Before we go straight to knowing why your Android system draining battery very fast, you should know that the Android system is designed in such a way that most of the system applications and services are needed to run continuously in the background.

The main reason for Android battery drain is improperly optimized apps and there are many reasons for battery drain problem, but most battery drain segments are often Android OS itself.

So, now the question is how to fix it? Well, there are some techniques which will solve this issue. let’s discuss one by one.

Uninstall The Apps Which Causes Your Android System Draining Battery Problem

If you find your Android system draining battery regularly without any use. That means something eating up your battery without your knowledge. Don’t worry, you can fix it by optimizing some phone settings. But first, you have to know how to enable ‘Developer Option‘ and second check ‘System Running Apps‘.

1. Enable Developer Option

Directly go to settings and search on top of settings – [About]

In most versions of Android, open [Settings] > [About Phone] > [Baseband & Kernel] > [Build Number] > Press 5 times on Build number option to enable ‘Developer Option‘.

But if you are already turned on ‘Developer Option‘ it will show you this message – ‘You are already in Developer Mode’.

2. Check System Running Apps

Directly go to settings and search on top of settings – [Developer Options]

In most versions of Android, open [Settings] > [Developer Options] > [Running Services]  Check all system running services which are running in the background.

Caution: Don’t delete any system process otherwise your Android OS may crash.

3. Check Which Apps Are Draining Your Battery

In most versions of Android, open [Settings] > [Device] > [Battery or Settings] > [Power] > Battery Use to see a list of all apps and how much battery power they’re using. In Android 9 or 10, it’s [Settings] > [Battery] > [Power Usage].

You can now see the percentage of power usage and the power consumption analysis apps that use the battery when tapped (Foreground, Background and Power Consumed). Also, you can check the power consumption of previous days.

4. Uninstall The Apps That You Are Not Using That Causes Your Android Battery Draining Problem

In most versions of Android, open [Settings] > [Apps] > Tap on each app and hit Uninstall to remove it as well as any data and cache it has created. (In Android 9 or 10, it’s [Settings] > [App management] > [App List] > Tap on each app and hit Uninstall to remove it as well as any data and cache it has created.)

Keep Your Apps And System Up-To-Date

Here are several reasons to update your applications and your system. New updates include new features, bug fixes, speed up the performance, but the most important thing is the security perspective. You can also read what’s new in the latest update. Let’s talk one by one what is the benefit of updating your applications and how system update can fix your android battery draining fast problem.

The most valuable benefits of upgrading your applications and system, including new features, come from the App developer or the company.


Human means there is a bug, so even though development apps have bugs, this will affect performance and usage and other bugs such as unexpected shutdowns. If you are updating your applications, those updates will correct those errors and may improve overall performance.


We all give the value of our time if you are using an app and it is not performing according to your expectations. It creates a headache for us because you need to keep your applications up to date, they will load faster so that you can do your task more efficiently and can fix your android system draining battery problem.


In our personal lives, we all place the highest value on our security, so why not put the value of our devices such as smartphones, laptops and tablets? Security is the main reason to update your applications. We know that the cyber threat is constantly evolving and also attacks your applications. Your applications are more sensitive to cyber-attacks. If you are using outdated applications, which makes you vulnerable to cybercriminals. For your safety, you should also keep your applications and system up to date.

To update of your apps, click on [Play Store] > [My apps & games] > [check for updates] or it’ll show you if any update has pending.

To update of your system, open [settings] > [Software Update] > you can see if any update has pending.

Android OS Is Smart Enough, You Must Not Close The Background Apps Manually

It’s a big myth and we also believe that closing your apps may not consume battery or resources, but technically you could be doing more damage to your phone except your sanity.

This is Hiroshi Lockheimer, Senior Vice President of Platforms and Ecosystems (Android, Chrome OS, Play) at Google. Someone asked if Android users should forcibly or manually close their smartphone apps or not. He says that the Android operating system is smart enough to manage system resources and Android is designed when an application is in use and when it is in the background and when it needs to be suspended, Android does it automatically if you do it manually, it takes more battery power and memory resources to restart those apps. You should only force close a background app when it is not responding. If you want to fix your Android system draining battery problem, stop forcibly closing background apps.

