Calibrating the battery on your phone. How to calibrate the battery on “Android”: step by step instructions and reviews. How to do a battery calibration without root access

Sometimes after buying a new Android device or in the process of use, the battery shows unnatural or incorrect values of the remaining charge. There are sudden dips from 50% to 15%, when fully charged it shows 105%, etc.д. This indicates that the information about the current battery capacity is not being transmitted correctly. In this case, you need to calibrate.

By calibration of the battery we mean a forced update of the information about the real capacity of the battery.

When you need to calibrate the battery on Android?

First of all, you need to understand how old your smartphone is. If you’re a veteran from the past who’s still in the days when 32GB of memory in a smartphone was something to brag about, you shouldn’t expect miracles and the method below is not for you. If you bought it a year ago or even less you are on your way to a calibration procedure in the following cases.

The main bell that it is time to do something with the battery will be the device shutting down at 20-30 percent of the charge. Sometimes this value can go up to 50 percent or more. Of course, this is not normal and it should not work like that. Even in the cold it is not considered normal, although many people think otherwise and put up with it. In the cold it is, so to speak, acceptable, but definitely not the norm.

Another sign that the battery calibration is needed is an incorrect display of the charge. For example, a fully charged smartphone may display 90 percent. There are cases when 100 percent charge is displayed, but literally within a few minutes the level drops by 10-15 percent and then works fine. Many users in our Telegram chat complain about cases where the charge fluctuates between 80-100 percent when the smartphone is unplugged. At the same time, the value not only decreases, but can also increase.

In all these cases, you can safely calibrate the battery. it certainly will not be worse. You can look for a good app for this, but as practice shows, they all have their disadvantages and you should not expect much from them. It’s easier to use the “manual” method. over, this method is recommended by Google.

Charge your smartphone properly. it’s almost like a science

How to calibrate the battery of Android-smartphone? And whether it is necessary to do this?

You must be aware that the phones in addition to the usual settings there are hidden. Get advanced information about your device, battery capacity, signal strength, and more. But common users do not get into these settings.

Now let’s figure out if you need to use such an Android smartphone option as the battery calibration function.

The way to calibrate the Android smartphone is described in detail by the authors of Hi-Tech There is no sense to retell the whole process, here is a brief excerpt. Over time, a device’s battery ages, wears out, and loses capacity. Everyone is aware that the battery charge can not be expressed in precise units, such as memory capacity or display diagonal. The designation in percent is relative.

It often happens that over time the phone ceases to understand what level of charge the battery is at, and begins to charge it incompletely. Symptoms. shortened battery life, frequent shutdowns in the cold, etc. Here the authors tell us that the battery can be calibrated.

All of the following procedures can theoretically damage the smartphone battery. Take it at your own risk.

For this purpose it is necessary to charge the device up to 100%, go to the phone application, enter the combination of symbols #0228#. It will open the system menu and you will need to press the Quick Start button. After that, the phone will reflect and then it will give you the battery value. If it’s less than 100%, you need to charge the phone again and repeat the procedure until the desired 100 hundredth percentile is reached.

This is automatic calibration. Manual is a little more complicated:

• Discharge the smartphone to 0% (remember this point, we will explain at the end of the text)
• You need to charge your smartphone to 100% and leave it on charge for eight hours, all the while not using the device
• Then turn off the gadget and leave it on the charge for one hour
• After that, disconnect it from the cable and plug it in again for a few minutes
• Turn the device off again and leave it on charge for one hour

After all the above steps, the battery will be calibrated, the phone can be used as usual. It is believed that this way you can increase the life of the battery. Also, this method allegedly allows you to unlock the hidden features of the phone manufacturer. a drop of conspiracy.

We could not test the theory in practice. Firstly, there was no Android-smartphone nearby, and secondly, to confirm the usefulness of the calibration, you need to spend at least several days on tests. But on the network there is the opposite opinion. The authors of Androidinsider believe that calibrating the battery of a smartphone is harmful. Journalists make several arguments.

First, if the manufacturer artificially lowers the battery capacity of the device or somehow secretly manipulates the smartphone battery, then this will sooner or later become known. Remember at least the Apple case and slowed down iPhones, because of which the company had to apologize and spend money on replacing old batteries. Secondly, proponents of the need for calibration advise to discharge the smartphone to zero before starting the procedure. It’s counterintuitive and can harm your device’s battery. you can’t allow your phone to run out of power completely.

Thirdly, a part of the battery capacity is reserved for system tasks, but this share is so small that it cannot be used to increase the battery life of the gadget.

Whether you’re an advocate of the idea of calibrating your smartphone’s battery or not, remember the simple rules that are universal to all phones on the market and will help extend battery life:

How to calibrate the battery on Android smartphones?

The process described below applies to all Android smartphones. If you have a Samsung device, click here.

