I would like to get some more information on the WiFi battery drain problem after the .21 update. Some users report decreased bat life due to WiFi, some see no differences. Would be interesting to see what the magnitude of that problem is.
My WiFi performance is increased by at least one bar, but battery life is decreased to 6h screentime...
My battery drain is massive after the .21 update, and 100% down to the Wifi (in battery stats)
They have obviously turned up the power but i cant say as ive noticed a massive difference with performance.
Yesterday i lost nearly 20% battery in the space of 30 - 45 mins.
I mentioned it in another thread. Support told me that there is an update on its way. Whether it will solve this issue or not, he couldn't say.
Yes, Gary updated one of his other threads, we have an update literally just around the corner. Also we may actually gain use of nvflash!
Anyway, back on topic, yes I've seen some increase in battery consumption, but I don't think it's as bad as some of y'all. I can leave my WiFi on 24/7 and still use my tablet for at least 3 days.

What makes you say we may gain NVFlash access ?
Had my prime hooked to my TV going through tobuscus's videos on youtube while I was gaming yesterday. Went from 100% to about 30% after ~5 hours. Not bad especially streaming 720 videos

There definitely is increase in battery drain since .21
To say it's the wifi, i dunno...
Yes. the wifi, according to the stats, is the biggest battery drain, but seeing as we haven't had these battery stats previously, we can't really make a comparison on that.
For me i don't see much difference between wifi on or off.

4/27/2012 Update -
We are still validating a new firmware release. We are also tracking user reported issues with Tegra 3 games, WiFi Direct and some continued random reboot/lock problems with a few units. Based on current regression testing at HQ, NVIDIA and Google it appears we will need to sway out a few units to pinpoint exact user problems. For the unlocked audience, we have requested a version of NVFlash that works properly for users who unlocked their units.

From Gary himself.
Wifi was definitely affecting me. Bat life was dropping really fast. I now have wifi off when on sleep and the battery literally lasts forever. Been playing road warrior for a couple of hours each night some web browsing and you tube playback oh and messing with the ui. I still have 71% battery after 3 nights. Dock not even plugged in. Drops maybe 1% over an 8 hour night if that now. Was about 10% with wifi on.
Oh and when using its in performance mode, switch to power save before sleep.

First thing I noticed after the .21 update was the battery drain not an improved wifi signal. Factory reset mine. Same deal, now I just keep it in the dock while I'm out on the road.
I actually see fastest battery drain using the dock. NvFlash would definitely influence me to unlock my tab but def not before I know it works for most bricks.
I'm on a .21 ROM and my battery life is awful. I lose about 30% overnight while it's sleeping.

that's crazy..lol i may lose 2% overnight and i leave wifi on 24/7. im also on latest .21 firmware.
you have something else going on in the background to drain that much. i never heard of such battery loss while a device is only sleeping overnight. You better get the app here in xda called "better battery stats" to see what's really draining your battery. seriously doubt its wifi alone doing that.

I have "better battery stats" and it clearly shows that most of the drain is due to WiFi. There is a handful wifi processes which draw power.
I also recognised something else. Over the weekand I stayed with a friend. The battery drain on Wifi was back to normal over the weekend. Back at home WiFi sucks battery again.
I assume the Prime-Router type must have something to do with it.
I have a WRT350N at home.

Batterydrain and charging issue!!
I'm also one of those whose had a flawless Prime until the .21 update.
After the update I almost immediately experienced one "Sleep of Death"
that a soft reset fixed and that has actually not occured again.
Two other things are killing me though, after the update and the "SoD"-
incident I have terrible battery time and the tablet will only charge via
the keyboard-dock. If I insert the charging-cable to the prime itselves
it recognizes the cable and the charge indicator lights up red but I don't
get the lightning symbol on the battery status and in settings it says it
is not charging. If I put it to sleep for a while and wake it up again I get
the lightning in the battery icon and it says charging in settings, but it
charges so slowly I recon it would take 3 days to charge to 100%
I have RMA'd it one time but the useless guys who had it for 14 days just
changed the USB-cable and said it was A-OK, still nothing had changed.
Don't want to send it back in, tips and tricks would be much appreciated.
Thanks

that doesnt show anything. Wifi and display will always be the biggest battery drainers. plus the battery reporting inside prime is flawed. you need an app like better battery stats to show you whats really going on. my prime shows the same thing, as wifi being biggest drainer but i still get great battery life. from what you reported earlier, something else is going on in your prime you not aware of to lose 30% overnight with prime just sleeping.
I think I was one of the first to notice & question the battery drain after .21 update. Mine isn't as excessive as some are reporting, but it is definitely noticeable.
For example, before the .21 update... during sleep/overnight.. with WIFI never turned off, I will see perhaps 2% decrease in battery at most.
However, with .21 update... during sleep/overnight, Prime will lose about 8 to 10% in battery %. So, it is about 6 to 8% hike in battery drain during "sleep" stage.
I haven't tested or examined the battery life difference when it is being used.. as that's a bit more difficult to gather data based on my use...

