An urgent need to analyze the normal performance of the battery may arise among owners of new and “deserved” gadgets. No one is immune from trouble when the battery suddenly stops holding a charge and goes to zero after several hours of economical use. It is common for the device to shut down when there is 30-50% of unspent energy. In such situations, you should not rush to contact a workshop or service center. First, you need to use special applications that track consumption levels, the activity of energy-intensive tasks, and actual wear and tear.
Battery Life
Service utility with pre-installed profiles for saving and quickly restoring charge. Tests the speed of your network connection. Works directly with the battery controller to read reliable information. Compatible with Android (from version 4.1 and higher). Developed in variations for iPhone, iPad, iPod touch (from iOS 9.0 and watchOS 3.1).
A compact program for checking your phone battery, Battery Life, is distributed free of charge. Has built-in options for OS debugging. Calculates the percentage of charge remaining. Shows:
- operating voltage (voltage),
- magnitude of current (amperage);
- degree of heating (temperature).
Has the ability to clean RAM. Determines compatibility with chargers and extends battery life.
Important!
The battery calibration procedure allows you to combine the scales of real energy consumption and the accounting of this process by the operating system. This eliminates the problem of chronic undercharging and turning off the smartphone while the battery is still charged.
Calibration Methods
There are two main ways to calibrate the battery on Android:
- Manual method.
- Automatic method.
Let's look at each type in more detail.
Manual calibration method
First, let's look at the simplest type of calibration. All you need to implement it is Android itself and a charger.
- Charge the battery to 100%.
- Unplug the charger and turn off the phone.
- Connect the charging cable and plug it back in.
- Repeat step #3 until fully charged appears on the screen.
- Turn on your phone, open Settings and turn off Sleep Mode.
- Then charge the battery back to 100%.
- After the smartphone is charged, leave it to discharge with the display on.
- When the smartphone is discharged, charge it again.
This is where the “manual” calibration method ends. This should be enough for your smartphone to start using energy properly again. Don't forget to turn Sleep Mode back on.
Automatic calibration method
The automatic view involves installing a special application to calibrate the battery. As a rule, programs are divided into those that work with and without root rights.
Root (or Root) rights are superuser rights that allow you to log into the system as an administrator (developer). You can find out how to get root rights here.
The calibration process with and without Root rights is largely similar and has a few minor differences, so we will not describe each of them separately, but will provide general instructions:
- Connect the charger to your device.
- Launch the application.
- Once the phone is charged to 100%, leave the charger connected for another 1 hour.
- After an hour, open the application menu, click the “Calibrate” button and wait for the process to complete.
- Unplug the charger.
- Reboot your phone.
Attention! In some cases, a regular reboot may not be enough and you will need to do a full reset to factory settings!
This completes the calibration process; if you did everything correctly, then the memory of your battery has been reset.
Nova Battery Tester
An effective utility for determining the actual battery capacity for owners of Android devices. Provides three testing modes:
- fast (10-15 minutes);
- standard (30-60 minutes);
- full (60-90 minutes).
The smallest number of errors during the longest testing. To carry out the procedure correctly, a charge of at least 65-70% is required.
To check the health of the battery and phone, you need to download the technical specifications from the storage for comparison by using the “Get specifications” menu item. Then you should set the screen brightness to full, turn off Wi-Fi and GSM, and wait until the work is completed. The results obtained will indicate the battery capacity, the resource time of one division in seconds, the real and synthetic current strength.
What is battery capacity and what does it affect?
Any modern battery has a marking with information about the technical characteristics of the power source, including electrical capacity. To find it, let's see how this parameter is measured. The generally accepted off-system unit of measurement is Ah (milliampere per hour).
The battery capacity indicator is a numerical expression of how long the battery will last to power a load with a specified current consumption. It determines how long the device will work without additional recharging. The higher the number indicated on the case, the longer the gadget will work on one charge.
Battery HD Pro
The handy Battery HD Pro widget works as a real-time, multi-tasking battery level identifier. Shows in graphs and numbers the remaining energy in the context of operating modes:
- waiting, talking, video chat;
- reading, internet surfing, watching multimedia;
- photography, video recording, GPS navigation;
- flashlight illumination.
Equipped with battery test and calibration options. Can show current voltage and heating temperature. Available in versions for Android and iOS. Supplemented with a Russian-language interface.
How to Remove Unwanted Notifications from the Battery App
There's no denying the fact that battery apps can prove to be a vital tool in keeping your phone healthy and avoiding overheating issues altogether. But the unwanted notifications that come along with it can be a headache, especially if they are advertisements. In this case, turning off the notification option may be a good idea. Here are two ways to do this:
Method 1 : When you see a notification from the battery app, long press it and then turn it off. This will disable such notifications from the app. However, if you want to remove all types of notifications from the application, then prefer method 2.
Method 2: Open the Settings app. Go to Application > All Apps > Find the app > Tap on the app name > Notifications > Turn off notifications.
Ready!
