Let me preface this by saying I'm not complaning about battery life as 36h is very good. That said, I feel like my phone is awake much longer that it should be. Anyone have any ideas why my Awake time is so much higher than my Screen-on time?
Once again, I'm not complaining but considering my phone was awake almost 5x longer than the screen was on, I feel like I could squeeze some more life out of the phone. I had 1 exchange account @ 15min, 1 gmail on push, no talk/g+, ~2-3 hours off wifi (4g), gps on, bluetooth off, 4.0.4, leanKernel.
When analyzing the wakelocks, I don't see anything that would explain almost 6 hours of extra awake time:
Considering most of this charge I was on wifi, I think I should have been able to achieve more than 1.5h screen-on time. Especially when I see people getting 4-5+ hours on theirs. What could be causing this seemingly excess awake time?
Since those screen shots, I've done another full cycle and here are my results. Same settings as before. It looks as if I did a bit better with the ratio of awake vs screen on, but I still only got ~20 hours. I'll admit, this had much more 4g time and heavier usage.
As you can see it's better, as it was only awake about 3x as much as the screen. You can see where I was at home in the second screenshot (The long bar of wi-fi) and that included me sleeping yet it shows that the phone was consistantly waking up overnight without any usage. Short of "email", I'm not sure what could be causing it. I got MAYBE 3 e-mails overnight.

Location services was NOT disabled in either set of screenshots. Disabled it and charging now. Maybe that will help?
Have you checked out your wakelocks using BetterBatteryStats (found here on XDA)? Also, download CPU Spy from the market and check how long your phone is in what state. If it isn't in deep sleep too often, you might have an app or service keeping your phone awake. Background Data of any kind usually does that. Also, the first culprit I would investigate is Google Maps. Uninstall that bad boy and test your phone out. I am betting you that 60% of the time, the problem with your phone being awake too often is with Maps running unnecessarily in the background. And to be clear, Maps self-restarts itself even after logging out of Latitude and closing the app completely

I have attached all the wakelocks to the previous two posts. I didn't attach CPU spy but I did check it every time. Usually it's between 60-80% but most often it's >70% in deep sleep.
Just did a fresh wipe with a app restore using the market. Location services have been disabled. I have uninstalled all gMaps updates and disabled the app. Is this good enough? Should I convert to user and uninstall using TB?
Just wanted to chime in and say I'm seeing a very similar profile to what you posted. And I'm not entirely sure, but I think this started when I flashed this ROM. What I feel like I'm seeing is that active use of the phone seems to be more of a drain than it used to, but I'm not sure how much of that would be placebo (i.e. remembering when I first got the phone around the holidays and there were a lot of relaxed days at home with constant wifi).
But right now I'm seeing 5.5 hours of awake time and 1 hour of screen on time, with 27% remaining. Total time is 42 hours, which seems to round everything out to a decent battery life, but again, 1 hour of use for 70% of the battery seems lower than what I remember. Not sure if a vote for seeing the same behavior is one for this being normal or us both having the problem, but I can try to post screenshots/more detailed info later if it would help.
This is on the above linked rom with stock kernel, 4.0.4 radios.
That's the same ROM I'm using and I agree, 70% usage for 1h screen time seems too much. I've seen people get over 2.5h screen on time on pure 3/4g
I'm going to see if disabling maps and location services help. Will report back.
I would be interested to see any SS you have, might help.
Sent from my Galaxy Nexus using XDA App
This is after a fresh wipe, fresh kernel install, no maps, no g+, no gTalk, no GPS, no location services, just gmail and 1 exchange @ 15 minutes
Any advice as to what's going on would be very helpful. Thanks in advance.
I also have a problem with wake-locks.
Since phone is relatively new ~2weeks its still stock 4.0.2 GSM. After some time my battery life fell and thanks to XDA i think i found the problem Google backup.
I disabled Google backup to see if i get the same awake time tomorrow.
If the problem doesn't go away, is it possible to resolve this problem without factory reset of the phone?
Here are some screenshots I made the other day, taken a bit into a charge but immediately prior the phone was down to <6%. Didn't get a capture of the kernel wakelocks but as you reported, the screen on time falls far below the wake time, and the wakelocks don't seem to come anywhere near to explaining the difference.
I just installed the 6.3.0 google maps, which claims to increase battery performance for location and latitude services. I'll try to make a comparison next time my battery is drained.
I've signed out of latitude before but generally don't redo this upon rebooting the phone. Does it sign in by default on every reboot?
Well after disabling backup thing im still getting 90% wake time from backup service so i will try to do a factory reset over weekend and hope it goes away... Will post resoults in case some 1 else gets this problem.

