[Q] Xperia Z Battery drain since update .434

Hi everyone,
Since the10.1.A.1.434 update i notice some random battery drain, normally after 12hours of basic usage (20 sms, 30min read news, check facebook...) i got like 60% of battery, but some day after only 5 hours i got 60% and when i look in battery usage, android eat 70%
Someone notice the same bug and know how to fix it ? (Stamina mode is ON)
ps: sorry for my bad english

Yes, i have the same feelings about the battery. It drains for some reason. Couldn't tell if it is for the 434 because I never really used the 350. I eventually turned in my first phone because I couldn't even get to 2 hours screentime before battery died. This second unit is better, but my personal feeling is battery life sucks on the Z. Use it too in stamina mode: it discharged 6% overnight and percentage seems to drop 2 or 3 numbers at a time: I am pretty sure that in my case a good old rooting/nice kernel/ram cleaning/cpu doesn't need to jump at 1 ghz everytime you touch the screen treatment will do miracles as it did with my s3.

Maybe stop using the stamina mode? I read nothing about a draining battery yet. I didn't test this firmware yet. I will if this problem is only to stamina mode users

I'll gonna try some days without stamina mode as you say, maybe it's just a stamina bug.

having the same problem so i am going back to .350

After .434 update, the battery seems to drain a lot slower when unused ( stamina mode enabled ).
After 8 hours left unused, only 1% of the battery drained.

Realy strange... And it isn't a stamina bug, i disable it and i got the same battery drain today. 45% use in only 5h without use my XZ.

Maybe try this http://forum.xda-developers.com/showpost.php?p=40099284&postcount=597

High probability that during the upgrade from .350 that some of your apps are causing issues, I have seen this before with many different phones/roms, something that fixes it for most of them is to clear the delvik cache, then when the phone is rebooting, it forces all the applications to re-optimise. Or the worst case factory reset then re-install/restore your apps from backup

Sorry, that reply was not supposed to be directed to you, don't know what happened there. Sorry should have been directed at the OP

I have backup the phone with the repair tool on pc companion, it's seems to be like a total wipe, everything on the phone have been deleted and the rom have been installed properly. now all seems to be ok, i only lose 5% in 4 hours in stand by with the same applications installed and everything exactly the same like before.

this is a confirmed issue with firmware.434 as i have bought and sold 6 xperia z just to confirm this issue .... my phones lost 20% battert in 8 hours just by sitting idle over night..
I flashed .350 on my 7th xperia z and there is no drain now....
no idea why this is happening. they are saying in another thread that its due to baseband... but how do we flash the firmware without the baseband

Funny,i found it better then the. 350 fw I mean,for me the battery life on fw. 434 is much more improved
One & Only Xperia Z

I was also getting high battery drain out of nowhere on .434. I installed Better Battery Stats and it showed the culprit was something called "wifistatemachine".
I had previously set the wifi to only stay on when plugged in when the phone is asleep. I changed this setting to always stay on and the wifistatemachine wakelock has now disappeared and my battery drain is back to less than 1% per hour in standby. Maybe worth a try to see if this helps anyone else

Battery drain no matter what i do

Even without sim card, the battery still drains, drained 10% every 5 hours. ( even wifi is off it still drains)
According to BetterBatterystats, the highest wakelock count in partial wakelock before is *backup*, (removed after disabling google backup)
The most wakelock right now is SuperStamina Xssm, it can be stopped after disabling Stamina mode, but even i did , this battery still drains.
any way to solve this? airplane mode also drains battery, basically nothing works from stopping battery drain.

in your screenshot you use wifi right?

Try to switch to GSM only (2G) in network settings and see if there's any difference.

How little do you expect the battery to drain? What are the current wakelocks right now? Are they still the same?
Can you use Wakelock Detector instead? The Xperia SP's battery might not be as great as you think....
Let's just calm down, and of course, help can never be demanded. Maybe your phone has a hardware problem that none of us can solve.

Why wait so long?
Take your phone to a sony service center(or where ever you bought the phone) and let them have a look at it, might be that your battery is just not working properly. They will replace if it for you.

they said it's normal for a phone without sim card to standby 2 days without using it
i personally think is software problem, i tried drain the battery down to 0%, then charge it full without break,
after that, the battery drain is just godly, after 2 days left 98%, but then the battery suddenly started to drain like hell,
after 5 hours it became 94%, then it keep draining down as usual.