• Fully discharge the phone until it turns off.
• Turn it back on and let it turn off.
• Connect the phone to the charger and, without turning it on, let it charge until the screen or LED indicator shows 100%.
• Disconnect the charger.
• Turn on your phone. Most likely, the battery indicator will not show 100 percent, so reconnect the charger (leave the phone on) and continue charging until the screen shows 100 percent.
• Unplug your phone and restart it. If it does not say “100 percent,” reconnect the charger until the screen shows “100 percent”.
• Repeat this cycle until it shows 100 percent.
• Now let your battery fully discharge to 0 percent and let your phone turn off again.
• Fully charge the battery again without interruption, and this is how you should calibrate the battery on your Android.

How do I know if my smartphone needs calibration?

Before the procedure itself, it’s important to know when a battery calibration would be relevant. Here’s a list of situations in which this procedure may help:

• Your phone passes out too early. Charge level is within acceptable limits (5-10% of charge), but the device spontaneously shuts down as if fully discharged;
• After a 100% charge, the level drops with astronomical progression. A prime example. you just unplugged it from the charger, and the charge dropped to 90-95% in a matter of moments;
• Another red flag is that the smartphone continues to run even after reaching a 0% charge level.

Signs that the battery needs calibration

• Significantly shorter battery life on a single charge.

• Even when charging for a long time, the indicator does not want to show 100% of charge.

• The device shuts down when there is no power, although you do not get any signals from the battery indicator.

If you encounter this kind of trouble, it makes sense to try calibrating the battery. True, it’s worth considering other options initially. Here is an example from life: a user has updated his smartphone over the air to a new version of the firmware, which has just been released for his device. After the update, he noticed that the smartphone began to run out of power quickly. In this case, it was the firmware that caused the problem, as an additional update was released a couple of days later that solved the problem of rapid discharge. These are the cases that you need to take into account.

If you do decide to do a calibration, let’s talk about it.

How to calibrate the battery on your Android phone

Your phone‘s battery drains over time. And when it does, you’ll find that your phone is off, even if the battery indicator says you still have plenty of charge. If this ever happens, you need to calibrate your Android phone’s battery.

In this post, you’ll learn how to properly calibrate the battery of your Samsung Galaxy S10, Google Pixel, or any other Android phone you have.

Before you calibrate the battery, you should check the battery first. Remove the back of your phone to see the battery. Remove it from the socket and look for signs of damage, such as a bulge or leakage.

If the battery is no longer usable and will not stand in its slot, it’s time to consider buying a new one. There are various third party battery sellers on the market. Nevertheless, it is recommended to stick to your phone manufacturer and buy the original. There are third-party products that do not meet expectations

Calibrating a broken battery will be a waste of time.

Note: While you’re examining the battery, don’t forget to inspect the charging port and cables. If they are damaged, it may cause your phone to not charge to its full capacity.

Negative effects of a drained battery

The process of calibrating your phone’s battery requires your battery to be dead. Although a necessary step, this process shortens battery life if done frequently. A fully discharged battery should not be a long-term solution.

Batteries are not designed to be drained to zero. Your Android device has measures to prevent this. But the calibration process will force Android to completely drain the battery. However, some users argue that it can be calibrated every three months if necessary.

How to calibrate the battery of an Android phone

Use your phone as normal until the battery runs out and the phone shuts down. After that, turn it on and let the phone power off again. Do this until the phone can’t turn on.

Without turning it on, plug the phone into the charger and keep it on until the battery level indicator shows that it is fully charged.

Once it reaches 100% charge, unplug the charger and restart the phone. Repeat the process until the phone shows that it is fully charged after rebooting.

After that, discharge the battery again until it is completely disconnected. Then charge it to full capacity.

If done correctly, this should calibrate your phone’s battery icon and fix the display on your Android device.

Calibrating the battery via root access also requires discharging the battery. Only this time you will clear the batterystats file.bin.

This method, however, is not recommended by some users, as it requires downloading a third-party application. You could also make the argument that deleting said file doesn’t really do anything.

You would be much better off discharging the battery and calibrating it without ROOT access. If you were interested in this topic, I also recommend reading advice on “How to calibrate the battery laptop.

What is calibration and why do you need it??

If you notice that your smartphone discharges faster or shuts down when the battery indicator does not have time to fall below 70%, it means that your battery has the so-called “memory effect”. The essence of it lies in the fact that when the battery is not fully charged, over time, its capacity decreases. It’s as if a battery remembers how far it needs to go before it needs to be recharged. You can “retrain” it with a calibration. Calibration in general means. bringing something to an optimal state. And in the case of smartphones, it means improving battery consumption in order to increase its lifetime.

