Is it possible to change the battery for samsung a3. Let's change the battery with free diagnostics
On almost all modern phones, the battery replacement process looks the same. We will look at this work with step by step illustrations using the example of one of the smartphones. For all other devices, everything looks the same.
Situations in which a new battery is required are fairly standard and common:
- the phone is over a year old and it began to hold a charge badly;
- the smartphone turns off in the cold;
- the gadget turns off at 20-30-40 percent;
- when the charger is connected, the percentage of charge jumps;
- the device gets a full charge in just half an hour.
Basic steps to replace the battery
1. First, take out the SIM cards and memory card to separate the cover. Remove the back cover by first unscrewing the bottom bolts. The cover is usually either glued to the body of the phone or snapped into place. If the lid is glued, then we heat it up to 80-100 degrees and gradually detach it.
2. Inside the phone, a protective panel is attached to the bolts, which holds all the insides of the phone. We unscrew it and remove it.
3. Disconnect all cables, unscrew the remaining retaining bolt and take out the motherboard.
4. The old battery is attached to the factory tape. First, peel it off, then gradually make our way under the battery and carefully detach it from the case. The display cable and the board-to-board cable pass under the battery. If they are damaged, the display will stop working or the phone will stop charging.
What should be paid the closest attention at this stage:
- we handle all internal elements extremely carefully;
- we are not in a hurry when carrying out work, there is no need to rush here;
- carefully disconnect all the cables;
- before reassembling, make sure that the smartphone starts with a new battery
5. Glue double-sided tape on the inside of the case, glue a new battery on it. We press it tightly so that it holds firmly, since there are no other fasteners, except for adhesive tape.
6. Putting the phone back: insert the motherboard and fingerprint scanner, attach the protective plate.
7. Firmly insert the back cover into the grooves. The phone is ready! We wipe all surfaces with alcohol and give them to the client.
The new battery needs to be calibrated. Charge your phone overnight for at least 8 hours. Use your phone as usual the next day. It is not necessary to discharge to zero. Then put it on again until it is fully charged. This is called "battery calibration". It must be produced in order for your smartphone to use the capacity of the new battery to the maximum.

- The battery charges in less than 30 minutes and discharges just as quickly.
- After a slight blow or drop, the battery in the smartphone slightly swelled, which is well felt if the back cover began to move slightly away from the body.
- After getting wet or a strong blow, the battery in a3 2016 samsung swelled so much that the back cover detached from the case almost along the entire right side, while the battery is clearly visible.
- After being in a discharged state for a long time, the battery does not take charge and the smartphone does not turn on or boot, and even when charging it does not show signs of operation.
- Samsung A310 2016 reboots or turns off at 15-30 percent, while when the charger is connected, the smartphone does not spontaneously reboot or turn off at low percentages
To understand exactly what the problem is in the battery, you need to calibrate the battery in your smartphone. Quite often it happens that during operation the phone is charged and discharged incorrectly. That is, the device charges up to 20, then up to 35, a little more and a little more, and then the bell rings and again is removed from the charge. This is not correct. The device must be charged without interruptions up to 100 percent, and it must also be discharged, without trying to connect charging.
If, after the battery calibration procedure, the problem persists, or the battery is very swollen and does not hold a charge at all, in these cases it will need to be replaced with a new one. Now there are several proposals that can be roughly divided into 2 types: an original battery and a fake battery
Genuine rechargeable battery has the same characteristics as the battery installed in a new similar device. That is, the same capacity, the same controller and other internal parameters. In other words, a genuine battery will not just fail or swell without damage.
Fake battery has other internal characteristics and parameters. Most often, the capacity indicated on the back does not correspond to the capacity that it will show when testing at the hardware level. In other words, a fake battery will hold worse than the original, and there is always a chance that the battery will spontaneously begin to swell and bulge out of the case.
