How To Improve Battery Life Of Your Android Smartphone

tips to improve battery life on Android devices

Despite smartphones getting more and more expensive, the battery life of most smartphones remains extremely embarrassing and even some of the high-end devices barely last a day or just a few hours if you are constantly using the internet on your Android smartphone. However, even if you are not tech savvy, there are ways with which you can increase the battery life of your Android smartphone and we will mention all the possible ways to do that below.

How To Make Your Smartphone Battery Last Longer On Android

While Android smartphones boast multitasking and Always on apps, there is a major downside to this and that is the battery drain which results in a significantly reduced battery life if you have a lot of apps running in the background. Despite their great battery capacities of 3,000mAh and above, these Android smartphones struggle with battery timings as compared to old mobile phones because of their large screens, bright colors and all the inner workings of the Android OS. Although Google does try to optimize battery timing with each update, there are some handy tips you can adopt yourself to increase battery backup provided by your Android smartphone with a single charge.

Background Apps

While they may not seem to be slowing down your Android phone, the number of background apps you have running on your device seriously impacts the battery backup performance. To facilitate quick switching between apps, the Android OS does not automatically close an app once you switch to a different screen or app. Instead, the app you were previously using goes in a standby background state so you can access your data just as you left it without the app having to load everything again.

Because of this very reason, it is generally a good idea to turn off apps instead of sending them to the background when you stop using them. With their fast processors, it doesn’t really take that long for the app to launch again but it does improve battery life. Originally, Android users had to download app killer apps from the Google store to kill background apps, however, Google has now included such functionality in their OS. Simply press the App Menu button and then just press the X next to the app name. While this solution is not always effective in improving battery life, it can work in the case of some, especially power hungry apps. Killing background apps also helps in extending battery life of smartphones running Android KitKat and Android Lollipop.

Some VOIP or messenger apps are also quite power hungry and not really worth the features they provide if they end up draining your smartphone battery in just a few hours. To make sure you have no such apps installed, go to Battery Settings and check out Battery Use to see which apps are resource hungry. If possible, delete those apps altogether and look for alternative solutions.


Google Assistant

The Google Assistant may be a handy tool for all sorts of reasons, the fact that it has to constantly “listen” just in case you might want to power it up by using voice commands means that it is also draining a lot of your Android smartphone battery. For that very reason, if you are at home or know that you will not be using the voice command features, it is a good idea to disable them altogether to considerably improve battery life of your smartphone.

Connectivity Features

Smartphones might be all about constant connectivity to the internet and the world around you, your smartphone battery is however not and connectivity options like WiFi and Mobile Data drain your Android smartphone battery faster than anything else. Combine these with other options like Bluetooth and GPS and you have a recipe for disaster where your battery life is barely half a day and requires you to either carry around a power bank or find an outlet to recharge your phone. If you aren’t actively using a service, it is best to turn it off. For example, if you are at home and have access to WiFi, there is no need to keep Mobile Data running. While the WiFi may trump over Mobile Data and doesn’t use up your carrier package, since the feature itself is active in the background it continues to use the battery. Similarly, in most cases, you don’t need GPS unless you are traveling so it’s a good idea to keep that disabled as well.

If there an option to use WiFi over mobile data, even if the WiFi service isn’t exceptional and you have an unlimited data plan from your carrier, it is best to use WiFi as the battery drain is considerably less compared to mobile data.

Another useful tip to ensure better battery life for Android smartphone is to go and enable “Always on During Sleep” in your WiFi settings if you stay at home a lot. This way, your phone doesn’t use extra battery connecting to a WiFi network whenever you turn on your phone display.

Similarly, other connectivity options like NFC, while useful, don’t really need to be used every time. Although NFC and Bluetooth may not use reduce battery life by a lot, they still contribute and every small percentage matters when you need your phone for the whole day and there is no way to recharge your device. If you know you won’t be using your Android smartphone at all for the next few hours, the Airplane Mode is also another useful way to ensure a longer battery backup as it turns off all wireless connectivity with just one button.

UI Settings

Android has a lot of flash UI settings and it might not seem like it but they are actually one of the biggest culprits behind reduced battery timing. One of those are widgets, which while highly useful are also a great threat to a longer battery life. Since most widgets need to constantly connect and sync with the internet, they continue to drain the battery in the background even if you aren’t using them. Social media and weather widgets are the worst as they constantly need to update, even if you aren’t currently using them or on the home screen where they are located. In most cases, it is best to remove them altogether.

The stock Android UI features itself don’t exactly favor longer battery life and fancy colors, app switch animations and brightness should also be kept in check if you want to improve your Android smartphone battery. The first thing you should start off with is Auto/Adaptive Brightness and disable it. In most cases, this makes the screen much brighter than it needs to be and thus is bad for the battery backup. Simply use the slider and adjust the brightness according to what you actually need. If you don’t always keep your phone in your pocket and don’t have notification volume turned down, disabling vibration and haptic feedback of the keyboard can also improve the battery.

Another useful way to improve battery backup is by turning off the phone’s auto-lock time. While this may not seem ideal as you will have to unlock your device after every few seconds if you set it aside for a bit, it does help with the battery timing to keep the screen awake as less as possible. Simply go to Display Settings and change Sleep length to 15 or 30 seconds instead of a few minutes.

To squeeze out the maximum amount of duration from your smartphone battery, there is always the option to use the Battery Saver mode of your smartphone. It is a one touch solution that disables all the fancy app animations and colors and limits background data so even if you use internet on your device, it doesn’t automatically sync them every few minutes and you need to actually open the app to sync emails and other similar stuff.

Combine this with the disabling of auto-sync from your Android settings and you can drastically improve your Android smartphone’s battery timing. Since you don’t need to constantly use Google Sync features like syncing your contacts across all devices, it is pointless to keep Auto-Sync enabled as all it does is reduce battery life. Simply disable the option from settings and then manually sync your data at the end of the day or whenever you actually need to.

While live wallpapers or even normal bright pictures look great as your homescreen wallpaper, they are also bad for your smartphone battery and another great way to improve android smartphone battery life is to simply use a black screen as your wallpaper. It may not look pretty but it is a great battery saver for big screen devices with bright OLED/SAMOLED screens.

Use Battery Save Apps

There are a lot of battery optimization apps for Android available on Google Play that are great for smartphone’s battery optimization. Some of the apps even clean the memory of the smartphone and helps you close unwanted apps that also helps in increasing battery life of your smartphone.

Power Saving Mode

Google has introduced battery saver mode in Android that greatly helps you in getting more battery backup out of your Android device. This mode has been optimized by Google in the upcoming Android versions, including the latest Android Oreo 8. Users of Android KitKat and Android Lollipop have also reported of getting a lot of battery backup by using this battery saver mode on their smartphones.


If you are tech savvy, you probably already know the benefits of rooting a smartphone. However, if you didn’t then rooting your android device is another great way to conserve battery as it can provide you with a variety of new saves to improve battery backup. Once your device has been rooted, you can dive deeper into Android systems and tweak a lot of settings. Most carrier locked phones come with a lot of bloatware apps that consume battery life and they should be the first to go once your device is rooted. Similarly, you can also underclock your phone to use less processor power when you don’t need it so that it drains less battery.

Since you have managed to Root your Android smartphone, you might also want to look into custom ROMs which are made by the Android community and a lot of them focus on improving battery performance since those users had the same issues with battery life when it comes to regularly used Android firmware.


While most Android apps just boast about improving battery performance, Greenify is one that truly stands out as it actually improves battery life. Greenify allows you to put apps in hibernation mode when they are not being used so they consume little to no battery. Since Greenify allows you to customize which app is hibernated, it is a really useful tool to select apps which would otherwise be ignored by the Android OS and would still continue to work in the background to send you notifications.

Go Idle

While smartphones are extremely important to our daily lives, not only is it not healthy to constantly stare at the screen of such a small device for longer period of times but it also bad for the battery timing to have your screen constantly on, or simply the smartphone working in the background. For such reasons, it is a good idea to sometimes either completely turn off your smartphone when you are at work or about to sleep/ take a nap. If these aren’t an option, you can use the Do Not Disturb mode on your device to set timers for when you are at work or traveling. When the option is enabled, the smartphone goes into a deep sleep state and does not ring, vibrate or connect to any networks which saves a lot of battery life. Apps like IFTTT can automate this process for you with a lot more customization options.


Apps and your Android OS will constantly receive updates and it is generally not a good idea to skip out on those. Most of the times, these small upgrades are designed to remove bugs while also optimize the apps or the OS for better performance. This better performance includes battery optimization and it is possible that a particular power hungry Android app will end up behaving normally after an update. For this very reason, it is best to update your apps and Android firmware as soon as possible and it might actually end up helping you improve battery timing of your device.

So there you have it, some handy tips to get the most out of your devices and Improve Battery Life of your Android Smartphone to ensure that a single complete charge lasts you at least one day so you don’t run out of battery while at work or traveling.
