xperia z battery issues

Hi all
I'm new to android and am having some major issues with my Sony New xperia z.
First off stamina mode is simply not working. It did to start but it's now not changing the expected battery life when toggled on and off. That's just the start though.
Battery life had been absolutely terrible. I have been deliberately stopping myself from using the handset just so I can make it through the day.
I have come from an iPhone 4 and am quite a heavy user normally, my battery always lasted well beyond one day. New I know the screen and processor on this are awesome but I'm literally not going to be able to use any apps or anything if this is the true battery life.:crying:
I noticed that android os was taking the majority of my battery for just if today, screen has since taken over since I got in because I've been searching the net for potential answers.
Android services is up there as well. I installed a battery checker to see if my phone is but going into deep sleep for some reason and found that there had been something like 3000 wakelocks since last charge (unplugged this morning). I'm now down to 3% after about 13.5 hours since unplugged.
Screenshot was from before I started writing this post.
Any help please. If this isn't some sort of bug/fixable errorI might have to see about returning this phone!
Is this amount of wake locks normal? How can I tell what's stopping my phone from sleeping? I'm new to android other than my nexus 7 which had always been amazing in terms of battery.
Thanks all
John

Try a factory reset or wait for a firmware update.

Thanks.
Factory reset once and fixed the stamina mode issue temporarily but nothing else and stamina issue came back within a few hours. Uh oh battery now 1%
Not wanting to have to reinstall all apps again forma second time. Any other tips? Any way to check what's keeping it from sleeping?

Are you using gsam battery app??
It has all the battery info needed.
Try not to use stamina mode.

I have downloaded gsam - its how I knew there were over 3000 wakelocks but to be honest I've found it all a bit baffling. I'm pretty sure something's happening in the background when it shouldn't be but its like trying to find a needle in a haystack - I'm not sure what processes are what, and what parts of the system should be doing certain things anyway... Does that make sense?
Its dead now, so using my nexus 7 instead. I'll charge tonight, use as normal and monitor it tomorrow. Is there anything I could post from gsam up here that you genius's could help me out with? I bow to your mightier wisdom and plead for help!!! I love my new handset but this is leaving a real sour taste and my excitement and joy of leaving iOS behind me is waning!
Should I use it without stamina mode tomorrow and see if that improved things? Or should I use it as I did today?!
Thanks again everyone for your help.

Maybe you can upload app usage screen and kernel wakelocks.
Reboot ur phone 2 3 times ant Try it tomorrow without stamina mode

Stamina Mode calculation issue

Previously with stamina mode on it would show standby time of a couple if days. Now, it's showing only 14 hours, no matter whether I switch it on or off. So, seems like a problem with the stamina mode calculation. Anyone experiencing this?
Sent from my C6603 using xda premium

I think it learns from your usage.. As mine now only shows 8 when on 7 hours when off
But I get several warnings of apps preventing stamina.. This could also change the calculation
Sent from my C6603 using xda premium

I had this problem more than once, for God-know reason. I found no way but to reflash rom. This miscalculation is no much meaning and affects nothing, so ignore it.

i see this
But don't think about it cause ur phone will properly (battery is healthy 100%)
1. that might be a bug in calculation of estimated time
2. learning how u use ur phone
> the guru app of snapdragon also works based on how u use ur phone.
and i think it will collect required data and refresh itself after 100% charging.
i had 4day
then i got 1days
after that i got 2.5days
and for last charging i got 17hrs
> my opinion; it s about learning
check it urself remember how u use it for last days.:good:

Sv: Stamina Mode calculation issue
I did a repare in pcc and it did it Good
Now the function is good in full charts it gives 4 days and 17 hours
Sent from my C6603 using xda premium

Well still no luck with the calculation even after fully discharging the battery and then a full charge. Maybe it's a software bug. Anyway, I did a factory reset and then restored. Seems ok now but I will monitor and see if it reoccurs.

Hi, the problem is maps app of google, I solved the problem with a factory reset and freezing maps app

Stamina Mode is working properly
*
i had 4day
then i got 1days
after that i got 2.5days
and for last charging i got 17hrs
*
100% charge > 17 hrs
>>> ~ 37% charge > 1day
22% charge > 15 hrs
Stamina Mode learns How you use your phone.
the day before 17hrs i used it alot
after 17hrs i used it alot again till ~70% charge.
then i didn use it for half day So in ~37% power management showed 1 day.
SO There s no problem with battery configuration & NO bug in Stamina Mode.

and then turning it on

Stamina Mode in Xperia T - shame on u Sony

so after update to JB Xperia P has got Stamina mode like in Xperia Z and Xperia T still doesnt?

