Randomly shutting off

For some reason my sensation appears to have gotten into the habit of randomly turning itself off, and I can't figure out why.
It's rooted, and was using InsertCoin's GB rom for a bit until ICS roms got more stable. I've tried InsertCoin's ICS rom and also Virtuous Inquisition, and had been using the 3.24 firmware. I'm also using an anker battery that's three months old.
I first noticed the random shut downs on the ICS InsertCoin rom, but I'd been using it for a few weeks before it started happening, no apps had been changed or updated at around that time, it simply started shutting off. No menus or dialogs, just an instant loss of power, and could happen at any time, in my pocket when sleeping, in a call, or otherwise active in my hand. Totally random. I could turn it back on, but more often that not it'd just die again within a few seconds of finishing the bootanimation. It appeared to happen most when the battery level was below say 50%. The only thing that seemed to stop it at the time was plugging it into a power source, as then it'd be fine.
Thinking it could have been down to the rom's power management stuff (and me getting sick of the frequent sense reboots anyway), I then tried another rom, Virtuous Inquisition. And as soon as I'd flashed that and set all my apps up again (backups created while using the ICS InsertCoin rom right before flashing the new rom), it ran perfectly for weeks. So that seemed to suggest it was the old rom to blame.
Except recently the random shutdowns have started again, exactly the same behaviour as before. I then thought it could have been the SebastianFM undervolted kernels if my phone didn't like being undervolted, but flashing the regular ones made no difference either. I then found the new 3.30 firmware was available a few days ago, so flashed that. The phone instantly ran a bit quicker and had better mobile and gps reception, and it didn't seem to shut down randomly again. Until today that is.
What the hell could it be? It can't really be software because I've tried different roms, though they're probably based off the same leak. But if it was the rom, why haven't more people reported this issue? I've also tried different kernels and firmware, which haven't helped stop it shutting off either. I've checked the battery terminals and there isn't a loose connection, but could it be the battery itself at fault? Thinking about it, I fitted the anker battery before this started happening, but I'd had it a few weeks before the shutdowns started happening. I've not tried putting the standard battery back in yet as I quite like my battery lasting a day, but I suppose it's worth a shot if for some reason my anker is a dud. Is there any way I could check it?
What are your thoughts? I really want to get to the bottom of it...

Hi,
Do you have any apps on your sd card?
Apparently,this can cause problems.
Go to settings-->apps-->on sd card and untick anything there...

I do at the moment, but I've tried with all apps on internal memory and it made no difference, the shutdowns still happened. In fact I've found no issues with apps2sd on ICS roms whatsoever.

I had the EXACT same issue with ALL ROMS, GB and ICS. Like you it would begin when the battery was below 50% and everything:/ I just sent it to HTC the other day hopefully it gets fixed. And I doubt it was the battery because i was using the stock battery.
I was thinking about opening a thread about this were everyone would post their setup and every detail possible to get to the bottom of this. But i decided not to since it was most likely a hardware problem and would get flamed since there are already countless threads about someone complaining about this.

Well the stock battery is charging back up now anyway so I'll give it a go. I really don't want to have to send it back though given it's rooted, s-off, etc etc. I don't fancy trying to get it back to stock just to see if they might possibly fix it.

same here
Exactly same problem here with virtuous inquisition 3.5.0 and an banker battery...

A few days on with the standard battery, and no random shut downs yet. It's lasting me a day with moderate use too.

I have the same problem before. Sent back to Bell, and they can't fix it. Then I found this app called Captivate Keep Alive. It take a bit of the battery life and ram, but it solve the problem. The phone never shutdown by itself any more. Hope that helps.

damn, this is a good fix but uninstalled because the ongoing notification. I'm not buying the pro version when the developers might come up with a fix in their roms

Same problem here, the problem was more often with the anker battery than with the original battery.
Now i'm back to S-ON and stock roms, it isn't turning off anymore but the problem went over in rebooting...
Only thing i have to do is find an Vodafone RUU for the netherlands , because it was branded and then I will send it back to HTC...
Really annoying... sometimes people ask why they always get your voicemail -> phone turned off in my pocket again...

Unfortunately my issue was the other way round. Mine used to do it below 50%, not when fully charged. It also never happened when it was plugged in. It isn't down to the CPU going to sleep, as I could be using the phone at the time it happened, literally just as if the battery was pulled. Then if I turned it back on it would repeatedly shut off again, until plugged back in.
It's still fine on my standard battery by the way.

my dad on bell is experiencing this issue with his Sensation "4g" lol, with stock battery stock rom s-off stock stock stock.
constantly turning off in pocket, never heard of it happening while in use. waiting for ICS update, if it doesnt fix going for warranty.

