I have no idea how to get to the bottom of this. Everything I normally try simply doesn't work when it comes to fixing this problem. In Better Battery Stats, it's clear that something is causing the modem to stay awake, because msm_hsic_host is a direct reference to external modem. I will literally have 10-20 minutes max of partial wakelock from sync and then I will have over two hours of msm_hsic_host wakelocks. Avast and Better Battery Stats all do not show any application taking up significant data in the background.
This is making the difference between 4-5 hours of screen on time and 6-7 hours of screen on time. Is there some sort of method to figuring out what is destroying my battery life?
Don't know if this information will help, I have used wakelock detector from play, a free app to show various wake locks .
Also tried Qualcomm battery guru, again free from play , it's a beta app specifically for phone with Snapdragon soc. When first enabled it monitors your phone usage for over 24 hours before enabling various power saving options, that can be customized by the user.

hmm.. interesting to see this as i thought this was a 4.2 issue. See this thread below. The wakelock is related to a driver issue from qualcom who makes the snapdragon s4 pro and 600. They released a patch that has been merged into various custom kernels but the issue remains in the AOSP stock kernel to this day. This is a main reason why i dont mind being on 4.1.2 instead of 4.2.2 until google or a dev for the HTC one fixes it, your battery life will suffer

I ran a wireshark to figure out what was causing it.
One of my issues was Hotmail sync. Setting it to Push apparently means that it will constantly send packets back and forth. Stupid, but whatever.

Hey,
can you explain how you ran a wireshark? I have this wakelock and can't figure out how to stop it and I dont use hotmail sync
Same problem here.... Lot of wake locks and can't find out what causes it.
24% lost in 9 hours sleep mode.
I have the same problem. Because of this Wakelock my HTC One won't go back to DeepSleep.
Is there no app/tool to observe which ap causes this wakelock?
did anyone find a solution? which network are you on (i'm on vodafone nl)
Facebook messenger!
I had this issue as well.. the wakelock was doing its thing like 50% of the time.. removed facebook messenger => the values are back to normal.
Please post if you can see the same..

Here's a really good explanation on what this wakelock is and how it's being produced.

It's apparently much better than the n4 which had nearly the same wake lock as off-charger time. The snapdragon 600 with HTC has much improved the wake lock times.
i woke up today to see this happen for the firs time to my phone.
newest changes to mine: installed ARHD 9 (but it was fine the day or two since, only last night it was unplugged from the wall, instead of the usb port)

Hey I have just bought HTC One 2 days ago. Compared to my old Sensation XE battery life completly sucks. I usually use phone without battery saver, on auto brightness and with Wi-Fi/3g turned on only on demand. Today 8 hours after unplugging phone from the charger I only have 26%. Screen was turned on for 2 hours and 45 minutes only and Wi-Fi worked for 3 hours and 46 mins. I might also say that I did not charge my One before usage to 100% as HTC advised. Was that very crucial? Do you think that phone might be broken or I should just give him time to settle baterry better.
That's sounds like what I get. I turn off mobile data when using WiFi and vice versa. I always use power saver unless I'm 3D gaming. Which is only on the weekends.
I've had mine for 3 months now.
I've seen people get 7:00 screen time on stock unrooted.
I think my battery's broken too. I can barely reach 3 hours of screen time. With 2 hours I get like 11 maybe 12 hours of on time. Something's wrong with our phones...
Does anyone have any suggestions?

Your battery stats seem on par with me and the OP. Seems that only a select few phones get decent battery life.
My kernel (android os) has been in the 25-35% range,it has never been that high before.
battery life lousy
I get pretty horrible drain too. I charged it to nearly full around 7:30 last night. I took about 2 minutes of video, sent one text, and checked my email 3 times. After that I went to sleep and the phone sat idle. At 6:30 this morning, I'm down to 9%.

Wow, that's real bad.. When my phone is off during night maybe 7% is gone. Then again I'm rooted and use greenify aswell as battery doctor if that has any affect.
On screen time seems like my battery drains pretty fast too though. After 2 hours of music and surfing and watching videos I guess atleast 40% would be gone.
My battery life became horrible, too. My phones loses 4% per unused hour. No App seems to be responsible for that drain. Flightmode or powersaving mode ain't making a difference. I hope we'll find a solution for our drain.

@Racingmatt your power management services is on for quite a bit. do you have alarms.? i would bet that you either that maps location enabled or something of the sort. cause you also have NLPcollector on for around 40 minutes which is a bit much. also i would turn off GPS if your not actively using it.
@Rachorid how are you setting up your wifi? is it set to always be on? or set to turn off when screen off? you have alot of wifi wake. might be due to that. i know when i'm at home my wifi actively pings all devices connected which will force wake up my phone. yea its a bit annoying but i live with it. otherwise i just keep my phone plugged in.
if you both can get some SS of alarms i can give you a better idea. and when you SS the alarms make sure to click on the ones with the most wake lock so i can see the secondary screen that shows what the actual wakelock command is happening.

Here are the latest stats. As you can see many Google wakes.. removing Maps/Now/GMail/turning of Location (a few days ago) had no impact on my drain. The 2nd app on Partial Wakelocks was used actively.
I also disabled Wifi for about 2 hours.. no impact, too. Flightmode also had no impact (a few days ago).

I had awesome battery life a month ago with Wifi always on, auto. brightness and every app on hourly sync. (I have my phone since 7th of march) Sometimes I didn't lost a percent over night (8 hours) and I just don't know what it could be because I didn't install another app and no app seems to be responsible for that stanby drain. My on-screen battery life is still good. It also doesn't matter which ROM or kernel I'm using.
Here is my latest stats after 12 hours with 5 minutes of GPS use (turned off when not using)and network location on all the time with 3g/4g on all the time(turns off after a period of inactivity) . I can't give you a alarm stat because I'm not rooted.
Lithium-Ion batteries used in today's smartphones need atleast 10 cycles to show optimum power
so hold on until 2 weeks then you will get the full performance
i get 2 days of battery on my HTC One (since i dont have internet on my Simcard)
its 2G connection and auto Brightness and switched bloatwares off
i use Android Revolution HD 12.2

Yeah seems to be a common android problem, some apps have runaway processes, others prevent deep sleep and I have also seen kernels lock CPUs. Shame Google can't put some effort into fixing it.
It's not an Android or a Google problem, it's the fault of the developer of the App which is causing this...
Since 4.3 I lose 0 % over night and I can use the table 1 hour every day for reading magazines, e-mail and angry birds for at least 5 days! Just great

Google / Android should not let an app prevent deep sleep imo. Or runaway with resources. But yes you are right some responsibility has to be with the app developer for sloppy programming as well.

You can wathc under "settings" -> "energy management" -> "energy table" which app it is and you can prevent it to wake the device up and to keep the device alive.
A few weeks ago I had a similar but stronger akku draining problem with the google apps but its gone (a pitty that I can´t say what it was: me doing this things in the energy management or google updating its app).
My google play-services still wake the device 869 times in 3 days.
New results. Very strange. No power consuming app seems to be running, but I still got -3%/hour.
Battery statistics shows that 80% most power is consumed by the screen. But it the tablet was in sleep all the time, so the screen was off...

Check in Settings on "Energieverbrauchstabelle" (something like "engery consumption table") from Asus, there you can see the power consumption of the apps without Display. If you click on a specific app you can disable it to keep awake or wake tablet from deep sleep...
If that not helps you you should reset everything and go back to stock. Then you can check without installed additional apps if your "bleeding" still is there. Then install one app after another and wait between every single one to check which is the "bad app"...
So, in fact it was a hardware issue. I took another unit and it works perfectly. For now...
Anyway, thanks for your help, guys

I put together a list of things that helped me get 7 hours SoT on a charge (Wifi). Edit: 6.75hrs SoT. Edit2: 7.75hrs SoT No root access or modifications needed for these.
This is my first Android device and I wanted to share some of the things I've learned mostly reading these forums. It also annoys me to read users complain about their battery life but are unwilling to do anything about it. I hope this will help people to realize the full potential of their phone.
Llama, Tasker, etc: Automate everything you can to save battery. It can be more efficient to run a line of code then to tap the screen.
Force stop all the programs you don't really need running in the background in Settings > Apps > Running. Basically act like your own Greenify. Or use Greenify.
Wakelocks: Track the "Awake Time" of suspicious applications and services and either reboot or force stop them if necessary.
Disable Google applications you don't need. Myself I disabled Chrome, Gmail and News & Weather.
Disable: touch and typing vibration. I have type sounds On and touch sounds Off because those really add up on speaker.
Disable: NFC, Bluetooth, Wireless printing etc. Automate to run only when needed for no lost functionality.
Wifi: Automate to turn on only for Wifi zones of your choice. No lost functionality. Wifi always scanning: Off.
Notifications: Apps and games can send you unnecessary notifications. Disable them. Enable only what you need.
Hotword detection: off. This specifically drains SoT and saves only a single screen tap.
Widgets: These drain battery without ever showing up individually on the stats page. Silent killers.
Lux: Another silent killer even when set "On Wake only" and "Slow". Just by disabling Lux lite and a once-daily updated Feedly widget I noticed significant SoT gains. Using Llama to automate brightness is more efficient.
Speaker vs Headphones: The speaker seems to use more battery.
Two apps that can help you monitor your battery and phone with no root requirement:
Play Store Link.
Current Widget - Set to update manually on your home screen for minimal power draw. Check your charge and discharge rates along with battery temperature.
Play Store Link.
S Tools+ - This just popped up in the XDA apps section the other day. Detailed information on CPU states, Deep Sleep time and ALL your sensors, nicely graphed and very polished including transparent nav bar. Other than real time graphing of sensors this shouldn't be much of a drain.
Speaker vs headphones....what?? Care to explain how? I'm saying the difference is negligible.

Yeah, you really don't need to do all that to save battery. Just don't turn on data until you need it and you'll get a week of standby on a single charge with this phone, and a full day of usage (or more depending on how much you use it).

Not sure if serious or not. That functionality is enabled on the phone by default and you'll see many people struggling to get over 3 hours SoT like that.
There are even reviews which seem to think topping 3 hours SoT is some kind of miracle. Most will answer that by saying: "you need root and flash x ROM with y kernel".

Gotta agree. The vast majority of users charge overnight and with my own setup - currently on stock rom and stock kernel (though I'm currently bouncing between that and Franco to see which I prefer) with pretty much everything always on (NFC, WiFi, data, location access, though I disable notifications from the likes of Facebook, Twitter, etc. just because I'm not that invested in social networks that I'd want constant updates) I can get 3+ hours SOT - which I'd assume is more than enough for most people. Greenify is to thank for most of my battery savings.
But don't get me wrong - for those who do need more SOT than that, the OP is fantastic advice, and I'll be coming back to this thread when I'm on holiday etc. and won't be able to charge every night.
great tips
kuddos to the OP

don't mind the haters. they're just mad that they only get 3 hours of screen on time and 10% battery drain per hour when deep sleeping
they would rather complain than take control of their device and if you dont use your own phone exactly like they use their phone, then they call foul and tell you that your results don't matter. they say the same thing to people that use their device like an ipod touch(by putting it in airplane mode).

I think it's just really hard to get good auto brightness on this phone right now due to the sensor. Using Lux Lite didn't help me very much since I was bouncing between very low and extremely high brightness but I imagine the full version could be more useful.
Llama is an extremely light weight application and uses only 6MB of RAM, the lowest of any service I've seen. I think it could add to Android System drain but using Cell Tower locations and properly set up conditions I don't think it will by much.
Thanks for the supportive comments. I really just want to help and have no hidden agenda here. We've known for months now that the N5 can get 8.9 hours SoT web browsing on WiFi and 6.9 hours web browsing on LTE. Of course Anandtech used perfect, non-root conditions with airplane mode On, Gnow off and zero apps or widgets; something that even I am unwilling to put up with. We can still strive to get as close to those numbers as possible.

Generally speaking SOT depends on what you are doing.
I've been down this road and can get SOT times on any phone pushing 5 hours.
To say no loss of functionality is wrong. You state to kill half the apps that I use so that is a LOF to me.
The secret, well not really, is the brightness and network reception.
Turning down the brightness and getting max signal/bandwidth will affect the battery more than turning off apps. Remember the rule of thumb the longer the phone has to stay on for a wakelock the more the battery drains and that is SOT and sleep. What I mean is you'll drain your battery faster connected to a dialup internet connection than fiber at 1gig.... It's all about bandwidth and high signal strength and screen brightness.
Not hating just saying that no one person can say this will give you X number of hours of SOT when everyone's signal/bandwidth environment is different.
So the poor battery life on my Note 4 might have more to do with screen brightness than I would have expected. Unfortunately, most people posting their SOT's aren't doing it in a very scientific way, so it's hard to know what we should expect from these devices.
Here are my battery test results using PCMark for Android https://play.google.com/store/apps/details?id=com.futuremark.pcmark.android.benchmark
In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

thanks for tests im using my exynos version on auto brightness and generally get 6 hours SOT. i saw on alot of people s stats and people who has problems generally has google play services on their battery usage list and it definetly shouldnt be at there... its probably about location reports to google every1 should disable it from location settings it doesnt break anything.

Yes, location can be an issue, but I think that impacts standby time more than SOT. Currently I've done the following to help with location-related issues:
- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

last night with 10 hours sleep time. with wifi connected sync was activated for 3 mails. i just lost 2% and i didnt do anything special like you did. no greenify no root nothing i couldnt even install wakelock detector cuz its broken on kitkat without root.
. i just disabled some useless stuff like samsung store etc.. everything else is working. and on my car i generally listen music over bluetooth
Lux could help

Before I started tweaking, I was getting around 6%-9% drain PER HOUR! Disabling stuff without root only got me so far, then the xposed tweaks and Titanium Backup had to be used.

like i said i dont know whats wrong for some people its probably something you installed(skype maybe) or mostly about location reporting. even last night i left my phone at 90% when i get it this morning after like 10 hours it was on 88% like i said earlier wifi was connected no power saving etc just normal idle time nothing special.

I was testing without any apps installed (just whatever I used to record battery consumption) and it was crazy high. Then I started adding accounts and apps, tweaking and I got my standby time to be much lower, but SOT leaves much to be desired. I'm going to try using the manual brightness and see if there are any differences - I often find auto brightness to be too bright or too dim! No "sweet spot" found! LOL
Greeny can also help but may need root
I'd suggest changing the settings for your Battery Monitor Widget app. AFAICS it polls every 10 minutes so a wakelock occurs every ten minutes to save the data. Use something like an hour and see what happens. Also would highly recommend BetterBatteryStats, a free version is available here for members.

I'll try that, although that might only improve wakelocks, not screen on time.
BBS never worked right for me. Always complaining that it couldn't retrieve the stats or falling back on something else.

Wait, with the screen off? Then you have something horribly wrong with your device. Mine did a few % over a night. With nothing done to the phone to conserve battery at all. Snapdragon, though. With the update.
I loose only 2% for 7h of standby last night.
We are seeing a trend I think, I noticed that it's mainly us 910U users or exnyos users complaining about battery life. So it must be something in the 910U rom?
I've got a 910F and I get 6 hours screen on time maximum :/

Doesn't happen now that I've rooted and applied my standard tweaks, but I tried a factory reset to see if I could correct the high standby drain and was not successful without these tweaks.

I have 910f and i got same issues with my batt.
i've tried clean system, root, custom rom. Battery is always draining higher than some people.
As i said in other thread: some people have an issue, some have great battery life. And nobody knows why
Maybe it's the guys who keep it stock and don't root, custom rom and "tweak" that get the good battery life.
Delete it pls.

I'm on stock, but without tweaks I can't even go the day on standby. [emoji31]
