Like any other smartphone, the battery works just like life in any Android Marshmallow smartphone or other smart device. Due to heavy reliance of smartphones upon the apps of differing sizes – their types, their typical purposes and their typical dependence upon the Internet for their smooth working of apps – the apps become main source of the battery drainage and the shorter life.

The best method for the prolonged life of battery is to save it from quick drainage and to manage the battery optimization for the apps. By battery optimization, you may control the battery for the usage of most important apps, i.e. the most important apps can be allowed to use more battery as compared to the less useful apps. By applying such control, you may manage your battery to supply more power to the apps which are important for the smooth working of the apps. In addition to it, you may set the preferences of the battery optimization apps, the usage of which may be delayed for some time.

Due to importance of the battery optimization for the different apps, Android has placed two different paths to approach the battery optimization; one from the apps screen and the other from the battery features. In this article, we have explained the method to approach the battery optimization from the apps screen. For the method to approach the battery optimization form the apps screen, tap or click to read our article about it.

In the Android Marshmallow smartphones and devices, you may set the battery optimization from a single screen, for the different apps. You may do it at your end, easily, but if you need guidance, see the instructions, given below:
