How to deal with low signal battery drain? - Vibrant General

I monitor battery use carefully and freeze apps that cause unnecessary drain. I use 2g only. I use Better Battery Stats to identify wakelocks. Everything in my phone seems set up properly but I cannot figure out how to deal with battery drain due to a poor signal in my area. I have tried using airplane mode but this results in exchange/email, friendcaster, and gmail (among others) wakelocks. I have no issues with wakelocks on the two tablets I use when wifi is turned off but turning off data on the Vibrant seems to offer no battery saving benefits. Even when I turn off syncing completely, I run into wakelock issues. I'm using bionix right now but I have had this issue with many ROMs.
Bottom line: If I leave data activated, I get significant battery drain due to a poor signal. If I turn data off, I get significant battery drain due to wakelocks. How do you guys handle this problem?

Hi...
In my opinion,
1. you try diffenrent modem for optimal signal fetching....
2. Try Juice defender like apps that prevents unncessary battery drain to a greater extent, if it is PRO version, then it is worth like anything.....
3. Try some CPU slide or voltage control to reduce the battery drain...
After sincerely trying this for about one or two days stick on to the optimised parameters, definitely you will be get rid of battery drains.....
Dont mind me if it not much useful....
All the best...

Are you running the original Bionix?? That's old school stuff. You can try different modems to get better signal, but a bad signal will drain the battery no matter what phone you have. At least it has with every one of my phones. I would start at fixing permissions under ROM manager, reboot into CWM, repair permissions in there, reboot and see what happens. That has fixed app issues for me before.
But really, if you are still on Bionix, I would recommend updating to Fishmanmod's updated version of Bionix with a clean wipe. Could give and ICS rom a try, also.

I'm using fishman's mod of bionix.
I think I found a solution to my problem. Jakub Klos' email fix prevents wakelocks when data is shut off. You can find the file and info here:

Are you sure it's a signal issues? Maybe it's an application that's causing the drain. Have you tried reflashing?

I believe so. Even when all my accounts were set to manual, when I left data on during the day at work, the drain was out of control and there were no significant wakelocks. The email app I had been using was also causing battery drain when signal strength was poor. I used the aforementioned email.apk all day today with exchange set to push. I turned data off when I didn't need email or when my signal was poor (most of the day) and the email app didn't cause any wakelocks (it did before). After 13 hours (1 hour of display time), I have 65% of my battery left. BetterBatteryStats shows no significant wakelocks.

Warning to those with battery drain on freex10

I was getting really fantastic battery life until today when I installed dolphin hd. I'm not sure why, but the moment I installed that, my battery could literally be watched dropping, even when it wasn't open. Once I got rid of it, my battery life then went right back to being great as it was before. The odd thing is, under battery usage, it wasn't showing up when it wasn't running, yet as it was the only change I made, and the sole factor in the change in battery life, I'm positive that's what it was. I'm curious how many people experiencing bad battery drain are using this browser.
i am using dolphin mini and dont think i have battery problem.
maybe you should try it.

I have all these and my battery life is fine, I don't think you get what I said at all. I think dolphin could be the cause of so many people having battery troubles, as once I installed it I started experiencing the same things they said, and then once I uninstalled it the problem was gone. I am back to about 1% an hour drop hen in standby, however with the dolphin installed (even when it wasn't running and I wasn't connected to wifi or 3g) I was dropping about 5-10% just in standby per hour.
Hmm.... might remove it and see if I can see a difference.. but my battery life isn't even horrible. A little worse than before maybe. But I'm getting a solid 10 hours at least.

