It can be replaced. The mileage will be much longer after switching to lithium battery. A 36V10AH lithium battery costs more than 1,000. It should be noted that when replacing lithium batteries, you should choose lithium iron phosphate batteries; other lithium batteries pose a risk of explosion. If you switch to a lithium battery, the charger must be replaced with a special lithium battery charger.
When you customize a lithium battery, you should pay attention to whether the voltage matches your original battery voltage and the capacity is not less than the capacity of the original battery. Lithium batteries with the same capacity as your original battery are lightweight, last longer than the original, have a longer lifespan, etc.

Lithium-ion polymer batteries in smartphones have a certain lifespan, and the battery is also the most prone to wear and tear in the mobile phone. Half the life of a lithium battery is calculated based on the number of cyclescharging and discharging. A full cycle from 0 to 100% and then back to 0. If the phone is charged every time its battery is half used, then that is considered a half cycle.
Therefore, if you use it lightly and charge your cell phone when 50% of the energy is used every day, the lithium battery may undergo a charging cycle and discharge in approximately 2 days.
According to lithium battery industry standards, the lifespan of smartphone lithium batteries should be at least 500 times, and higher quality batteries can last 700 times. Taking an average of 600 cycles and charging with 50% of its power each day, it can be used for approximately 1,200 days. It's been about 3 years.
Of course, just because the lithium battery's cycle count has expired does not mean the battery will be immediately discarded and unusable.Typically, after hundreds of charge and discharge cycles, battery life decreases significantly. The battery life of the mobile phone is only about 60% of its new condition, which means it may need to be recharged in less than half a day. And as the frequency of charging and discharging increases, the battery life will be further significantly reduced.
Therefore, the lithium battery of a mobile phone should be replaced within a maximum of 3 years if the battery life requirements are relatively high or if it is heavily used, then this time. maybe shorter.
Generally speaking, if you feel that the battery of your mobile phone is obviously not enough and cannot last even a whole day on a single charge, then it is time to replace the battery.Wait. Currently, the cost of rembattery placement of domestic mobile phones is relatively low. You can replace it with a new one for about 100 yuan, so the cost of replacing the battery once every two years is not very high. The battery cost of Apple mobile phones is relatively high. It costs more than 300 yuan to replace a battery for mobile phones before iPhone X, and more than 500 yuan to replace a battery for iPhone X and later mobile phones. In addition, the lithium battery capacity of Apple mobile phones is relatively small, the number of charging times is relatively frequent, and the service life is shorter than that of large-capacity domestic mobile phone batteries.
Regarding battery efficiency, I really feel strongly about it. Not to mention that I studied the principles of lithium batteries in my undergraduate degree,just talking about the cell phones I've used. , basically I changed the battery, so I will sort the battery life corresponding to the cell phone brands on the market:
Apple batteries have a time point, that is- that is, iPhone7 includes the previous products and the products after 7. Although they are all produced by Massey Huizhou, but due to the different consumption of the system after 7 (adding wireless charging), the duration Battery life has decreased significantly and is not durable. Basically before 7 the usage is 1.75 connecting to the. computer or check the cell phone battery. Battery life is about 88% in about 1 year, which is normal after 8 years, of course this is related to usage habits, but 88% is the bottom line. If it is below 88%, it can be replaced.
Why should I get rid of Samsung? IRepeat, just talking about regular mobile phones, Android still consumes more power than Apple? , which is why they are all above 4,500 mAh. The second reason is the widespread application of Android's fast charging technology. Until now, any fast charging will damage the battery life of the mobile phone, so it is recommended to use Android mobile phone batteries. be replaced after one year
Why should I remove it separately? It's not special because it explodes. The main reason is that the Samsung battery is freezing. Batteries have complex manufacturing processes, but they are safer and have more security. a longer lifespan. Therefore, Samsung's mobile phones have better battery life, which is basically the same as Apple's, which is about one and a half years. It is one of the few Android devices to extendbattery life at high power consumption!
Mobile phones on the market now use lithium batteries. Under normal circumstances, cell phone batteries are very durable as long as the cell phone you buy is not substandard or second-hand. hand, it will generally It is no problem to use the cell phone to eliminate it.
Lithium batteries have one characteristic. Under normal conditions, the charge and discharge cycles of lithium batteries can exceed 500 times. Many people have a misunderstanding. According to this calculation, if you charge it once a day, won't the battery be useless in less than two years? In fact, this understanding is wrong. Charge and discharge cycle refers to cyclic charging. According to most people's current usage habits, the mobile phone will be charged when the battery is about 50%. According to this calculation, it will be charged by 50% to 50%. 100% for you today. After using it, it will be charged 50% to 100% tomorrow. These two charges are then considered as a charge and discharge cycle.
This kind of overly professional thing seems a little confusing, it doesn't matter, we can just settle the accounts. We use two days of charge and discharge as cycle cycle, then if the lithium battery which meets the standard can be charged and discharged at least 500 times, that is 2*500=1000 days, which means it can be used normally for almost 2 to 3 years.
