Android began to quickly discharge in standby mode, what should I do for the main reasons?

The gradual discharge of the battery is an absolutely natural process that always occurs, even if the phone is not used.

As a rule, battery reserves are consumed by maintaining cellular communications, transferring data on a Wi-Fi network, and running applications in the background. But if your smartphone battery loses its charge literally before your eyes when the screen is off, this is a reason to wonder whether everything is normal with energy consumption. In this article we will tell you why your phone discharges too quickly in standby mode.

Android phone discharges quickly, what is the main reason?

Let's immediately note that the battery sometimes drains quite quickly just a few hours after you buy the smartphone. But, the most interesting thing is that some users say: - the battery discharges 30 minutes after purchasing the phone. There's not even anything to say here. But the reason for the disappearance of energy in different models can be completely different.

If your gadget is brand new, but it runs out of battery power quite quickly, the following reasons may be to blame:

1. The OS of your Android is not compatible with its components;
2. The smartphone battery has low energy capacity;
3. The gadget's CPU is not designed for gaming programs;
4. The gadget has a very large screen, which is incompatible with the chipset of this phone.

It is impossible to argue with such reasons. Of course, it is possible to flash the phone for another OS. But quite often this only makes the situation worse. Also, you can't do anything with the CPU. Because of this, when you start playing, the smartphone starts to heat up and the battery quickly runs out.

Let's give the name of powerful chipsets that are much more efficient than their counterparts - Huawei, Qualcomm, Samsung.

But when your phone battery initially functioned at a normal level, and then began to run out quite unexpectedly quickly - a few months or a year after purchase. So, the reasons for the rapid discharge are most likely completely different:

1. One of the installed programs takes up too much battery power;
2. There is a virus on the phone;
3. The subscriber turned the screen brightness to maximum;
4. The user turns on the GPS navigator quite often;
5. A person quite often reboots his gadget.

These factors of rapid loss of energy can be corrected. Therefore, now we will begin to analyze them in more detail.

The root of the problem

Trends in improving the appearance of smartphones are reduced to two goals - the screen diagonal is larger, the body width is smaller. At the same time, the processor becomes more powerful and the screen resolution is better. How can you fit a decent battery into the thinnest smartphone? That is why the figures stated by the manufacturer rarely correspond to reality. If you really want to become the owner of a stylish modern gadget, it is better not to consider models in the cheapest price segment.

The rate of battery discharge is affected not only by its capacity, but also by the specifics of the Android operating system. It is based on the Linux kernel, and users of this OS have already accepted that devices running Linux quickly run out of power. However, if a smartphone discharges too quickly, the owner himself may be to blame, without even knowing it. To fix the problem, you need to study your battery consumption - fortunately, Android provides all the necessary information.

Brightness Reduction

First, let's lower the brightness of the monitor's backlight. This can be done from the notifications menu.

So, let's go to “Settings”, to the “Screen” tab. In this window you should see the “Adaptive Adjustment” tab. The Chickbox above it needs to be turned off. Having done this, the OS will independently adjust the brightness, observing the illumination of the room (street). Quite often, this feature is not available in cheap phone models. Most often they do not have a light sensor.

Turn off bluetooth and NFC

In addition, wireless elements use battery energy with sufficient force. For example, bluetooth, NFC, 3G b 4G, LTE and Wi-Fi. Bluetooth and NFS can be turned off by going to the phone settings, in the “Wireless Network” tab. Tap on the “More” button and we will enter the necessary submenu. The user sees the Bluetooth control button immediately.

In the “More” submenu, the user can turn off NFC if the phone supports this function.

Energy saving chipset

The baseband processor, application processor, and GPU unit are the three main power consumers after all of the above.

1. 1. The baseband processor deals with the network (its work just intersects with the point about 4G/LTE communications).
2. 2. The application processor processes the software part, audio, video, touch screen.
3. 3. The Graphics Processing Unit (GPU) helps draw the user interface and is one of the reasons why smartphone games have become so smooth and fast.

