Xperia T Battery Problems - Like Never Before - Sony Xperia T, TL, TX, V

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

I have the exact same problem, am about to buy a new battery tomorrow unless someone else has another solution? This might not be the proper forum but in here at least many i9001 users will read it.
I've had this problem for about a week, was very annoying while on holiday. I've tried using BroodROM BE 1.0, Stock KQE and now back to stock KPG.

Well yes I'm going to try a different battery soon but the odd thing is after my battery charge seems to drop down to 5% or so, it starts charging to about its original charge level without a charger connected. So it's basically 80%->drop to 5%->charge back to 60% without charger.
i'll try now to do a hard reset, go back to stock rom, then reinstall an costum rom,
will tell you if it works!
Plz mods remove/delete this sheeyat.. this is

I thought I was the only one with this problem. I charge my battery to full and it starts draining normally. Then, when around 30-80% battery remaining, it turns off. It only turns off when you use it for a while, when the screen is off it stays on normally. After rebooting it turns off within a minute or so. This continues for a few reboots with the battery level remaining roughly the same. Eventually after a few boots it shows 3-4% of battery, after which I of course have to charge. Also tried calibrating and tried different roms but it still remains. I ALSO SWAPPED MY BATTERY WITH A FRIEND BUT IT DIDN'T HELP! It worked like a charm for him but I still got turn offs with his battery.
If i were you Guys, i would install stock rom and hand in my phone under warranty ( of course if you still have it ). Because if this occurs even when u swap battery, let samsung play with you phone then
Its not your battery..restore your phone to the way it was and give it to samsung
i'm getting pissed of now, even with the stock rom it randomly shutsdown.
i don't have any warrenty so i can't give it back to samsung
In case anyone's still wondering, in my case it did turn out to be a fried battery. If anyone else is experiencing the same issues I was, just check your battery to see whether or not it is swollen. If it's bigger than it should be, that probably means it's fried and you should replace it. I'm happily running custom roms without any trouble again now, and battery life is awesome!

Sorry Rajito, but you are having a serious problem, i think the motherboard is the problem, my friend had the same problem with his I9000 S simple. You shoud go to a service !
Hi guys,
I also have this problem, my phone randomly turns off and when I turn it on, it shows much less remaining battery percentage than before. (please see attached image) After turning on the value is increasing, sometimes from ~5% to 30-40% or more...
Now I have CM10 Jelly Bean flashed, but CM9 did the same sometimes but much more rarely than on JB. Today the phone 'died' three times until noon.

Yeah that's the exact same problem I had. In my case it turned out to be a fried battery, see if it's swollen or not, if you lay your battery on a table it should stay still and not wobble around. If the battery's not flat but swollen that means your battery is fried. In this case good news because you can easily replace it

unfortunately it is absolutely not swollen, its fully flat :\
besides this I put out the battery now and put it back and it is showing only 2% percent of battery so maybe my battery is wrong
UPDATE: after uninstalling the pro version of Battery Indicator there were no random shutdowns at all, but the free version is fine o.0

[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.

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'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 ??

Battery issue and restoring completely to stock

Hello everyone,
I have been using a Xperia Z1 for around last 6 months and updated to Lollipop 5.1.1 two months ago. Everything was fine until last week when my phone started to get affected by the battery bug.
The phone works fine and the battery gets discharged in leaps. For example, when I use the phone from 100%, it goes down in the usual way, let's say for 1 hour usage it drops up to 90% which is quite normal. But, when lock the screen and keep it idle for sometime and when I take it back, the battery has dropped a leap, usually by 10-15%.
Yesterday, I was using the phone normally and kept it idle for the entire night and battery has been dropped only from 85% to 79% without stamina mode. That's good. However, when I restarted the phone in the morning, the battery suddenly dropped to 18%. :crying:
I tried calibrating the battery, charging/discharging cycles and removing batterystats.bin. But, the issue is still here.
I think my phone has been affected by the famous Xperia battery bug in Lollipop which means that my battery is damaged. But, before replacing the battery is there anything else that I could do to overcome the issue. Any suggestions are greatly appreciated.
+ My phone is rooted on stock 5.1.1 (14.6.A.0.368) with XZDualRecovery and locked bootloader. If I repair the phone with PCC will it cause any harm or bricking since because of the customer recovery?
Claiming warranty is out of option since the phone has been rooted and flashed with custom recovery.
I don't know why people call it a lollipop bug. There will be a time a battery reaches its end of live. That's what has hit you right now. Your descripte symptoms are from a dying battery. I have seen some dying battery's from me or friends. The battery was holding the charge normally and suddenly no more.
Replace it and all should be fine again.

But, can this happen on a phone that is just 7 months old? Thats what makes me to think that this could be a bug.
I have the same issue, but mine drops to 0% and after waiting some time and booting it the percentage is back up. I have my phone for 2 years now, and the problem appeared in Lollipop also.

It's okay for a 2 year old phone as Lithium batteries wear out with time. In my case, it's kinda disappointing...
So, after searching the entire Internet, I can understand that this is a common issue with Xperia Z1 and Z1 compact and replacing the battery seems to be the only possible solution. I searched EBay for a battery but couldn't choose a good quality one. Can someone guide me on this please?

