Smartphone manufacturers often recommend regularly calibrating the battery of your Android device. But what exactly does that mean? And is battery calibration really necessary? We will explain it to you.
What Exactly Is A Battery Calibration?
To understand battery calibration, you need to understand some of the basics of how batteries work. Every battery has a smart chip. This chip sends a signal that indicates the current state of charge of the battery. Your Android smartphone receives this signal and displays it on your screen. The chemical element of the battery (lithium or nickel) is what stores the energy. The chip tries to read how much of this energy the battery has stored. For the most accurate measurement possible, the chip must "learn" the capacity of the battery. If the battery is fully discharged to 0 percent and then fully charged to 100 percent, the chip learns the capacity.
If you use your phone frequently, the battery will be discharged and charged several times. This large number of charging processes means that the chip misses its exact reading. In short, the chip and chemical capacity are not calibrated at this point. To get an accurate idea of the capacity of the battery, you need to calibrate it. Battery calibration is therefore only about an accurate display of the battery indicator. This does not improve the lifespan. This is a myth from before lithium-ion batteries. The condition of the battery is also not improved. High wear and tear affects calibration, but battery health only depends on use. Here we have already explained how you can save the battery of your Android smartphone and how to properly charge your mobile phone.
You only need to calibrate your battery if you get inaccurate readings. For example, if your smartphone shows a battery level of 30%, suddenly drops to 5% and switches off immediately afterwards, this indicates an uncalibrated battery. Nevertheless, you should only calibrate the battery if you have not used the device for a long time. Because a deep discharge of the battery can affect the service life. The more often your battery discharges completely, the shorter its lifespan.
How To Calibrate The Battery On Android Smartphones or Tablet
First drain the battery of your smartphone completely. So never charge it and wait for it to turn off. If it has switched off, restart it so that it switches off again. Although the battery is at 0 percent, there are still some reserves.
Now charge the phone 100% as long as it is switched off. You can use a quick charger for this, but make sure you reach 100%. As soon as the battery is fully charged, pull out the mains plug and start the cell phone. Through this cycle of complete emptying and charging, the chip can calibrate its measured values with the charging cycle of the battery.
