Had my beautiful white S for 24 hours now. Overall very positive, except battery life so far. Drained 23 % overnight from a 100% charge. In only 7 hours :( I had NO activity. BT and WiFi on.

I hope this will improve very soon. That is a no go. Would like to hear from you about your experience regarding your new Xperia S.
[Sony Xperia S, Acro S, Ion] Rashkae:
For me, I removed junk I don't use, like foursquare. That alone made a huge difference. I also turn off data at night, and only went down about 4% while I slept.

Another option is to install something like JuiceDefender, which automatically shuts down data except switching it on every hour or so to allow for some syncs, then shuts it down again.
[Sony Xperia S, Acro S, Ion] Mesho Arc:
same as my arc, drained about 30% in the first day, with time it'll be better.
[Sony Xperia S, Acro S, Ion] malimal:
i was about to ask the same question. 7 hours seems about right, but i have been doing a lot of app installs, so I will give it time to settle down.
[Sony Xperia S, Acro S, Ion] jcsmart:
I use the XS in Hong Kong. If I use the phone online to play with internet browser, battery will be drained from 100% to 69% in approx. 1 hour. Is it too fast? Or it just a normal way when compare with SII or GN?
[Sony Xperia S, Acro S, Ion] Rashkae:
The display sucks battery life like a vampire in a young virgin woman buffet. Try reducing the brightness.

Hopefully firmware updates will help there.
[Sony Xperia S, Acro S, Ion] Lasse3040:
Ohh yes. U are soo right. Had my phone now for 4 days. The display uses an average of 70% of the overall battery consumption. It is not WiFi, calls, BT or any other functions. It is the display that drains. Will give it the weekend to see if it improves. If not I will return it on Monday :-( And my brightness is down on less than 25% so not much to do there.
[Sony Xperia S, Acro S, Ion] dibdin:
I get about the same on my Arc. I dont know if it's too fast or not, but if your pretty much constant on the net for an hour say then 69% isn't all that bad.
[Sony Xperia S, Acro S, Ion] Lasse3040:
Had an Arc for around one year. On a daily average the screen took about 55% and I had no problems to get a full day out of it. (approx 16 to 18 hours) and still 10-15% juice left. Now I get max 10-12 hours out of my S and NO juice left. Really disappointing. Even my old X10 did better than my new S.
[Sony Xperia S, Acro S, Ion] dibdin:
Surely the HD display amongst other things, ie how you have your phone set up, may go someway to why your experiencing poor battery life compared to your Arc.
[Sony Xperia S, Acro S, Ion] gbil:
Try to disable Bravia engine and see if you notice any difference especially during the night.
[Sony Xperia S, Acro S, Ion] doministry:
My phone has the same apps as my Arc, actually minus few of them.

No autosync etc.

Basically it drains the battery quick, it's unacceptable. It behaves exactly like one of the older Arc firmwares, which was also draining battery like crazy.

Than they fixed it and it's still brilliant. My Arc on Flight Mode beeing just a backup in case of any problems, runs 3rd day on one charge, still 75% left.

I think S is just not optimized and it makes me mad.
[Sony Xperia S, Acro S, Ion] dragon546:
Just got My XS yesterday I did one fully charge this morning . Turned off data at home, will not know until battery is fully charged by a few cycles. I love the phone irrespective of the flaws. I think may be see in a week or 2 where my battery settles.
[Sony Xperia S, Acro S, Ion] Lasse3040:
Again. 25% battery drain in only 6 hours over night. No physical activity at all. This baby goes back on Monday :-(
[Sony Xperia S, Acro S, Ion] keunhuvac:
3g turn on with weather widget in background only, 4% drain overnight, but with heavy usage (game, internet suffering...) it lasts about 7 hours, that's good.
[Sony Xperia S, Acro S, Ion] FiDra:
You can use Profile Scheduler (free from market) and set a schedule.

I've set the schedule in which the airplane mode will be activated at 12.00 am and turned back to normal at 6.00 am.

By this way, my phone battery drains overnight just only 2-4%.

