How to disable the battery controller in Android. Android Battery Calibration

Home / Windows 7

Users have virtually no problems with the new gadget - they just need to install necessary programs and applications, and enjoy their work. But no matter how expensive and high-quality the device is, over time it will begin to lose its qualities due to wear and tear of parts. The first noticeable deterioration in performance concerns the battery, which begins to discharge faster than usual.

You can try to correct this drawback by calibrating the battery. You will learn how to do this in this article.

What is battery calibration?

In any device with an operating system - a tablet or smartphone - a special controller is responsible for the performance of the battery. It controls the discharge and charge limit of the battery. The longer a battery is used, the more it loses its main property - holding a charge. This indicator may also be influenced by other factors, for example, installation new firmware, launcher, etc.

Calibration is the process by which reset occurs. standard settings, while the battery charge and discharge levels are set in accordance with its condition. In most cases, the battery lasts longer after calibration.

How to calibrate the battery?

Calibration requires a special program designed for Android OS. Battery Calibration is considered the most popular, although there are many other utilities. There is a second option – a physical calibration option.

Method 1

Download the Battery Calibration program and install it on your device.
Launch the utility and connect the charger to the device.
Wait until the battery is fully charged - 100%, and you will hear a corresponding sound signal.
Do not unplug the charger immediately, but wait another 1 hour.
IN open program Click on the “Battery Calibration” button and wait for it to complete.
Unplug the charger and restart your smartphone (or tablet). This completes the calibration process - thanks to the utility, the controller memory was reset, and the current technical parameters batteries.

Method 2

To avoid installing additional applications, you can use this method. Even if it turns out to be ineffective for your device, no damage will be caused to the gadget.

Follow these steps:

Turn on your Android device and connect it to the charger, keeping it in this state for at least 8 hours (for a tablet – 10 hours);
Turn off charging;
Turn off your smartphone and charge the battery for 1 hour;
Turn off charging;
Turn on your smartphone for a minute or two and then turn it off;
Charge the battery again for 1 hour;
Disconnect charging, turn on the device. The battery life of your Android device will increase.

It should be remembered that during calibration the battery is not restored - only the settings are changed. Thus, these methods are ineffective for an old and a completely new battery.

When a smartphone is new, its user cares little, because the gadget brings a lot of positive emotions and copes well with the tasks assigned to it. But everything is not forever, and technology has such properties as aging and wear of parts and deterioration general work. Probably the very first thing that begins to irritate the user is battery phone. And in today’s article we will look at several methods on how to improve its condition by calibration.

What is battery calibration and why is it needed?

Every smartphone or tablet based on the Android or iOS platform has a special controller that is responsible for the battery charge and discharge limits. Over time, the battery loses its ability to hold a charge; this can also be observed when changing the firmware version or adding patches or launchers.

So, the battery calibration process resets the default settings and sets the charge and shutdown levels according to the current technical condition of the battery. As a rule, this has a positive effect on the duration and correct operation of the battery.

Battery calibration on Android

Everything is simple here, calibration in the Android platform is done using special utility or programs. We will look at the two most popular of them - Battery Calibration and Advanced Battery Calibrator.

How to use Battery Calibration

First you need to download the program for free from the official website here. After installation, run the utility and follow the instructions:

With the program window open, connect the charger to the smartphone or tablet;
We wait until the device is charged to 100%, then a beep will sound;
After fully charging, you need to wait another hour;
Press the Battery Calibration button and wait for the procedure to complete;
Disconnect the device from the charger and reboot the gadget;
The entire procedure is completed.

The program will reset the controller memory and enter new technical values.

How to use the Advanced Battery Calibrator

Similarly, first we download the utility here, after launching we need to accept the terms license agreement and follow the instructions:
Connect the charger when open window programs;
Click the Calibrate Now button!
We are waiting for the process to complete;
When the procedure is complete, turn off the device;
With Android turned off, wait until the battery is fully charged;
Disconnect the charger and turn on Android.

All calibration is completed.

Remember! When Android is turned off, the time for a full charge during the calibration process is at least 6 hours for smartphones and at least 10 for tablets.

