Hey guys,
Just got my Epic yesterday.. coming from the G1 with lots of experience loading and tweaking ROMs and dealing with same/similar battery issues.
After unpacking the Epic I used it and let it drain down to zero before recharging it; after a full recharge, I loaded up the 7 screens with widgets and ran a live wallpaper (fish). I didn't really use the phone much at all and the phone went from 100% battery down to zero in the span of only four hours!!! Geeze, you've got to be kidding me - four hours battery life?? WTF????!!
Back to the drawing board: I rooted it and ran SetCPU with some power saving profiles. Removed the live wallpaper and went to stock wallpaper. Set display power off at 30 seconds. Note that 4G remains off since there's no 4G in my area..
Couple of questions:
1. Is there any way to toggle 2G/3G like there was on my old G1? I know that was a power saver.
2. I didn't stop to read all the documentation yet (typical male, I know) but is there any way to wake this thing up from sleep mode besides pressing the power button? I can see that power button breaking for as much use as it's getting from me constantly having to wake this thing up!
3. My brightness setting is set to auto - since the display is usually the biggest drain on these things, is there a recommended manual brightness setting (percentage) that seems to work well for you and saves on battery power?
I'm waiting for the Seideo Extended Battery (just like many of you) and am wondering if I should keep the Epic since I'm on the Sprint 30-day Easy Return program.
Appreciate hearing from everyone!

I don't have 4G where I am. But, I have a all black wallpaper(uses less power) and unrooted. I easily get about 12-18hr out of my phone wit normal use(text, talk, and surfing the net with skyfire). Only thing that really kills my battery are games(Robo Defense can take over 30min to play one game).
Thanks for the reply - situation NOT improving
Thanks for the reply.. unfortunately, the situation is not improving...
I tried setting a Sleep Profile using SetCPU that would under-clock the CPU (using the stock kernel) once the screen dimmed and the phone went into Sleep Mode. Unfortunately, as mentioned in another thread here, the result was that the phone froze and required a battery-pull to reset.
I'm really starting to lose my enthusiasm for this device; as beautiful a display and as responsive a CPU/GPU, all of that doesn't mean much if you don't have good power management built into the firmware. At 6PM this evening I pulled it off the charger at 67% charged, it's now 8:35 PM, only 2.5 hours later and I'm down to 22%. I'm in a decent coverage area and get 2-4 bars of 3G strength so I don't think it's an issue of the radio being the culprit; in-fact if you check the battery stats it reports that that lovely Display is accountable for 78% of the battery usage! So I guess we're paying a hefty price for these 4-inch AMOLED displays!
I read somewhere else that the most recent update (DI07) has caused the battery performance to decrease; since my unit is brand-new it immediately went and installed DI07 shortly after the first boot-up so I have nothing to compare it to.. can anyone comment on that?
Thanks!

I'm sure custom ROMs will put performance / battery life on the top of the list but until then, I use JuiceDefender beta and have seen pretty good results with it. It shuts off data whenever the screen is off and since my screen is off a good amount (only use my phone if I need to check email, call, and / or text, which is rare when I'm at work). Other than that, yes, use black wallpaper, lower brightness to the min. in the OS and browser, and don't leave apps that constantly use 3G open (things like ebuddy, pandora, etc.). 3G really destroys battery life so minimal use of 3G data would maximize battery life. Maybe the devs can figure out a way to get at least one full day of battery life on this phone. I'm hoping that is the case.
As to your post, yes, DI07 has resulted in poorer battery life, for whatever reason. I was definitely getting a few hours more with the older firmware. I would not lose hope yet. As disappointed as you are (and all of us are, I can assure you of that), the devs are really starting to push out nice ROMs already, and in a few weeks to a month, I bet we will see some solid battery life. Hell, even 2.2 should yield much better results. Patience
Thanks for the tip!

