The most common failure of a smartphone is broken screen. But if you don’t drop the phone, the battery will most likely fail first. The smartphone will begin to run out quickly, because the battery wears out, and over time its maximum capacity decreases. How do you know how long your faithful friend's power supply has left to live?

Modern Li-ion batteries, contrary to popular myths on the Internet, should not be completely discharged regularly. Unlike older NiCd batteries, they do not suffer from a “memory effect” that reduces the actual capacity. The only problem that regular partial charging can cause is that the phone will begin to incorrectly estimate the remaining battery life. This can be treated by discharging the phone once until automatic shutdown and then charging the phone while turned off to 100%. You should not leave a dead phone for a long time - for a Li-ion battery, remaining in a completely discharged state for a long time can lead to a partial loss of capacity or even damage to the battery.

Most manufacturers describe the battery life in cycles of complete discharge (up to 0%). For modern batteries, this value can be about 500-1000 cycles. If you put the phone on charge at about 10-20%, this will not be a complete discharge - and will allow you to approximately triple the number of cycles.

You can find out your battery model and theoretical number of cycles in the documentation for your phone or on the Internet.

How can you find out how much has already been spent?

Both Android and iOS store a log of battery information in the system in encrypted form and do not voluntarily agree to show it to the user. This information can be obtained using third-party utilities.

In addition to the number of charge-discharge cycles, all of the above programs are also able to show operating temperature batteries. It makes sense to pay attention to this parameter, because if the battery gets very hot, there is a malfunction.

If your phone is one of those that disassembles and you notice that the battery is swollen, replace it immediately. A change in shape is a clear sign that the battery has deteriorated and is already preparing to ruin the rest of the phone by spilling electrolyte into it. Another sign of approaching disasters, which also works for non-detachable devices, is the instantaneous discharge of the phone from 100% to 97%-98%.

Do not overheat or overcool your smartphone, try to charge it on time - and the battery will last you a long time!

Absolutely all people use their Android phones to make calls, communicate in social networks, checks Email, play games and much more. All this consumes battery power.

Therefore, if your smartphone battery is not performing as expected, it can cause serious inconvenience. Luckily, there are many ways to monitor your Android battery level. In this article we will look at how to check the level of wear of a smartphone battery.

Large number of applications

The first step in diagnosing phone battery problems is to take a look at the number of apps you have. In most cases there is not enough time battery life- this is simply a consequence of launching too large quantity intensive (active) applications at the same time. Let's give an example: just as a person gets tired of performing many actions at once, the battery of a smartphone loses its charge more actively if there are many programs running on the phone at the same time.

In order to decide this problem, you can use the Battery Doctor app, which allows you to disable unwanted multitasking, such as apps running in the background.

How to find out battery capacity on Android

Another way to check your Android phone's battery health is with the built-in " hidden menu" Dial the following number “*#*#4636#*#*” in order to open the “hidden test Android menu", designed to eliminate the main problems associated with the operation of the smartphone. When you click on the "battery information" option, it displays detailed information about your battery, including charge status, power source, charge level, voltage and current temperature.

How to Perform Performance Testing

Test Android battery smartphone can also be performed without using built-in diagnostics. Many phones are already equipped with a built-in battery analyzer (each version of Android has its own accompanying program), which monitors which applications are using the most battery. With this app, you can see basic information about your device's energy consumption and then decide whether to remove apps that are using up too much of your battery.

However, such standard tool not as effective as third party applications. You can search for your own battery analyzer as follows: Settings - Device - Battery (or Battery). Below we will briefly look at some of the most popular applications, which will allow you to monitor the health of the battery and personally monitor charge savings.

One of the most popular tools for diagnosing and managing the battery on a mobile phone is the GSam Battery Monitor. Application includes great amount settings and makes it possible to check the actual battery capacity of the smartphone. But the main functions of the application are as follows: monitoring the power consumption usage of other applications since the phone was turned on, power consumption since the last full charge and energy consumption since last shutdown screen. The GSam monitor will also tell you which features and apps drain the most battery power on your smartphone.

Clean Master - best tool for working with smartphone batteries of any size. This app is unique in its ability to provide users with notifications about various aspects phone battery life. For example, if an app is consuming too much CPU power, significantly reducing your battery life, you'll be notified. This information lets you know which app drains your battery more than others.

Using these applications can give you a complete and clear picture of what is draining your battery, while also providing relevant tips on what can be done in this or that case.

note

Each battery lithium ion battery for a smartphone (regardless of the model, make and brand) is designed for certain number charging cycles. That is, the more often you charge the battery, the faster it will fail. Try to make the most of all the battery energy, bringing the charge level to 15-20%, and only then connect your smartphone to the charger.

