[Sony Xperia S, Acro S, Ion] PLovrin:
As I said I did battery tests with the new Jelly Bean in web browsing and video playback and I must say that difference is really really obvious.

I did the same tests as before with ICS and compared them.

All my tests in browsing were done in dolphin browser with auto reload plugin put on 1 min reload. Website I tested was TechnoBuffalo because it is quite a heavy load. Brightness was at 50%.

To quicky freshen up, my previous results with ICS are found here: http://xdaforums.com/showpost.php?p=37103064 and I will include them for easier comparison.

In ICS browsing desktop pages was really battery consuming so the first test I did was this.

Half an hour of reloading desktop version of TechnoBuffalo every minute did consume 15% in ICS. So in 3 hours 90% would be gone, not a very good result.

But in Jelly Bean the same test ate only 10% of battery. Pretty good improvment right? 1 hour 20% so 5 hours till the phone dies. Almost 2 hours of improvement which is really great.

And next is mobile version. My previous result on ICS was 12% in 30 minutes so in 4 hours you would be left with 4%. Not that good but at least better than desktop sites.

Result in Jelly Bean was so surprising that I had to redo the test once more, because I couldn't believe my eyes. In 30 minutes only 7% of battery was gone so 1 hour 14% and if we calculate, we get 7 hours with 2% to spare. WOW, right? This is whole 3 hours more which is pretty huge improvment.

And I got curious what would really heavy load do to battery usage. I did another test with the same mobile version but with 15 second reload which is pretty hard because it loads almost all the time. It loads the page and there it goes again.

The results aro also pretty good. 10% in 30 minutes so basically the same as desktop site - 5 hours of browsing but I don't know who would load new page every few seconds in real life.

Last test was video playback. I tried 720p video in mp4 and mkv to see if there is any difference. And I also tried if there is any difference between Sony's movie player and BS player. But in all tests I got the same result - 9% in half an hour. So 5 hours with 10% to spare. In ICS I got same 5 hours but with 0% to spare so some improvment is there but not that amazing as web browsing.

So Jelly Bean is a massive improvment in terms of battery usage comparing to ICS and I am really happy with it.

This is all stock right?
[Sony Xperia S, Acro S, Ion] PLovrin:
Yes, updated yesterday via pc companion.
[Sony Xperia S, Acro S, Ion] FenrirMX:
I have to say that was really thorough. Kudos.

As for me, I'm finding it similar to ICS, with my regular usage, which isn't bad, per se, but I was kinda hoping for a little better :P

I did find Facebook being somewhat of an a-hol and keeping my phone awake.

Overall, it's still early, so I'm reserving judgment for down the line.

about battery life xperia sl

battery better after stock .211 and i think that the charging is faster now....thinking of flashing trinity's rom for locked bootloader
[Sony Xperia S, Acro S, Ion] davidbar93:
After 2 cycle charges ,my battery finally stabilized. FastCharge is awesome ,I charged my phone from 0-100% at first time and it took about 1.45hrs. Second time took 1.35hrs .very fast!! Not fast as ICS but still fast.

So here is my battery stats after 2 fully charges(Disabled many(!) apps in Titanium Backup ,including Google apps like Store ,Services and etc... Also disabled "Media Storage" ,it drained my battery a lot before. Many apps hibernated with Greenify(donated version ,system apps can be hibernated too).

"Media" not drains my battery more ,I found that broken mp3 files were the problem ,removed them and everything is fine now. By the way ,Android System drains the battery like hell.

My settings:

*1.7Ghz OC - ondemand both cores + sio(Very fast ,smooth in games also but not battery friendly ,dancedance+fiops will provide better results).

*No GPU OC ,it lags my phone and heats it. Need to be fixed I think ,2D scalling will fix it I think.

*Trinity Kernel V1.5 + Trinity Rom V2.1.
[Sony Xperia S, Acro S, Ion] technaudio:
But with all that disabled, surely your smartphone isn't that smart anymore?
[Sony Xperia S, Acro S, Ion] tuan2d:
Just try some battery saver application and dont forget to put the brightness as low as possible :D
[Sony Xperia S, Acro S, Ion] davidbar93:
It suites me ,I disabled all the crap that I don't use ,downloaded the apps I need from Store before and disabled it. If I need to take a picture/see pictures in album or listen to music I will enable Media Storage again ,not a big problem. Whatsapp is the only app that I didn't hibernated. 340-365MB free RAM always. Smooth experience ,no lags in games and good battery.

My smartphone is smart ,in my ways ,and for things that I use.

Battery

Battery sucks in .200, I'm going back to ICS because the battery can't sustentain the Waze used by 2 hours a day.
[Sony Xperia S, Acro S, Ion] Almutasim:
Same problem with me battery is not going to a long time

however, the mobile itself always suspend and I can't do anything

From yesterday until now my mobile phone Xperia S is not working and suspending

I am going to tell the truth Sony company is a bad company especially in customer care no one response to me about my problem from December,2012 always write about my problem on my device.

Many drawbacks on Xperia S and until now not solve. We are waiting Jelly Bean version from march and even today no update is released in Oman.

Also, network is bad and I compare this mobile with my previous device from Samsung an I see the big difference although was with poor feature.

I regret to myself because I bought this mobile (Xperia S)

something I am not mentioned in my previous post that is no option to change the font in Xperia generally

this features is too important to me because I am using Arabic language as default language so I can select the appropriate fonts and some applications shoe me intermittent fonts.

Small features ignored in Android Operating System that specified to Sony increase the drawbacks of their devices

Please then please then please if anyone programmer add the font option as soon as possible http://xdaforums.com/images/smilies/silly.gif
[Sony Xperia S, Acro S, Ion] PLovrin:
There is no need to put brightness low and hurt your eyes ;)

There was no difference between 15% and 50% brightness in my tests. Take a look: http://xdaforums.com/showpost.php?p=37103064

---------- Post added at 02:26 PM ---------- Previous post was at 02:07 PM ----------

In addition to my previous results found here there is really great improvement in Jelly Bean, at least with browsing (websites, xda, tumblr, google+, appy geek, play store etc.)

Today I used my phone as usual (all of above) for 1 hour and then checked my usage.

And 17% for my regular usage in one hour gives me total of 5 hours and still 15% left. This is very good improvement because in ICS I couldn't get more than 4 hours.

But it is also always awake just like in ICS. And as MaxPayne3004 posted in his screenshot, sometimes it doesn't fall down not even a bit but sometimes 20% or more fall down in a few hours. This is really weird because it isn't consistent not even day by day. I was thinking if restarting will help, but sometimes it does and sometimes it doesn't.

I am still on JB .200 not rooted. I wonder if the same processes as in ICS are keeping it awake. I had them blocked in ICS and battery was great in standby.
[Sony Xperia S, Acro S, Ion] onlavu:
guys. I think we can agree that the #1 power consumer is the display when its ON. Even if you turn OFF data, fix the battery leaks, disable garbage apps, reduce background services, use wifi wisely just when you need it, but still the display drains your battery the most (approx. 22-30% per hour). Sure if you turn GPS on it drains your battery a lot. But why having GPS runing in the background if you dont need it at the moment? The same is the bluetooth. Use it just when you need to transfer something, but not having BT on permanently. That is fact that the display consumes a lot of power, but there is nothing to do with that (OK, to reduce the brightness, but still the display is ON). My point is that there is no way out and we have to accept it OR to buy another droid with better battery performance (and there are plenty of these)
[Sony Xperia S, Acro S, Ion] PLovrin:
No, you are wrong. If display would be the biggest consumer you would get constant drops while browsing or watching videos or just idling with screen on. But this is not true.

In ICS I did a test with only screen on (not touching anything), 50% brightness and it would go for 8 hours. While browsing it was 4 hours and watching videos around 5 hours.

Now, in JB the same tests (except screen on, I will do it today and post results later) I got the result for browsing 7 hours and video watching 5 hours with some battery to spare.

