Made the switch from the Galaxy Note to the LG G2, and still trying to figure out a couple things that bug me.
On my Note I could put the phone in my desktop dock and it would launch my alarm clock app (Alarm Clock Plus), and the clock would stay on all night. The screen would not time out while in this mode. Otherwise it would time out after a certain amount of inactivity.
On the G2 there is a display setting for how long the screen should stay on, but it seems like it is all or nothing. I want to the phone screen to turn off automatically after a minute of inactivity, but I want the screen to stay on when alarm clock plus is running.
The only way I have found to do this so far is using Tasker and Secure Settings to launch a configuration task "Keep Display On: AC, USB". Of course I am rooted.
Is there some other way to do this?
Developer options. Stay Awake. But weekday your looking for its daydream...look it up. I don't know how to set it up on LG g2

I'm curious what wifi setting people are using with the new 3.1 update?
Off with screen off
Always on
Always on while charging

Off with screen off.
Get tired of notification sounds when not using it.
Also, battery life seems even better with 3.1 - now regularly getting 12 hours per charge.
I have it always on. It doesn't really use much more battery and I like to have IM applications on most of the time. I just tap on the clock on the bottom-right corner and turn airplane mode on when I'm sleeping and turn it off when I awake. Simple and efficient.
Also "always on". WiFi used almost exactly 1% battery life per hour when I left my tablet alone for two days, not going to worry about a 4day "standby" timer
I'm on CM7.1 stable. Haven't had battery issues for a while, but starting a few days ago I've been getting rapid drain with heating. Battery use screen shows that the phone is awake most of the time the screen is off, but it doesn't reveal which app keeps waking it up. I also tried Spare Parts to see if any app is hogging the partial wake lock, but nothing seems to account for it.
Any other ideas on how to trace it? Must've been an app that updated in the past 3-4 days.

Just to show how this looks, here is a screenshot of the battery screen.
Notice that I put the phone in airplane mode for the past hour as I was writing an exam, yet it still appears awake with screen off. The phone was warm when I retrieved it after an hour of the radios being off! Something is seriously wrong here.

I can only guess it is an application or service keeping your phone from going to deep sleep- also known as "partial wake lock" or something like that...
What to do? You can probably nail the culprit using some application like BetterBatteryStats (Market it, or look for it at xda's app thread- it is somewhere here). It will help you find who/what is keeping the phone awake.
I think that Battery Monitor Widget can also give you similar info.
You may need some help in the BBS thread to help you interpret the results as they are not always obvious or easy to tell who's the problem.
Right. What's confusing me is that nothing in the partial wake lock list is showing more than about 10 minutes of lock time, yet the phone gets stuck awake for more than a solid hour of screen off time.

I think I figured it out. I had a trigger set up in Tasker that resets the phone's data connection every time it crashes out with an error (and my carrier WIND Mobile does this quite frequently). On days when the battery was constantly draining, it may have been because the network was particularly error-prone and my trigger therefore kept going off. And each time it went off, Tasker must have flipped the phone into awake mode.
I've turned off the trigger for now, to see if it stops draining.
I wanted to see how much screen on time I could get on the stock battery, and was surprised that I could get 12 hours.
I call bluff. Even though your showing screenshots. That would be incredible if true though.

I can see this as being possible if:
-You're sitting next to the router and/or in airplane mode.
-screen brightness turned all the way down + screen filter
-no app syncing whatsoever
-doing something that doesn't involve the network, eg: playing a video.
Shenanigans!!!

Exactly. I've seen them upwards of 6 hours when on network. But, not with him showing poor LTE coverage. No way that one will get 12 hours of on screen time.
It happens to me yesterday, I leave the phone in Airplane Mode at 11pm and in the next day I heard a low battery warning..and then I thought "ugh..bad kernel! it supposed to last than a day in airplane mode" but when I see battery status, it's been awake 10 hrs with 8h 26m screen on..idk if it's a bug or the screen really turned on because i'm using a cover (it's a Galaxy Note btw, forgot to mention)

Any chance we could see the detailed graph info (when you tap on the graph in the second screenshot)? Otherwise, I'll assume you were in airplane mode until just before taking the screenshots.
I was extremely impressed when I saw over 4 and a half hours of screen on time, since my OG Evo only got about 2 and a half (I think it got up to 3 hours once). Now that I've had the phone for a week, my normal screen on time is between 5.5 and 6.5 hours. That's with almost-exclusively using Wifi with good signal and screen brightness at 26%, no GPS, etc. If anyone can actually get significantly more than 6.5 hours screen on time without airplane mode, I'd like to hear how.
Sorry for the confusion, I was testing out "picture frame" mode here is what I did:
-I turned off the radios using the "phone info" app, which is similar to airplane mode.
-Screen brightness to min.
-Turned on all power saving options.
-Used "screen on" app to keep the screen on.
-Used the gallery with a pitch black picture(I didn't want to get screen burn in)
-The radio was turned on just prior to the screen shot so that I could e-mail myself the screen shot.

So 12 hours without looking for/maintaining a radio signal and showing a black screen? Not impressed.
I am using Cyanogenmod on Nexus 4 to perform some current measurements.
Now I have one problem where Nexus 4 will go to sleep whenever I disconnect USB cable (with screen turned off). The idle current goes down to almost zero (from 0.10A) and anything that I started to execute over adb finishes only when I turn on the screen or connect USB back to Nexus 4.
Does anyone know how I can fix this and force Nexus 4 to stay awake when I turn off the screen?
Anyone? Is there some settings in Android/Cyanogenmod that I can set?
Play a tune or something.
Or I bet there's an app in the app store.

Try SafeCharge application and there is a setting to keep a wakelock manually so that the phone won't sleep with screen off

Thanks. That's pretty much how I solved my problem.
I downloaded app that enables wake lock. Before device would always go into standby mode and lock everything up.
The idle current was pretty low with wake lock enabled (like 22mA)... not sure if this is normal.
Noticed in battery settings that my Wifi turns on and off frequently even when my device is sleeping. Doesn't seem to be affecting battery life but I'm wondering why it does this. It happens on both my Nexus 7 (stock rooted) and my Nook HD+ (CM11). I do have the "always scan for networks" settings off.
Attached screenshot is after I didn't really use my Nexus 7 for about a week.
I would imagine this is caused by certain apps requesting data. For example, your Gmail app may be set to refresh every one hour, which means it needs to use the WiFi to search for new data and download it, if needed. Other apps are similar to that as well, depending on your settings.
If it really miffs you, you can always use tasker and create a task that shuts the wifi (I have it put it in airplane mode since it does several things in one shot) off when the display goes off and back on when display comes back on...will need to be rooted.
