[Q] 4.3 Low Battery Reboot Cycle - Sony Xperia T, TL, TX, V

Hey guys, I've got a bit of a problem after the latest 4.3 update. My phone battery went to 7% and then suddenly to 0%, upon which it turned off. Now whenever I try to turn it on the red light flashes and whenever I try to turn it on whilst charging (because I don't think it charges if I just leave it plugged in), it just enters a reboot cycle, whereby it goes to the lock screen, shows the "Shutting Down" window and reboots. I have no clue how to fix this.
I don't really care about the phone at this point, but I do have some photos I want to keep from there...
Any ideas? The software hasn't been pampered with.

same here
hey, feeling with you.
I recently updated my Xperia T to 4.3.
While in 4.1.2 the "low battery" behavior was quite weird, as my T did not charge (no red LED), I was able to get it back to life by pressing and holding the power button for quite some time, lets say 5 min. or so, as it was loading then. This was independent from whether it was exhausted (blinking red LED) or "simply of"(not blinking but not charging anyways).
Through this whole power pressing procedure (I just wrapped the cord around the phone several times) the LED was red and the phone was charging, but it did not turn on. After the 5 min. I freed the T an hit the power button again. Now it was booting as expected and did not immediately go off again.
On 4.3 unfortunately this does not work anymore . The phone just tries to boot and enters the reboot cycle as you described (with the difference that it does shut down instead of reboot).
Now first I would like to know, if your T behaved like mine under 4.1.2 (guessing that was your last Version too). From what I've read I assume that wasn't really normal behavior. I think there must be something wrong with the hw, as my 4.1.2 was neither unlocked nor modified in any other way.
Second I would advise you boot into recovery and select boot into bootloader* (if you have installed one) or connect your T to your PC and boot into flashmode (power+vol.down I guess) as it might charges in there. The recovery worked for me, flashmode should work, but I never tried.
Finally I guess chances are good, that your device works totally normal if it gets charged again (just don't let it run out of energy again )
btw. does the Xperia T normally charge while it's powered off? Anyone has send his phone back on warranty because of charging problems?
good luck to you,
wk
*I am using this 4.3 rom (http://forum.xda-developers.com/showthread.php?t=2647459) atm, as I have root there. But the recovery is really buggy right now so it just restarts all the time. I'm not quite sure where the "boot into bootloader" option gets you ( never heard, that you could boot into bootloader on an xperia device) but the LED shines blue and the T charges and that's important right?

Yeah, my T would sometimes do that when the battery completely drained. I'd have to hold the button for a few minutes while the red light was on until it booted and started charging autonomously.
Now that doesn't work. It doesn't charge when it's off and when I connect it to the charger and turn it on, it restarts. Eventually though the battery drains completely and the old trick works again, but even when it manages to boot to the lock screen, it shows 0% battery again and restarts.
I've tried turning it on while holding the power+down button and charging. The green light came on and disappeared but it started rebooting again. Same with connecting it to my PC.

Can you remove the battery?
Same thing happens to mine,and i just remove battery,plug it without battery,it starts,then put the battery back on.
And it charges fine.

But the battery is inbuilt, no? Would I have to disassemble it?

So I think you are facing the same issue as mine... the phone has no time to charge. So what I did was flash an OmniRom with only the SystemUI apk and launcher apk. The intention was to make the boot time shorter so that the battery will not go down by the time it boots. But it ended up causing a bootloop: it was constantly stuck in the bootanimation. And it does charge during the bootanimation. So I let it be like that for about 30 minutes, rebooted to recovery and flashed the stock rom. And all my data was safe. This is more like a fluke so try it and maybe it would work.
If you can disassemble it, then yes, you can do the battery thing. There is just one screw under the SIM flap. I didn't do it because my screw driver kit was borrowed.

The battery trick worked! Now it discharges really fast though.
5% in less than 5 minutes...

