Have you sometimes meet the problem: your cell phone turns off automatically and you totally have no idea why it happens? Maybe the following text can give you the answers.
1. Your set your phones to be shut off sometime before, but you foeget what you shave done. What a bad memory you have, guy!
2. The power of your cell phone battery runs out so that it is automatically power off. You’s better charge it immediately at that moment. Please remember to charge your phone when its power runs low.
3. There is something wrong with the softwares of your phone. Maybe the software newly installed is incompatible with the system of cell phone, so that your phone complains to you in this way.
4. Your cell phone is infected with a virus which can shut down your phone. In this situation, you have to search for a doctor for your phone.
5. There is a hardware failure of your cell phone. The broken power amplifier may lead to auto shutdown. The overheat CPU is another common reason.
6. The components of your cell phone get loose. For example, when the cell phone battery is not connected with the phone closely, the phone can not get power from the battery so that it is turned off.
7. There are some problems with your cell phone battery. If the protective circuit of the battery is too sensitive, the cell phone will be shut off when the current becomes larger. The battery which is too old to work can not offer power. That the battery sheetmetal is dusty or rusty, which leads to poor contact, can also result in auto shutdown.
this is helpful. thanks.
And if I may supplement one point, it's that when you find your phone automatically shuts down and the battery or the back of your phone feels really hot. Don't try to turn your phone on. Pull off the case and get off the battery until it's back into normal temperature. If it happens a lot, better go to an expert to check it out.
I've read news that some badly designed batteries exploded out of high temperature and thus hurt people.
Ok.
Let Me Guess
Just A Thread To Say Why Its Powered Off??

as i said in the title when i use wifi i get a about 2-5 mins of use out of it, but then it will cause the pda to shut down, even when i have full battery and its plugged in, and it wont completely turn back on till i plug in a charger, occasionally even this wont help for a while, i also have had some problems with the battery, like sometimes it wont be recognised by the pda so it wont turn on and will show the red light when i try to charge it, could that cause this problem?
Sounds like new battery time.
My last one used to die if I had the backlight on for more than a few mins, it lasted a year (the original battery).
Got a new cheap one from eBay, seems to be going fine with good battery life.
thanks i thought this was the problem so i bought a new battery last week, still hasnt come yet though
Hi
i have the same prob too, but when i plug it into the charger it won't turn off!!!
this is an actual common problem possibly residing to a specific batch load or maybe more. the problem will get worse and in short it's not a battery it's a mainboard problem with a sensor or a part that becomes hypersensative to heat. I think it's part of the same circuit that shuts the device down if the cpu or battery overheats but I can't proove it yet. I've had 2 of these phones so far. 1 3 got t-mobile t swap for an mda vario 2 at the time as the phone wouldn't stay stable for more then a few minutes. same result with 2 like 4 like replacements they sent me. ifinally said enough I want the closest thing tech spec wise to it. the 2nd one was my wifes which she barely used now that shes moved on to a different phone I've started playing a bit with it as it's over 12 months old. and I put it back into the box and up on a shelf as soon as it started doing the rebooting thing like the first one. NO WONDER ORANGE START DISCONTINUING IT AS WELL DID T-MOBILE UK.
UPDATED :
After reading a few of the posts aftr mine, I set out on a mission to determine the more exact reason for this cause. I found the unlike most mobile e.g: sony, lg, nokia etc. this phone would nout power on from the mains adapter without the battery. I figured initially it must have been the manufacture thinking this is not a laptop and the mains adaptr was intendd to charge batteries and then run the device. this also prevents data loss or file system corruption incase your mains charger comes loose from the device while playing. however I found that by putting my finger (when your finger tips are lightly moist and conductive) over the battery terminals on the device it would infact power on and work. now in light of this there are 6 terminals to make conduct with the battery the outter 2 on each extreme end are your + and - . the 2 inner ones are likely then to be battery voltage sensor and battery temprature.
so I said great way to test a theory. I unplugged the mains charger and started downloading files from my pc to the memory card over wireless. this of coarse caused the battery and the device to heat up very quickly. within about 10 minutes it did as expected and shut off. then when pressing the power button could not make it back to the main today screen either it would shut off on the windows mobile splash screen OR it would shut off during the first splash at bootloader.
I then removed the now very warm battery and put my finger on the battery terminals making sure the 2 center pins were touching my finger. voila th device powered on and booted up just fine. I then went back to doing file transfers and it never shut off on me again as lon as I held my finger on the battery terminals. in short I fooled it into thinking the battery was there but but that the temprature was fine. wm6.1 from ranji's 7.1 could tell there was no bettery to charge but the temp sensor was fooled. conclusion: the reason 2 replacement handsets in the past sent to me by t-mobile conitune to fail was not infact an internal problem that was main board related it was the battery incorrectly sending wrong temp info or a faulty battery that was getting to hot and the manufactures own safty device was shutting the device down to cool off the battery. this would be why in the past I would be able to just leave it off and eventallly it would work again. I felt like such a fool but at the same time I felt good that I got 1 traded for a vario and that now all I need to do to fix my mda pro is t get a new battery. I am man enough as you can tell to say wheni was wrong and I was. in light of this new info I would recommend the device to others but if you start getting random shut downs and turn offs during internet over wireless or gprs and the device is wamr ask your provider for a new battery or replace it yourself maybe even with a larger capacity one as it will likely resolve your problem. I know there are other posts i've done about this subject and I HOPE that those that have read them read this update as it applies to all htc universals regardless what branding they fall under.

