mega battery drainage, help me figure out why.

Ok. so iam on darkys rom 9.3, used wipe and ever since my battery life has been bad since.
Take today for example,i pulled my phone off charge at 7isham listend to music for about 45mins, had possibly 3 hours of sporadic internet usage 3g/hsdpa, always turning off the 3g after usage. At about 130pm i had to switch to my 2nd battery.
this is a typical day for me, so its preeeety frustrating.
anyone have any ideas why or similar experiance and can share some wisdom?
cheers!

The first time you use the phone after a flash, the battery will be bad. A couple things to note:
Did you flash with 100% battery? A lot of people say this is necessary.
Did you calibrate it yet? When you do a new flash, use the phone until it is dead. Charge it without turning it on. When the battery is 100%, go into recovery and wipe the battery stats. Then use the phone again until it dies. After that normal charging patterns.
Some people say that they get better battery life with certain kernels, and whether or not you have lagfixes. I use speedmod and I'm getting great battery life.
Check all of these and see if anything helps.

Clue your rom if you did not have battery drain before .
jje

First think: have you installed any programs that need constant internet connection, like skype or facebook? To check whether this is a possibility check battery history, when cell standby is absurdly high even though the screen was on some time it's a good indicator something is constantly downloading (That only works if you used your phone since unplug, I have 72% for cell standby because I never turned the screen on since I charged it: )
If you ruled that out check whether your modem is appropriate for your region.
After that you should wait and let the phone run down to very low percentage or even let it turn off itself. I don't believe in wiping the battery stats, the battery will calibrate itself with every charging cycle. just let it drop under 10-20% and then charge fully. That helps me.
If the drain does not get better after 2-3days fully charge your phone and reflash the rom with the kernel

I've got the exact same problem with my girlfriends SGS. I got her this phone because it is a bit smaller and lighter than my desire HD, and it supposedly has better battery life....but at the moment I'm not seeing it.
Her phone seems to go at 30-80mAh at sleep, whereas mine will be under 5. She doesn't have any apps that I don't, and I can't figure what is causing the drain based on the running apps.

How do you know if the modem is appropriate for your region? I've been dying to find that answer, searched several places but no luck. How do you pick a modem. I have an international GT-I9000 but live in north america.
Thanks

On the first link there was a tip to make wifi sleep when the screens off, I did this an noticed a major change in my standby(screen off) battery life, it dropped 1% in like 6 hours rather than like nearly 10% Nisha, which I was noticing before.

I know, I read that post many times, but it's misleading, the country listed for each modem is just where the reporter tested out, not by any means comprehensively listing all the countries in which that modem would work well

Battery life in the last few days

Anyone notice a change in their battery life in the past few days? My girlfriend and I both are going through our batteries in just over half a day with no use. It's like the phone isn't sleeping. Looking at battery use Display is using all of the battery. I'm running CM7.0.3 and she's on stock. Looking at mine right now the phone has been on battery for 1 hour 34 minutes, and Display is taking 57% of the battery and I'm down to 84% battery.

Yes! I've had my N1 since January 2010. I stayed stock until recently when I installed CM 7.1 RC1 shortly after it was released. Battery life had always been great, both stock and under CM7, especially with SS4N1. Then, a few days ago it just fell off a cliff. I now get only about 7-8 hours, even with little to no usage. Before I'd barely lose anything if the phone wasn't being used (a percent every couple hours).
Now the Nexus One Battery Calibrator application shows a drain of ~200 mA or more constantly.
I've been tearing my hair out for the last few days, uninstalling apps right and left, trying in vain to figure out what's causing this. I even considered a full wipe and reinstall of CM 7, thinking that some system setting somewhere had gotten horked.
I've always had WiFi set to never sleep, since I'm usually either at work or home. I've also had preferred network type (*#*#4636#*#* -> Phone Info) set to "GSM auto (PRL)" for months.
I've not made any other changes I can think of that would've had such a drastic impact on power consumption. I didn't track all the app updates that happened around the time it started, so I suppose it could be one of those. But I've uninstalled just about everything and it's still happening.