This looks to me like some sort of Maps issue. Try to uninstall/disable maps and see if it goes away. Looks like it's stuck trying to locate you with maps somehow based on those wakelock names.

Hopefully the factory reset will fix it, that is an odd problem.
It seems to me like my problem was the version of leankernel I was using. I went from 10.0exp2 to 2.01exp2 and it's much much better
Actually, the kernel upgrade did not fix my problem. I did seem to figure out what was happening though.
This entire time I've noticed that my phone would standby and sleep very well on Wi-Fi but when I switched to data it seemed as if I would bleed juice. I discovered that my "Keep Wi-Fi on during sleep" was set to "always" and I believe that was causing my excess wakes.
I've changed it to "Never" and I'm doing some tests. I'll be sure to report back if anyone is watching this thread.

mine is opposite of that, i standby fine on data but terribly on wifi. im guessing that is background syncing. i just have to figure out what is doing it
i have my wifi set to never too for better battery life. It seems counter intuitive, but wifi is better on power than 3g/4g. So preventing the phone from leaving wifi back to cellular is better for battery. All my phones have been like this.
yeah thats what i thought it does but mine drains faster on wifi...i leave it on cause i barely get signal in my room an if i sit on 3g it just takes a long time to do anything
What type of drain do you get over 3g vs wifi?
Yesterday I was playing around on 3g all day and I was seeing an average of 6%/hr. My phone is consistantly awake 20-25% of the time according to betterbatterstats. Screen on will always be far less than half of my awake time. Wifi drains around 1%/hr
I did a wipe of my 4.0.4 install and flashed a fresh kernel download. I'm not logging into exchange because, for some reason, I think that's my problem.
Also, changing to Never didn't really fix my issue.
Hey XDA friends. I got the Verizon HTC One a few weeks ago and battery life started out fantastic. When I put away to go to sleep it only lost 7% all night with GPS on and wifi on and all that and I was astonished. However as time went on I found those results kept getting worse and worse until I was draining 30% in a night. I went and uninstalled battery guru and now I only drain 12% a night. Some nights however I still lose 20% in a night with sleep mode on. How do I check what keeps waking my phone up and draining my battery. I'm afraid this will affect my phone's battery in the long run. I will start disabling GPS at night but I wish I still had that 7% in a night. How do I check what is messing with my phone???

go to settings/power/usage. this will tell you which app is using the most of you battery. also you should never have gps on while youre sleeping. you might also want to turn off auto-sync and then re-enable it after you wake up. you can create a widget to do just that. if you need help with that, just let me know.
Turn data Wi-Fi and gps off lol.... You are asleep

Do you use blinkfeed, that will kill your battery pretty fast. Even if you don't think you are using it, go check and see if it's syncing anything in the settings. I thought mine was turned off, but then I logged into facebook (turned sync off in facebook), later I found that blinkfeed was syncing it anyway w/out my knowledge.

