Well I've been running android for a while now and I have tried a lot of things to try to extend the battery life. From the advance task killer to changing settings with the screen. So far the battery only lasts about 4 or 5 hours on stand by. Anyone has any tis to help me optimize the battery?
Get rid of the task killer for starters!

4 to 5 hours?
Does Your mobile go into sleep mode? (constant green light) or does it keep blinking green or is it constant orange?
Turn GPS and Wifi off..?
I have a Rhod100 and nowadays my battery lasts almost 2 days with synchronising and 3g on. GPS and Wifi are off, unless I need them.
Perhaps the battery isn`t that good anymore like said before, or try to get the phone in proper sleep mode with constant green light.

FYI blinkengreen is only available in the WisTilt2 test kernels.
However - with those kernels and taking measures to avoid wakelocks, you should be able to get MUCH better battery life.
As to task killers - I disagree on getting rid of these. They are necessary if you have any "must-have" apps that like to wakelock our phones. (Like Facebook) - you have to be careful about what you kill though.
Also, you need to disable GPS if you want the phone to enter deep sleep. Something deep in the kernel RPC code wakelocks permanently when the GPS is enabled, even when not actually doing anything.

FYI, last time I checked Wifi power down wasn't actually implemented yet, which means that once you power on Wifi, it actually stays on forever, and when you shut it off in Android, it just disables it in Android, not powering down the hardware.

Ahhhhhh...that explains why I don't get fantastic battery life like some of you...I use wifi quite a bit at home as my 3G signal is not great...I make sure and turn it off as soon as I am done with it but I've always felt like my battery drain is greater than it should be...there's the answer as to why...

I don't think so..
I have my wifi work many times and i can have at least one day long using on my rhod 100
Well if you guys read the log, the wlan only pulls like 3ma idle. So even tho it does stay on, it doesn't drain that much in reality - the fact is it does drain more, but it's relatively insignificant.
Not that the bug shouldn't be fixed, just that the bug won't cause the battery to drain that much faster.
The thing that greatest increased my battery life was getting a simple free data toggle widget. If you really aren't using it all the time you might as well turn it off. You can still text and call with data off. You'd be surprised at how much android wants to use data with things you don't know about. I always check my data by calling *DATA# on AT&T and for some reason it uses way more data than winmo does on a daily basis. (Some of you guys probably know why and have a simple explanation for this, but I don't )

Yea, Android is chatty. Lots of things sync in the background, and depending on the apps you use... Typically an Android device is going to use significantly more data than WinMo.

Interesting... I have a 200 mb limit on my data so I really have to watch that, I knock out two birds with one stone with the data toggle widget i guess. Increased battery life and not going over my data limit. I believe even native android devices have trouble with battery life. Some of my friends with the evo's and epic 4G's almost run out by the end of the day.
A lot of that chattiness is BS that you can't even disable when you turn off all auto-sync options in every app. That's why I use Droidwall, to control exactly which apps get to use the network.
I also use an autostart manager to try to eliminate unnecessary apps at boot time, but I haven't found a good one yet. This oughta be builtin to Android, not a 3rd party app. Annoying as all hell that there's no direct control of background startups.
The other app that usually keeps my phone awake is geniewidget. I should just uninstall it or something, it's way too poorly behaved.

This is the one I have currently https://market.android.com/details?id=com.rs.autorun&feature=search_result
I don't trust it though; I had an earlier version of it and it seems the developer made it self-destruct, then released a newer version with ads and other crap. (Fortunately with Droidwall I don't have to see this thing's ads.) Most likely in the future I'll just write a shell script that issues the pm commands that these things are just a GUI wrapper for. I really detest developers who try to make money off of trivial code.
DroidWall is on the Market, but here is its original thread

