[Nexus 4 Q&A, Help & Troubleshooting] Matt1104:
msm_hsic_host is also drainng my battery....

i have left my nexus 4 in idle this night starting with 98% of battery and this morning i have 54% and themsm_hsic_host is the highest wakelock with 1h and 56m from BBS...

i'm using Vanilla Rootbox on Matr1x 8.5 cm kernel.

i tried franco kernel and stock kernel but with the same result...

I also tried to change rom like PA, Carbon, Liquidsmooth but it is the same...

Logically i did always clean install using the Kernel Cleaning script when change the kernel or "fastboot -w" from my ubuntu laptop to clean everything.....

help me please..... i'm going crazy!!!!
[Nexus 4 Q&A, Help & Troubleshooting] pedxing:
Let me clear up something. Msm-hsic is normal. Every time there is network activity, you will see this kernel wake lock. That said, in the stock kernel....I think pre 4.2.2.... this lock would be maintained for too long and would cause a slight excess of battery drain. However the lock itself needs to be there... As it will be any any device that uses this Qualcomm network chip.

A large drain while asleep is indicative of one or both of two things.

1. Your cell reception sucks. Even if the device is on WiFi, to receive calls it needs to be in regular contact with a tower. If your reception is crappy then the device struggles to reach the tower. Thus more wake locks.

2. Some app is overly chatty on the network. Find that app and kill it. With fire. For example, turn off the latitude tracking feature in Google maps. That thing is always talking to the network.

If both of the above are true you will get massive drain. Reduce the network activity and you will reduce the wake lock.

Optimum drain on the nexus 4 is 0.4% per hour while on WiFi sleeping with a reasonable cell reception.

Finally I recommend the combination of AOKP ROM with Franco kernel for battery savings. Max frequency can be 1.35 GHz with no real performance degradation.
[Nexus 4 Q&A, Help & Troubleshooting] Matt1104:
Thank you form your reply!!!

I have red about this wakelock and I tried to understand the kernel source code (I work as a programmer) and I understand that this wake lock have to exist for communication purpose....

Now here the signal is good and I don't think it is the problem...

The second think it's strange... I saw that Facebook partial wake lock wake my phone even if I deactivate all about notifications...

Other apps are deactivated and also the gps and location service...

Now I'm using greenify to hibernate Facebook (I don't want those damn notification.... When I'm working I hate them :P ) and I will see if this will help...

It could be that the SMS/MMS service of Facebook to put phrase in the social network is the problem??? It's only a presumption....
[Nexus 4 Q&A, Help & Troubleshooting] pedxing:
Greenify is a good idea...it seems to work well. Another test you can try is before going to bed, put the phone in airplane mode but turn back on WiFi. This will allow the phone and apps to communicate as needed but will turn off the cell radio. Then compare the locks to what you got normally. If it's still high then you have a rogue app. If it's much lower then it's the reception. I typically have good reception in my house...except for my night stand. It's evil for some reason and the signal level fluctuates quite a bit.
[Nexus 4 Q&A, Help & Troubleshooting] pedxing:
Also, I have seen a cache wipe from recovery solve a pesky wake lock on an otherwise well behaving phone.
[Nexus 4 Q&A, Help & Troubleshooting] Matt1104:
Thank you for your reply!!!

I did some days ago the test with airplane mode and wifi on... the wakelock is veeeery small 0.3%...

I was very bored about this wakelock that WAS draining the battery, so i did a drastic cleaning. with the command "fastboot -w" in the bootloader i wiped everything. so i flashed the Vanilla Rootbox Rom nightly (and GAPPS), i did a Kernel Cleaning with the kernel cleaner script and i flashed the Matrix kernel 8.5... after that i flashed the 0.27 baseband version.

I installed all my apps and Greenify.

Now.... IT'S PERFECT!!!!!

With 10h after i unpluged it, the msm_hsic_host is 2.8%!!!

I think that the 0.27 version of the baseband is my solution!!! ( i hope!!! :P )

I hope that someone could find it useful!!