i think you was. Its so hard to gauge and compare everyone's battery usage. Everyone has different settings used and different usage. I heard one rumor of Asus possibly increasing the wifi power for better connection/range. It was never confirmed nor denied. I never mentioned this issue before. I can try to dig up info on it from Gary and see what i find out. We have an update due to come out any moment now so we all need to see how battery performance is after that. I'll see what i can find out. Asus has been having trouble recreating the issues alot have reported. which makes it hard for them to fix if all their units they test never show the symptoms. For other software related issues, more logcats may need to be done and sent to asus. for ex. they haven't really been able to recreate the games crashing/freezing issue. Same with wfi direct. all their test units seem to work fine...lmfao new update is supposed to address some of these issues and more.

Eh, really? Wifi direct is completely worthless/useless to me atm (as in, doesn't work).... and to those who actually got it to work (based on their comment), it seems half-assed integration. Wish I have one of their Test Unit... seems/sounds perfectly functional (void of any of the issues/problems....).
Btw, don't take offense to this... but I have to ask...
1. Are you the unofficial spokesperson for Asus now? It still amazes me how they continue to respond to you & yet, I keep reading those with "issues" are yet to be contacted.
2. Did you have the authority to release/leak GPS dongle information? Such as leaking the photo a day before to Land of Droid for your 15 min. of fame.

My prime was largely fixed with the latest update (.13).
BT/Wifi: fixed.
Random reboots: fixed (although mine were very infrequent to begin with).
However, now I would characterize the sleep battery drain to be at least double, if not more, than it was with the previous update.
Is this affecting all primes? In 8 hours, I am loosing 30-40% charge while the unit is asleep and off the charger, vs. perhaps 10%, at most, previously.
Yes, some will say it isn't but they just don't realize it.
I left the house this morning with a full charge. I just came out of sleep for the first time today and I'm at 97% so no I don't have the new battery discharge while sleeping feature. I have had 3 unexplained shutdowns since the .13 update where I didn't have that on .11
After .13 update it also took me a while to realize that I was getting "sleep of death" characterized by reboot and battery drain after the prime is put into sleep mode.
I was able to confirm it because I have GoLauncherEX installed and after a reboot, it asks me to choose my home screen. I noticed everytime after I woke my prime up, I would be asked with the choice, indicating that it rebooted. However, since I kept it plugged into the charger, I didn't notice battery drain until I read the forums.
I think in the older versions of ICS wifi was turned off in sleep mode now it's on all the time by default. I changed mine to shut off while sleeping and set it so my e-mail only logged in when I want to check it.
Since the update I've not noticed any significant performance improvements or issues. My Prime will go hours with minimal battery loss when sleeping, has never had the "sleep of death" issue, and does not seem to have significantly better Wi-Fi performance.
I've not had the problems that others on this forum indicate, though. I've been quite satisfied with my Prime.
My prime has the sleep shutdown issues from the .13 update but I have no battery issues. I found out that manually turning off wifi before I stop using my tablet is temping prevent the sleep death issue, and last night it stayed on all night which was about 8 hours and the battery barely went down at all. I actually looked at the battery graph and kinda laughed at how straight the line was since the battery barely changed. It must have went down like 1%.

How can something be wrong with an imaginary device?
Example of battery drain while sleeping.
I have eliminated as much as I could from running while sleeping. I have been watching over the last 4 days and you can see when my tabs screen is off the battery is draining. I used to brag to people how well the battery is when your not using it......I used to get almost a flatline.......with maybe 1 to 3% drop while sleeping. You can see that is not the case sense the .13 update. You can also see something is keeping it awake. This was never the case before the update. I will keep looking for whats causing the tab not to sleep.......

Do not know what u talking about. I said I get great battery life n posted results in other thread
Add me, too to the list of those whose Prime was working great before the update, and now is completely drained dry if not plugged in overnight. I use to get 2 1/2 to 4 days or so of modest use. Now I lose all power overnight, every night.
I hope a fix is on the way.
I havent noticed anything too different for battery drain.
Charged it this morning , 4h, 23minutes ago and its at 97%
It's really an issue, I left my Prime idle all day with the dock attachment, and the dock battery is drained completely after 15 hours. It didn't have this issue until the .13 update.
I wish Asus would just give us back our .11 FW while they work on the issue. It's the least they can do at this point.
My prime has been off charger and on standby for the past 3 hours... unlocked it and...
Dock is 100%, TFP is 99%.
Boom.

