Android Battery: Calibration without Root Rights

For all current smartphones, whether they are devices on iOS or Android, the issue of autonomy is particularly acute. The thing is that phones are now processing large amounts of processes that require a lot of energy.

Relative salvaging of this situation can be the calibration of the battery. Its essence consists in the forced adjustment of the battery, which leads it to the optimal state for use. After all the manipulations, your battery will hold the charge for as long as possible. Next, we'll show you how the new battery (Android) is calibrated.

Calibration Features

Forums on the Internet are just full of all sorts of advice on calibration. In general, there are only a few proven methods, they will help fulfill the task. As mentioned above, the biggest problem for many smartphones running Android OS is the battery. Calibration can occur as follows:

1. On smartphones with Root access (2 methods).
2. Without Root access (also 2 methods).

We'll talk about each of them in detail later. The process of calibration is actual only if the phone is really discharged quickly (in less than 5 hours of average load) or the battery is displayed at a high level (90-95%), and the cellular phone is switched off for nothing. It is in such cases that you should think about calibration.

Calibrating the Android battery without Root: Method 1

The first step is to find out the capacity of the battery (in mAh). You can find this out from several sources: from the Internet, in your device's passport or directly on the battery, where the required number should be written. Then we follow this algorithm:

1. Go to the Play Market, where we are looking for and installing the CurrentWidget: Battery Monitor, which will show the battery charge in milliamperes.
2. Tracking the level of charging, we charge the smartphone as much as possible to the mark that is provided by the manufacturer.
3. When the desired charge is reached, turn off the phone and turn it on again. Rebooting the device is required in order to determine what is the true battery charge level at the present time.
4. For the need to repeat 2-3 times.

After such simple manipulations your smartphone should remember the necessary level of charging, correctly displaying the data on your Android. The battery, which was calibrated more than once, will not be able to show high results of autonomy, so we'll have to think about replacing it.

Some phones have a "default calibration" feature. In order to start it, go to the battery setting point (Menu - Settings - Battery), where we select from the "Calibration" drop-down list. We start, wait for 10-15 minutes and load the device. This completes your actions.

Calibration without Root: method 2

The second method is a kind of variation of the predecessor, it differs only in that there is no need to download programs. The algorithm is as follows:

1. In order to perform calibration, we charge the battery to the maximum, after that we disconnect the charger and the phone itself. Then connect the charging cable to the disabled device and continue charging until the LED indicator turns green, which means that the battery is fully charged.
2. Again, start the smartphone and turn off the ability to go into "Hibernate." As a rule, you can do this in the display settings. To perform this action is to ensure that the smartphone is discharged as quickly as possible.
3. After waiting for the moment when the charge level drops to 1-2%, we connect the charger again, so that Android can properly consume battery resources and observe a full cycle of work. Do not forget to return "Sleep Mode".

All this will improve the performance of your Android. The battery (previously calibrated) will be able to hold the charge longer and will correctly display the data.

Calibration with Root Access: Method 1

If you have Root access (that is, the superuser mode is enabled) to the files, do the following:

1. Install the Battery Calibration application so that the Android battery is properly calibrated. The program will show the exact battery level, not the data that is displayed on the display.
2. Continue to charge the smartphone until the application shows a 100% mark. When the battery has reached full capacity, press "battery calibration".
3. Then we reboot the device and enjoy the tuned device under the OS "Android."

This completes the first method with Root access.

Calibration with Root Access: Method 2

So, we do the following:

1. Go to Recovery mode and go to the "Advanced" section. There we find the menu item Wipe battery stats, which will remove all calibrations made by the user before.
2. Then completely empty the device until it turns off.
3. After that, put the smartphone back on the charge and, not including it, we charge up to 100%.
4. We start the device without disconnecting the power cable, then we perform the calibration in the program Battery Calibration. This step will further enhance the settings, letting the OS understand what is required of it.

In general, the above methods are the main methods of battery calibration.

Battery calibration on an Android tablet

The market for tablets is very diverse today, because a fairly compact device sometimes replaces a stationary PC or laptop, which is very convenient for frequent travel. Of course, most of all devices are running Android OS. As in the case of smartphones, the devices are very low, which is very unfortunate. Calibration of the battery on the tablets is no different from the same in the phones, because the operating principle of the OS itself does not change.

Next, we give an algorithm proposed by Google to the developer of the Android OS. A battery that is calibrated with all instructions will show better autonomy and correct operation.

1. We charge the tablet to the maximum. Even if we are told that the process is over, we continue to charge the gadget. The first item must be no less than 8 hours. Of course, the machine itself must be switched on.
2. Then we take the charger out of the socket and turn off the tablet.
3. Again, start charging the device for an hour, then pull out the power cable and turn on the device. We keep it in this state for a couple of minutes, after which we turn it off again and put it on charge again.
4. After one more hour, we disconnect the charging and turn on the tablet, enjoying the fact that the Android battery was successfully calibrated.

Samsung, Asus, Lenovo and other market giants produce, as a rule, high-quality products, which do not save on details. So there should not be any problems with calibration. If nothing helps, it's worth thinking about buying a new battery. As a tip: do not use USB very often as a charger, as this can seriously damage the tablet or smartphone.

Myths and their refutation

Often we meet people who advise to "swing" or "train" the battery by completely discharging the battery. Once the effect of memory really worked, but it was relevant for nickel-metal hydride batteries, which are not found in the modern market. Now all the devices are equipped with lithium batteries that do not have such a feature. Moreover, deep charge-discharge cycles are extremely detrimental to the operation of such batteries.

Very often there are advisers that say to delete the calibration file of the Android battery called batterystats.bin. In fact, this does not help, because it only contains data that shows the level of energy consumption of certain applications.
