Official HTC EVO Random Reboot Thread

From searching, it looks like tons of people are having random reboot issues with the HTC EVO. Let's make one thread to put everything so maybe we can figure this out.
Side note, it looks like the HTC desire has the same issue:
http://forum.xda-developers.com/showthread.php?t=676402&highlight=rebooting
So post what you've tried that hasn't worked.
If you think you have a solution, share

One thing I've noticed is it seems heat related.
I've installed temperatures monitors and it seems around 32 degrees Celcius is around when it reboots. It will reboot loop usually. This can be cured by pulling the battery and waiting for it to cool down, or just put it in the freezer for 4-5 minutes.
I've tried underclocking it with the screen dimmed way down, and running it without the back cover and it still overheats.
For me, the problem came out of nowhere. I had the device for over a month with heavy usage and no problems. My current GUESS is it must be a physical problem. Not enough thermal grease or something...
It looks like the HTC Desire users may be getting replacement motherboards to fix their issue.
Does the HTC EVO and Desire share parts?
From other threads it looks like:
Root or Stock - Doesn't matter
Radio version - Doesn't matter
Rom version - Doesn't matter
GPS Fix - Doesn't matter
GPS turned off - Doesn't matter
3G data, 4G data turned off - Doesn't matter
Hard Reset - Doesn't matter

Found this on the HTC Desire reboot thread:
Latest test list for HTC Desire RR (Random Reboot) problems:
-All phones with s/n HT03 to HT07 can get this problem (Minor problem from SH09 so far)
-Starts around 1.5 to 3 months after use
-Reboots get worse over time
-Firmware and android version doesn’t matter which you have
-Force apps2sd doesn’t matter if you use it or not
-PVT1 or PVT3 or whatever doesn’t matter
-Screen type, doesn't matter if you have AMOLED or SLCD
-There seems to be an antenna/radio/simcard issue also
-Overheating causes reboots too
-Reboot is not always temp related
-SD card size doesn’t seem to matter
-Having apps on SD or not doesn’t matter
-Size of files on SD doesn’t matter
-Rooted or not doesn’t matter
-Motherboard changed after repair doesn't always fix it
-Sim locked or not doesn't matter
-Provider doesn't matter(vodafone, kpn/hi, T-mobile etc all got it)
-Most likely hardware issue, sense flashing won’t fix it, yet changing motherboard will
-Restarting doesn't fix it
-Factory resetting doesn't fix it
-Changing/buying new battery Doesn’t fix it
-Using app killers or shutting down some services yourself doesn't help
-Leaving all settings on default doesn't fix it
-Plugged into car charger in the past doesn’t matter
-Hboot version probably doesn't matter (still not fully tested)
-Having a phone cover or not doesn’t matter

wifes phone has been doing it very bad...one that has never been rooted...
was going to root it and try new rom but seems to be a hardware issue.
any other comments on this subject?

My stock rooted Rom just rebooted for the first time today. I really don't rememebr what I was doing st the time....but this has never happened before. I assume there's no event log to check.

I had been facing this with increasing frequency. I got the phone on launch day, and the problem started over the last month, getting worse all the time. I agree with the OP that there does not seem to be any obvious cause -- sometimes it is heat related, sometimes not. Any time I push the phone (run psx4droid, or navigation + anything else), and sometimes even with lighter usage, like on a phone call. Unrooting did nothing to stop the problem.
After extensive searching, I found three possible causes: bad battery (I tried a new one and the problem continued, but this seems a good starting place), bad memory blocks, or bad processor.
I was unable to find any solution to this problem. I took my phone to Sprint today, and they told me that their tests didn't show a problem. Then I made it happen in front of them (launch navigation to anywhere, then a couple more apps, then boom, reboot) a couple times (really, after the first time, letting it turn back on pretty much caused it to happen again).
After that, they agreed to replace it. I do have the TEP, but they assumed that the problem was hardware related so I don't know if you have to have it for them to replace it.
Strangely, they gave me a white one as a replacement.
I haven't had any problems with the new (well, re-manufactured) one, and I hope it stays that way, but I guess only time will tell.