How to replace battery for samsung galaxy a3
Before proceeding to replacing the battery on the samsung galaxy a3, you need to disassemble it. Given that the new models of smartphones use an adhesive base, you will first need to glue it, and then proceed directly to disassembly. To carry out the first manipulation, you will need to slightly warm up the device from all sides. After that, you can already remove the module.
All tasks must be completed carefully and slowly. Having dealt with the screen, it is necessary to proceed to unscrewing the bolts. Care should be taken to ensure that none of the small details get lost anywhere. After completing the unwinding work, you will need to carefully remove the "filling" and turn it over with its reverse side.
There are also bolts there. They will also need to be unscrewed. As it is released, some parts of the phone will “fall off”. This is normal. Getting to the battery is not easy enough, so while the next final bolts that fasten the walls to the base in which the battery is clamped appear, you will have to disassemble almost the entire smartphone.
By loosening all the bolts, you can pry on the battery and remove it from the slot. At the end of the procedure, you can safely answer the question "how to replace the samsung galaxy a3 battery". In fact, if you wish, it is not difficult to do this.
Where to begin
Sooner or later, all owners of various electronic devices, mainly smartphones or tablets, are faced with the problem of quickly discharging their gadget's battery. Some users immediately contact service centers or shops, believing that the malfunction lies in some components, for example, the battery. Others try to solve the problem by installing various firmware or trying to modify the installed software. Still others immediately begin to scold the manufacturer and change the device with the hope that this will not happen again. In this article, we propose to understand the issue and understand how to do the right thing if your smartphone or tablet is quickly discharged. Let's start with the main thing - before you panic and take any action, you need to ask yourself three questions:
1 How long should my device last? A day, two, maybe a week? What time of work do I expect from it?
2 How often do I use it? Every five minutes or once a day? What if I don't turn it off at all? Or, on the contrary, I don’t use it?
3 What is the scenario for using it? Do I play games or listen to music? Or maybe I constantly hang out on social networks? What exactly do I use the most?
The answers to these simple questions will help us understand the situation and understand whether something really happened to our smartphone or tablet or something else.
How long should a smartphone or tablet run on Android
First, you need to understand that the operating time of the device depends on a huge number of factors, and not only on the capacity of the battery (this, by the way, is one of the most common misconceptions).
Factors that affect battery consumption:
1 Scenario of use. The more tasks you set for the device, and the more difficult these tasks are, the faster the battery will drain. If you play games with excellent graphics, watch videos, use the Internet or GPS, like to set the maximum brightness of the screen backlight - do not expect your smartphone or tablet to show battery life records, usually with this mode of use, it sits down in 3-5 hours.
2 The quality and quantity of applications used. Today the profession of a programmer is more popular than ever. Everyone wants to write their own application, get into the top downloads and earn the fame of a famous developer. In pursuit of these achievements, programmers write thousands of programs and add them to the Play Store or similar stores. However, not all users understand that the quality of written applications can be different, because not everyone who wrote these applications is really experts, or wants to benefit other people. A large number of applications are of poor quality or some hidden features that clearly will not benefit your device. For example, the application code may be with a bunch of errors that make the device constantly work and prevent it from "falling asleep", or have functions for collecting and sending large amounts of statistical data to third-party servers. As a result, the processor will operate at higher frequencies, consume battery power and constantly leak traffic with your personal data, which will lead to excessive heating and inefficient battery consumption. The number of installed applications also greatly affects the operating time, below we will explain why and invite you to make sure of this.
3 Technical condition of the device. All things invariably break down and become obsolete, the same fate befell electronic devices. Over time, the capacity of the battery decreases and some components may fail. As a result, battery life starts to decrease. The built-in software (operating system) can also accumulate errors that lead to unstable operation of the device, freezes, slowdowns, and rapid discharge.
4 External circumstances. For example, these include weather conditions (at low temperatures, the useful capacity of the battery decreases sharply; on a sunny day, the backlight should work at a higher brightness to improve readability) or the quality of third-party services and services (cellular reception level; Wi-Fi signal quality; correct data synchronization with third-party servers).
