On a newly purchased mobile device time battery life significantly higher than a few months later. The problem suggests a low-quality battery and the need to replace it. However, do not rush and spend money on purchasing a new component. In most cases You can resolve the issue by following the instructions below. Consider how to calibrate the battery on Android using a manual or software method.
Determining the "calibration" value of a battery
Calibration is understood as the adjustment of the operation of a certain component, as a result of which it is brought to an optimal state. In the case of a battery, calibration helps to set the correct value for its volume, to prevent premature power failure and rapid discharge.
Signs of the need for a procedure
Before proceeding with the recommendations below, you should make sure that the battery really needs to be calibrated. The main signs of the need for adjustment include:
- Spontaneous shutdown of a smartphone or tablet in the presence of a residual amount of charge. For example, the device is forcibly turned off when the indicator shows another 5% charge. In a normal situation, the device should continue to work even at a rate of 1%.
- Reduced battery life. If initially the smartphone could function without additional recharging, for example, 3 days, and then this period was reduced to one day, this is explicitly indicates the need to calibrate the Android battery.
- Inability to get 100% charge. The problem is rare, but its essence lies in the fact that during the replenishment of the battery capacity, it is not possible to reach the maximum indicator indicator.
note
If at least one of these signs was noticed on the mobile device, you should calibrate using one of the methods presented below.
Manual battery calibration Android
The method involves setting up using a certain sequence of actions for charging and discharging the battery without using software. The procedure requires only Charger that came with your phone or tablet. Instruction:
- Required in full charge the battery, then turn off charging and . Next, the smartphone is put on charge again, but in the off state. Immediately after connecting the charger, the phone screen will light up and display the current state of charge. You should again wait for the indicator to 100%.
- The next step requires turning on the machine and changing its settings. You must disable automatic sleep after a certain period of inactivity and set the brightness to the maximum level. This will help speed up the discharge. Other methods can be applied - include the film in high quality using a Wi-Fi channel. The main goal is to discharge the battery to a complete shutdown.
- The final step will be recharging to the maximum value. When the full capacity is filled, you can return the settings to their original position.
It is important to know
After performing these manipulations, calibration will occur and troubles with rapid energy consumption should stop.
Android battery calibration through apps
An alternative calibration option would be use of special programs. Consider the process on the example of two most popular apps this category.
Battery Calibration
The application is available for download in the Play Market and, according to the developers, it can be useful in the following cases:
- done ;
- produced ;
- installed custom firmware;
- the battery has been replaced;
- the charge level is incorrectly displayed on a numerical or graphical indicator.
The software is used for:
- battery calibration;
- obtaining detailed information about the battery: temperature, condition, manufacturing technology;
- determining the current and maximum allowable voltage level;
- sound notification about the end of the charging process.
You can calibrate the battery on Android using "Battery Calibration"You can do the following:
Will be useful
According to users, the application helped to significantly increase the battery life of mobile devices and eliminate rapid discharge.
The essence of this Android battery calibration program is to display the amount of charge. Hence, knowing the capacity of the battery, you can bring the indicator to the correct value. Before proceeding with the installation and use of the application, you need to look at the battery capacity. This is done in one of the following ways:
When necessary information received, you can run the application and proceed with the calibration. To complete the procedure, you must:
When a smartphone is new, its user does not care much, because the gadget brings a lot of positive emotions and does an excellent job with the tasks assigned to it. But everything is not eternal, and technology has such a property as aging and wear of parts and deterioration common work. Probably the very first thing that starts to annoy the user is accumulator battery phone. And in today's article we will look at several methods on how to improve its condition by calibrating.
What is and why battery calibration is needed
Each smartphone or tablet based on the Android or iOS platform has a special controller that is responsible for the limits of battery charge and discharge. With the period of use, 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 does a reset default settings and sets 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.
