[Q] Rebooting and Drain problem - XPERIA X8 Q&A, Help & Troubleshooting

I've been ROM-free for months now ever since this problem started but alas! Not even returning it to the stock using Sony's repair thing fixed it.
My phone has been rebooting at random moments and whenever I'm lucky enough to see it on, the battery status always changes. For example, I've recently charged it then put it in my pocket for a couple of hours, when I check it, I see the Sony Ericson logo and when it turns on the battery has completely gone from 90 to 20 something if I'm lucky and 3% or so if I'm not. This problem is often found when: I've left it in my pocket for even the slightest period of time, when someone's calling me (I can't even answer calls for more than a few seconds now because it always dies on me), and other random moments.
If it helps, the battery seems to be on fire every time it reboots itself. Thanks for any helpful suggestions and even for just reading.

Xperia T Battery Problems - Like Never Before

First things first, this is my first time posting on XDA Developers and yes I have searched the forums for a similar question/answer and only found one but my I had a small additional problem as well.
Problem 1) My battery indicator is always wrong, one time it says it's 50% and then I restart my phone and then it says 15%, then I play games until it's 12% and then restart again and then the phone now says 20%.
Problem 2) When my battery indicator is incorrect, when I turn off my phone, the xperia T will just restart and then I have to turn it off again.
What I've done;
- I used sony's repair software online (Sony PC Companion)
- Used ICS format option
- Exchanged Xperia T for another one at Carphone Warehouse 2-3 days ago (Original purchase was last week)
- Drained the battery from 100% to 0% and then charged it again.
NOTE: My Xperia T was bought from UK (Carphone Warehouse) and I haven't flashed it onto another ROM nor have I rooted the phone and the phone is unlocked too.
NOTE 2: I had exchange the phone once and still same problems occurred, dunno if I'm "Bad Luck Brian" this week or all certain xperia T's behave this way.

I have come across the issue of the phone restarting on power off. Quite strange but yet couldnt isolate as to why it does it.
Just gt my phone exchanged due to a suspected bad microphone, and the new one too restarted on a power off.
The previous one seemed quite good with battery life and the new one is yet on the 1st cycle of drain.
Yes, occasionaly my phone does a restart instead of a power off, but i find it quitw usefull because normally I am rebooting to get into recovery and I hate not having a reboot option...
Well done sony
EDIT
The other thing that bigs me is the random reboots...does anyone else get this on stock kernel. I am advanced v3 stock kernel.

Good to hear the restart is a common thing
I've had a random reboot once, while running sat nav sw (sygic).
Today I exchanged my phone to Galaxy Note 2, couldn't be happier.
Also, I've contacted Sony before the exchange (and after this thread was posted) and they said that the issue is known by Sony and it's unknown if it's a software or hardware problem for now, wish you guys good luck and hopefully it's a software bug

In the past month on which I own the device I maybe had one or two random reboots. All stock only rooted. So my guess is its in the advance kernel. Since most people who have it have a unlocked bootloader

I haven't experienced any restarts but my battery level indicator is a bit hit and miss.
I can run my batt down to, say, 5% then turn the screen off and leave it for a while and it'll report something like 15% when I turn the screen back on several minutes later. It will also stay working for AGES when at 1% - my best effort was just under an hour of video with 1% being reported!
I'm sure it'll all get fixed in an update. The T is much more stable than my G-Note was just after release, it took months for Samsung to sort things out on it!
Not random reboots nor battery level issues. Currently in fw 195.
The first 2 weeks of my tx, it could stay at 100% for several hours even over night.
After that, It could stay at 1% for up to 3 hours. Lol
The indicator is not Accurate, but hey, I got pretty good battery life out of TX, around 30hrs per charge.
As for the battery indicator: the percentage is calculated based on the current the battery puts out. The problem with current batteries is, if you pull a lot of energy in a short amount of time (boot/reboot, play game, other hard phone use) the current temporarily drops and thus a wrong percentage is calculated. After a while, the current recovers and the correct value will be shown. Comparable to the fuel gauge showing less/more fuel when parked at a steep hill.
This explains how the meter can fluctuate. What I cant answer is if your phone acts inside the "tolerance margin" or if its way off. My Galaxy Note recently went from 30% to 5% in a couple minutes (I used the hell out of it...) and after I stopped using it, it went back to 15% overthe following 30 mimutes.
As for the other issue, I obviously cant help as I dont possess a X T.