Let's try man :)
[Sony Xperia S, Acro S, Ion] awf:
Or use the supplied power widget B-)

[Sony Xperia S, Acro S, Ion] eddyedwards007:
Do you know what? It irritates me reading you people moaning about battery life, it's a high definition phone with an awesome screen, if you want your battery to last a few days, go get a cheap phone that does nothing but txt and calls:mad:
[Sony Xperia S, Acro S, Ion] GalaxyS2R:
I actually agree with that tbh, and another thing is battery life all depends on how the individual uses their phone.

I had the sgs2 and alot of people said oh the battery life is rubbish but yet they had:

screen brightness on 100%

3g, wi-fi, bluetooth always on

live wallpapers running.

Plus they were using the internet for like 2hours

sending numerous emails

playing games

listening to music

I mean come on its a phone at the end of the day, its not a super computer or something or some nuclear powered device.

I nearly 2 days out of my sgs2 under moderate - quite heavy usage

because I turned my screen brightness all the way down

didnt leave 3g, wi-fi, bluetooth on all the time only when i needed to use those features, i never used live wallpapers and i dont send numerous emails.

when i had the play again people said the battery life was rubbish but again i got about 1day 10hours or a bit more sometimes based on the above mentioned info.

so as long as my SXS last 1day even I dont mind that because at the end of the day it has a HD screen so its going to use alot of power.
[Sony Xperia S, Acro S, Ion] shmoejoe:
Okay so on my third day with the phone...

my battery is fine, actually...more than fine. I turn off my wi-fi/bluetooth/gps when not needed, and I don't run my battery heavy apps for a long time.

I also installed a task killer...I know it's in theory not needed, but I will see how it goes.

woke up around 7 today, used my wifi, used a battery intensive app (dream zoo :D, it's an addiction) for like 15min or so. Went for a walk, used the camera...a LOT, made a lot of panorama pictures. It's now almost 11:15 and i'm only down less than 15% I believe.

It's got much better battery usage than my X10 to be honest...but this is a high-end full HD phone, I wasn't expecting my battery to last so well D:

I will update again at the end of the day about how low it got, but I am pleased with it.
[Sony Xperia S, Acro S, Ion] thalas:
here,

Wifi connected, no auto syn, standby for 7 hr --> battery reduce from 100% to 78%
[Sony Xperia S, Acro S, Ion] WhiteHartMart:
It's the one area that disappoints me about XPS - have charged mine about 4 or 5 times so tried to conduct a bit of a test yesterday.

XPS and my iPhone 4s fully charged in the morning and taken out for the day. Both phones left with just Data on (iPhone had Bluetooth on also an was connected to car for about 2 hours).

While out the iPhone was used on 3G for about 10 mins. Both phones then used for 3 or 4 pics.

In the evening both phones used back on WiFi for about 30 mins for some forum browsing ;)

Now this morning I get up and XPS is on 17% and the Low Power Saver has been activated. The iPhone is still on 43% and is being used to type this post.

Really hope the ICS update improves this - if the battery situation got better I can see the XPS being my daily phone :)
[Sony Xperia S, Acro S, Ion] iamelton:
its a bit difficult to compared a 4.3" screen-sized device to a 3.5" screen-sized device in terms of battery consumption..

u do have to pay for the larger/clearer display somehow.. ;)

anyway i do agree that this phone's battery consumption really needs to be improved..
[Sony Xperia S, Acro S, Ion] WhiteHartMart:
Agreed but when 90% of the time the displays were off I'm not sure that's relevant :P
[Sony Xperia S, Acro S, Ion] keunhuvac:
Maybe reduce CPU frequency will improve battery life! I used set cpu tu set to conservative and max frequency=1180 MhZ, no issue at all!