Update: Battery only drained 10% last night with GPS off, Blinkfeed never updates on its own and all social networks are checked off (I don't like my social networks on Blinkfeed) other than that though everything seems to be in check. If anyone else has anyway to improve that 10% let me know (by the way the 10% was drained during 9 hours of constant sleep I went from 77 to 67)

Really, 1% per hour on standby with cellular radios on is pretty acceptable. Depending on signal strength, the radio could be pulling that just to maintain a connection to the tower.
Thanks everyone!
With GPS off, Sleep mode on, and NO BATTERY HELPER APPS (Battery guru was diminishing my battery life) I got a record breaking (for me) 4% loss in battery life during my 8 hour night's sleep, not bad if I do say so myself, after that my battery has been a lot better. I wish Verizon would give us HTC's battery saving software back but let's not ask too much of Verizon or they might give us timely updates.

those battery saving apps are so pointless IMHO, it's just another app and if coded incorrectly will do exactly what it did to you, destroy your battery that is working fine. very happy you can now enjoy your phone the way was designed to be!

Hey..I had the same problem so...first download wakelock detector from play store..after installing jus use your phone like as usual..after 4 to 5 hrs or right before you charge your phone, open the wakelock app and check what's waking up your phone during sleep..for everyone it seems the battery is drained by Google services ..the main culprit being the location services.. so switch off the location services in settings..and also in Google maps, go into setting and then into Google location settings and make sure location reporting and location history are disabled, make sure they are unchecked.. that's it..restart the phone..fully charge it and test it out ..and DON'T use any battery saving apps ..and also uninstall wakelocker app after your battery life is back to normal..I'm an average user and I unplug around 9 in da morning and when I come home around 6, I still have 65% left..I don use facebook .. heard even facebook app is major battery drainer....you jus have to tweak and play with settings till you find your desired battery life expectancy cos everyone uses their phone differently..and we all have different apps so the main thing is to find out what's eating the phone battery most...I'm just pleased with my decision in picking HTC ONE over galaxy S4
similar problem here....google services is killing my battery (relatively). location is part of it, but google hangouts is also going crazy (watchdog alerts me to excessive usage....over 50%, but hangouts was at 100%)
i was spoiled on my g-nex, where i left wifi, bluetooth, and GPS on 24/7 and could easily go 24 hours. now i'm lucky to get 12 (with about 1 hour of screen on time).
I'm hoping things will sort out, device is only about a week old, but google optimized location usage (iirc) such that it isn't supposed to constantly ping and kill battery. we shall see, i guess.
I'm not sure what the problem could be but I'm just gonna say that yesterday I got around 18 hours of battery life with over 5 hours screen on time which I consider awesome battery life.
I'm stock, so it's definitely possible to get good battery life.
10 percent overnight? Thats not that great but not horrible. My dna is running carbon (android 4.3) I use tasker to turn off autosync and data/wifi and put it on silent at whatever set time I make it. My phone drains about 5 percent max overnight, usually a lot less.

you can turn off updates in facebook and its not bad, but yeah if you have autoupdate on, it can kill the battery.
as far as the OP, I don't get why you don't charge you phone while you are sleeping. Seems like the perfect time.
Turning GPS off shouldn't affect your battery life. If you're not using your phone, the phone isn't going to use the GPS for anything. So it shouldn't be using your battery. The culprit is usually an app that is wakelocking your phone. So you need to find which app it is that constantly wakes your phone from deep sleep. Turning off autosync would help a bit if you are really paranoid. The big thing that hurts our battery when the screen is off, is the LTE radio, but most people are connected to WiFi when they sleep so it's not a big deal.
Just an FYI, turning off GPS has been ineffective since 2.2 Froyo. When Gingerbread 2.3 was released like 2+ years ago, it allowed for the GPS to only be used when an app called for it to be used. Otherwise GPS will not do anything unless you pull up an app that calls it to do something.
My battery seems to be draining quite fast. I have removed a lot of bloatware, but I'm not getting the type of performance that others are getting.
It has lost 70% in 5 hours just doing a little browsing, watching a 20minute video and playing a game for half an hour. This was with Wifi on, and mobile data switched off, and background data switched off too.
I've had the device for a week now and I've charged it every day.
Any Ideas on how to improve it?

Could well be your brightness level? Are you using autobrightness or is it on a fixed level (I hope its not fixed at 100%!)
If you use autobrightness try using an app like LUX auto brightness instead.

