This is my battery today on a typical day at home. And below is my battery whilst im at work.

Im on gb .75 ive had the phone for a week now.
[Sony Xperia S, Acro S, Ion] Velnica:
How long is your screen on for? Clearly it's sucking all of the power. Try lowering the brightness, lower the screen timeout and maybe turn off the Bravia Engine for a while. See if it improves.
[Sony Xperia S, Acro S, Ion] Pantelakos:
Hey guys got my xperia s for over a week and I love it... However battery life is a problem for me

I have advanced task killer killing apps every half an hour and brightness at mid, WiFi on. Any suggestions?
[Sony Xperia S, Acro S, Ion] del1701:
Don't use a task killer, kills the battery
[Sony Xperia S, Acro S, Ion] Pantelakos:
Ok thanks mate uninstalled :-)
[Sony Xperia S, Acro S, Ion] Pantelakos:
Is there any other way to close background running apps? Sorry if I am getting a little off topix
[Sony Xperia S, Acro S, Ion] rkanwar:
My screen is on and off due to texts coming through. My brightness is on 60% roughly and timeout is on 30 seconds but I always lock the device unless on charge
[Sony Xperia S, Acro S, Ion] K900i:
can some1 with ICS with no battery drain Issues please state their screen time instead of posting screenshots :D

My screen doesnt last longer than 3:30 minutes In ics so switched back to GB
[Sony Xperia S, Acro S, Ion] tel033:
Hi did you guys use your phones at all?? Three days is just to damn much mine with normal use I get around 15 hours and maybe 18 with 2g and not much use.. It's been a month since o got my phone and I use battery Dr saver which I think does help much but I don't Luke uh juice defender cause it kills data so I'm not able to receive whatsapp.. What your tricks? :D
[Sony Xperia S, Acro S, Ion] Pezo:
You don't need to close apps in the background, either they are designed to work in background or they don't do it (or have a bug).

Sent from the Delta Quadrant using a transwarp conduit.
[Sony Xperia S, Acro S, Ion] FenrirMX:
Yeah, normal use, maybe a little lighter than normal since it was on the weekend, and I stayed home, but still, even with this kind of use, most I could squeeze out of Gingerbread was 30-ish, and that was going into the red (under 15%).

So, I topped out at around 60 hours, then I had to charge 'cause I needed it charged for work, it still had about 19% charge to go.
[Sony Xperia S, Acro S, Ion] ahmedoxo:
ammm just a thought!!!

Are the screens with yellow tint consume more power than the not affected ones??

:confused:
[Sony Xperia S, Acro S, Ion] belek1979:
ICS with 200 apps, many widgets last for 8 hours of surfing thr opera (edge) and listing music. sometimes sms, call or some app... on GB it was maximum 4 hours so im impressed of ICS in XS
[Sony Xperia S, Acro S, Ion] realfelix:
obviously lying and trolling.
[Sony Xperia S, Acro S, Ion] noob.fl:
if you don't have root, there is no way to close them permanently, because the most apps have boot recivers... but dont care... if there are just empty aplications in the background, they will not use any batterylife... and if there are much needet apps is better to wake them up from RAM then boot them from the ground for batterylife
[Sony Xperia S, Acro S, Ion] tel033:
Really I cant get a day of it its 6 20 PM HERE AND MY BATTERY is in 18% please help I use battery Dr saver but I guess it doesn't work
[Sony Xperia S, Acro S, Ion] TheFirstFishy:
6 hours of sleep with data and Wi-Fi of and I lost 0% battery.

Got around a day of light to medium use after the first days of testing are over and start to use the phone abit more normal.
[Sony Xperia S, Acro S, Ion] Felimenta97:
This is what I managed. 2 hours of video playing, WiFi off and airplane mode on, the rest of the time, WiFi on all the time, same for screen, about 20 minutes of music on speaker plus 30 minutes on headphones.
[Sony Xperia S, Acro S, Ion] realfelix:
this is what ive managed...

4 hours of screen on.. mostly templerun or facebook and customizing the phone and a bit of watching videos..

not impressed so far.. although the battery was at 11% and did hold onto 5 hours screen on time.. but didnt make a screenshot as my battery was at 1% so i had to be fast to get to the charger :D
[Sony Xperia S, Acro S, Ion] sonic_boom:
My is also pretty bad on ICS . Basic usage brightness on minimum . Only few apps installed. My SXS may survive up to 5-6 hours .
[Sony Xperia S, Acro S, Ion] AnubisNefer:
Wow, that's terrible! On ics my phone lasts about 30 hours with autosync on ( gmail and whatsapp) and wifi.