I have the same issue! Just in the past week or so. I have about 50% battery then a hour or so later it's dead! I was going to get a new battery today but maybe it's a CM7 issue. I use the nightly as soon as they hit the mirror.

An update on this... There may be a big issue going on with T-Mobile or some recent update:
http://www.tmonews.com/2011/07/t-mobile-g2-users-suddenly-suffering-from-huge-battery-loss/
Looks like other users on different phones have the same issue!

Thanks for that article, Lost Dog. Makes me feel a bit better. At least I know I'm not just going nuts.
My phone still has increased battery drain even if I put it in airplane mode though. It helps, but it's still much faster than before. This makes me really puzzled as to what the cause could be. How could the cell network still be causing increased drain if the phone's completely disconnected from it? Some sort of configuration information it received that persists even after the cell radio is turned off? EDIT: I may be wrong on this one, see below.
Last night I tried a complete wipe (using Temasek's full format "Format-signed.zip" first), and re-installed CM7.1 RC1 completely fresh. I installed only the minimal Google applications and a couple crucial tools (my password safe app). However, I'm still getting the same quick battery drain today.
I hope we (or T-Moblie) can figure out how to fix this. It really cripples my phone as a useful tool to have such short life!
EDIT: I'm going to try a workaround I've seen mentioned in comments on the TMoNews and Phandroid articles about this: limiting the cellular connection to 2G/EDGE only. It seems to have made a significant difference so far. I may have been incorrect then about airplane mode not having an impact. I'd only been checking current drain with the N1 Battery Calibrator app, and never left it in airplane mode for long. Anyway, I'll post back later this afternoon with results.

Ok, so switching to 2G-only for the cellular connection seems to have made a HUGE difference. The drain rate seems to be back at around what I'd expect. Everything else I left exactly the same (WiFi on, GPS enabled, same applications, etc.)
So, I'm starting to suspect something may be up with T-Mobile's 3G/3G+ service in some areas that's preventing phones from idling properly.
Anyone else want to give it a try?

Interesting, I'll switch over to 2G only and see how that affects my phone.
I've gone as far as wiping everything and that didn't help so if it really is a t-mobile issue then that would shed some light on the situation.

I see the same trend when switching to 2G only. Very steep power usage with 3G then a dramatic decrease in the discharge slope in 2G.
T-Mobile has an issue. The trick will be getting someone there to listen.

Here is my screenshot. You can clearly see when I turned on 3G. Dramatic difference. Looking on the T-Mobile forum there are many people seeing the same issue but there's mostly finger pointing and speculation as to the cause.

I also got the same rapid battery drain since last Wednesday. At that time, I thought there may be a hardware/battery issue for my nexus one. To test this, I switched my rom from CM7 back to GB stock. After a few updates for the GB stock and used it for a day, same battery drain happened. So, I changed to use another backup battery yesterday. It did not help also. I thought it may be a real hardware issue.
Then, I found this thread and research a bit in the web. I found out it could be either caused by tmobile or google map updates. I first uninstall google map and reinstall the new version right from the market again. I also switch off 3G as well. No rapid battery drain for the entire day. The battery runs normally. When I came back home today, I turned on 3G, let it for a couple of hours, checked a couple of emails and received a 20min phone call. Everything seems to work fine. No noticeable rapid battery drain was observed. My conclusion so far is: this is caused by google map 5.8 update.
Try to uninstall it and reinstall the google map from the market to see if it helps.
Good luck.

