When I upgrade to ICS, my tablet exhibited all issues everyone was complaining about.
1) Battery drain. - the culprit of this issue is GPS. The GPS was preventing tablet from going into deep sleep. I have disabled GPS but kept Google location service enabled and that fixed the deep sleep issue. Also there were some incomparable software which prevented deep sleep. XDA app was one of them.
2) Random reboots, shutdowns, and lag. - the culprit of these issues is software incompatible. All you have to do is perform full wipe and cold boot using recovery by pressing and holding power and volume down buttons. After reset, all issues are gone.
To troubleshoot use next tools.
1) CPUSpy - it will show of tablet goes into deep sleep.
2)Battery settings in the rom's system setting is helpful to see if the phone sleeps but will not show if it deep sleep.
3) BetterBatteryStates is very useful to see which process keeps tablet awake.

If it were that easy Asus wouldn't be working on a fix to push out to us. They have already confirmed there are issues.
My tablet didn't exhibit any of the reboot issues up until a few days ago. Which means even though your "solution " has seemed to help so far it could end up happening again later on

I have been running for 1d and 20 hours using tablet and still have 60% left. No reboots no lag runs smooth. Also there is an issue with GPS which keeps tablet from going into deep sleep and that is what Asus is working on. If you disable GPS and remove xda app that will solve your battery issue. Also xda might have fixed their app since then. Full wipe will fix other issues.

I understand and believe you. I'm saying that the amount of time you have without any issues is not long enough to be 100% certain all issues are gone.
That is why I stated that's I had NONE of the issues for a couple weeks then out of nowhere they started.
Tho I hope your solution works in the long run and helps others as well

I am just sharing my findings. I think GPS is the biggest contributed. Just disable it and see how the tablet runs.

If a full wipe was the solution, then you will not find so many threads about the reboot or other issues.
it is just pure luck, some did all the steps of full wipe, full reset, go to stock HC then stock ICS, in all ways some keep getting issues and some do not have any.....
and as it has been already mentioned above, the issues have been confirmed by asus and they are already working on a solution.

My experience: I've done a full wipe, installed few apps from scratch (no restore), disabled GPS and installed autoairplane app. Everything seemed ok, two days and one night in deep sleep with 8% of battery drain per day. The following morning the tablet was switched off with 0% of battery
Great that you have resolved the issues for your TF101 and thanks for sharing the steps you took you to get that far.
It's only a limited set of devices though (1) and a limited amount of time.
I still believe most TF101 ICS issues are related to drivers. Just like it was initially with the first Asus HC release. Updates will improve stability.
the culprit of these issues is software incompatible.

I agree, this is just a poor choice of words..and with the title of the thread, you are really just ginning up controversy here now as a thread of this nature has already been closed because of someone insisting that a full wipe solves reboot issues..I would have phrased it more scientifically correct by saying 'the culprit seemed to be software incompatibility', you could even throw in the obligatory 'to me' lol. When you state things with such certainty in a development and electronics forum where terminology and phrasing is very important you are misleading people (noobs and lurkers) who are then going to complain and whine about being misled (and possibly mess up their device in some cases). Safer to state your 'findings' in less certain terms IMO.
And as I already pointed out in another thread, in order to say anything equivocally about a solution to a common problem like random reboots you need to have tested and confirmed the proposed solution on tens and hundreds of units, which very few of us have access to to test with any clarity of results. So anyone *should* take users' proposed solutions with a grain of salt barring they are employed with Asus or Best Buy and could have done such testing. Other users have proposed build.prop fixes for example, only to realize they had reboots and didn't even notice. 1 day is not long n this timeframe- I have one once a week tops..but I still have them..lol
The only problem i had was the apps disappearing from the launcher whenever i exited an app. I thought i solved this by installing a new launcher. But it returned after a few days. I did a full wipe and installed apps from scratch. since then my tablet has been running smooth and fast. no issues. May be it's the apps we install that are causing the problems.

I think it is the graphics acceleration driver. Many games are not working to me, they just exist to launcher and in logcat i can see SIGSERVs because of openGL ( this is from memory, I don't have my tablet here right now).
We must wait until ASUS releases a fix.
I'll come in with another just wait and see like other folks have said. I did my ICS update with a full wipe and then only installed apps I felt comfortable with instead of just doing a full reinstall of everything. For days life seemed grand with everything working just right. Then I got a few reboots and now the constant media converter dying message. So be happy things are working well for you but be prepared for the errors to creep in.

I suffered from random reboots. Whenever my device went to deep sleep it could not come out of it. What I did to remedy this is to root and install set cpu. After installation, i changed my minimum freq to 312mhz and my max at 1ghz. So far, for about a week, i have not suffered any random reboots/freezes. Also, using cpu spy, it does go to deep sleep. I hope this helps.

You are *definitely* wrong on this one. There are numerous documented accounts of people having this problem even on stock, unrooted TF101 tablets that have been wiped both before and after the ICS update was applied, and have nothing or next-to-nothing reinstalled. I'm one such person.
A full wipe most definitely does NOT fix or prevent these problems.

