There are dozens of cool techniques that are able to save the battery of a smartphone-we at TecMundo have already taught a huge variety of methods to enhance the power usage of Android devices . We’ve even explained how you can figure out when you need to swap the component and know if it’s”healthy.”
However, we never talked about calibrating the battery of mobile devices here, and for the first time there is everything. Yes, on mobile phones and tablets with Google’s operating system , the battery becomes slightly malfunctioning after some time of use, and this is basically the fault of Battery Stats, an internal system process responsible for managing this component.
The records in this process end up corrupting over time and displaying data that is not real, which causes the device to shut down before the battery level reaches 0% or the power consumption seems to increase without explanation. Through this tutorial, we will teach you how to calibrate Battery Stats on devices with or without root access.
1st method: no root and no applications
With the appliance on, charge it until the battery is 100% full. Then unplug the charger and turn off the device. Reconnect your smartphone or tablet to a power source and hold it there until the battery is fully charged again(you need to use another method of knowing when this happens, such as keeping an eye on some LED light).
Now unplug the charger, turn on the gadget, enter your settings window and turn off the screen automatically(allowing the display of the product to be uninterrupted). Again, plug in the charger and wait for the battery to be at 100% capacity. Unplug it and keep your phone turned on and off until your battery has run out and it”dies automatically”.
Calm down, we’re getting there! You only need to recharge it up to 100% and turn it on normally. Now, the Battery Stats should be working properly and you can now set it up again so that the screen turns off automatically.
2nd method: without root and with the Current Widget
This other method for appliances without root is a bit simpler, but requires you to install an application to assist it. This is the Current Widget: Battery Monitor , which is free and compatible with version 1.6 Donut or higher of Android. After installing it on your device, activate the widget in question and find-through other apps or official information from your device manufacturer-what the total battery capacity of the gadget is.
With this information in hand, connect the smartphone or tablet in question to the charger. If the Battery Stats process is corrupted, the device’s power indicator may even show that the battery is at 100% capacity, but the Current Widget will indicate that the amount of mAh has not reached its full capacity. Keep the device plugged in until the widget indicates the same total milliamps you previously discovered.
When this happens, unplug the appliance and restart the system. The Battery Stats should understand that that amount of mAh corresponds to the 100% charged battery and will work properly again. You can now uninstall Current Widget.
3rd method: with root and with the Battery Calibration
If your mobile device has root access, there is a simpler way to calibrate its battery. First of all, go to Google Play and download Battery Calibration for free . Then charge the device until its indicator shows that the battery is at 100% capacity. Open the newly installed application and look at the”mV” number it has; Follow it until you are sure that number will not go up any more.
When the amount of mV is complete and the indicator shows 100% battery power, tap the”Battery Calibration” button so that the program calibrates the Battery Stats automatically. You can now unplug the device from the wall outlet and even uninstall the used software if necessary. Another option is to keep it installed in the gadget if you need to call the next method.
4th method: with root and using Recovery Mode
If nothing else works, try this last technique. Turn off your device and turn it on in Recovery Mode. Each model has its own way of entering this mode, but usually involves keeping all physical buttons pressed during the boot process. Inside Recovery, enter the”Advanced” section and select the”wipe battery stats” option. This will erase all calibrations made by the system or by the user.
Now drain the device’s battery all the way down(causing it to”die” completely) and allow it to recharge up to 100% of its capacity. Important: Do not use your phone or tablet during this process! When charging is complete, open the Battery Calibration and tap the center button on your interface again to calibrate it. Now, your battery should be working perfectly and with no vices.
