We set up an Android smartphone for the maximum operating time


The same smartphone can work differently for different people.Someone uses all the capabilities from and to, while the phone easily lives a day or even two, the other has a battery for dinner.In this material, we will try to make out all the moments affecting the work of the smartphone, we will see what to pay attention to and how to configure it.They often expect secret codes, instructions from me in the aspect of the smartphone settings, they do not believe that only an understanding of what you are doing and how and how.I’ll try to share this understanding with you so that you can consciously approach the question of how your smartphone works (and any other device).

As a reference point, he took his Galaxy S21 Ultra, it has several additional modes, use scenarios, but everything else coincides with most Android-smartphones, so this material will concern not only smartphones from Samsung.They just have the richest opportunities for additional settings.

You need to start dealing with the battery in the smartphone from one statement that is ignored by many, and in vain.The battery is consumable!Regardless of whether the replaced battery in the device or not is the consumable, and it changes its characteristics as you use it.Until humanity has Come up with an “eternal” battery, which on the first and last day of life would show the same characteristics.Over time, the battery capacity, the ability to work at negative temperatures changes.The first myth that has turned into a city legend is connected with this.

The myth about the battery on the Android Smartphone in a year

A year later, the battery of the Android Smartphone loses a noticeable part of the container, the smartphone works much worse.At the very beginning, my smartphone lived full time, now it is discharged by evening or in lunch.And I don’t need to tell me that this is not so, I see all this with my own eyes!

True or fiction?I am sure people sincerely say that they are observing on their devices.And there are several reasons for this, each of which affects the discharge of the smartphone, but the battery wear does not play any role, since in the first year the container under the most difficult operating conditions cannot decrease by more than 15%, on average it is 10% for allusers.

The first reason is in ourselves, as well as the availability of mobile Communications, in particular, mobile data transfer.More and more people watch films in high resolution, download them through a cellular network, transmit large files, constantly use cloud storage for their data.At the end of last year, we conducted a great study, studied how people use their smartphones, what they have in the first days of use, and what they put later.

It seems banal to someone that in the first month the number of programs on the smartphone for most users is minimal, then it begins to grow and reaches the peak by the fourth month.Something is changing, some programs are deleted, some put.But there is no constant and endless increase in the number of applications, this is the final process for the vast majority of users.

Many applications use access to the network, including mobile, occupy RAM and spend the energy of the phone.In most smartphones, unused applications are automatically translated into sleep mode.

This is a great idea that allows you not to configure everything with your hands, the smartphone yourself understands that you have not used the application for a long time, and therefore transfers it to sleep mode.Start the application, and after that for some time it continues to work as if it will be needed at any time.

Those who are trying to replace the standard interface, for example, use third -party shells, replaces the interface from the manufacturer with problems in the smartphone..The beauty of Android is that you can replace anything, but you will have to pay time for this.Thirder shells and interface design elements do not have optimization at the system level, as a result, they spend significantly more energy.And here you need to realize that you will pay for another interface, in this case it is the speed of work and the working time from one charging.

It is also worth remembering that the more applications you have, the higher the energy consumption (not tens of percent, but it rains a little).Therefore, my advice is simple: everything you do not need, you can safely delete.If necessary, install applications from the store, keep in memory hundreds of applications in reserve no sense.

Another important point is associated with data transfer, for example, in clouds.You can choose how your files are downloaded, programs can use both Wi-Fi and mobile data transfer.

Those who want to experience surprise can order details of the use of data on your SIM card for the last month (take the full month!), As well as for the same month last year.Many will surprise the differences, as the difference will be huge.You use a smartphone more - it discharges faster, everything is logical, right?The myth that the battery wears out so much that the working hours are changing and it is sharply reduced is just a city legend.The reason for this is that you use your device more actively, but simply do not pay attention to it (it is enough to change the permission in streaming services so that energy consumption increases dramatically, the device will transfer a larger data volume).

Unobvious Energy Events - Memory Maps, Assigned Memory

Many treat their smartphones responsibly, try to care for them to the best of their strengths and capabilities.I don’t know who laid the first brick in the myth that on Android smartphones you need to release RAM.In the "Settings" section, you can see how much the RAM is busy with the RAM, it is surprised that there is almost no free memory, and in manual mode to clear the memory.

It is definitely not worth doing this, since Android knows how to manage the RAM, there is no problem of busy memory.The architecture itself is such that in your memory those applications and services that you may need is needed, the system predicts your desires.By unloading them from memory, you actually force the device to do the same work twice, then they will need to be loaded and spent more energy on it.Regardless of whether there is an application in the application or not, it still spends the same amount of energy during operation.But the transfer of data is always spent on energy.Please do not need to climb with your hands that it works fine.I don't like the fact that all manufacturers have added utilities to clean RAM, as they are more harmful than useful.But they create a deceptive impression that you can take care of your smartphone.

On the other hand, in the S21 (more precisely, in Oneui 3.x) there is a Bixby scenario, this is automatic application optimization.At night, the device can close those applications that have not been used for a long time, but remain in RAM.There is no harmful in such a scenario, also a little useful.My experience shows that autoptimization is needed, since it gives up to 5-7% of the increase in operating time without closing applications..