Well, I'm willing to give it a try, but I'm skeptical. If it were the Maps 5.8 application that was preventing the phone from idling correctly, or transmitting tons of data, wouldn't we expect it to happen regardless of whether the phone was using the 2G or 3G radio connection? Sure, there might be a slight difference in the drain rate, but we'd still expect to see it in both cases. And yet the accelerated drain is alleviated completely by using only 2G. I have the Maps 5.8 application and can fix the problem by using 2G only. That indicates to me it's not an issue with the application.
I'll try uninstalling Maps tomorrow (I'm using CyanogenMod, so it's possible to remove it completely). Then I'll put the phone back on 3G and report back on what happens.

I've been experiencing similar battery issues the past week or so too. It looks like turning on 2G only seems to fix it, but what I don't get is why I'm still getting horrible battery life?
I have tasker auto turn off my 3G all together whenever my screen is turned off, and yet I leave my phone on my desk untouched all day and I end up at 40% when I get off work.
Wouldn't turning off 3G via Tasker be the same (or close to it) as turning on 2G only in the settings?
Hope t-mobile gets this worked out pretty soon!!

Glad I saw this thread. My wife and I both have N1s and have each been noticing unusually fast battery drain just in the last 3-4 days.
Last night I charged both phones to the same percentage, turned off 3G on hers and let them both sleep for a while. The phones are configured pretty similarly (stock, latest Maps installed, similar push settings etc). After about an hour and a half, my phone had lost 11% of its charge and hers had only lost 2%. That's enough of a delta for me to point to the 3G usage as the culprit. I guess I will be leaving my phone on 2G when I'm not using it if I am going to be away from a charger for a while.

It's NOT the Google Maps update.
Well, I did my experiment yesterday to rule out the Google Maps 5.8 update as the cause of this issue.
I'm running CyanogenMod so it's possible for me to uninstall Google Maps completely, not just the updates. I did so on Saturday night. Still set to 2G only, I removed my phone from the charger Sunday morning. A few hours later I enabled 3G. Later that afternoon I turned 3G off again.
I think the screenshot speaks for itself. Again, this is without Google Maps installed at all.
I asked around this weekend, and my friend's wife (also here in Portland, OR) is experiencing the same issue on her G1 on T-Mobile. Reading online I've heard about the problem affecting the MyTouch 3G, the G2, and many here with the Nexus One. The common elements seem to be: T-Mobile 3G service, particular models of phones, and some particular geographic areas.
Bottom line (IMHO): T-Mobile has a problem with the configuration of their 3G service in some areas, and it's preventing many phones from being able to idle/sleep properly, resulting in huge battery drain.

Here's mine, I posted this several days ago in the TMONEWS thread.

That's interesting. Even locking the phone to 2G/EDGE didn't have an impact? (not a Nexus One there it appears, what model?)
How did you go about disabling the 3G connection? I'm not sure if there are multiple ways to do it, but I used:
Settings -> Wireless Networks -> Mobile Networks -> Use only 2G networks
Really strange that even pulling the SIM didn't seem to make a difference. Or maybe that's not the same as turning off the cell radio entirely? Perhaps the issue is lower-level, like the radio constantly polling the tower or something even in the absence of being able to successfully register on the network for active use.
Does enabling airplane mode fix the drain issue for you?

This is a G2.
2G has been much better than 3g, but still probably only 3/4 of my former battery life, optimistically. I checked "Use 2g networks only", same as everyone else. The graph above is a little misleading, since I really saw better battery life, that initial flat and quick drop actually averages out to "decent", rather than "horrific.
At the "Pulled SIM and SD card" mark I re-enabled 3g, so the drain afterwards is still 3g related.
Pulling the SIM doesn't disconnect it from the radio tower, you can still make emergency calls/etc. so it has to maintain a connection I suppose.
Twice I hard-reset the phone, pulled out SD and SIM, and still had huge huge battery drain. Powertutor said IDLE draw was 1437mw on average, no SIM, no WIFI, just sitting there on my desk.
In Airplane mode it'll last for days...