DI07 has hurt my battery life substantially. In fact, my battery drains very close to twice as fast now with the update. I don't understand what they did. My phone certainly doesn't seem any faster, my display is dimmer, and battery life sucks. I'm going to have to go back to DG27 so I can use my phone all day. With DI07 it always dies on me by mid afternoon. With DG27 it was still running by 11pm at night without even a battery low warning.
juice defender ftw
also, use advanced task killer with low security settings to kill all the background processes. Set the autokill to when the screen turns off. This keeps everything pretty well managed and helps with battery as well
JUICE DEFENDER BATTERY!!! Saved my phone from flying out of my car window at 10 in the morning........
here is a link to a thread I started.
Sharing my juice defender settings. I also use ultimate juice.
http://forum.ppcgeeks.com/sprint-epic-4g/133933-sharing-my-juice-defender-settings.html
I can get a day and a half (or slightly longer) out of a single charge.
YMMV.
Hope this helps
Advanced task killer + Juice Defender. You could also get some custom roms and Kernals that would help boost it.
But that's your best hope. Keep off 4g, wifi, bluetooth, etc.

Look here- try stopping the DRM service and see if that helps your battery life with D107

Ah, the evils of DRM can strike in unexpected ways...
I wasn't really having a battery problem but I just turned DRM off, so we'll see if battery life improves anyway.
I had a whole long post here that got wiped with the xda disk array failure, so I'll just sum that up here too:
1) Use wi-fi if possible - it REALLY helps
2) 4G does not seem to use the battery any more than 3G, although hunting for 4G does and 4G coverage is not as extensive as 3G even in 4G areas. So it's still best to leave it off if you're moving around.
3) Dim your screen and use a dark, static background. AMOLED screens don't work like LCD's; they use more power the more pixels are lit and the brighter they are.
4) GPS also kills your battery - leave that off unless you need it too.
I think that's it. I get about 18 hours on DI07 (even before trying the DRM thing; maybe I can get to a full day!).
One thing I'm noticing after checking DRM - I've got Google Maps' LocationService popping up about every 10 seconds, and I can't seem to shut it off permanently. (I went into Lattitude and turned that off, not sure what else to do.) That can't be helping... anyone know how to get rid of that?
I'm using juice defender and a constant email junkie, but lite use on other aspects of the phone. It goes off charger at 5:30 am and I'm about 67% at around 3p. It then goes in the car charger on the way home. This has much better battery life than the Pre or the Hero as with both I had to turn off email to get it to last throughout the day.
I don't expect these phones to last days, but I expect any phone that I get to last the business day. I've always been one to charge overnight.
Wifi drains battery more from what I've read.

I've heard the opposite that wifi (as long as it's connected) uses up less battery than 3g/4g. Any of them will suck the battery dry if they're searching, so make sure you have a connection to one of them.
Hi everyone, new to the forum. Just started checking it out when the Epic was released and this is my first post. Anyways, here's my question. My phone's been off the charger for 7 hours and 17 minutes and it is now down to 15%.
Display 79%
Cell standby 7%
Android System 4%
Phone idle 2%
Swype 2%
I've gone into the display settings and I thought I had set everything up optimally. The brightness is always very low. The screen timeout is 15 seconds and the keyboard matches that. I don't know what else I can do to cripple the phone to get the battery to last longer.
I have had wifi on, 4g off, bluetooth off, gps off. Really all I have done this afternoon while watching NFL games is check my yahoo fantasy score, play 2 games of WordFeud, and check twitter and facebook. I purchased Juice Defender a week ago and it has been running all day.
Any suggestions for how I can reduce the drain from the display? My background is a black and white picture of a friend of mine, which I thought would help.
Don't get me wrong, I love this phone. But the battery life I've seen is just terrible. I'd love to buy the extended battery from Seidio whenever its available, at least that would make it last longer even if the settings aren't tweaked.
Do you have juice defender installed?
Yep. Its installed and running now.