In 2-3 years, judging from the current speed of cell phone replacement, we will have already replaced our cell phones before the battery is discarded.
So, for this type of normal use, the mobile phone will not involve battery replacement. The situation in whichThe battery really needs to be replaced is where the battery is damaged due to abnormal reasons and cannot meet our daily use of the mobile phone. Only then will we consider replacing the battery.
When the following conditions occur on your mobile phone, you should consider replacing the battery:
1. After the battery is fully charged, the mobile phone can only last 2-3 hours, this will seriously affect the use and the battery will need to be replaced
2. The battery cannot be charged normally, or the phone does it. does not turn on and off normally due to poor contact. At this time, you should check whether the battery is abnormal. If so, you need to replace the battery. The battery gets hot for no reason. It is recommended to check the phone as soon as possible.
In short, if you maintainGood charging habits When you normally use your mobile phone, you will rarely need to replace the battery. The reason why the battery needs to be replaced is basically due to some external factors causing it. the battery is not working properly.
Welcome to click the upper right corner to follow: "Pacific Computer Network", which will provide benefits from time to time.
Battery replacement is not calculated based on time, but based on the number of cycles.
The lifespan of a lithium battery is about 500 times, and a better battery will last about 600 times, from 0% to 100%, then the battery is exhausted, which is considered a cycle. But that doesn't mean that every time you're not full of tangles it's not a cycle, because there's always a transformation from chemical energy to electrical energy and then de electrical energy into chemical energy. So, as long as a chemical reaction occurs, aging will occur slowly.
500 cycles, charging once or twice a day, if the battery is smaller, it will take more than a year, if the quality is better or the battery is more durable, it will take about two years. This needs to be replaced.
Of course, some people charge and play with their phones all day, and their batteries wear out more quickly.
However, to be honest, if you really want to change the battery, you will not calculate it based on time, but based on actual use experience. The battery life of the mobile phone has visibly deteriorated. If the weather hasn't gotten colder recently or the system has been upgraded, the battery is getting old. It's time to change it now!
The battery is getting old. Replacedstop it with a better one. It only costs more than 100 yuan.The originals are a little more expensive, but if you go to quality-assured stores to exchange them, it will cost you more than 100. So if your phone can no longer respond to your needs, particularly in terms of autonomy, simply replace the battery. If you can get better battery life for over 100 yuan, what's the big deal?
How often should a cell phone battery be replaced? I think if there is nothing wrong with the battery and it is not expired, there is no need to replace it frequently.
Batteries are normal consumables and are the shortest-lived parts of mobile phones, because our mobile phones constantly consume battery power. Nowadays, people use mobile phones and battery more and more frequently.e is often insufficient. Some people even charge twice a day to ensure that the mobile phone has power. Charging too frequently also reduces battery life. not durable, you need to consider replacing the battery.
Like many cell phones I've used, I've never replaced the battery. Basically I charge it once a day, if not used extensively, it can provide the power required by the mobile phone for a while. day. Replacing a cell phone is not a battery problem. In principle, the mobile phone is replaced after more than two years of use. The big brand cell phones we buy have no quality problems. The battery should last 1-2 years. A cell phone will be obsolete after about two years, so there is no need to replace the battery frequently. As for cell phonesue we currently use, the battery and the case are integrated and it is not recommended to replace the battery.
If our cell phone battery has been used for a while and has problems such as insufficient power, heat, longer charging time or charging failure, it means that There is a problem with the battery. The phone is still very new and we don't want to use it. When changing your cell phone, you should consider replacing the battery. Pay special attention when replacing the battery, because cell phone battery explosion accidents are often reported in the news. For the sake of our safety and health, when replacing the battery, we should choose the original battery supplied by regular after-sales channels. Do not go to a roadside cell phone repair shop por cheap. If there is a safety accident due to battery quality issues, it's really not worth it.
We must use our cell phone battery in a correct and standardized way. When charging, we need to choose the original charger. Do not charge the cell phone while in use. will last longer.
Actually, this is a very simple but difficult question. The simplest thing is: if you feel that the battery is low, you naturally replace the battery! What does it mean the battery is dead? After using it for 2 hours, the phone will run out of power; if it has 100% power and stays on standby all night, but cannot be turned on in the morning, this is called battery failure! You can therefore replace the battery of your mobile phone as soon as you think that it is no longer sufficient!
However, it is a questionThis is relatively difficult to answer, because how do you know when to replace the battery? Indeed, sometimes we feel like we can still use it. After persisting for a while, we buy a power bank and charge it every day. We don't even know if the cell phone will work? in this case it is difficult for us to judge.
Let’s first understand a term: lithium battery! What is a lithium battery? Lithium battery is also called lithium polymer battery. This is different from the nickel-metal hydride batteries we used in the past. Ni-MH batteries have memory and must be discharged and recharged; Lithium batteries do not have a memory effect and cannot be over-discharged.
