I'm just about speechless...this phone is not liking the ICS...

On monday night I decided to try once more to factory reset and repair-install ICS again thru SUS. All went well and on tuesday the phone was great, no lag and battery lasted for 36 hrs. I could live with that...

BUT yesterday it was laggy again and battery drain was just insane! It went from 100% to 17% in 2hrs!!! Okay the screen was on almost all that time as I was mailing and using FB, but that's really nothing "heavy"... Today it went fom 100% to 28% in 7 1/2 hrs, that includes about 1 1/2 hrs screen time, as follows, 4 short phone calls, little FBooking, some Coloris gaming, 15 minutes websurfing and reviewing photos in the album for 30 mins.

This is the worst battery performance ever in a phone...and I've had the N900!!

Seems like the only way is down...grading...

The screen is a massive battery drain (even when set dim), having the screen on and going online uses 1% every 1-2 minutes.
[Sony Xperia S, Acro S, Ion] metcard:

Disabling contacts gives too many problems.

:silly:

***EDIIT**

I had wifi switched on all day but was using the 3G network.

Push notifications on 1 app and weather updates every hour.

Hey, how to disable contacts.
[Sony Xperia S, Acro S, Ion] metcard:
Settings > Apps > ALL > Scroll to Contacts and tap on it > Tap on disable.

Looks pretty good to me. Sleeping like a baby.

I also set the background process limit to Standard limit under developer options (default).

Wifi is kept on all the time but I'm using 3G data for most of the day.
[Sony Xperia S, Acro S, Ion] darkzeuspcm:
When disable Contacts, I can't make a new contact
[Sony Xperia S, Acro S, Ion] metcard:
heh... you are correct. That's kinda weird.

It's easy enough to enable if disabling causes you more grief than before.

my alarmmanager is being an ass again anyway.

I think I will just wait for Sony to patch it up, hopefully.
[Sony Xperia S, Acro S, Ion] mrhizzo:
Any news?

I updated my Xperia S to ICS 4.0.4 and is sad! My GS2 with 1650 mah battery do more.

I didn´t think there would be much difference...

The duration will be improve in the next update?

Epic battery life with ics :) so happy... Charging in the end since I didn't know how to screenshot so had to turn phone back on to take screenshots

Anyhoo for some reason the "Android System" is draining too much battery and my phone is mostly awake for some reason... Any ideas or help?
[Sony Xperia S, Acro S, Ion] Mysteryos:
Alarm Manager is one of the most battery draining apps when your phone is idle, since it keeps waking up the CPU.

If you can avoid it, don't set alarms on your xperia s. My idle battery drain went to 1% or less per hour after i disabled alarm manager.
[Sony Xperia S, Acro S, Ion] LilChinchster:
I haven't used any alarms for sometime now and still android system uses roughly 20-30%
[Sony Xperia S, Acro S, Ion] rkanwar:
What is alarm manager??
[Sony Xperia S, Acro S, Ion] harfot:
For managing alarms when you for axample want to wake up by music at specified time in the morning.
[Sony Xperia S, Acro S, Ion] rkanwar:
Oh okay. I dont think it has affected me. Overnight my battery lasts over 9 hours when I have an alarm set

If your android system or AlarmManager is giving you lots of usage or preventing Deep Sleep, Give this a read

I got 3 days of backup out of a single full charge with light use on sock ICS India (.452 build) rooted. My total usage includes 2hr45min of gsm calling, 1hr28min of screen on, about 20 min video + music playback. I got similar backup time on .73/.75/.76 GB but with much more usage (call time, screen on time) under similar conditions (i.e apps/games /settings). The difference is mainly in the battery drain by android os (which is way too high in ICS than GB). See screenshots below, second one is stock GB .73 rooted (which i uploaded here few months back).
[Sony Xperia S, Acro S, Ion] 3stage:
tbh the battery is my only dissappointing aspect of my S, went on a little road trip yesterday so thought i would give the satnav a little test, using Navfree, on a fresh install of stock ICS, nothing changed except removed the widgets from the homescreens and turned off wifi and data and it managed to eat the battery power from 100% to shut down in 4.5 hours!