There are only two reasons for your display to be using that much battery:
a) it's too bright, or
b) you're using it a lot.
If you're using the phone a lot, your battery's going to run out pretty quick and there's no way around that. If you're using it a "normal" amount, which to me means maybe an hour *total* per day of having the display on, then the other culprit is going to be your brightness. (Some would argue that's less than a normal amount, but think about it... you get a new phone, you're going to play with it for a week or two until you've seen all the cool stuff. But at some point you're going to start putting it away most of the time and just using it when someone calls you, you get a message/email or maybe to play a game or two while waiting for the train.)
Set your brightness *all* the way down, just as a test for a couple days. Make sure all the "power saving" features of the display are turned *off* (auto brightness, and whatever that "picture detection" feature's called, I can't remember). You just want the display as dim as possible all the time, just to see what happens. See what the battery usage says after a day or two of this.
My bet is that you'll see a drop, and then as you get into a more normal usage pattern it'll drop further still. You can raise the brightness a couple ticks then as you learn how to stretch your battery out.
Personally, my display is rarely over 15% or so of my usage. Today it's 29%, but it's a Sunday and I don't have anything better to do but play around on my phone.
btw, it's still the first day I've tried this but that DRM thing might be working. It's almost 9PM and I'm still on like 80% battery, and like I said I have been using the phone off and on throughout the day.
That has helped tremendously. I installed it pretty much when I got the phone and I'm able to last the whole work day with 67% left. (10 hour day)
I have been letting a couple of days go by to see how the battery is and I have got to say that I am highly not impressed. I love the phone and even like Blur but the battery is really a let down. I know that the first day or so that I use the phone heavily because of course.. ITS NEW. But today I have been real busy at work and have maybe text a few people, made 2 calls, and looked up a number using google maps and my battery is now down to 60%. In battery manager, it says 5h 2m 25s since unplugged which would be me taking the phone off the charger this morning and heading to work. Other stats are:
Display 35% 29m 52s
Phone Idle 26% 4h 32m 47s
Voice Calls 24% 6m 45s
Cell Standby 11% 5h 4m 5s
Wi-Fi 6% 1h 51m 56s
From looking at these battery stats and usage, does it even seem correct to be at 60% battery? This is at the least very minimal usage for a phone.
Yet another battery thread... One thing before people start complaining: don't estimate battery life based on battery gauge! Complain once the battery is dead and you HAVE to charge. That's the real mileage you'll get from your battery (and give it a few days to calibrate). The gauge is not a good indicator.
I am a new Atrix user too and so far the battery life is 12hrs or less. Maybe that is not impressive. Coming from the N1, its alright in my book.
I do want to say to everyone complaining about the battery life:
It can take a week or more for the battery to settle into the routine and perform to its maximum ability. Lets start the conversation again later next week on where our battery is at.
Yesterday I got 13 hrs between unplugging the phone, and getting the 15% warning. Not all that bad. Not great, but definitely could be worse.
mine has yet to drop below 30% and im pretty much browsing the web and texting all day. I dont care what kind of phone you have but making voice calls and playing games/watching videos kills battery with a quickness no matter how big a battery you have. . The atrix in my personal usage is just as good as my ip4 was.
the atrix was very good on battery life compare to other android phones i've had
Have the Atrix and Epic 4G and the Atrix lasts easily twice as long as the Epic.
I have to keep he Epic pluged in for my hour comute with pandora, just to make sure I have enough battery to make it for the trip home. Normal usage during the day with brightness all the way down, wifi off, BT off, sync On.
Had the Atrix today (day one after full night charge, unpluged at 6:30a), kept BT On, WiFi On, Brightness 100%, Sync On, Exchange Sync On, Auto off/standby set to 15 minutes, Pandora on via BT for my hour trip (unpluged), forest Live Background, Weather Widget etc.,downloaded everyting I could think of/find, constant e-mail, and constant "whatsApp" till noon (lunch), wache YouTube Videos for my whole hour lunch (still full bright mind you). Created 10 minute Install Video with 720p for work, then uploaded via WiFi, not USB. More Texing, Calls and Downloads. .... FINALLY haed to plug it in at 2:30p, with 5% battery left, I think I could have made it till 3 for sure.
That's a full 8 hours of NonStop Use of everything. I expect to get Morning-Night life from normal usage.
Final word. Test it first. I did and it's Great, not just good. The receiving end of all my texts and e-mail blasting and video look ups has an iPhone. He had to charge his at 2:30 too, but has his iPhone set to max battery save (brightness 15%, wifi off, sync off, etc.) But was using as intensly as I was
... okay I'm done ...

Well I must have a bad battery or something then because I am not doing nearly half the stuff that you are doing and am now at 30%. Is there any special charging methods or anything that I should try to squeeze out a few more hours on this puppy?

may be you have several internet connected background service running behind the scene?
My attitude towards the battery is a mixed bag.
1) PRO: It blows away the battery for the Eris (which I'm coming from)
2) CON: As these phones come to be computers with phone capability, it's really time for manufacturers to try their hardest for better batteries. I'd eagerly accept a phone twice as thick as this one if it meant double the battery life.
I find mine is only good for 10 hours (much less with heavy usage, but low calling time). I expected more.

