Xperia t LT30P reboot problem - Sony Xperia T, TL, TX, V

Hello guys,
My xperia t is facing constant reboot problem. This problem occurs when phone is not charging and when it:
-has both sim and sd card on it. (MAYBE battery problem)
-is on safe mode. (no software issues)
Phone works when:
-it is charging with both sim and sd card on it. ( sim card or tray can't be the issue because it recognizes sim and it works when phone is plugged in hence, battery may be dead)
-it is not charging but doesn't have sim on it. ( this makes me think battery is not the problem)
Update: I have realized that the problem is because of mobile data usage. No reboot when not using mobile data, but as soon as it is turned on and is used, phone reboots.
Anyone experienced this problem and can give me solution please? Phone is not rooted and has stock JB rom.
Many thanks.

Solution - new battery
Hi Shiniix3,
this issue is annoying and very frustrating at the same time because it just begin to appear from nowhere and keeps progressing with every reboot.
During the latest stage of my "try&fail" endless tests I decided to replace the battery and voila! issue resolved. So go and check your local vendor or e-shop, it took me 30 min to replace it myself at home, mainly because I lack special tools for opening and was cautious due to circuits leading above the battery. Also battery is glued to the framework so it had to be done softly but with some amount of pressure when pulling battery out.
Battery life has never been a strength of this phone. Anyway, got a "brand new" phone with fresh energy and CM12.1 working like a charm

If you have electronic skills (or a friend that could do it for you) I resolved with this tutorial: Xperia T Battery Fix

Found this one too, requires some skill and tools. Pretty simple but also switching off battery protection.

Changing Battery causes severe problems.

Hi
On Thursday I received a new battery in the post (my current battery life was abysmal) anyway i changed the battery to charge the new one. After starting the phone i had to select a new language etc. and found that a huge number of my apps were giving the a force close errors. I decided to factory reset my phone, re-downloaded the apps and found the problem resolved.
However earlier today i switched batteries again (wasn't sure that was the cause last time) and it has happened again. Any Suggestions on what is causing it and how to avoid it in the future (other than simply not replacing the battery) or how to rectify it.
Fake/Faulty battery.

No the battery is genuine samsung from a reputable retailer.
If you have to select a new language, it probably means your phone's internal battery has died. Try taking out the battery for 5 minutes, and see if the clock is still accurate.
knowledge is Power. Guard it well.

Are you sure you are letting the phone shut down properly?? When you think it's shut down, press one of the capacitive buttons, if they light up wait until phone vibrates and lights go out, then swap battery. Had the same happen to me a couple of times.
Hello! Me and some other people had similar issues. Read this thread:
forum.xda-developers.com/showthread.php?t=1022044
It looks impossible but I start to believe that a faulty (or a cheap noname) battery can cause problems like this.
I have two spare cheap ebay batteries. I always pop the battery out with the phone still turned on and never a problem...

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.

[Q] Weird battery issue, Razr i, after Jelly Bean

Hi all,
I have weird battery issue with my Razr i xt890 and I'd like some help. I have tried googling for information, but there's too much noise and I can't find anything suitable.
I'm asking on this site because I know the people on here are really knowledgeable.
My Razr i (with Jelly Bean) seems to have erratic battery readings. Sometimes it'll drop to 6%, and then go up to 90%, and jump around to points in between. I have even seen it drop to 1% and then go up to 6% (or something like that).
Needless to say, this makes the phone unusable because I don't know when it's on low battery so I can charge it. Furthermore, twice, it has reported low battery and then automatically shut itself down.
I hope someone can help with this, because I'm really stuck. I bought this phone overseas, and I don't really want to send it back overseas for warranty repairs.
So, some history.
Before the issue:
This is a stock Razr i, running Retail GB software. When I bought it, it was running 81.5.31002.Retail.en.GB 4.0.4. I upgraded to 81.5.39001.Retail.en.GB 4.0.4 and it's been running fine until this issue happened. I normally get about 4.5-5.5 days of battery before I recharge the phone.
This is stock software. No root. No bootloader unlock. No custom roms.
The issue:
I charged up my phone yesterday, and unplugged it from the charger at 100% battery. There was a notification that 91.2.29001.Retail.en.GB 4.1.2 was available. I selected 'Later' because I was busy at the time.
A bit later (maybe about an hour?), I went back to the phone and checked for updates, and selected to download the update. After it was downloaded, I noticed the battery was about 95%, and then I proceeded to install.
I figured 95% power should be sufficient to perform an upgrade.
The install took, maybe 10-15 minutes? At first glance, it seemed successful, but when the phone started up again, the battery reading was at 100%.
I distinctly remember thinking 'This is impossible. There's no way it could be 95% before the install, and 100% afterwards'.
I played around with the phone a bit (to try out Jelly Bean), and after a few minutes, the battery reading dropped to 60% or something.
That's when I knew something was wrong.
Since then, the phone battery reading has been erratic. If I plug it into a charger, it takes a few minutes and then shoots up to 100%. Unplug it, and it drops to a low level within minutes, and then goes up and down like a yo-yo. Twice, the phone went to a very low level, and then shut itself off.
I've tried various charging/unplugging cycles, and nothing has worked yet (Although I didn't have the patience to try an 8-hour charging cycle yet).
Please see the attached images to see what I mean.
The graphs are just bizarre.
I also did a factory reset (from the Privacy menu rather than 'recovery') but that didn't help.
At the moment, I haven't tried to root the phone or unlock the bootloader. I am still keeping the option of warranty open.
I can't think of a reason why this is happening. It doesn't seem to be a simple calibration or battery stats issue. I think the battery is working okay (because it was fine before the upgrade), just that the readings are wrong.
The phone is operating okay in all other respects. If I ignore the battery readings and the 'low battery' alerts, the phone continues to work ... except when it shuts itself down.
Another theory could be that ... because I upgraded without plugging the phone in, perhaps there was insufficient power during the upgrade and caused some corruption, and I have a faulty software/firmware? Not sure how I could test that though.
Any ideas, any one? Please?