freex10 severe Battery drain with latest X10i official SE update.
Running Beta 4 after factory SE updated yesterday on my X10i. I have severe battery drain. 89% after loading the freex10 beta4 with apps zip install and a TI restore of all my prior progs. Left the phone plugged in and charging overnight and this morning it was 4%. I am not using any special browsers. I am using Advanced Task Killer and killed all the programs before leaving the phone. Any ideas??
I really wish there was a way to dual boot with xrecovery.. that way we could use stock SE during the day because it has better battery life, and when we are near a charger we can use 2.2
I had the battery drain problem where I was losing 5 - 10% per hour after upgrading to beta 4. While I cannot prove it I think the drain is related to the baseband upgrade and how it interacts with 3g on AT&T. I can't turn off data as this is my work e-mail device. After some experimentation I found that switching to 2g "fixed" the problem. I took my phone off the charger 4 hours ago and with moderate e-mail use, 1 30 minute phone call and some XDA and web browsing I am at 91%. I added the 2g/3g to the power control widget and can quickly switch to 3g when I want/need the additional speed.
One other unintended benefit I found from 2G. For some reason my phone will not drop in certain areas where I drop calls every time I am on 3g.
Possibly due to wifi?
Ok guys so I re-did the OE factory SE update and re-did the xrecovery to redo freex10 beta4. all went well but I was to sleepy to setup the wifi. This morning my phone was fully charged and ready to go. I came into work and turned the wifi on to use on our network. Phones been on standby and wifi is set to be off with the display. Its only been 3 hours and my phone is at 10%. Why is wifi drawing so much power even when not in use?
So far I saw many causes in 2.2, check my list here
> Dolphin HD (from this OP? - unconfirmed)
> Stock Email get partial wakelock with exchange server.
> Dialer - partial wakelock (you might not feel it, but it is, compared to 2.1)
> Dialer - drainage when turn 'turn to silence' on (Call setting)
For Dolphin, well as I trusted in android system, I believe there might be something else 'between' dolphin and the battery, I don't think it's the dolphin itself. Since it doesn't report anywhere between spareparts or battery usage, or even CPU usage. I must admit that 2.1 is doing better in term of 'system stability' (not about hanging, crashing - but to handle when something go wrong)
I also must admit that using ATK in 2.2 is likely cause trouble, I used to have battery trouble and there was no way out before I turned to ATK. well, thing got 'weird' (it was not worse) If you feel something wrong, 3G trouble, some stupid force close, try disable ATK.
I never used ATK in the fresh install. Posibly the stock E-mail however I haven't set that up either. Its a shame as the rom is real good and appears stable other than the battery drain issue. I've already tried the Xrecovery wipe of battery stats, cache, etc with no luck. I may just stick with the factory SE rom till freex10 is no longer a beta..

gotta give this a try
it's been driving me crazy wondering why my batter drains so fast
Worth a shot for sure! I get 24 hours easily with heavy usage... It's a lot better for me than beta 3 was
I use to have bad battery issues with this rom but then I install juice defender and it has done wonders for me. Task killers help but nothing like this app does.

I'm using beta 3 with constant 3g and dolphin hd. No problems. Batt drain is as usual with 2.1 original. I get about 1-1.5 days of usage, sometimes even 2.

FIX and INVESTIGATION: Android OS (battery drain) problem on Gingerbread

CASE CLOSED!!! Please read bottom part or flash stock GB 2.3.4!
I have posted this already on another thread (almost word for word) but I just really want you guys know and not panic about this problem and avoid going through difficult fixes like deleting system apps, recalibrating battery or even resetting your phone.
Since JVK was released, many observed that Android OS sometimes get hungry and devours battery. For some reason it is triggered to go berserk. Others say that the main culprit is the Auto update app. But other apps like Google Maps, Latitude and even just in a place where there is very low network signal or Wifi reception could also trigger this problem.
Now, I have a very simple solution: Turn off device, remove battery for a minute, put it back then turn it ON. Yes it is just that simple, REBOOT YOUR DEVICE.
Yeah after you turn on your device Android OS is still on the top of the list with high percentage but I believe it is just as it is because it previously consumed a lot of battery. All you have to do is observe again for an hour if your battery is dropping again, look into the graph and see if it is still steeping to the bottom. If it is dropping like Mt Everest, do the procedure above again.
If not, you will observe that after a couple of hours Android OS's percentage is getting low. Problem is fixed, (temporarily though).
Why go through deleting apps, recalibrate battery etc when you could just turn off your device for a minute?
I have experienced it a lot of times already (one of the first users who upgraded to JVK) but it doesn't bother me anymore. Turning off then on your device is very simple ain't it?
I highly advise that you do not touch anything on the sensitive part of your phone as there is no known single root of this problem. Just like I told you, many situations or apps could trigger Android OS to go berserk. Until there is no definite solution to this problem, I suggest you do the above procedure and save yourself from going through the pain of removing system apps, battery calibration or even hard reset.
By the way my battery usually lasts 3-4 days unless I made Android OS angry again.
INVESTIGATION
INVESTIGATION CLOSED!!! The culprit is caught. But the fix is not so simple. Only Samsung and genius devs (apparently the fix requires closed source modification) could fix this. If the problem occurs on your device, just do the temporary fix above. Please do not try to mess with your device for now.It is now fixed in XXJVP 2.3.4!
Click HERE and read the bottom part for more details.
All this is due to Tatsuya who pointed us to the right direction. A big thanks to him for helping us in this investigation. CASE CLOSED