My D3 died! :(

:crying:
Opened bike race when the screen froze while opening the game (dark screen).
Pulled the battery but when I boot the screen goes on after 3 secs, stays on for 2 secs then goes into dim mode (i can see it's still on).
However my phone doesn't boot since I don't get any whatsapp messages. Normally it should boot to SIM screen but other apps should run.
X+power or M+power doesn't change much.
I'm guessing mobo/cpu fail.... any ideas?
:crying:
edit: It turns on when I put in the charger without battery! Dead battery?
If you put the battery flat on a table does in spin well. Batteries bulge when they are done. The better the spin the worse it is. It's odd the behaviour that can happen with a end of life battery

Well now I'm not so sure what it is.
When I put the cable in without battery the M logo appeared and then the charge screen with a ? in the battery (because there was none)
Then I put the battery in and it started charging.
After a while I tried to turn it on but same problem - just a black screen when power it, no logo whatsoever.
Now I can't get it to work without battery either...
edit: I don't think it can be the battery, because the screen stays on (it has power apparently) and it doens't work with cable connected either
But I also don't see it being the screen as it never vibrates like it does when you boot it.
How did it just show the charge screen before and now it doesn't??
I made a vid of what happens when I power it:

The Droid 3 and Bionic are similar phones, and it turns out that the Bionic will not boot up without a battery - it will hang at the Moto logo even if plugged in. See this thread at androidforums.com: http://androidforums.com/motorola-d...via-adb-unable-boot-up-phone.html#post5463741
So, it may be that you just need a good battery pack in order to get to Recovery/Bootloader/Fastboot etc. if the phone will not start or start to Safestrap.

The worst part is using my Samsung Jet "Smarter than a smartphone". Which isn't even close to a smartphone because it doesn't have any of the OSes = no apps
In my XT860 in its power when it reaches the lockscreen, restarts or shuts.
When I put it to charge my battery shows 0% and charging. When I go to Safestrap-after several attempts-, battery shows 99% or sometimes 80%.
I think the cpu wants to leave the world of technology :crying:

I tried the stock cable that came with my phone (USB) but nothing happens. Screen doesn't even go on.
The light next to the microUSB does go on.
But my phone has never booted with USB (0.5A). When my battery was 0% I always needed a socket charger because it wouldn't go on and charge with USB
When I then insert battery and try again with stock cable same happens as in the video

Ah I see. Well I'm not in the US so getting one would be a PITA
I'm gonna try my spare battery (original battery) tomorrow. It that doesn't work it must be hardware related because I haven't flashed or done anything to it so it's not softbricked or something.
edit: it team blackhat do send to europe? How would this be different from trying another (working) battery?
Try cutting a USB cable open, hook the red wire to the + of the battery and - to the black and let it charge that way. Also, do you have any MicroUSB charger? I have one for a BB Bold I used to have that delivers I think 1.25A and it could charge my phone from dead (obviously not now with the flex cable having a rip in it).

The little light next to the USB port is the 'It's still alive" light that Moto put in when the battery is completely dead. It's to let you know that the phone *is* charging, just not high enough to boot the phone (i.e. when you let the battery completely die).
WHY they did not make it a standard charging light (like the D1 and D2) I don't know, but that's the only time it comes on. A quick flicker on USB plugin, or when the battery is dead. The light goes out when it gets enough power to boot up.

Well, it's not charging because there's no battery , the light it still on
I really dont see how its the battery because when I put it in without cable the screen turns on and stays on for as long as I keep the battery in. So it HAS power. Today I'm getting my spare battery and we'll see I guess..... don't have my hopes up
My daughters D3 was doing the same thing,me being not ready to dig into a phone yet ,took to a local repair shop, they checked it out and found it had a bad LCD,should get back Friday, sorry for the bad news,just thought you would like some insight.

Thanks. But should it turn on when the LCD is bad? It doesn't even boot else It would vibrate once.
Can anyone confirm that the phone should boot when I remove the LCD alltogether? Else it might be a bad LCD or loose connector

[Q] HTC Vivid won't charge or turn on

As the title says, my HTC Vivid won't turn on, charge or anything. The orange light that says it's charging doesn't turn on, buttons don't vibrate or anything. It shouldn't be bricked because I haven't done anything to brick it. I was using Xbox Smartglass on it, I locked the phone and went back to my game, about 15 minutes later I tried to unlock it and it did nothing. The battery shouldn't have been dead because I charged it the night before. Any suggestions or help please?