The application processor is becoming increasingly important because applications are the main selling point of a smartphone.

Previously, there was only one microprocessor core per application processor. Now there can be two or more. The massive increase in the number of processor cores, oddly enough, helps reduce power consumption.

For example, ARM's big.LITTLE architecture uses a simple trick for energy efficiency.

It combines a small, power-efficient ARM Cortex-A7 and a fast ARM Cortex-A15 for power-intensive tasks.
The more powerful the processor cores and the more cores you use, the higher the maximum power. This way, the A15 switches off when its hefty power isn't needed, like when you're just talking on the phone or writing email. If you want to play a 3D game, the A15 will come into play because the A7 won't be able to handle it.

The smartphone uses this approach to use the most powerful core only when needed. The most power-efficient core does most of the non-essential work.

Disabling unnecessary navigation chips

Budget options are equipped with cheap GPS chips, which sometimes do not have the A-GPS power saving feature. When the user does not particularly need navigation on the phone, we also turn off this function. To do this, go to settings and select the “Location” command.

This window contains the “Mode” function.

You need to select the “By network coordinates” command. By placing a checkbox over this function, the phone will no longer accurately find where the phone is located. But the GPS chip will be turned off and the energy consumption from it will stop.

Why does the battery drain quickly on a smartphone?

The reasons for the rapid drop in phone charge can be of a varied nature - from software to hardware. Among all their diversity, we would highlight the following:

• Causes:
• Explanation:

Battery Type

Why does my battery drain unusually quickly? Perhaps it's a matter of poor choice of power source. When purchasing phones, battery characteristics play an important role.

Among them:

• Capacity (unit of measurement - mAh).
• Type (Ni-Cd, Ni-MH, Li-Ion, Li-Pol).
• Operating period.

A battery with less than 1600 mAh is unlikely to last the whole day without recharging while actively surfing the Internet, making calls, and playing games. The relatively comfortable time of using a smartphone starts at 2000 mAh. Rugged phones have batteries with a capacity of 3000 to 4000 mAh.

The type of battery also affects how long it can be used without charging. Nickel-cadmium representatives (Ni-Cd) have become history due to their fragility, low energy intensity, and unjustified production costs. Metal hydride batteries (Ni-MH), which were built into old, large, inexpensive phones, have a relatively long operating time, but are inferior to other types.

Modern smartphone batteries are made of lithium (Li-Ion, Li-Pol). Both representatives are similar in their characteristics: high mAh numbers, stable operation, no “memory effect” (gradual loss of nominal capacity). However, they are sensitive to ambient temperature and prolonged periods of discharging/charging.

The previous period of operation applies to used batteries. For example, on a modern Samsung smartphone, the battery normally lasts from 1 to 3 years (depending on the intensity of use and device model). The need to recharge a new phone more often is noticed after a year of use. You should not expect long-term operation if the smartphone battery has served the previous owner continuously for 4 years.

Lithium-ion batteries of smartphones are subject to the memory effect, as a result of which they begin to lose capacity over time. In such a situation, calibrating the battery on Android will help.

Defective or old battery

The battery gradually loses capacity over time, so the phone charges quickly and discharges quickly. Aging occurs faster if the battery:

• is being charged with an unsuitable charger;
• is operated at too high or low temperatures, cooling below 0 and heating above 45 degrees negatively affects the durability of the battery;
• was completely discharged;
• Overcharging also negatively affects the life of the battery.

Before replacing the battery, you need to make sure that it is the battery that is causing the gadget to discharge quickly.

The check begins with an inspection of the battery. If the battery has plaque or rust on the contacts or case, or if it is swollen, it must be replaced. You can determine the actual battery capacity using programs. For example, on Android you can install one of the programs: AccuBattery, Battery Life or Power Battery. There are also similar apps for iPhone: Battery Health, Battery Life Doctor or Coconut Battery.

Owners of phones and tablets running the Android operating system can also obtain information about the battery status by dialing *#*#4636#*#* and selecting the “Battery information” line in the window that appears.

