1. To start with, lets get to the list of bloatwares that can be safely disabled.

If any of you own the AT&T version, here's a list you can disable:-

AT&T Apps:-

AT&T FamilyMap

AT&T Hot Spots

AT&T Live

AT&T Locker

AT&T Mail

AT&T Mobile Locate

AT&T Mobile Transfer

AT&T Navigator

AT&T Ready2Go

AT&T Smart Wi-Fi

Drive Mode

Caller Name ID

Mobile TV

Plenti

Smart Limits

Yp (Yellow Pages)

Other Apps:-

S Voice

Amazon (I prefer the playstore version for frequent updates)

Amazon Kindle

Device Help

Live Weather (Yahoo)

Lookout

Theme Store

Visual Voicemail

2. Refrain from using any free application that has embedded advertisements. They tend to run threads in background to load adds and thus degrade the app performance and used data (so naturally consume more power too). Either buy add-free version or find an alternate app for same purpose and without adds.

3. Disable notifications from social media/news apps like Facebook, Twitter, Tapatalk, etc. Although, the phone wouldn't be that smart if all the notifications are disabled, however, keep them at bare minimum. Not everybody would be interested in notifications from all the apps, so spend some time analyzing through all the installed apps and their settings to turn off the notifications for the apps you do not need to get notifications for. There are several apps that keep sending notifications and running a thread in background which again checks internet to load the notification content. An example would be games like Candy Crush or Clash Of Clans.

4. Turn off "Send Usage Statistics" or "Help Improve the app performance", "Participate in improvement" etc settings from the app which sends data from your device from time to time which acts as a survey to improve the performance of the app. Although this is a necessary option for a developer, however, if you do not care about your granular contribution towards further development of the app, try deselecting such options while setting up new apps.

5. Refrain from using external Memory Management Apps and RAM Cleaners. They tend to run heavy background services to detect memory usage and kill applications. Trust me, you would be better without them.

6. Try using black wallpaper and lock screen. Also, always select Dark Mode if any app has theme section. This makes the pixels produce less brightness and considerably save more battery.

7. Keep GPS Location off when not using any navigational/location based apps. When the GPS is ON, there are some apps that tend to acquire a GPS Lock even though they can work without it. Keeping GPS Off will not allow such apps to request for GPS Lock. GPS Locking is a battery draining process.

8. You can use certain tools like Greenify, WiFi Automatic, etc. to automatically manage application states or phone wireless to save some additional battery. Use these only if you are lazy like me. Otherwise you can always manually turn on/off wifi/bluetooth/nfc etc etc. Also, there are tools (like Juice Defender) which can enable/disable data connective at a frequent interval which results in really good power conservation without loosing push notification.

With applying most of these settings, I'm getting 6-7 hrs of screen on time very easily even when I've downloaded 1+ GB data and 40 minutes of video chat (hangout). Not to mention the usual gaming and application usage.:cyclops:

I hope that helps. I'll keep adding if I get any (without root).