I have been messing around with system tuner app for a while now and I really like the program.
I would like to hear from people who have used this app and their results with various tweaks that this app provides.
in the boot settings menu:
1. forcing both CPU's online: this should technically give you a better battery life, since it puts less strain on on cpu at a time, has anyone had a good exprience using this?
2. Boost app loading: anyone had any significant improvement with this?
My own settings:
I usually clock my phone at 1.5 (on demand governor) even though faux's kernel allows 1.7 max. I put max clock for screen off at 384 and conservative governor.
I have Undervolted before but do not see a very significant battery difference so I just left it alone.
I tried out the autokill option of system tuner, I only tried to kill the ghost apps, to refrain from the cpu from having to keep restarting the phone, but this also seems to kill battery life...In my experience any type of task killer however detailed will reduce battery and does not increase performance, unless you're running a poorly written app that just needs to be killed.
I use three other programs to monitor my phone
1. system pannel: very good at finding rogue apps that kill cpu...I highly recommend the pro version, you can get a history of what has used cpu up to a week.
2. Onavo and My data manger which basically monitor my wifi and mobile traffic, Onavo only monitors mobile network traffic and lets you restrict apps to only wifi. however it does not measure wifi use of data. My data manager monitor both wifi and network usage but does not give you any options to do anything with the apps, it basically tells you what program is using data while on wifi and mobile.
If anyone has found a good balance between performance and battery saving, please do share.
Thank you.
I read some other guy also mentioned the all cpus on thing. im not sure but isnt it the same as making both processors work at the same time which leads to phone overheating? I will give it a try though. from what you noticed, do you like it more with both cpu on or is better the way it was?

will see then. hey seansk do you notice some kind of hesitation when trying to unlock the phone? when u press the unlock button at the top. I think that boost app loading thing causes this cuz when have it enabled the unlock button you have to press it twice to work, while when disabling that boost app loading thing all works fine...

I have widget locker and havn't had that problem...I just flashed faux's latest kernel and am in the process of re calibrating my battery, it seemed to jump from 100 to 90 in about 10 minutes!!!!!! now I noticed that happening...but I havn't had time to fully replicate it...i need more time..I believe it might have something to do with fauxes kernel, he mentioned that when screen goes off he it puts the phone into a low power consumption mode, but also has something that when you turn it on, is quick to turn on!!! we'll have to wait and see.
If you've been following this thread, just wanted make a quick update...I want to give you my results with system tuner tweaking. Forcing both cores online is a bad idea. It will literally kill your battery in a matter of a couple of hours. ICS will hopefully be different and utilize the cores how they should be, saving some battery and giving the amaze longer battery life!
On the other hand reducing reducing clock frequency on screen off will help in battery life (obviously).

yes still stock rooted, I put the governor on conservative and put the frequency to 384 or around there, while screen is off.
What helps most I found out is turning off all the radios like wifi and network data, (basically putting phone on airplane mode). Instead of dropping down 15 percent in 6 hours it drops like 3 when I turn airplane on. But like I've said before it's unrealistic I'm always recieving google talk, google voice, facebook updates and I have to have both of these on which unfortunately eats a lot of battery.
I keep switching back and forth between faux's kernel and stock and I'm actually finding stock gives me better battery life for some reason. Even though I set the clock speeds on both at 1.5 ghz.

Battery Life
Major battery drain is the screen, when on eats up all the juice, dimming helps a bit
charge source: usb vs AC charge
usb charging takes quite a while, AC charge quicker (~ an hour)
Also, from my observation, usb charged battery runs out quicker than AC charge
Data Connection, Juice defender helps a lot
turn off sync you don't need, like HTC sense

well the problem is its not my screen. It's when the phone is idle, I usually lose about 15 to 20 percent over night. if I turn off the radios it drops down to about 3 to 4 percent overnight....like I said before I can't turn off the radios...I constantly use google voice, google talk, facebook. And they require both a cell connection and a data connection. I hate to pay for more apps...I've already paid for a bunch of apps to control and see my phone's usage of cpu and battery...is the app really worth it? wish they had a lite version