I'm not familiar with Tasker. However, maybe it's just disabling cellular data use, not actually disabling the 3G radio? From what we've seen it appears the problem is very low-level, perhaps something to do with basic communication/negotiation between the cell radio in the phone and the towers, as there's no indication of particular application activity or significant data transmission that the Android OS is aware of.
In the T-Mobile support thread there are reports that T-Mobile is now acknowledging there's an issue with changes to their HSPA+ network in some areas.

I've had 3G off all day and my battery life is back to normal. I'm at 87% after at least 6 hours on battery. Yesterday I was down to less than 50% by this time. Luckily, I am able to be on Wifi at work so I don't have to deal with EDGE speeds, which make the Baby Jesus cry.
deliamber, you probably noticed this already but I'm also in the Portland market. It's gotta be a network issue.

I'm having the same issue on my N1 (I'm around the Portland area myself)
I did everything as well, 2g is the only thing that saves me..
Can't wait for a fix!

Battery Drain On s3 i19305

Hi, need some help,
I got this phone a couple of days back, its an unlocked one. Battery on the phone seems to be draining faster than i expected it to. The first time i charged it, it took 3 hours in the afternoon. By night it was 20% this was after playing games and downloading through wifi, so it seemed ok. I then put it for charge overnight. The next day it still seemed to drained by 7pm only used whats app this day, so i had to put for charge again.
Once fully charged (2 hrs) I shut off wifi, bluetooth, nfc and others. Switched off smart stay options and the display is set to lowest brightness (not auto). The wallpapers is also black so it will not drain battery. Overnight without the phone being used (only thing i set was alarm) the charge went from 89% to 78%. During the day I also find the charge still dropping pretty rapidly. I have included the screen shot of the battery from the same day. Between the first pictures there is no difference in use and still drops by 3% in 20 mins or so.
Is this a problem with the battery or is that how it is?
(Stock, no changes to rom)

Not sure if this is your specific problem - but one thing I've found that kills this phone fast is bad 4G cell reception. By default the phone runs as LTE/GSM/WCDMA (Auto) in Settings->Mobile Networks . If you are in a location with patchy (or none at all) 4G Coverage, the phone wastes an inordinate amount of juice switching to high-power mode on the cell radio searching for the elusive 4G/LTE ... Just like a 3G phone will deplete its battery extremly fast in a location with no/poor 3G connectivity (inside the 'secure' datacentres I wander into occasionally that have cell blockers, I can deplete the battery in a phone in about 3 hours just due to it constantly switching to high-power 'cell search' mode as it has no details on any cells to 'hand off' to....)
The difference is palpable... inside my office, if I have the phone on the right side of my desk closest to some windows, it will receive 'patchy' 4G and I'll go through about 60% battery over about 8-10 hours with intermittent phone use (most of the battery goes to screen time as I'm a 'fiddler' whenever I leave my desk for a coffee/break/etc...) If I place it on the left side of my desk, where the reception is much worse, it'll fall back to 3G and I'll go through about 80% battery doing nothing different...
I'm now in the habit of switching the phone to WCDMA Only when I'm going to be working in the bowels of the building, as there aint no hope of 4G there...Doing this drastically improves battery life.. Likewise if I'm stuck at home over the weekend, I leave it on WCDMA, as where I live has very patchy 4G as well and I only get it if I walk outside and down the street...
Just a possible reason for the excessive drain... at least worth trying anyway... *shrug*

Hi thanks for the reply. My phone does not show WCDMA in settings. It just has 2g/3g/4g/ auto OR 3g in network modes under mobile networks.

I have used an app called "Radio Switcher" to activate "gsm auto (prl)", when i open the app it seems to go into "Device info". It seems to work but "Network mode" does not seem to change.

I have uploaded the screenshots

Seems as though the system is using more battery than the screen itself.

