[Sony Xperia S, Acro S, Ion] onlavu:
hello. It is pretty clear that the biggest power consumer of my Xperia S is the display. In background running battery drain app is telling me the followings:

when watching just a video (=screen is ON), the average battery loss/hour is 22%. And if I would like to watch a long video on youtube (=screen ON + WiFi), my device would be dead in 4 hours. When playing World of Goo, the battery consumption is aprox. 41% / hour.

But if I use this device just sometimes (few times screen ON just to check emails, a few calls and SMS), it is not a problem to reach almost 2 days / 1 full charge. Before this smartphone I had Xperia Neo (= smaller screen: 3,7"). I used to watch videos too. The battery life was much more better. With Xperia S I am dissapointed a bit (the battery capacity is very low).
[Sony Xperia S, Acro S, Ion] rapsoulis:
After approximately 2 weeks of everyday use of my XS and charging for sure once a day, sometimes 3 times a day due to heavy battery drain from a specific applications/game (GPS on, Data on), I decided to either look for an updated ROM version or change completely ROM.

I moved from PAC v20.1 (if I remember well the number) to the new PAC v22.1.1 (v2 themed). After the first boot and restoration of all applications etc, my battery died in like 4 hours. So I got pretty frustrated and looked into it. I found a thread about CPU Governors and IO Schedulers. I read all the options available and choose what's more suitable for me, depending on my needs.

So I concluded on using the Conservative Governor, combined with the cfq IO Scheduler. It is a little bit lagy the first 5 seconds from the moment you unlock your phone, but then everything is ok.

I'll be back in a few days with a screenshot of the battery use, so you can see the results.

In my opinion at this moment I'm combining very good battery consumption + performance.
[Sony Xperia S, Acro S, Ion] @NUJ:
How to check plz hlp??
[Sony Xperia S, Acro S, Ion] buhonaranja:
Still waiting for STAMINA on XS, but most of people say that is like a Juicedefender.

We'll see on final JB, I hope...
[Sony Xperia S, Acro S, Ion] Felimenta97:
Juice defender uses a bit of battery itself, because it needs to run. That also means some RAM usage. Since Stamina is built into system, it avoids (or minimizes) those two problems.

[Sony Xperia S, Acro S, Ion] phixom:
Stamina is a nice tool to save battery, but it cancels your data connection. If you have some apps with push installed you'll get no messages in it like Gmail until your screen is enabled.

Monitoring messages or someting like this are not received.

[Sony Xperia S, Acro S, Ion] Aniket:
Thats extended standby mode. In stamina mode, you can customize it so that you can still receive notifications from selected applications.
[Sony Xperia S, Acro S, Ion] sdmkx:
somebody did battery upgrade ? or this is not possible in Xperia S ?

If did was it helpful ? what kind of battery ?
[Sony Xperia S, Acro S, Ion] oceanwound:
I havent got any trouble with battery life :D .Mobile network allways on, brightness lever's allways higher than 60% .Form 7AM to 7PM, about 2h for Music ,sometime with gaming.often get 30% to 40% left.And battery drains overnight just only 2-4%.

And i tried many rom form GB to jellybean leked , battery drain still very good
[Sony Xperia S, Acro S, Ion] testadeferro:
Closed batteries have allways the same issue. Fake battery stats. For me in my experience removing fisycally the battery and let it out for 5 minutes uses to solve the drainage. But don't forget this will remove warranty.
[Sony Xperia S, Acro S, Ion] wargre:
Could you explain a little more? How this could solve the power drain?
[Sony Xperia S, Acro S, Ion] testadeferro:
Because you reset the chip when you disconnect the battery from the phone and ler it for five minutes to ensure th e chip sleeps. And when you plug it again fully charged it will be like new again and 100 % accurate. Tested in two different devices (gtp1000) and nexus 7. And according to other people it worked on many others.
[Sony Xperia S, Acro S, Ion] AwesomeARC:
I did some tweaking and go this....
[Sony Xperia S, Acro S, Ion] testadeferro:
Can you put a screen shot from battery history? Its more detailed and can take good conclusions about true battery consumption.
[Sony Xperia S, Acro S, Ion] AwesomeARC:
U mean this one....?
[Sony Xperia S, Acro S, Ion] testadeferro:
Sure. Thanks. And screen time how much did you have?
[Sony Xperia S, Acro S, Ion] AwesomeARC:
3 hours.....and some minutes ....and brightness was at 15-20%.....
[Sony Xperia S, Acro S, Ion] testadeferro:
Its not much. But is ok.
[Sony Xperia S, Acro S, Ion] PLovrin:
For me battery life on ICS .55 is really great since I rooted and blocked some apps.

