Often times, smartphone manufacturers recommend calibrating your Android device's battery on a regular basis. But what exactly does that mean? And is battery calibration really necessary? We'll explain it to you.
What exactly is a battery calibration?
To understand battery calibration, you need to understand some basics about how batteries work. Each 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 in 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 has to "learn" the capacity of the battery. When the battery is completely discharged to 0 percent and then fully charged to 100%, the chip learns the capacity.
If you use your phone frequently, the battery will discharge and charge repeatedly. This multitude of charges causes the chip to miss its accurate reading. In short, at this point the chip and chemical capacitance are not calibrated. To get an accurate idea of the battery's capacity, you need to calibrate it. The battery calibration is all about an accurate display of the battery indicator. This does not improve the service life. This is a pre-lithium-ion battery myth. The condition of the battery is not improved either. High wear and tear will affect calibration, but battery health will only depend on usage. Here we explain how you can save the battery of your Android smartphone..
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 then 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 your battery
First of all, discharge the battery of your smartphone completely. So don't charge it at any point and wait for it to shut down. If it has switched itself off, restart it so that it switches itself off again. Although the battery is at 0 percent, there are still some reserves..
Now charge the phone to 100% while it is switched off. You can use a quick charger for this, but make sure it hits 100%. As soon as the battery is fully charged, unplug the power cord and start the phone. This cycle of fully discharging and charging allows the chip to calibrate its readings with the battery's charging cycle.