How to check if your phone battery is working properly?

A smartphone without a battery is like a time machine without a nuclear generator. Unfortunately, even if you take care of your smartphone's battery, it will inevitably deteriorate over time and lose some of its capacity.

At this point, it is quite difficult to determine whether the battery is in good condition or needs urgent replacement. Here are some tips to help you determine the condition of your battery and whether it needs to be replaced.

Visual inspection

You don't have to be a mobile phone designer to tell the difference. faulty battery from healthy. In general, some basic battery faults are easy to notice with the naked eye. If your phone's battery is removable, simply remove it carefully (after turning off the phone, of course) and look for symptoms such as bulging, corrosion near the metal terminals, and green or white spots on the surface of the battery. These are all signs that the battery can be thrown in the trash. If you don't see such external factors, just go to next advice on diagnostics.

However, if you find any suspicious spots or if your battery is swollen, it is recommended that you contact service center, since the battery 100% needs to be replaced, and a specialist must inspect the tube itself to prevent oxidation already at the battery connection terminals.

It is important to know

If the battery is swollen (swollen) and no longer fits into its original place, do not force it into place using brute force. First, a damaged element may leak harmful chemicals. Secondly, you can damage the internal filling of the smartphone, from motherboard to the back of the screen.

Do a spin test

You've probably already seen a spinner and have a good idea of ​​how it spins. Now we’ll tell you how this knowledge will help you check the battery on Android and Apple.

Lithium-based batteries degrade (spontaneously break down) with each new discharge cycle. We have already mentioned this above. Various external factors also aggravate the situation with charge quality - extreme heat or cold can seriously reduce the life of any battery.

But there is another way to completely destroy new battery- This is to remove the battery and leave it lying without any load for a long time. Eventually, the battery may begin to swell. This swelling happens very slowly and can last for weeks or even months, so a hump that has just started to form on one side of the battery can be quite difficult to notice.

Let's learn how to determine the number of battery charging cycles Android phone or tablet, as well as determine the degree of physical wear and tear of the battery.

This article serves as a continuation of the previous ones: and.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Features of modern batteries

Contrary to popular myths on the Internet, modern Li-ion batteries do not need to be completely discharged all the time. They do not suffer from the "memory effect" that reduces the actual capacity, unlike older NiCd batteries.

The only problem that regular partial charging of Li-ion can cause is when the gadget incorrectly estimates the remaining operating time. The problem can be solved by discharging the device to 100% once while it is turned off. There is no need to leave the device dead for a long time - for a Li-ion battery, finding long time in a completely discharged state leads to battery damage or partial loss of capacity.

Most manufacturers describe the battery life in cycles of complete discharge to 0%. This indicator for modern batteries is approximately 500 - 1000 cycles. If the gadget is charged at a value of 10 - 20%, then this will not mean complete discharge, and the cycle time will approximately triple.

Visual inspection of the battery

You don’t need to be a specialist to distinguish a damaged battery from a “healthy” one. Most problems can be seen with the naked eye. If your tablet or smartphone has a removable battery, you should remove it after turning off the device. After this, the following symptoms should be checked: swelling, white or greenish spots, corrosion around metal contacts.

If this is observed, then soon the gadget may become completely unusable. If you notice a distortion in the shape of the battery or suspicious spots, you must immediately purchase a new battery. A problematic battery should not be put back in order to prevent electrolyte from spilling inside the device and damaging it.

"Rotation Test"

Lithium-based batteries degrade with each cycle. Improper storage only aggravates the situation - for example, hypothermia or overheating significantly reduces the battery life. If one in a great way To break the battery, it will discharge to zero and remain in this state for a long time.

The battery may gradually swell, a process that occurs over weeks or months. You won't notice the slight bend right away. A simple test can check this: the battery to be removed should be placed on a flat surface and twisted. If it rotates easily, then this is not a good sign.

Not all batteries can be easily and quickly removed and examined. In this situation, it is necessary to pay close attention to the speed of battery discharge. You should be alarmed by a loss of two or more percent at once and a rapid discharge to 0 in a couple of hours. These signs indicate that the battery will soon become unusable.

Software methods for checking the battery on Android

Android contains a log of battery information in an encrypted form in the system. This information can be obtained using special utilities. For example, the Battery application, “Battery Care” and other analogues.

Increase

You can find various magic codes on the Internet, but they do not work in new versions of Android. In addition to the number of charge and discharge cycles, these utilities demonstrate the operating temperature of the battery. On this parameter It is worth paying attention if the battery gets very hot.