If all the app draining apps are closed and alsoare bluetooth screen brightness and wifi.
The problem may be deeper.
Your kernel may have flipped and its draining this much battery i am not sure how to check it but i would not suggest you to flash a new kernel right away just because i think thats the problem.

for your information, see this graph, 2 days with good standby, and then went from 95% to 35% in less than 20 hours
this problem is occuring with stamina mode on or off, nothing works

Battery drain issue with new Xperia SP

Hi,
Its been a week since I bought the Xperia SP. The phone came with 50% battery with an estimated standby time of 2 Days. Now, the battery discharge really quickly. With a 100% battery it lasts only for a day (Estimated standby time of 20 Hours). Well I only listen to music on my phone. Brightness is kept at 1/3rd level and mobile data and wifi aren't used at all. I do a little bit of casual gaming. Subway Surfers , to be more precise. That's all. Also when you switch on / off the STAMINA mode, it doesn't effect the battery life. Estimated Standby Time sticks to what it was before switching on the STAMINA mode.
I need help in order to resolve this situation !

Read before you make threads.already many threads about battery life of xsp
For the stamina mod problem do this
Settings>apps>all apps>eco mode controler/extended standby mode controler.
Clear its data and reboot.
The stamina mod should work fine now..do this whenever you find the stamina mod buggy
Hope i helped u

Man.. don't keep saying this like theres a bug with stamina mode.
It's not a bug, the reason his stamina is giving same estimated standby is because stamina is not making a difference, clearing data won't change this....only hide the problem for another few days.
Instead we should try find why his battery life is not good but from my experience this won't be easy... I think there's a problem with the xperia sp's stock rom causing fast battery drain.
@Gamer R - First thing to do is check battery stats for an obvious case. If there isn't one my best recommendation is to restart the phone. This can reduce the battery drain for a couple of days, sometimes restarting doesn't help though.

It might work for you.. but in OPs case it clearly isn't otherwise his estimated standby would be different with stamina enabled.
The phone does calculations related to your usage/battery drain to work out any benefit from stamina, if there is no benefit it won't report better standby time. Clearing data resets these calculations and nothing more...it wont fix any problem so there's no point in resetting them.

I think he wants a real fix though.. maybe you should give a disclaimer saying that its temporary and only fixes the estimate, not the drain

@spix123 & @dipesh1502
Well clearing data of Eco Mode did help in fixing the Established Standby Time. Time to test it whether is it being accurate or not. Right now I have 14% battery left with an established standby time of 16 hours.

Clearing the data cant possibly have any benefit to battery life, I have a similar problem to you and already tried it several times. If it appears to improve battery life then its just the restart which helped (assuming you restarted)
Right now your stamina mode estimate is not accurate, it takes a few days for it to correct the calculation as all data has been cleared.

I've had an estimated standby of 9 days before but chance of that happening is zero
I got this by having over 4 days on battery without using stamina mode then enabling stamina showed 9 days. This was a fluke though.
What is your battery life like? How many days and what usage?

For me Its about 3 days. Some calls. Some angry birds. At start Stamina Mode shows for me 9 days. But stamina mode mod keep data of usage and analyze them. Thats why after some days Stand By time is reduced. Clear data from stamina mode, it will show about 9 days. Don't use (really dont) your device and it can be possibly to make SP working 9 days. WHen I charge my phone in evening with stamina mode on in the morning (after 9, 10 hours) i still have 100%.
And hundert of times. There was a lot of Threads about battery for Xperia SP on this forum, and reeeeeeally lot threads about battery life in Android at all. Just use SEARCH option.

Do you have anything disabled? I don't see how you can get that battery life on stock rom. I've factory reset, tried airplane mode etc.. nothing works, battery just keeps draining mysteriously.
100% after unplugged for 9/10 hours is just impossible. Even when my battery decides to drain slowly it will still lose 5% in that amount of time with no usage.

