    Default Automatic shutdown for no reason

    Hello everyone,

    Before stating my problem i want to thank everyone who participates in finding a solution, your help is greatly appreciated .

    Well here's the problem, I have my HTC sensation for little over a month now, and up until four days ago there were never any problems whatsoever aside from normal use issues. But since then I have had several occasions upon which the phone just shut down for no reason. Four days ago it was the first time, and from then on once a day. But yesterday it shut itself down for THREE times within four hours.

    This is becoming quite the nuisance since i can't recall having installed anything that could cause this nor have i dropped the phone and I don't know what the problem could possibly be, I've thought it might be a battery issue or something?

    Maybe this helps as well, but the shutdowns appeared to be during the same time of day, namely from 16:00 to 21:00, never before or after this period (but maybe this will change in the future).

    Well, these are the facts, i hope someone can help.

    Kind regards,
    Silas

    Indeed i recognise this problem. I was firstly suspecting serveral app's i downloaded before the first random shutdown (the shutdown occurs when my phone is lying on my desk doing nothing but the background stuff it always does.)

    I deinstalled all the suspected apps but with no avail.

    At the moment there is an update pending that im going to download to see if this helps.
    It could be a background problem, so one way to test this is to shutdown all synchronisation settings for 1 or 2 days and only use the phone for calling and texting.
    If no shutdown occurs its an application fault.

    If the shutdown does happen, it has to be a hardware or Android systeem problem, updating could help, otherwise this must be reported to HTC to see if they can fix the problem.

    another option is to make a full backup of all your data and place back the factory defaults and wait 2 weeks before you start installing apps to see what happens (time dependent fault is also possible).

    I have now deleted all custom applications (no 3rd party app was downloaded) and have the following left:
    HTC Sync
    Music shop (From my provider, android is also provider branded)
    Shop (provider)
    teamviewer
    updates (provider)
    whatsapp

    All these applications should be able to work on the phone without problems.
    I'll let you know what happens!

    Some deleted applications:
    Winamp
    3G watchdog
    Free chess
    Bunny shooter
    Angry Birds

    I will leave the phone off the cable so i can later test if it happens when its on a cable.

    I have put the phone back to factory default, but this morning ot happend again.
    I am suspecting the RAM to be corrupt, meaning im going to sendo the phone back.

    Good luck.

    Hello,

    I can see this thread is pretty old, but hopefully some of you are still monitoring this to see my response.

    I had this sudden shutdown problem for months. I got my Sensation in June 2011 shortly after its SIM Free launch, and the sudden turn off started happening in October. I switched to charging from the mains rather than the USB Socket of my computer which significantly reduced the number of turn offs I experienced but they still happened with sufficient frequency to be a big problem.

    The full story is here:
    Paul's Blog - Technology, Practical reviews and other Ramblings: My HTC Sensation Nightmare

    I had noticed the handset had trouble keeping track of how much battery it had left - for some reason the process monitoring the battery would just stop causing gaps in the battery usage. The screen grab here is typical of the battery usage having a gap which was when a random shut off happened. Also the battery charge remaining varied wildly.The blog post contains some typical screen grabs of the battery level.

    I have found a solution. I had a program installed called TasKiller. I bought it not long after I got my HTC Hero and wanted to shut off apps that had started but I wasn't using. This was back in the Android 1.5 days before Android had its own methods for killing off programs. I installed it on my Sensation and used it semi-regularly with a good Ignore list to stop it killing system tasks and things I wanted to run all the time like the G Mail client. Even when I didn't start it I still had sudden shut off problems so for a long time I didn't consider it the cause. Then I decided to definitely eliminate it as a suspect. I cleared the program cache and settings, then removed it complete and rebooted. That was four weeks ago and I've not had a single sudden shut off in that time, and half that time I've been charging only from the USB socket of my computer which would definitely have caused a problem. Clearly it was starting even when I wasn't starting it.

    If you have TasKiller on your phone try removing it and it may fix the problem for you as it did for me.

    Hope this is helpful

    Hi All,

    Recently my HTC Sensation has been randomly shutting off suddenly. When I turn it back on, the battery meter (which was 90-100%) is now in the red. I restart the phone, and the battery meter then shows about 50% - it's freaking me out. I've had it for about a year.

    I've let the phone run out of juice and then charged it fully but it always does the same thing. I will be in the middle of something and it will just turn off suddenly, with the battery meter then indicating 4-6% charge, and restarting results in random battery meter %.

    I've tried Safe Mode, Factory Reset (which obviously means no 3rd party apps). The phone is not rooted. I have never tampered with it. The phone is not overheating. It has no viruses. My SD card and phone memory are not full.

    The ONLY way I can get it to stay on lately is with AC power (plugged in with charge cable to either Mains or a computer).

    Could it just be my battery has used all it's charges and lost it's capacity? I have ordered a replacement battery as my next step, but can anyone offer any advice please?

    Thanks,
    Jai Skorpio

    Hi Jai,

    Sorry to hear you've had this problem. You're in good company as it looks like plenty of others have also.
    Firstly check out my blog posting for the full story on all the things I've tried - see the post below. It also includes battery usage screen shots which you will likely feel are familiar to you (gaps with the battery level going all over the place). I have more details to add to the blog post but I've not got around to that yet, unfortunately.

    Secondly - if you have an app called TasKiller installed remove it immediately. Go into Apps, clear all app data then uninstall the app completely. I found this resolved the worst of my problems. It seems that TasKiller kills off system processes that monitor battery usage which, for me, caused many of the turn offs.

    Thirdly there may be a mechanical problem with your handset. I started getting turn off problems very frequently about a month ago shortly after the OTA update in early July to 3.33.401.6 from 3.32.401.5 (the original ICS 4.0.3 update). I slipped a business card, cut in half, between the battery and the unibody back. This immediately resolved the terrible repeated turn offs I was getting suggesting there was a mechanical problem with the case such that it would not keep the battery in place. The battery was moving enough to lose contact and turn off the phone.

    I'd never experienced a turn off while it was charging. I did think this was because if the battery monitoring system process was being terminated by TasKiller this would have no bearing because the phone could get enough power from the USB socket. With hindsight, depending on how long the mechanical problem of the loose battery has been there, the micro USB plug would be holding the innards together to the unibody back which may have stopped the battery from disconnecting (and even if it did the USB socket would be delivering enough power that a momentary interruption of the battery had no effect).

    If those steps don't work I'm out of ideas, as those have worked for me, so you're at the mercy of HTC Support I'm very sad to say (unless someone else has a solution).

    Good luck - and let us know how you get on. Bear in mind that these are suggestions only - attempt them at your own risk. They worked for me but YMMV!

    PS - I should say that I'd tried a new battery (provided for free by HTC after I made a fuss) and that didn't make any difference. My phone does heat up (very hot on the car dashboard on a sunny day), my SD card is nearly full with music, the phone memory has space; but it has turned itself off regardless of those things. If you have used your handset intensively since purchase, to the point you have worn it out, then a replacement battery may help, but it didn't help me.

    Hello.
    I just purchased an HTC 10 that shuts down on its own very frequently. I notice a number of posts regarding this issue. They are all old (2011) . But I see no solution. Help
