Hello everybody. =) As promised, I spread the second part of the article on energy saving on Android. This time we will talk about the possibilities with root access.
ATTENTION! root-access is interference in the system partition, inept changes in which can lead to unpredictable consequences, therefore, for the actions described below, only you are responsible. Be sure to back up the firmware and data with copying it to somewhere. Even better, if you have a custom recovery, backup through which will help to "revitalize" the device even with an endless download / bootup (continuous reboot). And if this does not help, then ... ¯ \\ _ (ツ) _ / ¯ If you are not sure that you need a deep intervention in the system and are afraid of harming your device, then you can not read further.
You can even select and select multiple applications so that you can get rid of the lot at the same time. Power saving mode is a computer that reduces power consumption and saves battery capacity by disabling hardware devices that have been idle for quite some time. When it is on, your computer goes into sleep or standby mode when not in use. Turning off power saving options on your computer does not allow your computer to sleep during time-consuming tasks such as backing up a hard drive or converting a large media file to another format.
About what Root is, how to get it, the possible risks, the useful software - in this wonderful article on 4PDA
So, if you ruled your gadget, then you have additional options for saving power:
1. Remove or disable ("freeze") any applications;
Select "High Performance" in the Power Plan window. This will turn off automatic power saving mode. Select the System Preferences icon from the dock. Select the "Energy Saving" icon. Use the "Settings for" drop-down menu to select the power source you want to adjust, "power adapter" or "battery".
Uncheck the box next to "Put the hard drive into sleep mode, when possible". Close the window to save the settings. While mobile phones have been used to charge hours and days without recharging, the battery consumption of new smartphones and tablets is extremely large. The main reason - the display of smartphones and tablets, as well as a powerful processor.
2. Control the frequency of the processor;
3. Excluding programs from startup;
4. Search for programs that do not allow to "fall asleep" the device and / or overload the processor;
5. Modules for Xposed to save electricity.
You could add "Edit files in the system section manually," but this is even more dangerous than interacting with the system through specialized software, so I will not even mention it.
Which application sucks the most power?
Which application is "current" or hardware? Therefore, if you know if you can see somewhere, who can take the battery, please register in the comments. It now indicates who is responsible for what proportion of battery consumption.
Reducing battery consumption # 1: Reducing the brightness of the display
As you can see, the display is responsible for most of the battery consumption. Here you can save a lot of battery. As a hint, they say that it makes the screen automatically if you do not use it for a few seconds.From the first point and start. As I wrote in the first part, additional energy savings can be achieved with the removal / deactivation of programs. With Root access, you can remove / disable any program. BUT BE VERY CAREFUL: the removal and / or disabling of that-touch-it is impossible, can lead to negative consequences, down to "okrypirchivaniya." Applications that can be safely disposed of, you can specify on the subject forums. Or, alternatively, use Power Clean programs or application manager (ROOT) (links to the mentioned applications will be at the end of the post). In the first program, select the Application Manager, scroll the list to "Pre-Conf.", Where the applications are divided into those that can be safely disconnected and those that can not be touched. For the sake of fairness, disabling Play Store, Hangouts, standard mailer, which the application put on the list of "untouchables", did not do any harm to my phone. The second one generates a list of system applications, which is divided into three types: "You can delete", "Better leave" and "Delete unsafe".
As a recommendation, say, 30 seconds. If there is no monitoring during this time, the screen should go out. In addition, it is recommended to select the lowest brightness level of the screen. This again saves energy. However, this is only when the sun is low, because otherwise you would not know anything.
Reducing battery consumption # 3: stopping inactive applications
It can eat a lot of electricity. Or the mobile Internet completely disconnects, if he does not need it. The advantage, but also the lack of modern smartphones and tablets, is that applications remain in the standby mode, for example, when you return to the screen. Therefore, they are not completely finished, so you can go where you left off. But this application waiting mode caused battery consumption.