Brightness is set to 55
[Sony Xperia S, Acro S, Ion] metcard:
For every hour that the screen is on I get about 15% battery drain at 30% brightness. There is very little drain when the screen is off and not being used.

stock .75 generic firmware. :good:
[Sony Xperia S, Acro S, Ion] bustervic:
Not impressed? Are you kidding, that is great! 5hrs of screen time is way better than guys with the OneX are getting.
[Sony Xperia S, Acro S, Ion] Korumera:
Pretty random bug :) not everbody has this problem but i'm not the only one tho :) it's sucky tho :D but still a great phone :D
[Sony Xperia S, Acro S, Ion] Ambroos:
People need to remember that the battery on most recent phones (and Sony Ericsson phones even more) needs a few days to get settled.

The first days with my Neo and Arc S I was seriously pissed off by the battery, a week later it was always perfectly fine, and did much better than any other phone brand really.
[Sony Xperia S, Acro S, Ion] Korumera:
This has nothing to do with the battery m8 :) it's a process that's keeping the phone awake not a battery that's not optimized yet.
[Sony Xperia S, Acro S, Ion] Pett0:
Hi, just need to know if I should replace my phone for new one or wait another few days to see if my battery will settle down because I have got trouble with drained battery even twice per day..Im not heavy user and battery life is around 7 hours. I have the phone for 4 days and no changes so far :confused:

Pls any advice
[Sony Xperia S, Acro S, Ion] Korumera:
Make some screenshots like i did, that will give a better picture if it's the battery or something else
[Sony Xperia S, Acro S, Ion] superlimau:
If you all have root access and tb, freeze com.sonyericsson.awake. It's the fast dormancy services which woke up phone up 200-300 times in 6 hours of sleep. LINE, FACEBOOK AND WHATSAPP are the next culprits.

Prior to freezing com.sonyericsson.awake, I lose 20% in airplane mode with WiFi on for 6hours of sleep, now I lose 5% instead.
[Sony Xperia S, Acro S, Ion] :
Hi mate, I don't have exactly this process, but I have com.sonyericson.android.wakeup, do you think it's the same one please ? ;)
[Sony Xperia S, Acro S, Ion] ssj_jaypee:
Whats the purpose of that process though?

I'm sure theres a reason its on the device. Sony wouldn't dump it in there if it drained the battery hardcore for no reason. :confused:
[Sony Xperia S, Acro S, Ion] :
The fast dormancy process is all about fast switching between 3G and HSPDA networks, but it's also known as a great battery drainer sometimes ^^'

Sent with my Xperia S
[Sony Xperia S, Acro S, Ion] ssj_jaypee:
What will happen if I disable it?
[Sony Xperia S, Acro S, Ion] :
Honestly, quite nothing, the switching process will just be a bit slower.

Sent with my Xperia S
[Sony Xperia S, Acro S, Ion] ssj_jaypee:
Okay I'll give it a try later, thanks!
[Sony Xperia S, Acro S, Ion] superlimau:
yes yes, that was the one... i just woke up moments ago when i was typing and made the error...:D
[Sony Xperia S, Acro S, Ion] deanfield:
I was just wondering, if I root the phone, can I still be able to upgrade to ICS officially?
[Sony Xperia S, Acro S, Ion] superlimau:
that i dont know, since my arc days... my BL was unlocked < 10days of owning the phone... :P
[Sony Xperia S, Acro S, Ion] Cholek3:
Yes, after unlocking bootloader you can still upgrade official way.

[Sony Xperia S, Acro S, Ion] mmonkiee:
Guys there is an update for the xperia S, install it through PC companion software in you PC. I cant find it with my phone's update app.

Just installed, going to see if it improves battery life.
[Sony Xperia S, Acro S, Ion] FiDra:
Can you show the build number of your update?

We are currently on .67 firmware build.

Thanks!
[Sony Xperia S, Acro S, Ion] doministry:
No, some are on. 62
[Sony Xperia S, Acro S, Ion] FiDra:
Sorry :D

I meant we are already updated to to .67 (but some are not)
[Sony Xperia S, Acro S, Ion] K900i:
and we are struggling fr a 4 hr battery life :(
[Sony Xperia S, Acro S, Ion] Damoedge:
Try letting the battery drain completely best do it at night time then charge the phone over night, phone turned off.