Quardrant reduce too! 2670!
[Sony Xperia S, Acro S, Ion] gm007:
I am sure that the drain come from data and sync.

you can use cpu spy to track the cpu activity.my phone has been in deep sleep 7hours while the battery drop from 100 to 89 at night.
[Sony Xperia S, Acro S, Ion] andoridkiller:
I would do that, but I find It defeats the point of spending so much as one the main selling points for this phone is the speed, otherwise I could jsut get the Xperia withthe 1Ghz dual core processir with very similar specs.
[Sony Xperia S, Acro S, Ion] globalzorian:
I'm also a proud owner of Xperia S and finding its battery life annoying, too! :(

Hopefully, the imminent ICS update would fix it then and for ever! :D
[Sony Xperia S, Acro S, Ion] somemadcaaant:
This should be of use, it's not really calibrating the battery but more so obtaining extra juice if it's there and if so telling Android to account for that when charging, once we have clockworkmod or other bootloader.

The LGO2x also had battery wipe in the LG stock bootloader.

BTW I feel battery life became better and more stable.

1% in the night, 7,5 hours, flight mode on.
[Sony Xperia S, Acro S, Ion] ash_c64:
Hi can someone tell me what the Bravia engine actually does?

Does it enchance video, pictures just for viewing purposes on the device which are from external soucres or does it give better quality when recording or taking pictures with the device itself? I curently have it turned off as it seems to help save battery. Having it on or off i dont really see any difference to be honest.
[Sony Xperia S, Acro S, Ion] Ambroos:
The ONLY thing Bravia Engine does is change how images and video look ONLY when using the standard Gallery app. Turning Bravia Engine on only increases the load when viewing things in the standard Gallery.

If you don't or almost don't view photos or videos in the standard gallery app, the Bravia Engine setting will not make any difference when it comes to battery life.
[Sony Xperia S, Acro S, Ion] eugenius8:
1st time leaving it on power saving mode whilst asleep 99 > 92% (7.5 hrs)

2nd time leaving it on power saving mode whilst alseep 99 > 71% (10.5 hrs)

O.O

whenever i plug my charger into the phone, the coonector physically feels a bit loose, it'll easily wiggle up and down but it still charges, is this the same for everyone else?
[Sony Xperia S, Acro S, Ion] doministry:
Hmm no, charger input is very tight here.
[Sony Xperia S, Acro S, Ion] Gyrael:
mine's the same. If it's plugged to the charger and I use the phone, the charging is intermittent. It's not happening when I plug the USB cable to the laptop though.
[Sony Xperia S, Acro S, Ion] eugenius8:
no i meant the actual physical part of the connector :p
[Sony Xperia S, Acro S, Ion] pauloton:
Here after full charge disconnected all night it goes from 100% to 75% in 6 hours with no wifi and data traffic.

I think the battery usage really changes after some time.

Today it's 2 weeks since I got it definitely the battery life is much better!

It doesn't seem to drain so much juice anymore.

It also loads faster.
[Sony Xperia S, Acro S, Ion] saqaw:
In normal/average use How does the battery life compare to SGS2?...Is it better or the same?

[Sony Xperia S, Acro S, Ion] sephstyler:
Quick input from me, got my XS on Friday last week.

Yesterday was my 3rd full charge and today the 4th.

I have 3 push email accounts (2 Gmail, 1 exchange), and receive about 80 emails a day. Also have whatsapp working.

Both yesterday and today I disconnected at 8:00 am.

Yesterday my battery was reading 45% at the end of the workday (5:30ish) and lasted well into the evening. Ran down to 10% at about 11pm. I also had a 1 hour phone call during the day. total screen on time is 1hour 48min

Today, I've been using the phone a bit more, and am off site which means: 1. I'm using the phone with the screen on more to type emails, and have slighly worse reception today (3bars all day). Its 4:30 and its at 40%

This is rather on par with my HTC Sensation XE (last phone i had before this).

Decent, but for heavy users, get a portable charger or a car charger if you are in the car a lot.

Will report back after a full week (3 more days).
[Sony Xperia S, Acro S, Ion] christonabike:
The idle drain is just incredible. Last night I went to bed with around 30% battery and was woken up at 6:30 by the phone shutting down.

I don't have anything syncing in the background, it's just the radios.