Yup, if it's not the original battery, then that problem can happen quite often. Not just phones, it's other electronics also. I had a MacBook, I bought a battery from a third party and the computer shut off randomly. Same with an Asus laptop I bought afterwards and changed the battery.

Ok so I've been having this same problem myself since Christmas.. it started happening on my original battery and on various firmwares ,kernels and rims.. so I bought an anker battery..
It was fine then for a week or two but started happening again.. I read oh about 10 different threads on this subject and what works for me to stop this is switching 3g gsm mode from auto to 3g only.. haven't had a problem while this is switched.. coverage in my house isn't great so I hope there is a permenant fix for this soon

Exactly the same problem.. Turns off when in pocket, hand and even when kept aside .
And Everything's stock. Battery, version etc etc.
Still can't figure out what the problem is.

It can also happen with a standard battery if it's faulty. Get HTC to send a replacement.

Mine is still having it... really annoying, even with the new ICS. Everything is stock now.
I also want to send it back to HTC, but I think they are going to test it first... chance is high that it wont shut off then -> phone back and the problem is still there..... That would be an endless story

have you guys seen this thread:
http://forum.xda-developers.com/showthread.php?t=1475602
Seems kind of silly to have two parallel conversations on the same topic...

I had this exact problem on a stock battery with any rom. The fix that worked for me was changing the network settings from Auto WCDMA/GSM to WCDMA only. It was something to do with transition between 2g and 3g.
Bizarre problem and I hope there is a better fix available soon!
Sent from my HTC Sensation Z710e using xda premium

Not happy, I thought it was the battery but it's started doing it again, even with the standard battery instead.
Just had a look, and on my ics ROM I can't find the option to change the wcdma settings, so I can't try that. Not sure how that could cause it though, because it can even shut off while showing the boot animation! The only thing that seems to stop it is plugging it in, meaning it was no longer using the battery. Hence my assumption that the battery was at fault, but I've tried three different batteries on it now and it happened with any of them. Not much chance that all of them have exactly the same fault.
It can't be a loose connection since if it was I wouldn't be able to turn the phone back on in the first place, so what the hell could it be? I don't think I ever had the issue until going to ics, but I've tried different ROM's and the issue didn't go away. I've tried different kernels over time, and also upgraded the firmware and radio a couple of times too. None of which cured it, so I can't see how any of them could be the cause since it happens on all of them.
Any ideas?

[Q] random power-offs???

Hey guys, I was using the miui rom but after a month or so it just kept turning off repeatedly and whatever I tried didn't stop it. I tried wiping dalvik cache, wipe data/factory reset, reflashig the entire rom but it didn't work so after a while I got fed up so I switched back to cm7 but the phone keeps restarting. Are there any solutions?

try a different firmware?

I've been on the same firmware for months. I can't Change it because I am hboot 1.23

Are you also having problems with the battery level jumping around by any chance?

yes. Unfortunately ........

Well I've gone a while with arhd and it didn't happen but being sense it was laggy so I went back to miui and its rebooted 8 times in one hour.

I'm having the same problems, and while watching my battery voltage graph, it spikes down a lot, which indicates a bad battery, but it might be kernel. I'm downloading the update for virtuous now and seeing if its fixed. You should flash the update as well. In any case, it'll stop those web browser lockups. Looks like a lot of people are in the same boat here, which is why I'm hesitant to instantly assume its our batteries frying themselves.

I'm not sure about this but I just switched back to my stock battery and it stopped randomly turning off. I went about 3 hours use with no turn offs but I switched back to the banker battery and so far no restarts but I will need to see fully tomorrow. I don't think that it is due to overheating,I was in my garage and its ****ing freezing in there. I went to check the time on my phone and it was off but cold and hadn't been used.
Will just have to see what tomorrow brings.

Data doesn't come back on even after leaving a dead zone

So where I live has solid 4G, but, once in a while, I'll go into an area with no data. When I leave the dead zone and come back to my house, the data stays cut off. I've tried dirty flashing the ROM over it again, but that doesn't help. The only thing that has worked so far is to reflash the ROM after wiping everything. If it only happened once in a while, it'd be fine, but I go into the dead zone approximately once a week, so it becomes a real hassle.
Is this common? It's been happening on the Synergy ROM. I would just use Hyperdrive since it has almost the same features, but I've just been getting much better battery life and charging times with Synergy.
Is there a way to fix this? I've been thinking and the only thing I can come up with is when I flash a ROM after wiping, it takes a few seconds to activate my LTE. If there was a way to repeat that process without wiping, I think it'd work.