I'm currently experiencing the problem as well, funny thing is every time it happens, the phone is NOT in use, simply sitting on table or desktop in standby. This happens about once every two days.
Currently running rooted evio2 1.3.1

Wow, I was about to start this thread, when I saw this. I guess I was like 10 minutes late. Either way, i believe something messed with the hardware. My little bro cracked my screen badly, so I am getting a new evo anyway, but will I be able to get one free bcuz of this? This is really a terrible problem. Somebody needs to de-assemble their precious evo and see if there is an obvious problem. thanks a bunch. Subscribing.

same here.
happens mostly when on the charger and i am using it at the same time. so heat related seems likely.

can anyone get a logcat of it happening?

I called sprint support and they said it's defective to return it.
Taking it in for replacement today.

Sprint replaced mine for $35 [a refurb]. That's the end of that.
But now, I can only use the speaker to hear my callers. Gotta go back and get another!

My guess is the new update could be putting a lot of strain on the battery but who knows? I haven't experienced it but maybe its because I'm using the extended mah 3500 seido battery.

No, I've got the 3500mAh Seido battery too.
I don't think it's strain since mine has gotten worse. AKA the amount of usage it take to make the phone reboot has gone from hours of use to minutes.

Actually I just had a reboot lol.

Same thing here. I posted my issue in the rom threads i used, and everyone ignored the issue, lol.
For me, I noticed it about a week after using roms with the new software update (3.29). It happened with navigation, launching multiple apps, running quadrant, etc.
So yesterday I installed DC 3.5 from scratch, turned nav on and let it sit for a couple of hours. NO reboots. Before, after 10 mins of the screen and nav being on, I'd get a reboot. Has anyone else tried this (or willingly to try it)? I switched back to my nand backup, ran quadrant -> bam, reboot.

I bought my EVO on launch day (HW Version 002), and have not had any problems until around Oct 13.
I took the phone on a trip to Orlando, and as soon as I got off the plane and turned on the phone, the problems started happening. It has been happening ever since, even since I returned home.
I bought my phone at Best Buy, and have had their Geek Squad send it back to try to fix it. I also added the complaints about screen separation to the workorder so that they would be more likely to replace the device. Hopefully, this fixes the issue.
I also think it is heat related, but I don't know why it is just now becoming an issue. Just to make sure the folks at BB could see the issue happening, I put the phone in front of my car's heater for a few minutes, then started up Google Earth, and was able to make the phone start boot looping while I walked into the store.
I tried hard reset, soft reset, update prl, underclocking, GPS Reset, new battery, new SD Card, and none of those things worked. I wonder if the removal of the 30 fps limit in the last update caused some type of heat damage?

I just had a reboot last night while trying to look at a picture I'd just taken in the Camera app on CM6.0.0. Only the 2nd or 3rd time it's happened. Still annoying though. Hope it doesn't get worse.

I reset mine back to stock. Unrooted it and everything.
Didn't fix the issue for me.
Now I did try erasing all the stuff that's erasable inside recovery and it seemed to go a few days without a reboot. Not sure if that was a fluke or not.