Guys if you want to help out please please please dial this *#*#4636#*#* and check "Usage Statistics" and let us know the top 3 items on the list! (highly suggested by {Angel}).
Below are some of the possible culprits currently pointed out by some users (I will update the list based from your feedback):
1. Software Update service
2. Google Maps
3. Latitude
4. Low network signal
5. Very low WIFI reception
6. Auto updates in Market
If this helps, a simple thanks is enough

Those of you with high drain, you can also check battery history through *#*#4636#*#* and see what you have under other usage 'running' and see if your phone as not been sleeping lately.

That is why I suggested that they report what could be the possible triggers, like apps or situations, that make Android OS to awake and gobble up the battery. If we could just pinpoint those triggers maybe we can now figure out the root of the problem. Your fix of removing a system app, the auto update app, is not even the single source of the problem. We just do not know if that app is an essential app or not. Sooner or later you will have that problem again.
I am not saying we should just sit and wait. All I am saying is if you are a plain user and you do not know the exact root of the problem, then just do what I suggested.

Rebooting works, and it seems to be working until you start some apps again. I have the same apps installed as I had on JPY, but JVB drains my battery dead in half a day.

Did what you suggested and pulled the battery at 30% waited 5 minutes and put it back in.... 1hr later it was at 35% (WTF!) and 30min later it was at 38% (WTF!)
im assuming its recalibrating?
Not necessarily. Maybe the battery meter is anticipating the fast consumption rate of Android OS that is why when it got fixed, the meter is able to readjust the readings based from the current consumption rate of your phone. Good to know it helped
Maybe use the 'forbidden' task killer? Works for me... Maybe im imagening it but works.
Btw my battery goes quickly down after getting below 25%. My battery not calibrated? Should i.calibrate it? I have this program to do it but am afraid that calibration goes wrong. (example what if my battery is 95% and will calibrate to 100. What if.i charge my battery higher than this.. Will it show 104%? Or will android stop working for it cannot be displayed in the notificationbar.

Sent from my HTC Desire using XDA App
You do not have to recalibrate. Cm7 has a known issue about battery. I think you cannot charge past 94 or 95 percent and battery usage is a bit terrible. Please refer to cm7 thread for possible fixes, (the last time I checked their thread, they say it is probably kernel related).
Just turning off, pulling the battery and turning on does do a lot for me! i went from 10% per hour to only 1%! great thnx!
Hi,
About battery drain in gb, once fixed the wifi sleep policy issue ( by setting it to "never") u shouldn't have batt drain, but i've installed green power ( juice defender do the work too i think) to get some wifi management possibility back and it improuved my batt life.
But never the less, my battery won't last more than one day of hard usage ( being hanged on xda all day long, for instance ;-)

Guys, on Gingerbread I've had battery drain two times:
1. Had about 14% drain in 3 hours all of a sudden, without doing anything at all. Just started going down for some reason.
2. This morning, saw about 40% drain in 7 hours..
And, both time I solved it by Clearing Memory from the Task Manager.. Went back to normal 2-3% drain per 6-7 hours after that..
So this might also be a solution. Go to Task Manager, RAM tab, and Clear Memory..
i'm on ginger also and my battery acts weird. 2 days ago i charged my phone over night while it was closed. the battery holds for 15 hours with massive use.
last night i did it again, but today it went from 98% to 80% in about an hour !
this is really weird.