I have juicedefender ultimate, used it for a while actually...the only good use of it is turns off radios all other things when screen is off..all other things are negligible to battery life...I currently don't use it anymore. I tried multiple things/tweaks with it for about two weeks,...NO point lol...I want to be able to get my google talk message and my google voice texts, it annoyed the hell out of me when someone had sent something like 2 hours before and I would just get it when I woke my phone!!! I tried all kinds of things...but the only thing that actually worked was turning off radios during screen off which I don't want...I can't win lol....I can't have my cake and eat it too!!

while you sleep, you won't be checking for emails will you? but you expect to wake and see emails received.... that is where it comes in handy. with apps like tasker, you can automate some of this activities. tasker + syncer should be a good combo for you.

For what it is worth I am running BulletProof 2.3.1 and last night I took phone off charger at 10:00 PM, alarm goes off at 3:30 snoozing every 15 min until 4:15...Battery was at 100% still. It is now 7:00 AM and battery is at 96%.
This was after flashing back to BP around 8:00 PM.
I've noticed the same type of activity when in Airplane mode. Extremely low power consumption - fantastic.
Is it possible maybe to undervolt the Wifi/BT/Mobile radios? Would that make any difference or am I off base here?

You had something setup wrong then I think.. you can change how often in syncs while the screen is off, the default setting is for it to turn on data for 1 minute every 15 minutes. Most people don't need to know things so bad that they can't work with a 14 minute delay(at worst), and of couse the internet is on while screen is on, when you're actually using it.
I thought I would need to use juice defender, but since I switched to bulletproof, my usage last me an entire day. From 8am till 1am, usually with some to spare. The only tweak I made to cpu was to enable 192mhz, it isn't like there is a performance drop, but it did make a notable difference in battery life.
If I wanted to I could use juice defender to get more than one day out of it, and I keep a spare battery on me in case I really need to use the phone.. but haven't really needed it.

How many apps have you installed?
Hi All, I have been using the Xda for long time and I am a bit greed and I never register, yep that's right, hate plz come.
But anyway, I have used too many phones that I can't even remember.
Last couples of week, I got rid off my Nexus one and got A Razr, but the disparagement start right with the battery life!
First a few days, I was using only wifi, as one of my number does not has Web pack on it, and I notice a horrible battery performance on the device and I am
Later on, I activied my internet on phone and here comes my theory.
I notice the Wifi is always running for some reason on the background even if I set it as turn of when screen off, when I check the battery usage, it shows almost every second that wifi is on. That should not be right, it should turn it self off when screen off, and it is not doing that.
Second of all, later on, I noticed something like *WIFI* shows under battery usage, and I was thinking what the heck is that, cause there is another "WIFI" still showing, and also something called" .com.motorola.contact. something like that is waking the phone and using the wifi as well.
And there also something like"motorola.home" running and using wifi for ages. Very strange.
OK, then I went out today, yes, I most of the time stay @ home, na I am joking..
I am mostly in a place with WIFI, home, work place, and Uni. All wifi here and there. Today, I took train 3 hrs total out and back from Birmingham to London for those who like stories. it was 1:30 afternoon battery @ 80% then I listen to music for 1 hr and use whatsapp quite a bit(battery hunger app even on iOS)
On the way back I played GTA 3 for one good hour. and it is now 9PM, and 15% left, as later on I tweet a bit, web a bit. which is good, also I took underground so signal is not always there.
After all these my question is for those who had the battery drain, are U in a wifi enviornment quite a bit time and use wifi?
If so, set the wifi sleep policy to Never(this actually will help) and while not using wifi to use heavy data stuff, turn it OFF and see what happen.
Also turn off GPS espically if you have facebook on phone and also the using wirelsess connection for location, turn that off as well.
BTW the GPS on Razr is reallllllly fast on location, it took 5 second to find me from cold boot. Awesome.
And I don't use task killer or smart action, I think using sensor and active these sensor to save battery while they are using a lot juice is not so smart.
BTW: due to I am on and off subway, my iPhone4s dropped a good 15% without any use, it just sitting in my pocket. (as for now, Android is the fun bit, iOS is the backup, as it does hold battery better a bit...lol)
I am on 2.3.6 (651.167.19.XT910.retail.en.EU)
I flash the rom couple of times, it all shows me WIFI is doing some strange thing.
Today still draining and I use a data usage checker and find that moto blur is using a hug a mount of data, WTF!?
I find battery performance vastly better on wifi than 3G. Mine has had atrociously bad battery life recently, so I'm backtracking through stock ROMs to see if I can replicate the setup I got 5+ hours of screen-on time with.
Gotta love those updates. The sooner data works properly in custom ICS ROMs for the XT912, the better.