[Q] Defy T-Mobile boot loop how do I fix

I've reviewed some solutions on here regarding the UK rom version and loading it to the device. My concern is for the warranty on the device does anyone have the T-Mobile rom available to load on the defy? I'd assume that'd fix my issue where the phone has a boot loop and a wipe is not fixing it. I tried talking to motorola and that was a complete fail (see conversation below).
Reymer: Hi, my name is Reymer. How may I help you?
James: i am using a motorola defy. all of sudden today it stopped working. it boot loops showing the motorola boot screen and tmobile screen but then keeps doing this over and over again. i tried to do a factory reset but still failed. is there anyway for me to manually update with the original rom again with an update.zip similar to the motorola cliq?
Reymer: I am sorry to know that.
Reymer: Are you referring to a bootloader screen?
James: not exactly. it acts like it's booting up as normal but keeps repeating the process. i help down the volume and pwr button to get to the other screen can't remember what it's called so i can attempt a factory wipe on the device.
Reymer: Can you please take out the battery, return it after a few seconds and turn the phone back on? Let's try to see then if the phone is still doing the same thing.
James: i tried that already. still the same thing.
Reymer: Were you able to use a different battery?
James : why would a different battery change anything if it's software related? i know from all the research i've done so far it's needs to software reloaded to it however i cannot find the software for this device on the motorola website. it's a tmobile usa phone.
Reymer: We need to determine first if it's a phone or battery issue.
James : okay but explain to me what the battery has to do with the phone software? that's like telling me to put gas in my car to fix a flat tire they have nothing to do with each other.
Reymer: How did you know if that's a software issue?
Reymer: We are doing every means to isolate the case.
James : because it powers on and starts to boot up but just boot loops it doesn't power off. the battery is brand new and has a full charge i got the battery today so i know it has nothing to do with the battery. i've also worked with android development and understand isolating the issue checking for hardware concerns first which i did prior to getting on this chat.
Reymer: I suggest that you send in your phone at our repair facility and have it evaluated by our repair technicians. If proven that it did not suffer physical or liquid damage, that will be repaired for free.
Let me just inform you of the repair time frame, it will be 5-7 business days from the date we receive your item before it will be sent back to you.
Reymer: All Motorola phones and accessories have a standard one year warranty barring physical or liquid damage from the date of purchase.
I ended the conversation after that

Use my debranding/debricking guide in the dev section. If you are a US customer you will lose 3g and wifi calling as the US firmware is not available at present so you have to use UK - there are fixes for this about.

My first response to your phone call is... well, when I'm asked to do something absurd with my gear (and why would you have an exta battery anyway?) I always say, "yes, done that." "Have you tried jumping out the window with the phone up your ass singing "God Save the Queen?" "Yes, twice. No go." However... there do seem to be some whacko battery issues related to rebooting issues on Motorola phones. Example:
"I just got a new battery for my Droid, and the battery came 60% charged. So I did the battery drain until it powered off. I then put it on the dock to do a full charge, and now the phone is in a constant boot loop."
Same guy then:
"I just tried the old battery, and it does not go into the loop with the old one."
So..?

As far as I know, Li-ion batteries hate depletion, they shouldn't be totally depleted.
"Depletion below the low-voltage threshold (2.4 to 2.8 V/cell, depending on chemistry) results in a dead battery which does not even appear to charge because the protection circuit (a type of electronic fuse) disables it." -

Not sure what you mean. That a bad battery can cause problems? That IS the point, even if it's something produced by the user. It's probably not the cause, but it might be worth a try? This rebooting issue, though not tiny, does seem to be limited to some Euro (UK?) phones. Maybe a release of a bad batch of batteries? I realize that that poster probably should not have depleted his battery (though... don't we all once in a while?) maybe by crapping out his battery he induced his re-booting issue. But that still could be the cause of others' problems.

Hi !
I have this problem too.
My Defy always reboot in loop
This is a french Vodafone branded phone with Blur_Version.2.21.0.MB525Blur.Vodafone.FR
The only thing I see is when I received the phone I started it without charging the battery.
I know that was noticed in big font but i was hurried and didn't think that can be a problem for the battery

every body i need help.

[Q] Random rebooting, kernel panic - got my one x

Hello Guys,
so i got my new one x yesterday and im not very happy with it.
1. It does some random reboots, just lying around and reboots sometimes.
2. Phone "hangs up" with black screen and blinking buttons. As far as i know this is a "kernel panic"
This happened about 5 times now, last time as im writing this.
3. Battery drain is huge, seems like a result of the above problems. Android OS has about 90% battery usage and it dropped to 82% after 54mins without charging and just lying around.
On the both screens you can hopefully notice it, 26mins and it lost 10% battery.
After this kernel panic the battery drain changed and the Android OS stopped to drain so much battery.
This is the "out of the box" state of my phone. I changed nothing beside from charging the battery and installed some apps (normal stuff, angry birds and such).
Does someone have a idea about this? I hope or assume these a software related problems. But im not sure with the kernel panic thing can this be due to hardware issues? Should i ask for a replace?