I really call bull on this.
Coming from the world of Airsoft, I'm no stranger to battery performance.
Most of these performance myths are hold overs from the Ni-Cad days and don't apply to modern batteries.
Call Bull all you want. But it was true to the N1 and so far its been true to my battery. It does not last the first few days and gets better after a few charge cycles.
Frankly, everyone believes whatever they want on batteries. I for one take it as a user by user experience. I watch my battery life a lot, but I also like to have Google Reader and Google Listen syncing.
I'm at 30% right now and 12 hours unplugged. What I wouldcall moderate use. Its not as good as my captivate on custom rom / kernel but its far from bad enough.for me to complain about

Andriod sucks the battery, bigger battery on Atrix didn't help much. Google need to optimize the OS for better battery management. I am disappointed coming from Samsung Focus & iPhone 4, both have superior battery life. BTW, I am on Day#4, conditioning the battery didn't help any so far..
Within Range
Looking at all the comments - I would say the Atrix is within range -- I knew when I saw the 1950 mAh (or whatever the exact spec) that the tegra processor must really be a power hog -- the new processor, along with the huge screen is going to draw a lot of power. Comparing to other phones with single core processors and screens even 20% smaller is not reasonable.
Definitely a good point... going to be interesting to see how well other dual core are going to hold up. That will be a better comparison.
Is that battery really a 1930mAH? The size looks like any 1500mAH battery isn't it?
I managed to get close to 16 hours of 'normal' use, meaning I wasn't trying to drain it, nor was I trying to conserve battery. I took the phone off the charger at 3pm and made it all the way to 2pm the following day with about 20% left. That's 23 hours, but I subtracted out the time the phone was on while I was asleep, 8 hours (nighttime mode).
Hmm hearing all these replies i believe i have a defective battery. I unplugged mine today at 5:15AM and now it's 2:18PM and it's just gave me the 15% beep. I've sent about 25 texts and played some words with friends. I've got watchdog installed and no apps seem to be out of control. I'm wondering if a factory reset would fix the issue or if i should return it.

try going to your dialer and entering *#*#INFO#*#*
Look under the battery usage and check the different items. Is anything using a significant amount? it could be a rogue app.
I will say MotoBlur has a lot running in the background. About twice as much as vanilla android.
I have turned most of this off and I do know that is helping my battery life.
I don't know if it's my imagination, but since the 2.4.6 update, my battery life has dropped a bit. By the time I get into my office from my morning commute, I'm anywhere in the 65-70% battery life after unplugging from a full charge. I haven't done anything new. I always unplug around 8:30 am when I head out, I do some light chatting with gf, browse some sites, check facebook (usually very briefly), and maybe sometimes do a little reading on my device. By the time I get into the office around 9:30 or 10 AM, I'm usually around the 80-85% area with battery.
Lately, doing the same thing, I'm seeing the aforementioned 65-70%.
Is anyone else experiencing decreased battery life since 2.3.6?
I'm on a Tmobile Nexus S, running stock 2.3.6 (no custom ROMs).
2.4.6 ? .... maybe 2.3.6 ... and yes, I also noticed a slight increase in power consuption after the upgrade. The stand-by is still great .. about 0.8 - 1% per hour.
Sorry, yes I meant 2.3.6.
Thanks for replying Ro_explorer. Is your increased power consumption significant? Seeing 65-70% when I'm used to seeing 80-85% as I get into my office, I find, is a large change. To be frank, the battery life of the Nexus S in general isn't so fantastic to begin with... this hit makes it worse.
Anyone else?
I used to get home with about 40-50% after a whole "normal day" (unplugged at 8AM, and getting back home at ~8PM) .. now (with the same average usage) I'm getting home with ~30-40% ... that why I said "slight increase" ...
Not your imagination, I too have noticed this. I hope the next update, will fix this - as I used to get pretty good battery life (even with over 250 apps).
When I recently updated to the 2.3.6, it caused a bug of continuous reboot (every 1-3 minutes), so I had to do a hard reset - now it works fine, but I only have added back about 15 apps - and the battery life sux!
Downgrade OS' it will be ok.
This is so weird. Why is the battery life worse?

