Mine was going down pretty quickly, too. I had this app on my last phone and installed it again on the N3. So far, so good. Battery drain has gone way down.

I don't know what all this stuff about great battery life is and I guess my "intensive use" is not the same as other peoples'. Under intensive use yesterday, mine lasted five hours. "Energy Saver" was on. But then I'm used to phones that last at least two days between charges so I'm ignorant if underwhelmed.

It was mostly but not exclusively tethered to a camera yesterday and sucking small JPGs off a real camera. (I did have a spare battery in my pocket.)

I had this problem at first. Check to see if you have the option to say "hey Galaxy" with the screen off and have it go to S Voice. That thing KILLS battery. Once I turned if off, I had no issues.

If you go into S Voice Settings, there's an option for "Wake-up". Turn both of those options off and you should be see immensely better battery life.

@Lee5000
It's been recommended for the past 3-4 years now to not use Task Killer apps since it's accessible in the onboard software. I'm not a techie and can't remember the developers reasons for this.

Top,

I've never heard that. I've used this app on my previous phone (Galaxy Nexus) for two years and never had any issues (that I knew of). Thanks for the heads up, though. I'll definitely watch for anything unusual.

I was curious to revisit this topic and found an older piece from 2011 about reasons not to use third party task killers. Remember that it may not cause any immediate effects but if it does over time will you screw up your Android systems checks & balances to tweak your phone for optimal function. You could possibly mess up your phone in the long run and factory resets are pretty undesirable when you have all apps, files, photos, music, calendar events and special settings established over time. Is it worth the risk? You make the call but at least look at the reasons behind your decision.