Настраиваем Android-смартфон на максимальное время работы

A couple of words about SIM cards.Just as a battery is a consumable, over time, SIM cards contacts can oxidize, which does not affect the phone’s work, it sees the network, works great, but at the same time spends a little more energy on this.Use two SIM cards-then energy consumption increases by about 10-15% depending on the model.The reason is that the radio unit should now interview each network, since the radio part in most models is single.If you use ESIM, then there will be no difference with the physical SIM card, the energy consumption is about the same.

The use of memory cards also leads to energy consumption, it is impossible to avoid this.The installed microSD card on average reduces the work time of the smartphone from 3 to 6%, it all depends on the specific memory card and its characteristics.

I use flagships and choose models with a large volume of built -in memory (in the Galaxy S21 line, I Completely refused memory cards), I do not use memory cards.In Android smartphones it is possible to encrypt the contents of the memory card.If you do this, then it is worth remembering that working with a memory card will require additional energy consumption.

Now not the most obvious point, which, nevertheless, is the most relevant.The operating time depends directly on how much memory in your phone is free.The minimum volume that needs to be kept free is about 10% of the container, it is optimal to keep up to 20% of the space free, so that even “heavy” applications are not encountered with a slowdown in work.

Bad applications and what to do with them

It is no secret that there are various applications in the world, some are written well and work correctly, some are written crookedly and discharge the smartphone before our eyes.One of the applications that are harmful to the smartphone battery is Facebook, this social network wants to monitor its users, in fact, it can be said that this is a full-fledged spy program trying to collect any information about you and your device.I never put Facebook on my main smartphone, I try to use this social network through the browser window, and not a separate application.And this is not a fear of surveillance, the reason is that with the installed Facebook, the smartphone is discharged by 15-20%.Losing to the fifth part of the battery charge on one application does not make any sense.But it is possible that your work is connected with this social network and you cannot refuse it.

Among my applications, Skype is also harmful, but here the discharge goes during work, the battery melts before our eyes, since the software is far from optimization, the codecs used to burn the battery.

Built -in applications are always optimized for working with a device, for example, a video player spends a minimum of energy Compared to third -party programs.At the same time I like MX Player, I use this application.In the settings, you can choose a picture processing due to the "iron" device or software.In the second case, energy consumption is slightly higher, you also need to know about this.

In past years, the Chrome browser was another Energy Event, but today everything has changed, it behaves in a Completely different way.Please note that it is worth it to periodically close the tabs, the more open tabs, the more the browser takes up the place in memory, spends more energy on working with the application (I repent, I always have several dozen tabs, but I'm more convenient for me).

Setting up a smartphone, which is necessary and how to turn on

Modern Android is an advanced system in which you do not need to climb under the hood to configure everything for yourself.But there are several settings that are important for the system to optimize the battery consumption.

The first thing to pay attention to is the brightness of the screen.You can unscrew the brightness to the maximum (and many say that otherwise they paid the money, they will look at the full), but this is strange, since the maximum brightness is not always Comfortable.I have adaptive backlight, it adapts to my preferences (you can adjust brightness, the phone remembers your choice and next time offers the correct level).

The second point is the screen resolution, in the same Ultra is QHD and FullHD+ resolution, the second is by default, the less data is processed to output on the screen, the lower the energy consumption.On Ultra, the difference is 7-10%.

The screen frequency of 120 Hz is very pleasant, but it is also an increased energy consumption (the difference between 60 and 120 Hz is about 10%, that is, the hour of the screen, remember this).

In the battery settings you need to set adaptive mode, it helps optimize energy consumption.

Those who wish can play with GPS settings, but the system copes well with this (set access permission while using the application, this is enough).Constantly included NFC does not play a role, as well as Bluetooth, I have a watch and also used wireless headphones, I listen to music or podcasts.

I do not touch any other settings, since they are unnecessary, enough what I described here.And in this case, on the same S21 Ultra, you will easily get 10-12 hours of work, or even more.

How to charge a smartphone - fast or slow charging

There is no point in training the battery, you can charge your device as it is convenient for you.Fast charging has long removed the question that you need to charge the smartphone at night, and in the morning remove it from charging.My charging scenario suggests that I am charging the smartphone as needed, as a rule, this happens in the morning.If I go to the meeting, then I have about half an hour, during this time even a Completely discharged smartphone receives up to half a charge.In an hour it is charged whole (fast wired charging).In the car, it can be wireless charging.The myth that wireless charging wears out the battery strongly did not find confirmation in life, about the same battery degradation in the first year, there are no differences.

You can discharge a smartphone to zero only out of curiosity to see how it holds the load.But in ordinary life there is no need for this, charge the device as necessary.Do not charge a smartphone in very warm conditions, for example, by placing it on a battery or on a hot summer day on a car torpedo (I saw it, this is not a joke).

There is almost no difference between slow or fast charging, so close your eyes to all the differences, consider that everything is the same.

In the dry balance I want to say that everything with the configuration of the battery in the smartphone on Android is very simple and trite, there is no higher mathematics.Everyone will cope with this, but my main advice is this: do not go into additional settings, engineering menu, you still, most likely, will make it worse for yourself and the time of work.Modern Android Smartphone is frankly good in how he knows how to take care of himself.The main thing is not to interfere with him.Long work to your devices!
