[TIPS] [BATTERY] Share your juice-saving tips - G2 General

Our G2 is a battery beast already, but a lot of people are still looking for that extra sip that'll help the phone make it through more time in the hand and less hooked up to the wall.
And there are definitely many ways to do just that.
THE LIST IS AT THE BOTTOM OF THIS POST, GIVING LINKS TO THE POSTS CONTAINING THE TIPS. NO NEED TO SEARCH THE THREAD (if I do my job correctly...)​
---
There are many topics around battery life like this one which is very rich but nothing that consolidates those advices for a simple search.
I propose to maintain a catalog of tips on this OP, and simply link to the post containing the tip.
A tip will be added to the OP if it's confirmed by multiple users (either through replies or through thanks)
---
Now let's put some ground rules for sharing our tips:
The objective is that the tip can be applied easily, based on the sole post that contains the tip. You need to edit it if necessary, a tip is worthless if one has to read through 2 pages to figure it out.
*
THE DON'Ts
- Tip must NOT be "install this ROM/kernel it's much better".
- No battery-life bragging: No screenshot of your awesome battery life, let your tip speak for itself when we apply it.
THE DOs
- Tip is specific (specific setting, app setting, freezing a particularly useless and battery consuming app,... )
- Tip can require to be rooted but must be clearly indicated
- Tip can be a kernel setup (governor/scheduler, underclocking,...) but you have to be very clear on how to set it up (which kernel tweaker app you use for instance)
- As much as possible, provide screenshots of the target setup
- It is better to update your tip (especially for kernel settings) rather than posting a new one for the same thing.
*
Preferably, use the following template for your tip:
Use the following for your post's subject:
[AOSP/STOCK/ALL][ROOTED/NON-ROOTED][APP NAME/KERNEL SETTINGS/ROM SETTINGS] Short description of the tip
In the details, the following info will be appreciated:
Detailed procedure to apply the tip
Explanation of why it's saving battery
Known disadvantage(s)/limitations
Screenshots

I'll provide a couple of examples below.
I hope you fellow G2 users like this idea!

THE BATTERY-SAVING TIPS
Generic tips (rom settings, kernel settings,...)
ALL ROMS
[ALL][NON-ROOTED][ROM SETTINGS] Deactivate "Allow Wi-Fi scanning"
[ALL][NON-ROOTED][ROM SETTINGS] Adjust auto-brightness level
[ALL][NON-ROOTED][ROM SETTINGS] Check your Fast Dormancy setup (RILJ and DataTracker-FD wakelocks) /!\Carrier-dependant/!\ also on this post with additional info
[ALL][NON-ROOTED][ROM SETTINGS] Disable/reduce window/app animations​
LG-BASED (STOCK) ROMS ONLY
[STOCK][NON-ROOTED][ROM SETTINGS] Disable unused stock apps also on this thread with many suggestions for apps to disable
[STOCK][NON-ROOTED][ROM SETTINGS] Disable Knock-On (external thread)​
AOSP/CM-BASED ROMS ONLY
App-specific tips
[ALL][NON-ROOTED][GOOGLE SEARCH] Deactivate the "OK Google" detection from any screen
[ALL][NON-ROOTED][GOOGLE SEARCH] Deactivate location reporting / history (NlpWakeLock and NlpCollectorWakeLock wakelocks)
[ALL][NON-ROOTED][FACEBOOK] increase the refresh interval
[ALL][NON-ROOTED][LUX] Use Lux app to improve auto-brightness​

---

[ALL][NON-ROOTED][ROM SETTINGS] Deactivate "Allow Wi-Fi scanning"
*
In the Wifi connections screen, open the "Advanced Wi-Fi" from the menu
Uncheck "Allow Wi-Fi scanning"
This will prevent the location services (whether google or else) from scanning for wifi network for improved location accuracy when Wi-Fi is OFF. I have seen no degradation in the functionality of Aviate, Tasker and Google Now with that option deactivated however it does save a lot of wakelocks (wlan_rx_wake). This will not change the Nlp*WakeLock though.
*
This is mostly for people living in metro areas where cell coverage is dense and sufficient to have a decent location out of cell towers only.