If the above is not scared, we will start with a less radical way. Perhaps the most famous program for shutdown ("freezing") is Titanium Backup. More precisely, this is only one of its many useful functions. To freeze the application, start the Titanium, click the Backups tab, where we find the desired application, tap on it and select "Frost!". But I, for example, disconnect applications through Lacky Patcher, another utility, but with a "bias" in the direction of patching and hacking applications. It is only necessary in the settings in the "Filter" section to tick off next to all the items, and then all applications will be displayed in the list. Well and further all is simple: on application\u003e Tools\u003e To disconnect the application (to freeze). The same author has a Lucky App Manager - Lucky Patcher without "illegal" functions.
Even if you rarely use your smartphone, the battery usually lasts just over a day. Video: Tips for a long battery life. Usually with this service there should not be a big problem. If, however, it consumes an excessive amount of electricity, it all quickly becomes annoying.
The fault of this often happens in the bow. If you also do not use the device, this process can also be displayed at the top of the list, without being a problem. It will be difficult if the battery loses a lot of energy in a short time. Sometimes this is due to the mentioned error, but more often to problematic applications and system settings.
I will list some more programs with the function of disconnecting applications: Link2SD, SD Maid, My Android Tools, System Cleanup.
Let's move on to removing system applications. Here I will say very briefly: Anything that can freeze applications, almost certainly knows how to remove and system. And also numerous file managers with application managers, individual application managers, all sorts of "combiners" ... The main thing is that they have access to root-privileges.
Thus, an error causes a high battery consumption
The beginning of the gallery. Mobile phone battery: find and turn off applications with battery power. Why does the service consume so much battery? This is due to the fact that if the error exists, it keeps the smartphone in sleep mode. Why this is so important, we describe in this article: - this is what is happening.
In this case, "Active" or "Save" is of particular importance. Longer than an eventful day, keep at least a battery of smartphones. On mobile phones with a much longer time without refueling in the outlet, users still have to wait for all the technical achievements. Batteries with a larger capacity than currently installed, really are. They will make everything brighter and more powerful the phones are thicker.
CPU frequency control
ATTENTION! Manually changing the CPU frequency can lead to hovering, unstable operation and, in theory, even damage to the device!
There are three main parameters that affect the power consumption of the processor, which can be changed: frequency, frequency control mode, voltage.
All modern devices can dynamically control the frequency of their processor depending on its load, thereby regulating its performance and power consumption. But this can not always happen correctly and most optimally, and the device will not have an economical energy consumption. In this case, in the absence of active applications, the screen is off, the processor frequency is reduced to the minimum value prescribed in the firmware core, as a rule it is 15-30% of the maximum frequency. In a properly optimized device, with an average daily load, most of the time the processor will operate at the minimum frequency. To estimate optimization of power consumption of the processor of the device it is possible having looked at the statistics of work of the processor on this or that frequency. To do this, open the Android System Info application, select the System Information tab and select the Processor item. If there you see that most of the time the processor is running at maximum frequency, then there is a problem with optimization. In this case, first of all you need to see the CPU load graphs in the monitoring programs, for example, SystemPanel. If the processor does not load any application, due to which its frequency rises, then the nominal mode of frequency control is not working correctly.
However, with the correct settings and small auxiliary applications, you can pick up a few more hours. Here are four tips on how the battery will last longer. The less often a smartphone needs to connect to the Internet to synchronize data, the longer the battery will last. Therefore, you must remove all unused applications from the phone or instruct them to synchronize only when you really use them.
With their help, use profiles can be presented. In the "General" section you select "background update". Now you can turn off the background update for all or only for certain applications. Some applications consume also unused much current. You can force applications to disable, disable or delete applications. In particular, the radio data can be quite limited. The only loss of comfort when the background update is off is usually only a slightly longer wait time at the beginning of the application.
To fix the situation, set SetCPU, with which you can not only set the operating frequency of the processor (or refine the range of operating frequencies), but also create frequency profiles that are activated by an event (application startup, charge reduction, screen shutdown, time), then there is an optimize the frequency control process for you. Also in the program you can manually select the operating modes of the processor. A detailed description of these parameters will turn a long-post into a very long post =), so it's more reasonable to limit oneself to references to programs where everything is described in some detail:
Meanwhile, many manufacturers offer energy saving modes. Then, for example, all phone background connections are limited during inactivity or the animation stops. Reducing the illumination of the display and restricting applications' access to the phone's location function also extends battery life.
