Calibrate the battery through the engineering menu. How to calibrate the battery on Android

Smartphones and tablets running Android OS have the same problem for many users. After a short period of time after purchasing the device, owners begin to notice a fairly significant decrease in battery life devices. As a rule, the first thing that comes to mind is to purchase new battery, but before you decide to take this step, first try to carry out a simple procedure to calibrate your battery, and after that, if this does not give results, you can safely go for a new battery.

If you began to notice that your smartphone began to discharge faster or turn off completely when the charge indicator did not have time to fall below 70%, then the so-called “Memory Effect” has occurred in your smartphone’s battery. Its essence lies in the fact that if the battery is not fully charged, its capacity decreases over time. The battery seems to remember to what limit it needs to be charged. You can “retrain” it using calibration.
Calibration in general meaning means bringing something to an optimal state. In the case of smartphones, it means improving battery consumption in order to increase its operating time.

When should you calibrate your battery?

Before you begin the calibration process, you first need to make sure that you really need it. When is battery calibration necessary?
As already written above, there is a noticeable decrease in the operating time of the device. For example, if after purchase your smartphone worked for 3 days in a row; in the second month - after charging it began to withstand 2 days, and so on. This all indicates that your device’s battery is not working properly and needs calibration.

The second case is more rare, but also occurs. Automatic shutdown of your smartphone or tablet even after being fully charged. This problem is extremely rare, but can raise quite a few questions for a novice user.
So, if you are sure that you need to calibrate, then let's get started.

This method does not involve installing any applications; all you need is a phone and a charger.
The first thing you will need to do is charge the battery until the screen of your device shows that the charge is 100%. After this, unplug the charger and turn off the phone. Connect the charging cable to the switched off phone and plug it into the network again until a signal appears on the screen of the switched off phone indicating that the battery is fully charged.

The next step is to turn on the phone and disable the ability to dim the screen backlight in the settings (usually in Android, this is: display settings - sleep mode). When your phone stops going into sleep mode, start charging the battery again to 100%.
Disabling sleep mode is necessary to allow your smartphone's battery to drain faster, thereby causing your battery to drain faster. So, after the smartphone is charged, leave it to discharge with the display on.
When the smartphone is discharged, charge it again. This should be enough for your smartphone to start using energy correctly again.
This is where the “manual” calibration method ends. Don't forget to turn Sleep Mode back on.

There are a huge number of applications aimed at improving the battery life of your smartphone. Today we will focus on one of them, the most popular -.
The sequence of actions for this calibration method will be as follows:
First, you will need to launch this program and connect the device to the charger.
After the phone is charged to 100%, you will hear a characteristic squeak, but do not rush to remove the charger, you will need to wait another 1 hour from this point.

After another hour of charging, in the application menu you will need to press the “Calibrate” button and wait for the procedure to complete.
After everything is completed, you can remove the charger from the network and reboot your device.
This completes the calibration process using the application. If you did everything correctly, then the memory of your battery controller has been reset. This method The good thing is that it does not require any extraneous actions from you, the program does everything itself.

Before you begin the process of calibrating your device using this method, you will need to know the capacity of your battery. This can be done quite simply by looking under the cover of your device, at the battery itself, or by searching for information on the Internet. Battery capacity is determined in mAh.
Once you know exactly the capacity of your battery, you can begin installing the program. Its essence is that it will show you in real time the amount of charge in your battery. All you have to do is bring this indicator to the level to which your battery is designed.
When the charge reaches its maximum, you will need to unplug the device and reboot it, thereby letting the device understand what the real capacity limit actually is.

If after the first such procedure you do not feel any special results, then try 5 full cycles of charging and discharging the battery. After such actions, the device with 100% confidence will take this indicator for granted and will not discharge ahead of time, and you will get what you needed - battery calibration.

Advice: After purchasing a new device, be sure to perform 5 complete charge and discharge cycles of the device’s battery. This will significantly extend the life of your battery.