I think ics learns the battery charge/discharge cycle and adjusts for better performance.

Give it a try ;)
[Sony Xperia S, Acro S, Ion] Velnica:
Okay, here's my typical usage of late. I'm working from home so most of the time I only use my phone to browse the net while sitting in bed or the lounge. Screen time around 2 and a half hours. Wifi and 3g on at all times.
[Sony Xperia S, Acro S, Ion] Elixx13:
Guys I can't manage my battery to stand up for more than 6 hours, while moderate-hard-very hard use. Updated to ICS, in the first charge cycle (Phone Arrived, charged 3 hours until 100%, updated & rooted). And I guess it's Running pretty "well".. It has some minor bugs but its 2nd time I re-flash Generic ICS... Well that's the main problem. I do wait until phone gets off before re-charging and sometimes I charge the phone while its On... I only have like 5 days with it and the battery seems to be better day by day.. Note: While the phone its in stand-by, I mean using the phone for calling, whatsapp. some little browsing... It just last forever.. I can get almost 22hr. But when i watch videos, listen to music, play a lot, download, tweak, customize.. It just drain so freaking fast. Any Advice?:rolleyes:
[Sony Xperia S, Acro S, Ion] FenrirMX:
I honestly don't give a rat's ass if you believe me or not. That's the way it happened. Period.
[Sony Xperia S, Acro S, Ion] Velnica:
The screen will be your biggest battery drain. Using it to call, message, etc doesn't turn on the screen for as long/as much as watching video, gaming, tweaking etc.

Check your battery stats and if the biggest user is the screen, there's nothing more you can do. Feel free to check other phones as well, at least this one is LCD and not AMOLED, because the latter is an even bigger battery drain.
[Sony Xperia S, Acro S, Ion] system02:
I believe that there must be some kind of defect in the batteries or the Xperia S hardware!

I had 5(!) Xperia S phones and tested them with the exactly same configuration (no additional apps installed) and same firmware (.75) and they had big differences:

- 2 of them drained the battery in approx. 10 hours of standby

- 3 drained their battery between 20 and 30 hours.

Why didn't I keep one if them? Because none was free of faults. Awful battery, noises during phone calls, complete yellowish display... it could be such a wonderful device. :-(
[Sony Xperia S, Acro S, Ion] wernerzero:
Must say I have the complete opposite experience. About 60-70hrs on normal use with GB and now 18-24 hrs with ICS... :(

W.Z.
[Sony Xperia S, Acro S, Ion] TheFirstFishy:
Go back to GB if you dont like the battery usage in ICS, and wait for Sony to fix the problem.

I tend to sleep every day, and while i sleep the phone charges. And since my charger is so small it can fit into my pocket, i can grab it along if i know im gomma be away for a few days. No need to have 40+ hours of battery when they put a charger in my box and im allowed to use it.
[Sony Xperia S, Acro S, Ion] realfelix:
well.. i've managed almost 6 hours of screen on time with my old arc.. i know there are much less pixels to render on the arc but still.. the screen aint much bigger on the S ..

I cant just use my SXS as a heavy or average smartphone user, i just have to save my battery all the time . i dont like it ,
[Sony Xperia S, Acro S, Ion] tel033:
I'm sorry but that just seems impossible do you use your phone? 60 hrs on GB IS A LOT I get 16 hours top and even in Ics with 24 I will be mote than happy.. How did you charge y pour battery the first time? Any other tip?
[Sony Xperia S, Acro S, Ion] joshua_sx1:
Screen is really the big factor in draining battery... I guess that is the consequences of having an excellent pixelated LCD screen with duo-processors and having not enough battery specs... the only solution for this is to change the Xperia S battery to a bigger capacity... if Sony will do this, I'm willing to pay additional for a better battery memory capacity...
[Sony Xperia S, Acro S, Ion] noob.fl:
hihi... Smartphones with small batterys are a very good education tool to teach people about sustainabillity and managed limited resources... if we use, what we learn with smartphones, in the whole world - i think, the world can be a better place

so, my 2 cents about batterydrain on saturday morning :angel:
[Sony Xperia S, Acro S, Ion] SnowOokami:
I think the only smartphone with a long battery duration is the Motorola RAZR MAXX :laugh: all other smartphones suck with battery life...

