Google annually adds a lot of settings and functions to the Android operating system, many of which are hidden from the eyes of ordinary users. This was 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 more slowly or discharge much faster, therefore, right out of the box, all smartphones based on Google's OS 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 software optimization for hardware, the hidden setting in all Android smartphones significantly increases the time battery life from the battery, and now absolutely anyone can activate it, since it is definitely available in any custom firmware and in all models mobile devices.
All smartphones based on the operating Android systems have an incredibly large margin of power, which is simply redundant for solving simple everyday screens. It's like driving a car, sometimes pressing the gas to the floor, and then slowing down again. In the case of smartphones, it’s not gasoline that runs out faster, but the battery charge. In order to increase the battery life of a mobile device, you need to launch "Settings", and then go to the "Battery" section.
In the "Battery" section in the upper right corner, three vertically located dots should be visible, 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, processor performance will be reduced, which will allow up to 50% increase in battery life on a single battery charge. This feature is available in all smartphones and tablets running Android 5.0 Lollipop and higher.
To achieve an 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 to work normally.
It is worth choosing the most basic messengers, mail clients and other major programs that should receive notifications in real time and not with a delay. This program works in such a way that all processes that run in the background and consume battery power are automatically frozen. This does not harm them or the data stored in them in any way, and using this application allows you to significantly increase 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%.
The level of customization (tunability) even official firmware mobile devices is growing every day. However, there is no limit to perfection, there will always be some little things that can be realized standard means system is not possible. But it is precisely from such trifles that the overall impression of using the device is formed.
In the framework of the current article, we will talk about one of those settings that is not available in every firmware of Android OS devices, namely, we will consider, how to turn off dead battery sound on android.
Change or disable Android system sounds
Android system settings allow edit various sound and notification settings: Incoming call sound, incoming message sound, alarm sound, camera shutter sound on/off, and so on. But turning off the sound of some notifications is not possible in every version of the system and shell.
These are parameters such as changing or disabling volume keys sound, notification sound low charge batteries and some others.
It’s good if these options are present in the settings with the ability to at least turn them off, 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 that warns of a low battery, you will either have to "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 settings without using additional programs. Below we will consider how to disable " battery sound" , played when it is discharged.
Turn off the sound of a dead battery on Android
Before all manipulations with the system, we strongly recommend that you make a full system backup(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. Neither the author of the article, nor the site administration mirAdmin are not responsible for possible consequences
We will now consider the option completely turn off the sound of a dead battery on Android.
What we need for this:
- empty sound file in the format ogg(below we will 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 directories.
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 one we need, set the permissions and reboot the smartphone. For example, you can use a file that plays the pleasant sound of a water drop: LowBattery-drop
Mute Volume Keys on Android
Similarly, you can turn off or change many different sounds of the Android system. We only need to know in which directories the sound file we need is located:
/system/media/audio/alarms/ - a directory containing possible melodies for an alarm clock;
/system/media/audio/camera/- a directory containing possible sounds for a standard camera, as well as a file for silent operation of the camera;
/system/media/audio/notifications/ - directory containing options for alerts;
/system/media/audio/ringtones/ - a directory containing possible ringtones for installation (call);
/system/media/audio/ui/ - 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 silence sound file above, or with the silence sound in mp3: volume-soundless- so we can mute volume control sound Played when the device's side keys are pressed.
But it should be borne in mind that some firmware does not store the sound of the volume control in an 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.
Do you have problems with your laptop battery and need to keep a close eye on it? By default, Windows only displays low battery notifications when it drops to 10% and 5%.
How to set notifications for other battery levels in a windows 10 laptop (similar in other versions)?
If your battery is draining fast, it's worth editing your notifications to display an alert when the battery drops to 50% and 25%.
Then you will be able to react faster and better control the rate of battery depletion. How to do it?
Low battery notification settings
The appropriate setting can be found in your meal plan options. To change them, go to "Control Panel", then to "System and Security" -> "Power Options".
Meal plans will appear in the list. Click the "Scheme Settings..." link next to the active plan (we can change the settings later for each plan). In the new window, go to the "Change advanced..." section.
The Power Options window will appear with a list of settings in the drop-down menu. Next, go to the very bottom and expand the "Battery" section.
Then we expand the "Notification of low battery" field, and look that in both cases it is set to "Enable".
Then we deploy two fields: a low level and an almost complete discharge. In both of these options, you can change the default charge levels.
Windows systems can have different notification settings, but you can set it to low at 50% and near full discharge at 25%.
Now you're done - the system will give you a notification after exceeding the threshold charge level that you specified. Good luck.
On my Lenovo laptop Y410 I installed Windows7. I used to have Windows XP. In XP, I got a low test notification when my battery reaches 10% life. In I even set the low notification notification, but still it doesn't notify me when the battery reaches 10% life and when it reaches the critical level of 5% it automatically goes to sleep. It annoys me.
Can anyone tell me why he doesn't notify me when he reaches low testosterone? I use a balanced diet. Low test tone notification is enabled and battery level is 10%. The critical battery level is 5%.
UPDATE: During the internet search problem, I kept the laptop on battery and every minute I watched the battery level. Previously when I used Windows XP it lasted 3 hours with dim light. Now, in Windows 7, it lasts one hour and as some other user asked a question saying battery life suddenly drops from 26%-5% (question here) even my laptop right after I saw 26%, it went into sleep mode According to the action of the critical level. I admit that some things are similar to this user, such as my battery is a year old. But I don't understand why it started all of a sudden when I switched to Windows 7 from XP. This is a little doubtful for me. Should I accept the solution given in this question, or is there another thing I should try?

This is already the case, then it could be a problem with the battery. For example, one post in this question. To check, change notification percentage about low battery on the more e.g. 30%. Then watch, wait and learn.
Steps to change notification percentage:
- [Right Click] food icon
- Select power options
- Click Change settings power of the selected power profile
- Click Change Extra options nutrition
- Scroll to and select Battery across [+]
- Expand Low battery
- Change battery On 30% or more
- Click OK.
Here are some more reasons. There was a bug related to Vista. However, some issues are related to the BIOS. So try updating it. Another solution is to remove the battery and clean the contacts with a pencil eraser. One person said that when he or she changed the action Critical Battery on the " Shut down" from " Hibernate”, a low battery notification appeared.
EDIT: The notifications you can set are just battery [level, notification] and spare battery*[level]. Win7 missing critical battery notification [only level and action].
If, for example, you installed the battery with low level battery life by 6% and critical battery by 3% [lowest bypass accepted], you can set the spare battery to 4% to act as the last power gutter warning until Accumulator battery works without any additional warnings.
[* The battery backup level is not associated with any action other than the warning alert - "Critical Battery Warning. You are now in standby mode. Your battery is very low (4%), please connect immediately. No, your computer will automatically go into hibernation soon. "]
So, to sum up - your spare battery level should be HIGHER than the rest.