Jelly bean download issues
Hi, I have had exactly the same problem after downloading jelly bean. It even died when plugged in charging. As I had only had the phone for three weeks, I took it back to the shop, Phones 4 You, and they exchanged it for a new phone and told me not to download jelly bean until they let me know it's safe to do so. They said that it was a software problem. Prior to this the battery life was outstanding and I am very pleased with the phone. Phones 4 You gave me an excellent service.
Fixed!
For future readers ...
Someone on the motorola forums (see second reply on this thread) mentioned a possible solution which was to manually install the Jelly Bean version again. I decided to give this a try.
After some more research, I discovered that it should be possible to manually apply official Motorola (ie. OTA) updates using the stock bootloader (via the bootloader recovery feature). No unlocking, no root needed.
I gave this a try ... downloaded the software (keeping to the same version), placed it on an SD card, went to recovery and selected 'Updated from external card' (or something like that) and followed through ... and it has worked (Although this time I kept the phone connected to a usb cable throughout the upgrade). My battery readings are back to normal again. I didn't lose any data or apps as a result of this 'manual upgrade'.
And I am presumably still under warranty since I didn't root nor unlock the bootloader.
Other readers may consider trying this for themselves, however, I cannot guarantee that it will work for them. I can only say it worked for me.

The Unofficial Thread of Official OTA Updates

I used the software package from the first post of this thread, labelled as 81.5.39001-91.2.29001.Retail.en.GB 4.0.4-4.1.2 (even though the filename is Blur_Version.81.5.39001.XT890.Retail.en.GB.zip).
I don't have the phone yet (supposed to get it tonight) but having read quite a bit it seems Moto suggests a factory reset after upgrading to JB in order to sort out battery drain etc. I think I saw it in the battery stats thread in RAZR i general.
I send my Razr I back to Germany (living in The Netherlands myself) yesterday! Had the same problem, only my battery get down to 0% all the time, so the phone shutsdown itself every 1 minute till 1 houre. (I'm from the topic: Auto shutdown (battery problem). I think i get my new one next week on wednesday. Dus the JB software manualy update works for more people?

I think the problems described in this thread are relating to strange battery spikes in percentage and not a general drain of battery.
The problem is that everyone seems to be different. Some people report these spikes, some people are reporting high drains (which turning off google now or factory reset seem to fix) and some people (luckily me!) have had no issues at all - just an even faster phone
I did do a factory reset, though not immediately after the first JB upgrade. It didn't help.
I think describing this issue as battery drain or high battery usage is not quite correct. The battery is actually okay*, but the phone's indication of the battery capacity jumps all over the place (and sometimes causing automatic shutdown). I can see how it can be confused with battery drain though, especially if people only observe the reading going down (but didn't see the reading going up).
* At one point, I kept the phone screen on as an attempt to drain the battery. I got about 6 hours screen time (ignoring the intermittent battery low warnings) before I gave up.
Since I now have a phone with JB which is working, my guess is that this bug may not occur in all phones with JB. Instead, it seems to be triggered by something that happens during an upgrade.