Reduce Screen Timeout And Turn Off Auto-Brightness

The biggest cause of Android system draining battery problem is the display backlight. Your phone’s screen consumes between 35% and 40% of the battery. But a newer screen like AMOLED offers a slightly better power consumption rate. Which means screen wake-up time is shortened, battery usage is reduced, and most Android phones have an automatic brightness setting and use a light sensor to adjust the backlight.

To maximize the battery life of daily use and to fix Android battery draining fast problem, there are two important settings here: Brightness and Screen timeout.

If you do not move indoors to outdoors frequently, turn off auto-brightness so the light sensor does not use the battery.

To disable auto brightness, open [settings] > [Display & Brightness] > [Uncheck/disable auto brightness].

Now also check the Screen Timeout option. Control the screen to turn off when not in use. By minimizing your screen timeout to less than a minute, you can make a big difference.

To minimize screen timeout, open [settings] > [Display & brightness] > [Auto Screen Off ] > Set your time under [1 minute] (30 seconds is better.)

Turn Off Unused Vibrations

By default, gentle vibrations also called “haptic feedback,” are turned on. On the keyboard, “haptic feedback” was also activated and a good amount of battery is needed because we type more during the day in chat. The vibrator that vibrates in your phone requires electricity to drive the small motors and the energy required to function is taken from its battery. Turning it off can save a significant amount of battery consumption, thereby improving the battery life of your phone. You must disable “haptic feedback” in the phone’s default accessibility settings and also on the keyboard.

To disable haptic feedback for the default phone settings, go to [settings] > [Additional settings] > [Accessibility] > [Vibration and haptic strength] > disable [touch feedback], [ring vibration] and [notification vibration].

To disable haptic feedback vibration of the keyboard, go to [settings] > [Additional settings] > [Keyboard & input method] > Choose your keyboard [Gboard] > [Preferences] > Turn it off [Haptic feedback on keypress].

Activate Smart Power Saving Mode.

If you have this feature on your phone, congratulations. The intelligent power saving mode will intelligently analyze your usage and detect when you are sleeping and doing other activities. It will intelligently identify the running status of applications. It will close some apps in the background when not needed and this mode will stretch the battery as much as it can. Puts your phone into deep sleep mode when idle.

To enable Intelligent Power Saver, go to [Settings] > [Battery] > toggle [Intelligent Power Saver (Recommended)]

Turn Off High-Performance Mode If You Are Not A Gamer

Not all the phones have this option but if you do, you should activate “high-performance mode” when you want to take full advantage of the operations on your phones, such as games and video streaming. It will give you the best experience. But it will drain the battery quickly and can cause overheating. When not necessary, always disable this option so that the battery does not drain quickly and can fix your Android system draining battery problem.

To disable High Performance Mode, go to [Settings] > [Battery] > toggle [High Performance Mode]

Avoid Live Wallpapers

Yes, a live wallpaper impact is more than just static wallpapers on battery. As we discussed, the most common reasons why the battery drains are the screen and the processor. While using a live wallpaper, it demands constant action from your phone’s processor and also GPU (Graphics Processing Unit).

Technically, live wallpapers don’t consume a lot of power if they are well coded or designed. If you spend a lot of time on the home screen with live wallpapers, the screen, the processor and the GPU will affect the battery life. Try to avoid live wallpapers because they lead to considerable battery drain.

Turn Off Radios

The new smartphones and tablets include multiple wireless radios. Wi-Fi radio; GPS; NFC; and Bluetooth; etc … all these radios will drastically reduce the battery life of your phone if they are not used and managed intelligently. You need to turn off the GPS, WiFi, Bluetooth, NFC when you are not using, it can help you improve the battery life of the phone.

As Per Power Usage



GPS: (Global Positioning System) consumes a lot more battery than anything else on your phone. Your phone’s GPS must communicate with three or four satellites at the same time. The GPS chips are on all the time continuously and the GPS prevents your phone from going to sleep.

WIFI: Wi-Fi (Wireless Fidelity) uses less power than GPS, but Wi-Fi uses more power when it is transmitting, Wi-Fi has a low power mode where the receiver only turns on for a short period every 100ms or if there is an incoming packet. Wi-Fi is capable of transmitting a signal much farther.

BLUETOOTH: Bluetooth power consumption depends on the specific use. Streaming music to headphones consumes more power than a connected smartwatch or location services like IPS.

NFC: NFC (Near Field Communication if you use NFC many times during the day, then it will have an impact on the battery life, otherwise if it is enabled, it will not have a big impact on the battery life.