AccuBattery
One of the best programs to check the health of the battery on an Android phone. Performs wear level analysis during each charge. Helps you choose the optimal charging and capacity recovery mode. Provides a recharging threshold of 80%, as the most gentle for the battery (manual reduction or increase of the limit is possible).
The AccuBattery utility produces a time forecast for mixed mode operation based on the user's regular habits. Prepares statistical reports on energy consumption (screen, standby, calls, applications). Calculates the remaining capacity and compares it with the nominal capacity to determine actual daily wear. week from the date of use.
Important!
Overloads from prolonged energy supply reduce the resource and capacity of the battery, so you need to give up the bad habit of charging your phone all night.
Checking battery wear using apps
The easiest and most accessible way to check the battery condition is to check using applications. This option does not require any financial costs and is completed fairly quickly. There are now a large number of applications available in the Play Market app store for checking the battery and assessing its level of wear.
Of course, applications cannot indicate the remaining capacity and battery life with 100% accuracy, but their estimates allow you to quickly navigate and get a rough idea of the situation. Below we'll look at a few apps you can use to check your battery.

AccuBattery is one of the most popular programs for determining the condition of the battery. The main difference between AccuBattery is that the application can assess the state of the battery based on statistics collected over a certain period of time. This allows you to get the most accurate value of the battery condition.
In order to find out the battery status using AccuBattery, you need to launch the application, open the “Charging” tab and scroll to the very bottom of the screen. A block with information about the designed and calculated battery capacity will be available here. But the application needs at least a few days to calculate the capacity, so initially this line will be empty.
You can also get information about the battery status on the “Health” tab. There are several graphs available here showing the wear and capacity of the phone's battery. But, as in the previous case, you will have to wait several days to receive this data.
Battery Alarm
The application has a friendly and simple interface. Provides free download and use without annoying advertising. Takes up little space and does not put additional load on the system. Created in variations for Android and iOS. Works in real time.
Main functionality:
- assessment of battery condition, temperature, voltage;

- operation of the device in sleep mode;
- autostart when you restart your smartphone or tablet;
- display notifications.
The Battery Alarm program for checking the mobile phone battery is equipped with a sound, vibration, flashing and graphic notification system when the battery is fully charged. The user can only choose the most convenient interaction option.
Programs that help check the health of your phone battery are an important element of equipment for modern gadgets. The presence of such software is especially important for owners of devices with non-removable batteries, allowing you to extend the battery life and avoid costly repairs. In this case, you need to select simple, small and proven utilities that really help, have high accuracy of information, and do not require unnecessary expenses.
When is calibration needed?
If you begin to notice that your device begins to discharge quickly or even turn off ahead of time, this means that the so-called “Memory Effect” has worked. You can retrain it using calibration.
The memory effect is a reversible loss of capacity caused by violation of the recommended charging regime, in particular, when recharging a battery that is not completely discharged.
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. The reason for this effect is the enlargement of the active substance in the battery and, as a consequence, a decrease in the active surface area of its working substance.
Setting up the battery through the engineering menu
Using the capabilities of the engineering menu is a radical method, when working with which you need to be careful. It involves resetting the smartphone to factory settings, so we advise you to first save all the data - photos, videos and music - to a memory card and remove it before starting so as not to lose anything.
- The first step is to discharge and charge the device exactly five times.
- Next, turn off the charged gadget and wait for at least half a minute.
- Afterwards, depending on the phone model, we go to the engineering menu. In most cases, this is done by simultaneously pressing the volume up and power off keys.
- The settings window lights up, in which we look for the wipe data/factory reset item, using the volume rocker as a switch.
- Select this item and wait within five minutes for the system to reset. When finished, the device will reboot itself and become available for use.
Such changes will probably fix all the problems, but if you don’t want to lose downloaded applications and other useful things, then there are other equally effective solutions.
Battery Doctor - Battery saver and battery cooler

Question answer
I had a Samsung Galaxy Nexus phone, a lot of videos and photos of my child from birth, and these photos were also uploaded to Google Photo.
Then something happened to the phone and it began to live its own life: I turn it on, it works for a maximum of a minute, then it turns off, turns on again for a minute or less and turns off again. And so on until I remove the battery (of course, during this time it is impossible to transfer files to another device).
The question is: is it possible to somehow transfer these files to another device? And why are they not in my account on another device. Currently the phone is Samsung Note 2.
Answer . The battery on your phone may be draining very quickly. We advise you to change it to a new one and check how your mobile device behaves. It is also possible that the Android system is eating up the battery. In this case, this article on battery optimization will help.
One more tip. If the files are on a memory card, you can remove it from your phone and transfer photos and videos via your computer to another device.
Root rights on Android
By purchasing a gadget, the user receives a lot of advantages of the world's most popular operating system, but not the opportunity to become its Administrator. It does not have access to the root folders of the OS and cannot change/delete files without some intervention in the system, which is called root rights (root is “root” in English), or superuser rights.