now i bought the handset second hand so i dont know how well the previous owner looked after the battery, but it is not good.:crying:
[Sony Xperia S, Acro S, Ion] metcard:
gps will eat battery pretty quick on most devices.
[Sony Xperia S, Acro S, Ion] 3stage:
tbh your probs correct,but i have mainly used nokia devices before got my SXS, my last 2 were X6 32gb and a nokia N8 both of which would last 6/7hours + using gps with ovi maps
[Sony Xperia S, Acro S, Ion] metcard:
Yes. but the XS has a 720P 4.3 inch super bright screen.

The N8s brightness and resolution is nowhere near that of the XS. Maybe turn down the brightness a notch.
[Sony Xperia S, Acro S, Ion] 3stage:
yeah thats what i suspected seems the impressive screen in the S loves to eat the battery, is this a fault of the hardware itself or sonys choice to only use a 1750ma battery? hopefully there maybe some updates to the device regarding its power consumption

i would love to upgrade the battery, has anyone succesfully done this if there is a compatible uprated battery

Or just disable it/force stop.
[Sony Xperia S, Acro S, Ion] Dimitri.k:
Well my first Xperia S i got from the Sony store had the yellow tint issue & the battery would drain fast. It would be at 20% after 6 hours on heavy usage. Medium usage i would get around 8-9 hours. I sent the device in & they sent me a brand new one & this one seems to last longer. I go near 20hrs to a day with medium usage. Heavy usage i get around 15hrs which is pretty good for me without a charge. Both phones are running on .73. I have not gotten the ICS update yet here in Canada with Rogers..
[Sony Xperia S, Acro S, Ion] tel033:
Mine got worse still in. 75 cause ics seems worse and 15 hours or maybe 18 top but with 2g I have gsam battery monitor and go battery app don't know what else to do push only for whatsapp twitter and weather once an hour apart from that anything help!
[Sony Xperia S, Acro S, Ion] testadeferro:
I use a app called cpu sleeper.

This app shuts the 2nd core off when screen is off and it spares the battery.

Another thing that takes much battery is google maps. just freeze.

Now with .452 my battery life is about 20 hours medium use.
[Sony Xperia S, Acro S, Ion] rkanwar:
I think I will test this. Are there any specific settings
[Sony Xperia S, Acro S, Ion] 18lama:
Juice defender works really well.

Example

With JD the phone is able to go into deep sleep like it should normally but it wasn't.

If you compare this screen shot to the ones that people have posted you will see a lot of CPU wake events occurring and a lot of blue strokes appearing in the image.
[Sony Xperia S, Acro S, Ion] abajarde:
use power saver

my phone use to do that too but you if you leave it on overnight while not really using it, then you need to just set a time saver. basically you tell your phone from which time to which you dont use it, ie go to sleep, and the phone will stop processing data, syncing and stuff. I leave it like that from 12pm until 8am and its awesome. only loses about 5 percent from when i left it, try it, its pretty neat and it activates by itself
[Sony Xperia S, Acro S, Ion] utsav911:
ICS - battery eater

Well,

Since ICS update the battery drain issue has started again.

On .75 GB my phone's battery lasted at least a day, but i don't know what's wrong with ICS?

battery drops nearly 25% during night without any use. It never goes into deep sleepmode.

I am really worried as i could only use the phone for 4-5 hours with full charge. :(

If anyone has solution please help.