You don't know if the update is the real issue.
It could be just like how people thought the update broke the YouTube app (it didn't). It could be very well something else, especially since there are many that don't have the issue, myself included.
I forgotten my Prime over at my sister's house this passed weekend, it was nearly fully charged when I last used it to output Youtube to their TV over HDMI. I'm going to pick it up today and I'll know for sure if this is a problem.

There is zero doubt in my mind that the update is the cause of the issue. This situation is nothing like the Youtube issue (i.e., there's no equivalent of a "server side" problem for the battery drain many of us have experience immediately following the update). Not to mention that the update changed the usage of the cores and raised the minimum clock frequency.
Not having any sleep issues after update. Charged up and unplugged Friday evening and put back on charger earlier today. Pretty much the same as before update
Ill start with the obvious. Screen not sleeping while charging is disabled. System performance is set to Power Save.
For testing I charged my dock and tablet to 100%. Before sleeping I unplugged my tab/dock from the charger and locked/turned off the screen and left it on my desk.
I awoke 10 hours later to a completely dead dock and completely dead tablet. Before my tab/doc were able to standby for several days.
My apps have not changed other then updates from the market. I have also restored my apps from Titanium Backup and blocked the app updates with the same battery loss.
I am going to try to roll back to .11. Once successful I will post new test results.
Also just for point of note, I have never once had a forced reboot on this prime. Wifi works decent with BT disabled as described by others. GPS is fail.
This is just ridiculous... All I've been doing is browsing xda... everything else is turned off.

I know the screen is turned up, but thats no excuse, my tf101 manages at least 6 hours at the same brightness.
What the hell is going on - where is that improved battery life I purchased?
Something else is the issue. That is very uncommon. No reason it should've drained that much. Even if it is a new device needing battery to go thru more cycles. I'd say try a reset. Maybe your battery meter reporting false info. No way balanced with super ips mode would drain that much just browsing the web. Unless you have some app or widget that draining like crazy. How long have you had this device? What was the last apps or Widgets you downloaded?
Surfing the web does drain the battery the fastest next to display. Plus watching flash videos is a major battery drainer. I'd say check for rogue apps. You can also download better battery stats to see what has really nbeen draining battery the most. I easily get 9-11 hrs of battery on balanced mode doing more than you did.
First of all, the TF101 does NOT have the same screen brightness as the TF201.
http://www.notebookcheck.net/Review-Asus-Eee-Pad-Transformer-TF101-Tablet-MID.54258.0.html
http://www.notebookcheck.net/Review-Asus-Eee-Pad-Transformer-Prime-TF201-Tablet-MID.69849.0.html
Average screen brightness of the TF101 is 331.6 cd/m^2 and the TF201 is 484cd/m^2. It's almost FIFTY percent brighter at maximum brightness than the TF101.
The TF201 at 50% brightness has a cd/m^2 average of 305. When Super IPS+ mode is used a maximum average of 514 cd/m^2 is possible.
I'm not interested in a reset at this point, but I am going to download a battery analysis tool because this is crazy.
The last apps I downloaded were an irc client and a like 2 games.
The battery life has never been fantastic - but this is just bad. I've had it about 10 days now... gamestop unit so no returns.
There was no flash, no sound, just web and nothing more.

Your telling me.. I have them right next to each other and there's no noticeable difference between the two...
On .15, I've been running about 15%/hour on heavy browsing, video, gaming (although heavy gaming can push 30%/hour), and about 7.5% on things like ebook reading, light browsing, etc. Standby has been about .375%/hour, which is excellent.
So, the OP's results are an anomaly, clearly. I'd say, do a complete shut down and then restart, and see what happens. Has to be some kind of rogue app or system component causing this.
GAmestop has a 30 day warranty exchange program. If you want you can easily exchange it for another if the battery life doesn't get better. What you reported is something unheard of before. Never heard a battery draining that fast. Better battery stats is the best for battery analysis.

An exchange may help - would be a pity though because I have working wifi and gps w/ 0 lightbleeds. I was considering virtuous, but i haven't unlocked the bootloader yet.
I honestly don't feel a factory reset would change much... maybe its just. 15.