How do we calculate its lifespan? Usually we calculate the number of charge cycles of lithium batteries, for example 0-100%, ce which we call a cycle (100-0%, then 0%-100%, this process is a cycle), and the general charge cycle of lithium batteries is 500.
Remember: charging to 100% does not mean I have completed a cycle; usually when we charge from around 50% to 100% it doesn't count as a cycle; , next time we will use it at 50%, then recharge again. These two processes of charging and discharging are called a cycle!
So you don't need to worry, we charge it once and cycle after charging it 500 times, we can replace the battery! Actually, that's not true. After recharging it several times, the battery capacity did decrease, but its number of cycles was far from reaching 500 times. Typically, the battery has cycled 500 times (iPhone says battery capacity is 80%). As long as it does not affect the usabilityion, your battery does not need to be replaced!
What we need to do is:
It depends on the battery consumption of your mobile phone or the existence of conditions that affect your mobile phone use.
My analysis from the perspective of after-sales maintenance personnel shows that the average usage time of each user who needs to replace the battery is about 2 years. Most of them are Apple phones and most of the time for intensive replacement takes place in winter.
The batteries in today's digital devices are all lithium-ion batteries. There is no memory function, just charge as you go. No complete charging or discharging is required. Therefore, when the device battery is used for a period of time, it becomes a consumable product in itself, and the loss decreases. After this reduction, bare devicesAmericas, especially mobile phones, automatically turn off when the weather turns cold. Other cell phone brands also exhibit this phenomenon, but the proportion is relatively small.
Normal battery cycle usage is about 400 charging times, calculated once a day, or about a year and a half. This does not mean that the phone cannot be used at that time, but that the phone cannot be used at that time. the usage status is the same as before. Buying a cell phone will give you a completely different feeling when using it, so at that time you will wonder if the battery is dead.
You can also use testing software to test the battery status. For example, you can see the battery status in an Apple phone's settings. Each brand of cell phone battery wears differently and each useThe user uses the telephone to different degrees. So it depends on the symptoms that appear on your phone to decide whether the battery needs to be replaced.
Using the mobile phoneAfter using it for a long time, you will inevitably encounter such embarrassment. Whether you use your phone or not, your phone's battery level is decreasing at a rate visible to the naked eye. In addition, life is now inseparable from mobile phones, and the short battery life of mobile phones is a big problem. Especially when you go out or have an emergency, it is embarrassing when your phone suddenly runs out of battery, and it may also delay your work. When to change your cell phone battery? If your mobile phone has any of these problems, it will not work unless you replace it.
For iPhone users, it is relativelyIt's easy to determine if the phone battery needs to be replaced. According to Apple's official standards, if the maximum capacity of the mobile phone battery is less than 80%, it is recommended to replace the battery at that time. Due to increased charging times and aging of the battery, the battery life of cell phones is shortened. Additionally, iPhones have always been criticized for their short battery life, and battery aging further affects the user experience. It is common to recharge more than once a day.
If an iPhone's battery life drops below 80% within a year of purchasing and activating it, you can visit an official repair service to replace the battery for free. Android phone users and those who have not updated to iOS 11.3 or above can also seecheck if their cell phone batteries have aged by downloading third-party battery testing tools. If your phone's battery shows significant wear and tear, it means you need to replace it.
In fact, there is an obvious criterion to judge whether to replace the battery when your cell phone gradually starts not charging or the charging time increases by compared to the original 2. hours to three hours, it means that the cell phone battery has aged. Generally speaking, the number of charging and discharging times of mobile phone batteries is more than 500 times calculated by charging once a day, it can fully support for about two years. However, damage to cell phone batteries caused by partial or improper overcharging. Charging methods will be significantly reduced. Phone battery lifeHowever, the deterioration of the battery life of the mobile phone due to other reasons will also cause the illusion that the mobile phone battery needs to be replaced. Because the lifespan of mobile phones is too long, the latest system is not compatible with mobile phones, unwanted software runs in the background, etc., these are all factors that lead to a deterioration of battery life of mobile phones. Therefore, if the mobile phone battery is not durable, it is okay to self-check via battery software or estimate the mobile phone battery life.
The most reliable thing is to have your cell phone repaired and its power supply tested so that professionals can tell you what the problem is. Nowadays, cell phone batteries aret been used for some time. It is normal to replace the battery, so you don't need to worry too much. When choosing a battery, you should use original batteries if you have the capacity. When using third-party batteries, you should also pay attention to the choice of products from regular manufacturers. The security risks will be much lower.
Click here. normal use, the cell phone batteries are used. Under normal circumstances, the capacity will decrease to 80% after 500 cycles. A cycle charges and discharges once. According to our current usage frequency, if we charge and discharge once a day, it will last 500 days, which is equivalent to about one and a half years, and the battery will wear out.durable. Of course, if it is a big brand cell phone battery, the quality will be better, but if it is a small brand, the quality will be worse, ggenerally one to two years.
Do not charge less than 30% of the power, and charge 10% of the power once a year to maintain the battery charging memory. I used this to charge my Y66. It's been over two years and it's still like new