If the difference between the actual and nominal capacity is too large, the battery must be replaced.

Background running of applications

Again, another common reason why a smartphone quickly discharges. Very often, users have a huge number of applications running in the background, each of which creates its own load. To view the list of running processes, follow these steps:

1. Go to “Settings” of your device and select “Battery and Performance”;
2. Next, click on “Battery Usage”;
3. You will see a complete list of running processes, as well as general load statistics for each of them;
4. To disable the selected process, click on a specific game or application, and click on the “Stop” tab.

Attention! If you have Android Oreo installed, then in this version you can allow or disable background work for each application. This is especially true for those programs that are not adapted for this version.

You can do it like this:

1. Go to “Settings”, then go to “Applications and notifications”;
2. Here, click on the “Application Information” tab;
3. You will see a complete list of all programs and games. Click on what you need and click on “Battery Saver”;
4. Here, almost at the very bottom, you will only need to disable the background operation option, as a result of which the program will not be able to automatically load data and consume battery power.

Extra tip! To quickly clear the list of programs running in the background, you can use specialized utilities. For example, Clean Master does an excellent job of this, allowing you to close all unused applications on your device in a few clicks.

Wi-Fi, mobile internet, Bluetooth and GPS

When the gadget is operating, a lot of energy is spent on Wi-Fi, 4G Internet, Bluetooth, even when they are not in use. For example, the Wi-Fi module will constantly search for wireless networks to find a familiar one and connect to it. The same applies to other wireless devices. Therefore, you need to turn off all unused modules.

Far from mobile operator towers, for example, outside the city or in the metro, it is recommended to switch the gadget to airplane mode.

Increased screen brightness

The display is one of the main energy consumers. If the backlight level is set too high, the Android battery will drain quickly. To prevent this from happening, just follow two simple rules:

1. Set the screen brightness to automatically adjust. The system itself will determine the illumination level depending on the external lighting. In addition to energy saving, this feature provides additional comfort to the user: there is no need to strain your eyesight trying to read information on a dark screen in direct sunlight, and vice versa, an overly bright display does not hurt your eyes in the dark. The only limitation: this feature is only available to smartphones with a built-in light level sensor.
2. Set up a quick sleep mode when you finish using the device. In this case, only the display turns off, all other functions are active, so it is advisable to set the option to turn off the screen no more than 30–60 seconds after the end of user activity.

You can perform the described manipulations in the “Screen” section of the device settings: in the “Brightness” menu, you need to check the “Auto” box (or “Auto-adjustment”, “Auto-adjustment” - depending on the version of the operating system). Here you can set a fixed light level if the smartphone is not equipped with a light sensor. The lower the brightness, the lower the energy consumption.

In the “Sleep Mode” menu, by moving the slider or selecting a specific value from the list, set the desired waiting time before turning off the screen.

Viruses on a smartphone

Malware does not always operate openly. Often, infection can only be judged by indirect factors, one of which is the accelerated depletion of the battery. You should also be wary if:

• the device spontaneously wakes up from sleep mode;
• Unfamiliar numbers appear in call and SMS lists, and sites you have not visited appear in your browser history;
• communication modules or sensors are activated independently;
• installed antivirus programs have stopped running, and an attempt to download a new security application is blocked by the system;
• a message appears indicating that an application has taken over the functions of a device administrator (without your consent);
• Network traffic increased sharply.

If such signs are detected, you must use the installed anti-virus software (if there is none, download and install it first). If malware blocks attempts to launch the security utility, you can try to return the phone to factory settings (in this case, all traces of user activity, including the introduced virus, will be destroyed), or contact a service center for servicing smartphones of your brand.

Auto-sync

Disabling auto-sync saves more than 20% energy.