Waiting for a complete discharge first - then I'll charge it up and see if this continues.
here's what bbs says so far if anyone is interested. I haven't updated Boat browser lately so I don't know why it wouldn't have done this before if that was the problem.
Battery still new if only 10 days old. Do the complete discharge like you said then charge up again. I don't think it really needs to be exchanged unless the poor battery life continues. Boat browser is your culprit. You could try switching to another browser. Boat browser might drain more power than others. Try ICS+ browser or opera mobile. I use those n get great battery life. Always make sure your apps are up to date. Updated ones more optimized.
I hope it's not boat D;

I really think you might have something else or a few things running in background you not seeing. Another way tl see is load up the Asus task manager widget. See if any odd apps or anything is running. If so, kill it. Also, make sure you put display to sleep at least 1 minute or less. I have mines set on 30 seconds or sometimes 15seconds. Which means if no activity detected in that time frame, screen will cut off. This can dramatically improve battery life. Also make sure to cut down the frequency of notifications. I have my mail set to 1hr. Which is the Max or longest interval. Or you could cut it off and have it update manually when you open mail up. Also check to make sure you don't have apps that syncing too often. Like Facebook, etc... this can be found in settings. I city my Facebook notifications off. It goes off too much. So instead it'll update whenever I open up the app. Lots of things you can do and check to optimize battery performance. Also live wallpapers can drain. I don't use them. Then its best to leave auto brightness off. Better battery life can be had using manual. Plus even if ips+ is off but still on Max brightness, it'll drain battery fast. I never have my display more then 25% with ips+ off. One thing you can try is to put brightness all the way down. Then cut on ips+. The display is bright n will drain less than cutting brightness all the way up. Someone posted good battery life with that setup. I'm still testing it out.

Will 1 hr notifications affect google voice notifications as well?
Not sure. Don't think so. I think you can set Google voice notifications frequency within the app itself.
Still getting the exact same results 1 hour and 40 mins into a fresh recharge.
I uninstalled boat browser and reverted to stock - stock is draining at the same rate.
I want to try a factory reset - but I really don't want to have to install everything and get it configured right again :/
considering unlocking the bootloader so I can make a nandroid backup - but its risky if its a battery problem instead of a software one.
I ended up getting 5 hours and 6 mins total yesterday after switching power saving halfway throufh and cutting the brightness 30%.
Don't risk warranty unlocking. I honestly don't know why you getting subpar battery performance. Most seem to gget great battery performance. Try a factory reset through settings or stock recovery mode. So it can clear all old data or any bugs might be prevalent.

I'll give it a shot tomorrow night when I get home from college. I installed juice defender ultimate so I'll give that a go in the meantime.
if I factory reset I'm probably going to revert to honeycomb with stock firmware because I have a gut feeling its .15 and ics is only hindering some of my apps from working at the cost of a nicer ui.
As I said I have working gps/wifi so the firmware updates aren't doing me any favors.

I have mines set to always n still get really good battery life.
Op, I heard apps like juice defender n such don't really do much for tablets n may actually cause more battery drain. Reason because depending on your settings in that app, it'll constantly be trying to kill or shut down processes that'll pop right back up. Plus killing of certain processes might cause issue or more CPU strain. It'll be better to just freeze them. Just something I read here on xda. I think of was in the tips & hints section of better battery stats. They said not to use apps like juice defender n such.
Just like the title says, after 5 hours of light usage my prime factor for battery drain is CellStandby at 42% (the phone itself was down to 70%).
Anyone experienced this so far? I'm aware that LTE is rather demanding but it can't be that bad vs HSPA which drained next to nothing on standby

It's a bug in the software.
Thanks, I did search (albeit quickly) in the forums here and didn't see any mention of it.
I did see an article about the international model being affected by a similar glitch so.. all models would have this ?
I've had the phone for 5 days and gone through maybe 8 batt cycles. I'm not getting more than 2hrs screen time on any cycle. This is stupidly horrible battery life. There has got to be something severely wrong. I don't do much with the phone. I can't even with less than 2hrs to work with. Overnight batt loss is maybe 8%.
Any help is ENORMOUSLY appreciated.

Thanks, I did search (albeit quickly) in the forums here and didn't see any mention of it.
I did see an article about the international model being affected by a similar glitch so.. all models would have this ?

I believe all have this bug. It's just that, a bug. And there is a fix, but I'm too lazy to apply it. (Assuming it works to fix the bug in the U.S. variant software)
I'm on HSPA with TMO but it seems to depend on reception more than anything in my experience. Here's my log from today:
Lol, sorry for the huge image
a bug as in it isnt actually draining the battery or it is really draining it?
I'm in the same boat, and there is no way that the standby is just a calculation error. If I sit and use my phone continuously after charging I can get 2 hrs of screen time while the battery drops from 100% to ~65%. During a normal day of light use I completely drain the battery and my screen time might be 1h50m at most. So something is definitely up - although I'm also getting terrible signal strength, and I think that might have something to do with it. I've searched every thread and have made sure that I have no rogue apps or processes consuming the battery either.

edited - I take it back, after restoring my phone last night I have gotten 2h25m screen time after 11h45m since charging and I'm at 17%. So, doing better but not great by any stretch.

