Why does my Samsung Galaxy phone drain quickly?

Nothing is perfect in the world that surrounds us. And this statement has the most direct relation to the field of mobile technologies, and market leaders with enviable constancy step on the same rake, completely refusing to learn from their own mistakes. Therefore, the situation when a technically perfect flagship turns off from exhaustion in 3-4 hours has become a sad norm. Take for example the commercially successful Galaxy line - the flagship models of the South Korean corporation Samsung. The same S6 / S6 edge with peak hardware characteristics can “boast” of a more than modest 2550 battery (2600 mAh), which is critically small with such a powerful filling. What if your pet can't make it to the end of the working day? Is it possible to somehow "extend the life" of Galaxy smartphones from a single charge? Let's figure it out.

Disable unnecessary services

Built-in Android Features

The Android OS takes care of customers, but in a rather peculiar way. Therefore, in the startup of most smartphonesby default, there are many services, the usefulness of which for users is doubtful. So, what can be disabled without any fear?

bluetooth. With a range of 10-20 meters, there is no particular reason to keep it constantly on. Moreover, if necessary, you can turn on the “blue tooth” from the system panel in just a couple of taps.
WiFi. The same can be said about wireless technology. For some people, always-on Wi-Fi is necessary for work, but for everyone else, periodic on-demand sessions will suffice. That is, the “always on” scheme should give way to the “turned on - worked - turned off” rule.
Google services that require constant synchronization. First of all, it is email and the app store.

Wi-Fi, Bluetooth and background sync are some of the main energy consumers

Special instructions: Root access is desirable

This wonderful utility works in tandem with the systemBatteryStats API and allows you to find out which background processes are taking a big load on the Samsung Galaxy battery. The interface is intuitive, and numerous graphics for each application will quickly bring the problematic program to clean water. And if you activate advanced mode, you can easily manipulate system processes.

This program does the same as the Android OS. Just a lot more convenient.

Adjusting display settings

A stunning Super-AMOLED screen with a diagonal of 5.1 inches and a resolution of 2560x1440 (for the Samsung Galaxy S6) pixels is great, but not if you have to pay for such luxuries with autonomy. Unfortunately, in some models of smartphones included in the Galaxy line, automatic brightness adjustment does not always work correctly, giving out an overly bright picture. Therefore, you can count on 30–60 “extra” minutes if you lower this parameter to the minimum acceptable values for you.

Effective way

Setting up an energy saving scheme

Many owners do not get their hands on such a “little thing”, but in vain. After spending 20-30 minutes once, you can “stretch” the battery without any side effects. In the above figure, the maximum processor speed is limited ("CPU power saving"), a special display mode is enabled ("Screen power saving") and the system of improved haptic communication is deactivated ("Turn off haptic feedback"). As a result, your Galaxy will not turn into a long-liver, but you will be able to get a certain increase in battery autonomy.

Setting the power saving mode

We clean the RAM

Imagine the situation: you launched a 3-dimensional toy in the subway, and when you reached the desired station, turned off the screen and put your smartphone in your bag. Theoretically, background processes should not have any significant impact on autonomy, but in real life this is not entirely true. Therefore, make it a rule to remove unnecessary programs from RAM. This applies not only to games, but also to GPS mapping services, music players, and e-book readers.

Clean and reinstall system

With prolonged and active use of a smartphone, a large amount of digital garbage inevitably accumulates in the OS. In addition to slowing things down, this can reduce battery life. A good way to get rid of both problems is a full factory reset and flashing. How can I do that?

Option 1. We go to the menu "Settings" / "Accounts" / "Archiving and resetting". After that, first tap on the "Reset device" button, and then - "Delete everything".
Option 2. First, Samsung Galaxy needs to be turned off. Next, we simultaneously hold down the hardware buttons “Volume +”, the central one and the power button, and as soon as the branded splash screen appears, release them. In the menu that appears, select the “wipe data / factory reset” item (use the “Volume +” and “Volume -” buttons to navigate), and the power button to select. In the next window, find the line "Yes - delete all user data". When the process is completed, select the first item "reboot system now".

Before resetting the system, once again make sure that you understand the consequences of your actions.

Attention! Both options will destroy all your data, including your address book. You should also understand that the slightest mistake can lead to serious consequences, after which the smartphone will have to be carried to a service center. Be extremely careful!

Limiting the appetites of weather informers

This is a fashion trend of recent years. A colorful and very convenient weather forecast that informs the owner of the smartphone about what surprises the heavenly office has prepared. But you have to pay for all good things: constant background synchronization with the server negatively affects autonomy. Therefore, if you are not ready to give up the informer, at least increase the update time to the maximum.

Complete system reconfiguration

For all installed applications, excluding the mail client and messenger, uncheck the box "Show notifications".

Disable Notifications

In an active Samsung account, we refuse to receive marketing materials, a combination of data and the choice of contextual advertising.

Opting out of ads

Disabling additional services

Turn off geotagging in the camera settings.

It is quite possible to live without automatic implementation

We refuse to send a report in case of failure.

Dutifully submitting an error report is not a good idea when it comes to power saving

In the "Security" section, disable regular checks to identify potential dangers.

Security Settings

In the “Settings” section, set the “Auto-update applications” item to “Never” and uncheck the “Add icons”, “Availability of updates” and “Auto-update” blocks.

Final chord: disable updates

Attention! The above screenshots apply mostly to the S4 model, but are equally applied to other smartphones of the Galaxy family (S3, S5, S6 + mini versions). Minor cosmetic changes may cause menu items to be named and styled differently, but the general access scheme will remain the same.

If buying a reinforced battery or an external extra battery is not your plan, and the autonomy of the Samsung Galaxy leaves much to be desired, these tips will surely come in handy. So you can count on a certain increase in battery life, the only thing I would like to remind you is to be extremely careful and do not change those settings that you do not understand the meaning of.
