The power bank can be charged once a day, so there is no problem.
At present, most power bank batteries use either lithium batteries or lithium polymer batteries which generally can be charged and discharged 300-500 times. In terms of usage recommendations, it is better to partially discharge the lithium battery than to fully discharge it, and try to avoid frequent full discharges. So yesterday I used it to 70%, today I charged it to 100%, used 70% again today, and I'm charging it to 100% tomorrow.
A charge cycle refers to the process in which all of the battery's energy is used from full to empty, then charged from empty to full. For example, a lithium battery only uses half its power the first day, then it is fully charged. If it's still the same the next day, it'si.e. if you charge it half and charge it twice in total, that can only be counted as one charge cycle and not two. Therefore, multiple charges may often be required to complete a cycle. Each time a charge cycle is completed, the battery capacity decreases a little. However, this power reduction is very small and the overall impact on usage is not significant.
When the lithium battery is fully charged and discharged, it counts as one cycle. This means that only one complete charge and discharge counts as one cycle. At present, the number of battery cycles is relatively high, and generally speaking, there are not many problems during the consumer use cycle.
Today's power banks are all lithium batteries, so there is no need to limit the number of charges because the battery decay periodLithium ries is very long.
The nature of lithium batteries that cannot be overcharged or discharged requires mobile power users to charge the mobile power once when the mobile power is not used for a long time to ensure that it will not be over-discharged due to self-discharge.
Secondly, many power banks have protection mechanisms, and the product process will be tested during the charging process. Such as overcharge protection, overpower protection, overdischarge protection, etc.
The cell phone has been used for 2 years and has been recharged several times. Should I replace the battery?
Here, we must popularize a point of knowledge.
The number of charging times for all batteries does not mean that if I charge it once, it will be one time less. This is nots the concept.
The number of charge times actually refers to the number of full charge times. For example, if you use the battery until it is empty and then recharge it, you will lose once. But if you only charge it after 50% use, it doesn't count.
The theoretical lifespan of lithium batteries is about 10,000 times. Simply put, if you run out of electricity and charge them every day, they can be used for about 30 years.
Lithium batteries will perform poorly at low temperatures due to their physical properties.
Inside the battery, between the positive and negative electrodes, liquid is used to connect them.
As it is a liquid, it must solidify. Although winter temperature will not cause it to solidify, it is more than enough to affect its performance.
Is it better to doride drones more or less
Under normal circumstances, the lifespan of a mobile phone lithium battery is about 500 charge and discharge cycles. One cycle means that the battery power goes from 100% to 0. If every day If the battery is used to 20% of its capacity and then recharged, this is equivalent to 0.8 cycles per day, and the life of the battery is almost the same in 2 years.
Although the battery can still be used after 500 charge and discharge cycles, the user finds that the power is noticeably insufficient. In the past, it was enough to recharge it once a day, but now you have to recharge it two or even three times a day. Although users can currently think of many ways to extend battery life, such as downloading battery optimization software or even finding ways to restore battery power. Unfortunately, the lifespan of lithium-ion polymer batteries is irreversible and there is currently no technical way to repair long-used cell phone batteries.
So when your cell phone battery is obviously not enough, the best way is to replace the battery. It is relatively cheap to replace domestic cell phone batteries. For example, the Xiaomi Mi 6, launched two years ago, the official original battery price is 59 yuan, plus the labor cost of 40 yuan, the total can be 59 yuan . be replaced for 99 yuan.
Considering that the performance of previous generation flagship phones like Xiaomi Mi 6 is still quite adequate, it is still very cost-effective to spend 99 yuan to "rebirth " battery. .
However, if you need to replace the battery of aApple mobile phone, the cost will be relatively high. Take the example of the iPhone 7 of the last two years. Apple's official after-sales price for replacing the original battery is 359 yuan. For iPhone X level and later models, the battery price can reach 513 yuan. . Although Apple officially has no labor charges for battery replacement, the battery price of more than 300 yuan is still quite astonishing.