If you would be right improvement from ICS to JB wouldn't be possible because display would eat all the battery. And I don't know how your display eats 22-30% per hour..

And as I said before there is absolutely no difference between 10% and 50% brightness...

DoomKernel is very battery friendly! Screens are from official .200 with DoomKernel and some undervolting. Wifi off when screen off and without 3g. Actually, no heavy usage, no games etc, but awesome anyway.

200 years later and this thread is still going...:P

I think the problem with the XS is Sony just could'nt(or wouldn't) fix the wake lock bug.

Just to give you guys an idea of the wake time on my current phone, heres a screenshot.

I just gave up on my XS and upgraded.

First time I saw this, I was puzzled. My screen time is more than my wake time!!!

Funny...
[Sony Xperia S, Acro S, Ion] Android_UK:
I have found using the following ROMs I get these average times. Bear in mind i'am a medium user.

CM 10.1 RC0 - about 15 hours

Trinities 4.1.2 2.4 using 1.9 kernel roughly 1 day.

EOS - 15 hours

The battery timings are not that bad.

Solution to Xpeira S Battery Drain Problem

Solution to Xpeira S Battery Drain Problem

​

This is really annoying when you have charged your cell phone to 100% and after an hour you take a look at your phone 5 to 10% of its battery is gone with a very moderate use. This problem amplified after Jellybean update to OS in May-June 2013. Here is a solution I have found searching on internet and hit and trial.

Step One:

Drain your battery to 100% till your phone shuts off. To do that quickly you can turn up the brightness to the fullest and watch a movie or browse internet or play games or whatever you want to do. Take pictures if you want.

Do this at least three times, this way software will calculate the battery charge and discharge accurately.

For some people this should solve the problem but if it doesn’t then move on to the second step.

Step Two:

Go to the settings > Back up and reset > Settings reset.

Restart the phone and turn off the "Extended Standby Mode".

This step will reset all the settings without erasing user data. This step worked for me. After this step my battery is behaving normally. After two days of very light usage more than half of my battery is still left. With moderate to high usage you will easily get 10 to 12 hours on your battery.

Step Three:

If step two doesn’t work for you than just back up your data and do the full factory reset. Update your software to the latest Jellybean version. This will definitely solve the problem.

If it doesn’t then there might be a problem with the set. To resolve this issue you should contact official warranty centre in your respective countries.

Please provide your feedback here.
[Sony Xperia S, Acro S, Ion] malcohmx:
A simple full recharge cycle should do the trick. And if you guys really hate the battery life, root your phone and install apps like

Greenify ( stops apps from uselessly running in the background )

Titanium backup ( remove all the stupid bloatware )

Cpu control ( underclock if you dont use resource hungry apps )

My battery easily lasts a day with screen on time of 3:30 hrs on an average. I have over 75 apps installed but the phone is still buttery smooth. I know the HD screen drains the battery but with some tweaking you can really bring out the best out of this device.

[MENTION=5348849]digitalmohsin[/MENTION] : Mate, Seems you haven't used your phone at all.Just kidding.Any such stats is incomplete without screen on duration.Screen is just 4%,so i guess phone was idle for most of the time in the 2 days

How i wish i get such battery life for regular use.:D
[Sony Xperia S, Acro S, Ion] n70shan:
Hi guys I will share.my experience... If u want better battery life just use stock ics version....with any kernel....because jelly bean is superb but very bad for battery life... I m on stock deodexed ics and my phone lasts about 24 hours with atleast 3:30 to 4 hours on screen time with gaming nd music etc... And yeah greenify is a.must have app :P. Ok try to keep briightness at around 40% maximum...thats it.... Enjoy!!

The best thing for my XS and its battery life was installing new Google maps and rooting. By disabling some apps and services, using greenify I got perfect battery life. I mean 13hours till 50% with 2h23m of screen on time is really great.