5 Device specifications. Engineering solutions may not always be successful. For example, if a smartphone has a large diagonal of the device, but a small battery capacity, then it will sit down in a matter of hours. But it is no coincidence that we put this factor in last place. In 99% of cases, all characteristics change proportionally (more screen or more powerful processor - more battery capacity), so the average operating time is always about the same. In addition, the technical characteristics include the characteristics of the components from which it is made. The point is that not all of them have the same energy efficiency and performance. The newer the device, the more energy efficient and productive components are used in it. This can be easily seen in the Samsung Galaxy line of flagship smartphones and tablets. With each new generation, the screen resolution increases, the processor power increases, additional functions appear, but the battery capacity increases only by a small amount of mAh (by the way, we will also explain why this happens a little below). However, the average operating time does not decrease, but rather increases. In particular, this is due to the use of more energy efficient components (the size of the components is constantly decreasing, and with them heating and energy consumption).
Summing up: answer the question: "My phone is discharged in so many hours, is this normal?" very difficult, you need to collect a lot of information. To better navigate, we will indicate the operating time in an average mode (per day: a couple of hours of music, an hour of Internet surfing, a couple of hours in navigator mode, 40 minutes of calls, messengers or mail in moderation), this is about one or two days. But remember that everything is individual.
How to increase the operating time of your Android smartphone or tablet
Now let's see how we can eliminate the causes indicated above, or at least try to reduce their impact.
1 If you honestly answered the questions above and came to the conclusion that you are not letting your smartphone or tablet out of your hands, then we have bad news for you. It is impossible to increase the operating time with such use, since this requires a completely new type of battery, which humanity has not yet invented. But do not despair, there is always a fallback. In your case, this is the purchase of an external battery, in which you can carry spare energy and recharge the main battery of the device. These batteries are available in different capacities, and you can easily find the one that is right for you.
In addition, I immediately want to answer a common question why Samsung did not make a standard battery with a larger capacity. The fact is that not everyone plays games, watches videos or surfs the Internet. Most people use their smartphone sparingly, do not load it with a lot of applications, and the standard battery is enough for them, for example, the author of the article uses the Galaxy S5 and lasts for two days. If a standard battery had a larger capacity, firstly, the dimensions of already rather big devices would be much larger (you can't put it in your pants pocket), and secondly, the price would also rise. That is why, with the help of additional accessories, we suggest increasing the capacity to exactly the one you need.
2 Let's take a look at what is important to know and understand when installing applications.
Every time you decide to install a new application, pay attention to its permissions... Permissions are a list of actions that an app will be able to do on your device after downloading it. The more permissions the application has, the more system resources it will use, and the more difficult it will be for the device to go into power saving mode (the so-called sleep mode), because the application can run in the background and will constantly wake it up, even if the screen of your gadget is off and nobody uses it. You can read more about permissions in our article.
Required control the number of installed applications, because, as we found out, each application has permissions, and if there are many applications, then the permissions increase significantly. If there is an unnecessary application - delete it, do not leave it in reserve.
Try to choose those applications that are written by famous authors, have been downloaded many times and have a high rating. Of course, this is not a guarantee of stability, but it significantly reduces risks. It is also useful to know that the functionality and stability of the application can not only improve, but also deteriorate when it is updated. It often happens that no new applications were installed on the device, but suddenly it began to discharge quickly. The problem might be a badly written update for some application.
To diagnose your device, you can use safe mode... It differs from the usual one in that only standard applications work in it, and all loaded ones are disabled and do not have any effect on the system. If the problem in safe mode disappears, you can safely conclude: downloaded applications are to blame. However, at the moment there is no tool that allows you to find out what exactly this application is, so they usually act like this: load the gadget in safe mode and check for a problem. If the malfunction disappears, then they are loaded as usual and begin to uninstall those applications that were installed or updated last until they find the culprit. By the way, you can try to do such a test: boot your device in safe mode, note the time that it will work on one charge, and compare it with the operating time in normal mode, we assure you you will be surprised. You can read more about Safe Mode in our dedicated article.
