Hi!
I've recently discovered quite large battery drainage. I've installed BetterBatteryStats and the problem is that the process named "msm hsic host" is working all the time. I've red on this Forum that's a common problem with the Nexus phones, but I couldn't find any solution for Samsung S 4. Is there any?
I would be grateful for any kind of help.
Best regards
MSM hsic is for communication to modem (network chip, not wifi)

HSIC is technology for inter processor comminication. Our phone has two main chipsets AP (here snapdragon, thus the name MSM ) and modem chipset (again by qualcomm). They both are connected via hsic, which is based on our very own USB . The protocol stack is also the same of the standard USB 2.0 !
Everytime the CP (modem ) tries to communicate with AP , say for network notification or small time data sync, you will see a wakelock being hold by the hsic driver in android kernel. Its being hold so long the data transfer is there and wakelock is released after some safe period of no activity.
I admit its one of the most holded wake lock often interrupts and wakes up the system, but that whats it does to us.. it keeps us connected.
If you wanna debug something whithout interruption from msm hsic , do a airplane mode on. This will shut the no. of suspend wake up by over 90%.
Hit thanks if i am able to explain in due time

Upgraded from Nav3 to 5 which is working great except that the PDA will not power off automatically with Nav5 running. Also even if I manually switch the PDA off the battery consumption is very high (runs flat overnight). I'm not using bluetooth or WLAN and they are definately off. I don't have any other app's running.
Anyone else have this problem or suggest a workaround?
If I Stop the Nav5 application then power functions as normal but being forgettful it's hard to remember to do this every time!
Of course Tomtom support have been as useless as ever!!
It maybe dumb to suggest, but....
...do you 'Exit Application' when you've finished using TTN5?
If you don't, it will keep polling the Serial Port for your GPS reciever, and thus the handset won't fully 'stand-by' as serial activity will drain power.
I use TTN5, and as long as I exit, I have still got around 2 days out of a battery, with 'careful' usage.
No offence intended at all in this post - just perhaps highlighting the obvious!
R.
You are correct that exiting (ie Stopping) the application resolves the battery drain but I was using TTN3 previously with a serial receiver and that happily shut down when the PDA was off and did not need stopping.
Also with TTN5 running it stops the PDA switching off automatically, I have to switch off with the power switch.
I have an XDA II and M2000. i have the battery drain problem on both. i exit the app like i am supposed to, but when i start the device in the morning it has completely run flat! in the task manager there is nothing running when i put the device in standby...
any further thoughts?
i am using tomtom v5.21 and the latest roms.
Maybe do a scriptlike "shotdown all" before it goes into it's nightsleep
But i don't see a problem in shutting down TTN5 if you don't use it...
I don't even see a problem in switching off the Radio if i'm not listening etc. No pun intended, but if a programm keeps running it's pretty likely it drains the battery. You're just lucky if it doen't...
Do you know if it's possible avoid turn-off wireless in stand-by???
I'd like to use VoIP with my Artemis (with hand-free and wireless connection), but it's impossible becouse after 1 minute (my pda is set to turn-off after 1 minute) the phone goes in stand-by mode and plugs off the wireless antenna.
Can I set "Always on" to wireless connection???
as yet i failed to accomplish this. all i can do so far is turn off the monitor to save a bit power. not the same as standby mode at all though.
I've got this tweak from somewhere, I'm not sure (maybe wiki page):
"AUTO DISCONNECT WHEN GPRS IDLE
you can edit the registry key ...
HKey_Local_Machine/Comm/ConnMgr/Planner/Settings/CacheTime
Change from 600 to 60
it will disconnect after connection is idle for 60 seconds ...
There's also another key needed to be set. Otherwise, my PDA still has always on 3G data connection.
HKey_Local_Machine/Comm/ConnMgr/Planner/Settings/SuspendResume
Change from ~GPRS! - Always on
to GPRS_bye_if_device_off - switch off after timeout"
It may help if you make the changes THE OTHER WAY ROUND. For you the desired value in 'HKey_Local_Machine/Comm/ConnMgr/Planner/Settings/SuspendResume' is '~GPRS!' And the cache time value should be set to '0' (as infinite), if it doesn't work, set to a high value (i.e. 3600 - it means 1 hour).
I'm not sure it helps but it's worth to give it a try...
i guess he was talking about WLAN connection, not gprs or 3G. however, i might be wrong.