I have just disabled/uninstall pre installed operator apps, and some stock apps. Turn off bravia engine and gloves mode. And - I use 2G Network only - 3g or LTE Network cant hold battery so long. More traffic - more battery drain.
I use my phone at about 3 months and it still hold 100% during night after full load. More. When I wake up my device in the morning it still have percentage of battery which was when my XP went to sleep.
Stamina mode of course ON.

We have (had - I run eXistenZ now) same software. Some people have this issue some not. I think this is hardware problem. Some batt can be better than others. Its like with for example CPU for PC. Some same models U can overclock a lot, and some make reboots after few steps.

[Q][Resolved] Why does Xperia V battery last so much longer than T/TL?

In the year I've owned Xperia TL (LT30at), I've never been able to get a full day of use (12-14 hours) on one charge except for one week when I had to turn off the data connection (ran out of data allowance). I keep Stamina on at all times but BBS reports at least 3%/hr drain overnight. When the screen is on, the drain increases to 40-50%/hr and that's mostly on auto-brightness, which is minimal indoors.
At the same time, I see posts claiming that their V's are getting good 20 hours of total battery life, which includes 3-4 hours of screen time and minimal drain during inactivity. I understand that the V has a slightly smaller screen and 3G radio, but I can't fathom how that could account for such a difference in performance.
Can someone explain what differences I'm missing?

First things first. Have you compared your XTL's battery life with other XTL users? Or just maybe there are rogue apps sucking every bit of your phone's juice. Check with BBS or Gsam Battery Stats. And again, different people use their phones differently

Interesting. With my TL (lt30a Bell unit though - not AT&T unit), I would get a full day out of the battery, whether I was on stock PL 141 (JB), or the stock AT&T rom (which I think was also JB). Only thing I did on either rom was root/CWM/remove bloat apps manually.

BBS always says the biggest resource hog is bam_dmux_wakelock, which I think is related to wi-fi based location because it disappears when I turn off location. Overall, No. 1 and 2 battery suckers are Android System and Screen.

What is full day of your use? I end up with about 7 hours of standby and 1 hour of screen on before the phone gets to critical battery.

That 3-4% drain in standby has always been there regardless of the ROM. I recently tried a stock-based 4.3 ROM that was draining 10% in standby - that was clearly fixed by another one.

You said that standby drain isn't the problem. I don't know how much nfc needs, I don't think it is that much. Stamina only disables data and background apps, but not gps, as far as I know

My standby drain with Stamina is about 3.5-4%/hour. Is that normal? Compared to the screenshots of XV I've seen around here, it doesn't seem right. On top of that, Stamina app keeps on telling that the phone should last for about 15 hours or 24 hours on standby.

As said before, that also depends on what apps you have installed, and how you've configured Stamina mode, but your bigger problem is your screen on time, 1 hour is nothing. So you should try to reflash the rom. But before you do that you could ckeck the battery, you can find out about your battery health at the service menu

I get straight 2 hours from 100% to 0% of screen with minimal brightness. Also, the unit runs extremely hot when the screen is on.
Battery health is "Good".

This means it is a software problem. Reflash the rom, and wipe all your data. Roport back when you've done this

What is full day of your use? I end up with about 7 hours of standby and 1 hour of screen on before the phone gets to critical battery.
Click to expand...
Click to collapse
LTE: On (of course, but mostly auto switches to the wifi)
NFC/GPS/WIFI: On
Bluetooth: On twice a day (when I use NFC smart tag in the car)
Brightness: Always Auto
Google account (sync always on)
Exchange account (for work emails, always on push)
WhatsApp and BBM accounts
I don't have any old screenshots of my batt. usage, but this was a usual day for my TL:
Unplug from charger at 8:30 a.m.
Glance at work email
Go to car, NFC tag to turn off wifi and turn on Bluetooth
30 mins later, NFC tag to turn ON wifi/turn off Bluetooth
Moderate use throughout the day: occasional whatsapp, bbm, texts. Work email if I'm not at desk, imgur 5 mins, instagram 5 mins, xda premium app for 5 mins (a couple of times a day).
Go to car, NFC tag to turn off wifi and turn on Bluetooth
30 mins later, NFC tag to turn ON wifi/turn off Bluetooth
At home, battery is likely at 55%. Nothing but occasional whatsapp/bbm/texts usually for the evening. By 11:30 p.m. it's pretty well dead at 15%.