First thing to do is to set brightness lower.Then all you need to do is read a couple of pages back where everything has been explained a few times already ...
[Sony Xperia S, Acro S, Ion] utsav911:

[Sony Xperia S, Acro S, Ion] Kyrius:
well then, set the alarm manager to start when battery reaches 1% or better disable it, disable automatic synchronization, etc

and while i'm at it: secureclockservice was constantly keeping my XS awake so after i disabled it my battery life improved even further

What juice defender profile or settings are you using?
[Sony Xperia S, Acro S, Ion] tel033:
But juice defender shuts down data when screen is off right? Then I won't get any whatsapp messages if i don't constantly look at ny phone.. Is there an app that sets data to edge when screen is off and change to 3g when screen is on?

Is the disabling option only available in ics?
[Sony Xperia S, Acro S, Ion] fajarep:
i've been trying to smali fast-dormancy-wakeup.apk, i've seen a time that set the timer increase from 1 second to 31 second, but it seems, it still doesn't work, stopping the fast-dormancy service at ramdisk level only making log spam "can't access fast-dormancy" status. still hunting..
[Sony Xperia S, Acro S, Ion] Korumera:
Ok last night i've put the phone on airplande mode and just waited and see what will happen.

I've lost 5% in around 7 or 8 hours so that's alot better then it was. But samething weird is happening. Take a look at the first screenshot and then the second:

As you can see on the first screenie the awake state stopped but at the second one it says ingeschakeld (turned on) and then a blue line

So i think something is wrong with the radio in my phone
[Sony Xperia S, Acro S, Ion] mmonkiee:
I'm updated to .67 the battery life was much better after the upgrade, but still...

Went to hk Sony service center today and they said its normal to lose 20% overnight :-S
[Sony Xperia S, Acro S, Ion] Korumera:
Well it aint normal i can tell you that :) but i'm figuring out if it can be fixed without root (probably not tho)
[Sony Xperia S, Acro S, Ion] indesisiv:
Mine went from 84% down to 78% overnight, this is on stock, with about 90 apps installed. Only thing i do is leave it on 2g only and leave the wifi connected over night.

So it is definately not normal to drop anything near that.

Okay, thanks :D

I noticed that freezing it would make the Playstation App FC, that's strange :confused:
[Sony Xperia S, Acro S, Ion] deanfield:
I think I just have a new founding:

I found that my xperia s normally have 23 or 24 services running in the background (setting-application-running services). If I let those services running, the battery will drop about 20% to 25% for approx 7 or 8 hours standby (wifi, bluethooth and mobile network off).

But I just tried last night, I manually stopped many of those services and reduced to about 10 running services, my battery usage last night was only 2%. But I still don't know which service drains the battery most.
[Sony Xperia S, Acro S, Ion] Korumera:

Battery Life

2nd day of using my xperia S. The battery last only 7 hours tops. Nobody is calling me yet as it's a new number. Only 3G enabled, and yes, I lose about 20% overnight....

I'm charging it for 2 hours. After it reached 100%, re-plugged the adapter to continue charging.

If not, I'd try the draining method tomorrow.
[Sony Xperia S, Acro S, Ion] krohnjw:
Something has to be different here. I received the device yesterday, let it charge while using it during the day (on and off the charger several times). Charged it up before bed, used it some more. Went to bed at 90%. Slept for 7 hours - battery at 85%.

This is with 2 push accounts, on wifi. This is on par with every other Android device I've owned. Weather updating every 4 hours, BT off, GPS on. Nothing else updating in the background though.

I'll do the same on 3G tonight - I expect to see 2-3% / hr on 3G like I usually do with GSM devices.
[Sony Xperia S, Acro S, Ion] Alien987:
I should receive my XPS tomorrow or friday so I can't share my battery experience yet. But I think is important to expand on something that krohnjw implicitly is mentioning.

In my experience most modern devices will consume more battery when using 3G than Wi-Fi (or 2G), moreover if your 3G/2G/WiFi signal (whichever is active) is weak or fluctuating or your data connection too slow by any means this will consume more battery especially if you have push email accounts configured because it will force the phone to use more power to keep the push connection alive (or your syncs synced) while struggling with the poor data connection.
[Sony Xperia S, Acro S, Ion] doministry:
Quite right. The biggest usage is on data transfer.