If you do not need an Internet connection in transit, you can disable it. Continue reading on the next page. Batteries support the work of portable electronics. But energy storage is sometimes quite sensitive. With these five tips, the battery holders of smartphones, laptops or mobile loudspeakers last longer.
There are also analogues of Autostarts:
Startup Manager, Autorun Manager, AutoRun Manager (yes, developers sometimes do not bother with the names) and other programs that you can, if you want, be found on the network and the Play Store.
Search for "blank" and load processor programs
Some programs working in the background can wake up their phone in sleep mode (the so-called Wakelock) and not let it go into power saving mode, with the same "invisible" activity.
Lithium-ion batteries have no extreme values. They should not be empty or full. Especially, if the battery is constantly stored at 100% charge, it quickly grows old. Deep discharge, i.e. a battery condition with zero percent, significantly degrades memory.
You have to recharge from 40 to 85 percent. Too cold storage of energy there. Then they quickly lose their ability and can cause damage. They work best at room temperature. That's why a smartphone refers, for example, to a pocket of a jacket.
- Here is some money for your old mobile phone.
- What is the best insurance for one day?
- Five insurance companies that you do not need.
Before using any method, try to restart the phone first (especially with strong "invisible" activity or Running ~ 100%), this is sometimes enough.
Install the program Wakelock Detector and run it before going to bed. In the morning we watch how the phone "slept", what applications it "woke up". If an unfamiliar process enters the leaders, googled for what it answers and draw conclusions.
Lithium-ion batteries slowly lose their charge when not in use. And since they should not be completely unloaded, they are best stored at a load of 40 to 60 percent at room temperature. Over time, the battery capacity decreases. Therefore, the purchase of spare batteries is limited in stock. If he has been in the closet for many years, he will not get full performance in the event of an emergency.
This is the most important criterion in the smartphone: battery life. We explain to you the reasons and give valuable advice on reducing battery consumption. Below we explain to you when it comes to high battery consumption in the standby mode of mobile radio and what you can do about it. If you need more advice and advice, just write in the comments.
Install BetterBatteryStats, just run before bedtime, in the morning we look at the results. Detailed description .
Install the SystemPanel, go to "Menu-\u003e Settings", put a checkbox "Enable Monitoring", the other daws as desired. We leave the device for a while at rest, preferably overnight. After a while, go to Menu-\u003e Monitoring. Press the "History" button and see the graphs. You can set the output interval (if monitoring worked all night, it's more convenient to set "8 hours"). While in History, click on the button in the upper left corner of the "graph", select the Top applications there and get a list of applications and processes. We click on the most active processes and see information about the process, below we see the consumption history. We press the button "Compare", and from below we add the general charts. By looking at the graphs of all processes one at a time, in the end we find the culprits of not falling asleep ..
Causes of high battery consumption in mobile radio standby mode
With us, the battery consumption in the mobile radio mode since the last full charge was 58%. Clicking on the image, you will see a mobile signal. As you can see, the mobile signal has different colors. Colors mean the following. If the mobile signal is yellow or red, this increases the battery consumption, since more energy is required to receive the satellite. This can be seen in the form of waiting for a mobile phone. As you can see from the graphics, the battery decreases significantly when reception is weak, and with good reception the battery loses more slowly to charge.
Modules Xposed to save energy
If very briefly, then Xposed is a program for changing the settings of applications and firmware without the need for their decompilation, compilation and signature. The desired result is achieved with the help of the so-called. modules. And, as you may have guessed, some modules will help save battery power. Consider a few more: Power Nap, Amplify Battery Extender - Root, Greenify, Boot Manager,
But what are the causes of a bad mobile signal? You are in a new building: Signal strength is much lower due to concrete and co-author. You are in the car or on the train and pass through the woods or the like: The cover is also small, so the battery consumption is higher. In short: if the battery consumption is very high due to the waiting of the mobile radio, this is usually due to a weak mobile radio signal.