As a matter of fact, I'm on .27 radio as well. It seems better than .33 for USA folks. Rumor is .33 added some international compatibility and weakened things just a bit for US users. I'm on T-Mobile. And of course no LTE on .48 so screw that. :)
[Nexus 4 Q&A, Help & Troubleshooting] Matt1104:
It seems good.... Msm_hsic_host is only 5.4% or 3.8% so it is good!! I had 20%

And that was not good!!

I'm not in the USA but I'm in Italy.... But however it seems to be better!!!

A new result: 2 days since I unplug it and 3 hours of screen on. At the end I had 20% of battery!!!! I love Nexus 4!!! :D

Ive been having this wake lock also. Its ran any where from 40 mins to all most 2 hours. I have sort of thinking it has to do with my weather app. Ive tried accu and intellicast apps when they was used a few time in the day. My wakelock seemed to be higher. I have deleted them and the wakes are back down to around 30 to 40 mins a day. Is this a possabity or just me thing its related?
[Nexus 4 Q&A, Help & Troubleshooting] Matt1104:
Usually it could be related to the data usage of your app... I could suggest you to see the notification settings or the update interval of those apps!!!

If you can't reduce the battery draining you could try to use Greenify that IMHO works very well hibernating the apps you set only when you don't use them!!!

[Nexus 4 Q&A, Help & Troubleshooting] buckweet:
I am having screen wakelock issues and I think it comes down to my Touchdown exchange app causing it. What I mean is that if on cell mode the screen won't turn off, or if it does turn off it takes like 3 minutes to do so. If I uninstall this app the problem goes away and the scree shuts off at 1 minute like it should. I don't have these issues on wifi.

I've tried using better battery stats and wake lock detector app, but none of them show Touchdown causing any issues. So I'm wondering if it's really Touchdown bringing out an issue with the msm_host_wakelock process. I came to Nexus 4 from a GNex and had no issues with Touchdown on that phone.

Ideas/thoughts?? Thanks in advance.
[Nexus 4 Q&A, Help & Troubleshooting] Tozenator:
Hey guys, sorry to pop in, I'd just like a quick opinion.

Compared to some of your pictures here, my wakelocks seem quite tame. Are they fine, as in normal? I have a Galaxy S4 GT-i9505 (and yes I realise this is the Nexus 4 forum, I Googled and ended up here).

Thanks for your time!
[Nexus 4 Q&A, Help & Troubleshooting] mbadge:
This looks normal to me. The wakelock issue in this thread for the nexus 4 shows much higher wake times in comparison. Is there an issue with your battery life or are you happy with it?
[Nexus 4 Q&A, Help & Troubleshooting] Tozenator:
I'm very happy with it, battery life is excellent. Thought I'd ask if there was something odd, just to be sure. A doctor's checkup, if you will.

Thank you for replying!
[Nexus 4 Q&A, Help & Troubleshooting] sumit999:
Can someone tell me if any of the kernels has fixed this wakelock issue alongwith the data drop problem?????
[Nexus 4 Q&A, Help & Troubleshooting] mbadge:
I've been using Faux's kernel. The past couple versions have been sweet for battery life. I've been running the latest beta (15b09_r2) for the past week and I've averaged 24 hrs battery life with a couple hours of screen on time. No data drops and no sacrifices in performance. In fact, his kernel has a turbo boost feature which lets CPU cores overclock up to 1.9 GHz to complete tasks quicker! No experience with any other kernels so I can't tell you anymore than that, but Faux's have been great for me.
[Nexus 4 Q&A, Help & Troubleshooting] robogo1982:
Well, have a look at this (I9505 as well, only rooted with CF-Root).

Horrid. The phone had absolutely NO deep sleep at all. Constantly running at 384 MHz.

Also, sorry for the intrusion, I, like Tozenator, wandered in here while googling for this issue.

Nexus 4 Battery Drain | with wi-fi, data off

This Nexus 4 is a real crappo. I had my Nexus 4 fully charged last night before retiring for the evening. 6 hrs later, Wi-Fi and data both OFF, it is at 4% battery life. What a crap phone. My SG3 had no issues at all in sleep mode. This is not worth the money spent on the phone.