LOL The reason I got a Vivid is because he gave it to me. Sadly, I was hoping there would be a technical solution instead of trying a new battery. I've got one ordered though. :/
Some have bad batteries.
Mine started doing the same thing. For a while I thought the battery life on Vivid was horrible compared to the Aria I had at the time. Then it progressed and one day finally quit completely and would not take a charge from any charger I had. So, being a techhead I decided to probe the battery with a multimeter and it showed very little voltage, so low I guess the charger wouldn't even recognize or try to charge it.
So what I did was take a battery charger I had for a walkie talkie radio and touched the leads to the battery for 3-5 seconds or so, put battery back in phone and it would then charge. I did this a few times until I could get to ATT store and the guy ordered a new one through warranty. Haven't had a problem with the Vivid since.
Same Problem
Last night I pulled my battery at 21% after shutting the phone off to clear the memory. I put the battery back in and put it on the charger, I tried to turn the phone on and nothing. It is not showing that it is charging. I have four batteries for this phone and none of them will turn on the phone. I am at a loss here. The phone was working fine until i shut it down and removed the battery. Any ideas on what is causing this or any way to force it to turn on.

That sounds like a royal pain.
Could it be the changer or its USB cable? Work some contact cleaner into the power button?
I'm having this same issue. I'm not sure if it's the battery, since the phone boots to bootloader just fine. But the battery won't charge when the phone is off (red light comes on for a second, then quits) and I can't get past the HTC screen booting to ROM or recovery. Where is a good place to buy a battery?
Even if the power button was bad the phone should still charge a battery. I have a charger that will charge the batteries without the phone so I know the batteries are charged. I have several different chargers and none of them will show the phone charging. I even tried connecting it to my computer. The phone is dead, I guess I am going to have to crack it open and see if anything has come loose inside. I really like this phone and am going to hate loosing it. I paid a lot for this phone. That shinny penny I paid to get this phone was my favorite.
Have you tried plugging the phone USB into a desktop and using that to try rebooting the phone into bootloader or recovery?
Hasoon2000's Vivid All-In-One Toolkit in the dev section can do that pretty simply. i used an earlier version of that to unlock the phone a year and a half ago.
i don't remember if the phone has to have debugging turned on for the desktop to feed it commands.
Even if this works i dunno whatall it'll prove.
i like this phone too a lot, and am sorry yours seem to be having hardware problems.

The phone does not turn on at all so getting to the bootloader is impossible. It does nothing. Does not even charge a battery. .

That's the definition of a bricked phone, was what i meant. No screen, no led, no button function, no sign of life, and from no explicable cause.
Android phones don't have real on-off switches that directly disconnects the phone from power. Its failure to manifest signs of life doesn't absolutely indicate irreversible hardware failure. There's a bit of a chance it's firmware.
Aside from the power button, Android phones can be controlled thru the USB port.
I took your advise and plugged the phone into the computer and left it over night. This morning I rebooted the computer and the phone screen lit up. I got all excited and tried to use adb to reboot into bootloader, Of course the phone was not found. I took the phone off the cord and the screen shut off. I pushed the power button and the screen lit up. Let go of the power button and the screen goes off. I tried another usb cord and now the screen no longer lites up. Maybe there is hope for this phone.
If the screen lights up like that... there is power to it...
Sounds like you have dirt in your power button... or the button isn't making contact...
Time to disassemble and check the power button...

