Access to Root is great for modifying your system to work faster, smoother and pretty much work like a beast. You can use Root to change boot animations, add customizations and even improve data handling and speed.

There are many ways you can abuse your root access to tax the hardware of our beloved smartphones. Unfortunately, this does tax the battery as well, which leads to one of the most common problems of rooted users – their battery doesn’t last long enough to matter.

Fortunately, there are also things you can do with Root that will help you to improve the battery life of your android phone and making sure your smartphone is smart enough to last a whole day. These tweaks and apps are simply meant to help you on the software side. If you have a hardware battery drain problem, then you need to look elsewhere.

Manage CPU Speed

There are several apps in the Play Store that helps you manage CPU speed. Most of the time, these apps are associated with overclocking, which is making the CPU run at speeds faster than it was set by the manufacturer. This obviously provides a great boost in performance, but it also forces the CPU to drain more battery.

In situations where speed is not an issue, and you can work without the excessive power of your overclocked device, then the best thing you can do is to lower the maximum speed instead. By using the CPU speed manager to lower the actual speed, the CPU will consume less battery in the long run and allow you to keep the phone running for longer periods of time.

Manipulate Active Cores

To further augment the speed and power necessary to run Android to its fullest, manufacturers have baked in multiple core processors with every new generation of Android. We now have dual core and quad core processors in the market and pretty soon, it would seem that an octa-core processor will be added to the fray.

When you plan to keep your phone idle anyway, you can have an app like CPU Sleeper to turn off a core or two to make sure that your CPU can still perform its tasks, but consume less power due to the reduced number of active cores.

Force Deep Sleep

Deep sleep is a state where your phone is at its lowest setting, keeping the phone alive but barely. When in deep sleep, your phone consumes the least amount of battery since it only gets up on a periodical basis to check for SNS and Mail. The rest of the time, it keeps the sync and data use to a minimum.

During deep sleep, the phone stops multitasking or any running background app. This ensures that your phone won’t be consuming battery during that duration of time. Normally, our smartphones enter deep sleep on its own after a set amount of time when the screen is off. With apps like Dee Sleep Battery, we can force the phone to go to Deep Sleep immediately and even modify how long it will be in that state. This is perfect when you yourself have to sleep, or you don’t plan on using the phone much but still want it to be able to receive calls and messages.

Force the Screen Off

Now you may be wondering, why in the world would you want to force the screen off? There are certain situations where the screen is forcibly kept on even if it was not necessary. Situations like when you are connected to a TV to relay video or play games.

In these situations, pressing the power button to turn off the display also locks the screen and forces the running app to come to a halt. With root access, you can minimize the battery drain during these situations by keeping the app alive and working, while forcing the screen to be off. In case you didn’t know, the screen actually is one of the biggest battery drainers in an Android smartphone.

Kill or Freeze Unwanted Apps

For some people, some apps are just plain unnecessary. Still, the manufacturer figured it would be good to have some apps around. Unfortunately, some of these apps that we call “bloatware” are also draining your battery since the manufacturer likes keeping the app running in the background.

With root access, you can effectively kill and freeze these apps so that it won’t run on your phone again until you really wanted them to. This can help keep the battery alive by reducing the strain that the CPU and wireless communications have to exert in keeping these useless apps alive.