I tried greenify,but didnt see any improvement.I use many chat applications like whatsapp,gtalk,wechat.If i greenify them,i never get messages.If i don't greenify, battery life is same.my friend who used donation version told chat applications behave same way in that also
[Sony Xperia S, Acro S, Ion] PLovrin:
Mediaserver usually (for me at least) shows up only when listening music or watching videos. It should be this high if you listen a lot of music.

I am really happy now with my XS. Getting good battery life.

And just a small warning. If you want to disable gtalk and hangout services, just don't. You will not receive any notifications.

Maybe you can try an app called Rescan media from playstore if your phone is rooted. The app has an option called disable media scanner,that has worked for me in many roms.You can give a try.

[Sony Xperia S, Acro S, Ion] ehabbo:
Sometimes i think overclocking the gpu when playing games drain more battery, well yeah a little than normal..

so today i had 100% and then played MC4 for like 14mins and closed it to find battery 77% then i underclocked cpu and gpu to stock, launched the game again.. damn i only played for 30mins to find my battery 30% :eek:
[Sony Xperia S, Acro S, Ion] lewis021:
Overclocking increases voltage, this means more power consumption. Don't overclock when not required. Battery temperature is also a factor.
[Sony Xperia S, Acro S, Ion] red-Tequila:
Can someone help/fix this issue,I think that the case of draininig in my xs,my screen grows every second percentage in battery menu on settings Like 9% to 60%,someone know the fix?If needeed I return to 4.1.2(actually 4.2.2 opemsec rc2) Best regards.
[Sony Xperia S, Acro S, Ion] Lunatiic:
It can mean more power consumption, but I don't think it's too much. My Xperia S is overclocked to 1.728Ghz ( applied on boot ) and I don't have any battery issues at all, it actually lasts more than I want to, because sometimes, when I'm going out for a long time, the battery is less than 50% but far from being empty, and only charge when it is 4% or less. :rolleyes:

I'm using eXistenZ v2 rom and DoomKernel v5, with "ondemand" governor and "deadline" I/O scheduler.

Screen brightness is always 50%, and 2G (Edge) or Wifi is

turned ON all the time

. Auto Sync is turned off, I do it manually once a month.

And I use the "Stamina Mode" from sony. The only background app with

Push

notifications is Whatsapp, the others are Greenified. :good:

With a extremely heavy usage, I get about 8 Hours.

With a moderated heavy usage, I get about 15 Hours.

With medium usage, I get about 30 Hours.

With light usage, I get about 3 full days.
[Sony Xperia S, Acro S, Ion] lewis021:
I think that the best you can get out of your phone's battery life. S3 chipsets suck alot of batter from what I observed. It's great that you can get 3 days in light usage, my phone never lasted that long since Ever.
[Sony Xperia S, Acro S, Ion] :
The SONY XPERIA S battery is very good. Using apps to mess with the CPU is making the battery drain faster. So, in other words you are doing it to yourself.
[Sony Xperia S, Acro S, Ion] switzerland92:
Are you serious?
[Sony Xperia S, Acro S, Ion] :
Of course not, just kidding.
[Sony Xperia S, Acro S, Ion] Lunatiic:
Yeah, I did notice a difference after overclock, but the smoothness was better :highfive:

And I observed a lot my battery consumption for about 2 weeks, and deleted some apps like Facebook, because it was being shown in the "Top 10" battery consuming apps as the Second. Then I reinstalled it as a normal user app and Greenified it. Did this to a lot of apps, and, besides decreasing the battery drain, I even got a lot of free memory, which made possible residing Xperia Home in the memory :p

I have found that removing the FourSquare application, which is installed by default, has improved my battery life by a ridiculous amount.

[Sony Xperia S, Acro S, Ion] skycamefalling:
I must say I'm impressed what Sony has done to the battery life with the JellyBean update.

I had an Acro S until May and with ICS the phone used around 4% battery per hour, even I never touched it -only because of being online and Exchange push.

Now I bought an Acro S again (because there is no better outdoor-phone on the market right now) and with JellyBean the phone takes 1% per hour, with exactly the same setup.

Battery life has dramatically improved. That's fantastic! Now Sony only needs to iron out the few bugs with camera and stuff :)
