OK noob alert..

Will this work for a international UK unlocked model?

I'm running the official stock kit kat build.

Only ever unlocked, rooted and put a custom rom on my old Nexus 5 which by its nature was dead easy. From what I've read Samsung like to lock things down a lot these days.

Not sure but you can check the thread out. It does seem to work on a lot of different devices though. I'd say make a backup and give it a whirl. Push comes to shove, you can always go back to your backup.

It made a HUGE HUGE difference with my battery life.

Thanks, checking it out now.
 
So I have to "root" my phone to get battery life that I should anyways?

LOL Samsung/Touchwiz
 
Had this phone since launch and still love it like day 1

Althiugh battery hasn't been great yesterday.
 
Are you using Greenify as well as removal of the wake lock spinedoc posted?

I'm not using Greenify, I'm pretty happy with that last tweak. I listen to streaming music for my 2 1/2 hour lunchtime workout. Between the morning at work and my workout my battery would be 60-70% by the afternoon. After the tweaks my battery is closer to 80-90%. I don't even use my phone that much, I think it was just wakelocking a lot in my pocket.

I installed greenify and removed the wakelock last night. My phone was at 86 percent. When I woke up this morning, it was still at 86 percent.