So, some Apple mobile phone users will now try to replace the battery with a third-party brand. Nowadays, the batteries produced by some old battery manufacturers are no worse than Apple's original batteries, and the prices are much cheaper. You can usually buy a good third-party battery for around 100 yuan. If the user has strong practical skills, he can follow the teaching videos on the Internetto replace the Apple mobile phone battery itself.
However, it should be noted that most Apple mobile phone batteries are stuck in the fuselage with double-sided tape. Under normal circumstances, they should be heated with it. an air gun before you can successfully remove them. If you use tweezers or other hard objects to forcefully remove the battery, the battery shell may be punctured, causing an internal short circuit or even spontaneous combustion. Therefore, if you are not absolutely sure, it is best not to try to replace the battery yourself. You can choose to buy a third-party battery and go to a repair shop in the electronics market to replace the battery, and the price is. not very high.
My cell phone is a 6S and the battery was replaced around May last year.The battery status at that time was half a day. 100% battery in the morning, 40% left around ten o'clock. I don't dare to browse Weibo when I go out, and I can't watch Sister ** on TikTok. A power bank is essential. After I couldn't take it anymore, I went to Taobao Fujishima to replace the battery myself.
It is certain that Taobao's battery is not as good as the original one. Basically, battery performance starts to decline after about five months. 100% battery in the morning can last up to about three hours. afternoon clock. Now, for almost a year, battery life has been significantly reduced, with at least two charges per day...
Cell phone batteries on the market are now mainly divided into lithium-ion batteriesand lithium-ion polymer batteries. The batteriesOriginal batteries are generally lithium-ion batteries, while Taobao batteries are mainly lithium polymer batteries, and their performance is necessarily lower than that of original batteries.
Since its birth, the lifespan of a lithium battery has been determined - about 500 charging cycles. Charge cycle here refers to charging the battery from 0% to 100% and then using it from 100% to 0%. Once the number of charge cycles is exceeded, battery life will drop. Right now, it's time for everyone to replace their cell phone or replace their battery.
1. Lithium batteries are most afraid of high temperatures. Try to avoid charging and playing at the same time. There are many cases of injuries from explosions on the Internet; In addition, the charger cannot be universal and different rechargeable batteries may beand mixed. This will accelerate the aging of the battery.
3. The optimal state of the battery. The power of lithium battery is 20-80%. Remember not to charge it for a long time or only charge it when the battery is too low;
4. Try not to replace the cell phone battery by yourself. The replacement process will inevitably cause the battery to short circuit or leak, which is very dangerous. In mild cases it will burn the operator's hands and in severe cases it will explode. Make sure you pay attention to safety.

Generally, the purchase price of batteries is about 100-1500. Don't choose thosewhich are too much. cheap, because the quality is usually unreliable, and don't choose one that is too expensive. This is really not necessary because a cell phone that has been used for several years may not be worth hundreds of dollars.
I wonder if anyone has any good battery brands to recommend? Please leave your valuable opinions in the comment box!
First of all, let's not talk nonsense. If you want to continue using this phone, you need to replace the battery because you cannot keep the power supply on your body.
Current technology has increased the number of charging times of lithium batteries up to 500 to 600 times, which means it takes about twice to charge one new mobile phone from 100% to 80% per year approximatelyTime, it is estimated that most of us go through it daily. Meets daily needs perfectlyns.
Let's talk about my two cell phones. The first one was used for a year and a half and the battery was no longer durable, it could only last more than half a day, so I changed. the battery myself. The result The battery was replaced, but the screen was broken. I spent over 400 to buy a screen myself and replaced it.
The second one was just replaced three months ago, and this one has been in use for two years. After replacing the battery, the phone came back to full health. The standby time can be said to be comparable to that of the new official phone. You can play games for more than 4 hours. My cell phone was purchased in 2017.
The most important thing is that battery replacement has a lot to do with the cell phone. If your cell phone costs a thousand yuan and you have used it for two years, it is not worth spending 100 suadditional. yuan to buy a replacement battery, so we need to do a gender-price comparison.