[ALL][NON-ROOTED][GOOGLE SEARCH] Deactivate the "OK Google" detection from any screen
*
With its last update Google Search allows the "OK Google" detection from any screen. This is a battery sucker.
*
Open Google Search
Open the settings from the menu
Go to Voice > "Ok Google Detection" > Uncheck "From any screen"
*
This will prevent the AudioIn wakelock which can be significant and that not everyone might need (I for one use a search button on the navbar which opens Google Now voice input when long-pressed, the effect is strictly the same)

---

[ALL][NON-ROOTED][FACEBOOK] increase the refresh interval
Most people could probably live with auto-refresh of their Facebook happening less often.
Head to the settings of the app and increase your refresh interval. That's a little bit less waking up the device and using the data connection.

---

[ALL][NON-ROOTED][ROM SETTING/LUX]
Set custom automatic brightness curves using the Lux app (app store). Link desired brightness levels directly to the device's light sensor readings.
Default auto brightness settings in LG's ROM are finicky and depending on your preferences, you may be able to live with a darker screen.
Lux tutorial and setup should guild you through setting custom curves. Additionally, you can allow other apps to over-ride the Lux settings, for example, if you turn on LG's battery saver function and force the brightness automatically to a very low %.
Disadvantage is the need to keep the persistent icon to prevent the app from being killed. Increasing the priority when rooted can help, but it still seems to be occasionally killed.

---

[STOCK][NON-ROOTED][ROM SETTINGS] Tune down the brightness in auto mode
Auto-brightness can be adjusted, that is when active, use the slider to have an overall brighter/darker screen. The slider is not just for manual adjustment.
No downside on this one

---

[ALL][NON-ROOTED][GOOGLE SEARCH] Deactivate location reporting / history
This one is a big battery sucker, although it seems that it's more noticeable when running Dalvik runtime than ART.
What Reporting does is periodically polling your location so Google Now will be location-aware and provide you local suggestions, travel time to your home,...
History, on the other side, will save these location reports and allow Google to build your location profile (most visited places typically) and for instance let you know ahead of time when it's time to leave for work depending on the traffic or transit status.
Now, if you don't care for these location aware suggestions and/or your concerned about your privacy, turn these suckers off.
This will typically affect the wakelocks "NlpWakeLock" and "NlpCollectorWakeLock" which should go down dramatically unless you have other location-aware apps.
Open Google Settings, under location turn off both reporting and history. You will save a significant amount of juice.
Obviously the downside is limiting Google Now functionalities but those not depending on the history will be available "on demand", that is when you open Google Search (the location will be determined then only and you'll get your suggestions, instead of these happening in the background)

[STOCK][NON-ROOTED][ROM SETTINGS] Disable unused stock apps
This one will be a try-and-see. I for one don't use smartshare at all.
And it has happened that I'd have that Smartshare.MediaServer going all crazy and sucking up to 15% of my battery for no apparent reason.
So I disable it and if it doesn't really save a lot of battery on a day-to-day basis, I'd say it can't hurt anyway.
People may want to do that using Titanium or ROMToolbox, I guess that is a personal choice.
If you experience any sort of issue (haven't myself) then simply re-enable it.

I got a thread on this in my signature. Some thing are general, other things are more specific. If you choose to use any, feel free to do so.

I'll definitely try these out and include them!

Since @vPro97 got the wakelock covered i guess ill just delete my part in all of this ?

---

Thanks for that. The FD is included in the previous post (not mine) but I haven't had the time to update the op yet. I need to figure out which carriers have are applicable for the FD tip though
However I did a not of research on the fast dormancy and it seems that if you enable it on a carrier that does not support it then it's a battery killer. By default it is NOT activated unless your carrier did activate it in which case it's likely that it does support it.
If not activated then it simply does not save battery as it could if your carrier supports it.
That is, at least, my understanding

---

Thats correct @AnteusFogg.. in my situation every rom i flash, i end up with a FD status unknown and have to manually switch it off for the wakelock to disappear on my phone/operator...
I guess those tips will make for an excellent sticky thread with more to come and an organized OP for the new users

Can you give the name of the wakelock for my reference?
I'll update the op tonight.
Also, feel free to give advices on how to organize the op for easy reading

Which apps in particular? Can you please put up a list or a screenshot of the disabled apps in your post? (ideally edit your original post rather than posting a new one)

Mind updating your post on top of this page so I have only one post to reference on the OP?
Thanks!

[ALL][NON-ROOTED][ANIMATION SPEED]
If you want your phone snappier and using less battery you can easily try reducing the amount of time allowed for the animations. Just enable the Developer Options, scroll down and reduce or even disable the animations. If you multitask and need allot of Screen On Time, this tip can save you plenty of juice.
See the pic below.

Never thought of that as a battery saver... It does make the phone feel snappier but battery saving really? Did you observe a noticeable improvement?