Did you manage to check first what is running on your device by looking into Battery Usage settings? I think you have a case of rogue application running in the background.
If you have not rebooted yet could you please attach a screenshot of the battery usage list and graph? In that way we might possibly identify the app running prior to the clearing of memory. Thanks!

EC01 Improved Battery Tip

For my individual phone I discovered that EC01 plus Juice Defender has drastically improved battery life. I will say previously with SuperClean that Juice Defender had a much smaller effect.
That means you have something that's using a lot of data.
Turn of Contact Sync
I've been using EB01 (not EC01) for about a month, and having horrible battery life.
Using the battery monitor (Settings->About phone->Battery use), I traced it to an internal process, sometimes called "Android Core Apps", also known as android.process.acore. I also used an app called "System", which showed that android.process.acrore was regularly pegging the CPU at 100%.
A little reading on the web suggested that it might be related to syncing of contacts. So I did a little experimentation and here's what I discovered:
- If I sync to ONE gmail account, it consumes battery pretty fast (about 5% an hour). If I turn off sync (but leave the contacts on the phone), it gets better, but not perfect.
- If I sync to TWO gmail accounts (for example, home and work), it consumes battery at a tremendous rate (about 10% an hour). If i turn off sync for both accounts, it DOESN'T GET BETTER. The CPU continues to spike and the battery life is miserable.
- To stop the drain, I had to BOTH turn off all contact sync AND erase the contact book. (Settings>Applications>Manage Applications->All [tab]->Contacts Storage->Clear Data). Then my battery life was PERFECT. Android.process.acore completely dropped off the battery use list. Of course, I have no contacts on the phone at this point, but my battery life is great.
My theory is that Samsung's custom andress book is really screwed up, especially around the "linking" feature. It just churns and churns, eating battery. It gets worse the more contact books you sync.
The next thing I plan to try (when I have time) is to export my gmail contacts to a file, and then import them into the local contact storage. I will try to de-dup them before hand. I'll let you know what I find out.

CORRECTION: I originally wrotet that this data applied to EC01. I am actually using EB01, not EC01. Message text above has been updated.
EC01 has only been available for a week or so... How have you been using it for a month?
My bad. I'm using EB01, not EC01. I have no experience w/ EC01, so can't comment.

Like the facebook widget. Delete the crap that's wasting data instead of crippling it partly while letting it continue to be wasteful.
I found JuiceDefender only hurt my battery life, and caused quite a lot of syncing to break (and use Push for anything that supports it... that'll cause its battery use to quickly approach zero, while getting instant updates, instead of 30min-multihour delay!).

Under Network Usage in Spare Parts there are a couple big spenders. Android System is up there no surprise but something labeled as "0" is by and large the most battery life costly. When I tap on it, Spare Parts force closes. I do remember having something named "1013" do the same thing on SuperClean.
Learned very belatedly that NoLED has been one of the big battery drainers for me, even on various versions of SC (NV). Also has been said in the past: sometimes things happen during a ROM flash that cannot be replicated when you reflash so this may explain why I kept restoring back to EB01 to have half a decent battery life until they started posting steps in Dev on clearing things out using ODIN Stock EB01 w/ Pit. Quite educational.
Juice defender is a placebo...it doesn't actually increase the battery life. If it did, Google would've applied that in default.
I have noticed that I don't receive pic texts while using juice defender because it turns off 3g. So I don't use it.

You probably never "adjusted" google talk, and set it to not sign in automatically..
And then there is that weird option at the bottom of the display settings.. disable that as well..
Also the news and weather application refreshes every so often, adjust that as well..
JuiceDefender helps with the phone in your pocket all day/no real signal issue..
If you turn your data radio off, the phone will still ring and your sms' will continue as normal both in and out.. see what the battery life is then..
Also (assuming that you are rooted) there is an excellent kernel, OTB 1.2 which would also allow you to under volt your phone..
But the above settings will help any fascinate if you have not already done so.

You'll still get text/calls, but not email/mms/gtalk etc. Text and calls use 1xrtt data and mms/email/internet/etc. use mobile data. I use a manual "juice defender" which is turning off mobile data in my notification toggles.