Yes. Precisely. I don't understand how nearly identically hardware (the biggest 2 differences being LTE radio & slightly larger screen in XTL) result in half the running time off the same battery.

But dude, the problem is not on XTL in general. I think your phone has some hardware problem. Was the battery life with the previous firmwares (4.0 and 4.1.2) as bad as the recent build?

It has been like that all the time. I realized something was wrong when people started posting significant battery life improvements in 4.3 ROMs and mine stayed the same.

Is the V battery life sufficient for you guys? I've always thought it's a little bit of a stretch if I used it even moderately - I use my V as a hotspot for my Galaxy Note 8 most of the day, and it can barely survive until the afternoon.
That's one of the reason I have been debating getting a Galaxy Note 3 for the extended battery life.

It charges very slow.. I used to charge using my laptop USB.. I kept around 2 hours and charge increased only around 20%.. It was fast in Kitkat.

Oh. Im glad im not the only one facing this. Any solution or we may have to wait for a bugfix?

I tried with Both USA and TW Firmware.. Even tried after full reset.. Still same issue.. I think we have to wait for bug fix or any work around solution ..

I am using the US version, not rooted everything stock. When I installed I faced very heavy drain, even with a charger the battery was going down. After a few reboots everything is back to normal. Battery life is nearly identical to kitkat.
Attaching the screenshots, I am getting more than 4 hours SOT easily with wifi on all the time.

Pretty Impressive Battery life on LP

Battery problem on C5502 (stock 5.0.2 Customized TW fw)
Hey guys,
I think I might have a problem here, I did OTA update over 10.5.1.A.0.283, got 10.6.A.0.454. Everything seems to be working fine, the system is quite smooth, yet battery life is worse than it was!
Cell standby and the OS seem to be consuming way to much battery, my reception isn't perfect, yet I checked in Cell standby and signal loss is at 0%.
I do have STAMINA on, yet according to CPU Spy the phone never goes into Deep Sleep. Isn't that suspicious?
You'll find a few screenshots attached to this post to give you an idea what I'm talking about. I'll try to flash the full rom today and see if it helps, while I'm typing this message FlashTool is creating an FTF file so that I can flash it later. I'll keep you posted.
Also, if anybody needs the FTF file, here's the torrent file link:

I have similar problem. For me the biggest consumption comes from google play service and android system. Really annoying...

From my point of view, it totally depends whether you did an OTA update or flash the new ROM. In my case, I have the Deep Sleep state active for a lot of time, and here's the screenshot:

Did you make a factory reset before/after flashing? Most time this helps.

Think the scan location when wifi is off option (in wifi setting) has effect on the google play service.
Also I am testing what exactly that stamina clock option within stamnia setting does. It seems it affects the battery in a not necessarily good way.
This is annoying. Sony includes all these features that are basically rubbish...

Hi,
I installed lollipop onto my ZR via the PC Companion a week ago, and I used a clean install (repair). My battery life is very bad compared to kitkat. I don't use my phone often, mostly it is in standby mode with mobile data enabled and stamina mode enabled (I added a few applications to stamina mode white list: gmail, facebook messanger, etc.). With kit-kat I had to charge my phone every 3 day, but now I have to charge it every day!!! this is 3 times worse than kitkat. If I check under power management - battery usage, I see a few apps have several hours of 'mobile radio active' (mostly gmail, chrome).
I have searched for this on internet, it looks like it is an lollipop related issue and not a sony related issue. Lollipop has this issue since 6 months now , and they didn't do anything to fix this (there are tons of forums posts about this on reddit, and on other places). I have the feeling Android is getting worse in every new version, and Google hire the most ****tiest developers of all time. They don't even answer to the thousands of user complaints of this issue. I will never touch an android phone in the future.

Disable the stamina mode actually yields better battery life.

Just got my zr update to LP 2 day ago. For now seem like the battery life worse. Need to factory reset after this hopefully that help .

Did India LP update OTA two days back and was surprised see kit ain't charging fast and also discharging quickly. And the main battery consumption was by Album photo analyser services. .. have disabled it and seen significant difference. .