Sent from my XT910 using XDA App
I've been using SetCPU to create profiles on the ondemand governor and extrapolating from my general usage during commute, news/texts/im, fair amount of screen on time, I'm getting around 10% drain per hour which is fairly nice. With screen off and 3g running leaving the phone to idle, it drops to around 3-4% per hour which is significantly better from what I was getting right out of the box.
Battery test for Motorola RAZR XT910
Yesterday I decided to do a simple test with my new smartphone, a Motorola RAZR, I shall not charge until he get just 15% of battery remaining. So here I will put the results and thoughts about it.
8:00 AM: I woke up and took XT910 off the charger. Wi-fi was turned on;
8:00 - 9:00 AM: I passed one hour using Pulse to read some news, once or twice I shared some news in the Twitter and Facebook, with the Wi-fi on, of course. The Battery got 85%;
9:00 - 10:00 AM: I started to use Whatsapp to chat with a buddy, took at least 45 minutes of intensive use, battery got 70%;
10:00 - 11:00 AM: Cellphone in stand-by, BUT with the wi-fi on, waiting for someone, battery got 60% yet!;
11:00 - 12:00 AM: That one appeared, so I used Whatsapp again for 30 minutes, and battery got 50%;
12:00 AM - 2:00 PM: Two hours with the cells blocked, but still with wireless connection, 40%;
2:00 PM – 4:00 PM: Motorola in stand-by, now with the wi-fi turned off, so, in the first hour, he keep 40% and in the second, he got 30%;
4:00 PM – 5:15 PM: The final test, I passed just one hour playing Ceramic Destroyer without stopping, the battery got 15% and then the phone asked for charging!;
Well, the battery last for 8 hours with wi-fi turned on almost all time, so I think it's was fair, BUT, the battery status is a bit fake, I don't think that the information was correct, but, it works when is a simple test, you know, right?
We all know about the 1,2 Ghz processor, this drains a lot of battery, but the real villain is the connection, wi-fi or 3G, they both spend so much energy of the cel.
My last thought is... always charge your phone when it's possible, even if you don't use in an intensive form, I hope that you'll not have problems because a low-batterys cell phone.
One thing I've found is that when my battery is draining like a tub it's has nothing to do with any data connection. In running apps there's a media process that keeps my phone running at full bore. If I just kill that I get dramatically better battery life. Normally when I don't have to deal with that I can last all day with a quick touch up charge during the middle of the day. This on my xt912.

One thing I've found is that when my battery is draining like a tub it's has nothing to do with any data connection. In running apps there's a media process that keeps my phone running at full bore. If I just kill that I get dramatically better battery life. Normally when I don't have to deal with that I can last all day with a quick touch up charge during the middle of the day. This on my xt912.

