The level of customization (customization) even official firmware mobile devices are growing every day. However, there is no limit to perfection, there will always be some little things that can be realized by standard means system is not possible. But it is from such trifles that the general impression of using the device develops.
As part of the current article, we will talk about one of those settings, which is not available in every firmware of devices on Android OS, namely, we will consider how to turn off the sound of a dead battery on Android.
Change or turn off Android system sounds
Android system settings allow edit various sound and notification options: incoming call sound, incoming message sound, alarm sound, camera shutter sound on and off, and so on. But the mute of some notifications is possible not in every version of the system and shell.
These are parameters such as changing or disabling volume keys sound, notification sound low charge battery and some others.
It's good if these parameters are present in the settings with the ability to at least disable them, but often there is no such function at all. What can we say about the availability of changing such notifications to a different sound. To turn off or change the sound warning about the battery discharge, you will have to either "sew" custom firmware, or, most often, install it on the device specialized software, which, unfortunately, does not always work correctly.
But, in fact, it is quite possible to configure these parameters without using additional programs. Below we will consider how to disable " battery sound" , played when it is discharged.
Muting a dead battery on Android
Before all manipulations with the system, we strongly recommend that you make a full backup of the system(nandroid backup).
Besides:
All actions performed by the user with his device and the system installed in it are carried out solely under the responsibility of the user himself. Neither the author of the article, nor the site administration mirAdmin are not responsible for possible consequences
We will now consider the option completely mute a dead battery on Android.
What we need for this:
- empty sound file in the format ogg(below we present it for download), that is, a file, when played, no melody is played;
- root rights in the Android system (the so-called administrator rights or full access);
- file manager on Android with access to system catalogs.
If we do not need to turn off the notification sound, but change it to our own, then in the same way we replace the file with the desired one, set the permissions and reboot the smartphone. For example, you can use a file that plays a pleasant sound of a drop of water: LowBattery-drop
Muting volume keys on Android
Likewise, you can disable or change many different sounds of the Android system. You just need to know in which directories the sound file we need is located:
/ system / media / audio / alarms / - a directory containing possible ringtones for an alarm clock;
/ system / media / audio / camera /- a directory containing possible sounds for a standard camera, as well as a file for silent camera operation;
/ system / media / audio / notifications / - a catalog containing options for alert signals;
/ system / media / audio / ringtones / - a directory containing possible ringtone (ringtone) settings;
/ system / media / audio / ui / - a directory containing system sounds, notification sounds.
For example, on some smartphones in the catalog ui there is a file like Volume.ogg or even multiple files: Volume-1.ogg, Volume-2.ogg, Volume-3.ogg, Volume-4.ogg etc.
If we replace these files (or this file) with the above sound file with silence, or with the sound of silence in mp3: Volume-soundless- then in this way we can mute volume control sound that is played when the side keys of the device are pressed.
But it should be borne in mind that some firmwares store the volume control sound not in open form, but in a compiled file, in this case it will not be possible to turn off the sound by replacing the file through the file manager.
Android is indeed a great operating system, but it also has its drawbacks. Some of them are congenital and you only have to put up with them, others can be quite easily eliminated. In this article, we have collected some of the most common Android problems and tips for fixing them.
Longer battery life
This is still one of the biggest disadvantages of mobile gadgets. Manufacturers continue to release smartphones with a lifespan of less than one business day. It is clear that design features modern batteries and the ever-increasing needs of devices have gone into deep contradiction. However, there are ways to solve this problem.
- When buying a gadget, please contact intent attention to battery capacity... Yes, you may have to pay a little more for this pleasure, but the freedom from socket dependence is worth it. Take a look at Motorola's MAXX lineup, Samsung series Galaxy Note and other devices that can show an outstanding survival rate.
- Buy an extra battery... If you have no current plans to buy new phone then it is better to purchase an extra battery. It can be either just an additional battery or replacing the existing one with a more capacious one.
- Reduce application power consumption... If you observe that the battery runs out even when you are not using your phone, then it’s time to tackle the applications that are running in the background. For this, it is good to use the recently described by us or the advice from this one.
- Use airplane mode... If the battery indicator shows less than 10%, then there is no time for fine tuning. Just activate airplane mode and you will extend the life of the device by several hours. You can do this at night if you are not expecting important calls. Disconnecting all communications reduces energy consumption to near zero.
Get rid of junk software
Manufacturers and sellers install a huge amount of unnecessary commercial software for many device models. And that can turn into a real problem. The software imposed on you not only takes up space, but also eats up system resources, consumes battery, and simply interferes. Fortunately, there are ways to fix this.
- Disable them in system settings. Most of these programs have system status and cannot be removed so easily. If you do not want to root the device, then you can almost always go to the settings and disable the programs you do not need, as shown in the illustration above.
- Get root and remove trash... Obtaining superuser rights is not such a terrible procedure. You can use either article. After that, you can completely remove or just freeze the programs you have selected. There are a large number of special utilities The most popular of which are Titanium Backup and RootAppDelete.