Disabled google talk auto sign in. Also disabled that power saving mode in display setting. The display option uses battery?
That is a suggestion. Going to see if that helps my battery.
Juice Defender has drastically improved my battery life. Rolling with EB01 radio + Community Rom 1.1
Issue is since it completely shuts off data I don't get incoming Google Voice texts. A shame since I use GV as my primary number.. I really need a better solution. I would even be happy with a thicker Fascinate if the battery life was decent.
I'll try EC01 and see if that improves anything.
I've had horrible battery life ever since the first Froyo leak. I've tried different Rom's, tried turning off certain things like wifi and rotate, and I've tried different radios and different kernels. I've also done the whole battery reconditioning thing and it hasn't helped either. My apps haven't changed since 2.1 and I was getting upwards of 30 hours on one charge when I was running DJ05. So, I have been trying to achieve that level of battery performance since then but with no luck until now.
I just recently followed Adrynalyn's directions in how to get to ED01 quickly so I could try out the ED01 radio. After having the ED01 radio and then flashing to the latest Evil Fascination Rom, I am pleased to report that I am achieving the battery performance I had with DJ05. Oh, I forgot to mention that I'm running the latest OTB TW Kernel by Nemesis2all and I'm not undervolting. I'm running at 1000 mhz stock.

awesome! just what i wanted to hear. I'll be flashing this tonight
Went through the fairly long process of getting the ED01 radio on my phone. Unfortunately I see no difference.
After 7 hours of being unplugged and with very light use I'm at 45% battery, similar to every other Froyo build I've encountered.
I have Beautiful Widgets and set the refresh to every 3 hours, but I'll try disabling it just to see if there's a difference. After that I'll get into some undervolting, then maybe the Evil fascination ROM.
Is there a way to monitor network traffic?
i dunno how everyone is having bad battery life.. ive been at work for 9 hours.. texting all day, n pissing around with voltage control.. and i talked to a drs office for 36 mins.. and im at 75% my brigtness is set to max... and i have full 3g service.google location is on, gps n auto rotate on all day.... ive rebooted my phone twice.. personally.. ide reflash and start over..

It might not just be the radio that's resulted in me having great battery performance. It could be the combination of Rom and/or kernel plus the ED01 Radio. I'm not sure. All I know is that after I went to the Ed01 radio and flashed Evil Fascination (latest) Rom plus Nemesis2all kernel, I am achieving outstanding battery performance.
I am only syncing once daily with SNS Facebook and Twitter. I have Weatherbug and widget syncing about every 30 minutes. Tweetcaster is syncing about every 15 minutes. Tapatalk and Foursquare are syncing about every 15-30 minutes I think. That's about it for me. I don't have too many programs syncing.
I would try flashing Flashing the Rom and Kernel I mentioned and see what happens.

[Q] Battery life terrible, despite trying all the supposed "fixes", hardware problem?

[Q] Battery life terrible, despite trying all the supposed "fixes", hardware problem?
I got my N4 a bit less than a month ago by this point. I've rooted and tried most ROMS from stock to CM10.1 to PA, etc. However, my battery life is consistently not so good. Coming from a One XL on CM10, I was used to bad battery life, but I expected the N4 to be better.
I don't have any screenshots, but here are my averages:
Time on Battery: 10-14 hours
Screen on: ~1.5 hours (usually, never have gotten over 2.5)
Android OS kept awake: ~1-1.5 hours
I know I'm among the group of people with the problem of Android OS keeping the phone awake, and I see all of these kernels attempting to fix the msm_hsic_wakelock issue, but I'm still having that as well.
I'm always on auto-brightness, Google sync on (calendar, chrome, gmail), Google Now enabled, etc. I'm also always on data, usually 2 bars + (the signal never gets worse than yellow on the battery graph.
Lastly, on wifi, all of these issues are gone. My idle battery drain is also phenomanol on wifi compared to data or even no wifi + no data. In about 8 hours I drained ~8% even with the data off.
Any ideas? I'm getting really frustrated. I see people claiming 2+ hours screen time or 20+ hours on battery on stock phones! I'm nowhere near the average battery times.
I know I'm among the group of people with the problem of Android OS keeping the phone awake, and I see all of these kernels attempting to fix the msm_hsic_wakelock issue, but I'm still having that as well.