A shot in the dark:
Do you skype? Skype was draining the battery down in the Nexus 7 2013 even when you were not using it. I disabled it and the battery improved greatly.
Another option:
It sounds to me that there's an app that is draining the battery down a whole lot. I would try to isolate that app (by deleting each one you downloaded one at a time) until you have found it.

I don't have skype, but I like your idea - I've gotten rid of almost all the bloatware stuff. What I think I'll do now is charge it to max. DO a factory reset and not allow Google to start downloading all my apps again.
Funny thing though - when I charged it last night and unplugged it for 3 hours it only dropped a couple of percent. It started dying rapidly after I opened up a few other apps.
What I'll do now is charge do a factory reset, then switch it off, then charge to max before turning it on again. When I first got it, it turned on as soon as I plugged it in. did the same happen for everyone?
What you might want to do is download Greenify on the play store. This will tell you what apps are running in the background and then it will turn them off (hibernate).

Make sure that you leave the battery charging for about 10-15 minutes more after your cradle light turns green. Sometimes the battery isn't fully charged despite the cradle light turning green. 30 minutes on a game shouldn't be using that much battery consumption.
I usually get about 10-12 hours or more on each of my batteries ( video calling, chatting, games and my 4g is turned on 90% of the time

From what I know it lowers the CPU clock speed and decreases brightness. All with the intent of saving battery.
I read that while it DOESN'T limit the CPU, it does lower the brightness and cuts out your data/BT/location/NFC in order to preserve the little bit of battery.
Edit: And syncs.

I don't think it actually does any of that though. I have been using it a lot the past few days half on half off. I still get all MMS and emails right away plus my photos are syncing with google. My brightness doesn't change (auto or not). plus I have BT and WIFI on all the time for smart watch and of course data usage . Maybe the processor, but im not even sure of that. Guess I could do benchmarks with it on and off and see. I just feel like this feature is doing nothing at this time. On my nexus 5 I could really see the processor throttle and brightness him with battery saver.

You can change it to immediately from 15% and i bet you will notice a difference at any battery percentage.
Cpu speed is not affected, just checked this.
Brightness was indeed cut off considerably, haven't checked for other things yet :good:
I figured out why it wasn't working for me. Simply clicking the icon to green in the pull down only enables it when it gets before 15 percent. Didn't force it on now like I thought it was.
Why is there so little discussion on this feature? I found very few threads on this and this was the most active conversation even though it is so old. I found out today I could enable this feature at anytime, not just at 5 or 15%. So I have it enabled at 100% battery and testing today. Upon enabling battery saver mode and restrict idle apps, the screen immediately went dim. I turned it back up slightly. I also noticed apps acting different. Toggling between apps is quicker and the animations are gone. Also, I'm using chrome and it's acting different. It's hard to explain, but if I'm navigating from one website to another, it is feels like it is refreshing every time, it doesnt feel faster. Im not sure what it is doing but someone with more experience will probably be able to pinpoint exactly what is happening. It's not standard chrome behavior.

Not sure with the Chrome part of it. I use a different browser. With FireFox everything feels about the same as before.
I also noticed the animations are removed so there is no fancy domino effect or sliding going on. It's all instant and to be honest it feels heck of a lot quicker this way.
Screen is much more dim and is extremely conservative for the most part.
Clock speed is the same. Although I wonder if there is some sort of under the hood change such as MPDecision switching over to battery saving mode. It personally makes no sense to leave it as is considering in the past it use to cap the clock speed.
So using battery saver today along with restrict apps in background, the former definitely shuts down background data. I noticed Google play store not authenticating paid for apps. I had to go to the play store to launch the app and re-authenticate. That is where I received the warning that background data is off. I have a weather widget and that does not appear to be updating as that uses background data. I have a barometer widget and that does appear to be working as that uses sensor data. All that is required to re-enable background data is to uncheck restrict background apps under the battery saver mode. As of right now, I am at 71% battery and 2 hours 14 minutes screen on time, 3 hrs 53 minutes on the battery. I'm mostly using chrome while screen is on and podkicker and listened to about an hour of audio and a little bit of teamspeak usage with my Bluetooth headset. Brightness is at 37% which is pretty dim in this mode. I'd say it's equal to 15% in regular mode bit good enough to see.
Update, I went all the way to 25% battery remaining yesterday and I had right at 5 hour SOT. In my opinion, this mode is not worth the hassle. Background data is off and that breaks a few things. Screen is pretty dim and I ended up turning it up anyway. I have had similar battery life in the past anyway. I have had 7 hours 20 minutes of SOT before without this mode on and all my widgets working. I'm going to leave this mode off.
It saves battery