Android Battery Calibration
Everything is simple here, calibration in the Android platform is done using special utility or programs. We will look at two of the 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 your smartphone or tablet;
We are waiting for the device to charge up to 100%, then a beep will sound;
After a full charge, you still need to wait an hour;
Press the Battery Calibration button and wait for the end of the procedure;
Disconnect the device from the charger and reboot the gadget;
All 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 of the license agreement and follow the instructions:
Connect the charger with open window programs;
Click the Calibrate Now!
We are waiting for the completion of the process;
At the end of the procedure, turn off the device;
With Android turned off, we are waiting for the battery to be fully charged;
Turn off the charger and turn on Android.
All calibrations are complete.
Remember! With Android 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 iOS system, always different long term performance compared to Android. Therefore, users are much less likely to ask the question of calibration.
At the time of this writing, there were no special programs for Android, and the whole process boils down to standard methods increase service life: carry out a complete discharge and charge for at least 10 hours.
If you have any questions regarding calibration, we will be happy to answer them in the comments below the article.
Modern man cannot be imagined without mobile phone and tablet computer.
We use these devices more than once every day, and some almost never let go of their gadget. But the more a person uses his electronic equipment, the faster its battery is discharged.
Based on this, the question arises - is it possible to somehow extend the operation of the smartphone or personal computer? It is possible, and there is a solution to this problem - you just need to calibrate the battery of the gadget. When should this procedure be carried out?
- If new smartphone actively used for about 2-3 days and the amount of charge remained the same;
- If the phone's battery starts to run low quickly.
There are two ways to calibrate the battery - using a special program and "manually". So, if the battery of your android device is not enough for you all the time, let's proceed to calibration.
The first and easiest way to calibrate an android battery:
You will need to download from Play market special program to calibrate the battery "Battery Calibration" and set it to electronic device.
It is suitable for all types of equipment and is installed on both the phone and the tablet with operating system android. After installation, run the program and follow the information on the screen of your electronic device.
The battery itself will perform all the manipulations, and the calibration will be done and completed.
One caveat - to use the "Battery Calibration" program, you will need Root rights access. If you do not have them, it is recommended to use.
You can use the second method of calibrating the battery
You will need free time and a great desire to have a battery with long time active use. In this case, everything is done manually.
Let's start with the calibration:
- We charge the electronic device in the on state for 8 hours. Before that, it is recommended to completely discharge it so that the charge is 0%.
- Turn off your phone or tablet completely and charge it for another 2 hours when it is off.
- Unplug your device and turn it on for 2 minutes.
- Turn off your phone and let it charge for another 1 hour.
After these manipulations, an electronic device on android will delight its owners with a long battery charge.
This method of battery calibration is suitable for both a smartphone and a tablet, since both devices charge in exactly the same way. Battery calibration is recommended for all types of devices that for some reason do not charge to 100%.
There are such situations, and instead of going to the service and giving your device for flashing, try to handle it on your own first.
There will definitely be no harm from this manipulation, but the battery power will definitely increase, and your gadget will keep the charge much longer.
This video shows another way to tune the battery.
Engineer Dianne Hackborn from Google debunked the myth known to all advanced Android users, which has been roaming for many years in all instructions and collections of questions and answers on this operating system.
She authoritatively and categorically stated: cleaning the battery usage statistics, which is stored in the batterystats.bin file and which is recommended to be deleted with each flashing of the device, does not extend the battery life of your android tablet or phone.
This myth is based on something like this: If at some point you have not fully charged your Android tablet or phone, for example, only 90%, it will remember this battery level, assuming that the battery is fully charged, and in the future you will use your battery only 90%, which is 10% less than its actual capacity. And if you delete the batterystats.bin file, which stores information about the battery charge, for example from ClockWord Mod Recovery by recalibrating the battery in this way, your Android devices o will forget about battery damage up to 90% and start using its full capacity again.
As Diane Hackborn explains, in other words it sounds something like this:
"The file batterystats.bin, which is located in the data/system/ folder, is used to get information about the battery level and display information about it using an indicator on the notification bar of an Android device."