Type of network to save energy
If you are on a train or in a country, you can also change the type of network. Recommended for all fans - this is an application to reduce battery consumption. Since the application not only activates the power-saving functions, it also creates user profiles, so other functions are activated depending on the location and time to reduce battery consumption. The problem with powerful smartphones is a short battery life. Once the classic mobile phones lasted a week without recharging the battery, most smartphones are already dead in one day.
Power Nap is an analog of Stamina technology from Sony, but now available for Android devices version 4.1 and higher. The module stops background processes when the screen is off, but you can add to the list of exceptions those applications from which notifications are needed: social networks, instant messengers, calls and SMS, etc.
Amplify program nails the main system processes that consume battery power: NlpWakelock, NlpCollectorWakeLock, ALARM_WAKEUP_LOCATOR and ALARM_WAKE_ACTIVITY_DETECTION. This alone allows you to significantly increase the life time of the gadget between charges, and additional functions are available for the donation.
With intensive use, the recharge time is reduced to several hours. Since the smartphone is also small and convenient, energy reserves are limited. Manufacturers of smartphones should partially translate the square of the circle. Therefore, smartphone users should remember that the smartphone is a multimedia device with a short recharge time. If you want to manage the conservation of the sprint, you prefer to buy a small car.
Preparation: Information on battery usage and typical operating time
If you follow certain rules, you can significantly extend battery life. This article is based on. Current saving tips are listed according to their efficiency, so the first tips should lead to a significant improvement in battery life. Let's start with the manufacturer's specifications.
Xposed Media Scanner Optimizer will allow you to take control of the process of indexing media files and customize it to your liking. You will receive notifications about the start of the scanner and its completion, you can start and pause this process manually, set up directories and file types that will be indexed and much more.
Boot Manager does the same as Autostarts: removes programs and services from startup.
Greenify - module for hibernation (sleep) programs.
Here, basically everything. Of course, there are many more ways and programs that save battery life, but I did not set out to tell everyone about it. Cover all the features of devices, firmware, software in several posts is simply unrealistic. If you made a mistake, I forgot - do not hurt me painfully. =)
The shortcomings of smartphones running the Android operating system are traditionally referred to as low autonomy. This is due to the use in such display devices with a large
In contact with
diagonal and high-performance, and consequently, energy-intensive processors. While none of the Android-smartphones can not hold out for more than one day in offline mode, provided active use.Today, perhaps, only the developers do not want to recognize the presence of problems with the autonomy of Android-communicators. For example, the head of Google Larry Page said: "If the device based on Android is not able to work off-line and a day, then you need to look for the cause in the hardware."
Thus, if you follow the logic of Google, hardware flaws are found in almost all "Google phones". After all, many flagship phones with active use can not work for eight hours. Take, for example, HTC Desire. Like all modern Android devices, this model does not have a sufficient level of autonomy.
Let's do a little research and see how effective the numerous tips on what the Internet is today is. As practice shows, the vast majority of the so-called "secrets" do not carry any practical benefit. Let's try to figure out how truthful the most popular ones are?
Automatic brightness control
Myth: the setting in the screen settings of the function of automatic brightness control saves battery power.
How does automatic brightness control work? All modern Android phones are equipped with a light sensor that monitors the intensity of ambient light and gives the appropriate command to set the display brightness.
How does the automatic brightness setting affect the battery life?
Without automatic brightness adjustment: in this mode, the light sensor value does not affect the brightness of the display, which remains constant.
With automatic brightness adjustment: the ambient light sensor registers changes in the parameters of the ambient light and sends a signal to the processor, which, in turn, controls the brightness of the screen.
How does the battery behave? When the auto brightness function is on, the battery charge decreases quite rapidly. This is because the data from the light sensor is constantly transferred to the processor, which is forced to process them.
What to do to increase the autonomy of the communicator? Install the standard Power Control widget and bring it to the desktop. If you need to quickly change the brightness of the screen, you can click on the sun icon and select the desired level of the light. While using a smartphone outdoors, it is still more convenient to use automatic adjustment.