AccuBattery for Android

The AccuBattery application reads information from the battery controller and displays it in a visual shell. The utility helps you choose the most optimal charge, determine the applications that consume the most power from your gadget, and find out about the current battery wear.

Development of AccuBattery began after Dutch engineers tried to extend battery life. Not here we're talking about about slowing down discharge during the day. The goal is to ensure that the battery does not lose capacity after many months of use. The problem is also relevant because there are many modern gadgets come with non-removable batteries.

The developers conducted a series of tests, as a result of which important conclusions were drawn. There is no need to charge the device throughout the night, since during reboots the power source loses its capacity. The reason for this is the chemical processes that occur in the battery.

IN mobile devices There is an internal switch that stops charging when it reaches 100%, but power continues to flow, which affects the oxidation resistance of certain chemicals. It turns out that for fully charged The tablet or phone should be disconnected from the power supply as soon as possible, after being fully charged.

Most best option Battery charge is 80%. The AccuBattery app has a built-in alarm that sounds active signals when the optimal charge level is reached. It is located in the “Charging” menu.

"Charging" section

At the top of the working window there is a roundness, in the green part of which the current charge percentage is shown, and in the blue part - the acceptable one. The threshold of 80% is set by default, but it can be lowered or increased. To do this, you need to move the slider and pay attention to how this affects the damage to the battery.

Increase

If you scroll down the window, you can find out the charging speed of your device from various power sources. For example, connect the “native” charger, then turn off the device for a couple of minutes and look at the Charge speed tab. It indicates exact information about the amount of time remaining until the optimal charge. To compare speed, you can repeat the steps with external battery or others charger.

Section "Discharge"

This section displays statistics on battery consumption since the last charge. The following information is available in the Battery usage subsection:

• How much percent was spent when the screen was turned off or on and over what period of time.
• Which apps cost the most? big number ampere hours (mAh).
• How long the gadget is in sleep mode, how often this mode was interrupted.

Increase Increase

You can also consider the list of applications that actively used the battery. The AccuBattery developers claim that their method of change is more accurate than that offered by the Android system.

Sections "History" and "Health"

The Health section is the main advantage of the application. When connected to a power source, it begins to track exactly how much energy is entering the battery and what percentage of the full charge it is. Based on the information received, the residual capacity is determined. To obtain a more accurate determination of the current capacity, several long charging cycles should be performed.

Everyone, even not the most experienced user of mobile devices, has asked this question at least once. The functionality of the devices and their battery life completely depend on the battery charge. If you buy a battery with very high performance, but with a low capacity, you will not be able to fully use its resource, since it will constantly require recharging.

Over time, owners of devices with fairly capacious batteries face the same problem, when a full charge only lasts for a couple of hours of not very active use. This is the first alarm signal after which you need to check the performance of your smartphone battery. This is easy to do even at home. Let's consider the simplest and most accessible methods for this procedure.

The online electronics store site offers a wide range of laptops, phones, TVs and other electronics, as well as gadgets and accessories for them. If you are planning on getting a good price from a warehouse, we recommend that you familiarize yourself with our catalog of TVs from LG, Samsung, Sony, Philips. Many items are available in stock in Odessa.

How to check the status of your smartphone battery

Before using advanced verification methods, you should execute visual inspection batteries. If the capacitive element is built-in, then you need to pay attention to the visible plane. It should be absolutely smooth, without swelling or bulges. The appearance of these defects indicates a malfunction of the battery and the need to replace it. Also, the battery should not overheat, especially when using the smartphone passively.

To check the functionality of your phone's removable battery, you need to place it on a table and try to spin it. If it fits tightly with its plane to the surface of the table and rotates with difficulty, then no problems with him. If the battery instantly spins like a top, then it needs to be changed. In addition, there should be no visible damage to the capacitive element, and the metal contacts should be clean.

For mobile devices based on operating system There are several ways to check battery health:

• by using system utility;
• using special applications;
• using a multimeter.

To activate system program on a smartphone, you need to enter a special multi-digit code in the call menu: *#*#4636#*#* . Then in the window that appears you need to go to the menu "Battery Information", where all the main characteristics of your battery will be indicated, including its current condition.

In order not to remember this complex combination of symbols, you can install one of the many applications from the Play Market:

• AccuBattery
• Battery Life
• Power Battery
• Battery Calibration and many others.

With their help you will receive full information about nominal and current characteristics, as well as about the level of charge and wear of the battery.