just a reply to kick this into attention as will be important to a lot of people I bet
TLDR: Skip to TLDR near the end!
Well, this is probably the tipping point that will make me demand a new phone from Magenta, because this is getting out of hand. My phone will periodically stop charging, for seemingly no reason at all. Usually its when it has relatively low power already that it decides it doesn't want to recognize the cable being plugged in.
Usually, I will just pull the battery and drain the remaining power via the power button, put the battery back in and all is well. Lately, it happened that it stopped charging and didn't respond to battery pulls, then got so low that it refused to even boot (flashing empty battery icon). This lasted about a day and after I had went into the T-Mobile store (Which they MADE me drive 30 minutes to the store to be there in person so they could hand me a piece of paper saying they'd mail me a new unit. Bull**** in and of itself.) the phone decides it wants to start charging again. After a few more frustrated battery pulls and doing nothing new with it.
When I get my new phone (no new battery), I put the battery in that one and use it, and all seems fine. This one has worse screen bleed (top left corner was pretty much a spotlight), but I'll take that for a working phone at this point. A few days ago I was just heading out on a 3 hour trip for a short vacation when the phone reboots on me while I'm listening to podcasts. Never had this happen with the other 2 G2X's I've had. Yesterday, the thing decides to stop charging as well, but a battery pull while the device was still on did the trick and it charged again.
Once I got home I figured I'd use the original G2X, as that has everything still on it, and migrating those app settings and data is a pain. Also, if it has worse bleed, reboot problems, and the same battery issue, its worse than what I already have.
(TLDR)
Now to my current problem. The phone, once again, stopped charging and has again discharged to where it wont boot. My questions:
1) Is there a way to recover my battery without just letting it sit and praying it charges again?
2) What is the underlying issue here that could cause this? Bad software? Bad hardware (in the phone itself)? Bad battery?
3) What is the best way about getting a new phone for free (or as close to free as possible), preferably an upgrade like the Sensation 4G? I don't want to deal with my local store, as they have been proven to not know ****, and the first line of defense on the phone isnt much better.
Well i am not an expert here but Just by process of elimination it seems to be the battery. They gave you a new phone and not a new battery and now it is doing the same thing. It has to be the battery so I would go back to the store and tell them that they gave you a **** phone as a replacement and it was the battery that was the problem the whole time. They shold be able to give you a new phone and battery. Tell thewm the screen bleed is terrible and the phone yoyu had was really good except for the battery issue. Maybee someone else can give a second opinion about that battery though. Dont just go on my words I am not a pro. Good luck man.

I get my hands on a Desire S, that refuses to turn on. Now the battery is charging in a another one, there are no problems with the battery. Any suggestions what to try? When the battery will be at 100 %, i try to turn on.
When phone is charging, is there the LED orange/green? You can try the following. Plug in the phone, and while is plugged in take out the battery and try to start it up without the battery (but still plugged). I know that there was something like this written in a topic, when someone adviced to turn the phone on, then take out the battery while it was booting and the phone will still run even if the battery is out. It could be something similar with some laptops that can start regardless of the presence of the battery
Ok i now tryed to turn it on, even with the cable, nothing. Seems there is some hardware damage. Seems i have to buy new mainboard. Anybody got for sale a desire S with damaged screen ?
Just out of no where my phone doesn't power on and the orange led light that comes on when your charging it doesn't come on either. Does anyone know what I should do? I tried that recovery image thing but I don't know if I did it wrong or what?
When I type in
adb reboot
or
adb reboot bootloader
It gives me the following message "adb reboot is not recoginzed as an internal or external command,operable program or batch file."
By the way im doing this on the command center on my computer.
I do not have water damage and have never dropped the phone or anything? could this be a hardware issue?
Hmm ok sounds good I will do that!
I had a similar issue on my old Evo. As it was explained to me, the battery is so dead that the phone doesn't even recognize it's physically there. The solution that worked for me was to "jump start" the battery from another phone. Make sure the other phone's voltage is the same (I had another HTC, so there were no issues). On the battery there are 3-4 contacts, and the sticker identifies the pos and neg. Simply get two wires, lay them between the battery contact and phone contact on the functional phone, and hold them to the corresponding contacts on your battery, essentially wiring your battery in parallel with the other phone. Hold them on to charge for about two minutes, this should put enough charge back into your battery to allow your own phone's sense circuit to recognize and charge it. It worked for me causing no damage to either phone, and the battery didn't even lose any perceivable life.