Yeah, that part where the phone was seen by the desktop, and then not, can have something to do with the Windows drivers. Most of the folks on these forums know what's with this stuff better than me; i usually have to tell windows to stop the hardware, disconnect and reconnect the phone USB and start the connection up again, every time before i do one set of commands, like put the phone into bootloader and download a kernel image into it.
There's a Vivid unbricking project over in the dev subforum, you must've seen that. Whether or not you get your phone working again, i hope it'll be a productive journey for you.
i was perfectly happy just messing with apps until i bricked my tablet; that got me into all this device unlocking and rom burning and fun stuff. It's too bad the Vivid isn't simpler to hack.
my phone cant boot to desktop after i flash the kanel
my phone cant boot to desktop after i flash the kanel please can you help me
9 times out of 10, if the phone will not turn on at all it is the battery. For some reason, the Vivid will occasionally stop seeing the battery. I have fixed this on mine when that happened by using an external charger. That worked because my battery was actually OK, the Vivid just wouldn't charge it or even see it. Once it was charged it was fine. If your battery really is dead (sounds like it might be the case), get a new battery. There is a 2000 mHr battery on Amazon that is not too much worse than the original (when new).
I had the same issue once, it turns out that I fixed it using a external charger

[Q] Battery's dead (?), phone won't charge anymore

Hi,
So... After flashing 4.2.2 everything was going great since this Monday... i spotted that my battery level was changing like a freak (on Excelsus 4.2) and whenever i wanted to plug in my charger to phone it didn't show the charging icon, but on phone turned off it showed but level wasn't rising... So i wanted to flash system backup, but then i got softbrick... I couldn't even get to recovery anymore, so next day i flashed .253 but it didn't change anything. I tried also to flash .423 again but it also nothing changed. And today, after recording some video, phone went dead, so i thought that i'll be able to charge it, but no. Whenever i want to turn on phone, it vibrates and nothing more happens, when i plug it to the charger, the red led light lights, sony logo appears, phone turns off and it loops... Any solutions? I can barely flash anything thru flashtool, but it also does nothing. Will I be able to send it as warranty repair or it may be voided? (i unlocked bootloader, but now it's locked)
I attach a screenie from yesterday, where you can see that battery level went insane and in addition it didn't want to go higher than 58-60%
Regards and thanks in advance,
Bairei

[Q] HTC One Charges but Won't Turn On

Hello guys,
A while ago, I was just doing stuff I normally do with my phone. I flashed a ROM and it rebooted normally. I then flashed a MOD using TWRP recovery. As usual, every MOD that uses Aroma Installer has a "Reboot device after install" option so I chose that and then **** happened.
Out of nowhere my One suddenly shuts off (The install was done so...)
I have tried the sensor under bright light trick and my phone does vibrate once but nothing actually happens. Just a black screen and stuff.
Sometimes it does go into this screen where it shows a battery icon with thunder bolt in the middle (Yes I know that is the charging screen. But, I also believe that it acts like a progress bar and it does not do THAT.)
Then again, it dies and it doesn't have the charging LED nor would it turn on.
Help is appreciated. I know basic and complicated android stuff but I can't do any of that if my phone is dead
Edit: When I press the power button for a few seconds, it vibrates but nothing happens. The screen is still off and the charging LED is not turning on as well.
Edit: Okay, when I do get it to charge, it shows that charging screen and when I unplug it, it freezes with the charge light on. The phone is also heating up so that does mean it's charging

TAM

No. But I was able to drain the battery and once I plug it in using the original HTC wall charger (which is the one that I always use to charge it.) it charged but the charging LED is blinking (mut have drained it self good overnight) am I making progress or did I make it worse?

It's difficult to say at this point, Personally I would just leave it charge over night. Then try and power it on with Volume Down+Power while still connected to the charger. And it definatly doesn't show up in device manager, not even as Unknown Device or QHUSB_DLOAD? I find that a little odd.
But there are signs of life so I think a good charge may do the trick.

Yes. I did plug it into my laptop's usb ports last night when it still had charge (usb 3.0 if that helps) but it was neither recognized nor visible in the device manager. I hope! I am now charging my phone as we speak. I hope it's not dead too
Okay so...I installed HTC Sync and still nothing. It was not recognized and it's still not booting
Try Windows 7 USB 2.0
just htc Drivers
Try to go to Boot loader and flash firmware
if it show battery with charging sign it means Soft Brick or battery problem
if it showed nothing like no charging light or nothing on screen then its Hard Brick

Then it is probably a soft brick or a battery problem. Because when I got home I immidiately pluged it into the wall charger for it to charge and it charged showing the charging screen with a blinking LED. One more thing, if I press the power button for a few seconds it vibrates and then nothing happens. I am planning to leave it charging over night. Is that a good idea?

