Probably some apps are messing everything up, or maybe you need to change some system settings to get that new phone feeling back. It is 2018’s complete guide to save and improve battery life of your Android smartphone. With these battery saving tips, you can save and improve battery life on Android. Let’s start without wasting your battery life while you are browsing.

How to Save Battery on Android?

What to Change?

Before we start, I divided this guide into two parts, one is where you can change settings to keep your Android phone up & running, and the other is where you can avoid some things to save battery life of your Android phone.

Remember, that these settings options might be different from your phones. While writing this guide, I used my phone as a subject which is running on Stock Android Pie. You can find relevant settings in your phone’s settings. Let’s dig in.

You have to change some settings to stop apps & system from using a lot of battery life. Here are the settings you might want to look at again to keep battery usage healthy.

Display Sleep Time

Screen time takes the most of Android battery when you look at your everyday usage. The display is using the battery when its ON. You can limit the screen time by setting it to lowest and appropriate for you. For me, sleep time of 1 minute is fine, so more than 1 minute will leave your display ON when you are not using it and ends up in draining the battery. Navigate to Settings > Display > Advanced > Sleep and select less time.

Notification Settings

Notifications are also a big reason for consuming battery. Whenever a notification is received, your phone will ring, the display will turn ON and drains the battery. Now, there are many apps on your phone, and if plenty of apps keep sending you notification and waking screen. It means a lot of battery usage even though you don’t want that app to send notifications.

Here’s a quick solution, long press the notification and you will see options, select app info and turn off notifications for that app. if you accidentally swiped away that notification go to manage notification in Android settings and manage from there. (Recent notification only available in Android P). Navigate to Settings > App & notifications > Notifications.

Screen Brightness

When it comes to battery consumption, you’ll always find screen brightness at the top of the usage list. The screen uses a lot of battery. Too much brightness and your screen will suck the battery life out of your phone. So, choosing adaptive screen brightness or limiting the brightness to a reasonable level can save your battery on your Android phone. Navigate to Settings > Display > Adaptive brightness and turn ON adaptive brightness.

Adaptive Battery Mode

Introduction of Doze mode in Android Marshmallow was the first step by Google to improve battery life of every Android smartphone. With every API level, Google updated the feature with more features, and now it’s known as Adaptive Battery mode in Android Pie.

Adaptive Battery is one of the most loved and main features of Android Pie. With adaptive battery, CPU uses 5% less battery than usual. How does it work? Adaptive battery feature adapts your usage pattern and learns from your behavior of using apps. It purges the apps you use less and keeps the one you use the most in the memory.

Battery Saving Mode

It is the most effective of all. I use my phone at battery saving mode, and my battery never disappoints me. Especially in Android Pie 9.0, this feature works so well. What’s the magic of this mode?

Battery saving mode on Android limits all notifications, screen brightness, background processes, data consumption and what not. It also reduces the phone performance, but it’s barely noticeable unless you are playing a game or running a lot of apps simultaneously. I’m not a multi-tasker, so it helps me a lot.

Limit Background Services

With adaptive battery and battery optimization, the system will take care of background app activity by keeping the apps that you use the most in the memory.

But, I have a suggestion for you here. Let’s say you use Facebook more; adaptive battery feature will learn that you use Facebook more often. Now, we all know that Facebook, WhatsApp, Snapchat use a lot of battery and keeps using it in the background.

So, what I tried was, limited background data and app activity and now my battery life is a lot better than it was before. You can manually limit data usage of the app from “Data Usage” settings and “App activity” from the App info section of the particular app. It works like a charm. Also, turn off Wi-Fi scanning, NFC and Bluetooth to save some juice.

Location and Wireless Activity

Location is also one of the battery hungry features that you should take care of to save battery life. As we can control permissions in Android OS, you can check which app is using location more than others in the background. If it’s not Maps, you can turn off location access for that app and save your battery. Most of the times, apps like G-Maps and fitness tracking apps use the battery in the background. The problem is GPS & location services drain too much data. Keep these settings off, and you will see your battery usage decrease with time.

Turn on Battery Optimization

With the release of Android Marshmallow, doze mode and battery optimization for apps was a great start. You can turn on battery optimization for all the apps so that they don’t drain all of your phone’s juice. Just go to settings and search for battery optimization. Navigate to Apps & notifications > Special app access > Battery optimization and turn on battery optimization.

What to Avoid?

You have read all battery saving tips that you can change and save battery on your Android phone. Now, here are the things you should avoid to save battery and improve battery life.

Don’t Charge too Much

Charging a phone 100% means that you just completed one cycle of the battery. An average smartphone comes with 500 to 600 battery cycles, and after these cycles, the battery starts wearing off. So, to save battery, don’t charge it 100% all the time. It reduces battery life. Also, make sure that you keep charging your phone in between 50% to 30% of battery, don’t wait till your battery falls under 20% it’s not healthy for battery. Keep the balance and charge it often.

Avoid Extreme Temperatures

Charging your phone at an extreme temperature or using it can reduce battery life. It doesn’t just cut your battery life, it’s hazardous and not recommended. Excessive heat can make a battery explode. Remember Note 7 debacle? The battery acted like a bomb when the phone was overheating and resulted in the halt of Galaxy Note 7 sales.

Battery-boosting Apps

You might think that battery boosting apps save battery life for you. Instead they are consuming battery itself and running Ads to make it worse. They kill apps in the background and keep running their services to pretend that these apps are saving you some juice. Don’t fall in the trap of battery-boosting apps, why it’s a trap? Well, they’ll show you a very healthy battery and show you weekly report of “everything is fine” even your phone battery needs replacement. So, you can see yourself.

Task Killers

Task killers are battery drainers. It is not wrong to use a task killer that just kills unwanted programs running in the background, but an app that runs in the background itself to show you Ads and keep an eye on the apps that you are using is a nightmare.

Phones are becoming incredibly smart with every passing year. Software updates are bringing features that involve A.I and machine learning. Now, operating systems know what to keep and what to kill. So, it is useless to install an app killer that destroys even the programs that you usually need.

If you kill an app that you use the most, every time you load that app will take more battery. In other cases, the OS loads the app itself without completely reloading it. So, avoid task killers, or if you are really into killing apps, Greenify is the app that I will suggest. It works very well without root and is efficient in hibernating apps in the background. It’s such a treat for Android phones. Give it a try and if you want to try great apps and features without much work, you can read this post of cool Android tricks without having to root your phone.

Clearing the Recent Apps

You might think that clearing recent apps will save you a lot of battery life, but that is not the case. An unwanted app might save you some RAM, but if you remove an app, the next time it will reload again and take much more battery. So, don’t wipe away the apps that you use the most from your recent app list, today, operating systems are smart enough to figure out what to keep in memory and what to kill.