I read that it is simply a graphical error. It should be reading 3.4mw but it's set to 34 so it's showing far more use than it really is

Hi guys
This seems to be an issue on all SGS3s. I have both the LTE and international model and they both show high cell standby. Check this thread out for more info on the i9300 forums to understand why its showing so high which is actually a calculation error
http://forum.xda-developers.com/showthread.php?t=1732722
My i747 is rooted so I decided to make a backup and flash the zip fix they provided and seemed to work. But the risk is inherently yours if you want to try it. Its just an xml file so I wasn't worried trying it in my case. I am more sending the link so you can see why it reports using so much battery
My cell standby battery usage went from over 50% to 5%
Basically, cell standby is not really killing your battery, it overestimates the power usage as being 10X more than what it is from my understanding

Yes yes yes! This is exactly my experience too! There must be something wrong if all others report 4+hrs screen time and we can barely break 2hrs. I'm in San francisco. My previous atrix "4g" would do at least 3hrs during my day to day.
Please, help. I'm really sad. Was really looking forward to at least an extra 30min over the atrix in my day to day.
So is the battery actually draining that fast with the cell stand by issue... Or us the battery actually higher charge than reporting?

Are exactly the same thing I'm also experiencing. I've come close to taking it back and exchanging it for another one but I'm not sure if this is how all of the US versions of the S3 are. Been reading through threads here and posted on a few of them and it looks like short battery life is a pretty common problem. I hope someone comes up with a fix pretty soon before I run out of time to exchange or return it.

You are close, but not exactly right.
When writing the software one of the developers entered 34mw for how much the battery should drain at standby instead of 3.4mw. A simple typo, but im sure if there isnt a fix already that there will be soon :]

There's a fix that's available on this forum but that only fixes the reporting. It doesn't fix the poor battery life.

Should we start a new thread? I've been posting in all the various battery threads to avoid getting yelled at for starting a poor battery issue thread. You're the fifth person to note the same issue. I too restored my phone this morning and it seems to be doing better, but still nowhere near what others are reporting. Also not nearly on par with my previous Atrix.
Maybe we have valid reason to start a new thread?
I applied the fix but still have poor battery life. Just as bad if not worse than my epic 4g.

CDMA people make sure you post your carrier when discussing battery life. GSM battery life for me hasn't been too bad. 10 hours constant use or so on wifi and around 6 hours or so on hspda. Standby time is very good. Especially for stock kernel.
I'm sure we can get some more once the LTE switch gets added.
That fix is just for the calculation of cell standby drain, not for how much it is actually taxing the battery. Several people on AT&T seem to have a real problem with excessive battery drain in standby, and (for me at least) it seems like it's happening when I have a poor signal. Unfortunately, that is mostly all of the time.
I found this old thread, and the APN listed there seems to help. It's just an interim solution though and I have to imagine AT&T will have a software fix for us soon.

Hello,
So i bought the G2 mini last week and i am a bit disappointed by the battery life. i can't go more than 4-5 hours of screen on time.
The problem ist that "Android OS" and "Android system" are each draining about 19-20% of the battery. Even after a factory recet it is the same.
On the phones i had before these two were about 10 % TOGETHER.
So does anyone know if it's normal?
Thanks in advance
I have same problem.
Did you tried to look what apps is draining your battery ?
It happens without any apps on the phone. Just after reset. So either it is normal or it is a bug on the phone. But i think it is getting better know. I can get average of 6 hours screen on now. But still not normal i think
I have a similar problem. Bought my G2 mini three weeks ago. Seemed good battery life to begin with. Now, intermittently, it's draining up to 2% an hour in idle (just syncing a not-much-used email account over wifi). It's Android OS which is using up the battery, not apps, according to Android's battery information. And it even did this a bit when I tried in safe mode. But sometimes it works great, with very low battery drain. I did a factory reset last night, and the battery drain has been only 3% in five hours. But I'm not sure I trust that it will stay this way. I have a week to decide whether to return it!
(This is the second problem I've had with the phone. Until a few days ago, it would be using 10-20Mb of data a day, which is a big deal when you have a 500Mb contract. Again, it was Android OS that was using up the vast bulk of this data, not me. This behaviour seems to have calmed down a bit in the last few days.)