Well when I brought it to the cell phone repair store he did a check on the battery and said the battery was fully charged and he checked the phone and said that it was accepting a charge or something. Im just not getting power. Unless the guy at the store is an idiot and wanted to make money off me. I don't know.

Happened to me too. Lucky for me a friend had a stock Sensation and I was able to charge my battery on his. When I popped in his battery on my phone it turned on fine, but this was sometime ago.
Sent from my TripNiCE Pyramid using xda premium
Hello there!
I've been using my Sensation XE for about 1 and a half year now without too much problems, but I feel like my battery is dying.
On the stock rom the phone would randomly turn off (like pulling the battery out) and when rebooting most of the times it would keep turning off unless a charger was attached. Looking at the battery status, it reported the battery dropping from whatever it was at (sometimes as high as 90% charge) to 0%. Going back up to the old amount (or a bit lower, depending on the amount of reboots I had to do to get it to stay on) after it booted.
This can happen 5 minutes after it's been fully charged so it's not an empty battery somehow reporting 90% charge.
Since then I have rooted my phone and put a custom rom on it (the Cyanogenmod by albinoman887 found here)
The issue seems to happen less, but it still happens. Random drops in the charge causing the phone to turn off.
I have tried putting something behind the battery to improve contact, it didn't help.
I have seen a lot of people praise the Anker batteries on these forums, so I wonder if it's worth getting one.
Will a new battery fix my resetting problems?
And since appearantly the Anker batteries are less then the 1900 mAh promised, will this give my any improvement over battery life over my stock battery?
I attached a screenshot of the battery screen after one of these shutdowns. On the right side you can see a drop to 0% battery and it going right back up to above 30% charge (not near the previous amount, but 30% shouldn't cause the phone to turn off)
Thanks already for the help.
*bump*
You told that putting something behind the battery didn't help, but just to be sure, did you try hiting the phone and seeing if it causes a turn off/reboot? (hitting gently, just to make battery move, and not damaging the device itseld. Did it to my brother's desire S on my hand). if it's from physical movement, try the paper trick again, as it might have not been enough to keep the battery in place.
I don't know if getting an Anker will fix your problem, but if nothing else works, it's worth a shot.

Hitting it like you described won't make the phone turn off.
I even tried manually forcing the battery away from the contacts without the phone turning off.

I did some reading on the subject, and people seem to have the same issues even after battery replacement. Some people reported that locking their device to 3G only (WCDMA Only) solved the problem, and that their phones were crashing when in 2G for more than 10 seconds. I think it's worth a try (although firmware has been updated since what I found was written, it's worth a try).
To change your connection settings: On the dialer app type *#*#4636#*#* and when the Info screen shows up, enter phone information and on connection type choose WCDMA only.
Will search for more answers, but in my opinion, before buying a new battery you should try to fix it on the software side.
By the way, I once caused my phone such behaviour (but for me it was just once) by forgetting it for 20 minutes in a -30°C freezer, which killed my battery for a few minutes. Did you see any strange behaviour of the phone (besides shutting down) around the times it happens? It might be heating, having a certain app or as I said above, connecting to GSM instead of WCDMA.

I did the connection thing, but since the turning off is kind of random I cannot tell yet if it works.
As for weird behavior, I doubt it's an app since it can be hard turning it back on at times (crash on the sim pin menu or even before). This would mean that the app only boots sometimes.
And for temperature, the phone doesn't feel that hot. I've had times where I was using the phone intensively (games) and the phone would be quite hot afterwards, without turning off.
And I didn't ever leave it in a freezer either

No, the freezer was just an exmaple of my stupidity at times
But I think this could be related to radio, as some people reported locking their device to 3G-only fixed the issue for them (of course, you might not have reception everywhere). Try doing this via the testing menu - dial *#*#4636#*#* and in "Phone information" select "WCDMA Only" in the drop down menu.
My phone didn't randomly turn off since I changed the radio setting so it seems that the radio setting solution worked. Thanks a lot astar26!
