Here is a guide on how to prolong battery life of the G2. Some tips are general for all device, while others are more specific.

1. Disable bloat

What one would perceive as bloat varies from person to person. On my D802 I've disabled the following.

Chrome
Google Play Books
Google Play Magazines
Google Play Games
Google Search
Google+
Hangouts
LG GNSS
Life Suare
Life Square Log Manager
Slide aside
Voice Mate
VuTalk


IcemanF-22 has made a list for LS980 (Sprint version) (CREDIT GOES TO HIM/HER). His/her list is more thorough but some stuff are carrier specific and not available on the Open D802.

2. The Hidden Menu

There are a number of tweaks that can be done in the hidden menu. DISCLAIMER: I am not responsible for anything you do to your device. The hidden menu is hidden for obvious reasons!

To enter it, type one of the following codes in the dialer:

3845#*801# (for T-Mobile variants)
3845#*803# (for AT&T and Canadian variants)
3845#*802# (for European variants)
3845#*800# (for At&T model)

The tweaks you can do here, are amongst others, changing Fast Dormancy mode and disabling LG MLT. You can also disable Temperature throttling which fixes camera lag and fixes lags in general but I would not recommend it. LG left it off for a reason, don't you think?.

What is Fast Dormancy mode? Read more about it here: http://www.androidnz.net/2012/06/at-...able-fast.html
Basically if your carrier doesn't have it and your phone has it enabled, an unnecessary drain will occur (sometimes even keeping the phone awake which can be seen as wakelocks). If you have disabled it but your carrier has it on their network a battery drain will also occur, therefore consult your carrier whether they support Fast Dormancy Mode or not.

By default, it was "unknown" on my D802.
I disabled it by going into the hidden menu as stated above, and go into settings > FastDormancy. There you can change it to either Enabled or Disabled in accordance with the settings of your carrier.

- LG MLT
In the hidden menu, scroll down to LG MLT. Disable it by unchecking the "Enable" box. Reboot your device.
You will notice that you have more free ram and battery life will be improved a bit.

3. Disable Knock-on
This is the sad truth - one of the most beloved features of the phone is to double tap to wake it. But when you need more juice, it can be a good idea to disable it as it usually accounts for 7-10% of the battery drain. It's not a big deal if you are home or have a charger within reach, but disabling this awesome feature can actually give you about 1 hour extra of screen on time and the idle drain is noticable lower.

Disable this by going into settings > general > gestures and disable it by unchecking the box.

4. Force close Android system (may/may not work)

This tip is not widely known and doesn't work for everybody, but force closing the android system after each reboot can make the Android System consumption a good bit smaller. Do this by going into settings > general > apps > all > android system > force close. It will start up immediately after and it will not harm your phone.

5. Kill'em wakelocks!
Quote:

I don't know who you are. But I will find you. And I will kill you.

To find those pesky apps keeping your phone awake, download Better Battery Stats from here: http://forum.xda-developers.com/show....php?t=1179809
And either GSam Battery Monitor from Google Play or Wakelock Detector from Google Play. It will show you what apps have been keeping your phone awake when you put it to sleep.

6. Disable location services from Google
To disable this, do the following: Apps > Google Settings > Location > uncheck Access location
You can also disable Android Device Manager for a bit extra juice.

7. Auto-sync only what you really, really need

Auto-Sync kills battery. Period. Make up your mind, do you really have to be notified whenever an email arrives, or can you wait until you have time to check for new e-mails? If you can, you can also save a bit of battery. Facebook, WhatsApp, Viber and other apps that require you to be online at all times do kill battery as well. It can be managed a bit by installing

8. 2x Battery
Intelligently manages your internet connection by disabling it after you lock your device, and enables it for 2 minutes every 15 minutes to check for new messages and so on. The only downside is that there will be a delay receiving whatsapps and viber calls. This can be disabled easily if you are waiting for someone to call/message you. The app can be found on Google Play. I personally found a negligible increase in battery life using the application.

9. Remove Rogue Apps
Believe it or not - some apps can cause a battery drain even if you don't use them at all! Make sure you delete the apps you no longer use and if you notice a decrease in battery life after installing an app, try uninstalling it and see if the battery life is better.

A Note about Wakelock Detectors and Better Battery Stats in 4.4.2 KitKat

Chances are you have updated to 4.4 kitkat by now. The problem with KitKat is, that you are no longer able to see the details about what is draining your battery. Therefore you need to manually check for rogue apps (and that may occasionally require you to delete apps you like) and find better alternatives.



CarrierIQ - US CARRIERS ONLY

Want your carrier to earn money selling information about you? No, do you?

To disable this, do the following (Credits go to burningembers):

Install System Tuner from Google Play store.

Click the red System Android, click Android System, Details, then uncheck all 7 CarrierIQ related processes.

This list is not complete. If you have any additions, please post them here and I will update this thread!

I do personally have a stock, unrooted D802, but I've heard people having success in disabling CIQ that way. Would be awesome if someone could test it In the thread where I found the guidelines people seemed to be able to do it.

3845#*801# is the code, right? Which carrier are you on? I see you are running CM11 on your G2 in your signature. This is only for stock

Oh, If I go back to stock and disable mlt, would it stay disabled once I flash back?
