The short battery life is one of the most frequent problems with every Android smartphone (and even iPhone), which can become big when the charge is almost exhausted and there is no way to recharge it, because you don't have a plug electricity and not even a portable battery. In this situation, which happens to everyone, it is important to know what to do, activate all the necessary options and also some tricks that can make the phone stay on as long as possible, at least in its most important function, that of calls.
Leaving aside to talk about the applications to make the cell phone battery last, here we see the settings to change when the charge is running out, going below 10%.
The following are not tricks to be used all at the same time, you can apply them differently depending on the case and depending on the need of the moment.

1) Check which applications are using the most energy.
Most Android phones have an integrated system in the settings to control phone applications that use multiple batteries.
In this way, you can close and end the one that consumes the most and obtain greater autonomy.
In the Phone settings, touch the battery option and if an external app is reported, which is not Android itself or Wifi or the screen, touch it and proceed to terminate it.
2) Lower the brightness
The screen brightness consumes energy, so keeping it as low as possible and turning off the auto brightness option will give you a definite benefit.
In almost every smartphone Samsung, Huawei and others, you can adjust the brightness of the notification bar and also from the Display Settings .
In the event that you are in a very bright environment, you will not be able to lower the brightness to the maximum, but you will have to choose the minimum that allows us to see the screen.
3) Turn off the cell phone signal
The cell phone signal consumes a lot of battery especially if you are in an area where the phone takes little.
So if you are not waiting for an important call, do not expect to receive SMS and do not use the internet data connection, you can turn off the cell phone signal to prevent the battery from running out soon.
To do this, go to Settings> SIM settings .
If the phone is dual SIM, turn off the signals to both.
If you don't find this option, put Airplane mode instead and then, if necessary, activate the wifi.
You can use airplane mode if you don't need internet and if you don't have to receive calls (maybe even keeping the GPS active if you use an offline GPS navigator).
4) Disable WiFi and geolocation
WiFi helps to drain the battery, although it consumes much less than the 3G or 4G internet connection.
If you don't need to be connected to the internet, you can turn off Wi-Fi from the notification bar.
Location services in Android require a lot of energy and should always be kept with a low power option, unless you use the GPS navigator.
When the battery is almost empty, it is better to disable the geolocation service entirely from the Android settings.
5) Use the energy saving function
Most new Android phones have a low energy operating mode, so that background services, automatic synchronization, GPS position and even processor performance are turned off.
The phone will seem slower, but it can still be used to do almost anything, even the internet connection.
On original Android, the energy saving option can be activated in Settings -> Battery, by pressing the button at the top right.
from here you can also choose to activate the energy saving automatically when the battery is only 5% or 15% charged.
On other smartphones there may be a proprietary function (like that of Samsung) to enter energy saving mode.
6) Stop the applications that are in the background and that we don't need to use
Many applications remain running in the background, even if they are not active.
Just think, for example, of Whatsapp or Facebook.
To conserve the remaining charge, you can do two things: disable the synchronization of everything or forcefully close the apps that are not needed.
To disable synchronization, you can use the option on the notification bar (if there is one) or the energy saving widget to put on the screen.
In original Android, you can go to Settings> Accounts and press the button in the upper right corner to stop automatic synchronization.
To force the closing of the apps in the background, instead you can do as in step 1 or go to Settings -> Apps, swipe left to switch to the tab of the running apps and touch those to be terminated.
On new versions of Android, this possibility is obtained by going to Settings> Memory, tapping on Memory used by the apps .
7) Use black background
This is a low impact trick, which only works on smartphones with an AMOLED type screen, which uses more energy to illuminate colored pixels.
In case the smartphone has a normal display, even if I'm not sure about this, it seems to save energy by using a single color background, so as to use a uniform backlight.
Keep in mind that when necessary, you do not have to turn the screen on and off frequently, because the standby mode is canceled by turning it on.
8) Hibernate Applications
If you are using Android Marshmallow or later, you should always keep Doze turned on, which prevents apps from consuming power when the phone is on standby.
With the Doze function, the phone can remain on in standby mode for up to 8 hours even if the battery is almost empty.
Hibernated applications do not use CPU, RAM, network and other resources.
The Android battery optimization function can also be had on every smartphone thanks to the Doze app.