You want bad battery life? Try an Evo 4g with a Sense rom. I averaged about 6hrs using a 1500mAh battery, in stock form.
The nexus is pretty light on power consumption, if you ask me. I average 15hrs on the stock 2.3.7 rom/kernel combo, with stock battery.

I'm on 2.3.6 and need to charge every two days. I text a lot and do light gaming. I'm typing this from my phone. Maybe you could drain the battery and wipe battery stats? I'm not even at 50% yet and I charged yesterday.

I also noticed that the battery last less time
I've been waiting to see if anybody else reporting this issue
i noticed a decent increase in battery life going to 2.3.7 and thought that previously the battery life had been fairly poor :\
I am non rooted, and get around 20 hrs on light to moderate use. Again. Stock, non rooted.
How do I recalibrate my battery? I wonder if it could be that...
There are many was to recalibrate. Some involve wiping batt stats, some plugging and unplugging phone several times after charge.
I have always found that using the battery almost all the way down, but not past 5%, and then full recharge conditions it very well.
Oh I've been here to solve the problem
"Why last 2 weeks my Nexus s drain battery so fast ? or I have to calibrate it"
Thank for your notice about update OS to 2.3.6.
I think that's a root cause for me too.
1. Could I rollback to 2.3.4 ,how?
2. Does battery calibration is useful for this case , how?( someone suggest to calibrate when flashing new rom )
Thank you very much..
i want to know who have some methods to do with this stuff

Whenever switching roms, kernels, or batteries, i always perform the following :
1. Charge to a true 100% (Battery Monitor Widget will register +0 to +2 mA)
2. Wipe battery stats using recovery (Amon RA has this option for the Evo, not sure about cwm), Battery Monitor Widget, or a dedicated app.
3. Discharge battery to 0% with normal usage. When the phone shuts down, I pull and re-install the battery and power back up (it will shutdown again very quickly).
4. Recharge battery and be on my merry way.

I found one workaround solution for this issue on
ww.google.com/support/forum/p/Google+Mobile/thread?tid=1684c50cea15282a&hl=en&fid=1684c50cea15282a0004af022e5ed212
Sproogle77 's solution
Problem solved. Using the OS Monitor app, I found that the main culprit was Google Services - the Contacts sync specifically. Even though I had this disabled (only Gmail was being allowed to sync) it was constantly working, apparently trying to fix a location. The message log showed that it was generating continuous debug messages, all about locations - around 10 of these every second.
I have solved the problem by disabling 'Use wireless networks' under the Locations & Security settings.'Use GPS satellites' is still running. This immediately dropped my CPU usage - which had been running around 30 to 40% even when otherwise idle, to around 10%. Google contacts sync is now using 0% of the CPU. The difference in battery life was pretty much immediate and is now back to what it was before - the change in the slope on the battery usage graph is remarkable!
This doesn't really seem like a solution to me, and I don't know whether other aspects of my functionality are being affected, but at least my phone is properly useable again.
I'm testing for 1 day and I think that's working for me.

One reason is that the new version of the stock kernel removed a speed stepping, so it'll power to higher levels faster, thus using more battery.

That actually isn't the problem. I'm using netarchy's kernel and still get this problem.
My battery life dropped from 16 hours --> 6 hours. the slope on my battery usage life is horrible the system is also awake almost constantly even when I'm not touching it / getting no messages.
I will try the fix suggested on the google support forum and see if that does the trick. sloppy update.
The Z3 is a nice device, I enjoy the screen, thinness and weight, but the latter two definitely come at the expense of battery life.
Of course the faster CPU also plays a part. I'm just getting 3 hours of on screen time with my usage out of it. On the Z2 I got 4 hours.
I don't even know what these people do who get an insane 10 hours of screen on time out of theirs. Probably different kind of use, but still...
Once again I need to look having an external battery with me.
Disappointed.

Post your battery stats page. Seems odd to me. I have 2.5 hours of on screen time with 10 hours on battery at 78% at the moment.
I noticed that too since I switch from Z2. Its difficult to see from the power management tool indicating how many screen time ect.. the battery life just don't seems to be better then z2, and results and very random.. sometimes better then z2, sometimes worst then z2. Perheps firmware upgrade will help..