So far battery life seems insane with the extended standby mode... Haven't run a full day yet but it's barely dropping at all for the last couple hours.
Sony T restart problems
Hey guys,
Just looking at sony website, i searched xperia t and in the tutorial it said that holding the power off button turns the phone off while holding the power off button and volume up button at the same time makes it restart. All you guys saying you've got problems with the device re-booting. ITS NOT THE DEVICE ITS YOU PRESSING THE VOLUME UP BUTTON:silly: . A little research never hurts every once in a while!!!!!!!!!!
Noticed the battery percentage peculiarities too... Can't we hide the battery percentage altogether? It makes me anxious.
Had only 1 reboot on the other hand, while going into airplane mode. Phone is pretty stable (build 223).
I was having the same problem + some. Got a replacement TL and it behaves normally Read this post, http://forum.xda-developers.com/showthread.php?t=2355862 if it sounds familiar get a replacement ASAP

That's 3 VERY old threads you have dug up, can I ask the reason why you are doing so?

Xperia Z abnormal battery drainage and Wifi is DEAD

i bought my phone on 1st march and it was all fine (except the stamina mode led notification) until TODAY. I have experienced 2 sudden battery drainage on the same day and the battery can drop like 70% within an hr and the phone became VERY HOT. I have my stamina mode and location based wifi on.
Now my wifi and bluetooth is not working. I have rebooted my phone and switched off the location based wifi and trying to manually turn back on wifi and bluetooth but still failed! the wifi icon keep blinking but never able to turn on again. i also reset and erase everything of the phone and repair the phone once with the SUS. still NO LUCK!
I dunno if the abnormal battery drainage is something related to the location based wifi mode or the overheat killed my wifi or the wifi problem caused battery drain?. Has anyone experienced a similar issue? or just me? heres the battery screenshot.
Hi,
a member (November49) is having problems with their account, but they wanted me to post this for them in the meantime.
Hello mate,
I bought the Xperia Z the day it came out. I sent the first one back because I thought I was experiencing audio issues. The sellers claim they couldn't understand what I was complaining about, as they said caller audio was just fine.. but they sent me a new one anyway. I don't know, perhaps it is my network, because some callers sound muffled or like there is a separate layer of audio over their voices. I might change my sim card because the replacement unit is exhibiting the same behaviour.
Anyway, overheating and power drain. The phone was kind of ok. I was juicing it a fair bit because I watch movies, use the net, HSDPA+ constantly connected etc. All was relatively as expected, then suddenly, I was experiencing a massive power drain and overheating. Overheating while the phone was charging, really small increments in power when charging so it was taking forever, any use of the phone while charging would drain the battery (even though it is supposed to be receiving power), eg connecting to the net, watching movies, checking/sending messages, anything. The problem got so bad, I requested a second product return code from the dealer and was preparing to send it back.
Brain wave - "what if it was a software conflict with an app?". The phone is supposed to be some sort of behemoth and an app shouldn't have such an effect on it, but it was a thorn that felled St Jerome's' Lion. So I went over what I had installed recently and figured it may be a conflict with SystemPanelLite Task Manager. I immediately uninstalled it. Nothing.. no change. Eventually, the phone drained so badly, it shut down. I kept the charger plugged in, let it drink a little and powered it back up. I charged it to capacity. It was limping for a day or two, similar overheating problems and what not, did a second complete drain and shutdown, booted it back up.
Now it seems to be charging as normal, the battery percentage rising as it should, no extreme overheating while charging.. granted it warms up a little, but I'll take that over what was happening before. Tried streaming some video, watching native video, no overheating or exaggerated drainage. I think it's fixed. To be sure, though, I went to Sony's website, downloaded the software update tool, had it check my phone over, it said it was running the latest software, but I opted to do a factory reset and fresh install just to be safe. It recommends you do so if you are experiencing issues.
I'm in the middle of the fresh install now. If no one hears from me again on this issue, you can assume that uninstalling the offending app, draining and rebooting a couple of times and a factory reset fresh software install has fixed the problem. Well... that's what I'm hoping, anyway.
Good luck, buddy.
update: battery was heating up during use, not too much, but getting warm, losing about a percent every minute or two of watching video. Boxed it up. Sending back. I hope the fix worked for you as it did temporarily for me, but ultimately, I think I have a faulty unit.

Random shotdowns (in cold temperature)

I have the phone for a week now and more and more it's shut down when I want to switch it on. I then have to press the power button a bit longer and it will then restart normally.
And there is something else that I think is strange (I just found out while testing because of the other issue). When I press the power button multiple times then sometimes it doesn't switch on again. After a wait of a few seconds and another press it switches on again.
Anyone else has these issues? Can I track why it switches off? Is there a log to see what happend before?
Only when it's cold
I noticed that the random shutdowns are not so random. It only happens when the phone is cold. I can put it 3-4 minutes outside (a bit below 0 degrees celsius) and it switches off every time.
When it's warm - it never happens.
Anyone else have this problem? what's the temperature range which it should work in? I never had that with another phone and it's really not that cold.
Not me, but it's not that cold here.
But it is coldest time since i have z3c and i noticed that in camera when switching from superior auto to manual, or anything it lags a bit when it's cold.
I couldn't find operating range for our battery but it looks like that most Li-Po batteries suffer when temps go below the 0C
I'm going to assume that's your case.
Standby phone = no heat being generated = available current dropping = phone shutting down

