Use 2g only if u dont use 3g.

It seams that ur phone remain awake all the time.

C that blue line under the graph.

Do you got this problem after installed certain app?
[Xperia Z Q&A, Help & Troubleshooting] scoopdreams:
Battery life is not great, but it's good for me. However, my Xperia Z is rooted and all the non-essential apps and services disabled (pretty much everything of Sony's).

Can last for a whole day from morning 8am to night 12pm, and still left about 20%. Heavy user, 5 hours screen-on time, surfing, calls, text/whatsapp, and a couple of videos for about 30min.
[Xperia Z Q&A, Help & Troubleshooting] Hellscythe:
think you mean 12am lol..
[Xperia Z Q&A, Help & Troubleshooting] scoopdreams:
lol yah it's not much to crow about if it lasts till only 12pm noon. ;)
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
Hi guys

So I've charged it overnight, and this morning I've purposefully turned Stamina mode off (though the number doesn't change from 20 hours either way, Stamina mode is definitely broken on my handset!)

I've also turned off a load of location service options from within maps, as per a solution I found on a google forum (but it won't let me post the link as I'm still a noob!)

It sounds like lots of people have had similar issues with Android 4.1.2. Dare I hope that Sony release the 4.2.2 update as quickly as rumoured and that this will fix these issues!?

I'll report back in later on the battery use. So far only used 7% since being unplugged at 8:30am, and i have made a few long calls this morning (I use the phone for work as well as play :D)

I really haven't been using Apps all that much at all. I haven't even tried Google Talk yet. I am a games man really, so hopefully I can get the battery life sorted so I can make use of this phone to its full capability.

I don't want to disable 3G as I see this as standard operating functionality, and I usually use my phone to browse the web, check emails, check facebook, use whatsapp, stream youtube vids, everything you would expect a connected smartphone to do. I suppose what I'm saying is I don't want to disable anything that takes away from how I would actually use the handset, otherwise even if the battery lasts, its not doing what I need it to. It would be like a paperweight with a long lasting battery... pointless.

Thanks for all the suggestions guys, I really appreciate all the support. Fingers crossed I get a better day out of it today! Watch this space.

:fingers-crossed:
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
Much better today. I've had to use it for quite a few calls, watched a couple of vids and listened to a couple of tracks plus played about 4-5 levels on angry birds space. I'm at 56%remaining after 9 hours on battery. This is with stamina mode off. 1 hour 37 mins of screen time.

To be fair it's still not as good as I had hoped, but this at least means it'll likely last till bedtime with some battery remaining. I get the feeling that tomorrow it migot be even better. Also I think once the 4.2.2 update is released it will probably improve. I also get the feeling it may have improved after I opened YouTube and Google talk for the first time - almost as if android was holding its breath until I opened them. Could it have been holding out for me to open them so they could complete initial setups or something?

All this being said, after being on here for only about 5-10 minutes to write this post I'm now down to 51% all of a sudden!:confused:

Wrong thread.
[Xperia Z Q&A, Help & Troubleshooting] jkwanness:
Hi there, So did you manage to fix the stamina mode? I'm having the same problem. Turning stamina mode on or off doesn't change the idle time left. Though this is my second day using and only second charge.
[Xperia Z Q&A, Help & Troubleshooting] shakalek:
I believe stamina mode kicks in when You switch the screen on.

On the couple of first day, when You play with Your new phone all day long with full brightness, it could run out pretty quick (less than 9 hours I had).

I got my Xperia Z on release day in UK and to be honest, I've been checking 'battery issues' threads for all day long :o

Two days ago, I did a proper test eg 'everyday use'. Phone battery lasted nearly two full days :good:

Basicaly I upluged Z from charger 6 in the morning and I died on me NEXT day when i sat on sofa around 8 pm watching Youtube with headphones on. So I got over 2 hours constant screen on with music before it died.

Through the rest of the time i managed to get over 2 hours of screen time, answering over 12 calls, sending loads of messages and checking facebook, xda, twitter and instagram countless times :highfive:

1 day 13 hours 24 minutes

And here is the screen time.

My stamina is set to allow gmail only, which obviously tells me if I sold anything on ebay, got interaction on any of my websites.

My screen brightness was set to automatic with slider full to the right.

Vibration when touching screen are off since day one (don't really like it :o)

I was worried about battery too. From thinking it is not good, I've changed my opinion to its WAY better than S and Ip5 (which i own still until i sell them on ebay). Hope this clears things up for anyone. Ohh, phone was ran to flat out once on release day, then full charge and flat 2 times before this.

Now I have to say, I absolutely LOVE THIS PHONE now!

:victory:
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
Is it time to try a custom rom?

Hi there - nope. :( Stamina mode is bust for me. I'm not bothered enough to factory reset again though. I'm still experiencing intermittent battery issues, like today for example I took it out the wall at 6:35, I'm already down to 66%. To be fair, I've watched a couple of 2-3 mins videos on Youtube, used a bit of tethering (about 5 minutes) and sent a few texts, but this is way higher than I would expect. By contrast, yesterday the battery seemed to last pretty well, but then I was working from home, so there was very little in the way of searching for signal etc.

I've contacted Sony about this, and their official line is to download PC Companion software and do a "software repair" (through their usual updating route) I'm going to probably give this a go over the weekend, but it has warned me that I might lose my data... so it might be the equivalent of a factory reset anyway.

I'm a bit sick about worrying about battery life now - getting a new handset should be exciting and I should just be enjoying the features of this superphone. Instead I'm deliberately not using it to make sure I don't run out of juice. Starting to wonder what the point in having it is.

As a newbie, I don't know much about rooting and using non-stock software - does anyone know if:

Its easy to do (I am fairly computer literate at least)?

There are custom roms I could use for the Xperia Z?

It would likely help the battery life?

Thanks again all
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
Well, that's me jealous as hell then! I'm going to do the software repair, as obviously I do have some issues with the battery (rather than me just being paranoid, and it being normal to get the battery usage I've been receiving)
[Xperia Z Q&A, Help & Troubleshooting] jkwanness:
Agreed. I just one good battery life not great. Enough to last a day with moderate-heavy usage. I don't mind charging at night. But charging every half a day is ridiculous..

Anyways I too have my stamina broken. Now i'm doing the software repair. hopefully it'll be okay. I really hope that after a few weeks the XZ can last long..
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
I'm hoping that when they release the Android 4.2.2 update it'll help too. I've read lots of forums about people getting poor battery life when upgrading to 4.1.2 (which the Z comes with as standard) but these being fixed when upgrading to 4.2.2. So hopefully they'll release it as quickly as the rumours suggest and this can help.

I've certainly got no battery problems whatsoever on my Nexus 7 on 4.2.2, but then its a totally different device.
[Xperia Z Q&A, Help & Troubleshooting] Hellscythe:
to be honest, 4.2 and 4.2.1 on my nexus 7 just killed the battery.

it was no where near as good as 4.1.2 or 4.1.1...

hoping that 4.2.2 is optimised a bit better
[Xperia Z Q&A, Help & Troubleshooting] AntonyStark:
Trust me even if the Stamina Mode doesn't look llike it is working there is still a big difference having it off and On, yes the phone is being woken up but still not as much as with it off.
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
Let me know how it goes and also if it deletes data from the handset - I'm looking to do it this weekend; can't afford to not be able to use my phone for any length of time during the week as its my work phone too.
[Xperia Z Q&A, Help & Troubleshooting] decentgi:
i was having the same problem stamina mode worked fine but than for no reason it stopped and i could see the % drop before my eyes, but then i did a factory reset to the handset and it was fine after that works perfectly, def not a solution as there is no need for such a talked about feature to be so unreliable having said that after i did my factory reset i had it on 100% for 5 hours on standby with 15 min of screen time , just goes to show how awsome something is if it worked as advertised
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
Yeah, the factory reset worked for me too... for a day or so. Then boom, went to check it and it was doing the old 20 hours, no difference thing. Real pain the posterior.

In a funny sort of way, I'm glad that others aren't experiencing the same battery issues as me, as it confirms that its something that's not quite working right with my handset, rather than it being as its supposed to be, and hopefully a firmware release or simply doing Sony's suggested software repair will fix it.

On the other hand, it does make me feel that "Why is it always me?" feeling!
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
Also do you have any exceptions for stamina mode? Any apps that you allow to work regardless? Once or twice when I was using stamina mode I would get an error popping up "{{insert app name here}} is stopping stamina mode from working" - have you experienced any of these?
[Xperia Z Q&A, Help & Troubleshooting] decentgi:
no maybe its just an isolated issue with your handset unless there are others out there experiencing that.. i did however experience a funny screen issue yellow lines over the screen for a few seconds.