Because when I got home I immidiately pluged it into the wall charger for it to charge and it charged showing the charging screen with a blinking LED. One more thing, if I press the power button for a few seconds it vibrates and then nothing happens. I am planning to leave it charging over night. Is that a good idea?

can I ask what your flashed before it did this ?
also crazy question, but have you tried holding down the power button till the lights on the bottom flash approx. 12-15 times ? this resets the device, Ive had to do this after many flashes of various things.

I was flashing a MOD then after the installation finished, it asked if I wanted to "reboot now" so I tapped yes then the phone died and it won't start anymore. Yeah but how long should I hold the button? Just to clarify, my phone only vibrates if I hold the power button for a long time. It just keeps vibrating and vibrating

until the lights stop flashing, usually about 12 or 15 times cant quite remember exactly how many times they flash but its quite a few.
I know you said you tried the bright light trick, but you should also try this trick whilst holding down the power button.

Umm...but the buttons don't light up when I press the power button for a long time.
It does this but when I unplug it, it freezes like that with the LED on.
Edit: When I plug it in the computer it doesn't show up (I think that's good because it's a sign telling me that maybe the phone just needs a long ass charge). Now I will be leaving my phone to charge over night and hope that it will boot up in the morning. The phone becomes hot too while it's charging.
Note: I also do not have access to RECOVERY, BOOTLOADER and FASTBOOT.

if your phone is in warranty you should go to service centre
This situation is quite confusing
as not accessing bootloader is not good sign

Oh no...well I will try to search for my old laptop that has USB 2.0 ports and see of that recognizes my phone. I also do not have warranty anymore though so that is not going to help me

Okay so I plugged my phone into a laptop with USB 2.0 ports and it showed up in device manager as an "Unknown device". Not sure if it was caused by the phone showing the battery charging screen but anyway that happened. Is that a sign of life? What should I do about it?

Well as you have tried everything else, and now seeing some signs of life, you could give this a try, no harm in trying, it will either work or it wont.

What version of ubuntu do you recommend I use? I will be installing it on my flash drive so...

Seriously need help with P8 Lite

I suppose my phone is soft bricked. It doesn't get past the Huawei boot screen. I am still sort of able to enter bootloader and recovery, but I have a problem charging the phone also (which happened after I left in in fastboot mode connected to my PC for a little too long), which means no power to keep it on long for enough to flash rom via fastboot, and trying to do it via 3 key combo with UPDATE.APP on the memory card just says the image is incompatible. The thing with the battery is, when I plug it in it shows that red circle with lightning bolt in the middle like when it's charging, but it immediately changed to green (as if it's fully charged I assume) and the red led flickers. As I understand it, the red light flicking means a battery fault. I know when the red light stays on continuously it means the phone is charging, but that doesn't happen. It just blinks. I can disconnect the battery and retry and it always just keeps blinking, and turning it on means it'll die within 30 seconds. So I can't unbrick my phone if the battery won't charge and furthermore Best of ll is this is I installed a new battery 2 weeks ago and had no problem new battery. I even replaces it AGAIN when I thought the battery was faulty. So perhaps you guys know of some software, hardware, or unconventional trick to get it to charge. I'm very desperate for help! Thanks all for reading!
Just keep it plugged in overnight.

Your battery is drained.. That's the thing.. Charge it, the LED will blink red few times amd as you mentioned, red circle will turn green.. it doesn't mean that the battery is full charged, but instead, it means that the battery is charging... Let the battery charge for few minutes (possibly an hour or so). Do note whether the phone reboots or not.. if not.. its ok..
After charging your device, switch it off (if your device is turned on). Connect it to your PC and just press & hold the vol- key... It should go into fastboot mode... If it goes, then just flash the boot image of your current build..
I too faced similar problem few days back amd resolved it by doing this.. (I was on b596 when I faced this problem, I flashed b596 boot.img)

I thought the green circle and red flashing led meant doomsday for my device. I left it overnight at some point and it even got really hot. Strangest thing is, the screen doesn't turn off when it shows the red circle and blinking red led. And having left it overnight like that connected to the charger made the phone very hot and it didn't charge at all.