Battery calibration on iPhone iPad

Devices running on the iOS system have always had a long service life compared to Android. Therefore, users are much less likely to ask about calibration.
At the time of writing, special programs as for Android it was not, and the whole process comes down to standard methods of increasing service life: completely discharge and charge for at least 10 hours.

If you still have any questions regarding calibration, we will be happy to answer them in the comments below the article.

Problems of rapid loss of battery charge, uneven indication of the state of charge, sudden discharge and shutdown of the device are very common. Sometimes they are a consequence of battery wear and are irreversible, but in some cases you can try to correct the situation by calibrating the battery. It's not very difficult; you can calibrate the battery on Android in several simple ways.

It is important to remember that none of the methods is a panacea. If there is physical degradation of the lithium cell of the battery, it is almost impossible to help it. Even if you try to replace the “jar,” a record of battery wear may remain in the controller’s memory, which can only be reset by the programmer.

In what cases is there no way to calibrate the battery on Android?

Battery calibration is impossible, useless, and sometimes dangerous if the lithium cell has suffered physical wear and tear. A characteristic sign of this may be a rapid loss of charge even on an inactive smartphone. Typically, the charge indication is not affected in such cases. The percentages melt before our eyes, but the decrease in the indicator is smooth, without jumps of a dozen or two percent (for example, immediately from 90% to 60%).

A physically worn out battery charges very quickly, it can reach 100% in just half an hour. If your smartphone suffers from such symptoms, only replacing the battery with a new one will help. Another sign of wear is a bulging cell. In devices with a removable lid, it is visible to the naked eye.

In devices with a non-separable design, signs of swelling may include peeling of the back panel, a bulge on it, or spots appearing in the middle of the screen. In this case, calibrating the battery using charge-discharge cycles is not only useless, but sometimes dangerous. After all, a swollen battery can overheat and spontaneously ignite or explode.

What methods will not work to calibrate the battery?

Modern controller Android battery-smartphone is a complex device, with own memory, where battery information is stored. It operates independently and maintains service statistics without impact from the OS. The system itself does not have access to the memory of the battery controller, and therefore there are no miracle applications that can calibrate the battery on Android in a couple of clicks.

Calibration methods such as deleting the batterystats.bin file are less effective. Firstly, this method requires root rights, which are difficult for an ordinary user to obtain on most modern smartphones (2015-206 and newer). Secondly – this file only stores data on battery discharge statistics at the OS level, but is not associated with the battery controller's own memory. Deleting this file can only help in some cases, if we are talking about a failure in Android system. Deleting the batterystats.bin file cannot eliminate failures at the level of the internal battery controller.

Programs designed to calibrate the battery and require root access are mostly designed to remove the same batterystats.bin. The only difference is that this file does not need to be searched and deleted manually. Therefore, it is logical that most of these programs also do not give the desired effect.

How to easily calibrate your smartphone battery

Lithium battery cells used in smartphones do not have a memory effect. But, nevertheless, sometimes charge display errors occur, caused by malfunctions in the controller, but which are reversible. In such cases, the long-known procedure of performing several discharge-charge cycles can help.

To calibrate removable smartphone batteries, you can use independent frog-type chargers. Their advantage is that such devices charge batteries with weak currents and do not depend on OS commands. Therefore, if the battery is removable, it is better to charge it with such a device, outside the smartphone.

Step-by-step smartphone battery calibration

Discharge the battery until automatic shutdown smartphone. It is better to discharge without a very high load, for example, playing a video, at room temperature (lithium drains faster in the cold).
Wait a few minutes and try to turn on your smartphone.
If the gadget turns on and displays the remaining charge, discharge it before turning it off again.
If the gadget no longer turns on, put it on charge. It is advisable to use a low-current power supply that does not support fast charging.
Wait for the charge to replenish to 100% and the signal to fully charged, keep the battery charging for another 10-20 minutes.
Unplug the charger and plug it back in a little later.
If the smartphone immediately reports a charge of up to 100%, turn it on. If it reports charging again, wait for the notification of 100%, repeat step 6.
After turning on the smartphone, discharge it using a stable medium load (for example, a video player).
Repeat steps 1 – 8 2-4 more times.

If the calibration failure was reversible, repeating several cycles of gentle charging and discharging with small currents should cause the battery controller to return to normal operating mode. If this does not help, other methods will most likely also be useless.

Conclusion

Before calibrating the battery on Android, make sure that it does not show signs of physical degradation. Do not overcharge/discharge during calibration. If 3-5 cycles did not bring results, then 25 will not be of any use. Moreover, during each cycle the battery loses some fraction of a percent of its capacity. After all, the average life of a lithium cell is only about 1000 cycles before serious loss of capacity. Because of this, you should not resort to the calibration procedure too often.

Among other things, it is important to avoid excessive heating during the charging and discharging process. It is advisable that the temperature of the “can” be kept within +40 degrees. If it is more, it is dangerous; in addition, overheating may be the reason for the controller to malfunction. You should also not load your smartphone at temperatures near zero or below. In the cold, lithium quickly loses its charge, and even a fully functional battery can suddenly turn off at 50% of its capacity.

Modern mobile devices they just look simple. In fact, each of these compact devices - tablet, smartphone or just mobile phone- represent a whole complex various systems. Some of them have very high energy consumption. For a tablet, such a module is a block, just like for a smartphone. It is not surprising that even with a large battery capacity, the charge does not last long. You can often come across such a thing as calibrating a tablet battery, which is said to be necessary and even inevitable. Let's see if this is true.

There are situations in which the battery may need to be calibrated. The short list is as follows:

The device began to work for much less time;
After full charging, the indicator on the screen does not show 100% level;
The system displays a decrease in battery capacity in strong jumps;
The tablet turns off due to lack of power, although the indicator does not indicate that the battery is completely discharged, and no warnings are issued.

There may be several explanations for this behavior. Some cases are quite expected - experiments were carried out with the device, for example. Others are not so obvious, and battery calibration may actually be necessary. A short list of symptoms and preliminary actions can be summarized as follows:

the firmware with which the system was recorded, which has different battery usage statistics, has changed;
the battery has been changed and has different parameters;
The tablet battery fails;
the power and battery charge controller is acting up;
the charger does not provide the necessary parameters;
The battery controller gives incorrect readings from the sensors that Android uses.

There is no point in compensating for the last four points. Needs renovation. But the whole catch is that the behavior of the tablet is difficult - in the electronics or the software part. Therefore, before you go to service center, it is better to resort to simpler methods.

Most popular method

If the firmware is changed, the best answer to the question of how to calibrate the battery on Android will sound very simple. You need to reset the battery usage statistics and force the system to create the file again.

There is a popular and quite widespread - the Battery Calibration program. It acts radically and simply, forcing Android to recognize the battery as the first and only one and set the power system parameters in accordance with its characteristics.

The application will need root access to delete statistics. Battery Calibration can be downloaded from PlayMarket, it is easy to install and does not require configuration. You won’t have to spend a lot of time figuring out how to calibrate the battery on your tablet either. looks like this:

Install Battery Calibration;
Fully charge the tablet when turned off;
Turn on the device and launch the program;
Before us is a single button. Click;
Battery Calibration will ask for a superuser name.

Video on how to use the Battery Calibration app:

By specifying the required data and confirming the choice, the user initiates overwriting the statistics file and creating parameters that are responsible for only 100% battery charge. Then the system will do everything itself according to the readings of the battery controller.

Meticulous and attentive users began to ask questions to the “author” - Google. They concerned, first of all, the effectiveness of using Battery Calibration and similar programs. As expected, the company recognized the method as the least effective, giving an acceptable result only when the following factors are combined:

normal battery condition;
correct operation of the power controller;
reliable battery sensor readings;
regular work charger.

