i.e. above 35°C, the power of the lithium battery battery will decrease. continues to increase. Reduction, meaning the battery doesn't last as long as usual.
If the device is charged at such temperatures, damage to the battery will be greater. Even storing batteries in a hot environment will inevitably cause corresponding damage to the quality of the battery. Therefore, trying to maintain a proper operating temperature is a good way to extend the life of lithium batteries.
3. Use the corresponding charger
In order to ensure the charging safety of the battery and ensure the life of the battery, the battery should use the corresponding chargercorresponding special width. Do not use a lead acid or other charger if the charger is lost or damaged.

How many times can a lithium battery be discharged and charged?
Lithium batteries begin to wear out as soon as they leave the factory.
This is due to the chemical properties of lithium batteries, i.e. the internal active materials will continue to reduce their activity over time and parts that gradually become inactive lose their function electrical energy storage. .
This is what we mean by battery loss.
I can give the poster some data on the duration and wear level of the lithium battery.
I have an old laptop. I bought it in 2007 and it is 11 years old. I use it almost every day,battery lost 41%. calculation, the average annual loss rate is 3.73%
The lifespan of a lithium battery is 500 charging cycles. For example: a lithium battery only uses half its charge the first day, then fully recharges. If it's still the same the next day, that is, charge it after half use and charge it twice in total. This can only be counted as one charge cycle.
The battery capacity will be reduced a little. However, this power reduction is very small. If the battery is of good quality, it can still retain 80% of its original capacity after several cycles. Many lithium battery products can still be used normally after two or three years.
But then again, products ultimately have a lifespan and lithium batteries also need to be replaced. The so-called 500 times means that the manufacturer has achieved approximately625 recharges at constant depth of discharge (80%), reaching 500 charge cycles.
Let's try againThe formula is clearer: 625×80%=500 (ignoring factors such as reduction in lithium battery capacity). In practice, due to various life influences, including the depth of discharge during charging is not constant, so "500 charging cycles" can only be considered for reference.
For mobile phones and other small electronic devices, you should immediately unplug the power cord (including the USB interface for charging function) after charging and continue to connect it, whether it is a laptop or a cell phone. be careful not to fully charge the battery. Also make sure to let the battery drain (automatic shutdown). If you go out, you can fully recharge the battery, but charge your devicesat any time if conditions permit.

Precautions for correct charging of lithium batteries: < p>1. Avoid charging at too high temperatures
If the lithium battery is used in an environment above the specified operating temperature, i.e. above 35°C, the power of the battery battery will continue to decrease, that is, battery power will not last as long as usual. Also charge the device if you are at these temperatures.
The damage to the battery will be greater. Even storing batteries in a hot environment will inevitably cause corresponding damage to the quality of the battery. Therefore, trying to maintain a proper operating temperature is a good way to extend the life of lithium batteries.
2. Avoid charging ats temperatures too low
If you use lithium batteries in low temperature environments, i.e. below 4°C, you will also find that the battery life is reduced. . Some mobile phones The original lithium battery cannot be charged even in a low temperature environment. But don't worry too much, this is just a temporary situation, different from using in high temperature environments. Once the temperature rises and the battery molecules are heated, the battery immediately returns to its previous capacity.
3. Use often
Life is in movement. If you want to maximize the performance of a lithium-ion battery, you need to use it frequently to keep the lithium battery's electrons in a fluid state. If you do not use lithium batteries frequently, remember to performcharge cycle of the lithium battery every month and perform power calibration, that is, deep discharge and deep charge.