But also look in menu, the screen is the biggest memory hog.
[Sony Xperia S, Acro S, Ion] sh500:
The postings here and in addition to almost every prominent industry review of the XPS is pointing to a poor battery life - the only thing so far preventing me from getting one.

Each to their own on how to save battery consumption - of course the HD screen would be expected to use some battery power, but the phone is a smartphone and suggestions to turn off 3G/WiFi when not needed, turn down brightness, etc should ought not be necessary in a smartphone in this day and age.

I can fully understand if people are getting a 7 hour battery life when the phone is in almost constant use, with videos, music, games, browsing etc. But from what I have been reading here and general reviews on the net, this device is achieving a low battery life with very moderate use it seems.

My only hope is as some people say, the battery improves over the first couple of weeks or/and Sony introduce a 'fix' either in Gingerbread or on the ICS upgrade.

The phone ought to comfortably last for a 24 hour period between charges on moderate to high use. This is of course based on an' average day with about 8-10 of those 24 hours spent sleeping (!)

Anyway, I am keeping a close eye on this thread and any other source regarding battery life. Keep the info coming, its much appreciated :)

I made an interesting and strange observation today.

I had my phone connected to 3G all day but kept wifi enabled and these are the results.

The phone sleeps normally and I get fairly decent battery life.

Keep awake 4minutes in 8 hours of normal use.

I then decided to turn WiFi off and left 3G data on... Here are the results.

Notice how the awake time jumps from 4 minutes to nearly 1 hour after 3 hours of disabling wifi :confused:

And Android system went from 2% to 7%
[Sony Xperia S, Acro S, Ion] Kyrius:
woooow thats strange ...
[Sony Xperia S, Acro S, Ion] rkanwar:
That is strange. Im going to check this out on my phone.

Here is my phone drain from 91% to 17% I unplugged at around 12.30 am and started using my phone at 9.30ish.

This is my battery after a fellow xda member suggesting the cpu sleeper app in this thread. Sorry I cant remember your name. Wifi on most of the time as well as 3G.
[Sony Xperia S, Acro S, Ion] borgsta:
Wow very interesting. I actually accidentally did it today (had tasker turned off) and I see my awakes are inline with the screen actually being turned on.

I can accept the screen on usage because it is a perfectly powerful device with a nice screen. But the lack of guaranteed deep sleep is very annoying.

Going to a music festival this weekend so I guess we shall see how long it can sit in my pocket with no internet and hardly any screen use before it dies. :p
[Sony Xperia S, Acro S, Ion] -Harsh-:
Strange for sure !!

Even i find it strange but happy too ;)

I kept the wi-fi on during the entire day and i used it as i use : 30 mins of calling, 2 hrs of music playback, 3 photos, using whats app for 10-15 mins (on 2G), texting 5-6, playing temple run for 14m precise, i also shared a Bluetooth file of 110 MB (took 8 mins) with my other phone.. And i was 90 % at 11:30 and was just 48% at 11:30 in the night !!

I kept the wi-fi on during the night without airplane mode and i lost 3% overnight.. (I usually lose 2%, in airplane mode)!!

Actually m more then happy coz i use a 1500mA charger of my sony handycam so it charges from 25-85% in 30-35 mins and i can use it easily for a day !!

I followed very simple instructions and I am loving my battery on ICS :)

Enable wifi and leave it on.

It seems like the wifi on this current firmware can't shut itself down properly or some other crap is going on which causes the phone to constantly wake when you disable wifi.

Ah thanks 18lama, I see you have jd ultimate, where as I've got jd plus.

Are you letting jd control your WiFi to or just your data?

Both.

But I don't use much data because of bad 2G/GPRS signals at my work place. Mostly it's wifi.