I don't understand why people are so butt hurt over not having stamina mode.
We have the exact same thing 'extended standby mode' except it's not a fancy graphic... Just a gimmick anyway nothing is different.

I dont really miss it either. Extended standby is great enough, when i dont have my charger with me at night i use extended standby and my battery only goes down 1-2%.

Turn your 3G off, same result. Jesus there are much worse issues, random reboots, bootloaders permanently locked for some unlucky users (me). Every high end phone I use I see a shame on devs who worked hard for months on strict guidelines and crap pay thread wah wah. There will be minor issues with any phone. When you get a bigger fault like my rebooting or the partition error that causes some iconia b1s to brick themselves after software upgrade then complain. Until then buy an iPhone and shut up

yes, there are wakelocks from google services and android system, which you can not get rid off (at least I was desperately trying...)..you get it with all Sony Custom ROMs and all kernels, but also with CM and its derivates like MIUI...
It is mainly Alarm Manager (nothing to do with clock!) and Event Log Service...there are dozens of threads around the forums here, but nothing helped to solve the issues...maybe someone knows a solution

Yup, so i dont blame sony at all. My phone sleeps pretty good after .141 update. Disabling the facebook app and using a 3rd party app also helped a lot with that. That official facebook app is pure crap.

Google can be reduced by turning off "backup my data" and auto sync. As for android system those are necessary functions and it will always be there, the amount it drains depends on the efficiency of both the ROM and the parts (radio etc) in the device. Same goes for mobile standby, except this can be reduced by having 3G off. Basically don't use functions/apps you don't need, that's the only way to save battery

that's not the issue - I know how to save battery. My point: even if you stop all syncs, delete all data-apps, which might be rogue, stop all backup data stuff, maps connecting to Inet, etc. you still have draining the battery by these wakelocks! That's the first and only device I use (besides 2 Sammy Phones and one HTC device), where you can not stop wakelocks!

Sometimes there is just nothing you can do though. My battery life is good enough, every phone will have some wakelocks, for example tegra 3 devices are plagued by baseband_xmm_power, and my desire s had nasty mobile standby wakelocka

I agree.. My cheap Galaxy Ace (with GB) had a much better standby time with sync and data on. Anyway I think we are way off topic here and there doesn't seem to be a viable solution. So I'm out.

Same with the galaxy mini. Its just that cheap designs have parts that don't perform as well, but performance demands juice so the armv6 single core qvga/hvga designs with weak radios inherently use less power anyway, plus the roms are less bloated because of space issues. And yeah, way off topic, even if it does have some relevance

It should work, but buggy. Besides what's wrong with the normal extended mode? Isn't stamina mode just some marketing of the same thing?

Can be the MSM_HSIC_HOST kernel wakelock that is causing your battery drain..

im using 3g all the time and i dont have problems i think u were using your phone differently so you cant compare battery life

There is some strange issue with 4.3 firmware. I've incredible battery drain too.
In early versions i get full one day usege with 3g only network and 3 exchange mail account on push mail settings. Now, nearly 6 hr, and battery low alert.
Realized fast dormacy, disabled for my network, did not solved. Totally uninstalled fast dormacy stiil same. Exchange servise drains all the time.
There is no much wake lock in battery log, there is no special application that drains, but still, like phone does not get in deep sleep state. I dont have and horizontal line in battery stats.
Most of people says, battery is better then before, but most of them do not use phone like me.
Seriously, i consider to revert back 4.2.2
Ps, i even tried to factory default. That was pain in my a.s. because of installing applications and made settings. Still i dont have proper solution.

Stock kernel is so simple developed and doesn't have any real power saving functions at all. Just like Sony throwed some kernel coding together and didn't really test it at all on anything else than stability..
My opinion is this.. Using stock / Advanced stock kernel is like demanding battery issues for free.

Well I've noticed that after a rather short amount of time, a lot of ram is being used and the battery drain is enormous!
Never had so heavy battery issues, even.with different kernels and Roms.
Now.completely on stock and wow.. @ work.for 12 hours, no usage at all, battery dropped from 100% to 36% and energy options telling me that ANDROID OS used 59% THE WHOLE TIME

If you don't know your status of bootloader, most likely it's locked. You can unlock it if your bootloader unlock is allowed. And there's no custom kernel for 4.3 yet.

Did you install anything that might conflict with your Wifi, such as battery saving apps or (very few cases) Ram cleaners? This excludes stamina mode.

If that fails try flashing a different ROM and see what happens

Does this happen to any other devices that are connected to your internet? If not, try changing your phone IP address by going to Settings > Wifi Connection > Hold down Network ( for example, xxx.xxx.x.192 to xxx.xxx.x.188). I'm almost certain this won't fix your problem, but just see if it does anything.