It did for the OP and a vast number of other users. Doesn't work for everyone but it is a viable solution.
I originally suffered from horrible battery life after updating to ICS, but I took a page from the book of the Gnex when it comes to sudden horrible battery life. One of the biggest problems on the GNex with sudden battery drain a lot of the times had to do with Google Maps. I used CPU Spy and Better Battery Stats and sure enough, Google Maps was constantly running in the background, putting the tablet into a wakelock and most likely running the GPS. The tablet wouldn't even last half the day WITH the dock. Went to apps, uninstalled updates and reinstalled the most recent version and since then the battery life has been PHENOMENAL! I've got the tablet with dock and it'll go most of the week, if not all week before the dock starts running low.
Hope this helps others. Can't guarantee it'll fix your problems but it fixed mine.
Speaker Issues after ICS update
Has anyone else had any speaker issues after the ICS update?

My volume is low, also been experienced by others. And it seems like left speaker is lower in volume, which I also read issues with. So yea. I have a couple little quirks. Good thing is I don't really use it for music or movies so not huge deal to me

This has been my fix from the start and have only had one self-inflicted random reboot and (Horndroid here is a nod for you) another reboot after I updated Google+. I reverted back to previous G+ build and all is back that way it was before.
If you'd like to read more about the kernel issue and how I solved it for myself, see here.
Does anyone know what causes msm_hsic_host wake lock?
I've left my phone idle overnight and it has had a lot of this wakelock showing in better battery stats
WiFi was left on if that is relevant
Can't really find any references to this wakelock via our friend Google
Thanks
[EDIT: it appears the wakelock is 'normal' for stock builds and is linked to the radio sending data. some custom kernels can reduce the wakelock]

I saw that thread, though it seems to not really answer the question from what I can tell
Probably won't help but I'm having this problem with my Optimus G as well. More likely a hardware/firmware problem?
hsic = high-speed inter-chip, perhaps some kind of transfer from the SoC to another chip(Perhaps for the modem?).
VDDIO might have something to do with voltage regulation of the bus itself?
Maybe try in airplane mode and see if it solves anything? Otherwise it probably requires an update from Qualcomm if it appears on both Neuxs 4 and Optimus G
I've been having the same problem as well. Battery is draining way too much due to this wakelock when it should be in deep sleep.
Getting the same issue here.
kernel dev needs to shine some light on this

In air plane mode the wakelock dropped from 15% to 6.6% so I'd guess it is related to the modem in some way
little bump for this... seem to be getting same thing.
Around an hours worth of wakelock in a standard day..
I'm having the same issue with mine, 95 minutes of wake lock over a 10 hour period - using in BetterBatteryStats.
Nothing to add but I wanted to bump this up!
I have this issue too. Going to have to do a source code search to find out anything. All my partial wake locks are fine/expected... I'm completely stock, not rooted... no apps I didn't have on previous phones and have never seen this one before.
Could it be a gsm thing? I've always been on CDMA before the nexus 4.

No this is specific to the nexus 4. I have a gsm galaxy nexus and it doesn't have this kernel wake lock.
This wake lock totaled about an hour over a 10 hour period for me. Would definitely like to know the culprit. Overnight on airplane mode, I dropped 1% in 8 hours and the wake lock wasn't there. Definitely radio related.
Qualcomm EHCI Host Controller using HSIC. See line 586 ehci-msm-hsic.c.
May be a coincidence but it is related to USB Host... that doesn't work on our device
Same issue, very annoying. Anyone with a Galaxy Nexus/Nexus 7/Nexus 10, are you experiencing this? Is it tied to WiFi only or just a Qualcomm modem issue? This phone has the latest Qualcomm Modem in it, with a very efficient chip for WiFi if I recall. Maybe someone screwed up because it's not as tried and true?
Getting the same thing anyone can aged some light on it would be great

3 hours of wakelock over a 10 hour period today for me...
http://i.imgur.com/x8S66.png
31.2% kernel wakelocks from this one, from 100% to 70% in 2 hours, screen on like 20 mins. This is getting ridiculous. Might it be root related? I used the toolkit and did the 1 click for all which included root, CWM and busybox.
my phone does not go into deep sleep mode while charging and only stays at 384mhz. and when i unplug and use it for few hours and then charge again, it stays at 1512mhz during charging and becomes noticeably warm. does anyone know why and can help me with this? thanks in advance.

why? my phone used to stay in deep sleep mode while charging until few weeks back. i dont remember exactly what i did that may have caused this problem.

I think it not supposed to be im deep sleep, because the system must manage the charging process. Even when you turn off your phone, and you plug the charger, the phone wakes up to manage the charging.

Yea OP, no big deal in your phone staying at the 384mhz step. However the other problem may be cause for concern. Are you using a custom kernel (or ROM, which may have a customized kernel)? If the phone is stock, are you touching the screen all the while noticing this? How are you monitoring this behavior?
Sorry for so many questions but there are many things that could potentially be going wrong.
Lately I have been having issues with my battery being drained when my WiFi is turned on, wlan_rx_wake is preventing my S4 from going into Deep Sleep.
Any suggestions? are there any compatible kernels that would resolve this issue?
Samsung Galaxy S4 (I337M)
ROM: Stock KitKat 4.4.2 rooted
This wake lock is very difficult to get rid of. You might be interested in the op of this

Hello XDA members,
I have T-mobile Samsaung Galaxy S4 and I was wondering if there is an app that will force the phone to go into deep sleep mode when screen is locked? I feel the battery is draining too fast and the cause of it is that the phone is not going into the deep sleep mode. I appreciate any input from you all.
Give greenify a go from the market.

I use Android Tweaker Pro from the GP Market, but the first version.
It forces the deep sleep. Anyway, you have 3 or 4 selection. Remember to check "disable powers collapse" box.
Don't know if the first version is still available, the second one is not so good for me.