More experienced users can check your phone battery capacity using a multimeter. To do this, you need to look at the nominal voltage on the battery itself (it is measured in Volts and is usually 3.7 V), and then charge the device to 100%. Then measure the actual value. If it corresponds to the passport data, then the battery is normal, and if it deviates by more than 20%, then the battery does not work correctly.

If you are looking good internet TV store and planning from a warehouse from a supplier - you have come to the right place. In our catalog you will find more than 450+ models of TVs from around the world. brands in stock in warehouses in Odessa and on order 7-14 days.

Also worth pay attention to how quickly the battery drains. If after 10 minutes of talking at 100% the battery has lost at least 10%, then this means that it does not hold a charge. Such a minor load should not significantly reduce the capacity of the element.

How to find out the wear and tear of your smartphone or iPhone battery

For mobile devices with operating system iOS system You can also check battery performance in several ways:

• using applications from App Store;
• using a multimeter;
• using the iBackupBot program.

One of the most popular applications for - Battery Pro. It allows you to find out in a few seconds the battery capacity, nominal characteristics and the percentage of its actual wear. By installing it on your device, you can effectively monitor battery performance in real time.

A special program has been developed for Windows that allows you to diagnose the battery of an iPhone connected to a PC. It should compare two main characteristics of the battery:

• DesignCapacity (nominal capacity value according to the passport data);
• FullChargeCapacity (actual capacity value at the time of diagnostics).

Also check iPhone battery You can practically use a multimeter. This method is absolutely identical, as in the case of a smartphone on Android based. We have reviewed the most popular and available methods, how you can find out the capacity of your phone battery at home and determine its level of wear.

What are the ways to check the actual battery capacity of your phone?

When using a mobile phone, the battery gradually degrades with each charge-discharge cycle. This process is inevitable and, one might say, natural. Moreover, it does not depend on the phone model, its price and functionality. In modern mobile phones lithium-ion (Li-Ion) and lithium-polymer (Li-Pol) batteries are used. Lithium batteries lose up to 50% of their nominal capacity in 500 charge-discharge cycles. We can say that this is the norm. In 2-3 years permanent job they are exhausting their resource. I would like to know how much longer the battery will last and when to prepare to replace it. To do this, you need to be able to determine the battery capacity of your phone. This is what we will talk about today. But first, a little about the concept of capacity itself.

Battery capacity is the ability to store and return energy direct current. The unit of capacity is ampere-hours or watt-hours. Simply put, the capacity of a phone's battery shows how long the battery can provide power to it. For example, 750 mAh means that the battery can supply 1 mA of current for 750 hours.

The battery capacity is calculated as the product of the discharge time and the amount of direct current.

Many different chemical processes occur in a phone battery, resulting in degradation. For example, the volume and composition of the electrolyte, the condition of the electrode material, etc. change. As a result, the capacity decreases, and gradually we come to the conclusion that it is time to replace the battery.

How to know that the battery will soon exhaust its life. Now we will talk about some ways to determine the wear of the battery, and then about a way to measure the battery capacity.

How to check the status of your phone battery?

First you should conduct a visual inspection. If your phone's lithium battery has serious problems, it will show naked eye. Most often after prolonged use lithium batteries swell, noticeable traces of corrosion appear on the contacts, white and greenish marks appear.

You should also be too wary fast discharge phone battery. That is, if previously the battery lasted three days, but now it lasts for one day with the same intensity of use, this is a reason to take a closer look at the condition of the phone’s battery.

In addition, when the battery life is exhausted, its charge on the phone may drop sharply. For example, it shows 25%, and then suddenly after one short call it shows zero charge and turns off.
To keep your phone from switching off inopportune moment, you need . You can read about it at the given link.

Applications for getting battery information

How can I get information about battery phone without taking it apart. For this there are special programs and OS commands. Let's look at them.

iOS

For owners iPhone smartphones We can recommend using the iBackupBot utility. It is quite difficult to dig out information from the operating system here and it is better to use ready-made application. In order to use iBackupBot, you need to install the utility on your computer, connect your iPhone to it and run the program.

Next, you need to select your device from those offered and click More information. The program will provide you with information about the number of completed charge-discharge cycles and the capacity value. If the value is significantly less than the nominal value (less than 50%), then the battery must be replaced. iBackupBot comes in PC and Mac versions.

Android

Digital request

To get information about the status of your phone’s battery directly from the Android OS, you need to send a request *#*#4636#*#* and click “Battery information”. After this, information about the battery will be displayed on the display. Below is an example for Samsung Galaxy Nexus.