However, she says that this is not true at all. Because the data stored in this file is only used to collect information about which process and for how long uses the battery at the moment when it is not charging. This is the information that you can see in your device's settings menu, under the "Battery" section. This file is not used for anything else.
Thus, it becomes clear that information about the battery level android system it does not receive from this file and it cannot affect the battery life in any way.
Moreover, all data on battery usage statistics that is available in this file is completely cleared every time the device's battery is recharged. Based on this, it is not difficult to guess that this is equivalent to deleting this file before each recharging of your tablet or phone, which you do almost every day.
Everything seems to be clear. It is not clear why many who have used this method of calibrating the battery, by deleting this file manually or using ClockWord Mod Recovery, report that their device has become longer without recharging its battery. Placebo effect or what? After all, the well-known program for calibrating the battery of Android devices, Battery Calibration works precisely on this principle, and the Market is full of positive reviews about it.
Probably, many faced the fact that a laptop or smartphone suddenly began to discharge or turn off by itself, even if their batteries had not yet had time to “grow old” thoroughly. If your device starts to give such signals, there is a high probability that it needs battery calibration in order to restore full operation.
The concept of calibration and the essence of its necessity
All modern gadgets and laptop computers equipped with high-capacity and long-lasting batteries. These batteries, in turn, have a device inside called a controller. The controller controls the battery and all its options, its purpose is to read all the information about the charge-discharge of the battery of your device.
In some cases (for example, irregular charging of the phone in a hurry, frequent charging with via USB from computer) the controller goes haywire and starts to read battery information incorrectly . Then a quick shutdown of the phone or laptop begins to occur - not because the battery has exhausted its resource, but because controller is not working properly . For example, if the battery level is not yet critical (20%, 30% or more), the controller automatically turns off the battery and the device turns off.
To do this, you need to carry out such a simple procedure as calibrating the battery. It lies in the fact that all previous indicators of the controller are reset, and it returns to the correct state of its work . You can calibrate the battery of any device yourself.
Is calibration needed?
In order to finally determine whether your gadget needs to calibrate its battery, watch it carefully, and in a short time everything will become clear to you.
Signs that the controller is not working properly usually look like this:
- Carefully monitor the battery level of your device during current operation. If the charge, although small, is still in the battery, and the gadget suddenly turns off, then calibration is definitely necessary .
- The battery charge level is in the range of 20-30%, and the battery starts to lose its resource too quickly and “sits down”, after which the device also turns off .
- Follow the process of charging the battery. If charging occurs unevenly, "jerks", or with a long "freeze" - calibration is needed .
Battery calibration process
To calibrate the battery of your device, you will need a few simple steps:
- Discharge the device completely.
- Wait for it to turn itself off.
- Put in the off state to charge.
- Wait until the charger shows the 100% battery icon.
- Do not remove the device from charging - the controller does not accurately display the process.
- Continue to keep the gadget on charge for at least another two hours.
- Now reboot your device.
- Repeat the whole algorithm of actions two more times, remembering that it is necessary to discharge the battery to full zero, and charge it to full hundred percent
If you have enough patience and you do everything exactly, then the controller will restore its full operation.
How to extend the life of your battery
First of all, don't forget regularly calibrate the battery - in order to avoid the next failures in its work. Calibrate the battery every two to three months and this will help prevent the controller from "cycling" on incorrect readings.
Also do not abuse fast phone recharges using a usb device from a computer and - remember that frequent recharging can quickly bring down the controller again.
Besides, do not expose your gadget to direct sunlight th. Lithium-ion batteries do not like sudden changes in temperature and can quickly lose their capacity if they are overheated or overcooled.
If you learn how to calibrate yourself, your mobile device or a laptop will work properly and clearly for a long time, and the battery will work out its resource in the best and optimal way for it. The main thing is to follow all the recommendations exactly and monitor the condition of the battery.