Follow these steps:

1. Open “Settings”;
2. Uncheck the date and time synchronization columns;

3. Disable auto-update of programs;

4. 
   In the “Alerts” tab, uncheck the update notification boxes.

Using your phone in low and high temperatures

It is ideal to use a smartphone or tablet at temperatures not less than +5⁰C and not above +30⁰C. Otherwise, the battery capacity will decrease, since in extreme heat the battery overheats, and in cold weather the current supply slows down. In the second case, the smartphone may turn off completely. Systematic use of the gadget in such conditions reduces the battery capacity and accelerates battery wear.

More than one SIM card

Some modern phones are equipped with slots for two or more SIM cards, and the device constantly automatically switches between SIM cards and updates information.

You need to set the priority for SIM cards in the smartphone settings or simply turn off one SIM when not needed.

Software load on hardware

One of the main reasons why a phone takes a long time to charge and quickly discharges is the increased load on the processor, RAM and other components created by programs. On Android, many applications can run background processes that reside in memory and use up the CPU. If some of them do not allow the operating system kernel to “sleep”, the processor is constantly loaded, which is why it consumes a lot of energy.

High CPU load not only reduces battery life, but also significantly delays the charging process. This is due to the fact that constantly active tasks in the background consume so much power that the phone does not have time to replenish it from the network. This reason is easy to diagnose: just wait until the phone turns off and charge it without turning it on. If the battery capacity is refilled much faster when it is turned off, the problem lies in the software load. In addition, programs running in the background are the main reason why the phone heats up and discharges quickly. After all, the increased load on the CPU does not allow it to cool down.

Getting rid of excessive battery charge caused by programs is very simple: just go to the settings and perform a factory reset. Before this, you need to make a backup copy of all important data stored in the smartphone’s memory! Simply uninstalling all programs can also help, but not always. If there are a lot of “tails” and “garbage” left by applications, you cannot do without a general system reset.

System or hardware failure

Laptop and PC users may experience an issue where the computer does not turn off completely. The screen goes dark when the OS shuts down, but some devices remain active - the indicators light up, the cooler continues to rotate, etc.

A similar problem occurs on Android phones, but it is not so easy to notice, since the gadgets do not have a cooler, and the indicator only shows the charging process. If such a malfunction occurs, the phone essentially remains on all the time, and battery power is consumed.

The reasons for this problem include faulty programs, OS errors, viruses and hardware malfunctions (including connected devices - SIM cards, memory cards, etc.).

The only symptom that allows you to suspect that the gadget is not completely turned off is too high battery consumption, when it should be minimal. To check, you can remove the phone cover and use your fingers to check the processor temperature.

If the device is running after turning off, the processor remains warm. In this condition, the smartphone case can sometimes heat up, but it all depends on the design.

In such cases, the following steps should be followed:

• We remove applications that were installed before the error appeared.
• We carry out anti-virus scanning.
• Disconnect all connected devices.
• Reset the system to factory settings.
• We remove the battery (if it is removable), hold the power button pressed for 30 seconds, then replace the battery.
• We reflash the phone with known working firmware.

We check the smartphone by turning it off after each manipulation. If the problem cannot be solved, then the phone should be taken to a workshop for repair, since the problem will not go away on its own, and the battery will exhaust its life much faster than during normal operation.

Physical damage to the smartphone

Physical defects in a smartphone can also lead to accelerated battery drain. If the fall causes the contact between the battery and the motherboard to deteriorate, increased resistance occurs in this area. Part of the energy is spent on heating the contacts through which current flows; sometimes losses can be about 50%. In addition to the rapid loss of cherished interest, there is also a slowdown in the charging speed. After all, the current that the adapter supplies is also partially lost in the form of thermal radiation.

Small short circuits on the board, as well as failed sensors and other small components, can also become a place of increased resistance. For example, when moisture enters, the contacts oxidize and parasitic contact appears between adjacent tracks or components caused by oxide deposition. It is weak, which causes increased resistance at the point of contact and energy leakage. Because of this, the phone discharges quickly and charges slowly. In addition, the device can charge slowly even when it is turned off.

