95% of time it does. Luckily my wifi router/hotspot (I use my laptop as a portable wifi hotspot for a signal boost) are within my LOS and without any barriers except glass and they are at less than 20ft distance. I generally get 3-4 bars of wifi signal strength.

Regarding the other 5% sometimes it shows the icon greyed out and without any bars in white (highlighted) but wifi still works. Weird I know.:silly:

EDIT: Do you restart (turn off and turn on after 30 seconds) your phone after recharge?

I read it on the Android Help widget that restarting the phone may help clear up memory and shut-down unwanted processes, which should result in the phone sleeping for longer time. Hence improving the battery life.
[Sony Xperia S, Acro S, Ion] del1701:
I do restart to clear out the memory, as for my wifi icon whenever I use jd the wifi icon comes on but it's greyed out :confused: always.

Also whenever I use jd my phone stays awake, it just doesn't work on my xs like it did ibn my neo.
[Sony Xperia S, Acro S, Ion] kien:
JD made no difference for me as well. After downloading GSam battery monitor and found what was keeping my XS awake I removed com.sonyericson.android.wakeup, facebook, and lightflow. "Android system" still taking up a lot of awake time.

Gmail (email only), and email sync on, over an hours browsing, few short calls and SMS I get:

Hi, I'm planning to buy an Xperia S, but what concern me most is its battery life, can it last 2 days for normal use like Xperia Arc S?

How do I disable Fast Dormancy without root?:confused:

I've been experiencing huge battery drain lately, and my phone stays up all night. I think it's because of fast dormancy.

Fast dormancy is not that important to me as i only use 2g network so how do i disable it without root?

here is a screenshot:-

And you can look at alarmdump.txt as well.

What do i do?:eek: Please help me out with this. Thnx! :fingers-crossed:
[Sony Xperia S, Acro S, Ion] metcard:
Try keeping wifi enabled even if you aren't using it.

20% battery remaining

3h.30minutes of screen on time - with about 30 minute of streaming football over 3G.

1 hour of listening to music towards the end.

It could be better but compared to what I get when I turn wifi off I'm more than happy with by battery life. The phone (Android system - 3% battery use) sleeps normally.
[Sony Xperia S, Acro S, Ion] clinta:
Is this a software problem. I am experiencing same thing. If I disable WiFi my phone doesn't sleep normally. But when I keep it on I see that the phone stays awake lesser.
[Sony Xperia S, Acro S, Ion] Kyrius:
Well i hope Sony will get this information :) with the tweaks i've done and apps i deleted my XS manages 48 hours on quite heavy usage, usually 3 days if i don't play games as i did for the last two days.
[Sony Xperia S, Acro S, Ion] brahweiz:
ynSachi distances

So its battery life is as good as Xperia Arc S?
[Sony Xperia S, Acro S, Ion] gm007:
Yes if you are not a heavy user.
[Sony Xperia S, Acro S, Ion] Piyush Rawal:
Do i keep it connected to my WiFi router as well? or just keep it on?

I mean if it's always connected to WiFi router wouldn't that eat up lots of battery?
[Sony Xperia S, Acro S, Ion] clinta:
Just keep the wifi on. No need to keep it connected to the router
[Sony Xperia S, Acro S, Ion] brahweiz:
And heavy use means?
[Sony Xperia S, Acro S, Ion] gm007:
Playing games and browsing internet all the day.
[Sony Xperia S, Acro S, Ion] Piyush Rawal:
LOL! There is no way to stop phone from connecting to wifi router. Only thing i can do is disable wifi on router when i am not using it.
[Sony Xperia S, Acro S, Ion] gm007:
LOL or delete the settings(forget network).
[Sony Xperia S, Acro S, Ion] Gloris:
can a mod/the op maybe put a summary of the required settings at the beginning of the thread? at the moment i'm getting a maximum of around 14 hours out of my xperia s, that's if it's basically sat doing nothing all day.....3 days is like a far away dream for me.....only, i don't fancy reading through 100+ pages to find out what settigns i should be using.

p.s. the whole "leave your wifi on" thing completely does not work for me. i'm on ics and i tested this a few days ago.....same usage, same location (at work, where it's not even connected to wifi), if i have wifi off the phone lasted around 14 hours tops, if i leave wifi on it's dead within 8 or 9.
[Sony Xperia S, Acro S, Ion] gm007:
In my opinion only baseband change can improve battery standby time.