I think sony released jb knowing these issues but didnt want to risk a repeat of what happend with the sony xperia s being released with ginger bread i hope they fix it becasue i loooooooooooooooooooooooooooooove this handset its really growing on me, all the negative reviews kind of put me down a little but i knew as soon as held it in my hands that i made the right decision.... i cant get enough just hope the battery depleting a little fast is fixed with next update
[Xperia Z Q&A, Help & Troubleshooting] AntonyStark:
After Thowing some pictures to my television last night the dreaded Devices process is back, waking my phone and Stamina Mode is not working as it did yesterday.

I think this is one of the issues, if you use anything remotely connected to dlna, be it album or walkman or something media it can sometimes Start processes that Stamina Mode can't stop, that will wake the phone in Standby. With these processes not on Stamina Mode works much better. All my poor days I've had Media Server or Devices as one of the main uses of Battery, on my good days they were in single figures or not even there.
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
Right I'm going for the software repair option that Sony has suggested using their Update manager/PC companion thing. I've read a few forums about Sony phones in general where people have said they suggest doing it whenever you buy a new Sony phone,so it has to be worth a shot. Just hope I don't lose everything like the factory reset (hope it does more than just a factory reset, as already tried that!)

Fingers crossed. If not I'll be doing a bunch more app installing again (and probably give up on a couple of games that i've made a bit of headway through since the last reset!):fingers-crossed:
[Xperia Z Q&A, Help & Troubleshooting] AntonyStark:
To be honest I'm just going to wait for a Firmware update as people have done the reset only to find the problems come back after a day. We are supposed to be using these functions, and it doesn't even happen every time use use them, so hopefully they can fix it.
[Xperia Z Q&A, Help & Troubleshooting] RavMust:
how long did you own your new xperia z? sony's rule about battery are = battery drain quickly for about 1-2 first weeks, after it feel free to check your battery capabilities again http://xdaforums.com/images/smilies/good.gif

its from my 5 years experience using sony's handset product, sorry for my bad english http://xdaforums.com/images/smilies/tongue.gif
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
Only just over a week. I've just backed up, but changed my mind about the software repair when it told me I'd lose all my personal data. I think I might just wait for a firmware update too. The problem for me seems to be that the Android OS, Media Server and Android System seem to be hogging some battery for some reason. Will just hope that Sony releases an update sooner rather than later.

Thanks for the tip.
[Xperia Z Q&A, Help & Troubleshooting] AntonyStark:
Basically when those proccesses start running you won't get the almost horizontal lines on Stamina Mode, as the phone just keeps on getting woke up by media even though you are not using media stuff at all as the screen is off! These things do wake the phone When Stamina Mode is working, but it happens far less often, so maybe the problem is actually these processes and not Stamina Mode itself, hence they made it to production. you can see in my Graphs in the other thread.
[Xperia Z Q&A, Help & Troubleshooting] AntonyStark:
Stamina Mode worked better last night. Will test it the rest of the day.
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
Yeah still having trouble. I've gotten a few of these messages ( see screenshot), also I haven't even used maps today and my location settings are off, and I've not used any media or Google play apps and check the %! Had stamina mode on all day. Unplugged at 8am

Still a hair over 50% battery left. Looks like decent battery life to me :cool:

Much better than my Xperia S :good:
[Xperia Z Q&A, Help & Troubleshooting] jkwanness:
So my STAMINA mode died again today after reseting a few days go. However other apps doesn't work with fb off, so I uspect its just the expected idle time counter that's off. I won't reset again, just continue using for a few weeks to see how it goes. So far battery life got better compared to the first few days..
[Xperia Z Q&A, Help & Troubleshooting] Silverex:
Brillant, How did you come to that. I would love to duplicate that. Do you have problems with data when you turn the Wifi on or when you have the stamina mode on. My data just seems to die. I have to restart the device.

AW: [Q] xperia z battery issues

Do you have touch sounds enabled, keyboard presses and keyboard vibration enabled, do you have touch dialer keypress sounds enabled?

