Save Android battery, 16 moves

Your phone runs out of battery fast, so stay with us and read the tutorial on how to save Android battery in 16 steps. Sure, we call our Android devices "phones," but the modern smartphone is so wildly different than the one on your grandmother's kitchen wall, it would probably be more accurate to call them personal computers if the name wasn't already there.

How to save Android battery

All the processing power and computing capabilities our phones offer are increasingly impressive, but they come at a cost. We expect more and more from our devices with each passing year, but developments in battery longevity have not kept up with other technological advances.

Maybe that's why one of the most common questions we hear is: "How do you save Android battery?" Are you ready then let's read about how to save your smartphone's Android battery.

1. Turn off the things you aren't really using

When you leave your house, do you leave all the lights on, turn the air conditioning to full blast, and leave the TV blaring? Obviously not! Electricity costs money, and the basic economy means that most people have the good sense to turn off appliances and lights when they are not in use.

If you really want to save Android battery, the same principle applies, but instead of paying your irresponsibility with an expensive bill at the end of the month, you pay with a dead battery by 17pm. Let's take a look at some of the lights you may have left on.


If you want to save energy, you should always turn off Wi-Fi, Bluetooth and Location (GPS) when they are not actively used. If you want to be really aggressive with battery saver, you might as well turn on Airplane Mode when you know you don't need the phone at all.

Many users abandon these activated features all day. Enabling Airplane Mode will allow you to save Android battery. Airplane mode isn't just for when you're in the air, however.

Activating airplane mode or deactivating mobile data in favor of an available Wi-Fi network can make a difference in terms of consumption. If you have the choice between using the Wi-Fi signal or the cellular signal, always choose Wi-Fi, all others being equal. Wi-Fi drains much less battery than cellular service.

Turn off vibrations

Vibration is wonderful if you are in a situation where you would normally not be able to hear your cell phone, for example when you are traveling. For many people, the subtlety of vibrant notifications is indispensable in the workplace.

However, the vibrations of the smartphone are not evoked by magical resonant crystals. To produce the effect, your device has to spin a small motor that vibrates every time, which can be really draining for the battery. This also applies to haptic feedback, which is a slight whirring of the phone that is played when you tap keys on the on-screen keyboard. If you want to maximize your phone's battery life, you need to minimize phone vibrations.

2. Do you close apps when you don't need them?

For a long time, app-kill apps have been all the rage. Frustrated by the slow user experience, Android users of yesteryear started using all kinds of task managers to weed out apps they thought were hogging resources.

The problem is, these killer apps weren't needed before they even became popular. Android has gotten really good at managing its memory and most apps you close this way will come back to life.

In the modern age of Android maturity, there's no reason to have an app installed that closes apps left open in the background. Sometimes it's possible for apps to go rogue and start using up resources, causing you to drain more battery. If you use apps to close background applications, know that you are consuming more battery.

3. Battery saver application

If the process of managing your connectivity services day after day gives you a headache, then start working smart. What you are holding is one smartphone, after all. We will address them in increasing order of difficulty and involvement. In the school of automation, we have the three best Android battery saver apps.


IFTTT's goal is to put the Internet to work for you and save your Android phone's battery. The letters stand for “If This, Then That”. Once you subscribe to their service on their website and download the “IF” Android app, you can have your phone do a variety of things without your active intervention.

For example, you could activate the “Location” channel on your phone. This will allow IFTTT to respond to the location of the smartphone. So you might say to IFTTT, "Okay, if I leave the house, turn off the Wi-Fi." And then, in the same way, "If I get home, turn on Wi-Fi."

With a little creativity and foresight, you can quickly turn your phone into a fully automated machine that can handle your smartphone. Once you fiddle with it for a while, you'll start finding all sorts of things to automate, even your phone's battery life.

  • Download IFTTT


For the more technically inclined, Tasker is a battery saver app that gives users total control of their device. The level of precision and customization this service provides is frankly unmatched, but it can be a little daunting for new users.

Tasker allows you to create a variety of different contexts that change how the device works. For example, you can configure your phone to vibrate while you are in the office, but turn off vibrations and turn on Wi-Fi when you get home. The possibilities are endless and if your phone is rooted, you'll have even more options at your fingertips.

  • Scarica Tasker


Now, I said we would go through these apps in increasing levels of difficulty. However, the beauty of Greenify is that it's actually not difficult to use at all. The app allows you to "hibernate" annoying apps that work in the background for the consumption of resources, which in effect blocks them by force.

Unfortunately, to take full advantage of Greenify's automatic hibernation features, you need to have root access to your device. If the idea of ​​rooting your device is daunting for you, or if you don't even know what I'm talking about right now, then it's probably a good idea to use IFTTT or Tasker or know if it's worth rooting in 2022. .

If you've already rooted your device, I'm sure I don't need to explain how to use Greenify. Download it from the Google Play Store and take a tour.

4. How to optimize Android, use the internet intelligently

Mobile traffic accounts for an incredible amount of internet usage around the world. In fact, in our tests we usually find that it can drain more battery than continuous video playback! Try to spend less time looking for cat photos and you will find that your battery will last much longer.

As I briefly said above to optimize Android battery, you should always choose Wi-Fi to browse. Although it's always best to disable Wi-Fi when you're not using it. Your phone is constantly looking for open connections while Wi-Fi is on, and that unsuccessful search can wreak havoc on battery life.

5. How to save battery by reducing notifications

You don't have to allow your apps to automatically sync all their data. Choosing to do this manually or restrict autosync for apps that really need it can seriously reduce energy use.