your right, certain apps can affect battery life so it is ok to kill running task. however just want to make sure other users know that using task killer to constantly kill many apps is not a good idea! most of the apps will prob restart and this cycle will only drain your battery more. whatsapp is a good example, even they state on their homepage you should remove from task killing as battery would drain not just from the constant restart of the app but also the fact that it would continue to regain connection to their server whenever it restarts.
try use a dark colour like black as you know white colour drains much more battery. if your a constant user of google (maybe even if its your homepage too) try use the black google version. save some battery.
i think personally for me 3g uses more battery than wifi. another factor is the network bars that drains battery if low as constantly hanging onto that low connection.
you should try flight mode and see how the battery fairs there so you can get a rough idea.
also come across an app called FreshNetwork which is a signal booster & finder. Android Market - 4.7 out of 5 Star overall rating! (9,152) as i speak, and it does work.. theres been times where ive had 1 bar connections but after using it i get like 3/4bars. so it helps ease the battery drain there as connection is much better.
hope its of some help guys!!
I know theres is some apps that drains battery, one tip is just deactive the auto-sync with your accounts, other thing, I want a batterystatus app, to know better that stuff.
And I will try this connection app, thanks

Man I even turned off my smart actions, so far I only turn on things when I am really using them. Auto-sync only with wifi!

Its something stock with the phone. I just got a second and it still does it. I haven't figured out what starts it. But once I kill it, like I said my battery life is fantastic.

hey first of all nice site secondly your tips are pretty much on the dot.. just thought of these apps people might find useful
autostarts - helps with disabling apps from auto starting when phone boots up (may be slightly speed up boot?) & also prevent certain app event triggers (maybe an app permission u aint happy with?)
FreshNetwork - helps locate better signals in which in return would improve battery life

In running processes, the vague media process. Auto starts and kills battery quickly.

what are others thoughts on some of the pros and cons of this update? i'm thinking it will actually save battery to have wifi 'always on' in standby mode rather than repeatedly switching between a on/off state which uses more energy.
It will definitely eat more battery if it's always on under the lockscreen...
Also there is an option to deactivate notifications when new wifi hotspots are around.. if you are about battery life you should deactivate this..

I keep my Wifi always on because it consumes the least battery (vs 3G, LTE, etc).
If I don't play games on my Lumia 920 the battery can last 3 days.
This update is freezing my phone Dunno why but I have tested it. I occasionally get a freeze now and then, but when the keep wifi is on, it is like every couple of hrs... Will test it more though.

Wrong unless your phone is using 5-year old wifi chip.
Correct me if I am wrong, but is the wifi on this phone an on demand type system? From what I see on mine, the wifi unless being used for an actual update or downloading other content goes to sleep when the lock screen is on. It then wakes up if there is an update pushed to it or if something else needs it or of course if you unlock the phone. At least that is the way it appears that mine works.
Also your radio service are going to use much more power than the wifi will as they are higher power transmitters and receivers. There is a reason wifi only works within a few hundred feet and radio works for several miles that is due to the power difference. Of course with more power you get more battery consumption.
In the case of conserving the battery you are better off to use wifi when possible, leave it on and let the phone control it.
In my experience keeping Wifi on permanently lead to a remarkable decrease in battery life. That will depend on where you are though. If I have it sitting at home where it has Wifi connectivity it's likely that I would see better battery life because all actual transfers will happen via Wifi. At work though it can't connect to the Wifi network (private phone, work network) and so I have 3G running anyway while the phone keeps looking for Wifi networks to connect to.
The problem boils down to the fact that while you can switch off Wifi completely because everything can still work using 3G you can't switch off the phone part completely because only data is done over Wifi but you still need the mobile connection to receive calls/SMS.
I would suggest to anyone to simply try out what works better for them. For me it worked best to let Wifi deactivate automatically as it had been the default in WP since WP7 came out.

Maybe Wifi is using less power when you are downloading something and need a lot of data... But when your phone is idle... Constant on Wifi is using far more battery power than 3G that checks for email or weather every 1-2 hours...
Simple enough...if you are consistently in an area with a WiFi signal, leave WiFi "always on"...it will consume less battery. If you're in an area without WiFi signal then turn it off, as searching for a signal will help run your battery down.