the HTC One X will empty after 45 mins of gaming (100% to 0%...) kinda sick :silly:

average battery drain here is 5% /hour
[Sony Xperia S, Acro S, Ion] belek1979:
no way to make a bigger capacity in the same size of the battery... in htc hd2 I had bigger battery then a stock one, with a extended battery cover. looks awful and big but sometimes it was gr8. but mostly I used stock battery and external battery bank... like i do with XS
[Sony Xperia S, Acro S, Ion] K900i:
which region ICS are yu using?
[Sony Xperia S, Acro S, Ion] lparasca:
Actually, I don't think it's impossible... mine still has GB and on it, and usually, with some browsing, 15-20 minutes calls a day, e-mail and Facebook manually synchronized a few times a day (whenever I want to check them), I get about 2 days battery lifetime. The display and Cell Standby were sometimes on par in terms of battery usage, sometimes Cell Standby would exceed the display. A few days ago I changed the network mode to WDCMA only and I had a really nice surprize: after one hour calls, and the usual browsing, e-mail and facebook and 1 hour of music, the battery was at 70% at the end of the day (fully charged in the morning). I usually keep wi-fi, bluetooth and background data traffic off. Display is at 20% (enough for me most of the time). With these settings, the battery drain while on standby (during the night, when I sleep) is around 1% per hour.

Personally, I really am disapointed with this new trend of powerfull but battery lifeless devices. It just contradicts the idea of mobility... what's the point of making a MOBILE device if you need to keep it plugged in? Just to move it from one power outlet to another?
[Sony Xperia S, Acro S, Ion] nanoxy:
Hi, I still have (in my opinion) poor battery life. Not bad but not nearly as good as some ppl around. I have the phone for 4 weeks now, but battery life seems to become less instead of more (about 16h if I'm lucky, which is not bad, but it has been better, and it CAN be better).

So I read that free apps could possibly drain battery in terms of constant wifi activity or something (is this true?), so my question: is there an app or something which shows you what apps are active during the day and how much activity that is? Because I think apps are running in the background without me knowing it.

Also, I read about AdFree Android, does this app increase battery life? Does it also decrease activity of apps that are not used?

In the beginning without wifi on, battery drain was about 1% per hour, and with wifi some more. But atm with wifi on battery drain is 5%... which is insane, going from 100% to 65% in one night without activity.

And could a battery reset help? I read something about it, but cant find it anymore.

I have the .73 update (it was pre-installed), 40% brightness, no auto-sync, no bravia engine.
[Sony Xperia S, Acro S, Ion] noob.fl:
that has nothing (or not much) to do with apps... but if you use WIFI, its clear you need more Battery, because you able a datamodule thats running and runnig, scanning, upload, download, will hold connection, rescann every 15 seconds - i mean, dont use your Moden/Lan/whatever adapter at home no fuse? :confused:
[Sony Xperia S, Acro S, Ion] nanoxy:
What do you mean with the last sentence "no fuse"?

Hm I believe before I installed some apps even with wifi on the battery drained more slowly, so it would be handy if I'm in some way able to check if there are apps that increase wifi activity...
[Sony Xperia S, Acro S, Ion] wernerzero:
Can't remember all the "tweaks" anymore, but I'll try to write down some as well as my normal usage.

Mail, calendar, facebook etc. syncs/ 1 hr,

screen brightness 25%,

Bravia On,

XPS launcher,

GO lockscreen,

wifi off at night,

no bluetooth (don't need it),

calendar and weather widgets only,

gps on (maps/navigon "wakes" it when needed),

"original" facebook app (fbm and friendcaster drained battery fast),

charged when batt 15-20% and "always" to 100%.

One day of normal use would be 5-10 calls (calls are easy on the battery),

checking and answering mails 5-10 times,

Endomondo 1-2 hrs tracking (amazingly easy on the batt, 1-3%),

navigation 1-2hrs (screen not always on),

gaming 1 hrs,

reading feeds (Feedly) 1 hrs,

taking about 10 photos and 1 video,

using Dropbox, Evernote and calendar a lot,

occasional browsing, youtube...

Guess that would make about 4-5 hrs screen-on time.

Well, that's about it...as far as I can remember.

Tried to tweak the ICS the same way but only one third -halfway so far. Have to admit it has improved slightly...