Such privileges open up enormous possibilities, including removing programs installed by the developer and configuring the system to suit your own needs. And this is used by advanced and not so advanced users, for whom the device “out of the box” does not have enough: processor performance, speaker volume or camera settings. The operation does not always end in complete success, and the consequences sometimes even require expensive repairs.
Checking for root on Android
You can verify whether root rights have been obtained by viewing files and folders on the device. The fact is that root today is acquired more often by software methods, and any application will leave signs of its presence in the file registry. If icons or SuperSU or Busybox Installer folders are found on the device, most likely there is root, or at least there was one.
But this verification option is not fast. Special programs allow you to quickly check a gadget for permissions: CPU-Z and their analogues, of which there are many freely available.
Ampere
While we do wish for a world where one Android device lasts a lifetime, the fact that your phone's battery is a piece of hardware makes it vulnerable to the test of time. If you're wondering if your mobile device's lithium-ion battery is dead, or you just want to know if your device is charging too much or not enough with your charger adapter and cable, the Ampere app is the right app for you.
Acting is simply a standalone battery monitoring app that helps you find metrics like Health , Temperature , Voltage , and Charging Speed . Most importantly, the Ampere app helps you recognize when your device is undercharged orange mAh ) and even overcharged (indicated in red ), helping you not only get optimal device charging time, but also maintain a stable battery environment.

How to prepare your phone battery for calibration?
To prepare the battery, the user will need to:
- remove the housing cover and check the integrity of the battery;
- check the integrity and correct operation of the port for the charger;
- copy data from the smartphone’s memory to an external storage device;
- start a complete discharge and charge of the battery without interfering with the process;
- Before starting calibration, charge the smartphone to the maximum value.
Important! After purchasing a new gadget, it is recommended to perform 5 full charge and discharge cycles in a row. This will help stabilize the Android system.
Close unused applications to save battery
Similar to turning off all wireless connections, make sure that applications that are not currently in use are unloaded from memory. This needs to be done because programs can still run silently in the background and consume the battery power of your smartphone/tablet. It’s not a sin to save on such amenities.
Alternatively, you can simply turn off background data for certain apps on your mobile device. To do this, follow these steps:
- On a Windows Phone device, go to Data Sense app > Set limits.
- On iPhone, go to Settings > General > Background App Refresh.
- On Android, go to Settings > Data Usage > Background Data Transfer.
Why does the battery drain quickly?
Naturally, first you will need to find out why the battery capacity/voltage decreased:
- this happened due to incorrect calibration;
- needs to be replaced due to wear.
First of all, let's check if this element is damaged before calibrating it. It’s much easier for owners of smartphones with removable batteries. You need to turn off the device, remove the back panel and carefully examine the battery. Check for leaks and swelling.
On devices with non-removable covers, it will be more difficult to find external problems, but this is also possible. For example, on a Samsung Galaxy, the battery is swollen and puts pressure on the body panel, so that a gap appears between it and the chassis. If you have a similar device, watch for these signs. Here's what it looks like on an iPhone:
One more thing - put the phone on the table, when it does not fit tightly to it, but is tilted at an angle or moves off, this is also a clear sign of a swollen battery.
After a complete check of the battery, if it is in normal working condition, you can proceed to further actions. But if there are doubts about the functionality of this part of the smartphone (or after calibration that did not give a positive result), you need to go to a service center and get an expert opinion. You can always change it and install the original or a proven analog from another manufacturer.
It’s definitely not worth saving in this matter, because this can only aggravate the situation and lead to problems with the operation of the entire device. It is also worth remembering that there are other reasons that lead to the malfunction of this component of the phone. For example, if it's not charging, your port may be broken, so rule this out immediately and learn more about what you can do about fast drain before calibrating.
With a recent firmware update of the device, fast discharge is already a common failure. You can solve this by clearing the cache memory on your mobile gadget (you will find how to do this on our website).
The easiest phone battery calibration - without root rights
In this case, the simplest solution is to use the Battery Calibration application. It is enough to download, install and run the program for the process to begin. When the program is turned on, the charge should reach 100 percent. After this, you will need to leave the phone with the charger connected and plugged in for at least 60 minutes. After this, the “Start calibration” command is activated in the application. When the calibration procedure is completed, the controller's memory will return to zero, and the application user will receive a notification about the completion of the operation. Finally, you need to disconnect the phone from the power supply and reboot the system.
When should you calibrate your battery?
This operation should be performed in the following cases:
- the smartphone turns off unexpectedly even if the battery is fully charged;
- the gadget works stably up to 20 or 15 percent, and then suddenly turns off;
- discharges to 5 or 1 percent, and then works for quite a long time;
- the phone begins to discharge faster - for example, after buying a smartphone, a 100 percent charge lasted for two days, then for one day, and so on.
Incorrect charge display is a problem with the operating system, not the battery itself. If the battery has been in use for a long time, swelling or leaks are visible on it, calibration will not help - you should contact a service center.