You said you installed a few apps and games. Try going back to factory settings first, wait a while and see if the pattern repeats, if the phone behaves normally, then it must be something you installed, not all apps are optimised for ICS.
Good luck!

check your kernel version pls

Ok thanks for your first impressions and help. Im trying the factory reset now.
I have done a screenshot of the kernel version.

First of all, and probably most important is to leave your phone charging for 6-8 hours without turning it on.
Then its spend the battery time where you do whatever it takes to.empty the battery completely until the phone is ready to shut down. Shut it down. Repeat charge process from above with device off. Turn it on and then you can be ready to test it for real. As far as reboots, you really should let the system settle down a bit. Give it a day or 2 without some extra heavy usage and I'm sure it will be just fine.

i hope this isnt a joke

joke or not, normal stuff apps can cause problems. the whole Android OS battery usage is because of apps you installed. it's a brand new phone and i wouldn't be too worried about it. i switched from Samsung to HTC because Samsung releases broken source code and doesn't seem like they really know how to do anything but stick hardware together. if i'm not happy with HTC, then maybe Motorola is making the next Nexus phone and i'll give that a try.

Please do keep us updated on how's everything working out ? Did the factory reset solved the issue? Hope this ain't an April fool joke ! Anyways hope everything goes well for you mate. Kept my fingers crossed on mine one x

So ok, i tried the factory reset twice. Seems Not to work atm. Im going to try it again. I hope Arhd and s-off is working soon
Im curios, maybe there are more ppl with this Problem after monday / tomorrow.
Ill keep you up2date.

Return it.
There's no way a factory-reset device should be behaving that way. My guess would be hardware problems.

First wave of a new phone is always more risky, you can get a faulty device

Agreed, it sounds screwed to me.
I can't speak for the rest of the world - but I don't really know why people panic. If the phone ends up being unstable it's going back and they'll be refunding my contract - it's really that simple.

There was a similar problem on the original Desires. Linked to overheating especially with GPS.

I'm not going to say your wrong but could you post some evidence? Ok the first part is per the user manual so I will agree with that one. However there should be no need to empty and re-charge the battery should there? According to this site: http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table Deep discharge wears the battery down. It also says no priming is needed.
Then the second point letting the system settle down? what? let what "settle down"? I don't even understand this statement. If you explain what you mean and again if you can provide some evidence that would be great. Thanks.

same problem
I experience the exact same problem. Random reboots and crashes.
What did you end up doing?

same problem too
Me too.
Get the phone for 2 days, and randoms reboots.
Get the same kernel that Dreist.
Try yesterday a factory reset, but no change.

I have the same problem. Constant reboots out of the blue. I'm back on my nexus which is super reliable. Probably gonna return it.

Got 3 reboots in a row yesterday but it was after flashing bricked kernel and battery under 23%, plugged the AC cable and no more reboots,perhaps the battery level is false with bricked kernel...

Just swapped mine out for a new one but now the new one has a yellowish screen. (sigh)

Random shut downs?

Hi guys. Haven't been here in a while. My daughter is now saying her cap. glide is randomly shutting itself down- not related to low battery. It happened 3 times in one week. When she powered it up the battery was fine. The phone is about 9 months old. I think it has a 12 month warranty. At least on the samsung site it says 12 months. We got it from ATT with contract renewal.
I read that the regular Captivate had this problem. Did it flow over into the glide? Haven't found anything about it. I assume ATT will replace with a refurb if anything.

I use mine pretty heavy and havent noticed any problem i assume that you are running the phone completely stock and if so i would suggest that you download samsung kies from samsungs site and run it then plug the phone in and it will ask you if you want to update the phone it may run better on the newest firmware that there is other wise i would download avgs free antivirus app and run it to see if there are any apps that might be to blame i would post links but to avoid spam i am not allowed

Thanks for your response. Yes, it is stock rom, but I have it rooted with CWM recovery on it. I don't think kies can update it due to CWM. And it's in another state. LOL. But good to know you don't have the issue. As for running antivirus, my daughter does not even know what that is- she barely runs it on her computer. If I ever get my hands on it I will try your suggestion for AV.

Could be a battery issue... mine did the same, and when I took out the battery it was slightly swollen.