The radio signal consume lot of battery.

If we could test different BB,in flashtool flashing the BB separately is not working.
[Sony Xperia S, Acro S, Ion] Piyush Rawal:

Does anyone have any idea what those services are for and how can i minimize their battery usage?
[Sony Xperia S, Acro S, Ion] Kyrius:
@Piyush Rawal: you can safely delete fastdormancy, google maps, secureclock and device monitor

@gloris: well i unlocked bootloader and rooted my phone with stock ics kernel v11 and set max frequency to 1,2MHz. I deleted then most of the bloatware and disabled automatic synchronization. As i don't really need 3G i keep it at 2G only and therefore use wifi when i'm browsing. Screen brightness is set at 25%. But deleting bloatware and unnecessary services that keep waking the phone improves the battery the most.
[Sony Xperia S, Acro S, Ion] Oriono1:
This is a picture of some guy's battery usage on ICS

And this is my phone's battery usage

The problem is my phone awakes randomly during standby, even when I have turned off all connections. This didn't happen on GB, though I have installed the same apps as in GB and ICS

Now during standby at night (all connection off), the battery drain 1% each hour. Does anyone's phone keep awake like mine?
[Sony Xperia S, Acro S, Ion] brunodmjr:
Share this precious knowledge with us, oh master! :silly:
[Sony Xperia S, Acro S, Ion] Gloris:
exactly which apps etc should be be removing that are killing out battery life?

cos i've already underclocked to a max of 1ghz min 192, and have a screen off profile of max 384 min 192. i do leave sync on, because its my opinion that a smart phone which doesnt use thigns like auto sync etc isn't really that smart.

im actually quite surprised that no android phone has to to find a way to keep data disabled until the phone or an app or sync reuires it, then turns it on and then off again once it's done what it needed to do.

it seems like a non-smart thing to have to keep data and sync disabled....surely the smart thing would be if android could detect when network access is needed and enable/disable data as necessary?

i could have sworn that even my old nokia's did this with gprs? why are modern smart phones taking such a massive step backwards in this department?
[Sony Xperia S, Acro S, Ion] Kyrius:
look at post 1033 for my answer ... There are also a few other apps, but your probably use them if u keep auto sync on
[Sony Xperia S, Acro S, Ion] heart_of_life:
Hey guys, I'm kinda noob :P and I have a problem deleting the wake up app from system app folder, I try to do it via Root Explorer it tells me that it can't be done - read only, although I have root access, how can I delete this damned app?!
[Sony Xperia S, Acro S, Ion] Kyrius:
mount R/O button should do the trick. First pres the button and try to delete the file after.

I am noticing battery problems when phone is idle so I came here and I see you have the same problems... radio cell consumes a lot. Has anyone tried to flash only baseband of any gingerbread firm? works better? Could it cause problems?

here you see, almost no using phone but battery drops a lot
[Sony Xperia S, Acro S, Ion] heart_of_life:
Thanks man.

Recently I noticed that the battery charges very slowly when the phone is on, even with most of the apps and 3G are closed, but it charges well when the phone is off! What is that about?

anyone hast tried to flash only baseband of any gingerbread firm? I have thought about doing that but not sure if is better
[Sony Xperia S, Acro S, Ion] -Harsh-:
Which is the best stock ICS for battery life ??

