hello all,
I have been using xperia T lt30a for almost a year and a half, unfortunately I watered my phone because of talking on the phone while it was raining. So that voids the warranty. The screen was so dim that I couldn't even see anything so I replaced it with a brand new one. If you ever opened an Xperia then you know lcd itself consists of 80% of the phone. The phone worked fine for 3-4 months. One day while it was at 30% it died. Restarted the phone and continued to 0% and died. Fully charged it and started using it again...the phone died at 50%, and kept doing that at 50%. Until I completely drained it as part of my troubleshooting and charged it 100%, started using it, now it dies at around between 80-90%, and when it dies and starts up it shows 50% or so. So I charged it to 100%, then dies again same area, it never dies while plugged in even if heavy use. So I was about to order another battery until i checked the "xperia service menu" and ran battery health check. It said "Good, no need to replace it". Whats going on here guys?
I've done all sorts of diagnostics of Google. Dvchek wipe, hard and soft resets etc.settings wipe, Phone repair using PC companion and SUS. Flashing custom ROM, nothing fixed it!
I can not diagnose your phone from remote. But I can say I had read a couple of reports abt the T's mysterious problems, that all were solved after the bactery was replaced.

hey everyone my sister has a milestone and she is having trouble with the phone battery. she says that she fully changes the phone and then at any point, the phone shows the sign that the battery is discharged and then reboots... then the battery shows the charge again, I tried moving from stock to cyanogen which took the problem away for some days but today it happened again. what can it be help!
hmm. i dunno. anyone?
the weird thing is that she just got it back from warranty... the screen was not working
Sounds like a battery problem. I once had my phone show 1% battery-level for like 7 hours (!) before it shut down. Some other time it would show 100% even though it just had been charged for minutes (starting at 5%). I fixed both issues by recalibrating the battery (search the forum, there's lots of info, most OR even have a script for that). I also leave the phone connected to the charger a couple of hours longer even after it says it's fully charged.
But if the phone actually reboots even though the battery has been fully charged, it really sounds like a hardware problem.
try a new battery
Before buying new batteries, just try calibration.
For me, the mentioned case of shutting down with a so-called empty battery was happening only with a stock 2.1.
Since then this issue never occurred again. So a faulty battery is not necessarily the first answer.
Hi,
My battery life/indicator has been behaving very strangely since yesterday, so I'm wondering if the battery is dying. I know about battery calibration, and attempting it hasn't solved anything. I haven't flashed any firmware recently.
When I plug in the charger while on, it almost immediately tells me it's 100% charged, but the number displayed will still be something low, like 50ish. When I unplug it, the number stays. It drops extremely quickly, to around 1-2%, then 0% and turns itself off. After turning it on again, it may rise to 10%, but drop again to 0% shortly thereafter. After a couple of times of turning it back on, it will refuse to turn on. Charging only seems to work when phone is off, but even then the charge won't last much more than a couple of hours of idling - no calls, no web, nothing.
I've tried charging to full while phone is off (drained), and removing battery stats via cwm before booting up. Doesn't help.
Is my battery faulty? It's a very sudden problem, and my battery has been lasting me for days before this happened
So, I got a new battery. The problem persists. I've tried a factory reset/wiping battery stats, but it's still that way. Could this be a hardware problem somehow?
Any advice is greatly appreciated!!
Which fimware are you on? In your case I'd go back to a stock firmware from samfirmware.com and test once again. If the problem persits, you likely have a hardware issue and I'd have it swapped for a new phone whilst within warranty.

I'm using tweaky rom, JVS. I'm not too sure what the local firmware is (Singapore), the one I had before I switched to custom was 2.1, and I don't feel too safe flashing bootloaders when the phone is prone to turning off...

