Hey xda. I downgraded to 2.3.6 to upgrade ota ics not thinking about it getting rid of cwm. My phones unlocked but I don't have root and have no access to a computer. Is there a way to root via the phone itself? Thanks for any help!

I don't think so. I tried searching around for you but I couldn't find anything.

Deep Idle does NOT cause your phone to use less power when screen is off. It already goes into Deep Sleep for that. Deep Idle ONLY gives battery savings when using your phone with screen off, such as when playing music or using GPS.
Ya I couldn't find anything through search either, but I thought I'd ask to see. Thanks for looking!

Last night my Tab had 75% battery. This morning it was dead and wouldn't turn on, even after 4 hours on charge. Now when I go to download mode, there is a picture of a phone with a yield sign and then a computer symbol. I can't do anything with it. The only thing I've done is root it over a year ago. It has the stick GB rom. Any ideas on how to fix this? Thanks!

Phone-!-pc mode is download mode. Just flash stock rom in Odin/heimdall.

And how on earth does "help!" describe your topic for people browsing the forum?
Titles are supposed to be descriptive not just silly one word titles like "help!", Please use some common sense.

With every electronic gadget using Lithium-ion batteries nowadays, it doesn't really matter how/when you charge it.
Some would argue to make sure to allow a full discharge from a full charge from a battery calibration point of view, so the battery meter is more accurate. It wouldn't affect the health of the battery itself either way.
Things like memory effect doesn't apply to lithium-ion. How often you charge it and how much you charge it (full or partial charge etc.) doesn't affect it much either. The only 2 things that can potential kill a lithium-ion is high temperature and letting it discharge far too low to the point that it cannot be charged up again. Note that all electronic devices will power off way before it even reaches this threshold.

Read this in a different thread when i was unboxing my nexus 7, i let mine sit for a while on the charger before i turned it on, but it came charged already. So far i have not let my nexus drain to 0% and the battery life on it is great, it can go for a entire day.

I too just got one. May be came out of the box with 4.2. After I signed in I checked for an update manually, and it immediately upgraded to 4.2.1. I then rooted immediately! Battery has been impressive so far.

No luck for me i guess it shows that there is an update it downloads it and boot into recovery attempts to install but then an android robot laying down whit his chest open and a red triangle appears ?

Sounds like it may be a corrupt download. Unless you plan to remain on the stock ROM just unlock/root it and then install what ever ROM you like.

It happened to my device yesterday too. But after that upgrade disappeared so i can't get update. Did you redownload it? If you did, can you tell me how can i?
EDIT:
I found website for to redownload way (i can't share url because i haven't 10 post) and i have tried twice but every time android robot laying down whit his chest open and a red triangle appears and i can't update. Can someone know why it is happened?
Today i want to work and put the device in a drawer. never touched it during the whole shift but one phone call. during a five hour period 30% of the battery was wasted. bbs showed audioout_2 wakelock took place for 5 hours. screen time was 30 minutes. I haven't kept any screen shots from bbs but i did capture on system battery usage.
what could have caused it?

STOCK EVERYTHING .
not even rooted or bootloader unlocked. An out of the box Nexus 4 16GB (301k),.
Perhaps there's a corrupted media file somewhere in the storage system.

I have no media files on my storage, all my music is via GOOGLE PLAY.
(the wakelock is not caused by google play because since I booted the phone I have not listened to any music)
There seems to be a fix for the problem, haven`t used it myself though. Link http://forum.xda-developers.com/showthread.php?t=2050252. Its a init.d script at boot and you need root.
I wish to avoid rooting my device. when I bought the nexus I wanted to have a vanilla Google experience.
Also I don't wanna void my warranty.