Again, simply not true unless you are using a 5-year old phone. Even if you are in an area that has no wifi connection, the extra drain caused by searching for Wi-Fi networks is minimum in a modern OS and modern chipset. I have left all my android phones (the ones that offer Wi-Fi always on feature for a few years now) wifi on all the time. Never have felt much difference vs if I turn wifi off. It annoys me that WP didn't offer this capability for so long.

I tested a lot of phones Android and WP, my experience is that wifi always on is a battery killer... And I'm talking about state of the art hardware... It's just my 2 cent's but i keep it off...
When I don't charge overnight and wifi is always on my battery drops about 40%
with only 3G on about 8-10%
Foxbat: you can leave it any way you want to do it. I'm not saying Microsoft should remove the feature. But in my experience keeping Wifi on kills the battery faster. I tested it for my use case with always on and with Auto and in the end: Auto it was for me.
The best advice you can give to people is: try it out yourself and you will see what works best for you.
A picture or two says it all. See the attached files for my two testing: one with wifi always on for 24-hour and one with Wi-Fi in auto mode for 24-hour:
The right picture shows 0.0%/hour under current discharge rate... pretty impressive

The keyword is 'Current' -- means at that moment. You can derive the same thing from the left in various sections. The key here is that I don't see any discernible difference. Certainly not a battery killer in any sense as you claimed.
If you look at the first 12-hour period of both chart (when the phone is mostly sleep and not used), the result is almost identical. FYI, there are three push emails connected all the time: Hotmail, GMail and Corporate Exchange Email.
Yes the keyword 'Current' -- means at that moment... so your phone is not discharging although your screen is on... Very accurate app...

So, what you saying is that if you have the screen on, you will see your battery percentage drop immediately? You should return your phone if that is the case.
Battery app get its information from the phone OS reporting. If the OS reported the same battery percentage over a short period of time, the discharge rate won't be anything other than zero. That's limitation of the platform, not app.
Instead of criticize the app which is not the point of the post, why don't you post your findings where leave Wi-Fi always on kills your battery?
it' % per hour... and your phone is using currently using 0,0% per hour so if you leave it like that it will run for ever... so where is the mistake?

% per hour is a unit of measurement. It doesn't mean you have to take one hour to measure it in order to claim its rate. That will be average rate on that hour, not current rate which is meant to see what your current usage pattern is. It can't be used to predict your battery life. If you notice that when you take your phone off the charger, it will stay on 100% for quite some time before it starts to drop. Does that mean your phone battery can last forever? Think about it before post these ridiculous statements.
Foxbat - you are trying to tell us how our devices should behave while we are telling you how they actually behave in the real world out there. You can repeat your 5 years story as often as you want to but it clearly doesn't live up to the factual reality we experience every day and I guess after trying it out with different ROMs on the 920 and leaving all other settings the same I know the effect it had pretty well.
Nice to know though that you are having a different experience with different devices.
Is there any way to prevent this banner (picture attached) from appearing when Wi-Fi is initially connected? I use Juice Defender to disable Wi-Fi when the screen is off and it is very annoying to have this pop up every time I unlock the phone.
Every time you unlock the phone? Mine only does that on actual connects and thats it. You must have it set to turn off wifi during sleep? If that is the case... some dev will have to find where that is burried at in the OS. Easier thing to do is let it stay connected. Better on your data anyway and if youre on unlimited still why bother with wifi at that point?

I purposely use Juice Defender to turn off data and Wi-Fi when the screen is off. Both turn back on when the phone is unlocked, which is why it appears every time.
ahhh on rooted phones with custom roms i don't recommend Juice Defender. It's usually more trouble then it's worth and more times then not ppl say it uses more resources then it saves (battery). And why data when screen is off? Just curious since you'll only ever get just texts and calls then and miss everything else notification wise.
My guess for what you're asking for is someone would have to make a special effort to do it.

