[Q] Battery Life on Xperia Z. Sucks.

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%

[Q] Is the battery life normal or faulty unit?

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 get 3:45 - 4 hours with 3g on and playing GTA vice city and RealRacing 3 and facebook and whatsapp all day long...I got to this stage by removing google+ which ******** kills the battery..look for apps that drains to much batt power..

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??

Install betterbatterystats from 100 to 10 and post screenshots of partial wake locks and alarms.

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...

Can you also give us screen of the battery usage.
Seems like the phone is going into deep sleep mode alrite.
Have tried enabling STAMINA mode?
Give us a screen of WLD with full battery usage. this is 2hrs in. WLD only tells us the wakelocks. not what apps are actively using the phone. i.e if you were playing say ex.FIFA for 20 mins that wouldnt show up here as it is not causing a wakelock as the phone is actively being used.

okie I did a full recharge..
disable auto sync,birghtness to low, stamina mode on [which shows 4 days 21 hours for 100% charged..it should be way more right??]] ,etc
just played a video for about 5 mins
and was trying to put On data connection (internet) for like15 or so mins...[internet wasnt connecting]
and phone was on standby for like 30 mins..
for this usage phone lost 12% of battery.. is this normal? if this goes on..it will reach 0% in about 6-7 hours...

hi there, hope i can help you
when you said that internet wasnt connecting, is it because you have no internet plans or you didnt have internet coverage? if the latter, i guess that's the main problem, as your hh is retrying connection all the time and not knowing you have no internet coverage..
in my xsp, battery drains to 0% in abt 12 hrs, with medium gaming use and full network connected (no wifi).. in wifi it goes longer, about 1 day

I have internet plan but somehow ticking on data plan for many times, there was no data connection
I've finally switched to other network (company)..
do you keep 2g/3g On in background all the time? i mean even when you are not browsing.. keeping it on just so to get notificaions if someone sends a message on whatsapp/fb?
so under these circumstances, how much long does battery holds?
any other customisations/settings done?

Looks like your battery drain is caused by your phone trying to connect repeatedly IMHO
That 12 hrs is the time with mobile data fully on and no stamina mode.. With stamina mode the battery holds longer, like 18 hrs..
Currently i'm experimenting with llama profiles to imitate stamina mode without losing the led functionality

Battery life??

Hi i have recently had an upgrade of the sony z3 compact "had it 2 days" and today i noticed my battery time has dropped loads compaired to the day i got it?
its saying i get 7hrs on 85% battery no stamina mode
and 17hrs on 85% with stamina mode active
im sure it use to say 1day + with that much charge the day i got it...
Any help would be great! thanks

Stamina gives approximate figures of battery life according to your use
Same for any battery life mode (even standard)
If you have light daily use, it would give more than 2 days and vice versa
Sony claims it can last up to 2 day for moderate/normal use from normal users
I can guarantee one thing its a matter of use
When i use it lightly, i only need to plug phone 2 times by week
When i use it heavily, it doesn't surpass 1 day for sure
Also consider the settings can affect the battery life if you allows any functionality/app/sync/gps/google stuff

[Q] Phone shuts off to 0% when used for over 30minutes (hot)

I have no complains with the speed of my z1 and its reliability. But after awhile (i have been using my phone for 1 year and 4 months now and no complain until now), my phone shuts off to 0% right after usign it for almost 30 minutes of extensive use (playing summoners war/family guy). But from the past yr i have no problem even if its too hot and drains the way it normally should, not until now. it is really annoying. It drains pretty bad from 100% to 70% then 30% to 13% then shutsoff . It still drains even when on sleep right after usign it for 30minutes. For example, playing for like 30 minutes, the battery will turn from 100% to 72% . Then after awhile on sleep for 30 minutes, the battery will be turn to 40-50% then the rest of the history will follow....
Not recently, i have noticed that waiting for my phone to cool off after it shuts off , will have it again another 50% of its life when u turn the power on again.
Before, i charge my phone for like 3 hours , now 1 hour and its full. :/ U Can really see the fault around here.
What to do ?
I have tried using Battery Calibration, Set CPU - all did not work.
This manifested after 2 months now.
Is my battery at fault?
what can i do?
Do i need to use another stock like CM12?
My phone is up to date.
Please i need ur help so badly. Any replies or same situations will help me .

Obviously your battery is at fault.
You battery must have expanded and this will go ON
See at the back of your device where is battery is located. It may have been little changed shape .I.e not flat surface little bugled
Go to service centre ASAP