Myth is refuted!
A certain sequence of charging cycles can significantly increase the autonomy of the phone
Myth: in response to a complaint from one of the regular members of the XDA forum in HTC technical support concerning, the company's representatives offered to produce it, which supposedly should provide increased autonomy for the communicator.
- We charge the device for 8 hours in the usual way.
- Turn off the device completely and charge it for an hour.
- Turn on again, wait 2 minutes, turn off and charge another hour.
At the same time, it is claimed that the battery capacity should almost double, and many users even felt the difference.
Does it really work? No matter how meaningless it may sound, this method does work. This can be judged by the numerous reviews on the XDA forum, in which users claim that the procedure described above really increased the autonomy of their communicators.
Myth is confirmed with a high degree of probability!
Live wallpaper
Myth: use of the function "Live Wallpaper" (Live Wallpapers) very quickly leads to the discharge of the battery.
What is a live wallpaper?Live Wallpapers are wallpapers with the addition of animation / motion and give the smartphone's desktop an absolutely gorgeous look.
Does their use greatly affect the battery life? Yes! To draw animation wallpaper involves the resources of both the processor and the graphics core, which certainly affects the battery level.
How much is reflected? In most cases, live wallpaper "eat" no more than 2%. Live wallpapers really sink the battery, but many users will not stop it, because the visual effect of their application is worth it. However, it was noticed that some threads discharge the battery much more. You can check the effect of live wallpaper on the charge in the settings (Settings\u003e About\u003e Battery\u003e Battery Use). If this parameter for live wallpaper does not exceed 5%, you can not refuse to use them.
Kb5ZyuVXS4k
How to be? Enjoy the visual beauty of Live Wallpapers, knowing that iOS users are deprived of this feature.
Myth is refuted!
Automatic update
Myth: translating the function of automatic application update to manual mode helps to save battery power.
How it works? Programs (twitter-client, HTC Weather widget, all kinds of mail and RSS clients and others) constantly "climb" the Internet for information. In doing so, they use Wi-Fi, 3G or GPRS.
Does this affect the battery charge level? Of course, getting data via Wi-Fi / 3G negatively affects the battery charge. Moreover, if data transfer sessions occur frequently enough, the battery will be discharged extremely quickly.
How to be? Of course, it would be foolish to completely turn off the update, because then all the sense of using the smartphone is lost. Just need to make this process more efficient.
If you are an adherent of social networks and can not live without regular communication on Facebook, Twitter or receiving e-mail, you can, without disabling, set the frequency of downloading updates to a more economical mode. Optimum in this case will be a period of 4 to 8 hours. The most economical is the status update mode only when Twitter / Facebook-clients work.
Myth is confirmed!
Using special software to close programs
Myth: Closing (unloading) of unused applications can increase the battery life of the phone.
There are two different approaches to this issue. Some believe that removing unused applications can significantly increase the autonomy of the device, while other users, on the contrary, are of the opinion that this should not be done.
How to close programs? There is a special type of software called task killers. These are small utilities designed to unload from memory unnecessary processes to the user. They work similarly to the task manager in Windows, showing a list of running applications and offering to unload unnecessary ones.
The idea of the work of such programs is to release the busy RAM. This approach is relevant for the Windows environment, because we all know that with a large number of running applications, any Windows system will "slow down". In the case of Android, this statement is not entirely true.
Why in Android you can do without such programs? Answering this question, we will refer to the resource data of Geek For Me.
- If you need to release additional memory, the Android operating system itself can complete the execution of unused tasks.
- Android automatically completes the task if there are no calls to it for a long time.
- Most applications running in the background occupy a minimum of memory.
- Completion of some processes in general has a number of unexpected side effects, expressed in the absence of incoming text messages, missed notifications of events, etc.
- Many applications can finish their work by long pressing the "back" button.
How to be? Allow the operating system itself to work with tasks and processes. You should beware of programs such as Advanced Task Killer and use them only if the applications are not working properly. By the way, in Froyo (Android 2.2), the function of forced application termination is not provided at all.
