Phone keeps shutting down & unexpected battery drain

I'm having the same issue, my phone is just 3 days old but it keeps shutting down frequently. When I press the power button it doesn't get turned on, I called customer service who asked me to press power button +volume rocker which turned the phone on. However the main problem still persists -shutdowns frequently. Extremely disappointed with Sony

    My phone keeps shutting down approx every 5-10min for about a minute then it turns back on itself. I have updated the software so thats not the issue, any suggestions?

    Do you have a case on the iPhone or have you damaged it in anyway? If you have a case, try testing without the case.
    Also, try restoring the iPhone and testing it as a new device.
    If that doesn't take care of it, get a Genius to take a look at it or setup service online.

  • My 27" Imac (A1312/EMC2390) keeps shutting down unexpectedly with no warning or "screen of death". I replaced the power supply, reset the SMC, and zapped the PRAM, but the problem continues. Can anyone help me?

    My 27" Imac (A1312/EMC2390) keeps shutting down unexpectedly with no warning or "screen of death". So far I reset the SMC, and zapped the PRAM. I even replaced the power supply but the problem continues. My error and system logs seem unhelpful too. Can anyone help me out?

    You can get a shutdown like that if the computer gets too hot. Make sure the air intakes on the bottom and the exhaust vent on the top are clean and are not blocked by something in your workspace like papers or the back of the computer being too close to part of the furniture. You need a good six inches (15cm) of clearance between the exhaust slot and other objects or surfaces.
    Anti-virus/internet security software, especially the "pay for" kinds, can increase operating temps. So can third-party backup software furnished with many "name-brand" external hard drives.
    Fan motors and/or temperature sensors can fail. If you have the original grey disks that shipped with your iMac, find the on that has Apple Hardware Test (AHT) and run it. If you have a failed heat sensor or fan motor, it will detect it with an error code containing "SNS" if it's a bad sensor or "MOT" if its a bad fan motor.
    AHT instructions here:

    Also see if your iMac 27 falls under theis Apple Repair Extension Program:

  • My iPhone 4S keeps shutting down before battery is low

    Why does my iPhone 4S keep shutting down when it shows I still have 30% battery or more still available?   For example...my last phone started shutting down at 30% and by the time I took it to the store a couple weeks later, it was shutting down at 88% (they saw it for themselves, ran diagnostics, and came up with no issues).  Getting a new phone every 3 weeks is not ideal.  I'm on my 2nd replacement phone in 2 months and it started back up yet again-shut down at 31% a couple days ago.  I charge the phone to 100% and it never fails, it shuts down at a higher percentage each day (it shut down at 35% today).  I have done everything Apple Support has suggested with no luck (including full restore).  Is anyone else having this problem?  Any suggestions?

    Hi,
    I simply use the phone until I have only a little charge left. Once that's reached I'll simply let phone idle completely or drain the rest with lightweight use. We have big difference here as I can actually reach 1% rather than phone dying at 20++ percentages. Previous said, e.g yesterday phone just died after some use with 12% battery left and started again when bringing indoors. I was then able to drain the battery from 12% -> 1% before it eventually died completely. After this I couldn't start the phone anymore instead getting the charge icon constantly, so I just plugged it in at that point. After charging over night I would then consider the battery charge meter calibrated.
    In your case you could test if you can still start the phone at 47%. Even if it's displaying only charge icon you could try to hold the sleep/power button longer and/or do reset with holding home+sleep/power button a few seconds. If it indeed doesn't start it would indicate battery truly is empty. It it does.. then you could try to continue using the phone hopefully hitting lower battery levels and eventually try to fully recharge it in case you'll see the battery charge percentage working any different.
    Below picture shows I can still reach the  "0%" battery level and also pretty good usage times.. so the problem with me really is just that the stupid phone doesn't like cool temperatures (possibly after iOS6 upgrade)

  • MacBook Pro 15" (Mid-2010) keeps shutting down unexpectedly

    For quiet a while now - at least 3-4 months - my MacBook has been shutting down unexpectedly. It mostly happens when it is in sleep mode and I open the lid to use it again. In other case though, it also happened while I was trying to make a phone call or switching to the dashboard. Sometimes it reboots right away, other time I have to press the spacebar. While rebooting it also sometimes crashes on the Apple logo and reboots right after. The Apple logo boot screen also has had the progress bar below it for a while now. I'm on the newest version of Yosemite.
    Oh and sometimes it's fine for a few days or even weeks. Sometimes it only crashes once and not again for days or weeks, other times - like today, it keeps crashing constantly. I also regularly stream movies and shows without crashes. Like I said, it's mostly right after opening the lid.
    Yesterday it got really loud while opening the lid, although it didn't shut down. That made me think there might be a problem with the fans, so I cleaned them - they were pretty dusty. For a second I thought that fixed the issue, because there was no noise anymore. Moments after it rebooted by itself again, though. Unfortantely it crashed during rebooting too, so I don't have a crash report right now. The next time I get one I'll post it right away.
    About 1,5 years ago I replaced my harddrive with an SSD, about 3 years ago I upgraded my RAM.
    Here are some more specs:
    2.66 GHz i7
    8 GB 1067 MHz DDR3
    NVIDIA Gefore GT 330M 512 MB
    While writing this my MacBook crashed again, here's the crash report:

    You have the MacBookPro6,2—the Edsel of Macs. It may have the logic-board defect that was covered by a recall program that has now ended.
    Residents of the EU may be entitled to warranty service for up to six years after purchase.
    Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers do not detect the fault. There is a specific test for this issue that Apple calls "VST" (for "Video Switching Test.") Ask for it. A "Failed" result means that the fault is present.
    You may be quoted a price of about $300 (in the U.S.) for a "depot repair," which involves shipping the unit to a central repair facility and takes about two weeks. For that flat fee, anything found wrong with it should be fixed, not just the logic board.
    Sometimes the replacement part is also defective, so be prepared for that possibility. If you decide to pay for a new logic board, test thoroughly during the 90-day warranty period on the repair. Some owners have reported that they went through as many as three replacement boards before getting one that worked.
    If you don't want to pay for the repair, you may (or may not) be able to work around the problem by disabling automatic graphics switching. To use the discrete graphics processor, you'll need a third-party utility to switch to it manually.
    Often the problems start after an OS upgrade. If the upgrade was recent, and you have backups, then you can revert to a previous OS X version.

  • Nokia Lumia 925 Windows phone keeps shutting down

         I have had a problem for the past 2 months, my Nokia Lumia 925 with Win 8.1 keeps shutting down spontaneously. (I did not have this problem before 8.1)  This is my third phone in the last 2 months (warranty program keeps sending me replacements) and it shut down for the first time this morning. All 3 have developed the same problem, the phone will shut down spontaneously and the only way to start it up again is a soft reset (Volume down + Power for 15 seconds). I have had a total of 10-15 shutdowns between the 3 phones and this is a conservative estimate.
         I am thinking that this has to be a setting or an app that I use (and few others do) that is causing the shutdown since I have only seen a few other similar issues in the forums. Here are some of the basic facts about my situation and some of the actions I have taken:
                  - I have wiped the phones repeatedly (3 phones wiped a total of 3 or 4 times not including the initial setup of the replacement phones, which is getting really old--really fast).
                   - I have tried turning off NFC, but that obviously  wasn't the issue because NFC was off this morning when it shut off.
                    - I have tried trimming the screen protector/screen guard I installed as suggested in one of the other forums even though that seemed ridiculous (I think that was a different model phone too, but I gave it a shot)
    I have not noticed any common occurrence such as
                               --when a certain app is running
                               --when it is on/off charger,
                               -- When the battery is full or low (it was 24% this morning).
                   -I have 2 chargers, 3 if you include the car charger that I have never had to use due to great battery life. 
                   - I have called tech support several times, all AT&T can tell me is that this is not a known issue and I should wipe it again. Nokia says the same and that I should send it back to them for repairs. That seems fruitless to me because I have had 3 different phones, what are they going to repair that a new phone won't fix?
           It takes me 3 hours to reinstall and set up my apps, I am getting very frustrated. I really love the way this phone functions, the software is good, the screen is brilliant and very sensitive, the camera is great (although a bit slow), and the size and feel are perfect for me...I hope that someone here on the forums can help.
    Thanks for your help in advance...

    Hello, mariaadamsky.
    We appreciate you reaching out to our community regarding your concern. You are using a Lumia 925 as well, correct? Did something happen to your phone that possibly caused such behavior? Did you try doing fixes on it? 
    Latest software released for Lumia phones is the Lumia Cyan. To confirm that you have it installed on your phone, go to Settings> extras+info. You can also try going to Settings> phone update> check for updates to check if there's an available update. Are your system apps also updated? While connected to WiFi, go to Store> ...> downloads to check for pending updates. Let's hope that the phone will not shut down while doing this process.
    By the way, we can try other fixes that could help us identify the real cause of the issue. In case you wish to have it repaired in a Nokia Care Point, warranty claim may vary per region and Nokia does not have an international warranty. Also, creating a backup is a must to avoid data loss. Where did you buy the phone and where are you located right now? To know about the manufacturer's limited warranty, go here: http://nds1.nokia.com/files/support/global/phones/guides/Nokia_Manufacturers_Limited_Warranty_with_W.... 
    We look forward to your reply.

  • No sleep but shut down when battery drained

    Hi there,
    just bought a new battery for my MacBook - what happens now is that when I get the battery drained alert (10 min) my Mac quits just about 2 minutes thereafter. Unfortunately it doesn't go to sleep so I have to reboot it after connecting it to power...
    Any thoughts? Thanks!

    macbig, you haven't read much about recent Apple notebooks, have you? All portables since the first white MacBook has had a 'Safe Sleep' mode, which is supposed to activate automatically when battery power drops below a certain level. Active memory is saved to disk, and the computer shuts down all power draining activities. It is then essentially completely off. The difference between this and a standard shut down is that when the power button is next pressed (with a power supply connected), the system resumes after a short wait, with everything still open, just as it was left. This is very similar to a Windows PC's hibernation mode.
    What the original poster here is describing is the problem I am having which brought me here. The safe sleep mode fails to activate, whether the system is active or sleeping. It instead just shuts down hard, as an older model would. In my case, this behavior has been intermittent since my original purchase a year ago. I have calibrated my battery, reset the power management unit, and all the other recommended fixes. My battery is in excellent condition, and in my case, this shutdown doesn't occur until the indicated level is actually at 0%. Nevertheless, it is a feature which is supposed to work, but doesn't. I'm hoping someone else here has experienced this and found a cure.