Your battery is definitely dying and it has nothing to do with roms. Get a battery that the seller claims to be OEM. That's your best bet...

Thanks for the tip. So, I searched for an OEM battery and ordered it along with some tools required for the disassembling. I will keep posted once I replace the battery.

Don't think that it will resolve your problem.
I changed my internal battery about one month ago and when two weeks passed I started to experiment the same bug ? again
It's not only hardware problem, it also software problem, I believe.

You are correct becouse I experience som drops in the range of 5-20% in less than a minute and once 30%. All the time while the phone was in standby mode except once where it did it right in my face (10%). My battery status is reported being fine. I also forced shutdown the phone as per the calibration method for non-rooted phones. Though I did notice dalvik cache wasn't rebuilt and so there is no way to have it refreshed manually except system updates which does this.
Anyway I did remove some apps and did some changes and after this I have not had any sudden drop for weeks. Two of the apps where Truecaller and Facebook official app. Will check though if it was a third one to. I believe one of these or both where playing havok. Especially the Facebook app as it takes liberties I find suspicious, is buggy, can crash the kernel (any app that can do that is doing shady work IMO) and had the addition of a "Video Player" service that was running permanently after you launch the FB app once. I instead use Metal for Facebook now. Pretty much same experience, only 10MB RAM used instead of 90MB and no batter y drain either or any other problem. So in short I believe one of these where the culprits and since many use the FB app that might be the one playing badly with Sony Z1 system.
And If you use Adguard also check if there are apps getting high ratio of ads blocked (or analytics data blocked). Might be some dont get proccessed right in the battery system due to it calculating it wrong. Google Frameworks, Google Contacts, Play Services, Mobilestorage Checker and a few more I disabled the ad filtering for. Though this did not change the battery drop problem previously. It only went away when I uninstalled named apps above.

Z1 Battery Problems

Hi, I have a Sony Xperia Z1 running cm12 nightlies. I've been getting this problem where the phone shows 40% battery but turns off at this and on restart shows 1%
This was okay, however, recently it has started turning off at 70%
I don't really want to replace the battery, as my warrenty is voided (isn't it) and it's not the easiest thing to disassemble.
Thanks.

Don't waste your time on flashing and calibrating. You have classic symptoms of a dying battery. Soon, the phone would shut down at 90%, because your battery capacity is 6-7 times less. Try to run a youtube video and your phone will die in less than 20 min.
If you read this and general threads, you would have found similar complains. You need to replace your battery.

Ugh yeah that's what a quick Google search told me as well
How easy would you say taking apart and replacing the battery in a Z1 is?
Edit: If it's the battery why does it suddenly cut off instead of quickly decreasing.

Because battery is measured by voltage and when voltage goes down to a certain level, kernel shuts down the phone. If your normal battery has 20 cells, yours has only 3 left and voltage goes down rapidly under load, because the other cells are dead. Even if the battery has 1 cell left, when it is charged, the phone will show 100%, while there is a real capacity to hold just a few percents.
Watch youtube videos on how to change the battery. You may or may not break the back pannel (I did). So, get a replacement back glass too.

I had same issue with my z1 since last 4-5 weeks. Thinking that battery is dying I changed it yesterday with a brand new sony battery. Now even after changing my battery, the problem persists. Phone switches off suddenly with 45-60% charge left.
I am on PAC Roam running 5.1.1 . Prior to this I have tried MX rom, Ressurection remix and few other ROMs running 5.1.1 however the same problem wa there as well.
I think it is not only to do with battery but with something else. Please help

You probably have a random reboot issue (thanks to some recent dumb kernel/rom improvements), as opposed to switch off. Look for what your battery shows after reboot: if it is 1%, it is battery related and you got a bad replacement. If it is close to the value before reboot, it is your rom/kernel. There is no third option. And by the way, battery drain has nothing to do with bad battery. Most drains are caused by Gapps and social apps. Also, if you install a new rom or battery, you have to give it a few charging cycles.

Sometimes (like just 10 mins back) my phone goes off and when I reboot it, it comeback with same battery percentage but most times it needs charging to reboot and when it comes back alive, battery stat is 1%
Same was the case with my last battery. Now I am even more confused as to what is the exact cause Should I lock my bootloader and flash Stock 5.1.1. ftf and see if problem still persists?

If your phone boots on its own after switching off, then it is not the battery issue. CM roms are becoming worse and worse for several reasons: too many devices; bad sources from google and incompetent software guys (both at CM and Google). I don't like apple and their products, but when one entity controls hardware and software, you will have fewer bugs. Google pays their engineers for introducing more and more ad related things into Android, as opposed to making Android a full blown operating system.
Go to stock and see how long your new battery lasts: if it dies after 20 min of youtube, you have a bad battery. Period. If it is not, then find a custom rom that does not have random reboots, which unfortunately there is only 2 or 3...
For any measurements to be valid, you need to give your battery at least one cycle on a current rom (from 100% to 15-16%).
P.S. You may have both issues. If you paid $10-12 for a new battery, then most likely, you have a Chinese fake that only looks like real Sony...