I have rolled through 3 Z3s due to defects on my 4th, all had great battery life up to 8.5 hours SOT, lowest is about 5 hrs SOT, before calibration. Give it a few charging cycles, or do a full charge and full discharge then recharge and use. You should then be fine. If that does not work maybe you got some errant apps or lots of them continously syncing. Also go to backup and reset menu and disable data logging.
been averaging a day and a half with over 8 hrs SOT with mine. mix of wifi/lte
I don't know how you guys do it. I always get around 3 hours SOT, no matter what. I wish there was a way to check wakelocks without root.

I think it has something to do with the apps you use.
Facebook, facebook messenger, snapchat, swiftkey and Nova Launcher gave me from 4+ estimated days (in stamina mode) to 1 day and 1 hours.
If I don't play games, I get between 6 and 8 hours SOT at the moment.
Check that google play services aren't burning through battery.
Should never get 2 or 3 or even 4 hours SOT unless you're playing games.
I use screen brightness on about 80% as well.
I'll be posting my power usage screenshots soon.
Off to the top off my head, screen was about 50% of power (with automatic brightness, and the slider set on the 1st third), the most power hungry app took about 25%, with the rest taken up by various other processes and apps.
WiFi off.
Facebook used to be a battery killer, I don't use it, but check on that.
Z3 has an incredible battery life
there's something wrong in the op
For my baterry stay perfectly (often 20% for system 20% standby and 50% screen)
Even if it's Facebook that eats 25% of power that still wouldn't account for the overall bad battery life.
Nope mate, sorry - my battery life is out of this world. It's not the Z3, it's your device - get it tested, re-flashed or inspected if the problem persists.

Oh no I already removed, I do not have any battery issues, I was just giving a tip to OP.
Right, so here are my power usage screen shots.
I don't think these can be called ok in any kind of scenario.
I would like to add that with my Z2 I didn't ever get up to the 6 or 7 hours other people were getting out of it, but with my kind of use I got 4 to 4.5 hours, which is considerably more than I'm getting right now.
I supposed it's kinda obvious, with a faster CPU and a smaller battery. What else could have happened. It just annoys me that Sony tries to tell us that battery life is BETTER than on the Z2. It is not.
Well, reviews uphold/confirm Sony's claims so its probably not the phone itself per say. I get 7-8.5 Hrs SOT easily. Disable autosync when un-needed and location services as well. Then see.
Just as everyone suspected, it's malwarebook causing abysmal battery life. Remove it and watch your phone get tons more battery.
Considering that you're one of the very few, if not only, getting poor battery.....I have no idea what else it could be. The phone get's better battery because of using the 801 SOC instead of the 800, which sips battery like fine wine, leading to the increase in life over the z2.
Malware.... Yeah, whatevs.
Fact remains that with the same usage as before my Z3 performs worse than my Z2, so there.
So Doze is supposed to minimize battery drain to almost nothing overnight or when the phone is not in use for a long time. How many people have actually experienced that? I'm not sure what to think, I lose about 1% per hour consistently overnight. That's without greenify or other battery saver methods. But it still seems excessive to me for such a hyped feature. I wonder if future hacks will be able to turn doze on in 1/2 hour instead of 1 hour. What have your experiences been?
1% per hour is pretty good. That means your phone would stay on for up to 100hrs which is more than 5 days. Are you complaining about that?

That is pretty bad if Doze is on given that 1%/hr is a widely accepted standard pre-marshmallow

Doze only dozes applications from waking up the phone at their will, but still does periodic wakes. It will only make a big difference really if you had a misbehaving app in the first place.
Don't forget that even in the best case that Doze stops all activity from apps, you are still using power connected to the cell and or Wi-Fi, plus power to refresh the memory and other peripheral chips, so 1% an hour could be considered quite good.
Try putting the phone into flight mode over night and see if that 1% drain an hour goes, if all is well you should get around 1 or 2% power loss in 8 hours.
The other think to note is apps can bypass Doze and schedule wakeups regardless, this needs an update to the app for Marshmellow. So if you had an app that wanted to wake the phone every 10 minutes to download the latest adverts, it will stop under Marshmellow when Doze kicks in, but they could update their app to use a different API call and go back to waking the device every 10 minutes bypassing Doze. I strongly suspect that the Google Play store will start recognizing this API call and may start warning about apps that are battery drains, so the user can make a better decision, otherwise Doze will have a short term benefit as apps work around it.

