How to find out the battery capacity of the phone - step by step instructions, features and feedback

Few people today imagine a life without a smartphone. Someone uses mobile communication only when necessary, while others do not release the phone from their hands. With such a load, sooner or later an inevitable process occurs - the battery becomes obsolete and requires replacement.

Specialists have found that after five hundred charge-discharge cycles, the battery capacity decreases exactly one-half of the nominal value. This process is not affected in any way by the brand of the phone, nor its value. This article will tell you how to find out the battery capacity. The methods of its preservation and measurement will also be considered in the review.

What is the battery capacity?

The capacity (volume) of the battery, which is indicated among other technical characteristics, shows how long the battery can provide uninterrupted power. The capacity of powerful batteries is expressed in ampere-hours, and small - in milliampere-hours. This value is calculated by multiplying the discharge time by the amount of direct current.

In modern devices, manufacturers mainly install lithium-ion or lithium-polymer batteries. Battery operation is provided by various chemical processes. In the process of operation there are changes in the electrolytic composition, volume, state of the electrodes, which indicates a limited battery life.

So, how do you find out the battery capacity in order to trace the moment of forced replacement in a timely manner? After all, no one wants the phone to "run out" at the most inopportune moment.

How to conduct a visual inspection of the battery?

It is possible that if you have problems with holding the charge, you do not need to find the answer to the question on how to find out the battery capacity of your phone. In some cases, the battery needs immediate disposal. Check the need to replace the part can be an elementary visual inspection.

The critical condition of the battery will be noticeable immediately. As a rule, with prolonged use on the battery, blistering and traces of corrosion, having a green or white hue, are detected. Deformation in the form of bubbles can be seen not immediately, such a defect has the property to increase gradually. However, when bubbles appear, you must immediately replace the battery. Otherwise, the electrolyte simply can damage the microcircuit. A new battery will cost much less than an unanticipated replacement smartphone.

What should alert?

A quick discharge of a smartphone is sure to attract the attention of the owner, because most often only on personal experience when faced with a problem, people are beginning to wonder how to find out the battery capacity. Prerequisites for this action are:

• Reducing the amount of time the phone works at the same load;
• A sudden cut-off and zero amount of energy after reaching a certain percentage of the charge (usually 20%).

However, today it is easy to overlook the moment of the need to replace the smartphone battery due to the prevalence of powerbank devices - a portable battery, with which you can recharge the battery in any place and at any time.

How to check the battery mechanically?

The lifetime of a battery is affected not only by the intensity of use. Factors that reduce the period of battery operation include sudden temperature changes or long idle time. Excessive heat and too much cold are perceived by the device as negatively as the fact that the battery has not been used for a long time.

Swelling of the battery is, as a rule, quite slow and not always immediately noticeable to the owner of the smartphone. To check if there is a chance that the battery will soon be out of order, it is necessary to twist the battery on a flat surface. If there is a bend, the rotation will happen easily.

How can I check the battery capacity by software?

Much more informative than a visual or mechanical way to check the battery can be software methods. So, special commands or applications will help to determine the problem quickly and effectively. The methods vary depending on the operating system of the smartphone.

For iPhone owners who often complain about a lack of charge, experts recommend installing the iBackupBot utility, which is available in two versions - for PC and Mac. However, it's rather difficult to get the necessary data with the utility, so it's better to install the finished application on the computer and then connect the smartphone to it. Running iBackupBot, you need to add the connected device to the list of allowed devices. Clicking on "More information", you can see the necessary data on the screen: the number of charge-discharge cycles and the capacity of the battery. In the event that the specified value is less than fifty percent of the nominal, it is worth buying a new battery.

For those who are looking for how to find out the capacity of the Android battery, there are several methods. So, you can just type on the keyboard * # * # 4636 # * # * and select the "Battery Information" command. After that, the necessary data appears on the display. Checking the battery status with software code does not always work, in which case it's worth installing an application like iBackupBot, from GooglePlay. For phones with the Android operating system, a good program is, for example, Battery. In addition to information about the current capacity of the battery, the application will show the voltage and temperature of the battery.

How can I accurately measure the battery capacity?

Of all the methods that tell how to find out the actual capacity of a battery, the most effective is to measure this value with the help of advanced chargers. Measurements can be carried out by two methods:

1. Charging the phone. It is necessary to choose the type of battery (which is indicated on the battery) and the mode. Calculating the amount of current and time spent on full charge, the device will give the result - the current capacity.
2. Discharging the phone. These measurements can also be carried out in the reverse order. The device will also measure the required quantities (only spent on the discharge) and output the result.

How to measure battery capacity with a tester?

How to learn the capacity of a battery with a multimeter and what is this device? A tester, or multimeter, allows you to determine the place of a break in the electrical network, voltage and resistance, and the operability of the devices. In this case, the use of a tester for determining the capacity of a smartphone battery is not the most effective method, since the values will be only approximate. For more accurate information, it is better to use the above methods: programs or a special charger.

How to measure the capacity of a laptop battery?

How can I find out the capacity of a laptop battery if it is quickly discharged while the battery is running? In the case of portable computers, the situation is somewhat different - you will not need to use third-party programs.

To find out the actual capacity of the laptop battery, you can use standard Windows tools. To start, you need to run the command line and type "powercfg -energy" in it. Additional information will appear on the screen, in which the path will be registered: C: \ Users \ Username \ energy-report.html. Following it, you can finally see the file energy-report.html, when you open it, you will see all the information about the battery: code, manufacturer, number, electrolyte, life, nominal capacity and full charge. The latter values are the actual capacitance values.

So, the question of how to find out the capacity of the battery, in fact, does not cause difficulties. Timely diagnosis and replacement of the battery will extend the life of your smartphone or laptop. In addition, you should regularly clean the connectors of technology from contamination, install specialized applications, do not allow full charging and long battery downtime, if possible, disable unused functions and services.