The system seems to really take up way too much battery power. Mine is at 4%.
What are your sync settings? Especially for things like Weather, stocks, news etc. If you set them to sync every hour or so, your phone will keep running on the 3G network which will end up draining your battery.
Also, switch off motion. It's a cool feature, but it's not necessary. Same with auto-rotate.
Finally, use WiFi instead of 3G where possible. That saves battery too.
If you're rooted, download noFrills CPU control and reduce your max clock frequency on days where you won't get a charge. Phone runs well enough on 800mhz, but has a tendency to keep going at 1.4Ghz for no reason.
Otherwise, get a higher capacity battery

My sync is off, plus i have disabled sync for everything individuality and disabled all unwanted apps. Data service is also off, only use wi-fi. under motion only smart call is on and auto rotate us off.
I have uploaded a screen shot off after ti disable all these apps.(went to bed with 35% and was 28% in the mornin, turned wifi off before)

Will upgrading (official) phone to android 4.1.2 help (current ver is 4.1.1)? Current base band version is i9305BVALI5 i got an update on kies to i9305BVALI3. I don't think this is update to 4.1.2 is it?

I have updated to 4.1.2, and applied only gsm setting in mobile network. All apps are still disabled as before. The system still seems to be suing most amount of battery, more than the screen. I do not know what is using the system.

I have stared having the same problem a couple of days ago. Though I have sync enabled 0-24 for 3 gmail accounts, motions are on, screen auto rotate is also on. I am using nova launcher, almost all Samsung apps are frozen and most of time I am on wifi.
Now, this drain has nothing to do with the stuff I just mentioned (Enabled sync, motions...). I have all that things enabled all the time, and yes MPU and GPU are OC to 1600 and 640 MHz. But I was always getting >= 24h with ~3,5 h of screen on time. As I already mentioned, problem started a couple of days ago. Only thing which comes to my mind is that I have played with freezing / defrosting apps and I probably installed a couple of apps too. Like Beautiful Widgets and that's my main candidate to blame for this at the moment.
Though I am still not sure... Better than battery stats didn't show anything what could help. Network location locator or similar is at the top of the list of partial wake locks. But the time it hold the lock (About 25 min.) can't be the reason for such a high drain.
I have switched to HD Widgets, what I was using before (With this app one can disable auto location.) removed Beautiful Widgets, and turned off'Use wireless networks' and GPS in location services hoping it will help... So we'll see...

For me it still shows that adroid system and cell standby time is using a lot battery.

I don't get why android system and OS is using so much battery, everything is disabled. Network is on only GSM setting and i have network all the time, why is that also high? Does someone else also have the same problem?

If possible, install Better Battery Stats, maybe it will help you to identify the problem... In my case it is not of much use at the moment.

Strange idea: download an anti-virus and let it run.
Might as well give it a shot now, especially since AV is free.

I did an upgrade using odin to 4.1.2, the issue still remains though. The screen shots i posted is with the update.
So any virus should also be wiped out right?

[Q] 4.3 and battery drain

Hi all,
I was wondering if anyone is experiencing significantly worse battery life since the update. Today I kept my phone in battery saver mode all day, barely used it, stayed mostly in my apartment, and it's down to 15% after 12 hours. I'm pretty disappointed, as I had read that battery life was supposed to actually be marginally improved with 4.3.
Looking at my battery usage, the Android System percentage seems way up from what it used to be, though I might be making this up. Also, some of the apps I used a bit (Facebook, Instagram, whatever) aren't showing up in the usage stats.
I recall that my battery life wasn't so great for the first couple days after I initially got the phone, so I've been hoping that it just needs to re-adjust to my usage, but that hasn't happened yet. Otherwise, any ideas what I might try to fix this?
I've attached some screenshots of my usage. Any input would be appreciated. Thanks!

Its not just you, I also noticed worse battery life on 4.3.

Your not alone, use a program to monitor battery use ie gsam monitor.I noticed Google services is waking my phone like 220 times in 12 hours. My battery use is up and I'm getting like 9 hours less time because of it.

