How to calibrate your Android phone battery step by step


Battery on Android

Over the years there has been a long talk about the smartphone batteries, but there are still doubts today about which are the best ways to upload and download, what causes its degradation or not, and which of the most common recommendations really help save energy or which are myths. Fortunately, little by little, we are getting more and more clear information about the power source that gives life to our terminals, and some insist on taking care more than the device itself.

One of the most common procedures, probably more than one of you has heard at some point, is the battery calibration. But is this process really necessary? And if so, What are the steps to calibrate your phone's battery? In this guide, we intend to put an end to all doubts on the subject, and thus eliminate the myths that exist about whether battery calibration is necessary, or whether it can be counterproductive and harmful.

What is the use of calibrating the battery and how often do you need to do this?

Components of a mobile phone

Virtually all mobile phones launched in the last two decades incorporate lithium ion batteries. However, it was in the year 1990, when this technology was fully developed, although it underwent different changes and evolutions over the years, and started to be used in devices directed to the commercial field.

In the case of smartphones, although they are batteries based on the same technology, experts in the field The Battery University consider that these devices integrate "Smart batteries", that somehow they are able to communicate with the device itself and finally with the user through it.

The problem is that when designing energy sources, engineers mistakenly assume that the batteries will remain in good working order throughout their entire life. This, unfortunately, it's not like thisand, in fact, the degradation of batteries is a process that is impossible to avoid and, in most cases, irreversible.

Degradation and the passage of time affect not only the battery's own autonomy but can also affect the accuracy with which the remaining level is measured. This causes a very common problem in modern smartphones, which is that the operating system indicates a wrong battery level remaining, which can end up being translated into other more serious problems like what the cell phone extinguishes when there is still 20% battery.

What really happens in this last case is that the actual battery level does not match the indicated by the operating system, since the passage of time has accentuated the margin of error to the point that the software does not obtain accurate measurement by the battery. This is partly the fault of the user since, in general, "smart batteries" are calibrated autonomously through full and timely loading and unloading cycles, but many users rarely do this – probably because of the many claims battery is said to completely discharge the battery may damage it. It is precisely in these cases, when the you must calibrate the batteries manually.

Yet, What happens if the calibration is not performed periodically? Although battery operation itself should not be affected – at least not directly – nor is it something that damages the integrity of the cells, experts say that a badly calibrated battery means that the readings made by the operating system will be less accurate and therefore less reliable.

With this in mind, the next question that comes to mind is how often should we calibrate the cell phone battery. Resorting to The Battery University, a frequency of a calibration process every 3 months of use or every 40 partial charge cycles May be a good recommendation.

How to calibrate your Android phone battery


Now yes, it's time to calibrate the cell phone battery. While there are apps on Google Play that are designed to run this process automatically, actually performing the calibration is a lot easier than it sounds, and does not need external help or specific tools. To calibrate the battery of a mobile phone, be it Android or based on any other platform, you only need Please follow these steps:

  1. Empty the battery of your smartphone until the "Low battery" warning appears – according to The Battery University, it is not necessary to exhaust the battery until the phone turns off.

  2. Recharge the battery completely.

That is all. Nothing to leave the phone off and no battery for several hours, or plugged into the charger once it reaches 100% for many others, or any other myth related to the battery calibration process that has flooded the network for years. By performing these two simple steps once every several months, we must end the main consequence of a decalibrated battery, which is nothing more than erroneous readings of the energy level remaining by the operating system.

If what you were looking for is to extend the range of the phone to the maximum, as if it were new again, I fear that What you need is to fight against natural degradation. And faced with this problem, there is no such a simple solution.

And while degradation is an impossible process to avoid, there are recommendations that can serve to take care of the cell phone battery and delay this process. Some of the most recommended procedures, which we must all carry out, are the following:

  • Avoid extreme temperatures: above all the heat. Lithium-ion batteries are sensitive to both temperature and sudden changes in temperature. It is best to keep the battery – and therefore the cell phone – at a temperature around 15 degrees whenever possible.

  • Do not download full: As I said before, lowering the battery completely can adversely affect its performance. In general, it is best to always keep the battery level between 30 and 80%.

  • Do not worry about the first charge: As soon as you get your cell phone and get it out of the box, enjoy. When it is time to charge it, plug it in without worrying about whether it is best to fully drain the battery or leave it charging for several hours. This is a myth inherited from nickel batteries, which required some care during its first charge.

  • Always use the original charger: and when it is not possible, at least use a compatible and certified, and under no circumstances use a charger of an unreliable brand.

  • If you will not be using the phone for a while: In this case, it is best to keep the battery level at around 40%. It is not recommended to fully charge the battery before leaving the device without using it for long periods of time.

  • Charge your cell phone at night, yes or no? leaving aside the fact that it is better to perform partial, not complete, loads, the truth is that leaving the phone plugged in at night is not dangerous. Intelligent lithium-ion batteries disable the charge flow after it is complete.