I would suspect that this may be doing more harm than good for your battery life. My battery will last much longer using wifi if available. Maybe instead of using Juice defender to turn off wifi, you could try using the "wifi off during sleep" option that is built into the phone. I think it will accomplish the same thing and it may disable the pop-up within the system.

I noticed that sometime with this phone (and the S3). "Off" doesn't seem to mean "off" anymore. My phone could mysteriously discover a known wifi network and suggest connecting to it while the wifi is supposedly turned off. If it is truely off, then it wouldn't know there is a network available!

I find that turning data off too dramatically reduces standby drain. It automatically turns back on if an MMS comes in and periodically turns on to receive other notifications. Juice Defender has worked pretty well for me and I'm on CleanROM.
I'm on CleanROM (1.0 still) with no apps to help with battery and i get .25% battery drain while idle (so thats 4 hours before i lose 1%) and 10-11% battery drain per 1:30 min movie with full brightness with WiFi on. How much better can the battery get on a stock battery? I bet you with Juice Defender you don't even get close to that simply because it actually has to run in the background while phone is idle to do it's job.

Without Juice Defender I'd lose 1% every hour and a half on standby. Since installing it, it has been much better.
After flashed Android 6.0 I noticed worse battery life than with 5.1.1
Looking for a culprit I noticed in the battery status chart that wifi is always on. It is a solid line with no interruptions anywhere.
This did not happen before. Thinking about a bad app, I factory reset the tablet and did not install any third-party app.
Even in this pristine conditions wifi is always on.
Do you have the same problem?
Thanks!
I definitely do not have the problem. In fact I have the opposite problem. I used to have twitter setup on my tablet (just for news sites like AP, etc.) and then used pushbullet to notify me on my PC/other devices. Since I flashed 6.0 once it goes into doze I stop getting those notifications until I turn it on again.
Last night I put the tablet down around 1am at 86% and this morning at 7:30am it was at 84%
Thanks. If you click on the chart on the battery section of the settings, what do you see? I see a solid uninterrupted line for WiFi, and interrupted lines for Awake and Screen On.

Yep my Wi-Fi line is solid because I dont travel with it so its always connected to Wi-Fi. Doesnt drain the battery at all really

Was away for 3 hours and when I came back home my Nexus 9 had turned off wifi. So it seems it works but it takes a lot longer before it turns off wifi. Used to be 15 minutes but what it is now I don't know.
Edit: tested it now, it's now 30 minutes before it turns off wifi.

I read over on the Nexus 5 forum that there was a wifi always on scanning bug going around that people with curing by disabling WiFi scanning under location services. I'm happy to say, after flashing fresh factory images, my 9 and 5 are working flawlessly. Like someone posted above, both of my devices left all night and half the next day only knocked a few percent off the battery. I usually charge my Nexus 5 halfway through the day, but yesterday I did not and had 40% when I put it on charge going to bed. My wife took the OTA as opposed to flashing fresh on her Nexus 5, but she has had no issues either.
I'm loving this update on both of my devices so far. The animations are so much smoother.

Actually after the first day or so it got much better. They are still delayed but if thats the tradeoff for the insane standby time I'm ok with it.
Here are my N9's current battery stats:
Tablet Idle Time (i.e. time off charger): 2d 4h 40m
Screen on time: 1h 17m
Battery Percentage: 74%!!!
I use my tablet to cast shows and did some light browsing/PDF reading (trying to figure out how to get my son to sleep ) so thats why the low SOT. Normally probably without even touching the tablet I'd already be sub 50%
I believe the WiFi always on showing under battery life is a bug. My n6 is the same way. Recently went on a trip with no access to WiFi. Turned WiFi off but yet it still shows it's always on under battery. I don't notice any additional battery usage so I assume it is just a bug and hopefully will be fixed in the next update. I believe the bug was also present in the developer previews