Before you start the calibration process, you first need to make sure you really need it. When you need to calibrate the battery? As already written above, a noticeable reduction in the operating time of the device. For example, if after purchase, your smartphone was working for 3 days to a row; in the second month, after charging it started to hold for 2 days, and so on. This all indicates that the battery of your device is not working properly and it needs to be calibrated.

The second case is more rare, but it also occurs. Self-disconnecting your smartphone or tablet even after a full charge. This problem is very rare, but can cause many questions for the novice user. So, if you are sure that you need to perform a calibration, then let’s proceed.

Ways to calibrate the battery

You can calibrate the battery on your smartphone either manually or automatically. In addition, the calibration options involve performing the procedure with or without root rights. Let’s look at how you can calibrate the battery on Android.

Applications and programs for calibrating the Android battery

The automatic calibration method involves the use of specialized software which may or may not require root rights. Any Android battery calibration program can be downloaded from the official Google Play app store or as an APK file from a reliable network resource. A great option is a popular software Battery Calibration, the principle of the tool is to delete the file batterystats.bin, which the system will then create and configure by itself.

To perform the procedure, automating the process is simple. To perform the task using the Battery Calibration app for Android battery calibration, you need to follow the following algorithm (before starting the work you should completely discharge the device, then follow the exact sequence of actions):

• Download and install the program.
• Launch the software, connect the charger to the device.
• Wait until the battery is fully charged (for convenience, the application has a button “Beep when 100% of battery power is available”).
• Do not disconnect the smartphone from the charger for another hour.
• Press the “Calibrate” button in the app.
• Wait for the process to complete, then disconnect the charger.

No root rights are required to perform the calibration this way, and the procedure itself to teach the controller and reset the statistics in the OS is safe. After applying the software it is advisable to let the battery go through several charge and discharge cycles.

Calibrating the battery on Android without root rights

To calibrate the battery you can do without the calibration applications. And there are several methods of adjusting the settings without root access rights. Choose the appropriate option and return the device to its previous functionality.

The algorithm of the procedure is as follows:

• Find out the battery capacity in mAh (for example, by reading the information under the device cover or searching for it online according to the device model).
• Set the software Battery Monitor or Current Widget, which allows you to display the battery level in real time.
• Watch the process of recharging; eventually the charge should reach the capacity specified by the battery.
• When the indicator has reached the limit, disconnect the device from the power supply.
• Performing a device reboot.

As a result the smartphone will determine the real battery capacity. If the procedure has not given the proper effect from the first time, you can perform 5 complete cycles of charge and discharge.

Calibrate the battery manually on Android

You do not need to install any software, just have the device and the charger. To calibrate it proceed as follows:

• Charge the battery fully to 100%.
• Disconnect charger from the mains and disconnect the device.
• Connect the charging cable to the turned off phone and plug it in. perform this action several times until the notification that the smartphone is fully charged appears.
• Turn the device on and go to its settings, where you deactivate the “Sleep mode” option.
• Charge the smartphone to 100%.
• Now we leave the phone to discharge, constant backlight of the screen will accelerate the process.
• Activate the “Sleep mode” and charge the device again.

Your device will deliver the right amount of power once you do this.

The method recommended by Google specialists

On the forums of Google specialists shared their method of calibration (suitable for the most hardy users):

• Discharge the smartphone completely.
• Connect the charger to the device and charge it for at least 8 hours, not paying attention to the fact that it is reported to be fully charged.
• Disconnect power cord and turn off your mobile device.
• Connect charger to the switched off device again, keep it charged for an hour.
• Disconnect the smartphone from the charger and turn it on (some models can turn on by itself).
• Wait a few minutes, then turn off the device again and charge it for 1 hour.
• We disconnect the phone from the charger and turn it on.

Calibration via engineering menu

This method assumes to return to the initial settings, after which all data will be removed from the memory device, including statistics on battery use. If the smartphone has the information you need, you must first copy it to an external drive or to the cloud. Before performing a reset you need to do 5 full charge-discharge cycles.

To enter the menu you need to enter a certain number (unique for each model). If there are problems with access, you can use a software such as the MTK Engineering Menu or Mobileuncle MKT Tools. After entering the menu, you should go to “Restore and reset”, press “Reset settings”, and then confirm your intention.

Calibrating the battery on Android with root rights

This way to calibrate the battery with root rights is not popular, but still there are.

Let’s look at how the manual calibration with root through the Recovery menu:

• Putting the device into Recovery Mode. The methods differ depending on the device and the type of Recovery (stock or custom). Usually you need to press and hold the power and volume up buttons simultaneously to enter the mode, on devices with a physical home button you may need to press that too.
• In the menu under “Advanced” find the item “Wipe Battery Stats” and click, which allows you to clear the calibrations ever performed by the system or the user.
• Reboot the device and completely discharge it.
• Without turning the phone on, charge to 100%. The correct values will be detected by the controller.
