Battery Guru

Battery Guru is a battery-saving app that gives you an estimate of its remaining charge (like many other apps) and helps you increase its duration.

Using Battery Guru is simple. When you open the app, you'll see a quick analysis of your battery, including its temperature, state, and charge. There's also an optimization function that helps you improve your battery's performance. With just the tap of a button, you can see how well your battery is operating and how to improve its performance. The optimization feature breaks down which apps are consuming the most resources and gives you the option to close them. It also includes several shortcuts to classic battery-saving methods, like turning off WiFi and Bluetooth, lowering screen brightness, deactivating vibrations, and more.

Although all the features included in Battery Guru are interesting, the option to kill processes is a must-have when it comes to saving battery, since most people keep many apps running in the background. Even if you're not using an app, it continues to consume battery as long as it's open. But you can take care of this in a snap with Battery Guru. Not only can you check how much battery time you have left, but you can also check how long your battery will last if you perform certain actions. For example, you can see how long your battery will last if you watch a non-stop stream of YouTube videos.

Battery Guru is a good tool for calculating your smartphone's battery life, which you can also use to optimize its performance.