[Q] Screen randomly goes black

I've been having this problem starting the last couple of days. I'll be using my phone, and all of a sudden the screen turns off and nothing short of a battery pull will turn it back on again. Sometimes it happens when I'm not using it at all too. I'll pull it out of my pocket and get nothing. Do a battery pull, and everything's fine again until the next time it happens. Never had this problem before, but in the last two days it has happened 7 times. It even happens when it's plugged in. The LED indicator that is normally lit up when it's charging will go out. Unplugging it and plugging it in seem to have no effect. No sounds, nothing.
I'm running Jellybeans 4.1.2 Rom, with TWRP. Today I ran a backup, cleared and wiped data, fresh install, recovered backup and still having the problem. Should I try a clean install without recovering the backup? Could that have anything to do with it? Any other ideas on what to try or what the problem could be?

If you've been running the same ROM this whole time and it just started out of the blue, I don't really think it would be ROM related. It might be hardware related.
I suppose the only real way to test if it is ROM related is to ODIN back to stock and see if it still happens. If it does keep happening once returning to stock you could probably get it swapped out by Verizon.

I've been running the ROM a lot longer than I've been having the problems, so I suspect you're right. I've had the phone for over 2 years now, so there's no warranties anymore. If it really is a hardware problem I'm probably looking at a new phone.
I'll try going back to stock though and seeing if it changes. Thanks!
Update: I just flashed did factory reset and flashed back to stock, but can't even get through initial setup before it goes black...guess it is hardware.

Frequent Reboots. Please Help

I have been using Cyanogen for at least the past year. In the past I have had trouble with things like random reboots, maps crashing during navigation, etc. Because of this I switched to just running the milestone releases for the past six months or so, and that has worked reasonably well. Its still way buggier than stock, but I put up with it for all of the nice features and what not.
Lately though reboots have become more and more frequent even though I hadn't changed anything. I had been running M9 for the past month with no real problems and then last night it decided to just go into a boot loop. I tried pulling the battery, clearing the cache, clearing dalvik, nothing worked. Eventually I just let the thing boot loop all night long and when I woke up it was finally booted.
Then this afternoon it did it again for a short period of time (3 or 4 minutes). When it came out I decided to download the newest, M10. It took several tries to actually flash it because the phone would reboot iself while in the middle of the wipe, or the flash, etc. But I started the wipe/flash process from the beginning every time to make sure I had a clean flash and eventually I got all the way through. But now it is at a point where it will boot, sit there for 2 or 3 minutes (I don't even touch it), and then reboot.
I'm hoping someone can help. I'm holding onto my unlimited data for dear life... I don't want to have to get a new phone. But re-flashing doesn't fix the problem so I really don't know what to do.

I don't know why your having such an issue with cm. Which is odd because I'm running a rom that's CM based and works fine. I'd say maybe try another rom if for nothing other than to see if CM is truly the issue.
I praise you for having the unlimited data still, I wish I would be been smarter and kept mine because there are months where I'm a little too close to that sad but lack of data with 2gb
And my hometown is Syracuse NY as I see your city is there. I miss the cuse but not the loudness of the city

Pull a logcat or use a tool like https://play.google.com/store/apps/details?id=com.tortel.syslog to do this for you. then after the phone reboots itself, run syslog and examine the last_kmsg and logcat to see what the obvious errors/issues are.
I too have noticed google maps crashing, camera unable to connect, random reboots, file system errors, sluggishness, etc more lately with my G3 too. Wonder if some aspects of the hardware are failing...

You mean freeze the stock camera and use the Google camera instead?
Yea, when the camera is broken, neither app can connect until phone rebooted. Already tried many a time.

These symptoms could indicate a sticky power button. Try knocking it lightly against the corner of a table to jar whatever is making it stick loose.
It doesn't sound software related, especially since it rebooted while in recovery. If you hold the power button down long enough in recovery it will reboot, which makes me think you just have a sticky power button. It's happened to me before.

I think you might be right. Even when it is up and running, I have been noticing lately that I get the power menu popping up sometimes when I wasn't even touching the power button. So last night when it was in one of its constant boot loop fits I took it apart a bit (took the back off, took out the battery sim and sd, and unscrewed the shell) and blew some compressed air all around the power button. It had been rebooting for about an hour at that point and then as soon as I put it back together it came up on the first try. So far so good.