i have the same problem. factory reset did not help me and i feel i made a mistake i have choosen this phone.i had motorola mobiles before even bought one to my wife.i know that motorola has a conservative atittude.i thought giving them a last chance now i know it was a mistake
Thanks bengtan.
I was having similar issues and a manual install of JB appears to have solved the issue.
Have you had any luck fixing your phone? I have the same problem since a few weeks ago. Bought a new battery and tried two calibration programs, but the issue persists.
Same here. I am on KK 4.4.2 and have the problem since yesterday. What to do?
Same here, my ROM is cm-11-20160524. After 3 years of usage I thought it's the battery and replaced it with a new one but the issue persists.
This is very odd, I'm here after my dad has the same issue and it looks like I'm the 4th poster to report the issue within 50 days after the thread hadn't any replies for over 3 years! Did any of you recent posters resolve the issue? I had a spare Razr-i and my dad took it to a phone repair shop where they swapped both batteries and the issue was still the same with the other battery, so it seems it's nothing to do with the battery itself for all the posters here so far.
Was there some recent update that spiralled all the phones into the erratic behaviour recently I wonder?
I'm trying to advise my dad what to do:
Try fix the issue on his current phone and keep using relatively old tech phone
Use my spare phone (same type) and keep using relatively old tech phone and try sell old XT890 for parts
Upgrade to brand new phone with latest tech and do him for a few years longer than the XT890 would.
Any feedback appreciated!
The issue flatened a bit now. After 2 weeks of brave usage the phone keeps the charge now normally with rare drops in between. So it's still not on an acceptable level but improved magically. I do not understand the physics of this behavior.
I'm having the same strange behaviour since yesterday!!
battery level drops when pluggin the charger,
after several minutes level is jumping to 100%.
whith unplugged charger, level in general inconsistent jumping up and down...!
could this be SW related? planned obsolescence?
edit: android 4.4.2. systemversion 990.43.74.XT890.Retail.en.EU
I have the same problem following an update to JB I don't even recall authorising
I'm now looking for a copy of the new firmware: 990.43.74.XT890.Retail.en.EU to try to resolve. If anyone knows where it can be found I'd be very grateful if you could point me in the right direction...
Same problem here.
I bought a new battery. No changes.
I than did a complete wipe, unlocked the bootloader and installed CyanogenMod 11 (this one http://forum.xda-developers.com/razr-i/development/rom-unofficial-cyanogenmod-11-t2966855). No changes.
I than completely drained the battery (made sure of it) and left it on the charger over night. Now I don't get those weird spikes, the battery just drains really fast (about an hour an the phone is powering off).
Maybe I try a different ROM, or go back to KitKat
I found this but I dunno how to use it ??

[Q] Battery issue on new phone

Hi, I just purchased a razr i and I am not sure if there's a problem with the battery or if what I am seeing is usual.
I charged the battery fully when I opened it, it then discharged fully within about 8 hours. I fully recharged it, and agaiin it fully discharged in about 10 hours. It is not connected to anything (I don't even have my sim card in it yet), so cannot understand why it is discharging so quickly , especially as it is not doing anything!
As I haven't put my sim in yet (I need to get a new smaller sim card to fit it), could this be causing an issue ? I don't know if maybe its constantly trying to find a network and this is causing the drain problem.
If anyone can shed any light on what's happening here it will be appreciated. I don't want to get a new sim card CID I still get this issue and the have to change back again, and I expected the battery to last a long time based on what I have read elsewhere.
Many thanks
I had the same problem on mine. Check your battery readings, I think cell standby eats up a lot of battery when you don't have a sim on it
Sent from my XT890 using xda app-developers app
Try it in Flight mode for comparison.
Thanks, I'll give that a try and see what happens
There doesn’t seem to be an awful lot out there regarding having no SIM card inserted and rapid battery drain so I think it’s worth a shot.
I think it would also be worthwhile to download BetterBatteryStats to find out exactly where and what is draining your battery, and also to turn off Google Now (with or without a SIM).

Yes, phone manufacturers say this, that your phone will constantly look for a network if one is missing, it does drain the battery significantly. So maybe try it in aeroplane mode and see how the battery goes. Also consider how many hours the screen is on. The screen is typically the biggest battery drain.

S5 Mini G800F Battery Drain Issue

I found another thread with the same issue but no satisfactory answer for me - http://forum.xda-developers.com/galaxy-s5-mini/help/g800f-battery-drain-off-t3445071
A friend's S5 mini G800F suddenly started draining battery - it will completely drain in about 3 hours even when the phone is turned off. My friend claims that nothing changed right before the problem started - no updates, bumps, etc, but I wasn't using it so I can't verify that is the case.
Things I have tried.
- running in safe mode
- wiping the cache
- factory reset
- new battery
- installed cyanogenmod 13.0.1
- battery calibrator app
The other thread was resolved by installing a new mainboard which unfortunately is not an option as I am out of the country currently. With the things that I have tried I am fairly certain that software is not the issue, but I really have no idea where to look when it comes to hardware.
The phone charges normally and works fine as long as it is plugged in and does not overheat but as soon as the cord is unplugged the percentage quickly drains and will continue to drain even when the phone is off.
Any help would be appreciated.
You can install Ampere to monitor both charging and draining currents. But if even with a new and known good battery the problem exists then most probably it's a hardware issue... Good luck.

Ok, I'll give that a try and see what I can figure out.
Unfortunately I was unable to find any useful information with the app. I am left with the conclusion that there is a hardware issue somewhere draining the battery...
the same issue here
It's about two weeks my phone has the same behavior,
I've already tried two batteries from two vendors, but with no success,
In the service they refused to replace the hw, as it would be actually a "new phone"
So I was forced to buy a new one.
As you know, i have same issue. I posted a "fix" but it didnt really do anything.
It turns out its a issue in the usb circuit.
An possible problem-causer could be:
Bad battery
2. Bad sim/sd
3. Bad software (factory reset/reflash stock
4. USB circuit.
So, you would need an hardware repair. It wont cost much, as its only a circuit.
I am gonna repair my phone soon. Ill report what happened then.
Have you been able to fix the issue? Can you provide some details about it?