I accidently flashed to .453 UK (an upgrade to .452) and it has better battery life i feel..

the phone gives an on screen time of more than 5 hrs !! and the brightness is 40%.. Immediately after flashing, i used it exactly for 2hrs and 7mins (as the battery app stats), during the entire time screen was on, wi fi was on, was listening to music, i downloaded 27 apps, set up nova launcher, and did all the syncs, downloaded games and battery dropped from 63% to 33 % over this time !!! :cyclops: I feel the screen uses much less battery in this firmware coz then i saw an 1080p movie (shutter island) and after viewing 30 mins at full brightness in MX player, it dropped by 7%..:cool: Will upload the pics tonight when i will use it the same way again..

Between any other stock firmware that has a good battery life ??:confused:
[Sony Xperia S, Acro S, Ion] -Harsh-:
Here we go !!

This is what i get outta my phone !! :silly:

5hrs + screen time, m happy with it :victory:

Has anyone figured our what keeps the phone "AWAKE" at all times ? I tried leaving WIFI on, and several other choices but the usage graph still shows a wake graph reflecting on/off/on/off/etc .
[Sony Xperia S, Acro S, Ion] red.leader87:
I don't know this for sure but I'm guessing if you keep the cpu busy it will stay awake.
[Sony Xperia S, Acro S, Ion] enrique71:
Nope, as many others have stated I turn off my data connection and auto-sync at night but yet the 'awake' graph appears up/down/up/down all night long .. looks like almost like a straight white line .. something is waking the phone up.

---------- Post added at 03:05 AM ---------- Previous post was at 03:03 AM ----------

@ Dedei - You need to go to Titanium Backup and un-freeze that app. That's the easiest way I know of how to get it back.

ps> I did the same thing and this is how I fixed it.
[Sony Xperia S, Acro S, Ion] -Harsh-:
Its a bug in the ICS that's keeping it awake. Flash to.58 generic turkey firmware, it has the least waking issues !!

[Sony Xperia S, Acro S, Ion] Felimenta97:
-16. 1.58 fw.

Ok: I got home 15 minutes ago and this is my battery for now:

As you can see in the status bar, the battery is at 55%. I will post again once the battery reaches 10%, with a usage statistic (approximated values)

[Sony Xperia S, Acro S, Ion] Felimenta97:
Finished my day a little before I expected (I'm almost asleep here) with the battery with 14%

So here are the screenshots:

So, I will say whatever I can remember:

Info:

Kernel: SSpeed 5.1 stock speed

Firmware info: 1.58 Turkey, debloated (froze Battery Saving app + Timescape at around 10 hours of usage)

WiFi time on: 6 hours

Data: Off all the time

Screen time on: 3h 40m

Music playing time: 40m~1h.

Other usage info: Played two videos (4 min + or -), took a few photos, half with fast capture mode, 4 calls (around 1 min each).

Apps on background: Juice Defender Ultimate(advanced mode, if you want my setup let me know), Battery Widget Reborn Pro and WeatherEye, as main apps.

So, this is what I managed today. This is enough for my Mondays and Wednesdays (I stay longer at school theses days, so less WiFi usage). On the other week days, the battery is enough to me until about 7 Pm, when I get home with time to charge.

If you want to ask me something, post here (if you quote me, PLEASE remove the ) or drop me a PM.

[Sony Xperia S, Acro S, Ion] -Harsh-:
Yup :) the default battery saver..
[Sony Xperia S, Acro S, Ion] reza_v:
Screen-on time: 4hours

1 hour of playing virtua tennis

Wifi was on almost all the time

If the deep sleep problem get fixed it would be one of the best smart phones,battery wise.
[Sony Xperia S, Acro S, Ion] realfelix:
I think the power saving app is a real battery drainer on the Xperia S and other phones(Acro S). I'm quite sure that with the next update we will get the same features as the P. This contains the option to show the battery percentage in the statusbar(like the iPhone or Galaxy S3) and an extended standby mode(power saving) in the Settings instead of a seperate app.
[Sony Xperia S, Acro S, Ion] gajer:
Hi guys i think this battery saver app is not useful... I did not use that... When i set up the timer for auto sync, wifi, etc. it did not work... The stop time is arrived, but auto sync is still on. I use only my hand to stop sync, put the phone to airplane mod for night.
[Sony Xperia S, Acro S, Ion] -Harsh-:
The power saver app is a pain in the ... Its was okay with gb but not with ics.. Hope it would be fixed in the update that's gonna be out in a week or so!!