It is very difficult to diagnose phone damage at home. To do this, you need to contact a specialist who has diagnostic equipment and tools. He will find defects, eliminate faults, and replace damaged components. Oxidation and other deposits on the board are removed by washing the device in an ultrasonic bath with alcohol.

Disabling games and applications

To save battery power, it is advisable not to play games (or play much less often), since games consume battery power more than other applications. At the same time, some shareware applications take up charge even while in the background. You see evidence of this in the messages that constantly arrive on your phone.

As mentioned above, various reboots take a significant amount of battery power. Such recharges are often caused by unstable operation of various programs. We will also uninstall them.

Battery usage rules

Just a few years ago, when buying a new smartphone, sales consultants advised “rocking” the battery - completely discharging and charging it several times in a row.

Now this advice is absolutely useless, since new batteries such as Li-Pol and Li-Ion use other technologies that such “stress” only harms.

Below are tips for using your phone to help extend the life of your Android battery.

1. It is extremely undesirable to completely discharge the phone, as this leads to a reduction in its lifespan. This occurs due to chemical degradation.
2. You should charge the device as often as possible.
3. The best charger you can use is the original one. Even though most phones now have the same connectors, each charger has a slight difference in voltage.
4. Do not keep your phone charging in direct sunlight. Even such a minor factor will greatly affect the duration of the battery charge.

Reset

In addition, the Android OS on the phone could also be affected. In this case, it is advisable to return the factory settings. Don’t forget that when you roll back to them, you will delete all your information from your phone, including subscriber numbers.

Root rights also have an impact on autonomous functioning. If you remove them, it is quite possible that the phone will start functioning longer.

Also, it may very well be that the lion's share of energy is taken by the applications that you have installed on your phone. Some of these applications are so poorly optimized (quite possibly on purpose) that they consume a decent amount of electricity.

For example, these include Facebook and Facebook Messenger. This application has access to almost all the information that is available on the phone. Also, this program takes a lot of battery energy, which is why its charge runs out.

CPU

There are three main parameters that affect processor power consumption that can be changed: frequency, frequency control mode, voltage.

Frequency.

All modern devices can control the frequency of their processor, reducing it under light loads, thereby reducing power consumption. A properly optimized device should go into power saving mode when the screen turns off, reduce the processor frequency to 15-30% of the maximum value and remain at this frequency until the user wakes up again. Therefore, you can evaluate the optimization of device power consumption by looking at the statistics of processor operation at a particular frequency. To do this, open the Android System info application, select the System tab and the CPU item.

If the processor runs at maximum frequency most of the time, then there is a problem with optimization. To solve this, install the SetCPU application (root is required), with which you can not only set the operating frequency of the processor (or specify the range of operating frequencies), but also create frequency profiles that are activated by any event (launching an application, reducing the charge, turning off the screen , time), that is, optimize the frequency control process for yourself. For example, the frequency in operating mode can be set to no more than 1000–1200 MHz; for the event “screen is off” and “charge less than 15%”, limit the maximum frequency to half the operating frequency, and set the minimum frequency to minimum; set profiles for frequently launched applications, limiting their maximum operating frequency to the value at which the interface responsiveness is comfortable for you (for example, 800 MHz may be enough for games, and 500 MHz for watching movies and listening to music). This approach will help save up to 50% of the charge consumed by the processor.

Optimized processor

However, it should be understood that the lower the frequency, the less responsive the interface may become and the lower the overall operating speed. Processor frequency control modes. These modes (algorithms) determine how the processor frequency will change, within what limits and how quickly, depending on the load experienced by the processor, its duration, and other things. Frequency control modes and frequency change steps are built into the kernel, and their set may differ for different firmware. I will not give a description of these modes; if necessary, you can easily find them yourself.

Processor not optimized

I’ll just say that for multi-core devices it is preferable to use the hotplug mode (if you don’t have such a mode in the SetCPU list, use interactive, or ondemand, it is available by default on most cores), which disables unused processor cores during idle time and is the most effective in terms of productivity/efficiency.

Reducing processor voltage (undervolting).

