[UPDATED][TUTORIAL] Have better Battery Life on TW 5.1.1

[TheForgotten]

With this guide, I was capable of having my phone on for 3 days with 1h of screen-on time, and 7h of screen-on time with YouTube and WiFi turned on.

I WON'T PROMISSE YOU YOU'LL HAVE THE SAME BATTERY LIFE I DID, BUT I'LL GIVE YOU THE STEPS I TOOK TO HAVE IT.
I'M NOT RESPONSIBLE FOR ANY DAMAGE THAT MAY OCCURR TO YOUR DEVICE.

With which ROM/ROMs is this tutorial compatible?

Theoretically, this tutorial is compatible with any TW 5.1.1 ROM based on MotionROM, but it was only tested in Project Lucky.

What do we need?

First, we need to have Xposed Framework installed. We also need root acess, but that comes pre-installed in the ROM.
Apps we need:

• BatteryCalibration
• GravityBox [LP]
• Greenify (Donation Package)
• PowerNap

Setting up the apps:
Greenify

First, we'll disable the auto-hibernation, because that's eats some of our precious battery. After that, we need to go to "Experimental Resources" and change the working mode to "Impulsive", then check the "Apply Greenify to system apps" and "Reveal hidden synchronization" (you can check some of the screenshots bellow).

Now, the rest is very easy, I'll give you guys a list of safe system apps to hibernate, and you simply need to hibernate those. And also, hibernate every 3rd app you install (except PowerNap), specially chat and social networks apps, those are the most battery hungry.

• Calculator
• Cloud Together
• Camera
• E-mail (both)
• Studio
• Galaxy Apps
• Galaxy Essentials Widget
• Gallery
• Smart Manager
• Google Play Store
• Voice Recorder
• Internet
• Magnifying Glass/Magnifier
• Music
• My Files
• S Planner
• S Voice
• Samsung Notes
• Exchange Service
• upday (unless you use the launcher page)
• Video
• Weather (unless you use the weather widget)

PS: this list was taken from Project Lucky, because it's the ROM I'm currently using.

________________________________________________

PowerNap

This one is very easy to configure. All we need to do is activate "Endurance Mode" and then tap on it. Now we tap on "Activation" and we drag the green ball all the way to the right, and check the "Enable while charging" box (you can check some screenshots below).

________________________________________________

GravityBox [LP]

Now, this one has some more steps comparing to the other ones, but it's very simple too. Go to "Display Tweaks", then "Brightness Settings". Activate it and then put the "Minimum brightness level" to 1 (check the screenshots below if you need).

Configuring the kernel:

If you didn't flash SkyKernel by @SoUnd001, then do it before following the next steps. You can download it here. To configure the kernel we're gonna need an app called Kernel Adiutor. To be able to run this app, we need to have BusyBox installed. If your ROM doesn't come with BusyBox pre-installed, you can install it using an app called BusyBox. So, with the app open, we need to go to the "CPU" tab and change the "CPU Governor" from "ondemand" to "smartmax", then tap on "CPU Governor Tunables" and change the value of "enable_boost_cpu" to 0. Now, we must go to the "CPU Hotplug" tab and change the value of "CPUs Boosted" to 2 and the value of "Boost Lock Duration" to 1. Now, go to the "GPU" tab and change the "GPU Governor" to "simple_ondemand" (if you need some help check the screenshots below).
PS: in some cases, you'll lose root when you flash the kernel. To fix that, simply flash this.

Other tips for a better battery life:

• Disable any kind of synchronzation
• Disable WiFi, Mobile Data, GPS and etc when you're not using them
• Keep Power Saving Mode always on
• Keep the phone's brightness at the minimum possible
• Keep auto-brightness disabled
• Reboot your phone when you unplug it off the charger (connecting to the PC applies to this too)
• Uninstall any app related to Facebook, like Facebook itself and Messenger

I have lose root after flash of kernel

I have lose root after flash of kernel

That happens if you flash the kernel. But to get the root access again, simply flash this.
And btw, thank you for reporting that bug that I known but I forgot. Anyway, that information was added in the thread, so if anyone experience that bug too, they'll have the solution in the thread

But again, thank you

"Disable any kind of synchronzation

Keep Power Saving Mode always on
Keep the phone's brightness at the minimum possible
Uninstall any app related to Facebook, like Facebook itself and Messenger.".....
Hahaha...its easyer to simply Power off the phone��
For ME ,skype,FB,viber,email was minimum to alltime runs on device.
Some tips to battery save:
automatic brightness off...change it manualy because sensor drains batt.
If not bánt fast drain simply disable mobile data ....wifi on 24h US aproximately 8-10mah...useless to disable if not connected at any Network...
With thats, with factory batt u rease circa 4-4.5h of screen on time ,at 75%wifi and 25%mibile data use.
Cpu settings not significantly influent the battery drain.Just overclock or power draining governor mode was result fast drain.
My suggestion is: ondemand or factory...
io: @tw use factory settings... @CM bfq 512M or 256M.
GPS was not significantly results draining.
Extra sized battery not recommended because kernels not able to correct use of it... just with replace it and restart the phone was resulting longer using time... my 7200mah anker after 3 replace and restart, results circa 3.5days and 10-12 h ours of screen time... of course with higher mobile data using this times was shorter.
I hope thats helps anybody ��

Bro, if you simply turn off your phone, you won't receive calls.
Thank you for reminding me of the automatic brightness one, I really forgot about it
And yes, CPU Settings will influenciate the battery a lot. You really don't know how governors work, right? And with those instructions, I disabled the CPU Boost, a function that's not needed in most of the cases. And yes, overclocks and the "power draining" governor aka performance governor drains more, but every bit of battery is precious.
And btw, bro, OnDemand is the factory CPU Governor. Please do some research before posting.
But, anyway, thank you ^^