Use the thank button, it's there for a reason :)
[Sony Xperia S, Acro S, Ion] Afia2k8:
Guys, I've downloaded Battery Saver app by Antutu from the Play Store. In the app, click the + sign till it's Saver level 3, then enable it. I've managed to improve my battery life to a day with heavy usage, almost 2 days with light usage.

Another thing with the app is you can set to automatic Airplane mode for a certain duration if you want (eg. when you're asleep)

[Sony Xperia S, Acro S, Ion] smallz2k:
You just will not get 24hrs on any modern up to date smart phone nowadays,with heavy use,(to me heavy use means at least,6hrs+ calls with speaker phone and whatever else msgs,music etc) espcially with such big HD screens, gone are the days. I've used Most juice saver apps,I stick with juice def. I think the most effect ways are to just use 2g and make sure everything not being used is switched off (bluetooth,backlight etc) and obviously most importantly screen off.A lot of the time I have 2phones with me and both end up dead. I think there will only be a significant difference when the actual battery development takes a leap.. :mad::cool:

I have similar battery life but achieve deep sleep. Before root I got similar activity but the battery would drain between 1-2% per hour! Now it's draining at 1% tops with WiFi on. Are you using stock .45 Rom and stock kernel? There should be an app to determine what process is keeping your device awake.

This is my battery on ka 11.1 rom and ka sspeed kernel 5.1. Experimenting with cpu governors over the next few weeks too.
[Sony Xperia S, Acro S, Ion] geekygrl:
Been stuffing around with many settings and apps in the stock Xperia ICS ROM but as a heavy user (twitter syncs 10 minutes, Kik messenger on all the time, heavy SMS/MMS user (100+ a day) camera and music, web surfing) I was lucky to get between 5-6 hours always on 3G (we have 3G everywhere and no signal issues - I have never been one to use 2G on a 3G phone :rolleyes: )

Coming from the HTC One XL that was lasting around the 10 to 12 hour mark with the same amount of activity on a really good ICS ROM - so a little disappointed in Sony in that regard.

Last night I installed CM9.1 - wow the phone can actually sleep the moment you turn the screen off (with the same apps as above running!) And its no longer a matter of losing 1 percent every 10 minutes! Will be able to get a better picture after a couple of days, but so far CM9.1 might be just what the battery doctors ordered :D
[Sony Xperia S, Acro S, Ion] itsmarc19:
what custom ROM and kernel would be the best battery efficient and at the same time, makes the Xperia S' performance better? I'm still stuck to the Stock 6.1.A.2.45 FW and ICS.
[Sony Xperia S, Acro S, Ion] jonmorris:
Since updating to 2.45, the phone is flying. There are new transitions and it's all good.. but the battery; OMG!

It's killing the battery. I can't remember what I had before I went to bed last night (maybe 40-50%) and by morning the phone had switched off.

CPU Spy is showing that the phone barely ever goes into deep sleep now. I've not changed anything since updating the firmware - so I can't see what app is suddenly causing the problem.

However, what I have noticed is that the phone is now spending loads of time at 192MHz. I don't think it ever used that speed before on my phone (it was deep sleep OR 384MHz) so what has Sony done? It's as if it's now going into standby and running at 192MHz virtually all the time.

Was it an attempt to fix the quick launch problem for the camera (if in deep sleep, it doesn't launch) or something? Because the camera still doesn't always start, and I can still get 'Memory Error' that stops the album loading (although photos still save most of the time).

Finally, any ideas when Sony plans to get the ICS firmware right? I mean, they're getting there with the speed (and reduced memory usage) but I quite fancy having the battery lasting more than 6-10 hours!
[Sony Xperia S, Acro S, Ion] inyourfacedunk:
Same boat here.

I went from getting 4 days of battery life down to barely making 2 days (I'm not a heavy user).