The voice calls in the attached pics amount to just 51 minutes. Apart from that, the phone had little use.

Back to the Nexus S for the time being :(

edit: this is the 5th or 6th charge from 100% to zero
[Sony Xperia S, Acro S, Ion] eddyedwards007:
If your phone wakes you up switching off, you must be a light sleeper :D
[Sony Xperia S, Acro S, Ion] somemadcaaant:
I'm betting you installed an app or two between those two charges or had an app running in the background.

Edit:

Study says free Android apps can zap your battery life

-smc
[Sony Xperia S, Acro S, Ion] doministry:
As above, it must be the app which screws your phone.

My phone drains in the night, with Flight Mode just 1% through 7 hours, seriously.

Besides that, apparently constant charging to 100% and discharging to 0 doesn't help but rather distracts it. Let it just work, charge when you want etc.

In my case I did it just once or twice and than let the phone and battery work.

Even on a laptop, if you make a battery format you do it once, not several times, otherwise you damage the battery.
[Sony Xperia S, Acro S, Ion] christonabike:
I had no choice but to discharge 100% > zero, I've had to charge it every night and it's always died before the end of the day :(

Similar to you, flight mode drains the battery at a very slow rate. It just seems to be the radios that suck the juice.

haha yeah, it was on the table by my bed, on silent. Unfortunately it vibrates as it shuts down, right next to my head!
[Sony Xperia S, Acro S, Ion] Rashkae:
Just freeze the one process. Did all the difference for me.

com.sonyericsson.android.wakeup
[Sony Xperia S, Acro S, Ion] christonabike:
Thanks, I'll give it a go. I've rooted the phone and removed a lot of apps but I think that one is still active.
[Sony Xperia S, Acro S, Ion] Dianish:
Grrr...

I have had the phone charged to 100% ofc, and it drains 35 % each night while idle. I never let the battery run to 0, prefer to charge when the 5% warning pops up.

I had only out of box apps preinstalled and uninstalled those which i dont need. Never bothered to get new apps since im happy with the firmware.

I dont use the web(if i do i use my own wifi in house), so no data or wifi activated.

I simply use the phone for music(head phones that came in the box) and sometimes random calls and texts which never exceed 5 mins of my average day use.

Rest of the time the phone is just laying on the table in idle. I charged it around 10 times so far and only a slight improvement have been noticable. Battery have been testet and its all good.

I have freezed the com.sonyericsson.android.wakeup, and havent noticed any different. Only difference i've noticed is the bightness i've turned down to 20% - Which wont matter since its in idle 98% of the time. This is based on when im at home and not using the phone. In the battery info it shows that "Android System" is the sinner here.. I havent been able to figure out why. I have done what you guys recommended, and still no difference.

Im use to having Xperia Neo and always lastet about 6-7 days before i had to charge it - Which i had lots of games and widgets installed to personalize the phone.

I dont root my phone and never will. Dont wanna play "god of phones" :)

Guys any idea if there or there would be extnded/bigger rating batteries released for this set, as the battery can be replaced by opening the screws in the back, bigger batterries would be great..
[Sony Xperia S, Acro S, Ion] zeph_syk:
There might be some 3rd party vendors working on this as it is too early to release a compatible battery, mind you AFAIK removing the back cover may void warranty..
[Sony Xperia S, Acro S, Ion] yachtman:
I'm so disappointed with the battery life too. I'm using it for 8 hours now (28% left), with very light use (facebook, email). Is this normal? Should I exchange for a new phone?

I've also lowered brightness and disable bravia engine but what's the point of having a phone and not be able to use it for the full capacity.
[Sony Xperia S, Acro S, Ion] Felimenta97:
For everyone that is complaining about the life:

Wait at least 2 weeks before it settle down. It may be less time, but give it 2 weeks.

