[Q] What is acceptable 'up time' for the Note?

I've had the Note through GB, ICS Stunner and now official ICS rom....
Stunner was definitely better for battery than the official ICS rom.
I unplug my phone at 6.30am and put it to charge every night around midnight, with battery usually nagging me to charge it - about 10% or so...
My question is that normal? I use my phone normally, the odd facebook and twitter time, a bit of note taking, internet etc...
is 17/18 hours as good as it's going to get?!

yes 18 hours is good, consider the size of the screen etc and how you use it

Mine dies in 9 hours with Wi-Fi on and Auto Sync on. Is that normal?

I would say yes. WI-Fi on means constant power consumption. Auto Sync on means even more power consumption. Wy do you leave them on? You can synch when you need to and switch Wi-Fi on when it's necessary.

Mine is always on wifi and last about 2 days... ^^''

Stunner averages at 16-17 hours, and most people get 17-18 hours if you look at the stunner thread. The best battery life was on stock GB though, 40+ hours for me (light use)

I would think so too with GB...thats what I'm currently running. =)

Measuring total uptime (from charge to charge) doesn't make much sense IMO,
because we all have different usage habits.
Screen on time, however, is a different story.
Anything less than 4 hours of screen on time is bad in my book.

I'm running the german ICS now and after a few tweaks (autokiller) .. i get 2 days of power :d thats with wifi off at work and at Night .. an hour of playing games.. half an hour of voice Calls and some music listening + web browsing. I'm a happy man
@chasmodo: i do listen to music lots with the screen off so screentime is not an absolute measurement of usage either ...
Cpu states However is a very good representation of usage .. minutes 1400mhz..200mhz..Deep sleep ...

Im using LPY rom and for me thet battery time has actually improved compared to official GB. I keep wifi on 24/7 and 2g mode / powers saving, gps off, so on avarage use of around 8h daily, i get more than 24h in one charge.

Yeah since I've done the flight mode and battery pull my up time is amazing! Been on 9 hours now and lost 30% of charge. Very happy with it..

17 hrs so far and battery at 65%. Auto sync, wifi, gps, BT on. Too lazy to turn that stuff off.
Nothing special just stock ICS.

i can only get 16-20h tops... with texting, some calls, gaming and wifi :/ but i've only made 4 charges to the battery yet, so hope that life time will grow up.
using it for about 10h now, and bat @ 55% runing 4.0.3 german ICS

I get more than a day with moderate use. Lots of wifi, FB, a bit of browsing and gaming, some music, a lot of texting and whatsapp, a few calls and just playing around scrolling between homescreens and stuff. Pretty good to me!
Sent from my GT-N7000 using XDA

I find I get on average 16-20 hrs with good use. It really depends on the screen on time as it sucks up most of the power. White especially uses up the most power on these screens. When I check battery stats I usually average about 3-4 hours of screen on time and most of that is web browsing and checking email. Your mileage may vary if you've got background processes
At idle, I lose about 1% per hour (sometimes less if i disable wifi/data/gps/sync). So theoretically I could get over 4 days in idle. With the display on constantly I would guess it would use 15-20% per hour. If you're playing a cpu intensive 3d game you can probably double that or more!
I found cpuspy really helpful in diagnosing battery issues. I was suffering from the deep sleep problem when I moved to ICS LPY (the sounds off/airplane mode/reboot fixed it). The cpu never went to sleep so was eating up at least 5-8% per hour. It might not sound much but if I forgot to recharge the phone at night I would end up with a dead phone in the morning!

Those are still good numbers but from those pics your posted, where the graph goes up it looks like it was charged partially at least twice. Connecting it to any usb will charge it. The battery hours display only resets when it has been fully charged.

Over 24 hours

[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

[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 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.

Strange battery drain

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

The first graph seems ok in terms of battery drain, but still we need to see the expanded one, the one when you click the first graph containing info about the screen, the wifi, signal, etc.
Try to use Gsam or BBS to see the wakelocks or apps than drain most of the battery.
If everything seems normal, then maybe it is a defective unit; try to ask for a change.

There are people that can get more than 10 hours SOT, so it's not crap, something must be draining your battery and you need to find what is it. Obviously if you are heavy user or play games, expect one day of use at most.

I have never and will never get 48hrs out of my phone. If you use you phone with extreme lite use then its possible. But I bought this phone to use. With my usage I get around 18hrs with 5 to 6 hrs of screen on time. For me this is prefect. And if I do need some extra time the turbo charger works great.