Battery calibration on Android with ROOT rights

This method is used extremely rarely by users, but also has a right to exist.
In order to calibrate the battery in this way, you need to:
The first thing to do is bring the phone to Recovery Mode and go to the Additional section. In it, you will need to press the “wipe battery stats” button. This press will clear any calibrations ever made by you or your device's system.

The second step is to completely drain your device's battery. After your device is discharged, charge the device until it is fully charged without turning it on.

These two manipulations should be enough to let your device understand what you require from it. If you want to consolidate the result, then after fully charging the device, without disconnecting it from the network, perform additional calibration in the program. This way, your device's battery will be calibrated at its best.

Advice: Try to charge your device via USB as little as possible. This can only be done if you do not have access to a regular outlet.

To summarize: Don't forget to monitor the condition of your device, including the battery. After all, quite a lot depends on it. Calibrate your battery regularly and then your device will please you much longer.

Modern smartphones without a battery cease to be mobile, being “tied” to an outlet. Depends on the condition of the battery reliable operation gadget. But there are ways that will help boost and extend the life of the battery on your phone or Android tablet. How to find out the energy capacity of the drive on Android and calibrate it, which determines the service life, you will learn further.

The essence of the problem with the battery in the gadget

Perfect mobile device, while remaining turned on, should consume little energy - a maximum of one milliampere of current per hour. The capacity of a modern battery is measured in thousands of milliamp-hours. This is how the simplest mobile phones work, in which there is nothing except calls, SMS and a system clock - this is, for example, the simplest children's phone"Beeline A100" or the ancient Nokia 3310 mobile phone. A full-fledged gadget with Android system, of course, cannot be compared with these mobile phones.

The essence of the gadget's energy consumption problem lies in self-starting Android processes and services. In second place in terms of battery energy consumption are numerous programs that independently user installed. Battery consumption can also be affected by Android version, not brought to mind.

How to turn off unused features on Android

Be that as it may, the consumers of battery energy are the following hardware and software:

too frequent calls, long conversations on the gadget;
active movement of the subscriber within the network coverage area, switching between 2G/3G/4G networks;
SMS/MMS sent in batches per day;
backlight brightness;
Backlight levels help the device not waste energy on it
Frequent calls from third-party applications to GPS background; GPS services open by command: Settings - Location
auto screen brightness (light sensor is activated);

Give the command: Settings - Screen and check if auto-rotate the image is enabled
auto-rotate the image on the screen (the motion sensor is activated);

The setting is also opened by the command: Settings - Screen
compass;
vibration feedback on-screen keyboard;
Go to Settings - Language & input - Keyboard settings
Internet distribution via Wi-Fi to other devices; Give the command: Settings - More - Modem mode - Access point
connecting other gadgets and accessories via Bluetooth;
Give the command: Settings - Bluetooth and check if the module is turned off
connection computer equipment and accessories via an OTG/microUSB adapter.

All these consumers additionally load the processor and RAM, and use peripherals (controllers and wired and wireless communication modules of the mobile device).

How to check your device's power consumption

Give the command “Settings - Battery”.

A gap in the usage chart means the gadget is turned off when charging

When the device is turned off, it does not keep track of battery energy consumption - this is only possible when the gadget is active.

Practical measures to overclock the battery

Mobile device batteries can be recharged or recalibrated.

Calibrating the battery on an Android smartphone

Calibrating the battery controller is necessary for the gadget to access 100% of the battery capacity. Before calibrating the battery, you don’t have to do anything additional actions(shutdown Android animations, switching the device to airplane mode, etc.). The “swing” of the battery is as follows.

Discharge the battery to 0% so that the smartphone or tablet turns off on its own.
Wait after discharge for up to 5 minutes. This will allow the battery to “settle”.
Charge the battery with a standard charger to 100%. Do not turn on the gadget until it is charged.
Wait again up to 5 minutes after charging. It is allowed to disconnect the battery during this time (if it is removable). Before removing the battery from the gadget, turn off the charger.
Repeat the above steps until the battery is calibrated. Most often, 2–3 help full cycle discharge-charge.