If you are not skilled enough to change the battery, go to a mobile phone store to change it. It's better to buy the battery yourself, because the batteries from the mobile phone store are really not good.
No matter how many times you charge it, the key is to check the phone's battery status to see if it is normal. What type of cell phone health is normal? We can feel it:
iPhone X has been used for more than two years and the current battery status is around 86%. I will not replace the battery of this phone because it does not meet the standards given by the iPhone (the battery capacity is 80%).
When the battery is at 80%, the battery health cannot meet our requirements for mobile phonesbiles. We saw from the official website that according to the iPhone battery life regulations, about 80% of the battery cycles are about 500 times. Currently the battery needs to be replaced.
Actually, when we use the battery, if the battery power is more than 80%, we may not be so worried. In fact, in 2 years, depending on the battery under normal conditions, health may be poor. have It's completely below 80%.
Why do we value 80% so much? the reason is simple. In 80% of cases, on the one hand, the battery storage life will decrease; on the other hand, because the mobile phone will implement performance mode, like the iPhone, there may be a lag, so-called frequency reduction.
If you feel that your phone is stuck or has no battery, you can consider upgrading your phone.
1 It depends on the type of mobile phone you have and whether the battery consumption time is the same as before. I have an iPhone 6s and haven't replaced the battery in 4 years. I gradually noticed that the battery was becoming less and less durable. Sometimes I don't do anything after going to bed at night and the battery is reduced. by 10% the next day.
If you own an Apple phone, you can check the maximum battery capacity once it is fully charged by following the following steps:
1. Open the phone's settings phone
2. Select Battery
3. Select Battery Status
Then check that the maximum capacity of the batteries is 100%. I just replaced a battery this year. The battery that was used. It has 80% left in 4 years, which is equivalent to a full charge. Although it is listed as 100%, it actually only has 80% power. If it is below 85%, it is recommended to replace the battery.
The lifespan of most lithium batteries is around 500 cycles, including iPhone batteries. After about 500 times, the battery performance will decrease and the battery capacity will decrease very obviously. If you want to maintain battery life and experience, it is more appropriate to replace the battery.
If you charge a lot, the battery may have worn out more than 20% in less than 2 years, leaving less than 80%.
Unless you want to change your cell phone, I suggest that it is better to replace the battery, because insufficient battery capacity will seriously affect the battery life. Additionally, some batteries will expand, and after expanding, they may even press on components such as displays, causing extrusion issues. Of course, if it's an iPhone or other models, some space will be reserved in the battery compartment for the battery to expand. That's why a third party can put a bigger battery, because this bigger battery consumes the reserved space. .
It must be said that the battery is the most easily lost hardware in mobile phones, and its loss is irreversible, no matter how you flash the phone or how advanced the algorithm is , battery loss is. a loss.
Apple users can check your battery consumption with battery health information ~
Many brands provide after-sales service for battery replacement . I myself went to Meizu and Huawei for after-sales replacement. batteries are not expensive. The cheapest model costs a few dozen yuan, while the most expensive model costs more than a hundred yuan. This includesalready the labor cost of the master.
So, if you have an Android phone and you do not want to change your phone, then you can definitely go to an after-sales point to change the battery. The price is not expensive and you can restore. battery life, which is great.
If you have an iPhone, there's nothing you can do. The cheapest official after-sales service costs more than 300, and the most expensive costs more than 500.
Of course, you can also find third parties to replace it, including some e-commerce platforms that offer battery replacement services! The price is around 100-200, which is quite reasonable.
The frequency of battery replacement is determined by how often the phone is used and charged. Generally speaking, the charging and discharging frequency of mobile phone batteriesis 300-500 times, which means that a new cell phone battery needs to be replaced within one or two years. When should the battery be replaced? It depends on battery life. When we ask the battery detailsWhen reading the information, we can usually find that the battery life is a percentage, which represents the loss of the battery. Generally speaking, the actual capacity and design capacity of the iPhone can be queried through software. Battery life is the actual capacity/rated capacity value, and the resulting percentage is the current battery life. When the battery charge cycle reaches about 350-500 times, the maximum battery capacity drops below 80%, which is the standard when we need to replace the battery. Apple officially recommends that if battery life is inferiorabove 80%, we had to replace the battery.
