CALIBRATE iPhone Battery  ▷ Step by Step Guide ▷ 2020

Batteries are still today one of the main problems of mobile devices, specially for The iPhones. And is that despite all the technological advances that exist, the load on mobile phones is still very short. In general, these charges usually last 1 day or a little longer when the equipment is new, but over time this gets worse, so much so that it usually only lasts a few hours.

However, in recent years mobile batteries have been presenting some improvements in the devices but, their manufacturers are still more concerned because charging time much faster and not in how long it can last. Although currently these charging batteries tend to last longer, they are still insufficient for meet the needs of users.

In such a way, that the same user has to take care of extending its useful life in order to ensure that it can last as long as possible and not discharge so quickly. One of the main signs that they are being damaged is when the equipment begins to turn off even with some charge. For iPhone phone, it is recommended that when the battery reaches 80% of its charge, the charge is slowed down in order to protect the battery and in turn extend its useful life.

What does it mean and what is the use of calibrating the battery?  Advantages and disadvantages

Calibrate the battery of a mobile equipment is one of the best tools that we can use to try to extend its useful life and therefore get better performance. In general, when you buy a terminal, your battery usually comes already calibrated but, with the passage of time and the different charges that are being made, all this causes that the calibration is lost.

When we refer to a calibrated battery we refer to the time it takes to pass 100% to 99% or 1% time to shutdown. In such a way, when this is lost, it can become unbalanced by up to a 5% or much more, This means that the mobile can turn off even with 5% or 10% load and go down in just minutes or seconds from 100% to 95 or 90%.

This ends up causing problems that in the long run will breaking down the battery life, all of this becoming a problem for users. But, as every process has both its advantages and disadvantages, which we are going to show you below:


Among the main advantages offered by this process we can find the following:

  • It will help you offer the actual percentage of your battery.
  • It will increase the life of the battery.
  • It will improve the Smartphone performance.
  • You will avoid sudden blackouts.


As we have already said before, every process has its pros and cons and as you can see this is not the case. That is why here we give you some reasons why You should not calibrate your iPhone cell battery.

  • When achieving good results, it will cause this to be carried out constantly which can cause battery damage.
  • It will only fix the battery for a short time, especially when the battery is old.
  • It is not a miracle method.
  • If you perform the calibration procedure incorrectly, you can cause damage such as battery swelling, very slow charging, battery overheating.
  • Stagnation in a low load percentage.

If you are having problems with charging your iPhone This may be due to the fact that it has been miscalibrated. If this is the case, your team will most likely turns off unexpectedly, low battery percentage very quickly, or when it is at 5% or 10% it turns off. If you present some of these errors you can perform this procedure to try restore battery performance and make the battery last much longer

To be able to calibrate the battery of your iPhone you just have to follow these steps:

  • The first thing to do is to charge the Smartphone until it appears on the screen that the charge has reached 100%.

  • When this percentage has been reached we disconnect it from the charger and use it as every day until its battery is depleted. It does not matter if the mobile is used more than the other days or the same, the objective is to make computer shuts down by itself when unloaded.
  • When the terminal is off, we must leave it without charging about 6 to 8 hours.
  • Once this period of time has passed, we connect the mobile to the charger again and leave it plugged in between 6 to 8 hours. During all this time it is recommended not to use the mobile phone, as well as to place it in airplane mode.

  • When the charging time has elapsed, the next thing to do is disconnect it from the charger and reboot the device, for them the sleep and start button for a few seconds for this to take place. After a few seconds the apple logo and the whole process will be finished, you just have to wait for the phone to turn on and you can start using it normally.

What are the reasons why a battery goes out of calibration? Tips to make it last longer

It is almost impossible to prevent a mobile phone battery from going out of calibrationLike all electronic accessories, it suffers wear and tear that causes its performance to deteriorate. In the case of batteries, their charge percentage is measured based on algorithms that are inside the mobile operating system and their operation is related to different factors.

Some of the reasons why mobile devices are decalibrated is due to having the equipment longer than it should be connected to the charger, that is to say, this reaches 100% and continues plugged what can cause raise the temperature more than indicated. If this happens you are basically causing a degradation in battery thus causing it to be decalibrated.

Another factor that can affect the performance of the stack is fast charges, these increase significantly Degradation. Therefore, use wireless charging is not recommended, always try to use normal charges even if it takes a little longer.

Avoid placing the Smartphone in hot places, with sun or places where it is tight, This could cause the equipment to overheat and cause its temperature to rise greatly which can lead to further degradation in the stack causing its performance to decrease.

These are some of the reasons that can cause the battery of the iPhone or any other mobile device to be out of calibration. Thus, it is recommended to calibrate it from time to time But, you must bear in mind that doing this procedure very often can considerably affect the useful life of your equipment. In new equipment it is recommended to do this after 6 months of use.
