I have a few apps that definitely will hurt the battery if left running...so greenify let's me still have those apps and not worry about them impacting my battery. To me greenify is on my must have list. 😉
And to backup another's post, yes...the N5 CAN have battery life that rivals other great battery life phones. I get over 24 hours with 6 plus hours screen time easily. But...its all about how you set up your phone...and how you use it. "Average" battery times are hard to compare, since we all are setup different and do different things with our phones.
But yes, battery life CAN be brilliant.... Or it can be average.