For other brand mobile phones, you can check the battery status by downloading detection software.
When the battery life is less than 80 %, the battery can still be used, but the endurance will be greatly reduced, unexpected shutdown may occur when the battery is low. So the battery life is less than 80%, which indicates that we need to replace the battery.
The mobile phone has been used for 2 years. The need for battery replacement depends on battery performance. Since ordinary users do not have professional equipment, they can evaluate it based on battery life.
Affected by the frequency reduction incident, Apple added a battery health option to the iOS system. According to official data from Apple, the battery should be replaced when its health drops below 80%.
Therefore, by checking the battery health, you can assess whether your iPhone battery needs to be replaced. My iPhone 8 Plus battery health is still at 85%, battery life is still good, and there is no need to replace the battery at this time.
Since most Android phones do not have the function of testing the battery status, you can judge whether the battery must be replaced depending on its lifespan. Under normal circumstances, the battery life of an Android phone is around 24 hours, and for heavy users, it is only around 15 hours.
In the system power options, if you find that the battery life is more than 20 hours, there is almost no need to replaceplace the battery. For my Android phone, the battery health is within the normal range.
Of course, the need to replace the cell phone battery can also be assessed based on the usual battery life. If you feel that your phone's battery life is significantly shorter or that the battery charge is diminishing too quickly during normal use, this is evidence that the battery needs to be replaced.
If the subject's cell phone has been used for two years, the battery is indeed not very good. After two years, it has been charged almost once a day, and it has been charged almost 600 times. battery life has been practically exhausted. Second, there is still use. During the process, charging and using mobile phones, etc., still cause a lot of battery loss.
Thus, the replacementof battery depends on the type of mobile phone the subject uses if he or she uses an Apple mobile phone.Or if it is a flagship model of domestic mobile phones such as Huawei, Xiaomi, OPPO, vivo, etc. , you may consider replacing the battery. For some sub-headlight models, it's not worth it. of cell phone is there, and battery replacement is also a cost, and Android There is a common problem with cell phones after long time use, they will become slow. After two years, there are very few cell phones. it can still work without problem.
After checking, the official battery replacement price of the above brands is roughly around 80-150 yuan. Apple may be slightly more expensive. You can check the price on the official website of each brand, or you can do so. choose some third-party websites (such as Suning.com, etc.) that also offerbattery replacement services!
The subject can refer to the suggestions below and consider them holistically!
If your cell phone battery has been used for two years and you want to continue using this phone, I recommend replacing the battery.
Because during these two years, as the mobile phone battery continues to be charged and discharged, the battery life will become shorter and shorter, and the energy storage will not will not correspond to the reference value. The battery capacity will decrease and consume power more and more quickly. At this point, it is recommended to replace the battery with a new one. to improve the situation of excessive energy consumption.
More cycles are better.
The number of drone battery cycles refers to the number of charges and discharges during the life cyclee full battery life, which is similar to the concept of battery life. This value is one of the quality indicators of rechargeable batteries and can also be used to assess the condition of used batteries. Nowadays, drone batteries mainly use lithium polymer batteries, and the cycle number of mainstream batteries is generally about two to three hundred times.
As the battery is used, the number of cycles continues to increase, the internal resistance of the battery increases, the activity of the chemical materials inside the battery decreases and the battery capacity decreases accordingly. When the number of cycles of the drone battery reaches the rated value, it means that you should seriously consider replacing the battery with a new one. Of course, this value is only an estimate obtained by the manufacturer in an experimental environment. If theambient temperature is high, if the battery is frequently overcharged and discharged, or even stored and maintained improperly, the battery may not reach the number of cycles specified by the manufacturer and will be discarded.