Android OS is not keeping your phone awake. It's one of those crappy apps you have installed that are causing a wakelock causing the phone not to deep sleep.

Use it to debug partial and kernel wakelocks (primarily partial wakelocks). Check CPU states using that app or download CPU Spy from play store.
It needs to be deep sleeping.
Google Now: Disable cards that you dont use.
Turn off auto brightness and adjust it to your liking (CM10.1 has a feature if you long press on status bar it will adjust its brightness so you can do it like that).
Use Franco Kernel r23 (it's the most stable one, if you want to experiment you can try r26).
Google Maps: turn off Google Maps Latitude and its automatic reporting of your location and uncheck auto reporting in your location.
https://play.google.com/store/apps/...xLDEsImNvbS5iaWdleWVzMHgwLnRyaWNrc3Rlcm1vZCJd use that app with Franco Kernel (or buy his app) to adjust its kernel settings.

Press the thanks if I helped. Will reply back if you have any questions or follow ups.
I've been on CM10.1 nightly 1231 for 3 days now and I can happily say that my battery is much better than before.
I've averaging 24-28 hours with 3 hours screen on with data only and usually charging at around 10%.
Always Enabled:
All Location Services
Google Sync
Always Disabled (except when needed):
Google Maps/Latitude location settings
Bluetooth, WiFi, GPS
Google Now cards that I don't normally use
Some things I've noticed:
- When I flash a new ROM and restore my TiBu (flashable zip or regular restore) I find that my battery life is average at best.
- When I flash a new ROM and fresh install my apps from the Play Store my battery life is good to great.
- Third party kernels can sometimes be wonky on this phone. I haven't tried Faux or Franco kernel since flashing 1231 because I've been getting great performance on CM kernel.
- When my kernel CPU is set to "ondemand" the performance is average at best. Changing it to "interactive" has helped improve my battery life... with no other kernel tweaks involved.
Apps like Facebook and Facebook Messenger seem to cause issues with my battery life also. When I was on CM10.1 nightly 1223 I had Facebook Messenger installed and my averages were 12-14 hours off battery. So by eliminating a few apps on fresh ROM installs I've been able to see the different effects they've had on my battery life. Basically any app that uses GPS can potentially be a battery hog even when the phone is not in use.
So from my points above are also some of my takeaways. Try a fresh install and watch what apps you install. Try a few different kernel governors (esp if you're on a custom ROM). You can improve performance by trial and error!
Good luck.
EDIT: zephiK's points above are also valid and I can confirm they've helped my battery life also.

I agree 100% with Facebook. The facebook app sucks your battery life HARD, especially if you plan to have it refreshing intervals. The app continues to request GPS location, so therefore because of that I disable the GPS on my phone completely (its that bug where if u have GPS globally on your phone you see it on the top left of your screen, and it doesnt go away). I leave FB all notifications off and manually sync it by pulling up on news feed. It's either that or check FB via mobile webpage.
Another thing I forgot is your refresh intervals. Make sure your apps don't have it on like syncing every 5/10/15/30/45/60 minutes. Set it to a couple hours more. using a twitter app? instead of having it sync in the background, just manually do it so you get all the missing tweets all at once. No reason to have it sync in the background randomly.
+1 on interactive. on Franco kernel it uses Interactive as it's default governor and it includes a lot of the latest interactive patches that really help out. It also includes qualcomm fixes with msic (not 100% but its better than stock), and newer drivers that will most likely be included in the next OTA.
Thank you for the replies everyone. In regards to all of the fixes you've suggested, I've tried all of them in the past week or two based on hours and hours of reading. This problem even exists on a freshly installed ROM with the bare minimum apps.
Now that I think about it, I wonder if there may be a problem with the radio in my phone. I live on a farm with an AT&T tower, yet I'm only getting "ok" signal, when I should be getting perfect signal. Called Google and just ordered my RMA, seeing as this battery problem has persisted from the day I first loaded up stock 4.2.1 on the phone upon receiving it.
If you constantly have a low signal, that will drain your battery a lot, because it has to boost the signal and that needs a lot more power.