Manufacturers also recommend maintaining the first charge for up to 12 hours, without resorting to downtime between discharge and charge. But this recommendation is not entirely correct - it is a deliberate violation of calibration technology so that people change batteries more often.

After calibrating the battery, you can use your mobile device as usual.

How to “boost” a battery

Battery boosting is done to ensure that it reaches its maximum resource - and lasts as long as possible. IN modern devices lithium-ion (Li-Ion) or lithium-polymer (Li-Polymer) batteries are used, which, although devoid of the “memory effect” (unlike previously used nickel-based batteries), can be “boosted” again.

Before connecting charger it is useful to make several attempts to connect to a smartphone or tablet full discharge battery Often in Android devices, when you try to turn on a discharged gadget again by holding down the power button, a vibration signal is briefly triggered up to two times per second. Hold the power button (or hold it down with something) until the vibration signal in the gadget starts to sound less and less often - and soon it stops for a long time. This will cause the voltage on the controller to drop to the minimum threshold perceived by the device.

Old, “worn out” batteries last for years and beyond if they are not loaded. unnecessary programs and Android features.

Do the following.

After disconnecting, try turning on the gadget again.
Make several attempts to turn on until the device display stops responding.
Remove the battery from the device for a couple of minutes and let it build up the voltage a little (without recharging!).
Insert the battery back and hold down the power button again until the vibration signal emitted when you turn on the gadget completely stops.
After making several such attempts to completely discharge the battery, connect the charger to the gadget and let it charge. The device itself must be turned off.

The build-up is achieved by reducing the lithium metal crystals in the working layer of the battery under the influence of fluctuations in battery voltage in the maximum permissible range of values (from 2.5 to 4.2 volts). Do not overdo it - discharging lithium-ion batteries too deeply (up to 0–2.5 volts) and leaving them without recharging in this state will lead to an irreparable loss of their capacity.

If necessary, repeat the calibration of the battery controller according to the instructions above.

Difficulties encountered during battery operation

Some manufacturers, in the interests of their own commerce, resort to additional tricks.

Firstly, it wears out the battery as quickly as possible. Little-known ones especially save on materials Chinese companies or completely underground producers.

A “disposable” controller in the battery itself behaves as follows. After 3-4 years (or up to 1000 discharge-charge cycles), it may one day turn off forever, generating, for example, a “breakdown” pulse and thereby self-destructing (if the controller itself is something special), but without causing harm to the device itself. The battery and, possibly, the gadget itself will need to be redesigned. Fortunately, this measure is one of the last resorts.

“Setting” the battery on glue, from which it is difficult or impossible to remove it, is sometimes used in the most expensive smartphones and Android tablets. This is reminiscent of gluing the battery in the iPhone 5x/6(s).

Additional locks, cables and other “tricky” devices make it much more difficult to remove/replace the battery.

The service life of a battery cell without a controller (this requires reworking an outdated gadget using a soldering iron) can stretch for 10 years or more until the battery is somewhat reminiscent of a capacitor, capable of holding only a very small charge - 1-2% of its original capacity. Such elements are useful only in all sorts of homemade products, which are unlikely to have anything to do with cellular communications and mobile data transmission. They require slow discharge-charge according to a special algorithm, unattainable in conventional chargers that have not undergone any modification, and regular monitoring of the condition of such batteries.

Completely “dead” cells that do not respond to attempts to recharge them (this is due to the steady aging of the electrochemical material of the battery), stubbornly showing 0 volts on the multimeter, are disposed of in accordance with local legislation and environmental protection requirements.

How to extend battery life on an Android phone or tablet

Ways to save battery power are purely software. They do not apply to interference with the “stuffing” of the gadget (for example, pulling out some of the display backlight LEDs, removing the vibration motor, etc.). Most of these settings are in the main menu Android settings and were discussed above.

