Xperia Z abnormal battery drainage and Wifi is DEAD - Xperia Z Q&A, Help & Troubleshooting

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] Rebooting and Drain problem

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.

New battery not solving shutdown problem

Z1 lollipop 5.1.1
build n. 14.6.A.1.236
kernel ver. 3.4.0-perf-gd26777b-00851-ga8b7b55 19 november 2015
It all happened a month ago, after an update, the phone battery registered low and the device reboted, and for the first time in the phone history, I saw, at boot, the "app optimization" dialogue, that kept chewing at what battery life was left.
So, I replaced the battery;
at first start, all seemed OK till I hit an app (whatsapp I think) and the phone displaied the low battery warning and went down.
Same, after a full recharge, when pressing the camera hardware button.
Oh, I also had the discrepancy between the charging icon , which reported 100% charge, and after maybe 10min. 50% and, you know the story.
Now, at the very moment I am writing, after a full charge, 24 hours ago, the phone, without the sim and the SD cards, but left on, registers a charge of 93% (only wireless on, to invite some disharge); of course I cannot check the watsapp, but I took some pics, and the phone stays on.
What do you reckon, I am bugged, as android 5.1.1
should I hang on the phone, which, by the way, performs(ed) pretty well, even though marsmallow is not an option, with the 2GB mem. at least in a bog standard state (i.e. not rooted)?
Thanks
A little update: after two more hours, I started using the browser, and after viewing a couple of pages, the phone swiched itself off.
Now, the charging icon, visible, when phone is off, show a 1% charge.
So, the software battery meter, must be well off the mark?
Last addiction: after an hour, the status light is green (phone charged?) and the charge icon, displays a 100% level.
It's your say, now.
I have this problem and battery replace didnt solve anything here too, but I'm on nougat. I hope someone know a solution for this.. But I think It is some kind of hardware problem.
Little update: after recharging, I switched the phone up and let it play some video on youtube;
well, after maybe half an hour, it went down, and as soon as I plugged the charger in, the icon showed 80% charge, which I allready experienced, dismissing it had a fawlty reading, but, with some afterthought , would be in line with the actual battery drainage ( remember that without any activity it stays on indefenetly) and is, as if, some internal mechanism -either hardware or software, is programmed to switch it off at that precise level.
Just a thought, is there somewhere, the level of battery disharge can be set, at our discretion before the device shuts off, say 15%?
I do not seem to find this specific setting, currently.
It is less credible, as time goes by, to think of it as a specific device/brand problem, given the fact that all the major players ware, seems to be affected, and allowing for differences in platforms, the common denominator would appear to be the software itself.
Exact same problem
Some time ago, I replaced my Xperia SP's battery.
The "used, like new" battery I ordered was as bad as the one that was to be replaced, maybe even worse.
I complained, got another-one. This other battery works great.
Remember: There are no "new" batteries out there, just used-ones.
Some are still good, some are dead.
I don't know where replacement batteries that are new should come from... Sony has never sold them as spare parts. I don't know of any company that produces batteries for Sony phones and sells these batteries on the open market.
I only know of third party spare parts for iPhones. Apple has sold only like 20 different models since 2006.
Sony? More like 100.
Producing third party spare parts just isn't profitable in this case. That's the reason why there aren't any.
Any seller who claims to offer "new" batteries lies. At least if he didn't take them from some never used devices.
I'd be HAPPY to be proven wrong because I also need a new battery for my Z1.
Besides, it's no wonder all our phones' batteries die at the same time. They are all the same age and have had more or less the same amount of charging cycles.
Also, it's no wonder they all die the same way (suddenly empty).
They all (more or less) came out of the same factory.
It's like with cars, same model, same problems.
A Peugeot 206 always has problems with the Zylinderkopfdichtung (don't know the English word, the rubber thingy in the motor that keeps water from mixing with oil), some stuff with the wheels or the exhaust flies off because of rust... for the third time in 5 years...

Your allegations, are worth investigating.
[solved]
Very important updates.
There seems to be an "xperia battery bug" which kicks in at every battery change.
After having done all the calibration stuff, I re-opened the phone and took the battery connector off, while the phone was on.
Then, did the same, with the phone off.
After three or four days in which the phone did not seem able to start, (rebooted at the first stages of switching on) the phone magically booted up with, and what's more important there was no dicrepancy, between the battery charge level, shown when you plug in the charger, with phone switched off, and the charge level presented by the software, once the phone is on.
So, do not give up your still worth device!
Only thing I noticed now, is a sligtly faster battery consumption, even in stamina mode;
could it be related with the post above?
Maybe a new custom ROM could fix the problem, now that the phone seems stable.
Similar problem.
Phone shuts down when 2 to 3 apps are working simultaneously. It first heats up and then suddenly dies.
Secondly, it sometimes dies on 60% and other days it can work till 1% too. Sometimes after a reboot, it shows the battery percentage abnormally.
I love this phone so i m not planning to throw it away. On the other hand, i cannot find an original battery in the market.
Just chuck a suitable battery in and do the procedure I described.
My battery is not original either, so no problem.
As far as the battery consumption, it seems to be better now, after a week of use.