AEROPLANE MODE: Technically, Airplane mode disables all wireless transmission functions, such as cellular radio, Wi-Fi and Bluetooth, GPS.

Airplane mode is very useful when you are on the ground and want to save battery life. The moment you turn on Airplane mode, a device’s radios stop and use a large amount of power to communicate with cell phone towers, scan and connect to nearby Wi-Fi networks, Bluetooth connections, and also for GPS.

Use A Dark Theme

The Dark theme is available in Android version 10 and higher.

Why Should You Use Dark Theme?

  1. It can significantly reduce power usage on devices with OLED or AMOLED displays.
  2. If you know the pixels then you can easily understand it. When the background is white, all the pixels are lit and the screen demands more battery power. When the pixels are black, as is the case in dark mode, the screen’s power requirements are significantly reduced, so you can improve the phone’s battery life.
  3. Another benefit of the dark mode is that you away from harmful blue lights and reduces eye strain and makes it easier to use a device.

Why Should Not You Use Dark Theme?

  1. If anyone suffering from #astigmatism they don’t feel great if dark mode is turned on.

How To Enable Dark Theme

  1. Check Android version: open [settings] > [About phone] > [check version] (Android 10.)
  2. If your Android version is 10, go to [Settings] > [Display & Brightness] > [Dark Mode] > Turn it on


Some other tricks which can also fix your Android battery drain problem

Charge Your Phone Between 30 To 80 Percent To Avoid Degrading Your Phone Battery

According to #Battery University, if you charge your phone 30 to 80 per cent, it puts the least amount of pressure on the battery and prolongs battery life. Now the question is why charging between 30 and 80 per cent is better for lithium-ion batteries. It is due to the high voltage that stresses the battery and the low voltage is good for the life of the battery. Therefore, partial charging or regular recharges are much better for lithium-ion batteries and can improve the life of the phone’s battery.

And try to avoid idle charging or charging overnight, as continuous trickle charging of a full battery can lead to lithium metal plating, reducing stability.

But it is a big myth that leaving the battery plugged in overnight will overcharge the battery, but the truth is that modern devices are smart enough to manage power and will reduce the amount of current after a 100% charge.

Avoid Extreme Of Heat And Cold From Your Phone.

Yes, you listen right, extreme heat or cold of your phone will affect the battery and also the performance. Temperature, as a critical factor, significantly affects the performance of lithium-ion batteries. According to Battery University, the allowable operating temperature limits for charging and discharging are different.

Charge Temperature

In lithium-ion batteries, the charging temperature is limited. For best results, the charging temperature region for consumer electronics is typically 10 ° C ~ 30 ° C. Temperatures outside this region will lead to performance degradation and permanent damage, such as lithium plating and thermal runaway.

Discharge Temperature

Lithium-ion batteries designed with high energy density and power density shows good performance in many different areas. But performance is still limited. The acceptable discharge temperature region for consumer electronics is typically -20 ° C ~ 60 ° C. Temperatures outside this region will lead to performance degradation and permanent damage, such as lithium plating and thermal runaway.

Warning: Do not put the phone under the pillow because when heat builds up during charging, it does not allow heat dissipation and causes the battery to explode. Here’s #news when a 14-year-old girl lost her life in Bastobe, Kazakhstan, because she left charging a smartphone under her pillow.

Playing Intensive Games Or Watching Videos While Charging Is Bad.

It is common sense that if you try to multitask, you will face more mistakes and less creativity. Like when you use the phone while charging, that means you are using power and no doubt that will simply slow down the charge.

If you texting while charging, it won’t consume much power. However, playing intensive games or watching videos will drain your battery. Using a phone while charging can cause the phone to overheat and there is also a risk of explosion.

For faster and safer charging, simply leave your phone alone while it charges. So that it can  improve your phone’s battery life.

Always Use An Official Charger

Always use an official charger, using an unofficial charger will damage your battery together with the phone. Official charger designed at a particular voltage to charge the device. Unofficial chargers are often made from poor quality components that do not meet the safety regulations of your country. It can cause electric shock and even fire.

Also, do not use third party cables to charge your phone. All cheap cables have thinner wires so they can’t charge as fast and they don’t support fast charging. It is recommended to buy charging cables rated of 2.5A or higher.

The most important is your LIFE, So please don’t use an unofficial charger.
