One of the many reasons many love android devices are their RAM, screen, and possessor capabilities. These reasons come with a requirement, a battery that can fully carry such action under heavy duress. Android devices are known for big batteries that range from 300mah to below 10000mah.
Because of the synchronization, it does not matter whether your battery 5000mah or 4000mah. An android device manufacturer using a 5000mah battery device instead of a 3000mah must have checked the workings of the device and relate it to the battery power.
Even though their batteries are nearly perfect, it is common for android users to complain about the battery in the form of many questions, and an example is why their android device shut off at 20%. An android battery is surrounded by many myths, such that you might notice that sometimes you can work with a 20% battery for like an hour while sometimes your phone reaches 20% and shutdown.
This action shows that there can be irregularity based on the linkage of the phone to the battery. Although an android battery is of known repute, they are otherwise known for this irregular problem, which makes users very annoyed.
It bothers many android users when their device suddenly shut down at 20%. The problem is only common to some android users, and for now, there is no general solution. Many reasons can lead to this problem, and they will be analyzed in this article.
The issue might be due to many things surrounding the battery. It might be in the form of the applications using much of the battery
This issue might be due to some things targeted at the hardware of the phone, for example, the battery calibration. For it to be the battery calibration, you must answer the question. Does your device still last the normal way it is before it dies? If it does, it can be said to an issue with the battery calibration.
Does your android device shut off at 20%? The solution depends on whether the cause is due to software issues or the battery itself. As of now, there is no general solution.
According to the online android communities, you can try some things, however, before trying a solution, be sure it to the battery or the software issue. The two categories of solutions are independent of each other, and their use depends on the device and the severity of the problem.
GET A NEW BATTERY
You should consider this first if your battery is very old. To do this, inspect the battery by looking for leaks or a bulge. If for any reason, your battery has a bulgy part, it means it has been losing part of its to power your device.
As your battery gets older, it becomes weaker. Even though it might be stronger at the moment, if you removed the battery after charging, it tends to go naught after some minutes or hours. Therefore, it might be best to charge your battery. While buying your battery, it is better to buy from your device manufacturer because buying cheap knock-off
CALIBRATE YOUR BATTERY
You should try this method if you are sure beyond a reasonable doubt that the problem is a software issue. The title can be confusing to some tech geeks because the battery is simply hardware and cannot be calibrated, but there is an inclusion of a printed circuit board that helps with the relation of the battery to the android firmware.
Calibrating the battery in this sense means that you are directing the operating system to correct information that shows the percentage the battery is at a point in time.
Depending on your familiarity with the android operating system, the process can be done in three ways, which are:
Calibrating without root access
This method is a reliable method for users that do not desire to void the warranty of their phones and other properties ascribed to rioting android phones. To calibrate your phone without root access, follow these steps
This method must not be continuously done because it can lead to the destruction of the battery
Calibrating without root access
Although I’m not that intrigued by the idea of deleting batterystats.bin file to calibrate and android devices, many people have said that it works.
Therefore, it might work for your phone. The process can be likened to the process mentioned above, just that the presence of root helps in making it more reliable