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.

Gear S2 battery issue, drain in OS but when docked shows 60%

My Gear S2 operates as normal as it should, however even at idle, the battery drains rapidly. Once the unit is completely dead, I then dock it and it will say 60% charge, which I know is wrong given that the unit will not power on undocked, meaning the battery had been completely depleted. Unit charges normally but I think a bug is preventing it from reaching actual 100% since it believes 0% to be 60%. Is there a way I can fix this without tearing apart the unit or replacing the battery?
same issue
I'm having the exact same issue, did a factory reset today updated all apps still same. I use a basic watch face, turn brightness to 2, everything off except Bluetooth and can get about a day of use . Is anyone else having this issue and has a solution?
Battery dead
So update on this issue, (on the Gear App on the phones most updated version) I went to the basic watch face in gray scale, then turned off all notifications, under gear connection, I unchecked sync wi-fi profiles, and under about gear I unchecked marketing information. I'm not sure which of those if any made the difference but at the end of day one 16 hours of use I was at 70%. So on the second day I tried a colorful watch face with animations, and 16 hours in I was at 63%. So one of those changes I made may have fixed my issue.
I did uninstall and reinstall the app on the phone, as well as reset the watch itself, neither seemed to work until I did the above changes. Hopefully that will help someone, or at least help to find out what is causing the massive battery drain.

With all that I have done with my gear, most I was able to get was about 10 hours. Though today it did to something odd. It died completely like it normally does, (it dies anywhere between 3-10% ish, and when it does die, its completely dead) so I placed it on the dock. Two minutes later I check and it reports 34%, "thats odd" I think to myself so I undock it and power it up thinking I would get no more than 5 minutes battery life on it since it couldnt possibly have that much charge in two minutes. I also expected it to report a low percentage but it didnt. I placed it back on my wrist and it continues to run about 10 minutes later down to 25% and still going! I find it odd. My current leakage issue I think remains and might be why the watch doesnt last as long. I might end up getting a new battery and see. My top battery user: watch faces at ~45%, even if the face hardly came on, and I am using one with a custom background that is mostly pure black.
Drain
That does sound pretty weird. I had a custom watch face installed "Mr Time" and started with a brand new install and I'm slowly adding things back in.
I would suggest a fresh install of the phone app, and the watch, using the classic face black and white. If you can get similar results to what I have then one by one start customizing it. I tried a lot of things to get it to work, over several days and that's what worked for me. I even uninstalled all of the watch faces I want using from the app"i felt that Mr time was still running in the background, even though it probably wasn't.
Good Luck

Weird Battery Behavior

I received my Xiaomi Mi 9 yesterday and after setting everything up I started to notice a fast battery drain, even when the screen is off, which I found to be quite weird for this phone.
When I restarted the device however, my battery percentage was back up again. It somehow went from being at 15% to being back at 73% after the reboot!
I am very confused about this, and I have no clue what could be causing this.
So far I've tried to do a factory reset, which didn't seem to help however. I've turned off WiFi, GPS, Sync and I pulled out my SIM Card and left it sitting, screen off, with occasional checks, but still the same drain.
What's even weirder about this is that the drain seems to be constant. I included a screenshot of the battery history graph, where it is visible that the battery "drains" at the same exact speed every time. Every time you see a spike upwards, that is me rebooting the phone. You can also see that WiFi (and also GPS and SIM Card) was turned off at some point, but that didn't affect the drain at all.
The phone isn't running hot or anything either, it's literally doing nothing, just sitting there draining.
I've let it drain down to 0%, at which point it just turned off. I could immediately start it again and it was back at 66%.
MIUI's battery analyzer thingy does also not have any recommendations as to what to do, except "turn on battery saver", which it says only gains 8 minutes.
I'm running the latest update that I could get through the updater in the settings (MIUI Global 10.2.17.0).
I'm really at a loss here as to how to fix this, or even pinpoint what could be causing this. I would've blamed I faulty battery in my unit, but it kind of seems to be more of a software issue? I really don't know.
It seems that a hardware fault (BSI) rather than a software issue
Cause no one report such a problem with this phone
Do you have any idea which part of the hardware could be causing this?
I said bsi or battery
But refer to warranty for replacement