Go to Settings > Sounds and disable the last 4 options (Dialer sounds, touch sounds, lockscreen sounds, touch vibration). Also in keyboard options, disable keypress sounds and keypress vibrations.

Keep it set that way and check your battery stats for a day or two.

stamina mode

Had the stamina mode issue, was stuck at 10 hours whether on or off. Factory reset worked briefly but went back to only 10 hours. Then did software repair through pc companion and it has been fine for days now. Showing nearly 5 day's with stamina mode on with full charge.
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
This is really interesting. My battery life itself has suddenly become amazing :highfive:

Today I've been unplugged for nearly 4 hours, made a few calls, checked facebook, sent a couple of texts, even installed an app, and I'm still at 96% battery... so for me the only outstanding issue is that Stamina mode is not working properly, or at least not displaying its figures properly.

Can I ask with the repair option through PC companion, did you lose all your app data etc? I have been toying with doing the repair, but don't want to lose all my app data and (call me a nerd) progress in a couple of games. If I did the app backup through the phones backup and restore options will that reinstate the apps I choose when I restore? (I'm happy to reinstall any apps from scratch that I don't have "progress" in)
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
Yes, given you copy the backups to a location which does not get wiped. You may have a look at the PC Companions backup and restore feature.

Or you check Koush's Carbon backup app out in the market. Free version available.
[Xperia Z Q&A, Help & Troubleshooting] AntonyStark:
I might try doing this repair tonight, how long does it take? I have to borrow a computer as my VAIO [lol] is fried.
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
500mb firmware download on your connection + 2-5 minutes of flashing it to the phone.

Be advised, if you of course totally reset your phone, Android reconfiguring and optimizing itself and re-caching stuff will take place again over the next few days. Battery consumption will be high during that time.
[Xperia Z Q&A, Help & Troubleshooting] AntonyStark:
That's fine, just needed to know that the problems went unlike Just a factory reset, people did that and after s day were back to having problems!
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
Doing a repair on a phone, which is booting, which is not rooted and where the /system partition has been left alone, is pointless as it simply equals a factory reset as it "returns" your phone to the state it is in now and additionally wipes your data. As I said, equals a factory reset.
[Xperia Z Q&A, Help & Troubleshooting] AntonyStark:

One thing that has helped my battery life get better was in the Maps app go to settings and disable Location Reporting under Background location reporting and Report from this device, also disable location sharing if enabled. After doing that I have noticed a lot less awake time when screen is off.

Settings > Backup & Reset (?) > Factory Reset

^^ using german locale that is, It's in settings below keyboard and above setup guide, you'll find it.

This is well known to help, if you use Google Now though, it will lessen it's usefulness as certain aspects of Google Now build upon your location reporting and history. If you can't be bothered by this, way to go. Also disable location history, no point in having it enabled with the other two disabled.
[Xperia Z Q&A, Help & Troubleshooting] john_pawson:
Oh right. I was only going off of what another person had said previously here that they had done the factory reset through the handset and the stamina mode had bugged out again on them after a day or so (which happened to me as well) whereas after doing the PC companion repair, the problem hasn't returned at all.

I don't have stamina mode on, because it's stupid for me. I'm using my phone hardly, synchro always on. I have 2,5GB internet limit, so why should I turn off my data. It's smartphone so I would like to have always.internet connection.

S3 have nice power safe option. Deep sleep, low voltage for display and that would be great if XZ will have it.

1. Let the phone settle for a couple days.

2. Reboot eats about 10% including the subsequent rescanning of media, relaunching all apps and services.

3. You didn't lose a word about brightness.

4. But ultimately I judge your experience and battery lifetime to be in line and nothing exceptional.

Either its push, then it's always on, or it's 15 minutes pull. What you said is rubbish.

And it's bad for the battery as well, it wakes the device up at least 4 additional times per hour wasting battery. Set to push if possible.
[Xperia Z Q&A, Help & Troubleshooting] aliguu:
well..

-i didnt mention about brightness because i just had it on standard middle bar with adaptive lighting settings on.

-the email feature says "inbox check frequency", which i set to 15min.

so i guess is pull? not push right?

Unfortunately work email is only POP3, so it seems u cant get push feature with it? (stock client)

Looks like I'll just have to stick with getting it to pull every 10-15min option then...

So in general i m not doing anything else out of ordinary right?

anything else i need to look for to improve better battery?

:eek:
