Best Android battery saver apps

People think of replacing their mobile device with another one when they are not happy with the performance of its battery or apps. Let’s talk about the battery, one of the most critical components of a phone/tablet. No matter what the mobile OS is, the low capacity or a defective battery is a frustrating problem. The battery starts draining when you switch on your mobile device. Display, games, and apps are the top three power-wasting modules in an Android device. Games require more GPU and SoC processing power than regular apps to deliver a good user experience. They also consume a massive amount of RAM. Apps running in the background may execute some tasks (Ex. Cleaning junk, syncing files, etc). Hence, they’re also responsible for the poor performance of the battery. You cannot use apps or play games on a smartphone without a display. Thus, you can’t fix the “display draining battery” problem on Android. Apart from Android OS features, games, and apps, people are also liable for the “battery draining problem”.

While using a browser, some people open multiple tabs and forget to close the tab after using the website. They also fail to turn off the mobile data/WiFi connection before bed. These two things can completely drain a fully charged battery of a phone/tablet within 5 to 6 hours. I’ve shared just a few reasons. Several other factors may cause a battery to drain fast. Software/configuration-related issues can be fixed with a good Android battery saver application. Below, I have shared the list of the best battery saver apps for Android. These applications will make your mobile device last longer on a single charge by killing idle processes, reducing CPU usage, and fixing many other issues automatically.

Best battery saver apps for Android

Lux Lite

lux lite battery saver app for Android

Lux is an app that makes the phone’s display eye-friendly. It automatically adjusts the temperature and brightness of the screen by detecting the intensity of sunlight. It uses the ambient light sensor of the phone. Suppose you set the screen brightness to 75 and keep it unchanged. The screen content is easily readable in the daytime if you set the brightness to 40 to 50. The battery’s power will drain fast because of the unnecessarily high brightness level. Once you enable Lux Lite, the app will keep the screen’s brightness at an optimal level. It will thus save battery power. I have used the Lux Lite battery saver app on an old Android phone. The application works like a charm. Lux runs in the background. It consumes a low amount of RAM. Also, it doesn’t waste processor cycles.

The free version of AccuBattery provides a smart charging/charge alarm feature. It has a phone cooler function which reduces the mobile’s temperature by killing active apps of your choice.

Final thoughts: Android is a superb operating system. Google releases Android updates often, but unfortunately, none of the updates have helped users fix the battery problem in old phones. Users have to rely on battery-saver applications for the same. If you want to improve your phone’s battery backup free of cost, install one of the applications I’ve shared above. What if you own a new smartphone? New phones have 3000+ mAh battery which lasts long. If your new phone’s battery discharges quickly, the above applications will come in handy.

Note: Batteries wear out over time. If the phone is old and none of the above applications work for you, replace the battery or flash a new Android ROM.