yup..i feels like the batrey saving mode is draining more batrey life than not using it..is there a solution for this ?
I was wondering if anybody else had this issue or had any suggestions.
Battery life is normally great on the tablet, except every once and a while it gets stuck awake overnight. There doesn't seem to be a 3rd party app that is holding it awake, as Android system and OS is what's using most of the battery.
As you can see in the screenshot, Doze works fine and barely any better is drained, I used it briefly, came home from work and half the battery had been drained.
Thanks for the help
Not sure if it's normal but mine does the same.

I've seen a 30ish % drain sitting overnight a couple of times over the past 2 weeks. Can't seem to find a rhyme or reason for it.
I can't imagine it being "normal" since, with Wifi set to off while sleeping that the device should drain that much.
It's odd and happens randomly, I'm on the same page as you bluestang.
It happened to me once, at night it wastes a 15% battery.
I changed in wifi advance options to not maintain WiFi always awake, only in charge.

That's the setup I have though - so I get no notifications or anything when it's not on. Yet something is still keeping the device up.
I have *exactly* the same problem with an all new device, and with nothing but a game installed on it. After a reboot, if I let the Pixel C right there for a night, then it only drains ~3/4%.
Then I play the only game I have for 5 minutes, and let the device again for a night => it now wastes a 20% battery!
No idea what's going on... "Android OS" appears first in the list of app, but this does not help me so much to find what is actually happening...
The issue still appears even after a full reset of the system (I'v tried, without success).

Exactly. If I reboot the device and let it sit, doze works fine, the second I open an app, use it and put the tablet down, something hangs and keeps it awake. Always Android OS that is keeping it awake as well...
I have this issue too. Are you guys on xceed Kernel?
Whats really interesting even better battery stats Shows no culprit.
I'm on the stock-just-reset-again last version of the system.

I'm on stock - not even rooted
I'm on stock MM here as well.
Also, not sure if it a coincidence or not, but I changed this and haven't seen overnight battery drops anymore. In Settings>Location I changed the Mode from High accuracy to Battery saving. Since the Pixel C doesn't have GPS device, then why use it.
Like I said, not sure if it a coincidence, but battery life has been great overnight since.

So last night, I rebooted before I went to sleep, but overnight the battery drained from 85% down to 57% in about 8 hours.
I decided to check my location settings as per your post and found it was set to high accuracy, so I changed it to "Battery Saving".
I did nothing else(no reboot) until I checked my battery now about 3 hours later, it has only dropped by a further 2%.
Looking at "Battery Monitor Widget Pro" history statistics, it is clear to see that overnight the battery was draining considerably more.
It takes readings every 10 minutes and was showing between 450 and 275 mA being used every 10 minutes overnight.
Since I changed the location settings, most of the time it is 15mA with occasional jumps up to a max of 297mA.
Although this could not be classed as conclusive proof, it does seem to have had an effect, I will keep monitoring it to see how it goes.
Yep, I change that setting on the 19th or 20th and haven't seen any major drains overnight.
I think I may have found a winner with that little tweak
So far so good for me too. I don't know if it is related to the GPS settings, but no more inconsistent major drains so far.
if location services is on it can drain a good deal
Just to add that I had exactly the same issue on stock 7.1.2, tablet was staying awake and draining. Reduced location precision and now only a 2% drain during an 8 hour sleep which is a massive improvement.