Me too! I thought battery life was supposed to be better with this. My phone is getting super hot now and dying fast,

I had similar issues, especially where I work. That place is on a fringe location where it switches 4g and 3g depending on how deep in the store you are. Where I work, I would always have 3g and the phone would get super hot and I'd burn through 50, 60 or more percent battery in 5 hours or so. It was rediculous. This afternoon, I said screw it and did a factory reset (I'm bone stock btw). Tonight, I worked a 7 hour shift and had 4g most of the time (never happened before) and the phone stayed cool to the touch. I lost about 20% battery. Just something you guys might wanna try. I know its a pain in the butt to do, but, at least for me, it seems to have been worth it.

Im running on stock rom, and my battery is much better than before. Maybe it has something to do with the rom?

I'm stock as well. I can try a factory reset, but I'd like to try anything else possible first.

Do you have an app that would probably keep waking up the phone?

Has anyone tried flashing the older radio over the new firmware? I think the signal is weaker with the new radio. Maybe it's switching back and forth between 2g/3g/4g causing high system usage stats. Can anyone try and report back?

I was at home on WiFi for almost the whole day, so I doubt that's the problem, though it's not impossible. I just installed WakeLock Detector a few minutes ago although it's only been running for a sec, so far looks like the Sprint Visual Voicemail app is using CPU wakelock a LOT. Could this be the culprit?

I'd buy that, though idk that it explains everything. I generally got good battery life, but I'm lucky enough to get fairly solid 4g at school and home. Work is the only place where it was iffy, and that is also where I had the worst battery life. The signal is not (in my experience) weaker. The bars just reflect data, not voice now, making it seem weaker. The only other weird thing is that the stability of my wifi connections is better than it was before the reset, and that I get 4g at all at work when previously I had to be at the end of the parking lot to get it.

Maybe. Ive also heard that theres a bug in chrome that also wakes your phone. Keep the app running to find out anyways. Ive disabled my visual voicemail since I don't use it myself.

Ever since update my battery is draining crazy. I just woke up and looked at my phone that was plugged in all night. And it's only 44 % charged. WTF!!

I take VVM off my phone, so its not that, at least in my case. I ran system panel yesterday and the top battery consumer is a process called binder_2. Its always that.

To me, turning off 4g made an absurd difference in battery life. There's a bug with 4g for sure. It never reconnects back to 4g for me once it switches to 3g and the drain is just horrible. I literally get 5 times better battery life out of the phone on CDMA only and truly, LTE is not 5 times better. I prefer consistency and better battery life over speed. So I just turned it off.
I read that up there claiming a factory reset eliminated the battery drain. I'll look into it. I just don't want to do a factory reset cause it's too much work.

Mine better! Signal bars lower both wifi & gsm, but... The true result better, I don't know why? Even no wifi signal bars, Internet still works,

That's very similar to what I had going on. I also had some issues where the phone would tell me x amount of internal storagespace remaining after installing certain apps and the reset (seems to have) fixed that too. If you use an app like Helium backup (no root needed) the reset might be a lot less painful, and I'm almost sure it will help you.

Yeah, I don't think it was actually VVM. I tried to let the WakeLock Detector app run for a while, but it kept causing my phone to restart randomly and I'd lose all the data it had collected, so I just uninstalled it. Looking like a hard reset's in my future. Balls.

No issues with that

Back on ecliptic 4.2.2, superb battery life is back. I'll get back on the 4.3 bandwagon again when we start getting custom kernels to fix what HTC broke.