Optimizing Energy Saving in Android

Don't keep apps you don't use on your device.

Close unused this moment programs - this will clear up the RAM.

Unnecessary applications are closed by swiping to the right

Turn off unused functions ( unnecessary applications, Android processes and services, “extra” wireless communication, bright backlight at night, operation of built-in sensors, etc.). Root access will also help to permanently block unnecessary applications.

Root will help you disable unnecessary programs and services

Avoid places where mobile phones do not receive reception or constantly lose the network (long distances between populated areas, basements and underground garages, shielded rooms in secret laboratories and radiation diagnostics/therapy departments in hospitals, sensitive areas, etc.). Try to use one communication standard, for example, 3G.

Give the command: Settings - More - Mobile networks

If the charging device displays incorrectly on the screen or the device turns off prematurely due to battery wear, recalibrate the battery using the above method.

Maintenance of the battery and the device itself

Give the battery serial “runs” with a full discharge and charge - at least once every six months in order to “boost” the battery capacity and calibrate its controller.

The internal battery controller must be matched charging voltage. If the element itself is charged at a voltage greater than 4.2 volts, it is regularly recharged and gradually swells. This is noticeable after one or two years of intensive use of the battery. Over time, such a battery will no longer fit in the gadget and will protrude back cover(it will stop closing, its latches will fly off). If there is a significant discrepancy between the output voltage of the controller and the element itself, the battery simply explodes. In the 2000s, when the market Chinese smartphones As soon as it began to develop intensively, a swollen battery was a frequent occurrence. Over the years Chinese manufacturers They began to more accurately “tailor” controllers to Li-Ion elements - but from time to time defective batteries are produced. Change such a battery as quickly as you can.

Dirt on the battery contacts and terminals of the device, although they are gold-plated (gold does not oxidize), is additional electrical resistance, from which the charge may be displayed incorrectly by the gadget. Clean such stains with medical alcohol.

Try not to unnecessarily pull the battery out of place, even if the SIM card and/or memory card slot is located underneath it.

It is permissible to use chargers with lower power - but not vice versa. Charging too powerfully will cause significant heating of the battery and the gadget itself. Do not expose the battery to prolonged heat above human body temperature (36.6). At 40 degrees or more, modern controllers turn off the charging current until the battery cools down again to an adequate temperature - elevated temperatures accelerate battery wear.

If the microUSB connector is dirty, battery charging may be “drip”, intermittent, or the charging current may not flow into the battery at all. Most often this happens if the gadget is used carelessly and in polluted air for several years. Clean the microUSB socket with a toothpick, a sharpened match, or blow with a vacuum cleaner turned on at maximum power.

Proper battery care will extend its service life. But if no restoration helps the battery, replace it.

Problems with your smartphone's battery are probably one of the most common occurrences, and that's why we are looking for new ideas and suggestions on how to better deal with this problem. Battery consumption may be uneven and you need to figure out where the problem is. You can also try calibrating your Android's battery, which can significantly improve performance, if that's possible with your phone.

In this article, we'll take a closer look at how you can calibrate your phone's battery.
Our first suggestion for improving power consumption will be our article "Saving battery power by various smartphones" Even after these tips, the problem still persists and then it is time to calibrate the battery. The biggest battery problem is when it runs out extremely quickly, or the phone simply won't turn on.

Before replacing the battery, try calibrating it. This may be the only way that is used in most cases!

Battery calibration - what does it mean?

Every Android phone has a battery app that displays all the necessary battery stats for your phone. The app is very informative as it shows the battery percentage, battery life and battery consumption. various applications using your battery resource.

In some cases, when your battery is not calibrated, this application may produce errors in statistics. Battery calibration can correct this problem and hopefully improve performance.

Calibrating your Android's battery - on non-rooted phones

First, don't forget to check the battery capacity. If you're not sure, look up your phone's battery specs online. You can find detailed specifications model of your phone, on the website of your phone manufacturer.

After that, look for an app called "Battery Monitor" " You can find the application to download at Google Play shop.