I did in fact flash some things, but even after that charging worked just fine! (that was before this charging problem) Just now it doesn't boot. (but I was certain flashboot would rescue me. I know I flashed something I shouldn't have, which is why I'm eager to get back into fastboot, but can't without any power and the PC USB to phone connection doesn't provide enough power for it to stay on.
This oddness started randomly while my phone was connected to my PC in fastboot mode (thankfully before trying to flash anything or running any commands)
I very sincerely hope someone has answers for me. I'm desperate as this was a gift and I just had to tinker. to try a better rom :crying:
But luckily I know this forum has the best experts around!
Is the problem the same as the people in this thread
Open the cell phone and disconnect the battery and reconnect it.
I had the same problem and solved it this way.

Either you open your back case and remove your battery..
Or connect your device to the PC but just by holding your vol- key, that will boot you in fastboot mode.. no matter how little charge you have, it should work

Hey there, thanks for your reply. I have in fact disconnected and reconnected the battery countless times without any effect. I also connected it to PC, disconnected battery, reconnected battery while holding VOL- and it didn't boot into fastboot, just the green circle. Just switching it off with the power button makes it switch on again immediately and holding VOL-still doesn't boot into fastboot mode. I actually once got it to boot into fastboot mode, I can't remember how, but it lasted about a minute then it died from low power even while connected to a US 3.0 port with extra power. y the way, one oddity is that when holding VOL+ is actually goes into recovery mode, but I reflashed stock recovery to try and to flash the UPDATE.APP automatic upgrade, but it didn't work and so it's pretty useless.
Thanks for all the suggestions, you guys are awesome! Really hoping you guys can help me out in the end though!

Has it charged since then? When you plug in your cable, does it charge, or does it turn on?
I tried charging with powerbank (at that time, I was out on a bus), it got superhot (the only hot thing I got in my life) and it was turning on automatically... I let it charge for 30 minutes, and then I hold the Power button to shut it down (but it didn't work, I guess).. then I connected it to my laptop just holding the volume- button, it did boot to fastboot..
I am out of suggestions, will post you again if anything else comes to my mind...
Hang in there buddy..

Nope, it's not charging. I've used multiple chargers and even different PC's USB connections, but all that comes up onscreen is the round green logo with the battery, and sometimes a red one instead of green.
And of course the constant blinking led, it never goes away. and also the screen doesn't go off like it does when it's charging. I swear the moment it turns solid red, if that ever happens, I shall rejoice.
Nevertheless, I have utmost respect for this site and faith in its member! :good::laugh: I just KNOW someone will help me resolve this. I can enter recovery (stock) but it doesn't charge there not does the silly stock recovery have a option to turn off. And even sometimes when it seems completely drained, it seems like it starts charging after about 2 minutes after I plugged it but it turns on the screen, shows the green circle, and red blinking led. I'm at my wit's end. :crying: It was a gift and I messed it up.
I didn't read everything in this thread, sorry, but just asking, did you try to charge it overnight? My brother had an old, really small Vodafone Huawei Phone and sometimes it just turned off and needed at least 12 hours charging time to turn on again. Maybe just try to let it plugged in for a day. It may help.

Yep, I did. Annoying thing is the screen stays on when it's plugged in, unlike charging. I kept it plugged in to a wall charger overnight, and the next morning the phone was hot (supposedly because the screen stayed on) and the led was blinking still. When I unplugged it it lost power. This is so strange because just a week ago there was nothing wrong with the battery even.
Had the same problem couple of times
Try this...
1. unplug battery
2. plug-in charger (without battery!)
3. when charger is plugged to the phone then plug battery connector
Enjoy