This option for optimizing processor power consumption has already been discussed in the article How to save Android battery power, so we won’t dwell on it.

Studying the power consumption of applications

In previous versions of the Android OS, it was unclear how much energy a particular program consumed. But now, when we enter Settings, we will see the Battery tab. It shows quite accurately that applications with games take up the lion's share of energy.

Samsung phones have the ability to see the power consumption of any program more accurately. All data is contained in the window of various programs in the Application Manager. In this function you can see exactly what load a certain program creates on the CPU. In addition, there are other interesting data here.

About malware

I already mentioned above that malicious applications take up quite a lot of electricity. But, from the Google Play resource it is not as easy to download such a pest as it might seem. But on some other sites there is quite a lot of this malware. From here, you can block downloading programs to your gadget from other resources.

To do this, we will enter the settings submenu called “Security”. In this window, we move the slider to the right, using it above the “Unknown sources” command.

In addition, it is advisable to install anti-virus software on your phone.

Useless recommendations

• On the Internet you can often find advice to use applications to calibrate the battery, for example, Battery Calibration. In fact, it is absolutely useless. Some claim that it helped, but these are isolated cases, and most likely this was not even the reason.
• There is also a recommendation to use the Clean Master application to clean the device and optimize it. This makes no sense, since all these programs consume a lot of battery and load the device. They are suitable if you need to clear the device's memory, after which it is recommended to remove them.

How to save energy on Samsung phones?

Some gadgets from the manufacturer Samsung have a display created using Super AMOLED technology. This technology helps save energy. But, let's look at a couple more methods to help reduce iPhone battery consumption.

Important: - this method only applies to new Samsung phones, which are in the highest category in terms of price and quality.

Gadgets from South Korea are equipped with technologies that limit the functionality of programs that people rarely use. To activate this setting, do the following:

• Go to “Settings” of the iPhone;

• Go to the “Battery” tab;

• Scroll down the page. Here we find a tab that concerns optimizing the energy consumption of programs. Select the “Details” button;

• Let's enable this setting. So, if the user does not turn on some program within 3 days in a row, this application will be frozen. It will stop functioning. This setting is very useful for users who like to install various software and games.

In this "Battery" tab, you can enable the "Power Saver" and "Extreme Power Saver" commands. These settings are very helpful for gadgets that have a Super AMOLED monitor.

In the first method, the colors are changed to look similar, but a little darker, and the display brightness becomes lower. You can preferably transfer information using Wi-Fi and turn off the location of the iPhone using GPS.

The essence of the second method is to turn the gadget into something like a phone with buttons. The display turns black and minor settings disappear, except for the ability to make calls.

Similar settings are also found on some other phones from other manufacturers. But they function less productively. Hence, I would not recommend hoping for more efficient functionality.

With each new version of the Android OS, more and more opportunities for saving energy appear. Therefore, gadgets running Android 10.0 are fundamentally different from their older counterparts that have Android 4.2 installed.

PART 1. IRON

Wireless networks and GPS

Remember: if you want to save energy, turn off unnecessary consumers, things that you are not currently using. For example, Wi-Fi and Bluetooth wireless networks left turned on constantly scan the area and look for available connection points or devices for sparring; enabled “data transfer” (mobile Internet) allows numerous applications to constantly “break” the network to update their data and send requests, additionally loading the processor and emptying paid traffic or wallet; enabled geolocation (GPS, GLONASS, determination of coordinates via wireless networks) helps to constantly track your position, fulfilling requests from curious applications. All this can consume a significant part of the battery charge, so I “washed my hands, turned off the tap,” well, in the sense of pressing the button and turning off the consumer.

Mobile network

The level of mobile network reception has a strong impact on battery conservation. The weaker the level of the received signal (fewer bars of the antenna indicator on the screen), the more energy the device spends on strengthening and maintaining this signal. Therefore, in areas of poor signal reception (on a train, for example), it is better to turn on the “Airplane” mode, thereby turning off the device’s radio module. You can do the same in the evening, turning off the radio module at night.

