How to diagnose the health of your smartphone's battery

Undoubtedly, smartphones evolve more and more each day and new functionalities or capabilities that can be developed through these smartphones come thanks to its powerful hardware and its varied software. But it is clear that the source of energy or the one that gives all smartphones the power to use them is the battery.


Unfortunately, even if you are careful, the battery inevitably deteriorates with the passage of time and loses part of its load capacity. But it is difficult to know when a battery is still in good condition or if on the contrary it already begins to need a replacement.

That is why they will show some tips to assess the health status of the smartphone's battery to detect the time that needs to be changed and thus avoid possible damage to the terminal.

Visual inspection

In many occasions, there are many users who after purchasing a smartphone, it is replaced by another without ever having removed the lid where the battery is. This is a sign that a visual check of the battery's condition has never been made.

It is recommended to check from time to time if the battery shows signs of deterioration and for this, you must proceed by turning off the terminal and carefully removing the part of the housing that covers the battery. Once the phone is discovered, the battery should be removed and observed if it shows symptoms such as bulging or signs of corrosion near the metal terminals where the battery itself connects with the device.

These can be easily detected as they leave white or green spots and are the ones that can damage the phone's circuits. If so, you must proceed to change the battery and not put back the one that has caused these damages.

Turn test

Lithium batteries are degraded with each cycle of discharge, but exposure to extreme temperatures of both cold and heat can further shorten the life of the batteries. One of the symptoms of the bad health of the battery is the swelling of it by some part of its surface.

This swelling occurs in a slow process that can be quite difficult to appreciate especially in its beginnings, but an easy way to check it is by trying to rotate the battery on a flat surface. In the event that the battery has no swollen area the battery will not turn easily, while if a part of the surface is inflated, the battery will easily rotate on a flat surface using the swelling itself.

Observe if the battery consumption is fast

Not all phones can be removed easily and can, therefore, be inspected by users. In these cases, it is convenient to have control of the speed with which the famous lines of the battery are decreasing.

In most phones, you can see the battery percentage that is available at any time as a percentage in the status bar. In addition, this information can be found as an option within the configuration menu. If not, you can always use a widget that shows this information to detect if even with infrequent use of the terminal the battery is quickly consumed and if so, it should be changed.

Diagnostic applications

iPhone users will know that the terminal itself keeps track of the times it is charged and the actual capacity of its battery. However, this information is accessible only by Apple support personnel.

To access this information you must get iBackupBot and connect the iPhone to the PC. From then on you can access the count of the load cycles and the actual capacity of the battery at any time to check your health.

In the Android terminals, this data is also stored on the status of your battery. In some terminals, just press the following sequence from your dialer * # * # 4636 # * # * and they can be visible. But at other times it is not so and therefore you have to choose to get software that provides it to us.

An example is MicroPich, a simple battery monitoring tool that will show the health status of the battery, its voltage, its temperature and the exact battery level consumed at each moment.