With less usage I easily get 2 days and without even turning off connections.

Could get even more if I would turn of wi-fi once in a while.

With more usage I have no problems getting up to 20 hours with 4 hours screen on time (some videos, browser, imdb, xda, appy geek, google+, gmail, twitter etc.).

And I have brightness at 50% because there is really no difference between 50 and 15.. But there is difference between 50 and 100:)

We shall see how it will be with official JB update. :D
[Sony Xperia S, Acro S, Ion] zedonetx:
Hi,

Can we solve battery problems of this lt28at?
[Sony Xperia S, Acro S, Ion] vensoni:
hi PLovrin

thank for sharing that with us, can you tell us what kind of appsdo you block ?
[Sony Xperia S, Acro S, Ion] PLovrin:
Yes of course.

Tv.out service, com.sony.ericsson.wakeup

Everything Timescape facebook Twitter related.

To figure out what was waking up the phone I used wakelock detector and terminal to give all info about apps causing wakeups.

To get to this info you write in terminal:

su

cd sdcard

dumpsys alarm > AlarmManager.txt

And you get txt file alarmmanager.txt where all info is written. You see apps and which is causing most wakeups.

For me the biggest wakeup process was tv.out.
[Sony Xperia S, Acro S, Ion] vensoni:
ok, thanks, i will try it and see if it s works for me.

I did this to my phone and managed to gain a couple HOURS in battery life using CM10:
[Sony Xperia S, Acro S, Ion] testadeferro:
You can gain some juice using greenefy app from market.
[Sony Xperia S, Acro S, Ion] @NUJ:
Hey plz can u tell me how to block this apps

My fone is rooted n im havn root explorer
[Sony Xperia S, Acro S, Ion] testadeferro:
Use greenify you have the options inside the app to stop apps that you don't use when screen is off. It's not so deep as to delete system apps or freeze them.
[Sony Xperia S, Acro S, Ion] PLovrin:
And there are also app quarantine and disableservices you can use.

I had some problems with greenify. I froze an app that was constantly waking the phone and was always active and battery started to drop even faster when I greenified it because of endless waking and closing...
[Sony Xperia S, Acro S, Ion] testadeferro:
This can happen. But generally greenify handles good. Maybe some app that had problems with greenify. In that case only a freeze with Titanium backup helps...
[Sony Xperia S, Acro S, Ion] @NUJ:
Can I change the permission of the apps whch m nt using to freze them
[Sony Xperia S, Acro S, Ion] Xenal:
May I ask which app is it?

I'm curious about it ;)
[Sony Xperia S, Acro S, Ion] FireMax_:
Someone with the same problem?
[Sony Xperia S, Acro S, Ion] AMDFenics:
this is only the name for ANDROID SYSTEM sometimes ist Accessory... sometimes MediaScanner, sometimes something else... but its always the system.. but i dont know what app exactly drains battery so much and keeps cpu active:confused:
[Sony Xperia S, Acro S, Ion] PLovrin:
You can get that info. Go back one page I wrote about getting this info in terminal. You will get exactly which process is causing you trouble.
[Sony Xperia S, Acro S, Ion] @NUJ:
Whch app to use to check the battery usage
[Sony Xperia S, Acro S, Ion] AMDFenics:
Thanks for your info, i didn't read the complete thread... sorry :(
[Sony Xperia S, Acro S, Ion] HHarrie:
First of all charge phone to 100%. When it has reached 100% leave it for about 1/2 hour to completly full charge. Then turn off phone, take out cable, turn on again. After that charge phone again to 100%.