Thanks for that. I'll have her check it out.:fingers-crossed:

Interested in your solution
My wife's Captivate Glide just started having random shutdowns last week. I came over looking for a "return to stock" thread hoping that putting a new OS might help when I saw this thread. I've been reading xda on the GalaxyII boards since getting mine last year so have some familarity with xda. Wife prefers to not update OS so I want to avoid ICS. She had AVG installed and I added Lookout to scan with it also and can't seem to find an issue with those. The problem for her mainly manifest itself when she has the internet turned on. The phone will basically act like the battery is critical and do a shutdown even if it is over 50 percent. power up with the cord in and it still shows good charge. If I find something that works I'll post it here also.

I have random shutdowns/boot cycles too. I've narrowed it to a hardware issue. I was running rooted stock rom, but also ran liquidsmooth and now on aokp rom, and its still happens.
I posted a topic a couple weeks ago, asked if anyone has any experience replacing the power button..its not that it sticks, but if pressed the wrong way in the wrong spot, the phone goes into endless boot mode, with the samsung logo up for about three sec, then black, then samsung logo, then black.
The timing is rarely the same. There's no debris or gunk. Its not battery. Its not overclock issue. Its something to do with the phyical power button.
Can I diasble power button using key remapping?

Having the same problems with my Glide, and I really do think it's a hardware issue since my battery looks fine. After reading many threads here and elsewhere, I'm resigned to the fact that it can't be fixed, but more suggestions are welcome.

My daughter has had this phone for almost a year and it just started happening to hers. She is very hard on her phone. 5000 texts/month with alot of drops. She just might have abused it to near death. lol.

Random Boot
Hello guys;
I think I'm having same or very similar issue.
My phone is randomly shutting down; some times is in cyclic restarts.
Did you guys came up with a solution to this problem?

5000 texts per month?
Does your daughter know how to speak or is she only familiar with written language?

If you're on a stock rom, it's almost certainly a bad battery.
Battery voltage will drop when it's hot or if it's damaged. When you turn it back on, the phone says you still have plenty of power left.
What the phone is really doing is making a guess about how much battery life it has left.
It knows the voltage. Now, if you know the voltage a battery is producing with no load, you can get sort of an idea of how much more life you can get out of it. The phone keeps track of this (roughly) and tries to guess. It's also not going to let the battery drop too far down below 3.6 volts, it will shut it off for safety, because if you truly completely discharge a lithium battery, you can't charge it. (there are tricks to get them going again, but it's bad for them.)
And a damaged battery can have plenty of volts, but once you put it under load it will drop sharply. The phone will power down to protect the battery, or it just won't be able to stay on any longer.
Anyway, pull your battery. Make sure it isn't bulging. Pick up a spare off of ebay for $10 and see if it is better.
Or if it's under warranty, just take it in.

Lol.... Sometimes it's only 3 thousand. But you are right. The art of communication is being lost on this generation of kids who rely on computers, tablets, and smartphones. Instead of calling, they text about everything.

It's also not going to let the battery drop too far down below 3.6 volts, it will shut it off for safety, because if you truly completely discharge a lithium battery, you can't charge it. (there are tricks to get them going again, but it's bad for them.)
And a damaged battery can have plenty of volts, but once you put it under load it will drop sharply. The phone will power down to protect the battery, or it just won't be able to stay on any longer.
Anyway, pull your battery. Make sure it isn't bulging. Pick up a spare off of ebay for $10 and see if it is better.
Or if it's under warranty, just take it in.

Very informative. Thank you. She did pull the battery and it was fine. It is about a year old. I got her 2 replacements and she just doesn't use them. I will suggest that she switches to a new one- although they are almost a year old too, but unused- I charged them up once before i gave them to her.

phone saga continues!!!
:silly: Well, my daughter being sooooo poor that she couldn't buy herself a BOX of tissues(cough-cough), she was pulling toilet paper from the dorm bathroom and plop! OOps!! Her phone fell into the drink! (toilet bowl!!)
She knew enough to pull the battery and used a blowdryer to start the dry out process, and put it into a bag of rice. Didn't leave it in long enough and tried to power on- did a little dance, and it died. I thought she fried it, but she put it in rice again- battery pulled and slid in the open position.
2 days later she called us on it- (today) and it seems to be working!!!:victory:
So, Rice saved the day again! :silly::good::highfive::fingers-crossed:
We'll see how long it lasts. I bought a cheap go phone last nite on att for $21 as a temporary replacement. Maybe it won't be needed.