6. Leave automatic synchronization

Auto Sync uses background processes that can affect both mobile data usage and battery life. To turn it off, go to Settings> Accounts. Tap the three vertical dots in the top right corner and deselect Automatic data synchronization. You can also manually choose which apps to sync and how often.

7. Use ad-free apps

Not only are ads annoying, but getting vibrant and engaging content to open on your device takes energy. Using apps that don't use ads, or buying premium versions of apps that don't have ads, can drastically change your battery level. If you use an app frequently and drain your phone's battery on a daily basis, consider upgrading or looking for an ad-free alternative.

8. Optimize battery by adjusting the display

Here we are. The MacDaddy of all battery drain: your display.

Go up Settings> Battery. You should see a list of apps that use up battery in order from the hungriest to the one that consumes very little. Which is the first? Chances are extremely good that it is Display and also by a large margin. Let's see if we can't make the display consume less battery.

Adjust the brightness

Well, it's kind of a no-brain, isn't it? Full brightness might be needed to see those texts in full daylight, but why are you still doing that setup after dark? Configure using adaptive brightness or auto brightness depending on the version of Android you are running.

Use the Adaptive Brightness features

If you like to see the screen in direct sunlight, but also have brightness under control, you can choose to leave Adaptive Brightness on. With this feature the phone will read the ambient light and intelligently choose the right brightness, ensuring a balance between a good viewing experience and battery optimization.

Some phones may have the app Settings arranged differently, but if you open it and go to the section Display, the option should be there (if available for your phone). It may also be called "Auto Brightness" or something like that.

Reduce the automatic blocking time

Since your screen is your battery's biggest enemy, keeping it off as much as possible is better. Go up Settings> View and changes the duration of the sonno so that it is as short as possible. 15 seconds is a good amount of time.

9. Optimize wallpapers and themes

Beauty costs and can also affect how long the device can stay alive on a single charge.

Ditch live wallpapers

Yes, that giant spiral galaxy slowly spinning in bright tranquility looks fantastic on our displays, but in everyday life these beautiful wallpapers take on processing power to come to life. Ditch them and go for something lighter.

Save Android battery by changing colors

And what is a wallpaper when you want to increase battery life? This actually depends on the type of display you have!

There are essentially two types of displays currently on the smartphone market. AMOLED and LCD. AMOLED works by illuminating individual pixels to create images. The LCD works with a backlight superimposed on a screen that dims and displays the backlight to create the pixels that make up the images.

This leads us to a counter-intuitive conclusion. If you have an AMOLED display, using a black background is more energy efficient because the display doesn't have to activate those pixels. They just rest. However, if you have an LCD display, the most energy efficient option is a white background because the screen doesn't have to work to create the pixels. Strange but true.

It should be noted, however, that the benefit of having a white background on an LCD is not as significant as the benefit of having a black background on an AMOLED display.

10. Restrict location services and background data

You can also save Android battery by turning off Location Services (usually in Settings> Location Services). You may want to prevent apps from using your location information. You will most likely want to disable the Location and Google Search option (or the Wi-Fi and Mobile Network Location option on some phones) to prevent your device from using Wi-Fi and / or mobile networks to triangulate your precise location and send the data to Google's servers. The process, needless to say, takes energy.

11. Delete android battery saver application that betray you

Some apps make intensive use of resources, either by nature (as in the case of games) or by incompetence or negligence of the developers (as in the case of poorly written apps).

You need to be vigilant about how your various apps consume battery power. A quick trip to Settings> Battery (or, on some devices, Settings> Power> Battery use ) usually reveals which app or service is consuming a lot of battery power.

Identify apps that are constantly draining your CPU and battery life. Poorly coded apps that connect to the internet even when they should be uninstalled, as well as apps that unnecessarily use a huge amount of CPU resources. Replace these apps with better developed ones instead of continuing to drain your battery due to malicious or poorly written apps.

12. Extend battery life use battery saver mode

Most major phone manufacturers have their own versions of battery saving mode. They can automatically disable background tasks, manage applications, control settings, and more. Look in your settings, probably under the Battery section, to find out if your phone has something like this.

13. Root

Rooting is an advanced process that varies significantly from device to device. However, there is no doubt that a number of battery saving techniques are available to root users but are not accessible to non-rooted devices.

  • How to install TWRP recovery and root… find your phone
  • How to root… find your phone

14. Save Android battery by uninstalling unnecessary apps

Rooting will not extend battery life. Rooting simply opens the doors to your device's limited partitions and directories. With these restrictions removed, you can remove unnecessary applications (eg Operator's or OEM's Bloatware), especially those that run as background services, wasting precious battery power.

15. Underclock the device

With root access on your device, you can also install apps that can improve your system's performance. An app that controls the CPU, for example. Apps like these essentially allow you to change the CPU settings on your device.

It is possible to set the CPU frequency and stay at a lower level (and, consequently, consume less power but sacrifice device performance) or stretch the CPU to maximum limits (with better and faster performance, but at the price of producing heat, drain the battery quickly and make the system unstable).

16. Save Android battery by installing custom kernels and ROMs

And since, in all likelihood, your phone also has an unlocked bootloader and custom recovery installed during the rooting process, then you will also be able to enjoy - the blessings of power saving, in this case - of many custom kernels and custom ROMs. Check out the site for guides on how to install custom kernels or custom ROMs for your particular device.


Extending battery life is a simple matter of minimizing power consumption. As you can see, your Android smartphone has a lot of components that affect energy consumption. Optimizing these can range from simply changing the way you use your device on a daily basis and fully automating connectivity.

However, on the inside, the storage of the battery is very simple. I'll repeat my initial summary: let's dim the screen and disable any services you're not using. These two alone can go a long way in helping you finish the day with your battery still charged.