W.Z.
[Sony Xperia S, Acro S, Ion] tel033:
Thanks I have basically the same configurations GPS Bluetooth WiFi off data 3g on sometimes 2g auto sync only fb 4 hours and twitter 2 whatsapp and twitter via push feeds about 30 minutes per day and a maybe 45 gaming and thats it and I get 16 hours :confused:
[Sony Xperia S, Acro S, Ion] wernerzero:
Yeah, that's so crazy with these androids...they are all individuals...never know what you get and what settings will work for you. :confused:

I've seen that what I got out of GB, someone else now gets out of ICS, while mine sucks now on ICS and vice versa. And not only in battery lifes, but in other aspects as well...

And this isn't just an XPS problem. Same with all brands and models... :(

W.Z.
[Sony Xperia S, Acro S, Ion] naughtb4:
With ICS im finding that Media Server, Android Systemand Wakelock are the main culprits to my decreasing battery life.

Iv gone from two days to a day, seriously thinking of regressing to GB.

for those with decent battery life are the above three processes still takng alot of juice?
[Sony Xperia S, Acro S, Ion] 18lama:
Battery life with Data on, auto sync off wifi off
[Sony Xperia S, Acro S, Ion] naughtb4:
In addition mine also now takes an age to charge.

Sony have messed up this update IMHO
[Sony Xperia S, Acro S, Ion] realfelix:
it's a pain in the ass but turn off data and wifi while charging, it will go faster ;)
[Sony Xperia S, Acro S, Ion] Sikiduck:
The battery really sucks in ICS.

When I went to bed last night, I turned on power saving app and flightmode. The battery went from 55% to 8% in just 45minutes!!!

WTF is wrong?

Force GPU-rendering or what its called was on, but I cannot believe that was the cause of fast draining. In GB I only lost about 2-3% over night with powersaving profile and flightmode! ://

Edit: it also takes ages to charge as well.. In GB, 40minutes charging I would have about 40-45% battery, in ICS I only got 30%.. Jeez!
[Sony Xperia S, Acro S, Ion] s-X-s:
How about the network mode in ICS ( wcdma preferred/gsm was the main cause of battery drain even in standby on sony Gingerbread- selecting either one lasted my battery 2 days) .. is it still same- WCDMA preferred/GSM mode causing battery drain ( it keeping switching between casuing battery drain in GB) in ICS also... i cant tell myself coz my screen is customized with lot of widgets and display using 70% battery.... still it lasting for 24 hrs with mornal usage with no gaming.....
[Sony Xperia S, Acro S, Ion] haymant:
just bought last night, didn't test consumption at sleep time.

here is the usage in last 8 hours.

feel pretty good comparing with iphone4, is it?

22% left.

was reading/installing and surfing at the first 3.5 hours, without screen off.
[Sony Xperia S, Acro S, Ion] tel033:
Can anyone recommend me a good battery saver app? Other than juice defender cause that doesn't allow data when screen in off so I can't receive whatsapp messages

This is so weird guys. Im on gb stock etc etc but the weird thing today I decided ill use my old arc s ep800 charger and the usb cable from my x10 with wifi on from 56% my battery has been boosted to full. I put it on charge 25 mins ago. Could this be the usb cable? Because I have the exact same one that I use on my xs as the one that came with this phone is too short and not even that cable has this effect. Or could it be the actual plug?
[Sony Xperia S, Acro S, Ion] TheFirstFishy:
Yes, i dont use the ics power save.

But with flight mode turned on, i only lose around 0-3% battery during sleep (6-8h)
[Sony Xperia S, Acro S, Ion] prask9:
My only problem is, battery drains super fast when Wifi is on. In other cases battery is great.

Anyone else facing the same problem?
[Sony Xperia S, Acro S, Ion] belek1979:
all this thread is pointless until you use CLEAN new ROM.

if you have 10, 50 or 100 apps then you will never know what cause the problem with fast battery drain. some of these apps are bad for GB soma are for ICS. for example few first versions of Official Euro2012 app drained my battery to 0% in 4 hours. but the same versions were damn good on ICS. everything depends on app optimization. sometimes it is a configuration of apps. so don't write stupid posts what to do for battery. first do a hard reset. if you don't like that then choose iOS. fragmentation of Android is so huge that there is no way that apps will work perfectly oin all devices. YOU HAVE TO CHECK APPS NOT HARDWARE OR FIRMWARE!