Battery drain on Android 6 Marshmallow when IDLE

I've found several threads about drain, but all of them are Android 5 related.
Unfortunately I still have this problem on Marshmallow.
I don't notice it when using the phone, but while idle, it drains battery. Attaching the screenshot indicating I charged my phone at around 10 pm and at 1 pm next day it was already at 15%. Screen on time was only 2 hours.
Wakelock Detector does not work on Marshmallow. Installed BetterBattery Stats to try to find out what's causing this, but If any body's experienced it and has any idea what should I do, please share your opinion.
I've got MRA58R, bootloader unlocked, rooted, root aps list is: call recorder, adaway, betterbattery stats, es file explorer, gmd gesture control, nexus 6 double tap to wake.
Don't know if any of this is really important, but still. The rest is pure stock installed with full wipe.
PROBLEM SOLVED:
Nexus 6 on Android 6 has bug with 5 Ghz WiFi networks, use 2.4 Ghz and your battery will be fine!

Today before going to sleep I charged the phone to 100%.
I left it with wifi on for the night. In the morning after 8 hours I had 65% left. Screen on time was only 42 mins.
Attaching screens from battery and better battery stats.
What should I do next?
I would appreciate any opinion.
I wanted to try turning off Google Now (it helped my friend on Nexus 4), but on Nexus 6 I just can't find this ON\OFF switch of Google Now, how to turn it off?

I'm running pure nexus and get none of that. Around 6 hours sot. I'm not sure what would cause this, have not seen it

i bet, 99.999%, that its your wifi. try leaving it off your wifi then check idle drain. my work wifi does the same thing, so i rarely use it.

This. I had a similar issue a while back (although it didn't happen every time). One thing someone told me was to avoid the 5g band on wifi. Whoever it was correctly determined that I was connected to the 5g band of wifi at home and suggested I use it on the 2.4 instead. I did so and my drain dropped significantly. Now if I charge to full, leave it on my nightstand overnight off charge, I wake up 6 or 7 hours later and lose *maybe* 1% per hour. That's with wifi, bluetooth, gps all on etc.

I must say you've revived my spirit! I am always using WiFi in order to save mobile traffic, it's on even when screen's off.

And you've made my expectations even better, because I am using 5Ghz band all the time!
I will turn off WiFi now and give it a try! Thank you guys!
I will then test 2.4Ghz WiFi to see if it's really only 5Ghz WiFi that's causing the problems

I'll keep my fingers crossed for you that this fixes the issue. Additionally I should have noted, the person who suggested I use the 2.4 band instead of the 5 specifically noted that there is a documented "bug" where 5g wifi bands cause significant drain. That's apparently the reason that 5g specifically tends to be the culprit.

I have a similar problem as well. I have had wifi turned off all day today and its at the top of the list on battery usage. I have looked at every possible wifi option and turned it off. I dont understand what could be causing this. Im only bootloader unlocked, non-rooted, running stock image MRA58K

When you set it up did you set it to allow it to keep wifi scanning even when it is off for the location settings? I leave my wifi on 99% of the time and my battery life is great.

I dont remember if I did but I did turn that setting off when I was trying to diagnose the issue. I don't know if maybe it's a 6.0 bug that needs to be fixed. Good thing that being a nexus I hope it won't take too long.

I updated the firmware on my router and after doing thus none of my devices would enter power save mode on the 5ghz radio anymore and drain is now massive (check your router logs)
I tried flashing back to the prior firmware but still no go, so it must have been a driver update on the Quantanna radio as that's the only thing that was updated and it's a known issue with my particular model.

That helped me! Thank you guys! I connected to 2.4 Ghz and lost only 6% overnight!
I wish this information was easier to find, I'll update first post when I get home, it'll probably be useful to a lot of people.

It is a known issue with Quantenna radios on multiple routers; my ASUS RT-AC87 is one of them. Specifically as you said, on the 5GHz band. Switching to 2.4GHz wireless can fix this for the time being on Quantenna-based routers.
I've also had times where my battery seemed to have excessive drain if the cell signal dropped to non-existent; the N6 appears to drain fairly quickly searching for a signal. Unfortunately, AT&T occasionally drops in my house, and that's the carrier my work is on, so I have to live with it.