This would have been useful in your original post. Obviously "worse" signal is going to cause more drain on your battery. Hopefully it's just a flaky radio for you but if the replacement has the same issues then it's something else and you should keep at it until you figure it out! That's half the fun with these phones.
My only concern was that he said android os was up there, so that means he has a app preventing his phone from sleeping.
personally i wouldnt take a RMA on poor battery life but as a result due to signal.... but yeah signal does play a huge factor in your battery life

Need advice about battery drain

Hey everyone, I purchased the 6P a week ago and I really don't understand the battery in this thing.... I'm coming from LG G3 which never faced battery drain during stand by. I am not even using the 6P (still haven't migrated from the G3) because of the unreasonable battery drain during sleep, I have WiFi always on and (no I don't accept to turn it to Never during sleep) I never did this with any phone anyway, my G3 doesn't lose more than 1-2% during the whole night (7 hours).
Please take a look and tell me if this makes any sense because I'm thinking of returning the thing if it's not just a software issue:

Taken today, phone left untouched at home.
Battery life is really hit or miss, many lose 0-3% during the night while others like yourself lose a ton. Try changing your WiFi to either 2.4GHz only or 5GHz only, as some found that helps out. Custom kernels can also control WiFi wakelocks, and I've found running Franco kernel does a great job at helping standby life.
How's the signal strength from within your home? Having a weak cell signal can assist in battery drain. However that's some serious drainage. I'm thinking you have one or more wakelocks preventing the phone to deep sleep. If you're rooted, greenify is a must. It has boosted my battery life by a ton. I would also try to get some more battery stats applications. Better battery stats was/is my favorite app but I'm not sure its working on MM

Although it is not convenient to switch between the 2 bands ( Work is on 2.4GHz and Home is on 5GHz) but I will try it to see if it helps any.
Do you think this will be fixed with software update? and is it because Android M or because 6P on Android M?

Signal strength is fine at my home ( never faced an issue with G3).
I haven't installed anything that can hog battery like that, I only set-up Email, Hangouts to Sync, I never used Greenify or any battery saving apps ( The battery should last as advertised with it's standard capacity), i'm not asking for a magical battery life, just what's expected of a 3450 mAh.
I'll post Sambatterystats results shortly.
See if WiFi scanning is turned off
Many say the battery drain issue really spiked with the update to Android 6.01. So it appears to be SW related, and not HW, FWIW.
I found my fix is as Geoff53 said above, install a custom kernel (Kylo in my case). And I use Greenify on top of it. Great battery life now.

I hope it's just the 6.0.1 .. because I really would hate to return it..
Well, I'd go as far as flashing a custom ROM if that would completely solve the problem, not just the Kernel.
I initially had bad batter drain, not now. Unplug 6:30 am and 10pm still have 45%. Use to be dead by 7pm. I found the culprits were bad apps that I thought were OK. Ebay, Amazon, Facebook, ESPN, Waze.... when I deleted these and a few more, then rebooted all was good. Haven't tried putting them back though. I leave GPS, WIFI, blue tooth... all on. Even have 3 mail apps all set to "push." I don't twitter though.
Make a back up with Titanium or MyBackup, factory wipe and reset and see if your battery improves with only basic apps and mail. Bet it's bad apps. If improves slowly add apps until you find the culprit.

In my opinion, the " Bad App" theory is getting a bit out of hand. I installed the same apps as on my G3 (never had a bad app on it) , and 6P has been factory reset and insatlled nothing at all, only logged into gmail and hangouts, and I tried with the (WiFi during sleep set to never ) then the drain is not as bad anymore but I lost realtime push notifications which is unacceptable.
Now if believe there are so many "bad apps" then we can have the Doze which is supposed to minimize app drain if not terminate it, but that's not the case here obviously, so I think it's actually specific WiFi bug on Android M and not bad apps.

This for me, was getting lovely life and slooooow standby.
Updated the latest build yesterday and Google Services has hammered by battery today, gonna give it a few days to settle down though