Now that's done we can say phone is fully charged. Now let it go empty all the way down so far it's turning itself off. Now turn it on again and wait it's turning itself off again. now we can say phone is really empty :) Now charge to 100% without pause.

I would say battery is now calibrated :) you will see life is better now.

We also just have to wait 4 new updates so we get better performance (more better??)

I recommend

1. not to use a task killer, android can handle this by it self pretty good.

2. Close a app by pressing arrow back and not the home button.

3. As you use facebook, whatsupp, gmail etc. they will sync automaticly, turn off what you don't need.

4. Set your screen brightness as low as good 4 you.

5. Turn off Live wallpaper, it looks very nice yes but it also eats your energy

6. Don't know if it's true but i also turn off NFC in settings, i think this also eats energy and hey.., i can turn my wifi on and off manually as well :)

very nice those taggs, but who needs it?

7. any more? let me know
[Sony Xperia S, Acro S, Ion] ssj_jaypee:
Just wait, as already stated the battery drain is a software bug that will get fixed.
[Sony Xperia S, Acro S, Ion] doministry:
Yes I think it's a software.

And I don't buy all this calibration bull****.

I have an Arc for a year, never ever calibrated the battery and still have amazing battery performance.

New type of batteries don't have to be calibrated.
[Sony Xperia S, Acro S, Ion] Efe64:
Thanks! Im sure gonna use that methods.

Never opened up Facebook, google+ and stuff, deleted all the Updates of them. Still running in background? Im gonna root and delete that apk's. I just dont use it. And dont need it.

Im gonna miss the live wallpaper :(

I can confirm that NFC drained battery on my phone. I left it on and it went from 40 down to 10 in just an hour. -.-

Yep I hope it..
[Sony Xperia S, Acro S, Ion] HHarrie:
We sure need to get ICS soon ;-) every battery, especially new ones, have to be fully charged and decharged to be fully specific and functional to be 100% :-B

Weather Widget

anybody else using the Weather Widget? I feel that it eats too much battery since I have been testing my XS with 3g on and off. Of course the battery would last more by using just GSM but whenever I use the Weather Widget (4 hours refresh) the battery discharges quickly
[Sony Xperia S, Acro S, Ion] gurubumsmack:
I did this, then went to bed with battery at 100%. Woke up this morning and battery had dropped to 85% in 6 hours (erm.. I had fallen asleep on the sofa earlier! :D)

Live Wallpaper was disabled, Wifi off, Bluetooth off. Have the weather widget but set to 12 hour update intervals. Facebook update every 4 hours. Background data on for Gmail.

These are all the things I had setup on my HTC Desire.

Firmware is 6.0.A.37 (as it came out of the box).

Now looking further into it:

And now Android System:

I absolutely love this phone but the battery consumption is a serious issue.

I mentioned that my previous phone was a HTC Desire and thats what I'm comparing the Xperia S to. Granted the Desire was rooted, custom ROM/Kernel but I'd expect the Xperia S to last a day out of the box so to speak
[Sony Xperia S, Acro S, Ion] Goofy-Goober:
but you must root the phone for froze that process?
[Sony Xperia S, Acro S, Ion] MrHenkey:
I am not really happy with the battery life too..hope it improves with build .67,however,when I wanted to perform this update via PC Companion it says my phone is up to date (my current build version is 6.0.A.3.62)..

Is there any way to "persuade" PC Companion to perform update to build .67 or I just have to wait (maybe update is not currently available in my region)?

Thanks
[Sony Xperia S, Acro S, Ion] doministry:
I wait too. Not available here.