You are right, sorry. I've just misunderstood the problem, paying not enough attention to the first post...
So the only way is disable auto sandby and swith-off screen?
I thought a way to solve this situation could be keeping active OS during VoIP connection, just to avoid standby...
Its not enabled for a very good reason, it consumes so much power your device would last just a few hours before running out of power.

that is true. however, they could still give us the option
i think the real "problem" is that WLAN needs the OS running to work. the GSM unit is working differently.
Using S2U is a solution for me

It seems to be what I want, an application that avoid standby mode but preserve battery (setting lcd off, various device option off...)
I'll try it!
Thanks
Skype
I am not sure if this is still relevant, but in skype i think to have seen an option that says: "disable stand by mode when connected to Wlan" or something like that...
however of course the "batteryproblem" will still be there...
Please post your experiences with S2U2 once made, thanks!
Don't mean to "thread jack" but how can I tell the difference between the screen just being off and the phone being in standby mode?
I'm asking because I'm having a problem with my phone when I turn on Flight mode. Usually I turn on flight mode at night or in a meeting but I'm finding that the battery is still draining (rather quickly too) when I'm in flight mode and the device is off all night. If I'm at 40% batt level at 11:00pm and put the phone in Flight mode, by the morning about 6:30am, the battery is down to like 5%! And there are no programs running at all, screen is off, device is untouched all night. So when I saw this thread, I started to wonder if the phone was in really in standby or if the screen was just off.
Is S2U2 the option to keep the WLAN enabled when in standby mode?
I know i can disable going in to standby but would be nice if it can be done without this.
The power drain is most peoples concern but if i'm at work i have it plugged into the power anyway but would like to use one of the WLAN's here that isn't being monitored
Hello everybody,
I own a samsung sgh-i780 with standard rom (win mobile 6.0).
Its a nice phone, but there is one problem which strucks my nerves.
When the battery is low, I am not any more the one who tells my phone what to do, but my phone tells me what i am still allowed to do.
So when my battery is low (below 10%), the following functions are denied by wm6:
- using the camera
- using the phone function (calling someone, etc.)
Using WiFi is still possible. (is it a phone or an internet station? :confused)
I tink I should be allowed to decide for what I want to use my last percentage of the battery.
Is there any trick (e.g. in the registry) where can decide on which battery level the phone and camera will shutdown? I would set it to 0 ;-)
Thanks in advance,
butch
Oh lol thought you wanted to disable it when reading the title.... i would love to turn the 3g off on low battery, probably saves some power
that's not my point.
following situation:
battery is below 10 percent. i start a call. suddenly my mobile stopped the call and disabled the phone function. after i enabled the phone function again it was disabled by the phone some seconds later. but still after minutes i was allowed to use wifi to browse the net, but i was not able to call anyone because my mobile says m battery is to low. what if i need to do an emergency call? should i write an email?
hope my peoblem is clear now.
i wanna be able to set calls until the battery is empty and the phone is shutting down.
regards
butch
hi again,
does noone have any idea?
Does the problem still exists with a 6.1 rom for the sgh-i780?
greetings, butch
MC75A
Hey,
I think i got the same problem.
I am support a project that works with the Motorola (Symbol) MC75A.
Sometimes the PDA disable the phone functions and the end user doesnt have the option to reactivate it.
No im really searching a long time were this behavior came from. And finally lands here now i have to check it.
But is there generally an option to set the Phone function permanently ON and remove the option to disable it?
Device: MC75A (Motorola)
Operating system: WM 6.5
Thanks in front,
Matt
Crashes when I get text message or try and turn off wifi is it my battery in my dash? or firmware bugs?

you should use BandSwitch so batteries are not wasteful...
Dual line support with two pin codes.
If the password(s) is/are incorrect the device will sound and vibrate and show Pin Page.
Pin enable user: remember to enter pin(s) again after reinstall.
Looking in my magic glass bowl and speculating about what you did not tell to judge your situation, I guess:
- messed up installation of SW on the system -> do a hard reset
- weird custom ROM settings -> use another ROM or shipped ROM
- check how long your battery lasts with standard load (see my signature)
Saving battery power is always a good idea, but unless you are in very bad radio coverage, switching off the mobile or radio is not helping much for battery life. Your operator sets the interval for the mobile to reconfirm its location even if not moving, so for some operators the load may be high on battery during the night, for others neglect-able.
Automatic disconnect for WIFI is already part of the standard settings, no need for a dedicated tool imho.
Been getting this at the top of my wake locks and have no idea what it's related to. Any ideas? Thanks.

its 3/4g data. usewifi more
Its for the IPC driver (HSIC) that connect your CPU with the network Modem

Excellent, thanks. However this appears to also be the case for Samsung galaxy s4 which has similar hardware. As android has the binder for IPC on kernel level, id suspect a third party Verizon app driving this additional background process holding the phone awake. Knox or updater perhaps?