Also, the author of the article met user comments that pre-installed (built-in) applications are also to blame for the category. It is possible that there is some truth in this, but numerous experiments suggest that if there is an influence, then it is extremely insignificant. Moreover, the operating system is designed in such a way that the work of many applications depends on each other and their thoughtless removal can only harm the device.
Nevertheless, it would be dishonest not to tell about all the possibilities, so we are sharing "secrets" with you: some of the preinstalled applications can be disabled so that they will not affect the running system, i.e. they seem to fall asleep. You can see how to do this in this article. You can turn them back on if necessary.
3 Now let's consider which of the components can affect the operating time of the device. There are two possible reasons:
Battery - its service life is designed for a certain number of charge-discharge cycles. Useful capacity during use
begins to decrease until the battery ceases to hold a charge at all. That's why the battery needs to be replaced every one to three years (depending on the intensity of use). You can purchase original batteries at Samsung authorized service centers, branded stores, and partner companies. The required model can be viewed on an old battery.
In addition, there are several myths that are firmly entrenched in the ranks of users, so I would like to separately note the following: the battery can be charged as you like, you do not need to discharge it to zero, keep it on charge for 15 hours, and do not be afraid to use your device, nothing will happen to it.
The motherboard is the most important component of your device. It can have completely different damages, as a result of which the device can quickly discharge. Professionals are taught to understand these damages, therefore, if you are convinced that the problem is not in the battery or in something else, we strongly recommend not to experiment on your own, but to contact any of our service centers in our article.
Change your mobile operator if the coverage area does not suit you :)
What other tips can we give? There are few of them, but they are also very important:
Disable auto-sync of added accounts or configure it selectively.
Synchronization is the process of transferring various data from a smartphone to a server and vice versa. This data can be anything: new contacts, music, mail, photos, achievements in games, etc. When you are not using the device, it is in "sleep" mode, in which power consumption is greatly reduced. Synchronization works in the background, so you may not even notice how it "wakes up" the device. If this happens very often, the device may discharge much faster even if you are not using it.
If you tried all the recommendations in this article except contacting the service center, but nothing helped, then you need to reset the settings.
A factory reset is a reset of the device to factory settings, which erases all data, and with it, errors that accumulate in the device after active use. Factory reset is better prevention against errors that arise over time in the operating system and applications. This is especially noticeable if you use a smartphone or tablet after a reset without downloading a bunch of other applications to it at once. And especially it is important to reset after a software update (firmware). Not everyone knows, but the process of flashing on its own and in a service center is very different, which is why many people start to run out of battery after the update. This does not mean that the update is bad, it means that it was delivered not quite right. Therefore, we will repeat again: be sure to reset after the update, this will greatly reduce the likelihood of various troubles with your gadget.
You can only replace the battery for Samsung Galaxy A3 at a service center. A free courier will pick up the broken device. The technician will repair the battery and then return the gadget to the owner.
The service center uses exclusively original parts, including battery. This is important as a fake can malfunction and quickly deteriorate.
Changing the battery in this model is not easy. The manufacturer decided to make it built-in, therefore, if it breaks down, it is better to immediately carry it to the service, where engineers will repair the product and return it to working capacity.
The replacement process can be described as follows:
- The body is opened with a spatula. It will not damage the case.
- Retrieves an item.
- Checks the contacts responsible for connecting the power supply and the main parts of the smartphone.
- If there are no defects, then replaces it with a new battery.
Sometimes a mobile phone is discharged in a short time or does not charge at all precisely because of the oxidation of the contacts. In most cases, this complexity is solved in a few minutes.