SXS Screen

how are you guys getting the screen usage to 5%

plz. help mine is about 85 or 67%:D:)
[Sony Xperia S, Acro S, Ion] dibdin:
What do you have your screen brightness set at? If you have set it to high then you need to roughly set it around 30% to see a difference.
[Sony Xperia S, Acro S, Ion] HHarrie:
Hmmm strange indeed :-S

Let's hope Sony comes with a update soon or they will get some angry people bothering them :-P

Seeing your graphs I might have a closer look in my android system too

Bravia really use that much of battery?

[Sony Xperia S, Acro S, Ion] gurubumsmack:
Mines 5% because I was asleep and the phone by my bedside. Thats what makes the battery drain even worse!
[Sony Xperia S, Acro S, Ion] Super Chimp:
Agree to a certain amount as with my Galaxy Nexus the HD screen on that really did run the battery life, was one of the reasons I sold it in the end.

But it sounds a very similar situation to when the Arc first appeared, as until SE updated the firmware the battery life wasn't so hot, but eventually it had one of the best battery life on any Android device I have had.
[Sony Xperia S, Acro S, Ion] Ambroos:
No. Bravia Engine only changes the way the Gallery app renders images slightly. It doesn't do anything else, and it doesn't affect battery life at all.
[Sony Xperia S, Acro S, Ion] Felimenta97:
So everyone is being silly deactivating Bravia? LOL

[Sony Xperia S, Acro S, Ion] Adibas03:
tried Juice defender. its quite efficient. but the trick is to disable it while your are busy on the phone and re enable once you drop the fone as it even puts of data connection after idle time you set
[Sony Xperia S, Acro S, Ion] tOrNadO™:
Well.. I don knw about the leaked JB.. But with Existenz ROM, m gettin better results.. :)

The one that has 1d long stats was with medium usage and the one with 8h was with heavy usage... As u can see both ran 4h screen, but i did play lot of games and used fb for a long time via wifi and hence battery lasted for only 8hrs.. But still better than SGS2 with wifi ON..

And i used Ondemand governor, min 192mhz and max 1512mhz, Qualcomm's BATTERYGURU app to save battery.. It has given me best results, better than Greenify or One Power Guard.. And also u gotta enable Standby savings in the settings, it will give u better results than when its unchecked.. :)

Indications from what I see with 'stock' kernel are that there is improvements in battery life. A modified Kernel with more efficient CPU governors would only benefit the battery life and increase the time beyond that we see here.

The following shows the battery usage with light use over 2½ days.

Go for Greenify app and freeze those battery draining apps.. It wil hibernate all those apps which drain battery and it opens only when u need em.. Much better backup for me.. I used to lose 1% per hour before.. Now i lost 5% for 9hrs standby during night.. Better isn't it.. Ofcourse i also use Qualcomm's BatteryGuru.. It does caliberate the battery better and saves u some more.. I am easily able to browse more, play more games, listen to music, facebook, whatsapp atleast for half hour a day.. Easily getting the screen to be on more than 4h n i am getting through a day full.. and btw i am on Existenz ROM.. Best ROM so far i hv seen so far.. :cowboy:

The leak build is 6.2.B.200.. The actual firmware is 6.2.A.200.. This leak is just a beta build.. Thats why it leaked out so easily.. The actual firmware will have Stamina Mode because when all the websites were updated to 6.2.A.200, i happened to see Battery Stamina Mode in the list of new features.. It was the last feature they had added.. May be a mistake or may not be.. May be they are gonna give it in the actual firmware.. Hope to see it.. :cowboy:
[Sony Xperia S, Acro S, Ion] FenrirMX:
The people who are saying it won't are basing it on something meatier than "I saw it on the Sony site that said it had released JB on April 24th", which is that Stamina mode requires some kernel code that isn't there in the leaks' kernel.

Basically, making a statement as bold as "Yes the update will come with it.." requires bold evidence to back it up.

That said. I do hope it comes with the update, but I won't be surprised if it doesn't.
