Folks,
Can anyone suggest how much battery life they are getting on their device. Not sure it is a common problem or my device is defective.
It stays on for only 3 to 4 hours and dies, i.e. just a couple of messages and emails (albeit on 100% brightness and NOT on Stamina mode). Is it normal. Brightness to be kept on auto?
If I play video or so, battery goes from 100 to 10% in about 1 hour maximum.
Have juice defender installed. Also a task killer (which kills the background ones and they restart on their own). But not so much help though.
Any suggestions?

Try the battery guru snapdragon app,which works well for me.

Get rid of juice defender, reduce brightness to 75% on usual daily use, and you should get around 4 to 5 hours screen on time, and up to 24 hours standby time.

snapdragon guru is not available for all region But lemme know about ur kernel and model; c6602 OR c6603?
little working with xZ just uses less than 20% in 24hrs
with 50% brightness & Stamina On
Xperia z is either having a software or hardware problem
I use a note 10.1 for two months and did gaming all the time with 3g on but it lasted for two days without charging. But the Z cant even handle 15 minutes of gaming. It goes down from 71% to 62% IN 15 MINUTES. I expected the update would fix the problem. But I dont see any difference. I was so curious with the Z. But I doubt that now. Is the fate of Sony going to be that of like Toyota.

why are you comparing note 10.1 to the sony xperia z are you nuts
http://www.gsmarena.com/samsung_galaxy_note_10_1_n8000-4573.php
your comparing a 7000 mah battery to a 2330 mah you have to be mad to think your going to get the same performance out of the two. i swear some people are full of crap
It's not bad at all.
In the second image, the on screen time was 4 hours. Plus I used out for about 3 our 4 hours of calls.

Reduce the brightness, using 100% is madness.
Root and install greenify then get rid of task killer and juice defense

On 100% brightness I wouldn't expect much more.
From experience I set my screen brightness to about 25%, which is more than enough for normal use indoors. If I need to use the phone outdoors or in sunlight I'll put the brightness up but it always goes back to 25% when I'm indoors again.
The only sync I have on mine is my Google account, everything else is set to manually refresh only.
On my 3rd day of owning the phone I had 24h+ of use from it, and that's still improving. My battery is on about 60% at the moment after 18 hours. If I turn on Stamina Mode it predicts another 2 days!
However, if I was watching videos at 100% screen brightness, I wouldn't expect much more than an hour or two. Horses for courses.
Not Normal

Your situation is not normal. Maybe the battery life on the Xperia Z sucks. Maybe it's all about managing your apps and stuff - but no. Not that much. Playing video shouldn't drain the battery 90% in an hour. I play streaming video over WiFi for 2 hours a day (boring train ride) and leave WiFi on and Stamina mode off all day. Maybe when I get home at the end of the day the battery is at like 30% and maybe I don't play with the phone much once I get to work - but video kills the battery in an hour? Not if it's hardware accelerated video.
I al sure some people will say "See what is running in the background", but I am not sure you would be able to drain your battery that fast even running like @home stuff.
After a few charge and when the battery is season it will be okay
charging
how long does it take to charge this phone? 0-100%

Hi,
Got the xperia z(c6602) for 10 days now, and am little worried about the battery life, yesterday got the firmware update to bulid no 10.1.A.1.434.
and wanted to clarify whether the battery is working properly or not, I got 17hrs 30 mins from the battery with 3g on and in which the phone was not touched for 6hrs,( though is not kept in stamina mode) . Total screen time is roughly 2hrs 30 mins.. attaching pics of the battery stats.. What should be the total display time to drain the battery from 100% to 0%, and how to determine whether this battery is faulty or not

I cant even get such figures in my dreams, playing games is simply out of question, as it drains battery rapidly and google+ is already inactive in my ph. i have attached the pics to show what apps i had been using, simply used ph for checking emails and whatsapp. and screen time is 2hrs 30 mins.. brightness at 20% does it imply i have a faulty battery.
Iam sorry but, I do not think this is bad battery life.
2 hours onscreen 13,5 in stand-by 6 \ 7 % phone calls and your battery is still green.
Not to mention it seems like your 3G is on and you do not use stamina mode.
Kind regards, Stefan.
Does that mean that i have a faulty unit?
Should i take it to the sony service centre, for replacement. ? Need help..
Well no, not at all.
I think the battery life of your Xperia Z is acceptable.
To give you something to compare with:
My Xperia Z is on battery for 12hours and 42 min now.
Battery left: 51%
2hours and 12 min of this are on screen time.
Only use my signals when needed and I do use stamina mode.
Iam pretty sure if you manage you signals properly and use stamina mode you get aprox the same results.
Yours and mine do not differ to much.
Iam pretty sure you could drain any smartphone its battery within 5 hours of onscreen time.
This the Z gives me aprox 4 depending on what I do, Id say its acceptable.
Kind regards, Stefan.

If you install some kind of backgroud task killer your Z gets better results. I got mine with Du battery saver and dx toolbox and got it runnig for 1d16h26m, and it stays it got battery for 3 more days (stamina mode on, all Google backgroud apps, FB apps and a few more are dead ).
I do not want to use a task killer, but freeze apps I do not use using Titanium backup.
3 days standby is easy when you do not much with the phone yes.
I achieved this aswell, just saying 12 hours in standby with 2 hour of onscreen use and 51% left is not bad imo.
Kind regards, Stefan.

But in my case 6 hrs of standby, with 3 hrs of screen time and total 18hrs plus (without stamina mode) is it suffiecient??