The method proposed by Google to calibrate the battery on Android is quite complicated. Judge for yourself:

or smartphone. The process must continue for at least 8 hours, even if the system signals that charging is complete. The device must be turned on;
Disconnect the charger or unplug it from the outlet. Turn off your tablet or smartphone;
Start the charging process again and continue for an hour;
Disconnect the charger and turn on the tablet or smartphone. Keep it in this state for a minute or two;
Turn off the device and charge again. Continue for an hour;
Physically disconnect the charger cable and turn on the smartphone or tablet.

It looks strange at first glance. But everything is rational and simple. In this way, statistics are recreated and hardware parameters are adjusted as much as possible to suit all conditions. From a physical point of view, everything looks like this:

after the first point, the battery gains capacity, which corresponds to the maximum controller readings recorded in system statistics;
the second point relieves the load, all consumers are disconnected;
the third point performs additional charging with optimal current and voltage under hardware control of the power chip;
the fourth point forces the system to update statistics, since sensor readings may not correspond to previously recorded ones;

The actions of the fifth and sixth points are control ones. They are intended mainly for complex devices whose power management systems use statistical data operating system. The last two steps allow you to truly charge the battery completely. And turning on the smartphone or tablet again records a new maximum of indicators in the statistics if they have changed.

As you can see, this can be done periodically if the battery loses capacity.

Other ways

You can find several more options for action. One of them is a prototype of the technique proposed by Google - repeated charging/discharging of the tablet. The same method of collecting new statistics, only not as accurate.

There are a number of programs similar in principle to Battery Calibration. But resetting statistics parameters, as described above, does not always work well.

Which display the indicators of battery monitoring sensors in numerical form. One of them is Battery Monitor. It displays the current battery charge in milliamp-hours. It is recommended to charge the battery until the program readings match the maximum capacity written on the battery.

The program works great, but anyone who decides to learn how to calibrate the battery on Android is likely to encounter problems. If we are talking about malfunction power controller or a drop in battery performance, then in accordance with the recommendations you can repeat the charging/discharging process forever. And to no avail.

What to do?

In order not to wander around in three pines, wondering why the tablet began to work for less time or behaves incorrectly, use the method proposed by Google. This tablet battery calibration is completely safe.

Perhaps the problems will disappear; in any case, the repetition of similar symptoms after some time will clearly signal hardware problems. But if you carried out experiments: changed the firmware or changed the power management parameters, resetting the statistics using Battery Calibration is acceptable and will give good results.

It's no secret that modern phone users often have problems with the battery life of Android devices. A smartphone or tablet does not last long. This can lead to a number of negative consequences. Battery calibration can improve the functioning of the problematic component. But what will it take? Is it possible to carry out the procedure yourself? How to calibrate the battery on Android? All this will be discussed further below.

Signs of Problems

In fact, it is important to understand when the user really has problems with the battery on the phone, and under what circumstances the gadget works normally. There are several signs that suggest you should consider calibration.

The first scenario is that the smartphone or tablet begins to turn off on its own when it has a charge. Even 1% is usually enough for battery life. Therefore, you will have to think about how to calibrate the battery on Android.

The second sign that it is recommended to pay attention to is the battery life of the device in offline mode. For example, previously a smartphone could work for a week, then 5 days, and after a month or two - 2-3 days. This behavior is a sure sign of an incorrectly configured battery.

Calibration is...

What is calibration? Electricians are probably familiar with this term. In dictionaries, the concept is deciphered as bringing the device to an optimal state. In other words, this is the setting of a particular device.

In the situation under study, we are talking about setting up the smartphone/tablet battery so that it consumes energy optimally. So how to calibrate the battery on Android?

On your own or with help

To answer the question posed, everyone must decide for themselves exactly how they plan to act. You can calibrate the battery yourself without much difficulty. But beginners or people who are concerned about the safety of their devices are not recommended to take risks.

The point is that if you do it incorrectly, you can end up with a battery that holds too little charge. And this will lead to the loss of functionality of the gadget. Therefore, if there is the slightest doubt, it is recommended to simply take the device to a service center. There, for a reasonable fee, they will tune the battery with 100% safety.

Calibration Methods

However, it is still necessary to know how to calibrate the battery on Android (manually or not - not so important). In fact, there is nothing difficult or special about the procedure. The main thing is to follow the instructions. They will be given below.

In practice, calibration can be done in several ways. Namely:

with root access;
without root.

You can also classify the work ahead as follows:

manual calibration;
use of additional programs;
working with the engineering menu.

How exactly to proceed? Every person should think about this in advance. Indeed, the success of calibration often depends on the chosen technique. In practice, when carried out correctly, all of the above methods give quick and good results.

CurrentWidget

How to properly calibrate the battery on Android? The first technique is nothing more than working without root. Just a few minutes - and it's done!

The algorithm of actions boils down to the following steps:

Determine the battery capacity. To do this, you need to study any review of your existing smartphone or tablet. The battery capacity in mAh will be written there.
Download from Play Market an application called CurrentWidget: Battery Monitor.
Install the downloaded program.
Charge the battery to the standard specified by the manufacturer. To do this, the device is connected to the network.
As soon as the desired result is achieved, turn off the phone/tablet. Turn it on immediately.

In fact, such a technique is not always effective. But it is often recommended for novice users. What to do if the method did not help?

Hard Reset

How to calibrate the battery? On Android versions of the OS, there are several methods to bring your idea to life. For example, to act using the so-called Hard Reset.

What to do if the previously proposed method turned out to be useless? You can try to fix the battery like this:

Charge and discharge the device completely 5 times.
After the last charge, you need to unplug your phone or tablet and wait a few seconds (about half a minute).
Perform Hard Reset. To do this you will need to go to engineering menu. Each device has its own method of operation. As a rule, it is enough to hold down the power and volume buttons for a few seconds. Next, select the appropriate operation.

The manipulations performed will help the device perceive the resulting charge level as 100%. Thanks to this, the battery will start working properly.

No apps

How to calibrate the battery on Android without root and additional software? The next technique differs in that you will need to work exclusively with the charger and battery. No additional actions are needed.

Instructions for setting up the battery look like this:

Fully charge the device's battery. After this, be sure to unplug the gadget and turn it off.
Connect the charger cable to the disconnected tablet/phone and charge the device until the LED indicator turns green (indicates 100% charging).
Turn on your phone and stop using it automatic shutdown display. On Android, this option is usually disabled in the “Display Settings” - “Sleep Mode” menu.
Charge your device to 100% again with the screen on.
Now you can turn on sleep mode and work with your smartphone.

The actions taken are calibration. Only all of the listed options provide for the absence of root. With root you can configure the battery slightly differently.

Battery Calibration

How? How to calibrate a non-removable battery on Android? Exactly the same as a regular battery. Settings with root rights are considered the most effective. For example, using additional software.

The calibration instructions look like this:

Download and install Battery Calibration. The best way to do this is using the Play Market.
After installation, fully charge the battery.
Open Battery Calibration and check the battery charge. You need to charge your device to 100% in the app.
Click on the "Calibration" button. This should only be done when the smartphone is fully charged.
Reboot the device.

This is where all the manipulations end. But there is another good trick.

Recovery Mode

How to calibrate the battery on Android through the engineering menu? You can use a technique such as working with the device recovery mode.

How Recovery Mode will help you achieve your plans? If you follow the instructions, you can successfully configure the battery of any smartphone.

This requires:

Open Recovery Mode. It turns on if you press simultaneously Home button, as well as volume control. After this, the device’s power key is additionally pressed. Manipulations are carried out with the phone turned off.
Go to the "Advanced" section.
Find there and go to Wipe battery stats.
Reset all previous calibrations. To do this, select the appropriate menu item.
Discharge the phone/tablet until it turns off completely.
Charge the disconnected gadget to 100%.
Turn on the device (without disconnecting from the network) and click on the "Calibration" button in the Battery Calibration program.

Ready! From now on, it’s clear how to calibrate the battery on Android. In reality, everything is simpler than it seems! Many people say that all of the above techniques are very effective. But most often, old batteries are simply replaced with new ones. This way you don't have to worry about calibrating the battery.
