Greenify for Android a must-have to increase battery life!

Like most smartphone users, I crave more battery. Battery can be conserved by disabling all push notifications as well as location services, active screensavers, turn off radios not being used, etc. Even then, some programs insist on loading themselves into memory and eating your nanos and battery. There are programs that will auto-kill apps, but that can actually eat CPU time as well as the killed apps continually try to reload.

Virtually all social media apps load themselves, but so do most browsers, news apps, even shopping apps. Facebook and Google+ are amongst the worst offenders, but ESPN Score Center seems to want to vie for the top annoying position. It’s absurd that these programs always want to run in the background, eating your nanos and battery.

Enter Greenify. It doesn’t kill apps, but hibernates them. You can still call them back in the same state in which you left them. But in the meantime, they don’t eat your nanos or your battery. Awesome idea.

Greenify itself will automatically hibernate the list of user-installed apps that you specify. To hibernate system apps, you must use the donate version in combination with Xposed. Xposed is a framework that allows system changes to Android without having to flash new ROM pieces. It sounds scary, and should be used with caution, but actually works well. Be sure to read the background and instructions at this link.

Don’t Greenify everything. Nothing is free and Greenifying the wrong apps can cause issues with them. That’s especially true for system apps. For example, using the donate version of Greenify with Xposed, I added Google Play services to the hibernate list because is seemed to eat more nanos than warranted according to System Tuner Pro. That started some bizarre Android behavior until I took Play services off of the list. So far, that’s the only issue that I’ve encountered.

Does it work? You bet. Using Better Battery Stats, my Galaxy S3 ate between 2.5% with virtually no usage and over 4% of the battery per hour of normal use on a good day. A bad day could run 8 – 9%/hour or higher. Disabling location services and all push notifications helped, but I was still stuck with 3 – 4%/hour on a good day. With Greenify, battery drain dropped to less than 2%/hour consistently in my normal daily usage pattern tested for over a week. That’s about a 50-100% increase in battery life!

Greenify is a cinch to use, sporting a very user-friendly interface and good help available. I highly recommend Greenify, especially the donate version, as a valuable tool to speed up your phone and increase your battery life.

  1. I just got an android phone, so I really appreciate this advice. :)

    • You’re welcome. I wish that I’d found this earlier. Unless you need them, you should also turn off all location and push/polling notification services. These keep the radios hopping, with really eats the battery life. You can usually find the necessary controls under “Settings” for the individual apps. The only exception I’ve found is Yahoo! mail, which doesn’t seem to have a way to turn off its automatic mail checking routine. Also, if it will work for you, don’t routinely use the automatic screen brightness but set the screen to a relatively low brightness for routine use. The auto brightness is generally brighter than it has to be indoors, which is where most of us spend the most time. I only use it outdoors when I need it.

      I really enjoy Android’s flexibility, configurability, and stability.

  2. […] The only issue that I’ve encountered is that the Privacy Guard icon and notification remain after the program that invoked PG has closed. I haven’t seen this before, but it’s a minor annoyance. All my apps seem to work fine, including Greenify and Xposed. […]
