[AT&T Galaxy Note 3 General] altrikdout21:
Hi all,

I've spent some time in the battery life thread, seeing what usage times people are getting and how varied they are. Through testing different ROMs and set ups, I've found what works for me and I'd like to share it. I'm averaging at least a day in run time, with 6-8 hours of screen time. I've pushed my phone to 2+ days with 10 hours screen time. Here's how (universal tips, should work for anyone regardless of ROM):

1. MY SET UP

This should give you all a good idea of my set up. On paper it's a power user set up, but I still get amazing battery.

KNOXraid JB, though I get similar results on stock 4.3

Wifi/GPS/Bluetooth on 100% of the time

Data toggled on when needed

Power saving mode always on (I see no noticeable lag)

Sync always on, 2 Gmail accounts

Samsung Galaxy Gear always connected via BT (10+ hours every day)

Poor LTE signal always, between 1-2 bars

Blocking mode enabled to turn off LED and block notifications from 9pm-6am.

Nova Launcher Prime instead of Touchwiz Home

2. PROPER CHARGE

This is probably one of the most important aspects of battery life, yet few people talk about. Here're my steps:

(note: these are just MY steps--others may recommend otherwise, but this is what has worked for me)

Step 1: You've flashed a ROM, or simply turned on your phone out of the box:

Let the battery drain all the way to 0, until it shuts down completely.

Remove the back cover and take the battery out (~5 min is what I do)

Put the battery back in and charge all the way to 100% while the phone is OFF

NOTE I only use the original USB3 charger with the wall outlet--

never

through a USB port on a laptop.

Turn the phone on by holding the power button

Restart the phone once, wait until it says "Charged" on the lockscreen, then unplug

Step 2: After you've done this, you can charge your phone normally. I do the battery pull and full charge once a month or so.

3. SETTINGS

5. ROM IMPACT

This one is up to interpretation, but KNOXRAID v2.6 has given me about a 20% increase in battery over stock.

I installed it into Rom Slot 1, still have TW on my Stock slot...

Keep in mind though, YMMV!

6. OTHER MODS

Here are any other modifications I've made to my phone...

I rooted with Kingo Root

Installed AOSP Camera, so I have both AOSP/TW cameras

note: I froze the TW Gallery, I just use the AOSP Gallery instead

Xposed Framework + GravityBox (just to change battery icon)

Installed S-Voice onto KNOXRAID (I like it, haha)

64gb Micro SD, Photos and Videos saved to that instead of internal storage

Replaced Google Maps with older APK

I DO NOT USE GREENIFY AT ALL

Hopefully this post helps someone somewhere increase their battery by a little bit! :D