weird
thr s always process in background so the phone temp will be always above 0 C
unless the environment temp be too below 0C (like -20C)
contact service center and tell the story and please inform us here what s their response
:good:
Thanks for the inputs. I know that there is a limit on lower temperature for the batteries. But as I easily was able to restart the phone and it showed no strange value for the battery-power, I don't think it can be only this. Also - we had 5 other phones with us and they all worked in the same environment. I'll keep you posted what the service center answers...
I have been in low-temperature environments(-18,+4,0 C) I did not stay too long, but phone survived without any hassle
I am having a very similar issue. Since day 1, my phone randomly reboots especially during the night every 20 minutes or so, and i usually find it switched off in the morning when i wake up. I even had to go work late the first morning because I use the alarm of the phone to wake up and since the phone was switched off, the alarm didn't work.
Last week i went to ski. Up in the mountain, the phone was almost completely useless ( Tempererature was just below 0 C ). It was constantly rebooting in my pocket and shutting down every 5 minutes. Whenever i wanted to use it, the screen opened and as i unlocked the phone it rebooted, however if i continue to use it afterwards ( opened mobile data and gps, talking, etc. ), it did not reboot. So i thought that it might be due to battery getting too cold. Also, i realized the rebooting happens more frequently when i put the phone in a very low power usage state like Ultra Stamina or flight mode. ( I also put the phone in flight mode during the night when i go to sleep )
I have contacted Xperia Care. They assumed this might be a software malfunction and suggested resetting my phone using PC Companion. I played along and reset my phone but it didn't fix anything. I will call them again tomorrow. I am suspecting the battery itself is faulty or the background task that is supposed to heat up the battery is not working properly.
Update: : Appaerently the phone was in fact faulty. They changed it with a new one which is working pretty fine

Heating and Battery issues

Recently, my phone has started running really hot in some circumstances, and the battery runs down really quickly.
Additionally, when the battery gets down to 21%, the phone immediately shuts down and then takes 10-15 minutes, at least, to charge enough that I can boot it back up.
I had a One XL that started experiencing similar issues after a year or two. Do these phones seriously only last that long?

i had no problems with my battery so far, might be worth checking what app is using the battery or accessing the web. I found thats where the most usage occurred.
Oh, it's only while I'm actually doing stuff with my phone, it doesn't just happen in the background. If I leave the screen off, I'm fine. But if I watch videos on YouTube, say, the phone gets so hot it's painful to hold, which wasn't happening before.
Plus the phone shutting off at 21% battery. Which would previously last a good 15-20 minutes, at least, even using it a bit.

i would contact HTC. Since its hardware failure, they usually fix for free (at least in UK) even off warranty.
it could be more than just battery...

Spontaneous Shutdowns

Hey all, I've been having a bit of issues with the Z1 that happened a few months ago.
I just want to clarify what exactly is going on with the device, I've looked into other threads with similar situations but I just want to make sure it comes to the same conclusion.
So the Z1 shuts off near instantly at random intervals being at 80% or 60%.
The thing I never see addressed though is that in deep sleep, my Z1 can last a whole week without issues, the most activity it sees is playing music and nothing more. On airplane mode and everything.
So I just find it strange that if it's dormant, the battery is 100% fine with a very long life, yet upon use for about maybe an hour, whether it's light web browsing or gaming, it randomly goes straight to 0% and dies instantly. When I set it to charge it says it's charged to 60% as if it still has battery. This kind of activity doesn't seem like it's a hardware related issue, or at least it doesn't seem to be related to the battery capacity.
So I figured that maybe it's software related somehow, yet the same issues arise, I've tried stock kitkat and lollipop, AOSP kitkat, lollipop and nougat, and they all have the same issues. One thing I noticed though is that ever since this issue started, I noticed that I can't wipe my data partition anymore.
It mentions being unable to wipe the partition due to encryption or something, even though I've never set up encryption before and for years I've been able to wipe data just fine until a few months ago. Maybe it's related? Do I have some kind of virus?
Just want to clear up any misconceptions before I conclude that I'll need to buy a new battery.
Try command in fastboot : fastboot format data, this may help you
Same here... I was under the impression it more likely happens on camara usage. Some moments later.
Looks like this here:
- Battery is eg 69%
- suddely it says "Shutdown"
- I reboot and it says 0% and shuts down again
- Needs to load a few minutes, then has like 70% after boot.