  • IPhone 5 keeps shutting down when battery is stating good battery strength.

    My iPhone 5 has been regularly shutting down when the battery percentage is showing random charge. Sometimes it shuts down at 20% and the highest has turned off at is 73%. It then says battery is empty and needs recharging, but when phone turns on again it says the battery percentage that it turned off at. Today, the phone was charging for 6 hours and it still said the battery was empty. It finally turned on after another 6 hours but battery said 26%.   Is this just a need for a new battery or something more seriously wrong with phone?

    I'd just like to say that ahs70's post on Dec 1, 2013 at 1:17am on Pg. 9 worked for me as well: https://discussions.apple.com/thread/5338609?start=120&tstart=0
    If your iPhone's battery is acting up you need to determine if it's a software issue or a hardware/battery issue.  To do that, after syncing your iPhone, erase/hard reset all data and settings from your iPhone to what it was from the factory as new.  This can be found in Settings/General/Reset/Erase All Content and Settings.  Then test it out for a day or two.  If it's still acting up then it's likely a hardware issue and you will need to get your battery replaced.  If your warranty is done than check out this link to get a battery kit to replace your iPhone battery yourself:  http://www.ifixit.com/Store/iPhone/iPhone-5-Replacement-Battery/IF118-001#produc tDescription
    If your iPhone is now working properly after hard resetting it than it's most likely a software issue.  This battery issue only started after upgrading to the new iOs7, so it is obviously related to the update not properly installing itself.  What has worked for me and many others is to manually update to iOS 7.0.4 using the full downloaded version of the update which is about 1.32 Gigs. 
    But first you need to find out what model of iPhone you have, click here to determine if it's GSM or CDMA: http://support.apple.com/kb/HT3939?viewlocale=en_US&locale=en_US
    Then go here and scroll down to download the iOS 7.0.4 complete update for your device:  http://www.downloadios7.org/download-ios-7-0-4-ipsw-file.html
    Then scroll up on the download page and follow the instructions of updating your iPhone manually following the instructions below:  "IPSW with iTunes"
    And your done.
    Problem solved.
    I only posted this because it was a very frustrating problem that no one really seemed to figure out a solution for.
    I hope this helps.

  • IPhone Keeps Shutting Down Unexpectedly

    Since I have downloaded iOS 7 on my iPhone 4, every time I use my phone, it locks up and then completely shuts down & restarts. Is there some kind of bug associated with this upgrade or is it something else? It never acted like this when I had iOS 6.

    Depending on the age and use of the phone, it might be time to get the battery replaced.
    Get your phone checked by visiting an Authorized Apple Service Provider or Apple Store next to your place.
    You can also contact Apple Support and talk to them. They can check the battery online.
    You can also visit this page to do that: iPhone - Contact Support - Apple Support
    Click on Apple Support, then on ->Battery, Power &Charging ->Battery questions and troubleshooting, and follow the instructions.

  • Shutting down unexpectedly, battery disconnecting

    I got back to my apartment from a break and after starting up my macbook the battery wouldn't charge.
    It had over 900 cycles so no big deal I bought a replacement. I got the replacement in today, installed it, and let it charge for a few hours. Now when not plugged into the power adapter my computer is still shutting down. While plugged in it seems to go back and forth between recognizing the battery, saying its being charged, and then saying its not charging. Anyone have any idea what the problem could be?

    Also, even when it says that the battery is charging it isn't actually charging the battery.

  • HELP... DM keeps shutting down unexpected

    Thanks all,

    Is it possible your Mac is overheating? Download and check iStat Pro (it's a widget):
    http://www.apple.com/downloads/dashboard/status/istatpro.html
    Check the CPU temp and the fan speed.
    If you have the 3-year AppleCare, you should probably also call and open a case number with them.

  • Why does phone keep shutting down with full battery?

    I've tried rebooting and clearing cache like a lot of people have suggested...
    Is there anything else I can try?

        Hi deesbees,
    I appreciate you taking the steps to reboot and clear cache on the device. If these steps have not resolved the trouble the next step is to complete a hard reset. These steps can be found on http://bit.ly/oV4Meh. Please keep us posted to the experience after the reset.

  • My macbook air keeps shutting down unexpectedly, any thoughts? It seems to be while streaming movies etc and i think it's when the power cable is plugged in, not while on battery

    It's only 3 months old, I think it's mostly while streaming movies from the net whilst the power supply is plugged in? I have seen a couple of other similar posts. Any thoughts or advice greatly appreciated.

    Try a SMC reset.