I had same problem man..and i was shocked with it.. İ got really disappointed with my battery but after reflashing stock rom with SEUS and full offline charging for like 5 hours am ok with it now but i am still waiting for more with 4.2.2 update!!!

Don't think 4.2.2 is a saviour for the Z. Once my Nexus 4 got 4.2.2, battery life went significantly downhill...
Hi all! First of all sorry for my english
I've bought my xperia z few days ago and I am experiencing a very low battery life, even without using the device too much. First thing I noticed (when I fully charged the device for the first time) was the the standby time approximately only 5 hours with stamina mode (!!!) and a huge battery drain, something like 1% every 2-3 minutes with only mobile connection (GSM) activated and some browsing (no flash only text), no bravia engine, no video, no application in background, lowest possible light screen and of course stamina mode. After about 2 hours 60% of battery remained. Now I have about 5% and I used it for about 20 minutes of browsing, some game (2D), and nothing more.
I ran a test on the battery but seems in good health.
I should re-calibrate my battery?
N.B.
When I bought it I have used it until the discharge (10-5%) of battery then I've made partial charge up to 50-60% then discharge again (10-5%), afterwards a full charge of about 5-6 hours. Can this have damaged the battery?

did you update to .434? because some users say that they got a battery drain when they updated to this version,
anyways, ill give you a solution that works for me,,, install " snapdragon batery guru" really helps alot , and you will noticed some battery improvements, much better than the power management mode,
p.s. dont use it on gaming to much, and dont remove it to charger often ( even when its not fully charged yet)
If the service test say the, battery is fine, it probably is.
Have you tried factory reset?
It sounds like some app is keeping the device awake (and very active)
Try providing some more info, like battery stats.
You should install wakelock detector or better battery stats and see if there's a bad app. And solve it with greenify or uninstall
Sorry I'm quite noob on android, xperia is my first android device I'm coming from symbian
Yes I updated on .434
For the apps keeping awake, I only saw the "battery usage" menu ad it says: Display 46%, Chrome 11%, Android System 11%, Media Server 10%, Standby 4%
Well to begin with de activate chrome, and all syncing.
Settings > accounts > press account & de activate all automatic synchronisation.
For chrome go to apps > all apps > chrome > deactivate.
Then go to play store download dolphin browser

Charge it and see if battery had improved, it should've , charge it to like 20 see how much drains for 60 minutes without using it. Should be 0% or 1%

ok ill try. Some friends told me to fully discharge then recharge for about 12 hours, can this work?
Another thing, I saw some screen of estimated standby time of xperias in the forum, they are all around 1 day, but mine even with a 100% full charge says only 5 hours, what can be?

Thank you!
It worked very well now it says 2 days without stamina and 4 days (!!!) with stamina. Now I can finally enjoy this awesome phone
I've got a doubt about battery discharging in my phone. When it normally discharges from 100 to 35% everything is in normal, with similar drops every hour for ex. 2 days. But (even in standby) when battery is on app 35% I see very fast drop to 25-20% in couple mins. At the beggining I thought it is maybe broken cell in battery but I notice that around camera surface is warm, not hot. So it is probably matter of software. What drains my battery so fast and always at app 35-30%? Do you have similar issues? I made factory wipe few charging cycles ago but it did not make any changes.
Do you use any of the power management settings like stamina more or....
What apps do you have installed?
Sent from my C6603 using xda premium
Yes, I always use stamina, I switched it off just before taking picture. I use dropbox, GO backup, Network Singal Info, netmonitor, Gmail and one additional mailbox. I have Google backup - off, Hangouty - logged off, google now - off.
Well, I don't use stamina mode anymore. I too had these sudden drops when stamina mode was on.
Try switching off stamina for a couple of cycles.
If you find that there are no drops, then you have your culprit.
So you mean not use stamina at all or switch it off at around app. 50%?
Try without stamina mode.

Deleting battery stats does nothing. I post this every time I see someone recommend it, but I feel that the point needs driving home until people realise that it is a placebo at best.

Sorry, it will not improve your battery, just if you have wrong indicated battery %,it maybe solve that. I solved a problem like that.my battery went from 50% down to 18 in a cuple of min.after deleting the stats and a few charges it was O.

No. The batterystats.bin file has no relation to the percentage displayed in the notification bar. It is used to calculate the usage statistics displayed in the battery usage section of settings. Nothing more. The file is deleted every time the battery is fully or nearly fully charged anyway.
The G+ post I linked to was written by an Android framework engineer, so I think they know their stuff

Ok,maybe i'm wrong,but somehow my problem was solved
I am sure that I hadn't wrong percentages but period of strange drain battery (when % suddenly drops) because I felt warm temperature around camera. So I suspect any strange thread/wakelock/trigger.
Ok I just bought an Xperia Z1. Everything seems to work fine except I can not get the Stamina mode to increase to 6 days and more. I've seen people getting it up to 15 - 20 days!
All notifications are off. Basically I turned off everything. Stamina mode @ 100% charge is 5 days & 11 hours. If I turn the Stamina mode off.. Just 2 days and several hours.
Did I get a faulty battery? Any other settings I should know of. I havent downloaded anything from the PlayStore.

First, wrong forum. This is the Xperia Z forum. Despite it being a brother, we can't help much.
However, don't bother about the notification in stamina mode. That never is right. If you don't use your phone days, it'll even show a month of battery. The moment you use your phone, BAM! it goes down to 2-3 days. Don't worry about that. All you have to care about is you're getting the same battery usage others. Not speculated usage but real usage.
Stamina learns from your usage so it shoes approx time your battery will last with your average usage