If it is 4.4.2, then that could be the reason!
Google Built a Bug into 4.4.2!
Hmmmm. let's see on GSMArena. [LINK]
Oh, no! How Horrible!
---------- Post added at 15:32 ---------- Previous post was at 15:31 ----------
The Bug is: AndroidOS-Process eats up your battery.
Mine is 4.4.2.
What's the bug? I haven't been able to find anything about it. And I can't see anything on the GSM Arena page you linked to. Is it a general bug in 4.4.2, or specific to the G2 mini?
Thanks!

Battery drain is not for 3g or 4g power consumition. If 2400 mah die with 3g in three hours, what about moto g or other phones...
The problem is fast dormancy. I desactivate it. If you want i can make a tutorial.
With 100% 3g and fast dormancy battery last 12 hours with 1h 30 screen.
With 100% 3g without fast dormancy battery last 48 hs with 4h screen.
Oh rats, this is the 4.4.2 camera bug, isn't it? Only for Qualcomm devices? I did actually know about that bug, and then forgot about it again, and then bought a device with 4.4.2 and a Qualcomm processor. Dammit.
If so workarounds might be: when you use the camera, pay attention to the battery drain afterwards, in case it has activated the bug. If there's a drain, reboot. Turn off the "Smart screen" and "Smart video" settings, since having them on would also activate the camera, which could also trigger the bug. I had those "Smart" settings on until yesterday, so maybe that's what was causing the problem for me.
And in the meantime, cross fingers that LG will upgrade us to 4.4.3 or, preferably, Android L, thereby squashing the bug.

LG had patched that........
3G/4G is very much the reason of all battery drain on my device, today I've gotten alright battery stats with no data connection except for WiFi, haven't deactivated anything but data and used my phone for a lot of youtube/browsing/ chatting. So I believe if you cannot go above 5 hours of onscreen, it's properly due to high usage of camera, or data and WiFi running when not in use

I never had that issue after using camera. You need to check if the process is starting on setting/battery. (That will not start because LG has patched that at least on my country, because I never have that)
I don't know what's going on. Today I didn't use the camera, and the battery seemed fine, and then I took a photo, and it started draining at 1-2% per hour again, so that made me think I'd found the problem. But then I hear it's patched, and anyway if it's the classic 4.4.2 camera bug, it should show up as mm-qcamera_daemon being the process using all the battery, and it doesn't, it showing Android OS doing so. I feel like I'm back at square one, not knowing what the problem is or how to workaround it, and thinking I have to send my new phone back...

Your problem is fast dormancy for sure. I told you that a few post back..
LG comes with fast dormancy activated by default for all operators and some of them dont have fast dormancy so make a fast 3G battery drain. If you drain 2% of battery in a hour with wi fi you can install battery stats and see what app is eating your battery.
I get intermittent battery drain with either 3G or wifi.
But if you could tell me how to change the fast dormancy settings, I could give it a try.
Also, not convinced that it's an app draining battery on wifi. According to Android, it's Android OS, not an app. Or is the Android battery information so not reliable? In that case, can you recommend a battery monitor app?
Thanks.

When Android operating system is draining your battery, is an app on the backgrpuns. You can use better battery stats. Just search in google and will apear.
If Android OS is draining, its common i also have 10% of drain because of that. But it dont drain too much so you dont have to worry. My xperia m2 says android os 60% when idle, but battery drains normal so just dont worry. If you feel a big battery drain use your phine to 100% to 10% and give a sctrenshot of battery graph.
Press thanks button, you are welcome.
I have an LG G6 and a V30 on the Verizon network. On both, phone idle is using most of the battery. I've read several posts and searched the net without finding a solution.
I use a Samsung Gear S3 watch. Not sure if that could be the culprit.
When I Googled it, seemed like many others were also experiencing this problem. No one on this board is having this issue? Or has everyone figured out a solution? Thanks..
Why do you feel it is a problem? It doesn't matter unless your total battery life is not good to excellent.
Sounds like you just leave your phone Idle more than anything. I don't see a problem.
Sent from my LG-H932 using XDA Labs
check the battery usage ... find the offending app.
I am seeing the same: I don't use my phone very much, and not for gaming or video or anything very power consuming. So idle is by far the biggest battery drain on my V30 as well. The battery is still great on this phone, and it is quite frugal during use (as opposed to my beloved old Nexus 5, which was frugal when idle, but every touch of the screen would deplete the battery): I only charge the V30 every other night, and usually get 4-5 hours SOT on a full charge.
Battery stats attached. I have disabled most Google features (location reporting, always listen etc) but as you can see, Android Kernel and Android System remain by far the biggest app suckers. Lots of LG services buried in those. Some day I'll try and figure out which ones are the main culprits.

Either this is a bug from software or this is the way the phone display itself..
As long as it doesn't effect the battery usage, it's not a problem imo
The high idle drain is real, at least on my phone. It is NOT merely an error in how usage is displayed. If I left my phone completely unused, it would run the battery down in about 3 days, with no SOT. Significantly faster if I move it (say, in the car), slower if it's just lying on a desk. But even lying on a desk, it drains pretty fast. Even overnight, when AOD is turned off.
This is fact, not opinion. Of course it could be unique to my phone and the OP's, although a few other threads mention high idle drain as well.
As I wrote in my last post, the phone has a good battery AND a frugal display, which means it's not a problem for most. Indeed, owners who use their phones all the time will appreciate how frugal it is in active use -- although they too would get even more SOT if their idle drain was lower. Obviously it is a bigger problem for owners who use their phones less, and who want to charge it only every two or three days to preserve battery health.
I remain convinced that the drain is caused by some of the LG or T-Mobile services on my phone, which would cause it to be buried under System or Kernel usage in GSAM. I just haven't had time to dig deeper into which ones it may be. If others have suggestions for which apps or services are the culprits, I'll be very interested.

I'm actually seeing the opposite on my phone. Idle battery drain is minimal, but I feel like it drains a bit faster than others while in use. I did disable a lot of carrier/LG bloat I'm sure it's helped with idle battery usage to a degree.

Thank you for sharing this. Good to hear that your idle drain is low after disabling LG/carrier bloat. Makes me hope that if I take the time to go through it on mine, I may see improvement. So far I uninstalled a couple of LG apps through the Settings/Apps menu, that's all. I've meant to do more with ADB, just haven't had the time yet. Your post is encouraging in this regard.
But puzzling that you find active drain so high. My old Nexus 5 was like you describe: Very low idle drain (lean custom ROM and not many Google apps installed), but drained fast whenever I used it. As described, the V30 surprised me by doing the opposite. Hmmm....

I think it's kind a normal to find idle taking up most battery if you're not using the device (i mean less), because when i compare it to a9 pro, it's the same actually.. when i use it often, screen will take the most battery percentage.. but if i use it less, device idle will be the most at the top..

If I left my phone completely unused, it would run the battery down in about 3 days, with no SOT. Significantly faster if I move it (say, in the car), slower if it's just lying on a desk. But even lying on a desk, it drains pretty fast. Even overnight, when AOD is turned off.

If the phone is flat in 3 days, then your idle drain rate is 1.25%/h. That's elevated.
It should be possible to improve depending on what the causes are. Could be apps, could be apps you need and then there is the network.
As a simple test, charge up your phone before you go to bed. Then leave it there, untouched with AOD off.
In the morning, settings - battery - battery usage - estimated time remaining <-- how much is that ?
Your battery will have to drop to at least 98% before that info is available which in your case could be sooner than morning maybe in a couple of hours
Indeed, owners who use their phones all the time will appreciate how frugal it is in active use -- although they too would get even more SOT if their idle drain was lower. Obviously it is a bigger problem for owners who use their phones less, and who want to charge it only every two or three days to preserve battery health.

True. After two days you've lost half the battery. Ideally it should be less than that.
I just haven't had time to dig deeper into which ones it may be. If others have suggestions for which apps or services are the culprits, I'll be very interested.

Do you have access to a PC with adb installed ?

Thank you for the response. That was posted over a month ago, and I finally did get around to disabling (or rather, uninstalling with ADB) a bunch of LG apps and services. Also some T-Mobile apps after switching to AT&T MVNO. That helped a lot, and I am now down to approx 0.5%/hour idle drain. That's overnight, mind you, and I still find it somewhat high considering AOD, Location, Bluetooth, NFC are all off, and the phone is completely still for 8-9 hours.
But I can now generally recharge only every three days, and still get 6-7 hours SOT. I guess that is great for any phone. Sometimes and I have to use Battery Saver to make it that far. It helps a lot to reduce battery drain, both during idle and use, and has no noticeable effect on usability.
Also on the positive side, I haven't had any of the lag issues mentioned by others in various threads after disabling apps. In fact, it is even smoother than before disabling them. I did go a bit too far, as I lost the ability to Google Cast the screen -- strangely, as I didn't touch Google apps or services. Also, I lost LG SmartSettings, which I didn't actually use, but didn't mean to lose either. I kept the SmartSetting app, but apparently one of the LG task related apps I disabled caused it to disappear from Settings. No other issues or functionality losses -- except the ones I wanted to lose.
So I am OK now -- though I still think idle drain is higher on this phone than it should be, even after disabling LG's duplicate and redundant services and turning off known battery draining features (AOD, Location etc).
Edit: Thanks again for your response and offer to help. Re-reading my post, I don't think I fully acknowledged that.

By adb i was referring to granting a one time permission to the better battery stats app. Will be a good next step if you've not used it yet since you've done a cleanup already.
The dump file will reveal what your phone is up to when you set it down and whether further improvements can be had if feasible.

How did you measure that rate ? wonder if its possible to reduce it further. Up to you

6-7h/SOT is normal for the v30, on wifi or bands 12 & 20 with heavy use.

If you're interested in exploring further with BBS, let me know. It has a strict procedure to follow which i can walk you through

I did grant usage stats permission to GSAM. Otherwise it wouldn't have shown the details in those screenshots.

GSAM can show stats for various time periods, including custom ones. I generally check it in the morning after it's been lying on my desk or nightstand overnight for 8-9 hours. That's the ultimate Deep Sleep condition.
MY cell radio uses a bit more after switching to AT&T and returning the signal booster that T-Mobile provided me. The booster didn't improve T-Mo weak's reception in my apartment, but it DID provide a stronger signal to the phone, so it doesn't have to work so hard to maintain it.

I'll take you up on that. I haven't used BBS in years (different phone) so not up-to-date on it at all. I'll follow your procedure, just tell me what to do.
Thanks again. Much appreciate your help!
Edit: I downloaded and installed BBS 2.2.2.0. Holy crab, I can't believe that thread is now 3300+ pages!

Good, this will allow you to compare both tools and see which one is more useful.
Now you need to give BBS the permission in ADB as shown here
adb shell
pm grant com.asksven.betterbatterystats_xdaedition android.permission.BATTERY_STATS/
That's it. Switch off Developer options.
Then go into BBS-Settings-Advanced- (scroll to the bottom and click System App) and verify it says BATTERY_STATS granted. Cannot proceed further otherwise.
If ok, back out of advanced and tap 'Watchdog' then enable
Next, try a dry run. AOD off. Let the cell be on since that's how you use it and wifi.
What battery level is when you start the idle test matters. Can be anywhere between 50 to 95 but not over or under. More consistent data between those two points.
Let it rest for an hour. Do not touch it during this time. if the phone rings and you answer it then your log is going to get polluted with irrelevant info. It's useless, have to redo the idle test. The not touching it matters a lot.
When time is up, in the app under summary there are a couple of dropdown menus. Select 'Screen Off' instead of 'Boot' for the left and the menu next to it, select 'Screen On' instead of Current. Telling it to print data only during the time screen last switched off and turned back on. Very handy. As you can use your phone before the test and when ready to do the test it doesn't matter where you start within the limits mentioned. Screen off to screen on, That's what watchdog does.
After that, Look for the share button at top and select Dumpfile then Save. The txt file will be saved in emulated/0 so in LG's file manager, Internal storage, scroll down, it should be there by default. file name betterbatterystats- date-time.txt
Post that txt file as an attachment in your next post. Hopefully, on the V30, BBS will record under the sections, partial wakelocks, alarms, network which are required to understand where wakes are coming from. If this part is successful then you can go on to do a real idle test.
There are three key points here,
- idle test done when battery between 50 - 95
- your screen on during the idle test cannot exceed 1 minute. No touching
- getting the correct start and end points meaning you selected screen off to screen on to record in the dump.
Get this down right and you will be ready to do a real idle, test. There is one extra condition now. Test cannot be less than six hours. Can certainly be longer but not less than 6h. This is where the no touch rule starts to grate but that is the minimum time required for any wake locks to make themselves known. Getting the procedure right means you don't waste runs. And you will be doing several as you hone things
A bit rigourous but this is what the creator of BBS and the guys in that 3k+ thread insist you do to get the most out of BBS. They won't look at your dump file otherwise. Redo it they will say

Thank you. I'd already granted it permissions (BATTERY_STATS and DUMP). But I cannot install it as System app, since I am not rooted -- which it promptly tells me if I try. I was looking for somewhere to confirm the permission, but didn't find it.
Anyways, I started the Watchdog. I'll be charging it overnight, then do the dry run tomorrow after the battery has dropped below 95%.
Thanks again. This will be interesting!

Ah, i wasn't clear, install as a system app isn't required, that screen is just to check if the permissions took.
A popup appears saying root is required and disappears after a second or two, if you see the word 'granted' then you're good to go. Fingers crossed the right sections get data