Help!!
Hard to believe my glide is begining to give problems. After flashing a stock kernel on spike55 jb 4.2 rom,i started getting random app crashings. So i sought to revert by flashing back the original jb ROM,but it got worse. Now i was uable to get network and my baseband version displayed unknown also i had random reboots.
At this junction, i realised i had to revert to stock. So i got a stock ICS rom from sammobile, flashed it via odin and whala! Problem seemed solved. So i flashed CWMR and reflashed jb 4.2.
Afterward, all seemed well not until the random reboots came back. So here i was thinking about my phone being tired of all the flashing and wanting to be on stock. I went back to stock, but the random reboots still lingers.
Though i have a feeling the problem is with my power rocker cos only a little tap pops up the power menu.
At this junction, i dunno what to do. I'll be very grateful if i can get any real assistance from anyone. Thanks a bunch in anticipation.

So I thought I'd post again. Daughter home for good. Started complaining about her battery again. I found her 2 spare batteries that were never used. Had her make the switch.
Then I looked at the removed battery. It was slightly swollen. You had to look straight down to tell. Looking at it flat, it seemed to be fine. But put it on end and it had a slight bulge. So it was a battery going bad. We caught it before the phone was damaged.

Hello!!! Back again My daughter ran on macadam and her unprotected cap. glide plopped out of her sweatshirt pocket and hit hard. A small hairline crack in the screen, but it pretty much killed the digital panel. She had it for 18 months and for her, that's a record. But she loved the phone.
We just got a new one unlocked one off amazon for $138. No contract renewal for her.
If anyone is still reading this thread, her OS is 2.3.5 or 6. Is it worth updating to ics? We don't have kies installed so it will be a job to get everything installed, get drivers working, etc. She will be happy with GB. Last time I made the change to swap external and internal sd cards and she had no problems.
So is ICS worth the effort? Battery life? Can the sd swap trick work? Any advice will be appreciated. Presently it is new and stock.

..it might even have come with ICS, the UI differences to GB are very slim.. Can't say more because stock roms are far inferior to the beast called P.A.C.man ROM :laugh: :good:
Really depends if she is tech savy and will explore the depths of customizability and usage... If so, http://pacman.basketbuild.com/index.php?dir=main/i927/nightly/ is the next place to go
Nightly builds 'been broken for 10 days now but should be fixed soon by awesome @kick buttowski :good:
And on a rooted phone, Titanium Backup can import/export SMSs and contacts supposedly even over to a different rom. (Still struggling a bit getting all my contacts ported from the sony xperia system, but..)
Oh by the way, one of them plastic hard cases is about 5$ on the bay
...It's not water proof though

Nice to see people are still using this phone. As far as the case- I must have bought 5 of them for her. She didn't want them on her phone. Now that she paid for her own replacement, she may rethink that one! lol. She is not tech saavy at all, so custom builds are not her thing. I didn't even do the mods on this phone that I did on her original. Thanks for your input. OH, it's still GB.

[Q] Huge Battery Drain but no wakelocks

How is that even possible?
I have attached 2 screnshoot of a Galaxy Nexus battery drain.
My phone is 100% stock, I just restored the nexus official image. The battery should be new, I already sent the phone to the manufacter last month and I think they changed the battery.
I didn't even setup a google account, no app installed, wifi off and there is good signal.
There are no wakelocks. Screen was off all the time. The battery just go down.
(Some translation. Segnale rete mobile = mobile network signal, Attivo = active, Schermo Acceso = Screen on)
What should I do? Call samsung again and stay another month without my phone? Is there any other solution?

Well, for starters you could let it charge for another cycle or two to be sure about.Also I see the Network reception is not so good.That may be responsible for the drain, though I highly doubt it !

Yes, I'm trying to do some complete charge/discharge.
I have similar result in Airplane mode, network reception is not the problem.
Thanks for the answer. :good:
Anyone else with some advices?

