Devices that use the Android operating system in their work have long gained a reputation for rapidly consuming energy. Calibrating the Android battery can help with this. What is this process and how to do it?
Why calibrate your Android battery?
The fact is that the operating system remembers the modes of energy consumption. As a result, it may not be able to control the battery in an optimal way. Calibration fixes this problem. But if it does not help, then a new battery is needed (or is it it).
Options
For some actions, a superuser is required (obtaining root rights), for others it is not necessary. And although the main topic of the article is calibration in their absence, all options will be considered so that you can choose what you want.
How to make sure there is a problem?
Before you decide something, you need to make sure that there is a need. It may be that everything is all right with you. Check the operation of your device with two signs:
- Calibration of the battery on the "Android" is necessary if the device starts to turn off before a full discharge occurs. The screen can display 20, 50, or even 95 percent of the battery charge. But the smartphone or tablet, in spite of this, is still turned off.
- The operating time of a mobile device is quickly reduced. If immediately after the purchase the tablet discharged in five days, in a month - in four, and in two - in general in three - yes, this is a sure sign that the battery is not configured correctly. Therefore, calibration of the Android battery is required.
In both cases, actions must be carried out without delay.
What is called calibration?
If you look at the dictionaries, you can find out what is called the reduction of a device or device to an optimal state. Often this term is used in electrics when it is necessary to bring something to a specific standard. In our case, Android battery calibration is done to improve power consumption and maximize battery life.
Calibration feature in the absence of root rights
What does it mean? When there is no superuser, that is, there is no right to access system files and the "legitimate" ability to edit them, then you have to turn to technical features. When calibrating the battery, we will use them. But to obtain the desired result, you must strictly adhere to the instructions given.
The first way to calibrate without root privileges
Initially, we need to find out what capacity is in the battery (milliampere-hour). You can find this information by looking at the battery itself. If nothing is written on it, then look for the necessary data on the Internet (preferably in a review of a specific model). Why do we need this parameter? It shows how many milliamps a battery can produce in one hour. If this indicator increases, then the capacity drops. Now in the "Play Market" find an application that will show the battery charge in milliamps. You can search for Battery Monitor. As a recommendation, we draw attention to the CurrentWidget application. With the help of his control, you need to charge the battery to the standard that is provided by the manufacturer. Once the required number of milliamps is reached, you must turn off the mobile device and restart it. Such a reboot of the tablet or smartphone should make it clear what the current battery level is. If this does not help, do the same for five cycles. The battery capacity must surely gain the required maximum. After the fifth charge, 10-20 seconds after it was stopped (and the device is disconnected), you need to completely reset all the settings (roll them back to the factory settings). To do this, dial * # * # 7780 # * # * and press the call button. If this USSD request did not pass, then you need to look for information which analogue is used on your Android device.
The second way to calibrate without superuser
It has a lot to do with the previously considered option. Only here you do not need to install anything. So, in order to calibrate the Android battery without root privileges, follow these steps:
- Charge the battery so that 100% is displayed on the screen. After that, disconnect the charger. Turn off the smartphone itself (tablet). Then connect the charging cable to the device and wait until the battery is fully charged. It is advisable to focus on the LED indicator, but if it is not there, what is displayed on the screen.
- Turn on your device and deactivate the ability to turn off the screen on the machine. To do this, you usually need to work with the display settings (sleep mode). When the device starts to turn off, then again we charge the battery to an indicator of 100%.
- When the phone or tablet is fully charged, it will need to be able to work correctly with the battery. And the full discharge cycle for him will not be a problem now. But do not forget to reactivate the "sleep mode".
As you can see, calibrating the battery of an Android tablet or smartphone is not a problem even without root rights. Are there any other ways to debug the gadget? We’ll find out now.
The third method of calibration in the absence of root rights
Speaking about this method, we can draw an analogy with shamanistic actions - it is not clear how, but it works:
- Initially, you need to turn on your device and put it on charge. In this state, he must be kept at least eight hours.
- Then you need to disconnect the charger from your smartphone or tablet.
- Turn off the technique. After that, we continue to charge it for at least another hour.
- Disconnect the gadget from the power.
- Turn on the smartphone or tablet for two minutes.
- Turn off the device and in this state continue to charge it for at least another hour.
- Turn off the power and turn on the tablet or smartphone. Now you can use it as usual.
Calibration Tips Without Root Rights
Finally, I want to give some recommendations:
- If the battery is more than 5 years old, then it’s better to think about buying a new battery. But if you still decide to calibrate, and it will be without effect, then do not be surprised. It must be understood that calibration does not restore the device’s battery . Therefore, do not expect an increase in the energy reserve of the new battery, or resuscitation of an already practically "dead" power source.
- Take care of the original charges. Other devices can quickly drain the battery of your phone or tablet. This is due to the difference between the optimal and applied voltages, the current level, its frequency and some other factors.
- With prolonged use in places with poor communication (mountains or aircraft), the battery loses charge at an accelerated pace. The point is in physics - they need to catch a signal, and they look for it in the amplified mode.
We hope that these recommendations will help you to form an attitude towards the device and work well with it for a long time. Although if we talk about the opinions of knowledgeable people, they believe that the calibration of the Android battery (w3bsit3-dns.com, ciberforum and other specialized sites say so) should still be carried out with root rights.
Conclusion
Despite the apparent complexity of the problem that confronts us, it should be remembered that many tasks have simple solutions. So it is with mobile devices - to effectively solve the inconvenience it is not necessary to have modern technology or to understand complex programs to get the desired result.
