Calibrate iPhone Battery
We are going to teach you how to calibrate a battery. One of our iOS tutorials to get the most out of your Apple devices.
Perhaps it has happened to many of you that your battery has run out much earlier than normal. It can also happen that with 11% battery life your iPhone has turned off. You can rest easy. Normally it is a problem derived from the calibration, so we must calibrate the battery.
If after the battery calibration the battery still runs out as before, you may need to change it.
This is because we have charged our iPhone or iPad in a bad way. What does this mean? Well, we have not finished charging, or we have charged without reaching less than 20% and even, something very normal, we have charged our iPhone with the iPad charger (we must bear in mind that the power adapter is more powerful and may decalibrate the battery).
How to calibrate the iPhone and iPad battery:
Steps to follow:
- The first thing we have to do is drain our battery to the maximum. When we say full, we mean that we have to drain the battery until our device turns off.
- Once it has been downloaded, we will have to wait a minimum of 2 hours (3-4 hours are recommended, but we have tested it with 2 hours and it works the same). We will have to carry out this process because lithium batteries, once our device has been turned off, still have a little charge left.Hence, they have to be left for a few more hours.
- Once that time has passed, we connect our iPhone, iPad or iPod Touch to the current. We let it charge for 6-8 hours. This means that even if it tells us that it is at 100%, we will have to leave it for a minimum of 2 hours. more, to complete the calibration.
- After this, we do a Hard Reset to restart the iPhone, before disconnecting it from the power.
Doing as mentioned, we already have our battery calibrated and ready to work, almost like the first day.
How to know if the iOS device battery is correctly calibrated:
To know if the process of calibrating the battery of the iPhone and iPad has gone correctly, we will have to look at the time that It takes our battery to go from 100% to 99%. When properly calibrated it takes a long time to jump from 100% to 99%. After doing the test, it took us almost 1 hour.to pass to 99%, making normal use. If we leave it idle, it may take much longer.
We can observe the same thing when our device is about to download and we are at 1%, in this case we notice that it takes a long time to download completely. It took us almost as long to turn off completely as it did to go from 100% to 99%.
Therefore, if your battery is giving you some kind of problem, try calibrating the battery and you will surely notice the difference.
You can also set your iOS device to consume the least battery power.