No one?
I don't want to spend another month without my phone because of RMA :crying:

I have the *exact* problem (or at least, similar).
I have RMA'ed my phone 2 times, teling me they had done a "mechanical repair" (in Italian, as per repair center label, "riparazione meccanica").
Don't ask me about the meaning of this. It could be everything, but one thing is certain: serial number of the phone is the same, so they did not change the motherboard at all.
Back to topic, I'm experiencing serious issues:
1) huge battery drain in airplane mode, even after complete stock and several ROMs (the service center restored 4.0.4 on it, funny)
How did I test: the day I received back my phone, I have simply fully charged it, switched to airplane mode overnight and I have lost more than 30% battery with NOTHING at all installed, I even left the wrong date/time !!
2) before RMA'ing it, it did not matter if I used 3G / WiFi or nothing at all: I always got a similar battery discharge curve.
BUT today I noticed something odd:
while testing for the (1) issue above, I noticed that the "Awake" (aka "Attivo") bar under the battery graph was pretty full blue colored, which is NOT normal actually. How can it be after a full wipe (or so, as per after sale service) ????
Let's try to troubleshoot this problem guys, because I'm really fed up
...and I don't want to sell this Nexus, I simply love it hehe
TODO:
1) Wipe and test again -> charging the phone right now
2) analyze dmseg (maybe there is an hardware issue that keeps interrupting the CPU) -> after a quick look it seems that actually my interrupt idea could be true ( "Resume caused by IRQ 39, TWL6030-PIH". This is the power management unit) but I have to see during the airplane mode test, not while charging (that might be correct)
3) measure the current and compare results against a nice study of another guy (that reported power consumption on different scenarios)
4) ??

The same. They changed the battery in my case. I did a mark with a marker pen on the battery before sending it and the mark is not there after RMA, so they changed it. Phone serial is the same.
They also put 4.04 on my nexus, what a shame!
I did not experienced the "active" thing on the battery statistics. I had several wakelock from "RILJ" but after a full restore the disappeared.
I restored (again) the phone with nexus image, and even locked the bootloader, removed the sim card and disabled wifi, gps and everything. It always discharge by itself in a too short period of time.
Is there something I can tell to RMA to make them change my phone? I don't think it's a software problem.

I agree, this must be an hardware problem.
To say, I have tried a long list of ROMs and kernels, as well as updating radio and all other sort of stuff.
Now the awake "problem" has gone, so today I'm gonna retry the (1)st experiment.
Let's see...
In any case tomorrow I'm going to go to the shop and ask them if they could be so gentle lending me a fresh battery to test out.

Some clues here?

I don't know if it might be related or not, did you ever use tethering?
Pernsonally speaking, yes I did.
Today I try to wipe radio and flash another one...

No, I never used tethering.
My phone is at RMA again, I asked to fix it FOR REAL, I'm just hoping.

I've had a similar experience since first getting the phone. While with light usage, I used to get anywhere between 16 hours to a full day of battery life, I'll only get between 4 and 6 hours of screen-on time. Whether full stock or ROMs, it's always been the same. I've eventually just chalked it up to hardware being the issue and made sure to always have a spare battery and charger with me at all times.

I got my phone back.
They said that they changed the motherboard. On the package the note is "sostituzione board unit".
In the next few days I am gonna do some test to see if they really solved the problem, I really hope so.

Nice to hear
Today I was suprised of my phone's duration (still no serviced again): more than 1 day (of course without doing much) and only 10% drain during the night.
I don't know what happened BUT i can say also that I'm experiencing now a problem with the network (GSM, 3G): the network crashes sometime also while calling or while idling.
Today it did not crash in a > 10min call, so let's see also the battery drain during this night
...because strange stuff happens!

try update to the latest new radio.. flash radio.img
galaxy nexus i9250

I think that the problem is solved.
It was a hardware problem.
I'm on CM10.2stable now.
Latest radio and bootloader.
Now my phone last enough .
I called Samsung a lot of times to urge them to fix my phone.
EDIT: I'm now on 20h20m on battery with 3h23m screen on and 4% left. Goood
