MSM_HSIC_HOST Kernel Wakelock - One (M7) Q&A, Help & Troubleshooting

Hi,
Anybody else have excessive MSM_HSIC_HOST Kernel Wakelock. My phone doesn't have bad battery life, I think I pretty much optimised it in terms of applications installed, but there is always this one Kernel Wakelock at the top of the list.
This morning, my phone has been unplugged for 1hr 27mins and I already have near 10mins of this wakelock. My phone has had it's screen off since being unplugged. Wifi is on and bluetooth is on. I have received one email via gmail app. My Partial Wakelocks is fine/expected.
I have been in the same location (home). I read this is the modem and thought this wakes to check mobile cell connectivity once in a while and should also be reduced if WiFi is on and connected to internet so all data goes via that and not the modem. I read there was an issue with this wakelock a while ago but never got to the bottom of any solution.
Does the attach look normal and as expected, it would help for those with great battery life to state what they have for this wakelock.
Thanks in advance for your help.

I wouldn't panic over that. Just look. It only existed for like 9minutes. It's pretty much normal.

It was in the N4 and franco managed to get a fix in his kernel so you may need a custom kernel to get it to go lower. It seems to be a qualcomm wakelock. Not 100% sure.

Umm. Well I had this wakelock this morning, unplugged for 30mins, no screen on, no emails, no text, 12 mins of this wakelock, my batt down by 2% already.
Strange thing is yday, I had this wake lock for about 40mins for the whole day yday, so I not sure what's causing it, nothings changed.
Anyway taking mine back tomorrow for an exchange as originally for the Gaps but decided I'll live with that but my 3G issue is causing me concern considering most people getting great reception.

i just checked my BBS: 5m52s (count: 287) of msm_hsic_host wakelock @ 3 hours since unplugged.
Seems like a normal value to me. Since we early adopters always have to do some debugging for the companies, i'd just blame it on the early rom-version and wait for the next 2 or 3 updates from HTC. Or some stable custom rom.

Yep that seems normal but 12mins in 30mins of being unplugged is not right

MSM_HSIC_HOST wakelock is data. If you have a problem with MSM_HSIC_HOST wakelock, something is keeping the phone awake and using a lot of data. Look for other sources to figure out the cause.

I have WiFi on, so everything should go via that. The only thing I can think off that is causing this is the Vodafone Sure Signal at home, I've hardly used my phone and it's lost 6% already in the space of less than 2hrs, with 30mins of this wakelock. However when I'm out away from home this wakelock goes back to normal.
Anybody has Vodafone sure signal and can confirm this?

I have about 3000 plus wakelocks on that daily..I've been searching everywhere but no solution. Really wish this gets fixed the battery is still good but I know it can be better if this gets fixed

Yes, I have this as well, it is actually more than 2.5 hours in my 14 hours usage today, and 2400+ wake locks, I also learned from Google that this is caused by 3g modern looking for signal of 3g connection, but I had 3g off the whole day... But my signal was not very good at home, Maybe that's the reason...?

Sgs4 die users are also complaining and they are already on 4.2.2
Btw I am seeing a lot of other wakelocks which also start with msm_

Found a lil something that explains this wake lock a bit.

Since this wakelock is connected to data service, wouldnt an auto data disabling app fix this till a kernel is cooked to disable it completely?

Hey,
I am also having massive wakelocks from msm_hsic_host and main too, it's gotten worse after the latest update by HTC, I have the unlocked 32GB edition and I am using it abroad at the moment. Any solutions for this, short of having to install a custom kernel and/or ROM?

I've experiencing these same wakelocks since a couple of days. Sometime a reboot fixes it for some time but it's really annoying. So far researching. This has led me nowhere. Did any of you find a fix for this. And are you on stock or custom. ROM?

Phone shutting off when playing pandora

This is an annoying and frustrating issue. I thought it was lte but it did it today on wifi. I thought my backup anker battery was to blame but it does it on the stock battery too. It seems to do it when the battery gets too hot. It will restart eventually without battery pulling but typically it'll be in safe mode and when i restart all my non sense widgets will be removed and my keyboard will be set to default. Anyone have any possible solutions?

What rom are you on? Are you over clocked?
Stock ics unrooted locked bootloader no significant changes
Sent from my HTC PH39100 using XDA
There may be something in the OS that shuts down apps, or the whole phone, when it gets too hot. The phone is going to try to protect itself from overheating. I seem to recall earlier threads from last fall on this subject. What else do you have running that could be turned off? Is the phone inside a case that could be removed to allow for more air exposure?
Last weekend, I was running navigation software (CoPilot), my bluetooth connection for phone calls, and had the screen brightness turned up so I could see the navigation screen in the sunlight. The phone was plugged into the car charger. I got a message telling me that the charger could not keep up with the demand. I turned down the screen brightness and that seemed to solve the problem.
I am using a custom ROM and have not had those problems and I use Pandora everyday for at least an hour. May be something to try.
Sent from my HTC PH39100 using xda premium
It usually does it on lte most of all. I do have a heavy duty otterbox commuter on but its needed for my job. Im a stocker at Lowes. I think i found the cause of my problem today on wifi. I was playing with a siri clone called jeanie from the market. The app is a bit laggy so i dont think its optimized for ice. I noticed earlier my phone was getting warm while playing with it so i disabled from running in the background. I left it on just in case they update it and it gets better
Is there anyway to disable lte and just use hspa+/3G. Not only does my phone run hotter on lte it also has poor battery life. I dont need 36meg download speeds to run pandora

I don't know for sure, but in the play store there's an app 'LTE Switch'

I could not find a specific app called LTE Switch. I found several apps that said they turned LTE on or off. However, they appeared to be for specific phones or carriers.
No app on the market works. Most will take you to a hidden settings page with a drop down menu that you can disable it with...however the menu is locked, and regardless of your choice it'll select GPRS/HSPA+/LTE auto mode. I tried the APN trick but no luck there either, LTE logo was still in the notification bar, and speed tests backed it up...40meg download on both.
I think your phone getting hot may be a red herring.
I have the same problem. I always play pandora over bluetooth, and the phone will arbitrarily shut off just as you've described, but I've checked the past few times and the phone wasn't hot at all (and I've definitely felt it hot while doing other things before).
A few minutes later the phone will reboot in normal mode, but every time this happens the bluetooth antenna will not turn back on until I reboot it again.
Also stock, unrooted, ICS
Yeah same thing here! The past time it did it it also deleted all non HTC widgets.
I was using my anker battery that day and I am realizing it overheats easier than the stock HTC battery and also realizing it will drain like crazy after it overheats. I try to only use that battery at home while my stock one is charging. It'll still do it on the stock battery but not as often. Overall though LTE is the issue here. Funny thing is this phone is actually very energy efficient when its not on LTE. It's a major fail you can't turn it off. It's obviously AT&Ts doing, because its straight locked.

I'm going to leave my otterbox off for 24 hours and try to play Pandora over LTE tommorrow and see if it helps
Sent from my HTC_Flyer_P512_NA using XDA
No otter box no case at all and same thing. Battery cover very warm and phone instantly shuts off. I'm really starting to loose my patience. It sucks because otherwise the phone is excellent but this single issue has me contemplating trying to negotiate a different phone from at&t. It might sound like alot to stream Pandora over the air and Bluetooth but I did this with my captivate for a year with no issues. Having lte isn't the point either because I don't need 36 meg downloads to play 128k bit rate streaming and its supposed to switch to hspa+ when I don't need it. Anyway I'm contemplating a factory reset to see if it helps. I went straight from gingerbread to ics without wiping and didn't have the issue on gb
Sent from my HTC PH39100 using XDA
A thought I just had was maybe its the Pandora app its self causing the issue. A recap of everything:
Didn't happen on gingerbread
Removing case doesn't help
Aftermarket battery or stock battery doesn't matter
Won't shut off when using wired headphones or speaker
Won't shut off with wifi on
Google Music works fine regardless only does this with Pandora
So I'm coming to the conclusion Pandora is not optimized for ics or maybe mine isn't. I installed Pandora on gb so the upgrade may have not translated well for it.

Slacker is a good suggestion, been using slacker for years now. Very data light also, left it running while I slept one night by accident and hit "maybe" 500 megs in eight hours

Pandora is also very easy on data caps but Google music isn't at all. Oddly Google music doesn't overheat the battery though. My guess is Google music is smart enough to see hspa+ and use it while Pandora just uses whatever is available.
Sent from my HTC PH39100 using XDA
Yeah google music wrecks my data. I personally haven't havent used Pandora since updating but I imagine its probably a wake lock issue with the phone overheating. It might be keeping the phone from sleeping properly and over taxing it. (Mind you I'm speaking out of my butt and really don't know if that's the case) I know using rdio/slacker for 8 hours I don't have any heat issues on ics at all. And with the new kernels available the battery life is a lot better
Sent from my HTC PH39100 using XDA
Yeah I'll definitely give slacker a try. I've never been crazy about the Pandora app anyway. Gets the job done but its basic and boring

Worst Battery ever!

I installed more than 100 apps, and loaded 7 pages of homescreen by nova launcher with tons of widgets. It runs much smoother than Gnex with 4.1 and Att One X with 4.0.4 with similar loads. Though there's still slight hiccups at initial swipes. After the widgets' been loaded up, swipe between home screen is buttery smooth. Multitask button is also much more responsive than the other two.
However, my biggest compliant with this phone is the battery. It only ran through 8 hours with less than 2 hour screen on time today! Oddly, Google map used 26% of the battery when I didn't use it at all. Android OS also drained a lot of juice.
Any idea? I think screen should drain 50% of the juice at least.
Try turning off Google Now. I believe that when Maps and Android Services are the major hits to your battery, it's caused by Google Now. I get much better battery with it turned off.
That said, Google Now was one of the major things I wanted to love about Jelly Bean, and to have to turn it off to get decent battery life is ridiculous. Here's to hoping they sort that out eventually.
Those stats are typical for a first charge. I had similar results at first but after a few charges my screen on time jumped up to about 4hrs. I keep Google Now on.

If you don't use maps / navigation - Turn off GPS, set it to find your location by WiFi - triangulation etc.
Your battery will get a massive jump - I noticed it on mine when make was using juice without me using anything like that.

LOL...that's exactly what I thought. I would think after downloading, installing, and configuring all these apps the battery would understandably decrease quickly. In addition, Google Now is "learning" our habits/info. Give the phone a couple weeks after the "honeymoon" period and I'm pretty sure battery life will get better.
I've sort of come to accept the fact that keeping GPS enabled on an Android phone is an unobtainable luxury. I keep it disabled until I'm actually ready to use navigiation, and my battery life doubles as a result. Annoying considering I have GNow, location history, etc disabled and have NO apps set up to poll the GPS - there's no excuse, but whatever, it's a bug.

If I do this, does WiFi stay on all the time or does it just turn on when it needs to find your location? I usually have mine off and only turn it on when I am at home.
I've turned off Google now and disabled Chrome. I've never had problems with maps. Though maps will start to do **** if you have searched for something that requires the maps to be turned on but you actually haven't turned on maps.
Wiped device, rooted, installed the 4.2.1 image direct from Google, fresh.
MUCH better than starting stock at 4.2 and OTA'ing to 4.2.1.
Not sure if serious, but this method worked a miracle for me. I was going to sell it, but not now.

No, he just hasn't had an Optimus G. That device has the worst battery. Nexus 4 is somewhat better.
How many charge cycles has your phone been through? I think you just need to give it some more time to settle in.
Sent from my Nexus 4 using Tapatalk 2
what's the consensus on first charge? mine is arriving Monday and i was thinking i would hop over to the nearest t-mobile store and get
a new sim for straightaway. Should it be booted up and charged to full, left off and charged or maybe run down from whatever charge it comes with?
To be honest I was expecting better battery life with 2100mah and stock Android but it's really not that bad. It's just average. After some tweaking and keeping an eye on running apps in the background I'm pretty happy with the battery.
I am getting good battery life, 16h off charger at 45% 1hr 49min screen on
My battery life's doing just fine. It's draining a lot as I install all my apps, but that's a given. When I use it modestly, it performs like a champ
I'm not trolling. This is like my third charge cycle. The first one with my usual apps all installed. 100 app is what I usually put on my android phone. They've been quite consistent. I use to do 5 homescreen but i decide to stress nexus 4 with 7 pages. In addition, 1h 50min screen on time is not bad considering it only takes 14% of the battery. Which means if screen takes 50% of batterry, I will get more than 5 hours. That should be more than great. So the problem is why Google map is draining the battery when stats page shows it's not really active. You can see from the pictures that even if the screen is not turned on, the slope is still very steep, that's what I hate about. Why cannot android simply standby as power-efficient as iphone? Some posts suggest that i should turn off gps and let wifi to set my location. I'll take this advice and hope for the best.

Xperia Z battery life gone 3h!!! Dont buy it!

Hello everyone!!
I recently bought an Xperia Z, but the problem is that the battery depletes after 3hours of onscreen time?, i went to the store and they too found it strange since it should have around 6 or 7 hours of onscreen time.
They exchanged the phone and gave me a new one, and sadly that phone had the exact same problem( REALLY!!?!?!!), and to top that, it's with screenlight at 25% and every battery heavy options turned off.
So i went to the store to get a refund. In the store another guy had exchanged his Xperia Z 4 times till He got a Z with a battery that worked as intended....
I will never buy a sony product again after this letdown..
And i would definitely not exchange my phone 4 times to hit the "Working-Battery lottery!"
It seems there is some sort of failure in the release of many of the Z's released, i found this guy with same problem

I also have bad battery life, but yet I don't see your point of making this topic at all.
6/7h on screen time really yo? On a 1080p screen... maybe next year. There are plenty of people that reached 5h+
If you want 7h on screen time, get an iPhone LOL! That way we would get rid of you and you would be with the other sheeple.
Topic is useless, can't believe you made an account just to say that.

I don't get it, my battery lasts all day, I charge through the night and take it out at 7 roughly. Then I use it through the day playing games like shadowgun and using social networking sites like Facebook. I also use gmail quite often and I also watch YouTube videos aswell. If I have brightness automatic and battery stamina mode it can last me throughout the day. I haven't charged my phone sine 7 and I still have 13% charge left.

Pretty sure that wouldn't even work. One of the girls I work with just got an iphone 5 and the battery drains like crazy on that thing. She starts at 3am, and by ~8 she is below 15% and has to charge pretty soon after. Then she has to charge when she gets home, and again when she goes to sleep.
Meanwhile, I am one of the heaviest power users I know of, I use my phone for work (flashlight, camera, calendar, calculator, barcode scanner), frequently check facebook, ragecomics reader app, general web browsing and play store browsing, small downloads eg mp3, apps, flashable .zip tweaks from here, frequently check simpsons tapped out, play some dead trigger, watch about 30 -60 mins of movies, receive a few calls and texts, maybe 10-20 mins of music playback. Out of habit I normally pull my phone out every 10-15 minutes and unlock it, flick around absent mindedlu, then lock it again after not actually opening anything :\ not sure how I picked up that habit.
To top all that off, I have my screen brightness set to 100% with adjust to lighting conditions ticked, I have location services and sattelites on, auto sync on, 4g data always on, wifi on but location based activated, NFC on, and finally, also have better battery stats installed and allways doing it's thing as I am also experiencing some rougue wakelocks I am slowly dealing with (still stumped on what is causing audio_out2 and deleted_wake_lock)
Despite all this, my phone comes off charge around 330am, and doesn't charge till 8pmish when it finally runs out of juice. That is one hell of a solid effort as I have done pretty much nothing to help out my battery, and doing everything to make it struggle.
I have only undervolted slightly, and am using doomkernel on KA04 rom. I am not using stamina mode either. Infact, when I was using it on stock rom, I couldn't see any difference between using it and not using it. I can't really see how it would do much IF you had NO wakelocks (or very little). Besides knocking out LED all it really does it disable background processes, if you have your phone set up right you shouldn't really have any anyway:good:.
This phone leaves my previous galaxy S2 in it's dust for battery life under the same usage in anycase (I used to charge that thing about 3 times a day most days).

actually on my iPhone 5 I get more like 9 hours of screen time, sometimes 10. Not saying that your friends account is false, but that sure is hell doesn't seem consistent with any battery rundown test I've ever seen.I can go 2 days without charging it roughly, I'm sure the incoming hate and vitriol for my use of an iPhone as a daily driver is about to pour in from the less intelligent Android users, but this is one of the reasons my iPhone is still my daily driver. That and a consistently good camera.
Cheers~
P.S. I have owned many many many Android flagships and am an experienced power user.
Since when did iPhones ship with battery stats?
Or is there an app for that?
Batteries need a few charging cycles before doing their job properly. It's like having sex for the first time. The first time you might be disappointing but as you do it more often, you supposedly become better at it. Batteries work the same way.

Can't believe you just compared batteries on a phone to sex.
My battery life is acceptable. Getting up to 4hours screen time or a little more from 09 - 22. At this time, I then have about 14% more or less. And this is by alot of whatsapp, messaging, maybe a call or two. This is not using LTE. I find it very battery draining so I stick with 3G. Besided i am on WiFi most of the time.
So as long the phone can do a whole day without charging in most normal days for some people that don't travel alot, I ffind the battery acceptable

[Q] Why is my Android OS always so high? Please help!

Like the title says, why is it so high? I've disabled a bunch of bloat and my phone is rooted but I don't have a ton of apps or much running. Even if I don't use my phone I always see Android OS at the top. I've installed BetterBatteryStats and it's almost always in deep sleep. I know it can't be an app because I have the same few apps from my Note 2 and Android System and Android OS were always all the way at the bottom for me.
I'm not sure what the problem is here. Can anyone help me? Suggestions to try?
Well it your OS. That and the screen will most likely always be the top 2. If it was any lower it would be dead.
Again... my note 2 was never that high using more than screen time. And it isn't all the time. Right now it is only using 9%.... obviously something is wrong then.

Same here. It's has a lot of "stay awake" time too. It shouldn't be this way, but it is a common problem that nobody knows the answer to

You need to get Better Battery stats and see what's using your battery. It's definitely not supposed to be doing that. Two possible solutions without knowing exactly what's going on. Take it to att and get a new one, or do a factory reset and start over.

I would wanna say what is happening with your phone is normal. Screen and OS are always my top 2 and I get about a day and a half of battery life

Exactly. Right now my Android OS is at 28% and I will still get over 20 hours.
Yep, Android OS is higher than my screen usage, but i'm still getting excellent battery life. I'm not concerned!
I'm sorry, this wake lock with a screen on time just over an hour is not normal. Not at all

Yes I now have this problem too.
How long is your battery lasting overall?

My battery is almost dead after an 11 hour work shift with me barely touching my phone. This wake lock lasted almost 5 hours today. It's not right

Cell Standby battery drain fix for AT&T

From the Android Central forums:
Settings. . Mobile networks. . mobile data .. enhanced 4g
Since turning off wifi also stops the drain, I might speculate the bug is actually in the voice processing for wider bandwidth and turning off wifi or enhanced 4g shuts down that section of voice processing, which is keeping the radio alive when it should not.
Thanks for that. I'll try this..
Does enhanced 4g mean LTE? What does turning it off do (besides save battery life supposedly)?

Thats HD Voice (AT&T's version of VoLTE). Turning it off disables the Voice over LTE feature.
Does anyone have proof that this is related to cell standby? I am skeptical that this is the smoking gun for battery drain. I have noticed a substantial drain even compared to my old Moto X (2014) and that is saying a lot since that phone's battery wasn't great. I am trying to see where we can make stride to determine the reasons for it. I have different results in my details. Sometimes android system is the culprit.
I turned off Enhanced 4g last night and cell stand by isn't even on my battery usage list today. It was the top one last night before disabling.
How's the overall life now? I just shut it down myself.
Anyone do this and leave WiFi on and still have good battery. Seems to me that no matter what I do WiFi still causes the battery to drain far faster than it should.

I keep everything on except enhanced 4g and get between 5 and 6 hours of screen on time.

I switched off enhanced LTE but if I leave the wifi on I see a battery drain. With wifi off I get a stable battery. My Edge (AT&T) is on Android 5.0.2.
I remember first T-mobile users mentioning battery was ok until 5.0.1 which was later updated to 5.0.2 and the trouble started.
If we could just figure out how to get rid of Google Play services
Im gonna try this too. I keep wifi on. Time to charge up to 100% and see how quick it goes down
So today I decided to keep wifi on and wow. Battery life not as good. Not having horrible drain, but it is most certainly effecting my battery life. So tomorrow I will go all day without wifi and see how it fairs. But I'm thinking that unless I know I'm gonna be at home a lot where I can easily charge, then wifi will remain off indefinitely. Good thing I have 30gb mobile share data

That's why I gave attribution that I was taking it from elsewhere. you just never know when someone will come along and say 'I wrote that.'
Thanks for finding it and sharing.
Ill give it a try and report back. Does anyone use the "Battery Saving" feature all the time?

I'm about to try leaving it on all day. Anything that it turns off I don't really need so might as well. And let's be honest, who needs all the power this phone has all the time. I'd say 95% of the time I don't need anywhere near the processing that this beast is capable of.
