[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.

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

It doesn't matter what you're doing, screen on time will always be around 5 hours. If you're gaming, you'll get around 4, and if you're just messaging people without internet, maybe you'll get 6-6.5. Ignore what standby time you get, that's considering you don't touch the phone at all.

I didn't find the "eco mode controller" app but I have an "Extented Standby Mode Controller" app. I FC it and restarted the phone. The estimated standby time was working again

Bro I have the same problme,dine not have the eco mode controller...
I think due to the firmware version..

Stamina mode learns how you are using your phone and creates a profile. Hence at the start it shows quite high backup time. After some time it gathers data about your usage and shows estimated time based on it.
Only problem I have it is that notification led doesnt work. xperia sp biggest selling point isnt working. Sony should fix it.

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

Drain battery on Xperia SP

Helllo, I recently bought my Xperia SP. I really like this phone. I didn't have any problem (wifi). From the first time I bought my phone, I noticed that my battery is draining too fast. I loose every night about 20% battery. Data and wifi are closed and STAMINA mode is turned on. Do you have any solution about this problem? Sorry for my English and Thanks in advance!!

A few people have complained about this, but for me, with stamina on, standby battery life is superb.
Wakelock detector is available in the Play store - this is a useful tool for seeing what's happening to your phone when the screen is off. With WiFi and data on and the screen off, my phone is only awake 6% of the time and it's mostly Facebook (terrible app) doing things.
With the screen off I might only drop 1 or 2% whilst I'm asleep.

Switch to GSM only.
Besides that it seems that an enabled Google Now is leeching a lot of battery too.

1. What ROM (stock?) do u use?
2. What firmware?
3. What baseband?
4. What kernel?
Give us a lil info about what u have in your hands :fingers-crossed:

Well now I unistalled facebook. I'm using stock rom with the latest firmware (.245), without root. I don't have enough apps. Only facebook/twitter and some games. I installed wakelock detector and i saw that facebook is doing the most battery usage.

me either, this sucks, i did a factory reset 2 days ago, at first it was fixed,
but then the wakelocks came back next day, it's the superstamina-xssm again, also with the most alarm

No I didnt done any changes to wifi settings because I didn't have any problem with my Wifi!! I just clean cache on Eco Mode and I will see how battery is going!

i had peretty gud battery life , about 6-7 hrs of sot with wifi on all the day and lots of whatsapping . but now somehow suddenly stamina mod stopped working and getting lots of awake by whatsapp even it is greenified

Same problem here
Xperia SP battery backup is fine when i am using it. But when everything is off and stamina is on at night, i usually lose about 25% of my battery with cellular on overnight !!! But in airplane mode, stamina mode works fine. Only 0%-1% battery drain overnight. I didn't exclude anything in stamina mode. And i always keep my mobile data, wifi off when sleeping. I also checked battery stat but nothing is out of ordinary. But i think cell standby is consuming the power as everything is normal in airplane mode. But why do this happens to me when so many others are fine with cellular on? And the question is, how do i decrease the excess battery consumption by cellular mode when cellular mode is on and mobile data is off? It doesn't make any sense. Any solution for this weird problem? Help me please, this thing is driving me crazy. It takes more then an hour to charge 25% I am not rooted, bootloader locked, completely stock .205 and i have tried flashing and restoring via sus but nothing works. I even formated my internal memory and sd card I am using Xperia SP for about 10 months and stamina mode never worked for me :crying:

Alright i have sorted it out kinda... When um using settings -> GSM/WCDMA, the cell standby keeps draining battery. But when i select GSM only, the battery doesn't drain, lost only 2% over night with stamina on. But i ask this, how the hell am i supposed to use 3G data when the GSM only setting is selected ? Also another thing, the phone is intended for USA market(the customization is customized US). I bought it from Bangladesh and using in Bangladesh. Does this battery drain has to do anything with different Baseband version maybe ? I don't really know anything about baseband and stuff, just a guess. Anyone can help me in this matter ? Shall i flash an Generic INDIA rom ? Because Bangladesh is located besides India...

I have the same problem, maybe its a wrong baseband?

So I need to know can I flash only baseband from 4.1 ftf over 4.3? Because this problem is never exsisted in JB 4.1. :good:

My question exactly. Look at my post (up). My XSP is made for usa market and i am using it in Bangladesh. Maybe that is what causing the battery drain when i use WCDMA/GSM and WCDMA only. But in GSM only, battery life is fine. Not even a single percent battery drain over night. Very huge difference. Now i am downloading a generic indian .ftf to check if it is because of different intended market or not... I will let you know as soon as i am done checking...

I think you can do it as soon as the both rom(4.1 and 4.3) are intended for the same market as the one you are using right now... Because they both will have the same baseband i think. But then, it would make no sense to flash the same baseband. I am not sure though. I am not a developer. You better check with some expert before messing around with baseband....

Yeah, im using an european modded rom on a latinamerican country. Will try New baseband as soon as i have some spare time

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 !

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.

Anyways i dont want to fight with you on this...i helped him with the solution which worked for me...estimated time resets when you clear the data.clearing data is a temporary solution.

Okay
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.

Are you using stock rom? I know the SP can have good battery life on custom roms.
I've searched through all the threads and none of them helped my battery problems at all so I can understand why OP made another thread even if he saw the other ones.

Yes Stock. But today I will change to existenz mod.

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.

Sorry for my bad english

I tried removing most of preinstalled apps but didn't help at all, also I'm using 2g only.
If I charge phone to 100%, enable stamina then go to sleep... in 10 hours I will have lost at least 20% battery similar to what this person describes http://talk.sonymobile.com/t5/Xperi...ometimes/m-p/474409?sl=y&sso_no_log=y#U474409
Do you have c5302, c5303 or c5306? What firmware are you using, 12.0.A.2.254 or older?

When I first time my SP on I have (before doing anything) updated it to newest firmware. Not more. Its C5303.
I cant say anything more. I dont have an issue like you.

Well.. you are very lucky then I've read many other complaints just like mine on other forums
I've been trying to fix this problem for nearly 2 months with no success, there must be some bug in the phone software

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.