The problem of choosing: 2G or 3G When considering the characteristics of any phone, you probably noticed that manufacturers always indicate that the battery life in 3G networks is less than in 2G networks. This is explained by the fact that 3G networks are multi-channel and provide higher quality and reliability of the connection (seamless transition from one station to another). Therefore, if you are not afraid of short-term signal losses and slightly worse call quality when leaving an underground passage (although this depends on many other factors), you can select “2G only” in the network mode settings (Settings → More → Mobile networks → Network type) » (GSM only) and save up to 20% on network connections.

In addition, if you are in an area of ​​poor 3G network reception, and the automatic “2G/3G” mode is selected on the device, the device will constantly try to connect to the 3G network, even if its signal is several times weaker than the 2G signal. Needless to say, such constant jumps require significant energy consumption, which can also be avoided.

However, when it comes to data transfer (internet connection), the situation is reversed. For more or less significant traffic, it is preferable to use 3G or Wi-Fi networks instead of 2G. At first glance, this seems like a controversial statement, but the devil is in the details: firstly, data transmission on a 2G network (using EDGE technology) requires 30% more energy than on a 3G network, and only 10% less than Wi-Fi. -Fi; secondly, the data transfer speed on the 3G network (HSPA) is up to 170 times higher than the speed on the 2G network (EDGE), not to mention Wi-Fi, where the difference will be 600 times. This means that the device will require less time to download this or that information, and therefore less energy.

A simple example: you want to download several songs with a total size of 30 MB. With EDGE it will take 30 MB * 8 / 0.08 Mbit/s / 60 = 50 minutes, with HSPA - 30 MB * 8 / 14 Mbit/s = 17 s, but with Wi-Fi - only 30 MB * 8 / 50 Mbit/s = 5 s. Now, multiplying the download time by the average consumption of a particular mode, we get: for EDGE - 300 mA * 50 min / 60 = 250 mA • h; for HSPA - 210 mA * 17 s / 60 / 60 = 1 mA • h; for Wi-Fi - 330 mA * 5 s / 60 /60 = 0.5 mA • h. Ultimately, everything will depend on the amount of data: the larger it is, the greater the savings will be when using a faster network.

Conclusion.

If you focus on voice calls and rarely access the Internet (for example, only updating the weather and reading the news), it is preferable to use the 2G mode; it will provide the greatest energy savings. If you frequently use the Internet with a large amount of traffic (viewing pages with pictures, working with email attachments, downloading files), it is preferable to use 3G mode. As a compromise solution, if necessary, you can change the 2G/3G network settings using the quick access panel or widgets.

We use third-party programs

Google Play has a decent number of programs that help, according to the manufacturer, to increase the battery life of the phone. Practice shows that these are simple applications for optimization. These programs uninstall applications that you recently launched from the RAM. Usually they increase the performance of the gadget, but do not save battery power.

Conclusion: - If your Android begins to discharge quickly in standby mode, you now know what to do and how you can save battery energy using system means. In addition, you can go to Google Play and select the appropriate utility for yourself. It is quite possible that it will be successful and will help to really reduce energy consumption. Good luck!

Screen

Previously, it was believed that the screen backlight was the main component that drained the smartphone battery . It turns out that the statistics in the power and battery settings section are quite accurate and “tell” the truth. The screen is somewhere in third place in terms of energy consumption.

Smartphone batteries drain faster than traditional phones because we use their displays more often.

The backlight for a regular LCD (LCD) screen consumes a significant amount of power. If you reduce the time before blocking (for example, 15 seconds), you will significantly extend the battery life of your smartphone.

Auto brightness can help reduce battery consumption, but on the condition that it does not constantly turn up to 100%, but rather reduces the backlight to a greater extent.

Not to mention the latest organic light-emitting diode (OLED) displays. Their ability to self-illuminate individual pixels saved us from the general illumination of the matrix. They are more effective in settings where the interface is predominantly black.
