Honestly, most battery saving apps don't save that much power to be worth it without disabling a lot of features on your phone, at which point, you might as well not have a smart phone.
That’s not the case with Hibernate – Real Battery Saver app by Realistic. By choosing to Hibernate particular Power draining app, settings and CPU; it automatically stops these apps and setting to execute their tasks when the phone is in sleep mode, i.e. screen is off, and when you use your phone again, these apps and settings gets back to their normal task, without any need of checking/unchecking, with no interference in your day to day task to provide you; more power and smooth experience of using your smartphone.
It’s a simple, elegant and awesome single screen app where you have three hibernation settings, one is Application Hibernation Lock, Second is CPU Hibernation Lock and the third is Setting Hibernation Lock. You can easily scroll through these settings. In that way you don’t have to search or navigate throughout the app for any setting; to make app experience easier.
Let’s talk about first setting which is “Application Hibernation Setting”. This setting hibernates (disable) the app which are executing their task in background and also consuming battery in the process. It’s fine if these apps are running when you are using your phone and it’s necessary to have the experience of a smartphone. But when you are not using your phone i.e. phone is in idle condition or simply we can say in sleep mode, you don’t want these apps to drain battery. That’s what this setting do; stop these battery draining apps to consume battery so that you could have more battery power in your phone whenever you use it.
Second setting is “CPU Hibernation Lock”. CPU is “the brain of android” constantly computing many demanding tasks like updating apps, widgets and checking for software updates.