Ah.

I didn't seam to have problem with wakelocks before. And installing touchdown is one of the changes I made. Along with messing up with the location settings. And I did have issue on the sola with touchdown sucking the battery dry as well.Touchdown might be culprit there again.

A bit of googlling

In my case, data is off when i don't need it. Seam that cause touchdown to look for connection again and again, despite being on manual sync only mode...

I recently had to RMA my Nexus 4 and when the new one came in I installed the exact same ROM (AOKP) and kernel (Matr1x 8.5) and now all of a sudden I'm getting this wakelock. It was never an issue on the original phone but now I can't seem to get it to stop. I've tried a few different kernels and ROMs, no difference. Makes no sense, as all the apps on the new phone were restored from the old one in Titanium Backup.

[Nexus 4 Q&A, Help & Troubleshooting] hallucynogenyc:
Seems like it wasn't the problem as 3Shirts suggested. I just woke up, unplugged it one hour ago and 28 minutes of this wakelock already. I can't imagine how good the battery life would be if the phone could deep sleep properly...

Add me to the list. I hope this is not a hardware problem and that a software fix or a custom ROM/kernel shall fix it. Tried everything, factory reset, stock image, nothing seems to work except shutting all wireless data (wifi & 3G) which is unpractical.

I'd like to chime in real quick too - I'm currently on an HTC Droid DNA experiencing the same issue. We're on Android 4.1.1.

I found this thread by googling "msm_hsic_host," as that is the main culprit in my wakelocks as shown by better battery stats. People seem to be reporting great battery life with my phone, and I'm not getting it at all because of this. :o

Based on the fact that we are seeing this issue happen on the N4, Droid DNA, and Optimus G, I am thinking that this has some thing to so with with the S4 pro since that is the only common denominator. BTW, this issue is happening to me as well on my N4.
[Nexus 4 Q&A, Help & Troubleshooting] Rslegion:
I get the same wake lock on my One S, so it's not specific to the S4 Pro.

[Nexus 4 Q&A, Help & Troubleshooting] CMNein:
Ran a test last night, unfortunately in my sleepy stupor when I woke up this morning I didn't observe the time in state stats...derp. If I had to guess based on this wakelock, and others I'd guess deep sleep was ~95%. On my GN on 4.2 deep sleep % would be 97, sometimes 98% all things being equal. Both phones running the stock images, rooted, BB.

Anyways over 14 hours I got 18 minutes of the wakelock

. This was with sync off, wifi/data on, connected to wifi. I've reset CPUSpy and have created a new custom reference for BBS so I'll see what type of numbers I see now with sync on, 2 accts on push, one polling every 2 hours, same location, etc...

The presence of this wakelock doesn't appear to lead to any abnormal drain in my case, it's still an essentially flat line battery profile when no one is touching the phone.
[Nexus 4 Q&A, Help & Troubleshooting] sona911:
Ok figured out something that might be the problem, hold your phone against your ear in a quiet ambient, you might here the earphone speaker hissing or buzzing very qietly, this means the earphone is on and consuming power for some reason, and I am afraid this is a hardware issue that cannot be fixed by a firmware update and this might be whats eating the battery. Google if there is one thing you need to learn from Apple, you have to abandon those crappy manufacturers please. Quality is everything. :(

Mine was pretty consistent at 10% of my total time is taken by this wake lock. Just for fun I went ahead and renamed cellbroadcastreceiver.apk to .bak and rebooted because this app can't be disabled via the apps setting screen. So we'll see how that goes today.

I have the paid version of bbs as well. Great tool.

By the way this wake lock seems a lot like various wlan locks on other platforms that are also triggered by incoming data packets. I had one on my galaxy nexus that was actually caused by a chatty network service on my lan. USB print server of all things was spamming the network and making it so my phone could never sleep.

I used the sniffer app shark and shark reader to diagnose this. Right now I do have a dlna device that's a little chatty and when I turned it off the hsic wakelock decreased a bit.