yeah, you are absolutely right. Have you tried betterbatterystats? ( http://forum.xda-developers.com/showthread.php?t=1179809 ) It will show you wakelocks when your phone should be idling.
Did it help ?
Mate, out of curiosity I was wondering if your issue got resolved.
Also, you should check what is draining off your battery.
I tried reading elsewhere and found "Battery Monitor Widget" could be useful for you to identify this.
Nope, still same problem. It's not a wakelock issue, because the battery dies /so/ fast. I can literally charge it to 100%, unplug the charger, and in 30 seconds it says 0% and turns itself off. The phone itself isn't running hot or anything, and seems to be just idling. [Edit: To clarify, it also charges to 100% in about 10 minutes or so. I'm guessing that for some reason the phone thinks the battery is 'full' and stops charging, leading to the quick drop. I've no idea what could cause this though]
I'm hoping that maybe it's a software issue now since the new battery isn't working either (the battery is probably a fake since i got it for cheap, but even then it should last at least a few hours before draining), and that the phone is confused with battery voltage levels or something when I put the new one in.
Anyway, I flashed JVU stock, didn't even root, and will be charging the new battery overnight while phone is off. It says 100%, but gonna leave it on charger anyway. Hopefully if I wake up tomorrow it'll be working :/
If that doesn't work, will be flashing DXJV9 (My original firmware was dxj4), and hope that it's the official one here. Then bring it to a service center and act dumb and hope they can fix it i guess...
Service center replaced motherboard. There goes a hundred bucks :/
This morning my phone seems to be dead. Battery was around 60% before sleep (9h) and now its dead. Plugging in power does actually nothing (no led, nothing). Phone was working properly before :/ Removed SD, removed SIM...nothing..:crying:
A similar thing happened to me about three weeks after getting a new phone. Went to use it about 10 minutes after making a phone call and it was dead, with no signs of life. I sent it to Sony and they repaired it--the battery failed. Be prepared though, it took about two weeks to get it back.
1 hour after i wrote the initial post the phone suddenly came back on!!! I saw a 6h gap in the battery usage stats. However, last night, a few hours after i installed the original fw the phone it died again and did not come back.
However, it's unlocked. How big are the chances to get it repaired/replaced under guarantee?
Do you mean the bootloader is unlocked? I think that voids your warranty. I would confirm with Sony.
am in stock rom.. my phones shut down at 50% .. everytime my phone battery reaches 50% its shutdown... and when i charge its start from 1% and charge very fast.. how to solve this issue.. do i need to replace or flashing/resetting will help
I think it is a faulty battery. In this case I would suggest to change it. :/
I had a battery like that, but not with this phone
It's like this post: http://forum.xda-developers.com/xperia-z1/help/help-battery-life-t3305586
This problem seems to become more and more common around the past few months. Mine started doing this around 20%, but after some weeks it went up to 50%. Some more weeks and now it just shuts off around 96% without even saying "shutting down".
I have tried many things. Recalibrating the battery, flashing different roms, even doing a complete clean flash from a .ftf file. I am afraid we just have to get the battery replaced, or do it ourselves. If your phone is still on warranty you could send it in. Be sure to tell them exactly what happens and when it happens, else they might send it back after some service tests which will make them think the phone is completely fine. I am using an external battery until I take the time to replace it.
Good luck!
...well, mostly.
Started crashing sometimes weeks ago, but dunno if that's related. A few days ago it crashed completely on me, backlight on but no response to anything (OFF button included). Came home, battery seemed to drain, charged up just fine.
The next day - died again, some funky artefacts on the screen first, then same as the previous day except no backlight. Fixed when I came home that day too, started taking it apart and the LED started blinking red (= dead battery). Charged up fine; cleaned up my ROM/kernel too, updated etc., minimal app setup.
Next day again, fine in the morning, then a few crashes aaand dead. Took it apart completely, found out that I get *some* LED response if I unplug the battery and press down onto the motherboard.. Rebuilt it, booted up, crashed again. Seems to turn back on if I mess with it after a few hours, but battery charging is VERY slow (~50 percent in like 5 hours).
I'm going to try flashing stock when/if it comes back up, but I'm leaning towards hardware failure right now - either a damaged motherboard or bad battery.
Most likely getting a new phone anyway at this point, but I'd still be very thankful if anyone would know how to fix this and could share
Welp, that is indeed a very weird problem to me. Sadly I can't recommend anything
Sorry
my xperia sp need 5 hours until full charger:crying::crying::crying: and draining very fast, 2,5 hours only for browsing with data connection
