For a long time that the Android denounces you which apps have used the most battery since the last charge, but it is difficult to draw any conclusion: maybe some specific configuration made by you have made the software more “gaston”, for example. Android 8.1 Oreo’s will help you diagnose these problems.
Google redesigned the settings screen of the battery in the next update of Android. When you enter it, you can view the current load, estimated time remaining, and immediately below, an application that is spending a lot of energy — along with the reason. In the example, the Google Maps Preview is draining the battery by ordering the location with frequency:
Just tap once on the name of the culprit, and the Android will suggest a change in the settings to avoid that the battery dies so quickly. In this case, released by the Android Police, the only recommendation was to totally prevent the beta of Google Maps — to access the GPS, it can even resolve the problem of the battery, but it makes the application through… useless.
The Android will also show when an application is “waking up” your smartphone with frequency — for example, requesting an update in the background even with the screen turned off. This undermines the functioning of the resource Twelve, available from the Android 6.0, which decreases the power consumption when the unit is in standby.
The upgrade to Android 8.1 Oreo also comes with processing neural networks with hardware acceleration, optimizations for smartphones with limited RAM (1 GB or less) and refinements to the visuals. He is expected to be released until December, and starting with the Nexus devices and Pixel.