Hide or eliminate branded skins
Many manufacturers use branded launchers on their devices, which, however, may not be very convenient or consume too much system resources... You can solve this problem as fine tuning the corresponding shell, and its complete replacement.
- Go back to stock Android as much as possible. If you want to solve the problem with "little blood", then you will have to select and replace the launcher, keyboard, dialer, calendar and so on with real ones. google apps... We described how to do this using Android 4.4 as an example in these articles (,). Pay attention also to third party applications, which are sometimes distinguished by even greater capabilities and low consumption of system resources. You can start, for example,.
- Flash third-party firmware... If you are leaning towards a more radical and complete solution, then you will have to reflash your gadget with one of the third-party firmware. Developments such as have long since come out of baby diapers and provide quite stable, convenient and safe operating systems.
Turn off annoying notifications
As a rule, almost all programs have a corresponding section in the settings. Just do not be lazy to look for the options responsible for what, when and how often the application will display in the notification bar. This, incidentally, can further reduce battery consumption.
There is also a more radical way. In Android 4.1 and higher, you can open the application page in the system settings and generally disable all notifications from it. Just uncheck the box Show notifications as shown in the picture above.
Set the correct orientation for each application
Some programs look great in portrait orientation, others in landscape orientation. To put this under control, use the Smart Rotator utility, which provides us with a single interface to control these parameters and allows you to choose which applications will use automatic rotation and which will always adhere to vertical or horizontal orientation. It is especially good to use this program on tablets.
The battery level is displayed as an image of the battery in the area Windows notifications... More accurate information about the charge level (as a percentage, where 100% is a fully charged battery) can be found in the tooltip that appears when you hover the mouse pointer over this icon. However, the user may not notice that the battery is almost completely discharged. Therefore, Windows has a low battery notification mode, as well as actions that will be automatically performed when the battery level is low and critically low.
- Open the Power Options dialog box. Let me remind you that you can open it from the Edit Plan Settings window.
- Expand the Battery group and then the Low battery notification subgroup.
- Make sure that the On link appears to the right of On battery under Low battery notification. If the Off link is displayed, click it and select On from the drop-down list that appears. Low battery notification mode is enabled.
By default, 10% of full charge is considered low. You can change this figure by expanding the Low battery level group and selecting the desired value. So, for example, you can set the low level to 50%, and the low battery notification will appear when the battery is discharged to 50%. The Critical battery level group sets the battery level to be critically low. By default, this level is 5%, as a discount when you invite a host to a wedding Moscow prices. With such a discharge, the laptop can only work for a few minutes.
To determine the action to take when the battery is low, expand the Low battery action group and select the appropriate action: do nothing, put the laptop into sleep mode, hibernate, or turn off the laptop. You can also define the action to take when the battery is critically low by expanding the Critical battery action group.
When choosing a low or critically low battery action, it is best to consider putting your laptop into hibernation mode. When entering hibernation mode, the content random access memory enrolls in HDD and recovers when the laptop is turned on. Thus, you will not lose data that you did not have time to save before the battery was discharged.
Google annually adds many settings and functions to the Android operating system, many of which are hidden from the eyes of ordinary users. This is done on purpose, but with good intentions. The American corporation believes that if an inexperienced owner of some inexpensive Android smartphone accidentally activates certain important settings, then his device may start to work slower or discharge much faster, therefore, right out of the box, all smartphones based on the OS from Google have only basic activated functionality, but this is very easy to fix.
Although every year all smartphones work longer on a single battery charge, largely due to better optimization of software for hardware, but the hidden setting in all Android smartphones significantly increases the time autonomous work from the battery, and now absolutely anyone can activate it, since it is definitely available in any custom firmware and in all models of mobile devices.
All smartphones based on operating system Android has an incredibly large headroom that is simply overkill for simple everyday screens. It's like driving a car, sometimes pushing the gas into the floor and then slowing down again. In the case of smartphones, it is not gasoline that goes away faster, but the charge battery... In order to increase the battery life mobile device you need to launch the "Settings", then go to the "Battery" section.
In the "Battery" section in the upper right corner, you should see three vertically located dots, which you need to click on. In the menu that appears, you will need to select "Power saving mode", and then activate it. As a result, the processor performance will be reduced, which will increase the battery life by up to 50% on a single battery charge. This feature is available in all smartphones and tablets running Android 5.0 Lollipop and above.
To achieve even greater effect, the editors of the site recommend installing the Doze-energy-saving application, which significantly increases the battery life of all Android smartphones, since a lot of charging is “eaten up” by processes running in the background that the user does not even see. After installing it, in the list you need to select only those programs and services that should continue normal operation.
It is worth choosing the most basic messengers, mail clients and other major programs that should receive notifications in real time, not delayed. This program works in such a way that all processes that run in the background and take up battery power are automatically frozen. It does not harm them or the data stored in them, and using this application can significantly increase the battery life up to 40% of the standard. This is especially noticeable at night, when without this program the smartphone battery will be discharged by 10-12%, and with it only by 5-6%.