When I bought my Xperia X10 MP, the battery couldn't last 1 hour. But, after 2 weeks, I settle down and could run for a day.

it will get better over time, and with the next update it will even get better.
[Sony Xperia S, Acro S, Ion] ash_c64:
The phone has the same firmware but it seems the second one is from a different batch as the box was abit different and came with the better Smart Live Sound Headset.
[Sony Xperia S, Acro S, Ion] Xadious:
I've found that if i select a specific network mode, as in GSM or WCDMA rather than automatic dual mode (Wireless Networks --> Mobile settings --> Network mode), then the battery lasts MUCH longer. I left the phone in WCDMA mode overnight, checked it after 12 hours and the battery drained only 6% instead of the 40% it drained prior. Add to that, if i left it on GSM it might drain even less as 3G is supposed to use up more power right?

Obviously this isn't a fix as you want the phone to be able to switch modes automatically depending on your location, but it does suggest it's a problem with the switching from 2G to 3G that's causing the battery drain in idle mode.

As mentioned a few pages page, it probably has something to do with com.sonyericsson.android.wakeup
[Sony Xperia S, Acro S, Ion] gurubumsmack:
I'll give that a go and force it to GSM mode and see what effect it has. The slower data speeds won't hurt me too much. Should be fine for receiving emails. I tend to do a lot of browsing on WiFi anyway.

I wonder if the people reporting decent battery life are those in strong 3G areas? In that scenario, the Xperia will stay on that network mode.

However, if you are in a 2G/3G borderline area, the phone will attempt to switch to 3G then fall back to 2G because the 3G signal strength is weak, rise and repeat?

I'll see what the battery drain is like overnight. If is better, I'll leave it on GSM mode until Sony pull their finger out and release a fix.
[Sony Xperia S, Acro S, Ion] Gyrael:
this is the problem with my XPS, the 3g signal varies in my location so I just leave it in GSM and the battery last longer than before even if I have wifi and bluetooth enabled all day :)
[Sony Xperia S, Acro S, Ion] ssj_jaypee:
trying only WCDMA mode tonight and seeing if battery life improves.
[Sony Xperia S, Acro S, Ion] emwgee:
I saw a post in a Chinese forum saying that the Xperia S battery needs to be "activated" before reaching full capacity, and once activated it also resolves the high battery drain problem everybody is complaining.

I followed the instructions given and my battery capacity had actually changed from 1697500 to 1750000 afterward.

Whoever is adventurous enough and wanted to give it a try can follow these steps, but please do not hold me responsible for any unusual things happening to your phone if you try:

1. first check your battery capacity by dialling *#*#7378423#*#*

2. select Service Test then Battery Health Test, you will see Actual Battery (uAh) and a number, mine was 1697500 before I perform the remaining steps.

3. hold volume up button and power button simultaneously and wait for 3 consecutive vibrations from the phone. The phone should shut itself down and power off.

4. Power the phone back on. Dial *#*#7378423#*#* and check the battery capacity again. It should now reporting as 1750000.

5. Charge your phone.

I am now charging my phone, and still waiting to see if it actually resolves the high draining problems when the phone is idle.
[Sony Xperia S, Acro S, Ion] Dianish:
In my area there is no 3G. Only using WCDMA prefered or in some cases GSM.
[Sony Xperia S, Acro S, Ion] gurubumsmack:
After forcing GSM mode and leaving phone by my bedside overnight (8 hours), battery dropped from 100% fully charged to 94%. Better than the 100% to 85% drop in 6 overnight hours I was getting before.

I'll probably leave it like this now and flick it back to dual mode in a couple of weeks time to see if the battery has improved, as people in here have suggested.

If its still no better, I'll keep it on GSM mode until:

1. Sony release a fix

2. The fine people on here develop and release a lovely custom rom with the majority of the Sony default apps removed :D

[Sony Xperia S, Acro S, Ion] Kefakum:
Hello!

I've seen people writing that your can feeze the com.sonyericsson.android.wakeup.

Or will the process stay shut off if I force close it? My phone is not rooted..

[Sony Xperia S, Acro S, Ion] somemadcaaant:
My actual batt uAh was already set at 1750000 it seems, could explain why my battery lasts a good day.