The unique feature of this app is that it will show you the charging parameter in milliamperes (MA). Of course this is a big help when you need to charge the battery to a certain level indicated by the battery capacity. Upon reaching required level, just unplug your phone, turn it off and turn it on again. If everything is done as noted, your phone's battery will be charged 100%

An alternative way to calibrate your Android's battery:

Fully charge the battery and once this is done, simply turn off the phone.

After turning it off, plug it back into the charger and charge your phone to 100 percent again. You'll know your phone is at 100 percent charge when you see a green light on your phone.

Now turn your phone back on. Go to the display settings tab and select the option to keep the screen backlight on. Now connect your phone to the charger and charge it to full 100% again.

Finally after this, turn off the phone and let the battery drain to 0% and the phone will turn off by itself. This long process, but it should be done this way for proper operation calibration process.

What can drain your phone battery?

It is worth noting that modern phone firmwares are full-fledged mobile devices. OS. This means that while the phone is running, “background” processes are required, such as: SMS messaging service, Text input service, Antiviruses, etc.

Accordingly for work background processes it is also necessary to spend on them both power central processor, random access memory and of course - battery charge.

During “active” use of the phone (for example, starting various programs: Internet browser, Games, Bank account access programs, Mail programs etc.) we recommend restarting your mobile phone. To do this, you need to press and hold the “Power” button of your phone and select “Restart”.

If all else fails

After long term use of your phone - the battery becomes unusable over time. But even from this situation there is a way out, for example:

Battery calibration results

After a somewhat complicated battery calibration process there is hope of giving your charger a new one life cycle. Have you tried any of the methods mentioned above or do you have your own? own way optimizing your Android battery?

We'd love to hear your thoughts in the comments below.

IN certain moment a smartphone or tablet may begin to discharge much more quickly than before. Our website already explains why the device begins to discharge quickly. If nothing helps you, do not rush to run to a service center and replace the battery with a new one; it is quite possible that you just need to calibrate the battery.

What is battery calibration on a phone or tablet?

Battery calibration is measuring the capacity and, roughly speaking, editing the battery. As a result of calibration, the battery is used more efficiently and its service life can be significantly extended.

Signs that your battery needs calibration

It takes a long time to charge the device, for example, not a couple of hours as before, but 4-5 hours.

Significantly shorter operating time of the device on one charge.

Even with long charging The indicator does not want to show 100% charge.

The device turns off when there is no power, although you do not receive any signals from the battery indicator.

If you encounter this kind of trouble, it makes sense to try calibrating the battery. True, it is initially worth considering other options. Here's an example from real life: a user updated his smartphone over the air to new version firmware that was just released for his device. After the update, he noticed that the smartphone began to discharge quickly. In this case, the problem arose precisely because of the firmware, since after a couple of days an additional update was released that solved the problem of fast discharge. These are the types of cases that need to be taken into account.

If you do decide to calibrate, let's talk about it.

Manual calibration

In this case, no third party applications are not used, only the device itself and charging are needed. Ruth, that is, superuser rights, is also not needed.

The device needs to be completely discharged.

Then start charging it with it turned on for 8 hours.

Turn off the device and continue charging it for another 2 hours.

Disconnect the device from charging, turn it on for 2 minutes, turn it off and connect it to charge again. This time charge for 1 hour.

Calibration is complete, turn on the device.

Calibration using software

This option is suitable if you have it installed on your device. Download the Battery Calibration app from Google Play Market, install and run.

When you launch it for the first time, you need to provide root rights, otherwise the application will not work.

And here further instructions, which is not mentioned everywhere:

Connect your device to the charger.

Wait until it charges to 100%.

Click the Battery Calibration button.

Unplug the charger.

Discharge your device before turning it off.

Charge it to 100% without interruption.

In fact, the application deletes system file batterystats.bin and then the system automatically generates clean file. Any old information, which could cause the battery to work incorrectly, will not be present in this file.