I bought it in Rs 1500 (approx $30) from authorized sony service centre which also gave me a warranty of 6 months. Worst case I can return it to them but just want to be sure before I try and do that.
My phone switched on once after going off and it was with same battery stat (last instance). there have been couple of times when I could turn my phone on but it showed only 1 or 2% battery.

Just do what I recommended in the previous post: go to stock, fully charge and see how long the battery lasts on youtube: in 20 minutes, you should lose no more than 13-15% on a new battery, as opposed to go to zero. Some Z1 batteries have a problem: Mine died about 9 months ago. My old Xperia ION (which is a 2012 phone) battery is still going strong (lasts for at least 2 days on Jeallybean).

I just recharge it to 100% and ran YouTube for 35 mins and from 100 it went to 93%..!!
Only 7 battery loss for 30mins YouTube on 240p and full volume
I hope the issue was there for first few cycles. In case if still persists, will try and flash FTF tomorrow and see what happens:fingers-crossed:

That means your battery is fine and you have random reboots related to the rom you use. Here are custom roms that have no reboots: slimrom; tesla, DU and Jaguar. The last 3 are mine. LOL. I am not promoting my roms, don't need to (just look at the number of downloads, especially Jaguar)... In case of Jaguar, you have to flash November 1 kernel on top of the latest release. It is in November that they introduced changes that cause reboots...
Haha..
I know you don't have to plug-in your roms. I guess I will hold it for a day to see how my phone behaves. Major battery drain is when I play Clash of Clans. I am on CoC to check endurance. If not, them will move to Jaguar with Nov kernel on top.
I have realized that it's somewhere in November since there random reboots and battery issues started

I flashed latest Jaguar with Nov 1 kernel and c6902 modem (Version 4). Have also flashed 5.1 gapps (Micro version) and restored all my apps. have created Zip from titanium backup.
Phone still went off from around 75% battery. when restarted again, it came back with 45% battery, just to die within 30 seconds :crying:

Z3 refuses to sleep. Tried everything

Basically, for a couple days, my Z3C battery drain graph is a straight line going down at 40 degrees. I'd post a pic, but I can't yet (new member limits).
It used to be mostly flat when the phone wasn't used, but not anymore.
What changed? honestly, nothing! I just woke up and noticed that it went down from 100% to 70% during ~7 hours of my sleep. And it's like that ever since. I'm struggling to use the phone for a full day (used to be 2-3 days). The phone is 8 months old.
WHat I did already:
1. Turning off/uninstalling various apps based on their % impact on battery drain
2. Clearing cache
3. Turning down wifi and internet
4. Factory reset with data backup
5. FULL factory reset without touching anything after it
NOTHING worked
My only theory is that battery became bogus and I have to send it for repairs... which means at least 2-3 weeks without the phone and a questionable result (they may as well not consider it broken at all).
Anyone have any ideas on what to do at this point? I'm getting desperate
I wanted to sell the phone in a couple months to buy the Z6 compact, but I obviously can't sell a phone with a faulty battery... which means I won't have funds for the Z6. Sigh..

And what about changing NOTHING but just turning the airplane mode ON?
edit: I made a mistake, not OFF but ON!
I had the same problem with my Xperia T and the cause was that I cut the SIM card by myself (from mini sim to micro sim) and I accidentally internally damaged the SIM card. The battery drain was TREMENDOUS and the phone was INCREDIBLY hot that time. I didn't know what was the cause and tried literally everything! Only turning on the airplane mode was stopping the battery drain so I thought maybe the SIM card is damaged. And it was! After replacing one, everything went back to normal.
But what I want to say - your case might be different but... just give an airplane mode a try.
If you are from Poland - check your private messages!
Flight mode does nothing. 100% -> 75% overnight.

Yep, like I said in first post, I did factory reset. Twice, in fact.
The phone doesn't eat more battery - with Screen On, it works like it used to, but there is no "screen off" time for battery: the drain seems constant. The phone obviously doesn't go into sleep mode.
Then try Safe Mode in which all 'foreign' apps are not included in the startup procedure.
- push the power button
- long press the Power Off on the screen
- Then a option to restart in safe mode will appear on your screen
- Now you can chack whether your battery drain is a software or hardware problem

Hardware sadly... the battery drain is exactly the same on safe mode+flight mode as with wifi+internet+all apps I have
I still have some months of warranty... should I send it?

I had the same problem with my z3c when I went back home to Cyprus for the holidays. In Germany my battery drain during the night is 5-6% with Wifi on (no Stamina Mode), but when I was in Cyprus my battery drain went to like 40% over night. Bear in mind my phone is completely stock, with some disable apps here and there. I used GSam Battery Monitor to see what was going on and I saw that my Phone Radio was using almost the same % as the screen was. I'm thinking maybe this happened because of the firmware or something, I'm currently using .264 for Germany, but when I bought the phone it came with the Greek firmware, and I changed it to the German one during the Lollipop updates. Maybe if you tried flashing another firmware?