Doze is working really well for me. Battery drain overnight seems to almost be non existent. I went to bed with 51% battery life on my phone. I woke up roughly 7 hours later and it was still at 51%.

Yeah I had only 4% drain after 8 hours overnight.

that was a great explanation, also I do think 1% per hour is bad since like someone already stated that I've had phones that would drain about that without marshmallow. Also those other people who replied I would really like to know how you get such little battery drain, do you guys have a lot of apps installed? I unplugged today around 5 am and woke up around 10 am with 95%. I have about 60 apps and 3 email accounts (1 yahoo which is set to sync manually).
Personally I am trying to sort my battery issues with this phone as some are getting great battery life (5 hours sot with over 24 hours off charge) while others are barely hitting 3 hours like me. Also I would think doze would be better than what I am experiencing.
How long have you had the phone for? AFAIK it can take a few days for Doze to "learn" how to optimize (reduce) battery drain. You may find it gets better over the course of a week or so. If you check the "detailed" battery stats (click the first battery graph) you should see little to no "awake" time overnight when you'd expect Doze to kick in - e.g see this link as an example: https://drive.google.com/open?id=1wjguaIIcGgUZn7w-KXnY3MJ0qTK0rUCWiA
Otherwise try as @PhilipL suggested and run in aeroplane mode overnight.
Doze is working as advertised here. On my 5x and my N5 as well.

It could be your location and the cell signal you are receiving, sometimes even if you have a good signal you still might be evenly served by 2 or 3 masts and the phone keeps swapping between them, if you don't have too good a cell signal, the phone will be using more power during standby. The only way to tell for sure is to put the phone into flight mode overnight.
One thing to note, you will only get the maximum screen on time if you use your phone a lot, i.e. all the screen on time is used during a 12 hour day after a full charge. If you are only using say 30 minutes one day, 20 minutes the next and so on, your total on screen time achieved will be less than many are saying they get, this is because more power is spent over time on background tasks and syncing, leaving less for actual on screen time. My previous Nexus 5 for example, sometimes I would go 4 days without needing to charge it, but my actual on screen time was only an hour or so.
Perhaps crudely speaking, 1 day of very light usage may see enough battery power expended on back ground tasks to see 1 hour sacrificed of on screen time.
Usually it doesn't matter how many apps you have installed, that in itself doesn't use any battery, of course if those apps are constantly pinging back home to some server, then that is how power is used. Doze will be helping with those apps over night and other quiet periods.

Thats the thing I get about 2.5 hours sot in about 12-14 hours and have to recharge before the night is over. Of course quick charge helps but I really don't want to rely on something like that. Also I'm wondering if wifi calling on will help with battery or will it be like the iphone where it'll just drain more battery? Gonna have to play with it and see what I can improve on. Also noticed that chrome has been using about 15-25% battery on any given day. I do use it as my main browser but that still seems excessive so may try a different chrome iteration if it keeps up.
Thank you to everyone that has helped and hopefully this can be a come all thread for people with questions about or problems with Doze.

I'm getting 3 to 4% drain during 7 hours overnight, working well for me.

Did a test last night, charged the phone to 100%, put it into flight mode and went to bed, checked it this morning and still at 100%.

Now you need to find what is draining your battery overnight when not in Flight mode. I suspect you will find either Google Services or Google Play services not releasing the modem or something similar.
When I installed Cerebus it asked to turn off battery optimization. My guess is that is Doze could be wrong though. It was the only app that asked. So far battery life is better then the N6 that I had a Amplify running on.

Might be a standard if everything worked perfectly, which I have yet to see. With this new architecture, you are guaranteed it. I love it.
I lost about 1% in 3 hours last night with WiFi calling on. Maybe it has to do with poor coverage. Last night I did end up with 3.5 hours sot which I think was my highest. So in the past few days I have factory reset and turned on WiFi calling.
Now I need to optimize my browser usage, chrome was talking more than screen was ~20%. Using #nochromo now and not much better.
Battery went from 66 to 64% last night in 8 hours.. #dozeisdope