Not rooting a Nexus is like forbidding the Pope to pray But to each his own.
Yeah I know, I think I'll root if i hear reports that rooted devices can receive official google updates

Look here for flashing OTA`s when rooted http://forum.xda-developers.com/showthread.php?t=2145848.
and what of the audio out 2 wakelock? I'm still getting high wakelock times because of it
Sent from my Nexus 4 using xda app-developers app
I remember one time, I left a game without closing the game. 5 hours later my battery dipped and I tried to figure out why. I realized that the game was still running in the background and drained a good 30% of my battery because of the mediaserver. I know it was still actice cuz when I hit recent it picked up exactly where I left off with no lag jumping back into it.
I'm guessing the game isn't coded to freeze in the background when you leave it. I could be wrong, but this is one possibility I think.
I'm on PA, with the matrix kernel. The game is called PAD in case anyone wants more info. I say, just be sure to exit games or generally certain apps when you finish playing them.
This only happened once and since then never again since I started closing that particular app correctly. Also, I don't mess with any music volume booster mods. Just get some noise isolating earbuds/headphones. The volume booster mods definitely killed battery much quicker than it was worth with my first nexus 4
I close everything and still got 1.5h of AudioOut_2 and AudioOut_3 wakelock overnight . 20% battery drain overnight. normally my battery drains 5-6% overnight.

Maybe there is a corrupt file on your phone, it doesn't have to be music, could also be a ringtone or a video.
considering you don't want to root I would consider factory reset then reinstall 1 app at a time until you find the culprit. I know it's time consuming but it's either that or keep your charger handy

Just wondering if this seems right. I'm a pretty heavy user, and sometimes I have pretty good battery life, and then other times I'm charging twice a day. Running plain ole non rooted stock.

I have the same issue as you
Sent from my LG-D802 using xda app-developers app
Since you're rooted I would download Greenify from the play store if you haven't already and use that. It will help. Also GPS from Google Now gives a lot of wakelocks and drains the battery a decent amount. I would turn off your GPS whenever you're not using it.
I'm not rooted. And I do actually have GPS turned off. I also have a lot of things that I don't use disabled.
I want to root, but can't at the moment because of lack of computer..
My search for a computer less root option is a constant failure.
Sent from my LG-D800 using xda app-developers app
You probably get these all the time so apologies.
I've done the google and the msm_hsic_host is referenced for when you connect the phone via usb.
But the problem I have is it's there all the time, regardless of using a computer USB cable or using a wall charger.
These appear far too often, reboots help but there seems to be something wrong and I cannot figure it out.
Any and all help / advice welcome becuase it's really fustrating.
Cheers
What OS are you running? Could it be an app you installed? Have you tried flashing to stock to see what happens?
On stock 4.2.2
Will have to see on the app front.. Might do a purge and see if it helps.
Sent from my Nexus 4 using xda app-developers app
Good luck. Please report back with your findings.
I was on stock 4.4.2 and got pretty good battery life.
Lol OP, I think what you're using is 4.4.2 not 4.2.2. It's time to get it right now, don't you think?
Btw, are you using stock kernel or custom? Either way try flashing stock kernel back and format dalvik and cache. If you're using custom kernel, same..flash stock kernel back then flash your kernel.
Sigh you are right. 4.4.2 of course.
Everything is stock on my nexus4, haven't even rooted it.
Which is why this behaviour is so annoying, might understand if I'd have played around with roms etc.
I've deleted loads of apps, may remove some more today if it doesn't let out. Will then think about going for a wipe down.
Cheers for the suggestions.

Maybe this will help you: http://forum.xda-developers.com/showthread.php?t=1999368
From what i've read, this wakelock is not about the USB cable per se. The 3g modem is connected to the phone as an external USB device, which is controlled by the msm_hsic_host.
In few words, every time your phone needs something from the 3g modem, msm_hsic_host is triggered.
Im on 4.4.2 stock rooted and every time I'm in a place with low signal this wake lock drains a good amount of my battery.
Maybe you should try different kernels to see if that helps.

Using other on better battery stats shows the phone is never in deep sleep.
Now just to find out why.
Sent from my Nexus 4 using xda app-developers app
You need to show us the info from Partial Wakelocks, not Kernel.

Thanks yeah I know that would be more helpful so apologies that I haven't.
Wanted to if possible avoid rooting the phone but I think I'll do that this evening to see what's going on.
